A week of landmark moves: a near-trillion-dollar IPO filing, the most ambitious federal AI bill ever drafted, a reinvented ChatGPT memory system, and the largest IPO roadshow in history.
Anthropic Confidentially Files S-1 at $965 Billion Valuation
Anthropic submitted a confidential draft S-1 registration statement to the SEC on June 1, following a $65 billion Series H that pushed its post-money valuation to $965 billion — overtaking OpenAI in private-market value for the first time. The company’s revenue run-rate hit approximately $47 billion in May 2026, up roughly 5x year-over-year. A particular detail from the filing caught analyst attention: Anthropic is paying SpaceX $1.25 billion per month through May 2029 for compute — $15 billion per year to a single infrastructure vendor. Ahead of the filing, co-founder Daniela Amodei told TechCrunch she was unconcerned about doubts over AI’s returns, pointing to Claude’s enterprise traction as validation.
Congress Drops 269-Page Bipartisan AI Bill
Representatives Jay Obernolte (R-CA) and Lori Trahan (D-MA) released a 269-page discussion draft of the Great American Artificial Intelligence Act on June 4. Its most consequential provision: a three-year federal preemption of state AI laws, which would freeze Colorado’s Consumer AI Protection Act (due June 30) and similar statutes before they take effect. Companies with over $500M in revenue would be required to publish public AI governance frameworks and report critical safety incidents. Labor unions, including the AFL-CIO, rejected the draft outright, calling it a giveaway to the industry; tech industry groups broadly praised it. It remains a discussion draft, not yet formally introduced.
ChatGPT Dreaming V3 Rethinks How AI Remembers You
OpenAI began rolling out Dreaming V3, its most significant memory architecture upgrade since ChatGPT’s launch, to Plus and Pro users in the US on June 4. Unlike the previous system — which required users to explicitly prompt ChatGPT to remember something — Dreaming V3 runs a background synthesis process after conversations end, automatically cataloguing preferences, ongoing projects, and time-sensitive context, and pruning stale facts. OpenAI reports a roughly 5x reduction in compute requirements, making the feature viable for free-tier users in coming weeks. Privacy researchers have already noted that a February 2026 arXiv study found 96% of ChatGPT memories were created unilaterally by the system, flagging potential compliance friction with EU AI Act transparency rules taking effect in August.
SpaceX IPO Roadshow Targets Record $75 Billion Raise
SpaceX launched its investor roadshow on June 4, with pricing set for June 11 and trading on Nasdaq under the ticker SPCX opening June 12. The company disclosed $18.7 billion in 2025 revenue in its public S-1 filed May 20, following its all-stock merger with xAI completed in February. If the offering prices near its $75 billion target, it would surpass Saudi Aramco’s 2019 listing as the largest IPO in history. Goldman Sachs is leading a 21-bank syndicate, with 30% of the float allocated directly to retail investors through Robinhood, Fidelity, and Schwab — three times the typical retail allocation for a mega-cap offering.
Arizona Utility Proposes 45% Power Surcharge for AI Data Centers
Arizona Public Service, the state’s largest electricity utility, proposed a 45% electricity-rate increase targeted specifically at data centers, citing grid expansion costs driven by AI infrastructure buildout. The proposal, reported by the Wall Street Journal, would be among the largest utility-rate increases ever directed at a single industry sector. With AI data centers consuming power at densities that outpace utility planning cycles, similar proposals are expected in Texas and Virginia. The development adds another dimension to the cost-of-compute story unfolding across the industry.
What to watch: The SpaceX IPO pricing on June 11 will set the tone for both the Anthropic and OpenAI listings expected later this year — and Colorado’s AI Act clock is ticking with just 24 days to compliance.
