AI Chip Selloff and Tech Borrowing Stoke Bond-Market Fears
The generative AI boom has driven demand for advanced processors and data centers, making Nvidia and Taiwan Semiconductor Manufacturing Co. central to the investment cycle. But the buildout extends well beyond servers, requiring substantial spending on power, cooling, networking and land. As major technology companies increasingly turn to debt markets to fund that infrastructure, concerns over AI investment are spreading from richly valued chip stocks to government bonds and the broader economic outlook.
U.S. chip shares fell sharply in the latest selloff, with Nvidia, TSMC and other AI-linked names coming under pressure as investors reassessed rising financing costs and the data-center boom’s less visible expenses. Heavy bond issuance by large technology companies could compete with U.S. Treasury supply for investor capital, helping keep Treasury yields elevated. Persistently high borrowing costs may, in turn, weigh on corporate investment and economic growth over the coming years.

The history behind this eventChip Rout Deepens as AI Financing Fears Mount Ahead of Fed
The AI boom has driven hyperscalers to spend hundreds of billions of dollars on data centers and semiconductors, powering a sharp rally in chip stocks while stretching valuations and balance sheets. Investors are now scrutinizing whether returns can justify the outlays. Nvidia’s role as both a supplier to OpenAI and a potential financier of its purchases has sharpened fears of “circular financing,” in which vendors help fund demand that supports their own revenue, leaving the sector more exposed if borrowing costs rise or AI spending slows.
On July 28, the Philadelphia Semiconductor Index fell 3.5% intraday, with Micron down 8.8%, Intel 4.6% and SanDisk 13%. Nvidia had dropped about 5% on July 27 after reports it could guarantee roughly $250 billion of financing for an OpenAI data-center project in Ohio and separately finance $350 billion of chip purchases. Bitcoin slid 3.1% to about $63,495. Traders assigned a 28% probability to a Federal Reserve rate increase on July 29, while Microsoft, Amazon, Meta and Apple were due to report earnings during the week.
