Jeff Bezos just came out of retirement. His first CEO role since leaving Amazon. And he's building something nobody expected. 🤯 It's called Prometheus. $12 billion raised. $41 billion valuation. Backed by JPMorgan, BlackRock, Goldman Sachs, and Bezos himself. 150 employees. $273 million per person. That's how much investors are betting on this. But here's what makes it different from every other AI company. Prometheus isn't building another chatbot. It's not generating text or images. It's building what Bezos calls an "artificial general engineer" AI that designs jet engines, optimizes manufacturing, and prototypes physical products. LLMs learned from the internet's text. Prometheus is learning from the physical world physics, simulations, engineering data, manufacturing processes. In Bezos' own words: "Something that takes 100 engineers 10 years to build we want to make that 10 engineers, one year." His co-CEO is Vik Bajaj, former Google X executive who worked with Sergey Brin on what became Waymo. No ties to Amazon. No ties to Blue Origin. Bezos said "it deserves a dedicated team obsessed with this one thing." While everyone is racing to build the best AI for words, Bezos is quietly building AI for the physical world. That might be the bigger bet.

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees. The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance. Access to all other Claude models is not affected. We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible. Read our full statement: anthropic.com/news/fable-myt…

Elon just created 4,400 millionaires in a single day. 400 of them are now worth over $100 million. These aren't VCs. They're SpaceX employees, and the list includes welders, technicians, and cafeteria staff, because for two decades the company paid every level of the workforce in stock instead of higher salaries. Juan Hernandez immigrated from Mexico and took a $28 an hour contractor welding job in 2015. He says he didn't even know what SpaceX was. The company gave him a $10,000 equity grant and let him buy more shares through payroll deductions. That stake is now worth $880,000. Trevor Hise's parents wanted him to take a stable job at General Electric. He picked SpaceX instead, stayed 12 years, and accumulated over 100,000 shares. At the $135 listing price that's $13.5 million. He's 37 and semiretired. His words: "The magnitude of this has been ridiculous." The most telling detail came before the listing. Over 100 employees quietly banded together and negotiated a group wealth management deal covering up to $5 billion, because none of them had ever needed a wealth manager before. Software IPOs have minted millionaires for 30 years. This is the first one where the money went to the factory floor.

This is wild. And it's exactly why SpaceX IPOs in 3 days. SpaceX just unveiled AI1: one computer rack strapped to a 230-foot solar wing, with a plan to fly a million of them. On its face it reads as a satellite reveal. Read the timing and it's a pitch deck. The company prices June 11 at a $1.75 trillion valuation, raising $75 billion, already two times oversubscribed. Rockets and Starlink don't get you to $1.75T. Orbital AI compute might. Here's the bridge. That 150 kW is roughly a single NVIDIA GB300 rack, nothing special sitting on the ground. The spec that actually matters is 70 kW per ton. On Earth, the constraint on AI is power. You build next to a substation and wait years in an interconnection queue for the utility to hang enough transformers. The megawatts are the bottleneck, not the chips. At 600 km that goes away. Sunlight is constant and free, the 230-foot wing is the power plant, and it ships attached to the rack. The only new problem is heat, which is why the thing is almost entirely panel. So the whole bet collapses to one number that has nothing to do with AI: the cost of putting a kilogram into orbit. Get Starship cheap enough and a watt of solar compute in space underprices a watt trapped behind a transformer queue on the ground. That's the story they're selling 3 days before pricing: they own the only rocket cheap enough to turn free sunlight into the cheapest compute on Earth, and nobody else can copy it. A million satellites is 150 gigawatts of compute that never touches a power grid. That's the actual IPO.
JUST IN: SpaceX officially unveils AI1, its first AI satellite, with up to 150,000 watts of compute payload.

