Nebius Group N.V. (NASDAQ:NBIS) stock fell on Monday due to intense competitive threats from Meta Platforms Inc. and high-volume insider selling.

The decline follows a broader risk-off trend impacting high-growth AI stocks. The Nasdaq is down 1.29% while the S&P 500 has shed 0.24%, and Technology is the weakest sector on the day.

Meta Enters AI Cloud Computing Market

The stock faced continuous downward pressure following reports that Meta is exploring an expansion into artificial intelligence computing services.

The potential expansion raised investor concerns that the technology giant could become a powerful new competitor in the fast-growing neocloud market, directly impacting Nebius.

Broader AI Market Pressures Mount

Last week, AI cloud service providers came under pressure after Samsung Electronics Co’s preliminary second-quarter results. Additionally, reports that DeepSeek is developing its own AI inference chips raised further concerns about the longevity of the broader compute buildout, accelerating the market-wide retreat from AI-related equities.

Top Executives Disclose Multi-Million-Dollar Insider Sales

Regulatory filings showed significant insider selling by senior Nebius executives, adding to negative investor sentiment on Monday.

CEO Arkadiy Volozh sold 46,627 shares at $235.45 apiece for approximately $10.98 million. Chief Technology Officer Danila Shtan sold 16,940 shares at the same price, totaling about $3.99 million, while Chief Infrastructure Officer Andrey Korolenko offloaded 33,870 shares for roughly $7.97 million.

Short Interest and Market Metrics Rise

Market data indicates that short interest in Nebius increased during the latest reporting period, rising from 50.93 million to 61.01 million shares. The shift placed 28.55% of the company’s publicly available shares short. Based on the recent average daily volume of 17.61 million shares, short sellers would require 3.46 days to close out their positions without triggering upward pressure on the stock.

Critical Levels To Watch For NBIS Stock

From a trend perspective, NBIS is still in a longer-term uptrend, trading 24.7% above its 100-day SMA ($171.47) and 56.8% above its 200-day SMA ($136.36). But the near-term picture has weakened, with the stock 12.7% below its 20-day SMA ($244.90) and 4.1% below its 50-day SMA ($222.96), a setup that often keeps rallies "sold into" until price can reclaim those averages. RSI is 45.54, which points to neutral momentum that’s cooling rather than oversold.

  • Key Resistance: $233.50 — a nearby rebound ceiling that also sits close to the 50-day/20-day EMA zone, where sellers often reappear
  • Key Support: $200.50 — a nearby floor just below current levels, where buyers may try to defend the pullback

NBIS Price Action: Nebius Group shares were down 2.10% at $212.59 at the time of publication on Monday, according to Benzinga Pro data.
