For years, megacap technology companies with fortress-like balance sheets could largely tune out the Federal Reserve, treating interest rate cycles as a secondary concern that hit smaller, less profitable rivals far harder. That era is ending. Artificial intelligence is turning once-cash-rich tech leaders into heavy borrowers racing to build out power-hungry data centers, making the sector newly and acutely sensitive to borrowing costs and monetary policy signals.
The shift was on full display this week as investors digested Federal Reserve Chairman Kevin Warsh’s first press conference, where the central bank left the door open to a rate hike later in 2026 amid persistent inflation concerns. The 10-year Treasury yield climbed near 4.45%, and tech stocks felt the pressure. For an industry long valued on future growth rather than current cash flows, higher rates now carry a more immediate sting.
“Tech investors are not as used to looking at rates,” Peter Boockvar, chief investment officer of One Point BFG Wealth Partners, said in an interview. “All of a sudden tech investors need to listen to what Kevin Warsh has to say, they need to start paying attention to what the inflation stats are and how the U.S. Treasury market responds to it.”

The reason is straightforward but profound: the hyperscalers are in the midst of an unprecedented capital expenditure arms race. Amazon, Alphabet, Microsoft, and Meta alone are projected to deploy a combined $750 billion this year on AI infrastructure — an 80% jump from 2025. Much of that spending is being financed through debt, turning companies that once generated mountains of free cash flow into more traditional, capital-intensive businesses.
From Cash Cows to Borrowers
Goldman Sachs recently highlighted that capital expenditure as a percentage of cash flow for big tech is at its highest level since the dot-com bubble era. The bank expects total tech capex this year to approach $920 billion, noting that Wall Street estimates have consistently proven “too conservative” in each of the past three years.
Amazon, forecasting roughly $200 billion in spending, is widely expected to post negative free cash flow. Other giants are similarly tapping debt markets aggressively. Nvidia, Oracle, Amazon, Alphabet, and Meta have each issued tens of billions in bonds recently. OpenAI’s CFO Sarah Friar has cited access to debt markets as one motivation for going public, while bankers for SpaceX, fresh off its record Nasdaq debut, are already preparing investors for a potential $20 billion bond offering.
“It’s underappreciated,” said Jeff Kilburg, CEO of KKM Financial. “There’s an insatiable demand for AI-related funding. Tech leadership is embracing debt. It’s the perfect recipe for these AI folks who feel comfortable in what they want to borrow, and spend.”
This borrowing surge changes how investors must assess the sector. Higher interest rates raise the cost of capital for these massive buildouts and increase the discount rate applied to future cash flows — the very metric that has long justified sky-high valuations for growth stocks.
A New Reality for Tech Valuations
For smaller tech companies, rate sensitivity has always been part of the game. Investors price them on distant profits, so when the “risk-free rate” rises, those future earnings become worth less today. Now the effect is moving upstream to the biggest names.
Jay Woods, chief market strategist at Freedom Capital Markets, cautions against painting the entire sector with one brush. Nvidia, for instance, remains in a strong cash position, with free cash flow surging past $48.5 billion in the latest quarter, up from $26.1 billion a year earlier.
“They still have a deep cash bench, so I don’t think it’s that big of a red flag,” Woods said about Nvidia. “It does give them flexibility.”
Even so, the broader trend is unmistakable. Tech giants are increasingly behaving like old-economy industrials — capital-intensive, reliant on both debt and equity markets, and vulnerable to swings in borrowing costs and commodity prices (especially energy for data centers).
Boockvar frames it as a fundamental evolution.
“Tech investors are learning what it’s like to be an investor in old-economy industrial businesses that are capital intensive. Free cash flow is volatile and access to both debt and equity markets are crucial in order to finance it all,” he said.
Issuing debt can be strategic, preserving liquidity for acquisitions or providing flexibility for long-term projects, but it also introduces new risks if rates keep climbing or credit conditions tighten.
What This Means for Markets and the AI Race
The implications extend beyond individual companies. As mega-cap tech becomes more rate-sensitive, the sector’s role as a market leader could introduce new volatility. Investors who once viewed big tech as a defensive growth haven may need to reassess in an environment where Fed decisions carry heavier weight.
This dynamic also raises questions about the sustainability of the AI buildout. If higher rates meaningfully increase financing costs, some projects could be delayed or scaled back, potentially slowing the pace of AI advancement. At the same time, the race for dominance may force companies to accept higher borrowing costs rather than cede ground to rivals.
Warsh’s signals this week, leaving the door open to hikes amid sticky inflation, served as an early test of this new reality. Tech stocks sold off, yields rose, and the message was that the days of big tech being largely insulated from monetary policy are over.
For an industry that has driven much of the market’s gains in recent years, this transition marks a new chapter. The AI boom is real, but its capital intensity is forcing even the largest players to confront economic fundamentals they could once largely ignore. As Peter Boockvar noted, tech investors now have an entirely new reason to pay close attention to the Federal Reserve — and that attention is unlikely to fade anytime soon.
