TL;DR: The AI stock selloff paused on Monday, October 19, 2026. Nasdaq 100 futures rose more than 1% before the US open, most Asian markets closed higher and Bitcoin climbed back to roughly $82,500-$83,000. Two things helped: China’s third-quarter growth beat forecasts at 4.5%, and oil fell after President Trump waived new sanctions on Russian energy. The questions behind last week’s rout, especially AI debt and CoreWeave’s credit stress, haven’t gone away, and this week’s earnings from Meta, Tesla and others will test the bounce.
Last week’s AI stock selloff was the worst stretch for US tech in months. According to CNBC’s live markets coverage, the S&P 500 lost nearly 2%, its biggest weekly drop since late June, and the Nasdaq fell 4.5%, ending a four-week winning streak. Here’s what caused the slide, what’s behind Monday’s rebound, why the credit market matters so much right now, and what to watch over the next few days.
What drove last week’s AI stock selloff
The selloff wasn’t about one bad headline. It was a mix of worries about how the AI build-out is being paid for, and whether revenue is growing fast enough to justify it.
The Anthropic revenue report
CNBC reported, citing people familiar with the matter, that Anthropic told investors its third-quarter revenue reached $16.8 billion, up from about $11.6 billion in the second quarter. That’s strong growth by any normal standard. But CNBC’s live blog noted that the figure “raised flags among investors about the pace of growth with the AI build-out.” Reuters separately reported that investors were tempering their expectations for Anthropic’s IPO valuation over a slowdown in revenue growth.
Debt behind the data center boom
The bigger issue was debt. Companies that borrow heavily to buy chips and build data centers came under pressure, and Reuters said chip and tech hardware stocks such as Dell fell sharply. Reuters also noted that the Philadelphia SE Semiconductor index had slumped about 12% in October, though it was still up 57% for the year. We’ve seen similar strains before, from OpenAI’s revenue gap and the Oracle selloff to the collapse of the Microsoft-Nscale UK data center deal.
The CoreWeave and AI credit angle
CoreWeave became the focus of the scare. CNBC says the neocloud company plunged more than 25% last week (25.21% by the close), its biggest one-week drop since November 2025, over concerns about its debt.
According to a CNBC report from October 15:
- CoreWeave has taken on more than $51 billion of debt and obligations to fund its AI infrastructure.
- The yield to maturity on its 9.75% bond due in 2031 reached 15.78%.
- The spread on its five-year credit default swaps (insurance against default) at one point topped 1,140 basis points. It last stood near 1,038, up 16% in a week and 164% from a year earlier.
- S&P Global Market Intelligence’s Gavan Nolan told CNBC that a spread of 1,000 basis points or more is generally a sign of credit distress.
CoreWeave’s side of the story matters too. CEO Mike Intrator wrote in a memo obtained by CNBC that the market “misunderstands and acts irrationally” at times, and that the company is “confident in our backlog which more than supports all of our debt obligations.” Deutsche Bank put that backlog at over $100 billion, about two-thirds of it with investment-grade customers such as Microsoft and Meta.
The worry spread beyond one company. Goldman Sachs traders wrote on Friday, as quoted by CNBC, that “AI Credit Spreads and hyperscalers specifically are at the widest levels of the year,” adding that “AI Capex has likely peaked and financing, sustainability, and returns on capital have become the debate.” CNBC also reported that Oracle’s five-year CDS spread rose about 10% in a week, to 282 basis points.

What’s driving Monday’s rebound
Early Monday, CNBC reported that Nasdaq 100 futures were up 1.16%, S&P 500 futures rose 0.58% and Dow futures gained 0.17%, or 87 points. CoreWeave was up 3% in premarket trading, and Intel rose about 4% after JPMorgan upgraded the stock to neutral from underweight.
China’s growth beat
Reuters reported that China’s economy grew 4.5% year on year in the third quarter, above the 4.4% economists had expected and faster than the 4.3% pace in the second quarter. Quarter on quarter, growth was 1.2%. CoinDesk added that retail sales rose 1.1%, more than double the 0.5% forecast. CNBC said exports drove much of the gain, with China’s monthly trade surplus hitting a record $133.5 billion.
Lower oil after the Russia waiver
Oil fell after President Trump suspended new duties on buyers of Russian energy, which traders read as a sign of more supply. CNBC reported Brent crude down 2.38% at $107.25 a barrel and US crude down 1.78% at $99.60. The October 16 White House order waives sanctions and duties under the new Graham Act. Prices are still high, with attacks on tankers in the Persian Gulf and Ukrainian strikes on Russian energy sites clouding supply.
Asia and Bitcoin
Per CNBC, South Korea’s Kospi closed up 1.76% and Australia’s S&P/ASX 200 gained 0.44%, while Japan’s Nikkei 225 bucked the trend and fell 0.62%. Europe was weaker, with the Stoxx 600 down 0.82%, as violent protests in France weighed on stocks there. In crypto, Investing.com said Bitcoin rose 1.3% to $82,783 by 2 a.m. ET, after two straight weekly losses, and CoinDesk had it around $83,000 in early European trading.
What to watch this week
CNBC says 70 S&P 500 companies report this week. These are the events most likely to decide whether the bounce holds:
| When (ET) | Event | Why it matters |
|---|---|---|
| Tuesday, Oct. 20 | General Motors (before the bell), Netflix and United Airlines (after the bell) | Consumer demand and the impact of high fuel costs, per CNBC |
| Wednesday, Oct. 21 | Meta and Tesla (after the bell) | Meta is the first hyperscaler to report; investors want proof that AI spending pays off |
| Wednesday, Oct. 21 | Lam Research and Texas Instruments | Reuters says these could signal broader chip demand |
| Thursday, Oct. 22 | Procter & Gamble and American Airlines (before the bell) | A read on non-tech sectors that held up last week |
| This week | SpaceX results | Reuters lists the newly public company among key reports |
| All week | CoreWeave bonds and CDS spreads | The clearest gauge of AI credit stress |
| All week | Oil prices and Fed rate bets | Reuters says hot inflation data lifted bets on a rate hike at the late-October Fed meeting |
Reuters cited Goldman Sachs estimates that five AI hyperscalers, Meta among them, are expected to lift combined capital spending to about $1.2 trillion next year. “One of the most important takeaways of earnings season is whether or not the profitability of the hyperscalers can grow faster than the pace of their capex,” BNY Wealth’s Kevin Shea told Reuters. Rates are the other pressure point. CoinDesk notes that the Fed raised rates by 25 basis points last month, and Reuters says most investors expect it to wait until December before raising them again.
The bottom line
Monday’s rebound is real but narrow. It came from outside the AI story, through China’s data and cheaper oil, not from any answer to the debt and returns questions that caused the AI stock selloff. Meta’s results on Wednesday and CoreWeave’s credit spreads are the two things most likely to show whether last week was a shakeout or the start of something longer.
