Notes settle as selling builds

Cipher Digital (NASDAQ:CIFR), the company formerly known as Cipher Mining, fell sharply on Friday, the day its zero-coupon convertible senior notes settled. The notes, priced earlier in the week, are intended to fund the company's Barber Lake data center, according to market reports. A related headline cited an $850 million offering, though the underlying report did not give a size.

The stock's decline grew as the day went on. Market reports showed the shares modestly lower at $9.75 in the morning, and a later roundup of closing movers listed Cipher among the day's biggest AI data-center decliners, alongside Applied Digital (NASDAQ:APLD), IREN (NASDAQ:IREN) and DigitalOcean (NYSE:DOCN).

Convertible notes can be exchanged for stock under certain conditions, and settlement marks the point at which the company receives the proceeds. The Barber Lake project is part of Cipher's shift from bitcoin mining toward hosting high-performance computing for artificial-intelligence customers.

The AI-financing scare

Friday's selling centered on how the artificial-intelligence build-out will be paid for. Investors moved from asking what AI can do to how it will be financed, and debt-funded infrastructure names were hit hardest, according to market commentary. Reports indicated that more than $1 trillion was erased from semiconductor and AI-related stocks over the week.

CoreWeave (NASDAQ:CRWV) was the focal point. The AI cloud provider plunged amid concerns about its debt of more than $50 billion, and reports noted that the cost to insure its debt hit a record. Nvidia (NASDAQ:NVDA) CEO Jensen Huang defended CoreWeave on Thursday, saying, "CoreWeave's financial strength is improving every day."

One market commentator said, "The AI group is now splitting between companies that can fund the buildout themselves and those that have to borrow." The commentator added, "That is a change in character, and it's another reason the leaders no longer look like a safe haven."

Crypto pressure added to the strain. MSCI (NYSE:MSCI)'s new rules on non-operating companies weighed on bitcoin-linked stocks, and peers Riot Platforms (NASDAQ:RIOT) and TeraWulf (NASDAQ:WULF) also fell, according to market reports.

Small caps lose ground

The Russell 2000 fell 45.90 points to about 2,721, according to market data, after opening higher. Another data point put the close at 2,719.57. The S&P 500 lost 84.62 points to 7,659.44, the Nasdaq Composite fell 572.99 points to 26,140.03 and the Dow Jones Industrial Average slipped 175.28 points to 52,002.41. Energy, utilities and consumer staples gained as investors rotated into defensive areas, and the Cboe Volatility Index climbed 3.53 points to 19.99.

Cipher Digital Barber Lake Progress Ahead

The Federal Reserve's Oct 28 decision is also in view. Chair Kevin Warsh said, "I don't prejudge meetings," and futures still price roughly one quarter-point hike by December, which matters for companies financing expansion with debt.

More broadly, AI-infrastructure stocks will take cues from next week's big tech earnings: Meta Platforms (NASDAQ:META) reports after the close on Wednesday, Oct 21, offering a read on data-center spending plans. One senior market analyst said "upcoming Big Tech earnings will still need to demonstrate that the enormous investment in AI is translating." For Cipher, the focus will be on progress at Barber Lake now that the financing has closed.
