Nebius rises after AI hedge fund Situational Awareness discloses 5.6% stake

Nebius jumped 12% in premarket trading Thursday after Situational Awareness, the hedge fund run by former OpenAI researcher Leopold Aschenbrenner, disclosed a major stake in the AI cloud company.

According to its 13G filed Wednesday, the fund reported owning 12.4 million Class A shares of Nebius, representing a 5.6% stake worth ~$2.6 billion as of Wednesday’s closing price. The position didn’t appear in the fund’s most recent 13F filing — which covered holdings as of March 31 and included other neocloud companies such as CoreWeave and IREN — suggesting the Nebius stake was added sometime after the first quarter.

The disclosure puts Situational Awareness among Nebius’ largest disclosed institutional shareholders, at least based on the latest available ownership filings, which show BlackRock as the largest institutional holder as of March 31, with 4.5% of shares outstanding.

One of the “neocloud” stocks, Nebius has gained traction recently after securing large cloud contracts with Microsoft and Meta, as well as an equity investment from Nvidia and an energy partnership with Bloom. Shares are up 165% this year and a whopping 475% over the past 12 months.

Founded in 2024 by Aschenbrenner — and named after his widely read essay on artificial superintelligence — Situational Awareness has built its portfolio around the physical infrastructure AI runs on, from chips and data centers to power and compute. Per its 13F filings, the fund’s reported portfolio value climbed to $13.7 billion as of the first quarter, up nearly 2.5x from $5.5 billion at the end of 2025.

SpaceX gets a wave of bullish ratings from Wall Street analysts

SpaceX received more than a dozen positive analyst calls on Tuesday — including from major Wall Street banks — as they initiate coverage on Elon Musk’s space and AI company.

SpaceX went public on June 12 at a $2.2 trillion valuation, the largest debut in history. While the company hasn’t yet posted a profit, it seems to have convinced Wall Street that it will get there and grow its valuation on the way.

Of the at least 17 analysts that gave a rating on Tuesday, all but one gave it a “buy” or “outperform” rating. MoffettNathanson was "neutral."

The ratings come as SpaceX joined the Nasdaq 100 index, a benchmark tech-heavy basket of companies that underpins millions of portfolios. The inclusion adds built-in demand for the stock from index funds and ETFs.

Still, SpaceX fell more than 5% on Tuesday amid a broader sell-off, and is currently effectively flat from its opening price of $150 a share.
