DOJ Files Formal Complaint in Intervention Against Colorado AI Law

The U.S. Department of Justice filed a formal Complaint in Intervention on May 5, 2026, in xAI Corp v. Weiser, escalating the federal government's opposition to Colorado's SB 24-205 (the Colorado AI Act). The filing goes beyond the DOJ's earlier April 24 Statement of Interest, making the United States a formal party to the case. The DOJ argues that Colorado's algorithmic discrimination provisions violate the Equal Protection Clause and conflict with federal AI policy. Separately, a federal judge on April 27 paused enforcement of SB 24-205 pending further proceedings.

Shivon Zilis Testifies in Musk v. Altman Trial

Shivon Zilis, former OpenAI board member and the mother of four of Elon Musk's children, testified for hours on May 6, 2026, in the ongoing Musk v. Altman trial in Oakland. Zilis pushed back on OpenAI's characterization of her relationship with Musk as a secret allegiance, testifying that her relationship with Musk did not influence her duties as a board member. She confirmed that Musk had offered her the opportunity to use his sperm for conception. Zilis left the OpenAI board in 2023 after Musk started xAI. Her testimony came on the same day that former OpenAI CTO Mira Murati testified that Sam Altman "sowed chaos and distrust" among senior leadership.

Anthropic Signs Compute Deal With SpaceX

Anthropic announced on May 7, 2026 that it has signed an agreement with SpaceX to access all of the compute capacity at Colossus 1, one of the world's largest AI supercomputers. The deal provides Anthropic with over 300 MW of capacity and more than 220,000 Nvidia GPUs, substantially expanding the company's AI inference capabilities. In conjunction with the deal, Anthropic doubled Claude Code's five-hour rate limits for paid plans and removed peak-hours reductions for Pro and Max plans. The partnership comes amid Anthropic's ongoing dispute with the U.S. government over a supply-chain risk designation, and raises questions about the competitive dynamics between Musk's xAI/SpaceX and Anthropic, which has positioned itself as an AI safety-focused alternative.
