The stock had closed at $276.17 the previous day. Trading activity exploded, with more than 30 million shares changing hands — approximately 85% higher than normal daily volume.The catalyst for this sharp downturn was a Bloomberg article detailing Meta Platforms’ intention to commercialize AI computing resources and models — including direct GPU capacity sales. This business model places Meta in direct competition with neocloud specialists such as Nebius and CoreWeave.CoreWeave similarly experienced a decline exceeding 6% following the same disclosure.The market reaction extends beyond simple competitive concerns. Meta currently ranks among the world’s largest purchasers of GPU computing power. A strategic pivot toward selling excess capacity rather than solely consuming it could fundamentally reshape supply dynamics across the entire industry.Neocloud companies including Nebius have benefited tremendously from surging AI infrastructure requirements. Wednesday’s market action demonstrated how rapidly investor confidence can evaporate when threatened by well-capitalized competitors.Robust Growth Metrics Clash With Valuation ConcernsThe stock decline contrasts sharply with Nebius’s operational performance. The company delivered $399 million in quarterly revenue — representing an extraordinary 684% year-over-year expansion. Management exceeded earnings projections by $0.54 per share, posting a loss of just $0.23 compared to the consensus estimate of a $0.77 loss.The organization’s customer acquisition pipeline has reached unprecedented levels, and underlying demand for AI infrastructure capabilities continues accelerating. However, several Wall Street analysts had previously cautioned that the stock’s valuation appeared overextended following its remarkable pre-earnings rally.NBIS currently trades above its 50-day moving average of $215.92 and significantly above its 200-day moving average of $142.48. Even after Wednesday’s correction, the stock maintains considerable premium to these technical benchmarks.With a price-to-earnings multiple of 73.93 and a market capitalization approaching $58 billion, valuation remains elevated. The stock’s beta coefficient of 4.03 underscores its extreme volatility — a characteristic vividly illustrated by Wednesday’s price action.Wall Street Perspectives and Executive Stock SalesThe analyst community maintains a generally favorable outlook despite divided opinions. Fifteen analysts currently cover the stock, with nine recommending Buy and six maintaining Hold ratings, resulting in a “Moderate Buy” consensus. The mean price target stands at $203.25.Bank of America established a $280 price objective with a Buy recommendation in early June. BNP Paribas Exane initiated research coverage in June with a Neutral stance and $255 target. Morgan Stanley maintains an Equal Weight rating alongside a $144 price target.Insider transaction patterns present a more cautious narrative.

The Chief Revenue Officer sold roughly $3 million on June 2nd, trimming his stake by 28.6%.Collectively, company insiders have liquidated more than $124 million in stock value during the past 90 days.Nevertheless, institutional investors have demonstrated confidence by expanding positions. Orbis Allan Gray, Fred Alger Management, and Morgan Stanley have all increased their shareholdings in recent reporting periods.Wall Street analysts project Nebius will report a full-year loss of $1.91 per share on average.The post Nebius (NBIS) Stock Plunges 17% on Meta’s Cloud Infrastructure Ambitions appeared first on Blockonomi.
