AI Debt Panic Wipes 27% Off CoreWeave as Fear Gauge Jumps Past 22

Investors dumped artificial intelligence stocks this week, and the damage landed hardest on companies that borrowed heavily to build the data centers powering the AI boom. CoreWeave, a cloud computing company that rents out AI infrastructure, saw its shares plunge 27.5% from the prior Friday's close to 52-week lows on Thursday morning before rebounding 17%, leaving equity traders dazed by the swing [1]. The tech-heavy Nasdaq fell 2% and posted its worst week since June as the selloff spread across major U.S. stock averages [3].

The trouble traces back to a corner of the debt market that stock investors often overlook. CoreWeave's bond yields and credit default swaps — insurance-like contracts that protect lenders if a borrower fails to pay — have surged, meaning debt investors are demanding higher returns and paying more for protection against a default [2]. Those swap costs have reached "distress" territory, a term for prices that typically signal lenders expect real trouble [10].

The pressure point matters beyond one company. CoreWeave carries significant debt, making it especially sensitive to rising interest rates, and many AI firms depend on borrowing to fund expensive data centers and high-performance chips [11]. U.S. stocks dropped as investors grew worried that AI profits will not arrive fast enough to cover the rising credit costs of CoreWeave and other aspiring hyperscalers — companies building massive data centers to rent out AI computing power [14].

Wall Street cannot agree on CoreWeave, and the selloff is pulling neocloud stocks lower while widening the valuation spread between AI leaders OpenAI and Anthropic [5][7]. Concerns about the financial health of the AI industry are growing again, putting pressure on chip stocks like Nvidia, the leading maker of chips that power AI systems [15].

The nervousness showed up in Wall Street's main measure of market fear. The Cboe Volatility Index, known as the VIX, climbed above 22 on Monday for the first time since April, and traders are betting the index will climb even higher [8]. Analysts described the episode as a "dress rehearsal" for what a full market correction might look like, showing how quickly confidence can fade when growth expectations slip [9]. The damage is limited for now, but markets have priced in years of AI gains, and any sign of delay can trigger sharp losses [9].
