Including the full August 2025 tweet that I never posted below.
TLDR: I argued that the AI boom was structurally unsustainable: too much capital, too many undifferentiated โwrappers,โ and foundation models burning billions to subsidize usage. Since then, the bubble has inflated even further - AI firms pulled in the majority of global VC in 2025, while leaders like OpenAI blew past a $10โ12B revenue run-rate and still lost staggering amounts of money. Yet instead of a disciplined reset, investors have largely doubled down: lateโstage checks are still flowing into capitalโintensive platforms, mediocre appโlayer companies are limping through downโrounds, and only a thin slice of obviously broken wrappers is being culled. The early shakeout is real, but the capital allocation remains sloppy - far more driven by FOMO around a few brandโname winners than by rigorous views on unit economics or durable moats.
The AI Investment Supercycle Hypothesis - Mon, Aug 11, 2025
Hypothesis: The current boom in AI startups and funding is unsustainable. It will likely culminate in a severe capital crunch and mass consolidation or failure of AI companies, especially affecting growth-stage investors. Below we break down the thesis with supporting data and consider counterarguments.
Excess Company Count vs. Finite Market
Explosion of AI Startups: There are tens of thousands of AI-focused companies worldwide (~70,000 AI startups globally). Many of these are โAI-enabledโ software vendors whose products often rely on the same handful of AI models (e.g. OpenAIโs GPT). This surge echoes the dot-com era: โAI-powered is the new .com,โ with countless lookalike startups pitching similar ideas.
Limited Revenue Pool: The total AI hardware/software market is projected at $780โ$990โฏbillion by 2027. Yet venture capital and corporate investors have already poured well over $500โ600โฏbillion into AI companies to date . To justify these investments with typical 10ร returns, AI startups would need to generate on the order of $5โ6 trillion in revenue โ about 6ร the entire expected market size. In other words, the math doesnโt add up: there simply isnโt a large enough revenue pie for all these companies at their current lofty valuations. As Sequoia Capitalโs David Cahn noted, the gap between AI investment and revenue has ballooned into a โstaggering $500 billion annual revenue gapโ that must be filled to justify the spending .
Sky-High Valuations Assume Unprecedented Growth: Despite the limited market, funding has surged. Generative AI startups raised a record $56 billion from VCs in 2024 (885 deals) โ nearly double the prior year . Close to one-third of all VC funding worldwide went to AI in 2024 . These financings often came at inflated valuations (hundreds of millions or even billions), implying future dominance in their niches. Yet many have little proven revenue. An analysis in mid-2025 observed that โ90% of these โAI companiesโ are just expensive wrappers around the same five foundational models.โ In short, too many startups are chasing the same customers with undifferentiated tech, all while assuming theyโll each capture outsized revenue. This is structurally reminiscent of past bubbles.
Economics Inverted by Subsidies
Foundation Models Operating at Massive Loss: The core AI platforms (OpenAI, Anthropic, etc.) heavily subsidize AI compute costs to drive adoption. OpenAI, for example, generated about $4 billion revenue in 2024 but spent ~$9 billion to do so โ losing around $5 billion for the year. By one estimate OpenAI currently โspends $2.25 for every $1 it earnsโ. Similarly, Anthropic burned $5.6 billion in cash in 2024 while making well under $1 billion revenue . (Anthropic projects improving in 2025, but still expects to lose ~$3 billion on ~$3.7 billion revenue.) These eye-popping losses mean AI API prices are artificially low โ essentially subsidized by investors. The big model providers are keeping prices down to grab market share, even as they incur billions in operating losses.
