NVIDIA announced it would invest $1.5 billion in SB Energy. The investment was announced with plans for NVIDIA to secure capacity at SB Energy’s PORTS-Pike campus, where OpenAI would be the tenant.

OpenAI said it had closed its financing round with $122 billion in committed capital at a post-money valuation of $852 billion, naming NVIDIA, Amazon and SoftBank as anchor investors with continued participation from Microsoft. CNBC reported the total was up from the $110 billion OpenAI had announced in February and called it the largest private funding round in Silicon Valley history.

OpenAI announced a $110 billion financing round that included a $30 billion investment from NVIDIA. OpenAI put the round's pre-money valuation at $730 billion and identified Amazon and SoftBank as other major investors. It said NVIDIA would provide 3 gigawatts of dedicated inference capacity and 2 gigawatts of Vera Rubin training capacity.

OpenAI, Oracle, and SoftBank announced five new U.S. AI data-center sites under Stargate. The announcement identified the sites as Stargate projects.

OpenAI named SoftBank, OpenAI, Oracle, and MGX as the initial equity funders in Stargate. The announcement identified Oracle as one of the project’s initial funders.

OpenAI raised $6.6 billion in new funding at a $157 billion post-money valuation. Axios reported that Nvidia joined the round led by Thrive Capital.

Seventeen months after signing, the companies terminated the agreement, citing significant regulatory challenges, and Nvidia wrote off the $1.36 billion it had prepaid. Arm listed on Nasdaq in September 2023 at a $54 billion valuation; Nvidia kept a 20-year Arm architecture licence and went on to build its own Arm-based Grace CPUs.

The largest chip deal ever proposed would have put the architecture behind nearly every smartphone under the company that dominated AI accelerators, with SoftBank keeping under 10 percent of Nvidia. Huang promised to keep Arm's open licensing model and its Cambridge headquarters; customers including Qualcomm, Google and Microsoft objected within months.
