The $4.8 Billion Day: Why Nebius Traders Fled While Its Backers Doubled Down

AI infrastructure stock Nebius drops 15% amid sector sell-off, even as Nvidia's 9.3% stake and a $27B Meta deal underscore strong fundamentals.

A single trading session erased nearly 15% from Nebius’s market value, yet the company’s fundamental story has arguably never been stronger. On Friday, the stock closed at €165.20 in Frankfurt and $187.77 on the Nasdaq, shedding 14.99% and 15.02% respectively. The move wiped out most of the gains from earlier in the week, when Nvidia’s disclosed stake had propelled the shares more than 18% higher.

The sell-off wasn’t triggered by bad news from Nebius itself. Instead, a sector-wide risk aversion gripped AI infrastructure names, dragging down peers like CoreWeave and IREN alongside it. Moody’s added to the unease by warning that surging capital expenditure across Big Tech could pressure credit quality for cloud and AI providers, pegging industry-wide capex at roughly $785 billion for 2026 and projecting a rise to nearly $1 trillion the following year. Bond investors, meanwhile, demanded higher yields on Meta’s planned $12 billion debt issuance for a Texas data center — a signal that the capital markets are scrutinizing the financing behind the AI boom more closely.

Trading volumes at Nebius exploded to around $4.77 billion, making it the most heavily traded stock of the day and representing a more than 40% increase from the prior session.

The Nvidia Anchor and the Meta Mega-Deal

The paradox is that the very developments that should underpin the stock’s valuation came in the same week as the rout. Nvidia disclosed via a Schedule 13G filing that it holds roughly 22.3 million shares, or 9.3% of Nebius — an investment worth around $2 billion, though the bulk consists of warrants exercisable only from September 11, 2026. That’s more than a passive bet; it’s a seal of approval for Nebius’s specialized GPU infrastructure.

Even more consequential is a capacity agreement with Meta that could reach $27 billion over five years, adding to an existing $17 billion Microsoft contract. Combined, the company’s bookings now reportedly exceed $40 billion. Nebius plans to deploy more than five gigawatts of Nvidia systems by 2030 and recently validated the first Vera Rubin NVL72 rack in Finland.

To fund this expansion, the company secured a $775 million secured credit facility from MUFG on July 20, priced at SOFR plus 2.50 percentage points and maturing in October 2030. Crucially, the loan is backed by GPU infrastructure and contracted cash flows, allowing Nebius to finance its aggressive buildout without immediately resorting to dilutive equity. The company also unveiled a new asset-light partnership model designed to reduce the capital intensity of future data center projects — a relevant consideration given an expected $20 billion to $25 billion in capital expenditure for 2026.

Insider Sales and the Technical Picture

Adding to Friday’s pressure were insider transactions that some market participants may have misread. CEO Arkadiy Volozh and the CFO sold a combined 668,405 shares worth roughly $140 million over the past three months, with Volozh alone offloading $10.98 million in stock. These appear to be automated RSU sales to cover tax obligations rather than discretionary bets against the company, but in a volatile tape, perception matters more than intent.

The technicals paint a mixed picture. The 14-day relative strength index sits at 42.6 — neutral territory, not yet oversold. The stock has lost about a quarter of its value over the past 30 days, yet it remains 36.31% above its 200-day moving average and has gained 124.76% year to date. At €165.20, it trades 16.88% below its 50-day average of €198.75, suggesting the selling has been more than routine profit-taking.

Short interest stands at roughly 24% of the free float, a level that keeps the stock vulnerable to squeezes but also reflects deep skepticism among a significant cohort of traders.

The Valuation Debate

Analyst opinions remain sharply divided. Northland recently raised its price target to $410, and Baird upgraded the stock to Strong Buy. The broader consensus is more cautious, with targets clustering between $222 and $259 and ratings mostly at “Moderate Buy.” The valuation itself is a sticking point: depending on the metric, the price-to-earnings ratio ranges from 60 to over 100, far above the sector average of roughly 27.

Revenue growth, however, is unmistakable. First-quarter sales hit $399 million, up roughly 684% year-over-year, and full-year 2026 revenue is projected to climb 537%. Nebius reported net income of $29 million for 2025, though the path to sustainable profitability remains uneven.

The company is also positioning itself as a cost-efficient alternative to hyperscale clouds. Through its “Token Factory” — integrating Eigen AI, acquired in May 2026 for $643 million — Nebius aims to cut inference costs for open-source models by up to 70%. Custom liquid cooling and high-density racks reduce server power consumption by roughly 20%, giving it a hardware edge alongside its software story.

Consolidation or Correction?

With a market capitalization of €48.7 billion and a share price 36.70% below its 52-week high, the central question is whether the order book secured by Meta and Nvidia justifies the current valuation — or whether a more significant repricing is underway. The annualized 30-day volatility of 119.30% leaves no room for the faint-hearted.

For now, the fundamental thesis rests on two pillars: Nvidia as an anchor shareholder and the Meta deal as a revenue backstop. As long as both remain intact, the story holds — even if the daily swings suggest otherwise.