Downstream โWrappersโ with No Moat: An estimated 30,000 software companies are โAI wrappersโ that simply call these foundation-model APIs and repackage the output with a pretty interface . Because they all rely on the same underlying AI engines, their products are often interchangeable โ โno IP, no moatโฆ just a well-structured API call, some markup, and marketing.โ Many charge high subscription fees (say, $50โ100/month) for services that a savvy user could replicate with direct API calls for a few dollars . This works only as long as OpenAI/Anthropic keep API costs low. When the subsidies inevitably end (i.e. prices normalize upward to cover real costs), these downstream startupsโ economics collapse. Their entire model is built on thin margins. As one analysis put it, โevery token sent through a wrapper โ paid or not โ earns OpenAI moneyโฆ startups become unpaid distribution arms, subsidizing OpenAIโs growth while bleeding out.โ In other words, the house (OpenAI) always wins โ until the โwrappersโ run out of cash. At that point, thousands of these dependent products will either have to raise prices (driving away customers) or shut down.
The Commoditization Spiral: The combination of ubiquitous tech and underpriced service creates a vicious circle for most AI vendors: (1) If everyone uses the same few AI models, products become undifferentiated. (2) Competing on features is hard, so pricing wars ensue โ indeed, OpenAIโs latest GPT-4 price cuts undercut Anthropic by up to 7ร on cost per token, forcing others to match or lose business. (3) As prices per customer plummet, so do gross margins for any startup reselling AI. (4) Lower revenues make it impossible to support the previous valuations or to cover the still-high infrastructure costs (AI compute remains expensive, and energy/compute costs are not falling as fast as pricing). (5) With unit economics turned upside-down (more users actually increase losses), these companies cannot sustain operations without continual investor subsidies. This โrace to the bottomโ on price is great for end-users in the short term, but itโs lethal for the thousands of me-too vendors. Itโs analogous to the dot-com era of free services: eventually the money runs out.
Growth-Stage Capital at Extreme Risk
Late-Stage Funding Frenzy: Unlike early-stage VCs who place many small bets, growth equity investors have been writing big checks (often $25โ100 million each) into mid-stage AI companies at $400 million valuations. These rounds (Series B, C, D etc.) were justified by lofty growth assumptions and the fear of missing the โnext big thing.โ However, many of these startups have 8โ12 month runways due to high burn rates (expensive ML talent and cloud bills) โ meaning they will need another funding round by 2024โ2025. For example, in 2023โ24 numerous generative AI startups raised funds at unicorn valuations despite minimal revenue, and immediately ramped spending on AI infrastructure. โMost companies funded during the 2021โ2023 boom had 18โ36 months of capital,โ and many will run dry by late 2025 or early 2026 if they canโt refinance . The growth investors who led these big rounds will be left holding the bag if valuations reset.
High Failure Rates = High Write-Downs: Early-stage venture firms expect e.g. 6 or 7 out of 10 startups to fail โ their model tolerates it. Growth equity, in contrast, bets on a much lower loss rate (maybe 1 or 2 failures out of 10) because they deploy larger sums per deal. The current AI cycle is likely to betray those expectations. Industry observers predict over 90% of AI startups will fail within five years. Even before the recent frenzy, tech market indices showed sharp private valuation declines in 2022โ23 , and many AI firms that raised in 2024 have since missed milestones. If 80โ90% of funded AI companies ultimately go under, growth-stage funds with heavy AI exposure could see well over half their portfolio by value written off. In effect, billions in late-stage capital could evaporate. Estimates of the โdead moneyโ vary, but even a conservative scenario of 60โ70% startup failure would wipe out ~$400 billion (out of ~$600B invested), and a more realistic 80โ90% failure rate implies $500B lost. Indeed, PitchBook data show fundraising for AI has already dropped in 2024 (deal count down 42%) as reality sets in . Growth investors are slamming on the brakes, but it may be too late โ the capital is already in these companies, and many are running on fumes.
