NVIDIA has partnered with SB Energy to secure an initial 4.25 IT-GW of AI capacity at the PORTS-Pike campus in Ohio, with OpenAI as the customer for the full 8 IT-GW site under a 20-year lease. The agreement features a $1.5B NVIDIA investment in SB Energy, credit support for the buildout, creation of tens of thousands of jobs and an $80M community benefits fund.
SB Energy, the SoftBank-backed developer of AI data centers, filed for a US IPO on Tuesday, reporting 66.4% revenue growth in the first half of 2026 and a $439 billion backlog while disclosing it has no operational facilities and is substantially dependent on OpenAI. The filing underscores the tight linkages among OpenAI, SoftBank, and Nvidia in the $500 billion Stargate project as the company seeks to broaden its customer base through acquisitions.
Anthropic's Claude service is down worldwide due to authentication system failures affecting multiple products. More than 1,500 reports appeared on Downdetector within minutes on September 29.
Anthropic's IPO prospectus warns its AI work could raise catastrophic risks to humanity while reporting a $42 billion net loss on $4.6 billion revenue. The filing also details plans for a founder-controlled LLC to retain 50.1 percent voting power post-IPO.
Anthropic introduced Claude Sonnet 5.5 at unchanged mid-tier rates of $2 per million input tokens and $10 per million output tokens. The model exceeded Opus 5.5 on Terminal-Bench 4.0 yet consumed more tokens at peak effort settings.
