Shares of NVIDIA tumbled nearly 5% on Monday, settling at $196.51 and wiping out roughly $250 billion in market capitalization in a single session — the stock's largest drop since February 2026. The trigger: a Wall Street Journal report that NVIDIA is in talks to provide roughly $250 billion in financing guarantees for OpenAI , a deal that forced investors to ask whether the world's most important chipmaker is quietly morphing into a lender to its own customers.

  • The Deal Is Enormous — and OpenAI Can't Fund It Alone. The guarantee would help OpenAI lease a 10-gigawatt campus in Piketon, Ohio, developed by SoftBank's SB Energy, with total project costs exceeding $500 billion including chips.

OpenAI lacks an investment-grade credit rating and is projected to lose approximately $14 billion in 2026 on around $25 billion in revenue.

NVIDIA's balance sheet would effectively stand in for that missing credit rating, letting lenders price the debt against the chipmaker's finances rather than the borrower's. In plain terms: if OpenAI can't pay, NVIDIA is on the hook.

  • A Separate $350 Billion Chip-Financing Package Makes the Loop Even Tighter. Beyond the lease guarantee, NVIDIA is considering $350 billion in financing for OpenAI's GPU purchases — a combined package totaling $600 billion that would be the largest single AI infrastructure project in history.

Critics argue the structure, in which OpenAI uses NVIDIA-backed funding to buy NVIDIA chips, risks overstating GPU demand and magnifying losses.

  • Credit Markets Are Already Flashing Warnings. NVIDIA's credit default swap spreads — essentially the cost of insuring against a debt default — widened by their largest single-day amount on record.

The sell-off also knocked NVIDIA from the top market-cap spot, ceding it back to Apple.

The Philadelphia Semiconductor Index fell 2.23% , and Asian chip stocks cratered, with Samsung down 13.4% and SK Hynix off 14.7%.

  • Bulls Say the Panic Is Overblown — for Now. The guarantee moves no cash unless OpenAI fails to pay, and as of July 27 the arrangement remains unsigned.

Some 85% of covering analysts still rate NVIDIA a Buy or Strong Buy, with an average price target near $303. But CEO Jensen Huang's dismissal of circular financing as "preposterous" rings hollower each time NVIDIA deepens its financial entanglement with unprofitable customers. The stock's next catalyst: earnings on August 25, where management will have to explain why selling chips now requires bankrolling the buyers, too.