Compression of Exit Options: Another challenge for growth equity: who will buy or IPO these companies to provide an exit? The IPO window for tech is cautious in 2025, and the few public listings (e.g. Cloud, enterprise AI) have not delivered the kind of multiples needed. M&A is an option โ and indeed we may see rapid consolidation in 2025โ2027, with stronger players acquiring distressed startups for pennies on the dollar. But most acquirers will wait until valuations crumble. Funds that put $50M into a โnext-generation AI SaaSโ at a $500M valuation may recoup only a fraction in a fire sale. The timeline looks grim: 2025 will likely still see some aggressive fundraising and peak company counts, but by mid-2026 signs of saturation (slowing growth, rising customer-acquisition costs) will be undeniable. By 2027, as startups exhaust their last cash, we could witness a mass shutdown wave โ potentially thousands of AI companies closing within 12โ18 months . Growth equity portfolios will be forced to mark down failing investments (60โ90% losses in the worst cases). As one industry veteran wryly noted, โFunds with 40% of their book in AI might experience a 80% write-down in that slice โ itโll be historic.โ
Timeline: From Bubble to Shakeout
2021โ2023 โ Build-Up: Breakthroughs in generative AI (GPT-3, DALL-E, etc.) trigger a flood of startup creation and funding. Valuations skyrocket on hype. Investors cite โAI is the new electricity,โ and fear of missing out leads to overfunding of very early-stage projects . Many companies launch with little more than a demo or a fine-tuned model wrapper.
2024 โ Peak Froth: Funding reaches record levels (as noted, $56B VC dollars into genAI in 2024 ). By late 2024 and early 2025, AI headlines dominate tech. But underneath, cracks appear: infrastructure bottlenecks (GPUs), first reports of AI startups with negligible traction, and Big Tech (OpenAI, Microsoft, Google) racing ahead of the pack. The largest AI firms themselves remain unprofitable despite fast-growing revenue โ e.g. OpenAI doubled its ARR from $6B to $12B in the first half of 2025 (annualized run-rate), yet it continues to burn cash ($14B loss expected in 2025). This suggests even market leaders havenโt found efficient economics yet.
2025 โ Early Signs of Saturation: By mid-2025, the number of AI products on the market has exploded. Every sub-sector (coding assistants, AI content generators, chatbots for support, etc.) is crowded. Customer adoption, while real, cannot keep up with the supply of solutions. Anecdotally, sales cycles for B2B AI software start to lengthen as CIOs get fatigued by thousands of similar pitches. Customer acquisition cost (CAC) rises โ more effort needed to convince users who have already tried 5 different AI copywriters or coding copilots. Big Tech enters aggressively, bundling AI features into their platforms (often free or at low cost), undercutting standalone startups. Investors grow more selective, favoring startups with real differentiation or proprietary tech.
Late 2025 to 2026 โ The Crunch: This is when the โgravityโ of finite capital hits. Many startups that raised in the 2021โ22 boom face end of runway by late 2025 . Unfortunately, the funding environment now is much tougher โ interest rates are higher, and LPs (the investors in VC/Growth funds) are nervous about overexposure to AI. We can expect a sharp pullback in new funding for all but the top 5% of AI companies. The rest must either find an acquirer or drastically cut costs to survive. In mid-2026, weโll likely see a wave of down-rounds (companies raising capital at much lower valuations) and outright failures. Investor sentiment flips from FOMO to caution: as one VC noted, โthereโs far more scrutiny on unit economics and revenue tractionโ now . The mere mention of โAIโ no longer secures a premium โ in fact, hype-y startups are viewed with skepticism unless they have solid metrics.
2027 โ Mass Extinction Phase: By 2027, the global liquidity squeeze is in full effect. Earlier-stage VC funds may have the dry powder to prop up a few of their best bets, but growth equity and crossover investors (who fueled the largest rounds) largely retreat, nursing losses. Without new funding, thousands of AI startups will fold in a short period โ the โbursting of the AI bubble.โ This is analogous to the dot-com crash circa 2000โ2001, when countless internet startups went under. The survivors likely fall into two camps: (a)Infrastructure-level players (the big foundation model providers or cloud platforms โ many of whom are incumbent tech giants or heavily funded leaders like OpenAI), and (b)a handful of startups with truly defensible, domain-specific AI solutions (e.g. a company with a unique dataset or enterprise integration that gives it an edge in a niche). These survivors might consolidate the market โ mergers and acquisitions spike as the stronger firms acquire IP/talent from failed ones for pennies.
