October 26 was dominated by capital markets meeting the AI buildout: Anthropic’s S-1 kicked off a landmark IPO process while Broadcom, Wall Street banks, Meta, and SpaceX unveiled tens of billions in new equity and lease financing for chips and data centers. On the product side, OpenAI shipped GPT-6.1 Terra as a cost-efficient agent and computer-use model, and separately claimed major formal-science results with a more cautious academic release process. NVIDIA tightened its alliance with Meta around the Muse agent stack, and U.S. states moved toward implementation as Colorado closed public comment on ADMT and chatbot rules ahead of a January 2027 effective date. Watch next for Anthropic’s IPO pricing, closure of the SpaceX and Broadcom financing structures, and independent verification of OpenAI’s scientific claims.
