NEW YORK, January 1, 2026, 16:35 ET — Market closed
- Nebius shares were last down about 1.7% at $83.71 in the last U.S. session of 2025.
- U.S. stock markets are closed Thursday for New Year’s Day and are set to reopen Friday, Jan. 2.
- A Form 144 filing disclosed a planned sale of 500 Class A shares by director Kira Radinsky, with the transaction slated for Jan. 2.
Nebius Group N.V. (NBIS) shares slipped into the year-end close, last down about 1.7% at $83.71, as traders headed into a holiday shutdown and weighed a newly disclosed planned insider sale.
The move matters because there is no fresh price discovery today, with U.S. exchanges shut for New Year’s Day. The next read on risk appetite for high-beta AI infrastructure names comes when trading resumes on Friday, Jan. 2.
Nebius is a Netherlands-based infrastructure company focused on cloud and tooling for AI workloads, according to Reuters’ company description. It has drawn investor attention in 2025 after signing a multi-year agreement to supply AI infrastructure to Microsoft.
The stock’s pullback came alongside a softer tape to close out 2025. Wall Street’s major indexes ended the final session lower, and thin holiday trading can amplify late-year profit-taking, “especially when liquidity was low,” said Giuseppe Sette, co-founder and president of Reflexivity. Reuters
In the most recent company-specific disclosure, a Form 144 dated Dec. 30 showed director Kira Radinsky planned to sell 500 Class A ordinary shares with an aggregate market value of about $43,795 through Citigroup Global Markets, with the transaction listed for Jan. 2.
Form 144 is a required notice when insiders intend to sell stock under SEC Rule 144, which governs resales of certain shares held by affiliates or obtained through restricted transactions. The notice signals intent, but it does not confirm a sale has occurred.
The filing described the transaction as “sell-to-cover,” a common term for sales used to cover taxes or withholding tied to equity compensation. That framing can temper concerns about discretionary selling, but traders still watch for additional filings or heavier selling into the open.
Before Friday’s reopening, investors are likely to focus on whether the shares hold the recent trading range after the holiday lull breaks. The stock traded between roughly $82.94 and $86.41 in the last session, levels that can act as near-term support and resistance when volume returns.
Macro sensitivity remains a backdrop for 2026 positioning, with investors looking at how persistent AI spending will be and whether financing conditions stay supportive for capital-heavy buildouts. Reuters’ market outlook coverage has flagged AI investment and the rate path as key swing factors for U.S. equities in 2026.
On the company calendar, investors are also watching for the timing of Nebius’ next quarterly update and any guidance on capacity buildout and capital needs. The company’s investor site shows it reported fourth-quarter 2024 results on Feb. 20 last year, offering a reference point for when 2025 full-year results could arrive.
For Nebius, the near-term question is whether enthusiasm around contracted AI infrastructure demand can offset concerns about the costs of building and powering data centers. Trading on Jan. 2 will be the first test of 2026 risk appetite for the name after the holiday break.