2028โ2029 โ Reset and Renewal: In the aftermath, the AI industry will likely look very different. Having shed the excess, the remaining companies can actually start to approach sustainable economics. With less crazy competition, pricing power returns for the winners โ e.g. API rates may rise to profitable levels once only a few providers dominate, and enterprise software firms that survived can charge more rational prices for clear value-add features. We may see public-market validation for a few big winners (think of how Amazon and Google emerged from the dot-com ashes). Meanwhile, many VC funds will report poor returns for their AI bubble-era cohorts, leading to a period of caution (and perhaps fewer new AI funds being raised for a while). In industry terms, this phase is healthy: it allows the real demand to catch up to the technology and for business models to mature without the distortion of easy money.
Endgame: Fewer Winners, Saner Market
When the dust settles, three forces likely hit simultaneously:
Valuation Collapse: Private and public market valuations for AI companies revert to levels based on fundamental metrics (revenue, margins) rather than hype. Multiples compress dramatically. For example, AI startups that raised at 100ร forward revenue might trade at 5โ10ร (in line with normal software firms) if they survive at all. This repricing can be swift and brutal โ weโve already seen some high-profile AI unicorns take down-rounds or markdowns in 2024โ25. The broad NASDAQ tech market fell ~33% in 2022 , but many private AI valuations could fall far more (70โ90% in some cases) before finding a floor. Investors essentially write off the bubble-era paper gains.
Mass Company Closures: As described, a huge percentage of AI startups will likely shut down within a yearโs span (the โmass extinctionโ). Weโre talking not just dozens but potentially thousands of companies disappearing. One mid-2025 report already warned that โover 90% of AI startups fail within five yearsโ. This winnowing will be painful for employees and investors in those firms, but it is the marketโs way of clearing out ventures that never found product-market fit or a path to profitability. Itโs worth noting this doesnโt mean the technology goes away โ often the IP or talent from failed startups is absorbed by larger players. But as stand-alone entities, most will be gone. Growth equity funds with heavy AI portfolios will have historically large loss ratios, as discussed.
Industry Reset & Sustainable Growth: With far fewer players, the survivors can capture larger shares of customer demand. Pricing will likely increase once subsidized competition fades โ e.g. the major AI cloud providers may raise API prices to finally earn a cloud-like margin on AI services, and surviving SaaS companies will focus on customers who are willing to pay for proven ROI. Weโll also see a narrowing of features to what customers actually use and value. During the hype phase, many startups added โAI featuresโ that were more gimmick than necessity. Post-shakeout, the focus will be on core uses that deliver business value (since those are the ones customers continue paying for). In effect, a handful of โmega-winnerโ companies (likely the cloud/platform giants and a few specialized firms) will dominate, and they will have learned how to make money on AI. Margins for these survivors could improve significantly due to reduced competition and higher efficiency. For example, if OpenAI and one or two peers end up providing 90% of global AI API calls, theyโll have the market power to charge profitable rates (unlike todayโs loss-making prices). In enterprise software, a few AI-enhanced incumbents (or well-capitalized startups) will bundle AI capabilities as part of larger offerings, enjoying upsell revenue without having to support a standalone 50-company ecosystem in each niche. In summary, the bubble subsidy will be gone, but the truly useful AI applications (and companies) will remain and thrive under more rational economics.
In essence, the industry will have undergone a Darwinian culling โ leaving a leaner ecosystem where: a) far fewer companies serve the real demand, b) capital investment is aligned with actual revenue potential, and c) infrastructure providers can operate profitably (no longer incentivized to burn $1 to make 50 cents).
