Nebius Signs $17.4 Billion AI Infrastructure Deal With Microsoft

/in /tarafından

Nebius Group (NBIS.O) announced on Monday a five-year agreement with Microsoft (MSFT.O) to provide GPU infrastructure capacity, a deal valued at $17.4 billion that could expand to $19.4 billion if additional services are acquired. The news sent Nebius shares surging more than 47% in after-hours trading.

The partnership highlights the escalating demand for high-performance AI compute as tech giants race to secure infrastructure for training and running advanced models. Under the deal, Microsoft will gain access to Nebius’ dedicated GPU infrastructure from a new Vineland, New Jersey data center starting later this year.

Nebius specializes in offering AI cloud services powered by Nvidia GPUs, combining computing, storage, management tools, and in-house designed hardware to support AI developers. CEO Arkady Volozh said the deal is not only financially significant but also positions Nebius for accelerated AI cloud growth from 2026 onwards.

Microsoft already stands as the largest customer of CoreWeave (CRWV.O), another AI infrastructure provider. The Nebius agreement suggests the company is broadening its supply chain to mitigate risks as hyperscaler demand grows.

Amsterdam-based Nebius was formed after the split of Russian tech giant Yandex, and has been expanding rapidly into the U.S. and European AI infrastructure markets.

Hedge Funds Double Down on Big Tech Amid AI Boom

/in /tarafından

Top Wall Street hedge funds, including Bridgewater Associates, Tiger Global Management, and Discovery Capital, increased their exposure to Big Tech stocks in the second quarter, capitalizing on a generational surge in artificial intelligence.

Funds reduced their holdings in lagging sectors such as aerospace, defense, consumer, and retail, returning to momentum investing as tech stocks staged a strong comeback. The S&P 500 (.SPX) is up 10% this year, largely driven by the largest technology companies, which make up nearly a third of the index’s market capitalization.

Outside tech, hedge funds like Lone Pine, Discovery, and Soros Fund Management also added positions in UnitedHealth Group (UNH.N), while Berkshire Hathaway unveiled new stakes. UnitedHealth shares are down 46% this year amid rising costs, a DOJ probe, a cyberattack, and the shooting of a former executive.

Quarterly 13F filings revealed these key hedge fund moves:

BRIDGEWATER ASSOCIATES:

  • Added significantly to Nvidia (NVDA.O), Alphabet (GOOGL.O), and Microsoft (MSFT.O).

  • Nvidia stake more than doubled to 7.23 million shares ($1.14B).

  • Alphabet and Microsoft increased by 84.1% and 111.9%, respectively.

  • Added Broadcom (+102.7%) and Palo Alto Networks (+117%).

DISCOVERY CAPITAL:

  • Doubled stake in America Movil (AMXB.MX) to 2.65 million shares ($95M).

  • More than doubled Meta Platforms (META.O) holdings and took a new position in Nvidia-backed CoreWeave (CRWV.O).

  • Increased UnitedHealth stake by 13%.

TIGER GLOBAL MANAGEMENT:

  • Bought more shares in the “Magnificent Seven”: Amazon (AMZN.O), Alphabet, Nvidia, Microsoft, and Meta.

  • Added ~4M Amazon shares, ending June with 10M shares ($2.34B).

  • Increased stakes in smaller AI-related companies such as Lam Research (LRCX.O).

COATUE MANAGEMENT:

  • Added new positions in Arm Holdings and Oracle (ORCL.N), worth ~$750M and $843M.

  • Increased holdings in Nvidia-backed CoreWeave to 3.39M shares ($2.9B).

LONE PINE CAPITAL:

  • Took a new position in UnitedHealth, buying 1.69M shares worth ~$528M.

These moves illustrate a clear pivot toward technology and AI-driven growth opportunities by major hedge funds in the wake of market volatility and tariff concerns earlier this year.

CoreWeave Shares Fall Despite Strong AI Demand as Losses Mount

/in /tarafından

Shares of CoreWeave, the Nvidia-backed AI infrastructure firm, dropped 11% after the company reported a larger-than-expected loss for Q2. Operating expenses surged nearly fourfold to $1.19 billion, highlighting tension between rapid revenue growth and rising financial strain.

Analysts expressed concern over CoreWeave’s heavy reliance on key customers, such as OpenAI, and questioned its ability to grow profitably given widening losses, high capital needs, and deteriorating debt coverage. The company, which went public in March, had about $8 billion in debt last year and planned to use roughly $1 billion of IPO proceeds for debt repayment.

With the IPO lock-up period expiring soon, analysts expect volatility as insiders can sell shares for the first time. CoreWeave operates 33 AI data centers in the U.S. and Europe, providing access to Nvidia GPUs. Despite losses, surging demand helped the firm beat quarterly revenue estimates, and its stock has nearly tripled since its IPO.
