Jefferies’ Chris Wood warns US AI boom could end in massive capital destruction
Key Summary
Jefferies strategist Chris Wood predicts the US AI boom could end in massive capital destruction due to competition from inexpensive Chinese open-source models, which he expects to keep winning market share and drive down AI output prices. US hyperscalers have issued combined capital expenditure guidance of approximately $695 billion for 2026, projected to rise to $870 billion in 2027. Wood calls this spending 'malinvestment,' citing debt financing and potential credit risks. He advocates for 'picks and shovels' investments in semiconductor firms as a cautious approach.
Jefferies Warns of US AI Boom's Downfall
Spending That Worries Jefferies
Jefferies strategist Chris Wood is warning that the US AI boom could end in massive capital destruction due to competition from inexpensive Chinese open-source models. In his October 9, 2026, newsletter, he predicts that these models will continue to win market share and drive down AI output prices.
The Competitive Pressure
The spending that worries Jefferies is the combined capital expenditure guidance of approximately $695 billion for 2026, projected to rise to $870 billion in 2027. This figure covers the data centers, chips, and other hardware needed to rent out computing power.
Malinvestment
Wood calls this spending 'malinvestment,' an economist's term for money sunk into projects unlikely to earn back what they cost. He also points to how the industry has shifted towards debt financing rather than funding from cash.
A Different Kind of AI Race
Wood's argument shifts attention to economics, specifically who can deliver usable AI at the lowest cost per token. Open-source models matter here because they can be adopted widely without the same licensing arrangements as closed systems.
What This Means for Investors
For investors, the most immediate pressure point may be the balance sheet. If Wood is right, debt-heavy growth strategies could face increased scrutiny as market conditions turn less favorable for that approach.
Semiconductor Firms as a Cautious Approach
Wood advocates for 'picks and shovels' investments in semiconductor firms as a cautious approach amid increasing uncertainty. This approach focuses on supporting the infrastructure needed for AI, rather than building the AI itself.