Counterarguments & Considerations
Itโs important to acknowledge that this hypothesis is intentionally bearish and not universally held. There are more optimistic takes on the AI marketโs trajectory:
AI Market Could Expand More Than Expected: The forecasted ~$800Bโ$1T market by 2027 might prove too conservative. AI is a general-purpose technology that could spawn entirely new industries and revenue streams by 2030. Some proponents argue we are underestimating AIโs total addressable market โ citing, for instance, that AIโs total economic impact (including productivity gains) could be $15 trillion to global GDP by 2030. If even a fraction of that is captured as revenue, the pie might grow enough to support more companies (though likely not 70k startups). The analogy is the Internet: early projections in the โ90s didnโt foresee trillion-dollar markets in e-commerce, cloud, online advertising, etc. Could AI likewise surprise to the upside? Itโs possible that new killer apps (e.g. AI in healthcare, finance, etc.) will unlock revenue sources that justify some of the current investment.
Extraordinary Growth of Leaders: While most AI startups struggle, the winners are growing at jaw-dropping rates. OpenAIโs revenue run-rate jumping from ~$1B to $12B in roughly a year shows that demand for top-tier AI services is real and accelerating . Anthropic similarly went from near-zero to a $5B ARR in 2025 by focusing on enterprise coding assistants . If a few companies can indeed each capture tens of billions in revenue, the overall sectorโs revenue โceilingโ moves higher. This concentration of success might mean the total AI sector revenue in 2027โ2030 ends up far larger than the average of individual forecasts โ essentially, a power-law outcome where a handful of firms achieve what dozens of smaller players had hoped to. For growth equity investors, a single big win (say, backing the next Nvidia or the next Salesforce-level AI platform) could make up for many losses. Thus, the doomsday scenario for every investor isnโt assured; it depends on whether they picked any winners.
Strategic Value and Big Tech Support: Not all AI companies live and die by immediate unit economics. Some are being kept afloat by strategic partnerships or acquisitions. For example, cloud giants (Amazon, Microsoft, Google) have strong incentive to subsidize promising AI startups via cloud credits or investments, because those drive cloud usage and ensure the tech stays out of competitorsโ hands. We are seeing collaborations like Nvidia investing in certain AI startups or Microsoftโs multibillion funding of OpenAI, which indicate that big players will absorb huge costs to remain leaders . This means some of the heavily lossmaking AI firms might not face a hard stop in funding โ they could be acquired or continually bankrolled as strategic assets. In the endgame, one could envision a scenario where Big Tech effectively โacqui-hiresโ much of the AI startup talent/IP (at lower valuations), softening the blow of the bust. The survivors might mostly be divisions of larger companies.
Historical Precedent โ The Dot-Com Lesson: The dot-com bubble crash saw ~75% of internet companies fail, but those that survived (e.g. Amazon, eBay) went on to be monstrously successful, and the internet did indeed transform the economy. Analogously, even if 90% of current AI startups fail, the 10% that survive could form the backbone of the next decadeโs tech giants. From a consumer and societal perspective, the AI revolution will likely continue its momentum (AI adoption in business is still growing in 2024โ25 ). The โboom/bustโ cycle might just be a necessary phase of maturation. So a counterpoint is: yes, weโll see a painful consolidation, but no, itโs not the end of AI innovation or investment. It may actually be the beginning of a more stable growth phase, much like web 2.0 rose after the dot-com washout.
In summary, skeptics of the thesis would agree thereโs excess in the short term, but suggest the long-term opportunity of AI remains enormous. They argue the current shakeout is part of separating signal from noise. A few dominant platforms (possibly todayโs front-runners or yet-to-emerge dark horses) could justify the overall investment by eventually generating massive profits โ even if 90% of their contemporaries fail. Thereโs also the possibility that new waves of AI advancement (e.g. AGI or breakthrough applications) could reignite growth before a full bust occurs, prolonging the cycle.
Conclusion: A Probable Reckoning (with a Silver Lining)
The evidence strongly indicates that the AI sector is in a classic boom-to-bust cycle. Too many companies are chasing too little near-term revenue, propped up by an infusion of capital that cannot possibly see 10ร returns across the board. The unit economics for most AI startups are unsustainable โ many are effectively selling dollars for cents, subsidized by investor cash. And while innovators like OpenAI have achieved remarkable technological feats, even they have yet to prove a profitable business model under current pricing. All this suggests an inevitable shakeout: absent โcontinuous subsidizationโ by investors, the market will force a correction. We are likely to witness a wave of consolidations and failures in the next 1โ3 years that mirrors the dot-com collapse in scope. Growth-stage investors, in particular, are poised to absorb heavy losses as valuations normalize and weaker companies fold.
