This is WILD!
Goldman Sachs says Wall Street consensus 2027 hyperscaler Capex estimates are too conservative (Save this).
The consensus lands at $920 billion but Goldman thinks it could reach $1.4 trillion.
Here is how they get there.
Hyperscaler capex, the combined AI infrastructure spending of Amazon, Google, Meta, Microsoft, and Oracle went from $261 billion in 2024 to an estimated $805 billion in 2026, a 3x increase in two years.
The consensus for 2027 assumes growth decelerates sharply to just 22%, which is where Goldman pushes back.
Goldman economists compared that assumption against every major infrastructure buildout in history, railroads, highways, electrification, the internet and found they consistently consumed 2 to 3% of GDP at their peak.
At 2% of US GDP, hyperscaler capex reaches $950 billion in 2027 and at 3%, it reaches $1.25 trillion.
In the most aggressive scenario where hyperscalers deploy every dollar of operating cash flow plus the full capacity of the investment grade credit market, the number reaches $1.43 trillion.
The fourth chart is what makes the Goldman case feel earned rather than aggressive.
Hyperscalers are expected to reinvest 98% of operating cash flows directly back into capex in 2026, a ratio only ever matched during the telecom bubble of 2001.
The critical difference is that these companies are actually generating the cash flows that are being reinvested, Amazon, Google, Meta, and Microsoft combined are printing hundreds of billions in operating cash every year and putting nearly all of it back into infrastructure.
A buildout this large creates supply chain pressure and earnings volatility in the names most exposed, and Goldman is not dismissing that risk but the direction of spending is not in question, the only debate is whether 2027 comes in at $920 billion or $1.4 trillion.
The companies sitting directly in the path of that spending are the ones worth owning.
Nvidia captures the largest share of every hyperscaler capex dollar, owning 80% of AI training compute, and Morgan Stanley raised its 2026 capex estimate specifically because of continued Nvidia demand.
Oracle is the fastest growing capex spender among the five hyperscalers on a percentage basis up 116% from 2024 to 2027 with the smallest absolute base, giving it the most runway remaining.
CoreWeave and Nebius sit between the hyperscalers and frontier AI companies, renting GPU capacity to anyone who cannot get on the hyperscaler queue fast enough and as that capex number grows, so does their total addressable market.
