Key Highlights

● Applied Digital plunged Friday, landing among the worst performers in an AI data-center selloff.

● No company-specific news was reported; the stock moved with debt-funded AI infrastructure names.

● CoreWeave was the focal point, with concerns over its debt of more than $50 billion.

● Meta Platforms reports Oct 21 and the Fed decides Oct 28.

Among the day's biggest losers

Applied Digital (NASDAQ:APLD), which builds and operates data centers for high-performance computing and artificial-intelligence workloads, plunged on Friday, according to market reports. The stock was listed among the worst performers at the close, alongside IREN (NASDAQ:IREN), Cipher Digital (NASDAQ:CIFR) and DigitalOcean (NYSE:DOCN), all of which tumbled in an AI data-center selloff.

No company-specific news was reported. The Russell 2000 stock moved with a group that bore the brunt of a shift in investor focus. As market commentary described it, investors moved from asking what AI can do to how it will be financed, and companies relying on borrowed money to build infrastructure were hit hardest.

Applied Digital was also heavily discussed online. It ranked tenth in retail-trader mentions on the day, with mention volume rising.

CoreWeave at the center

CoreWeave (NASDAQ:CRWV) was the focal point of the selloff. The AI cloud provider plunged amid concerns about its debt of more than $50 billion, according to market commentary. Its notes due 2032 have traded below 80 cents on the dollar since their June issue, and reports indicated that the cost to insure CoreWeave's debt hit a record. A research firm cut its price target on CoreWeave to $108 from $115.

Nvidia (NASDAQ:NVDA) CEO Jensen Huang came to CoreWeave's defense on Thursday in Stockholm. "CoreWeave's financial strength is improving every day," he said. Nebius Group (NASDAQ:NBIS), another leveraged AI-infrastructure provider, also plunged, per market data.

One market commentator framed the shift: "The AI group is now splitting between companies that can fund the buildout themselves and those that have to borrow." Reports indicated that more than $1 trillion had been erased from semiconductor and AI-related stocks over the week.

A broad retreat

The Russell 2000 fell 45.90 points to about 2,721 after opening higher, according to market data, while another report put the close at 2,719.57. The small-cap index lost about 85.6 points over the week.

Large caps were hit as well. The Nasdaq Composite dropped 572.99 points to 26,140.03, capping its worst week since June, while the S&P 500 lost 84.62 points to 7,659.44 and the Dow Jones Industrial Average slipped 175.28 points to 52,002.41. The PHLX Semiconductor Index fell to 11,137.29 with all 30 members lower. Investors rotated into energy, utilities, consumer staples and health care, and the Cboe Volatility Index climbed 3.53 points to 19.99.

Rates added to the strain on capital-hungry companies. The 10-year Treasury yield finished around 5.1, per market data, after topping 5.30 earlier in October, its highest since 2002.

Applied Digital Awaits Hyperscaler Spending Signals

The Federal Reserve's next decision is on Oct 28. Chair Kevin Warsh said at an IMF gathering in Bangkok, "I don't prejudge meetings." Futures still price a quarter-point hike by December. The personal consumption expenditures price index and the first estimate of third-quarter GDP follow on Oct 29.

The biggest near-term test for AI data-center stocks is next week's big tech earnings. One analyst said "upcoming Big Tech earnings will still need to demonstrate that the enormous investment in AI is translating." Meta Platforms (NASDAQ:META) reports after the close on Wednesday, Oct 21, and investors will look for signs that hyperscaler spending on data centers continues.