Importantly, this is not a thesis against AIโs significance โ itโs a reality check on AI as a business. The technology is revolutionary; the mistake is assuming every AI company will be. The math has the final say. As one observer neatly summarized: โToo many companies for the available spend, too much capital chasing too small a market, and too much dependency on unprofitable infrastructureโ โ something has to give. And that โsomethingโ will be the hundreds of AI startups that never had a viable path to profits.
What comes after the crunch? Likely a healthier, more mature industry. The survivors โ perhaps a few large-scale AI platforms and select specialized firms โ will benefit from reduced competition and clearer value propositions. With saner valuations, they can grow with realistic expectations and sustainable margins. For investors and founders, the coming storm will be painful, but it will also clear the way for the next phase of AI innovation grounded in real economics. In the long run, AI isnโt going anywhere; it will be as transformative as promised โ just not in the form of tens of thousands of unprofitable startups. The current thesis appears largely correct in diagnosing the excesses. The prudent move now is to adjust messaging and strategy accordingly: emphasize real use-cases and unit economics, prepare for tighter funding conditions, and focus on building or backing the few AI companies that can emerge on the other side of the capital crunch as true winners . The era of indiscriminate โAI hypeโ investment is winding down; what follows will separate the enduring players from the rest.
In August, I wrote this but never sent it.
Publishing it felt like bad business. The very funds I was warning might lose were, and still are, key clients for Crossover Research. So I stayed quiet.
But staying quiet no longer feels right.
With software multiples down more than 30% across the board, and analysts calling this the SaaSpocalypse, the reckoning I expected has arrived. This is not a macro correction. It is not rates, inflation, or demand softening. It is structural. AI is not just competing with enterprise software; it is replacing it. The perโseat model that powered twenty years of SaaS growth is collapsing as agents bypass the interface entirely and operate directly on the data.
Salesforce, ServiceNow, Adobe, and Workday are all down 40% or more from recent highs. Thomson Reuters fell 16% in a single session after Anthropic released its legal agent. The room I once hesitated to rattle has already been rattled. The math has not changed since August. Only my willingness to say it out loud has.
The Thesis
AI acceleration is collapsing the cost of creation and narrowing the gap between โbuildโ and โbuy.โ The winners will be those that:
> Own missionโcritical workflows: controlling the system of record where business logic and risk live.
> Capture proprietary, permissioned data feedback loops: continuously refreshed, highโsignal data that compounds advantage over time.
> Convert trust and embeddedness into pricing power: turning reliability, compliance, and integration depth into premium retention.
Everything else will be repriced toward zero.
Four structural realities:
1. Commoditization crushes undifferentiated software. Vendors competing on price or easily cloned features face accelerating margin compression as AI drives timeโtoโparity toward zero. Only those with differentiated ROI, deep workflow embed, or regulatory trust sustain pricing power.
2. Enterprise exposure is a time moat, not a permanent one. Integration and compliance slow churn but do not stop it. As agentic AI removes implementation friction, retention will flow toward vendors that own the workflow, not those that simply serve large customers.
3. Buildโcost compression redefines survival. Standโalone tools and UXโfirst point solutions are first to fall. Platforms that control data, compliance, and execution layers, the true systems of record, will outlast the rest.
4. Proprietary data feedback loops are the modern moat. Durable software compounds advantage through exclusive, selfโreinforcing data capture that directly improves outcomes and compliance intelligence. Raw data volume is no longer defensible; uniqueness, context, and feedback velocity define resilience.
What this means for diligence
This is exactly the question Crossover Research was built to answer for PE and growth investors: not whether a vendor looks sticky on paper, but whether customers prove the moat through workflow embeddedness, data defensibility, pricing leverage, and displacement risk.
We have built a Voice of Customer diligence engine to make that visible [
