Sam Altman, chief executive of OpenAI, took the stand Wednesday in a California federal courtroom, facing a lawsuit filed by Elon Musk. The case, stemming from a rift that began when Musk invested $38 million in OpenAI’s early days, seeks to overturn the company’s for‑profit restructuring and strip Altman and co‑founder Greg Brockman of leadership roles. Testimony so far has included senior figures from Microsoft and former OpenAI insiders, underscoring the high‑stakes clash between two of the tech world’s most prominent AI pioneers. Read more

SpaceX has signed a lease with Anthropic for the full capacity of its Colossus 1 data center in Memphis, Tennessee. The early‑May 2026 deal gives Anthropic access to more than 220,000 Nvidia GPUs and over 300 megawatts of power, easing a near‑term compute crunch for the maker of Claude. SpaceX, which plans an IPO, turns idle infrastructure into revenue, while the arrangement underscores the growing importance of in‑house AI hardware as rivals such as xAI’s Grok scramble for resources.

The U.S. Commerce Department deleted a web page that described an agreement in which Microsoft, Google and Elon Musk's xAI would submit their most advanced AI models to government scientists for security testing before public release. The page, first posted on May 5, vanished Monday afternoon and now redirects to the Center for AI Standards and Innovation, the agency that runs the tests. Neither the department nor the Trump White House offered an explanation, and the three companies have not commented. The removal comes amid shifting federal AI policy and ongoing debate over giving the government pre‑release access to frontier AI systems. Read more

xAI has rolled out Grok Voice Mode for Apple CarPlay, letting drivers converse with Elon Musk’s outspoken AI assistant straight from the dashboard. The feature arrives with the latest Grok iPhone app update and can be launched manually through CarPlay, though it lacks a wake word and cannot control vehicle functions like climate or navigation. By moving beyond Tesla’s limited integration, the rollout opens Grok to millions of iPhone users and puts it in direct competition with other third‑party voice assistants on the platform. Read more

Elon Musk's SpaceX has signed a data‑center agreement that grants Anthropic access to more than 200,000 Nvidia GPUs at the Colossus 1 supercomputer in Tennessee. The partnership, announced after Musk previously accused Anthropic of stealing training data, will boost capacity for the company's Claude Pro and Claude Max services and includes plans to explore gigawatt‑scale orbital AI compute. Anthropic responded by doubling usage limits for several products and listing other data‑center deals with Amazon, Google and Microsoft. The deal has drawn criticism from the NAACP, which alleges environmental harm to Black communities near the Tennessee facility. Read more

Elon Musk's xAI and Anthropic announced Wednesday that the Claude-maker will purchase the entire 300‑megawatt compute capacity of xAI's Colossus 1 data center. The move instantly lifts Anthropic's usage limits and monetizes a key xAI asset, turning the startup from a consumer of AI power into a cloud‑service provider. Musk said the purchase frees up Colossus 1 as xAI shifts its training workloads to a newer facility, Colossus 2, and aligns with the company's broader push toward an IPO and a space‑based data‑center vision.
