Why Chris Wood Warns the AI Boom Could Destroy Capital
Wood’s warning is about investment returns, not AI’s usefulness: cheaper models may pressure prices while US companies build costly infrastructure. If prices fall faster than usage and efficiency improve, data centre owners may struggle to earn back their investment; debt can make that shortfall harder to absorb.

Jefferies strategist Chris Wood’s warning is about whether the US AI buildout can earn an adequate return—not whether AI will remain useful. In his October 9, 2026 report, Wood argued that cheaper open-source Chinese models could take market share and contribute to “massive capital destruction” in the US.1
9 The concern is that competition may weaken pricing power after companies have committed heavily to infrastructure.
How cheaper models could squeeze returns
Wood’s argument has two linked parts: China’s models are cheaper, and China is increasingly seen as a technological peer to the US in AI, according to reporting on his note.4
9 If customers can switch to lower-cost models that meet their needs, US providers may find it harder to charge premium prices.
OpenRouter data can help show which models developers use through that platform. Its rankings count tokens processed through the OpenRouter API, so those figures are evidence about platform activity—not a direct measure of worldwide market share or how profitable any model is.28 Rising use can coexist with falling prices, but usage alone cannot show whether providers earn enough to cover the cost of serving those requests.
That distinction matters for infrastructure investors. More AI usage may increase demand for computing, but the return on a data centre or chip investment depends on the revenue it generates relative to construction, operating and financing costs. Lower prices can attract more use; they do not guarantee that the resulting income will repay the capital invested.
Why debt raises the stakes
Secondary reporting puts projected hyperscaler capital expenditure at about $695 billion in 2026 and $870 billion in 2027.7
17 These are forecasts, not realised spending, and they do not establish whether the investments will succeed or fail.
The risk Wood highlights becomes more acute as financing shifts toward debt. Borrowed money has to be serviced even if demand, prices or cash flows fall short. If lenders become less willing to finance new projects, companies may have to pay more to borrow or scale back investment. Brookings also describes a broader move toward joint ventures, private credit and special-purpose vehicles, which can make financing exposures harder to see.47
The result could be capital destruction without AI becoming a failed technology. Infrastructure might be used while still earning too little to justify what it cost to build. Brookings estimates that US investment in AI data centres, power systems, networking and chips could total $10.3 trillion from 2025 to 2032—a projection that underscores the scale of the investment challenge, not a prediction that the money will be lost.46

A long-term warning is not a crash date
Wood’s reported conclusion is framed as a likely long-term outcome, not a precise forecast of when a downturn will begin.1
9 Strong demand and continued access to financing can sustain investment even if the eventual returns are uncertain. The available reporting does not establish a date for a break in the boom.
Other market views illustrate that uncertainty. Panmure Liberum strategist Joachim Klement has been reported as expecting an AI bubble to burst in 2027 or 2028 and setting an S&P 500 target of 5,000; that is a separate forecast, not confirmation of Wood’s.50 Temasek’s investment chief has called an AI-trade reversal a major market risk while saying an unwind was not imminent.
30
The useful distinction is between AI’s potential value and the returns earned by the companies financing its buildout. Cheaper models could benefit customers while putting pressure on providers’ pricing. Whether that leads to capital destruction depends on how prices, usage, costs and financing evolve—not on demand alone.
