Nebius Group (NBIS) fell 11.4% in mid-day trading on Wednesday, wiping out the prior session’s gains after investors reconsidered the company’s aggressive spending plans and rising insider selling.
The stock had rallied Tuesday following two bullish announcements: a new asset-light partnership model for AI data centers and a $1 billion-plus compute deal with Reflection AI running through 2029. But the enthusiasm didn’t last.
NBIS opened Wednesday unable to hold above the $190 level — a psychologically important mark — and selling accelerated from there. The move fits a familiar “sell the news” pattern that has played out in AI infrastructure names multiple times this year.
At the center of investor concern is Nebius’s updated 2026 capital expenditure guidance of $20 billion to $25 billion. That’s a large number, and Wall Street wants to know when it turns into cash.
Much of the new capacity isn’t expected to generate meaningful revenue until the first half of 2027. The market is increasingly asking for clearer evidence of cash conversion, not just a growing contract backlog.
That concern is compounded by negative free cash flow and reliance on a small number of large contracts — factors that leave little margin for error if growth disappoints or funding costs rise.
Regulatory filings have shown heavy insider selling over recent weeks. The CEO, CTO, and Chief Infrastructure Officer have collectively sold tens of millions of dollars in stock, totaling more than $140 million in insider transactions over the past 90 days.
That kind of selling, even if planned in advance, tends to shake investor confidence — particularly when a stock is already under pressure.
The broader sector isn’t helping either. CoreWeave (CRWV) fell 6.15% on the same day. Reports that Meta (META) plans to monetize its own excess AI computing capacity have rattled neocloud names repeatedly since early July, with each recovery attempt meeting fresh selling.
The Nasdaq fell around 1% on Wednesday, creating an unfavorable backdrop for high-multiple growth names. The S&P 500 was down 0.34%, while the Dow held essentially flat — confirming the pain is concentrated in tech.
Even after Wednesday’s drop, NBIS trades at a premium to its neocloud peers. The stock’s 52-week low sits at $49, and year-to-date it remains up roughly 138% despite the pullback.
Nebius does carry some positives: fast-growing AI revenues, improving margins in its core business, and a solid cash position. The company’s current market cap stands at $48.84 billion.
