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.

Broadcom Projects Strong AI Growth for Fiscal 2026 With $10B Customer Win

/in /tarafından

Broadcom (AVGO.O) forecast a sharp improvement in artificial intelligence revenue for fiscal 2026 after securing more than $10 billion in AI infrastructure orders from a newly signed customer, CEO Hock Tan announced Thursday. The news boosted shares by 4% in after-hours trading, as investors cheered both the order and Tan’s commitment to remain at the helm for at least another five years.

Earlier this year, Tan hinted at four potential new partners exploring custom chip development with Broadcom. One has now placed a firm order, officially joining its roster of clients. While Broadcom did not disclose the name, analysts see the deal as another sign of cloud giants seeking alternatives to Nvidia’s dominant but costly GPUs.

Broadcom has positioned itself as a key enabler of generative AI, designing custom silicon to help hyperscalers overcome performance bottlenecks. “Custom offerings for cloud giants are well-positioned as Big Tech races to push model training and inference forward,” said Emarketer analyst Jacob Bourne, noting that while Nvidia remains the default choice, bespoke chips offer niche performance advantages.

The company’s AI revenue grew 63% to $5.2 billion in the third quarter ended August 3 and is projected to rise to $6.2 billion in Q4. Broadcom has also expanded its portfolio with new networking products, including the Tomahawk Ultra and next-generation Jericho chips, both aimed at accelerating AI computing workloads.

Despite booming AI demand, Tan acknowledged softness in the company’s non-AI semiconductor units, particularly in enterprise networking and service storage. Even so, Broadcom guided for fourth-quarter revenue of about $17.4 billion, above Wall Street’s estimate of $17.01 billion.

Broadcom shares have gained nearly 82% since April, extending a threefold surge over the past two years, while Nvidia stock is up 27% in 2025.

Equinix Signs Multiple Advanced Nuclear Deals to Power Data Centers

/in /tarafından

Equinix (EQIX.O), a leading data center developer and operator, announced on Thursday that it has entered into multiple advanced nuclear electricity deals, including power purchase agreements for fission energy and preorders for microreactors to support its operations.

The energy-intensive nature of data centers, especially with the growing adoption of technologies like generative artificial intelligence, has driven demand for large-scale electricity, raising concerns over power supply shortages. Equinix’s agreements aim to secure long-term electricity solutions rather than short-term fixes, according to Raouf Abdel, the company’s executive vice president of global operations.

In the U.S., Equinix plans to procure 500 megawatts of power from Oklo’s next-generation nuclear fission reactors and preordered 20 transportable microreactors from Radiant Nuclear. In Europe, the company has deals with ULC-Energy and Stellaria to eventually source power from next-generation nuclear developers. Equinix has also signed advanced fuel cell agreements with Bloom Energy, based in Silicon Valley.

These initiatives align with the U.S. Department of Energy’s pilot program for high-tech test nuclear reactors, which aims to have three projects operational within a year. The deals with advanced nuclear providers are expected to supply more than 1 gigawatt of electricity to Equinix’s data centers globally.
