Nebius: Insider Sales Test a 495% Rally as Institutions and Analysts Double Down
Veröffentlicht: 04.06.2026 um 15:03 Uhr, Redaktion boerse-global.de
Nebius shares took a 5% hit on Thursday, sliding to €205.75 amid a broad technology sell-off driven by Middle East tensions and interest-rate uncertainty. The pullback came just a day after the Amsterdam-based AI cloud specialist presented at the Bank of America Global Technology Conference — and right as a flurry of insider transactions raised eyebrows. Yet beneath the surface, the numbers tell a story that has drawn some of Wall Street's most aggressive bets and a $2.6 billion vote of confidence from a high-profile hedge fund.
The company's first-quarter 2026 results provide the raw material for that optimism. Revenue hit $399 million, an eye-popping 684% surge from the prior year and a 75% jump sequentially, with roughly 98% of sales coming from AI infrastructure and cloud services. Chief Business Officer Roman Chernin told the BoFA conference that current capacity is entirely sold out, and the balance sheet holds $9.3 billion — much of it from customer prepayments. To sustain that momentum, Nebius is planning capital expenditures of between $20 billion and $25 billion for data centers, power capacity, and new AI factories in the U.S., including a 310-megawatt facility already under construction in Finland.
The institutional response has been emphatic. Leopold Aschenbrenner's Situational Awareness fund, run by a former OpenAI researcher, disclosed a passive 5.6% stake of roughly 12.41 million Class A shares, a position valued at around $2.6 billion as of early June. It marks the fund's single largest holding and a clear endorsement of Nebius's vertically integrated strategy in high-performance computing. Meanwhile, Geode Capital Management bulked up its position by nearly 1,100% in the fourth quarter, ending with about 2.05 million shares.
Should investors sell immediately? Or is it worth buying Nebius?
Yet insiders have been moving in the opposite direction. CFO Dado del Maria Sanchez Alonso sold approximately 1,500 shares on June 2, and Chief Revenue Officer Marc Boroditsky unloaded nearly 10,800 shares the same day, both at $276.20 apiece. Boroditsky's sale on June 3 was described as an automated transaction for tax optimization — typically pre-planned, but still notable given the stock's dizzying run. Earlier in May, insider Andrey Korolenko had sold 500,000 shares at an average price of $203.24. The pattern has fueled debate over whether these disposals reflect mere profit-taking after a staggering rally or a deeper concern about near-term upside.
Analyst opinions are sharply divided, adding another layer of uncertainty. DA Davidson downgraded the stock from Buy to Neutral in mid-May while keeping a $250 price target. Citizens JMP, by contrast, lifted its target from $175 to $270 over the same period, reaffirming a Market Outperform rating. The most bullish call comes from Citigroup, which raised its price objective to $287 — the highest on Wall Street — citing the revenue explosion and the scale of Nebius's infrastructure buildout.
The stock's valuation, however, tests every historical boundary. It trades at roughly 65 times annualized sales, compared with a sector median of about four times. That premium implies investors are pricing in a continuation of hypergrowth — some forecasts see full-year 2026 revenue hitting $3.4 billion. Technical indicators flash caution: the relative strength index sits at 72, signaling overbought conditions, and the stock trades well above its 20-day exponential moving average of $210 and its 50-day EMA of $175. Daily swings routinely exceed $23, underscoring the volatility lurking beneath a 169% year-to-date gain and a near-495% advance over the past twelve months.
The current price stands roughly 15% below the 52-week high of €242.95 set on June 2. Whether the insider sales are a canary or just cash-outs after a historic run may become clearer once Nebius reports its next batch of capacity figures and order intake. For now, the company's execution — and its ability to turn a $25 billion capex plan into sustained revenue growth — remains the ultimate test.
