Anthropic has signed a cloud-computing deal worth about $35 billion with Lambda, the Nvidia-backed AI cloud provider, according to the Wall Street Journal, with Reuters carrying the report the same day. The WSJ reports that Nvidia holds the lease on the Texas data centre involved. Neither Anthropic nor Lambda has published the agreement on its own newsroom, and the WSJ account is attributed to a person familiar rather than to either company. Lambda separately closed a $926m senior secured term loan B facility on 27 August 2026 to fund GPU deployment for an investment-grade customer, which it did announce itself. This record is kept STRICTLY DISTINCT from the separate $35bn Anthropic CHIP FINANCING reported by Bloomberg on 9 June 2026, which concerned Google backstopping lease payments across five data centres - the identical headline figure makes the two easy to conflate and they are different events.

SSI and NVIDIA announced a long-term strategic partnership under which NVIDIA made an equity investment in SSI and gave it access to the next-generation NVIDIA Vera Rubin platform, allowing SSI to increase its compute by an order of magnitude. The two will also collaborate on the technical advancement of NVIDIA's current and future compute platforms, drawing on SSI's research. NVIDIA stated it entered the partnership after obtaining rare access to SSI's closely guarded research. Jensen Huang cited Sutskever's foundational contributions beginning with AlexNet; Sutskever said SSI has 'research that is worthy of scaling up' and described the Vera Rubin commitment as a 'big bet'. Neither primary source disclosed a figure — Reuters reported, citing an unnamed source, that the stake is approximately USD 5bn. That amount is NOT confirmed by either party and is recorded here as a report, not a fact. SSI's own updates page datelines the agreement 26 July 2026; both companies announced it publicly on 27 July 2026. SSI remains private and pre-product after roughly two years in stealth.

NVIDIA launched the Open Secure AI Alliance on Jul 27, 2026 with 27-37 founding members including Microsoft, SpaceX, Palantir, Cisco, IBM, Dell, CrowdStrike, Palo Alto Networks, Red Hat, Adobe, Hugging Face and the Linux Foundation, to develop and share open tools for securing AI systems. It follows a Hugging Face security incident and reflects an industry push to keep open-source AI viable for cyber defense. Notably absent: OpenAI and Anthropic.