BREAKING: Anthropic just dropped Claude Fable 5—this is Mythos, made safe for public release. It is the best coding model in the world. We've been testing it internally @every for the last week or so across coding, writing, marketing, editing, and more—here's our vibe check: - It broke our benchmarks. Fable scored a 91/100 on our Senior Engineer benchmark—this is human senior engineer level. The previous high score was Opus 4.8 at 63. GPT-5.5 is a 62. - It's a one-shot wonder. You can set it and forget for hours or overnight on huge coding tasks, and come back to completed work. It cleared entire production bug backlogs, built a playable 3D, and even made a 2-minute animated film—all one-shot. - Taste and attention to detail. In coding and knowledge work tasks, it has much better taste and attention to detail than we've ever seen. It gets subtle things right, adds little features you might not have thought of, and generally understands the assignment in ways that surprised us. - Great use of context. We set it loose analyzing customer feedback surveys and our website data and it came back with a crisp, clean report that identified a. our biggest problem and b. a concrete testable solution—and then we sent it off to build that. - It's best for power users. If you're already used to orchestrating multiple agents in your work, this model can do things that you've never seen before. If you're a knowledge worker or vibe coder with a more basic setup, you're not going to notice a huge difference—in fact, it probably isn't the right model for you. - It's very slow, token-hungry. Using this thing for regular knowledge work is like squashing an ant with a rocket launcher. It also routinely uses 500k to 1M tokens on tasks. That's why it's best for your heaviest jobs—but not as good for tasks like collaborative writing. - It's expensive. It's about twice as expensive as Opus, and it's also incredibly token hungry—so expect it to be something you'll use sparingly unless your company pays for it. Overall, I think of it like a warp drive for coding: It can get you across the galaxy in a few hours, when it used to take months or years. But it's not appropriate for getting around town—you need something faster, cheaper, and more maneuverable. The ceiling is extraordinarily high on this model though. Even our most advanced testers like @kieranklaassen felt like they were only scratching the surface of it. Want our full vibe check with all of our testing and benchmarks?

Mark Cuban just described the largest wealth transfer of the AI era. Almost nobody understood what he said. Cuban: “There are 33 million companies in this country. Aren’t going to have AI budgets. Aren’t going to have AI experts.” Not tech startups. The shoe store. The regional trucking outfit. The accounting firm with 12 employees. The businesses that actually run the physical economy. They know AI is coming. They have no idea what to do with it. Cuban: “You’ve got the head of Microsoft saying software is dead because everything’s going to be customized to your unique utilization.” Software is dead. The SaaS era ran on one rule. Build a generic product. Force millions of companies to bend their workflows around it. Charge rent forever. AI ends the contract. The business stops bending to the software. The intelligence bends to the business. But customized by whom. The third-generation manufacturer cannot tell Claude from Gemini. The county hospital is staring at a reactor asking where the light switch is. Cuban: “Who’s going to do it for them?” That question is worth more than the frontier models themselves. Hundreds of billions are being burned to build the foundation. The smartest engineers alive are locked in a bloodbath over who owns the base layer. Let them fight. Let them burn the capital. Let them drive the cost of raw intelligence toward zero. Because the wealth does not collect where the brain is built. It collects where the brain meets the business. Every ambitious kid in college right now thinks survival means a seat at OpenAI or Anthropic. Cuban is staring at the other 99 percent of the economy. Learn the models. Then learn the messy, unglamorous reality of how a 50-person company actually operates. Walk through the door. Understand their problems. Wire the intelligence directly into their revenue. That is not a job title. That is an entire economic class being born. You do not need to build the brain. You need to build the nervous system. The biggest winners of the electricity era were not the engineers who built the generators. They were the ones who walked into dark factories and showed the owners where to plug in. 33 million companies are standing in the dark right now. Silicon Valley is racing to build the god. The fortunes will belong to whoever teaches him a trade.

Clubbing is dead and has been replaced by fitness & wellness. Ppl used to party to socialize and date but now they do things like HYROX, bathhouses, and running raves. The death of clubbing is something to be studied: — US has lost 12% of its nightclubs in the last 24 months — 25% of US adults didn’t drink at all last year — Gen Z drinks 30% less than Millennials did at the same age On the flip side: — According to Strava, the number of running clubs recorded on the platform increased 3.5x in 2025 — 72% of Gen Z go to run clubs to meet new people — Sauna and spa market: $11.8B → $22.4B by 2034 The post-alcohol economy is gonna be a massive category.

🚨 do you understand what just happened with the SpaceX IPO.. Fidelity quietly dropped its minimum account requirement from $500,000 to $2,000 - a 99.6% cut that lets millions of small retail investors in days before the biggest stock debut in history. The catch is who they need to sell to. - SpaceX reserved up to 30% of the offering for retail, far above the usual single-digit share - Selling within the first 15 days triggers Fidelity penalties up to a permanent IPO ban - At a ~$1.675T pre-money valuation this IPO creates more exit value than every VC-backed IPO of the last decade combined - The xAI side lost $6.4B from operations in 2025, dragging a Starlink-powered company billions into the red They opened the gates right when the smart money needs someone to sell to. Read the prospectus before you become it.
NEW: Fidelity lowers the minimum account requirement for the SpaceX IPO from as high as $500,000 to just $2,000.

