Nebius Group (NBIS) shares are under heavy selling pressure today, falling below their 20-day moving average, after a Bloomberg report revealed that its largest customer, Meta Platforms (META), is building an internal cloud infrastructure business called Meta Compute. This initiative directly threatens Nebius's core business of providing bare-metal GPU capacity to AI developers.
Meta Compute aims to sell excess AI computing power and hosted models to external developers, placing the social media giant in direct competition with specialized neocloud providers like Nebius. The news is particularly damaging because Nebius recently secured a multi-year AI infrastructure partnership with Meta valued at up to $27 billion. Investors now fear that Meta is transitioning from a key customer to a formidable rival.
Despite today's decline, NBIS shares remain up approximately 150% year-to-date, reflecting the stock's volatile but strong performance. However, the Meta Compute announcement could reshape the competitive landscape for AI infrastructure. By commercializing its surplus GPU clusters, Meta could flood the market with low-cost, high-performance compute capacity that Nebius cannot match without sacrificing margins. Additionally, Meta's privileged access to customer workloads may allow it to bundle compute with its own AI models and developer tools, creating a closed-loop ecosystem that further marginalizes external providers.
The structural shift raises concerns that Nebius's long-term growth curve may flatten sooner than expected. Wall Street is also wary of the stock's stretched valuation—NBIS trades at roughly 125 times sales, leaving little room for setbacks. Insider selling has been aggressive, with 17 sell transactions recorded since the start of 2026 and zero purchases. Short interest has climbed to about 24%, making the stock vulnerable to sentiment shifts.
The consensus rating on NBIS remains a "Moderate Buy," but the mean price target of approximately $237 is in line with current trading levels, suggesting limited upside. The broader AI infrastructure boom has faced headwinds, including local opposition blocking data center projects and rising competition from hyperscalers. For context, local opposition has blocked $130 billion in data center projects, threatening the sector's expansion. Meanwhile, Micron's 700% surge highlights the market's appetite for AI-related plays, but Nebius's reliance on a single dominant customer now appears to be a significant risk.
Investors should monitor whether Meta Compute gains traction and how Nebius adapts its strategy. The company's ability to diversify its customer base and maintain margins will be critical in the coming quarters. For now, the market is pricing in a more competitive and uncertain future for NBIS.
