AI Companies Lean on Debt as Rising Yields Raise the Cost of Growth

The Nasdaq 100 lost about 5.5% in a single week, its steepest weekly drop since the March 2025 tariff selloff, as a surge in crude oil revived inflation fears across U.S. markets. AI company debt sits directly in the path of that pressure, because firms that borrow heavily to fund growth pay more when inflation keeps Treasury yields and Federal Reserve rate expectations elevated. Names such as CoreWeave and Anthropic depend on debt to bridge the gap between heavy spending and future profit. Each move higher in borrowing costs makes that bridge more expensive to cross.

James Stanley, StoneX Media Senior Market Analyst, has tracked markets for more than two decades, starting in equities and expanding into options, fixed income and foreign exchange. His work centers on price action and macroeconomics over medium-term time frames, following how shifts in inflation, interest rates and commodities filter through to equity valuations.

Key Themes

• AI companies rely heavily on debt, so higher interest rates raise their cost of funding growth.
• Rising crude oil prices feed inflation and add pressure on the Federal Reserve to hike rates.
• Higher borrowing costs mirror the pressure that took down dot-com companies in 2000.

AI Company Debt Turns Rising Rates Into a Profit Deadline

AI company debt has become a central vulnerability for the sector, as demonstrated by a leaked Anthropic IPO prospectus showing an annual loss of roughly $42 billion. "Where's the gap getting filled from here? From debt," Stanley says, adding that "the higher that rates go, the more pressure is on Anthropic to actually produce profit." CoreWeave shows the same mechanics, with the AI cloud provider paying more to finance its operations as yields have climbed. For AI firms still burning cash, every increase in rates narrows the window to reach profitability.

Crude Oil Prices Push AI Borrowing Costs Higher Through Inflation

Crude oil prices connect the energy market directly to AI company debt, since higher fuel costs feed inflation and inflation shapes the path of interest rates. Much of what U.S. consumers buy reaches its destination by truck, running on diesel and gasoline refined from oil, so a surge in crude passes quickly into prices. According to Stanley, "if oil prices are popping, you're going to get inflation flowing through it. The Fed is going to have to hike more than they want to hike." For debt-funded AI companies, that chain ends in a higher cost of capital.

AI Debt Cycle Revives the Dot-Com Squeeze on Unprofitable Firms

The AI debt cycle mirrors the financing pressure that took down dot-com companies in 2000, when higher borrowing costs weighed on firms that were not yet profitable. Rising rates also tend to signal stronger growth, which is why investors keep chasing returns in higher-beta, unprofitable AI names. Stanley separates spotting a bubble from timing its end, calling the ability to time a bubble popping "kind of a perilous quest". "Higher rates make for a more unfriendly corporate backdrop," he says, "and so you're going to see a lot of these companies with a lot of pain."