A scientist in Denmark figured out how to make Claude prepare his job applications. He open-sourced the whole thing. His name is Mads Lorentzen. He is a PhD geophysicist. He built it on top of Claude Code and released it under MIT license. Here is what it does. You fork the repo, fill in your background once, and it runs a five-step pipeline for every job you want to apply to. Step 1. It reads the job posting and scores how well you fit. Step 2. It drafts a tailored CV in LaTeX, picking only the experience that matches. Step 3. It writes a cover letter framed around what you would bring to the role. Step 4. A second AI agent reviews the first agent's work, points out weaknesses, and the first agent revises. Step 5. It compiles both into clean PDFs you can send. The whole thing is a folder of markdown files. The candidate profile, the writing style rules, the CV templates, the interview prep notes. Every step is plain text you can read and change. The job portal search is built for Danish boards. The application workflow itself works for any country. 489 stars. 270 forks. A fork-to-star ratio that high means people are using it, not only bookmarking. Mads is not a startup founder. He built this because he needed it for himself, then shared it. This is the future of job hunting. Not a service you pay for. A workflow you own. (Link in the comments)

I spoke with a member of the technical staff at Anthropic yesterday who is about to make $17 million. He's been there less than 2.5 years and is blown away by his equity value. His biggest worry now is tax strategy. His CPA told him to "max out his 401(k) and consider a donor-advised fund." While that's a great starting point, here's what makes even more sense: He's acquiring a 48 unit apartment complex in Phoenix for $14.5 million. We're running a cost segregation study to reclassify approximately 30% of the depreciable basis into 5, 7, and 15 year property. Here's the math: • $14.5M purchase price • ~$12.3M depreciable basis (excluding land) • ~$3.7M reclassified to short-life assets via cost seg • 100% bonus depreciation under OBBBA = $3.7M accelerated to Year 1 Plus standard Year 1 depreciation on the remaining basis adds another ~$315K. Total Year 1 deduction: approximately 4M. His wife is qualifying as a real estate professional 750 hours, more time than any other activity. The loss is no longer passive. It offsets ordinary income. At a 37% federal bracket plus 13.3% California, that's a combined rate just over 50%. $4M × 50% = 2M in tax savings. Year 1. Layer in operating expenses, loan interest, and startup costs on the property, the total offset against his Anthropic income crosses $3 million. Not deferred. Not spread over 27.5 years. Meanwhile, the property cash flows. He's converted concentrated tech stock into a real asset producing monthly income. And he's done it all before he files the return on his equity windfall. This is what real tax planning looks like for tech liquidity. If you're an engineer, exec, or early employee sitting on a meaningful equity position and your CPA hasn't mentioned cost segregation, bonus depreciation, or REPS qualification, you're probably leaving seven figures on the table.

THIS GUY LIVES UNDER SFO'S TAKEOFF PATH SO HE BUILT A CEILING PROJECTOR THAT TRACKS EVERY PLANE FLYING OVER HIS HOUSE IN REAL TIME he uses a cheap $30 radio receiver to pick up the signals that planes broadcast while flying. then projects them onto his ceiling in real time when a jet flies over his house you hear it outside and at the exact same moment a plane glides across his ceiling labeled with the airline, aircraft type, and destination pure black background so the projector's rectangle disappears and only the aircraft are visible but he didn't stop at planes it also draws the real sky behind them. sun, moon, bright stars, constellations, and live satellites including the ISS. all at their true positions for his exact location and time in real time so he's lying in bed watching the actual night sky projected onto his ceiling with real planes crossing through it as they take off from SFO there is a huge market for every man alive that runs outside to see the helicopter vibe coded the whole thing himself with a cheap radio, a projector, and some clever software

Jensen Huang says that investing in the IPOs of SpaceX, Anthropic, and OpenAI will be like buying $AMZN, $GOOGL, or $META in their early stages. Don't become a victim of FOMO. IPO day is not where the best opportunities are made. In many cases, there's a massive spike followed by a sharp decline that takes the stock below its IPO price. Just look at $META. After its 2012 IPO, the stock lost more than 50% of its value within three months. The best opportunities come when the hype is gone, sentiment turns negative, and nobody wants to touch the stock. That's when I'll be buying heavy.
