Welcome to the AI Daily Briefing for Friday, May 29th, 2026. I'm Bob, and here's what happened in AI over the last 24 hours.

Anthropic just closed the biggest funding round in history — a sixty-five billion dollar Series H at a staggering nine hundred and sixty-five billion dollar valuation. That surpasses OpenAI's reported eight hundred fifty-two billion. The round was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia. Notably, three memory chip giants — Samsung, SK Hynix, and Micron — joined as strategic infrastructure partners. There's speculation Samsung may manufacture custom Anthropic AI chips. The company hit a forty-seven billion dollar annual revenue run rate, up from fourteen billion in February. KPMG announced it's deploying Claude to all two hundred seventy-six thousand global employees.

In the coding AI space, Cognition — the company behind Devin — raised a billion dollars at a twenty-five billion dollar valuation. Devin hit four hundred ninety-two million in annual recurring revenue. A striking stat: roughly eighty-nine percent of Cognition's own code is now written by Devin. Customers include Mercedes-Benz, NASA, and Goldman Sachs.

Anthropic also released Claude Opus 4.8. The update includes user-adjustable thinking depth, a two-and-a-half times faster mode, and stronger coding performance. The model now shows improved epistemic humility — essentially admitting when it's uncertain. Anthropic's next model, code-named Mythos, is expected in early June.

On the regulation front, Illinois just passed America's strongest AI safety bill, SB 315. It requires frontier AI developers to undergo mandatory annual independent third-party audits and report safety incidents within seventy-two hours. OpenAI and Anthropic supported the bill. It now heads to the governor's desk for a signature.

In open source, Hao AI Lab at UCSD released Dreamverse — a real-time open-source video generation system. You can generate, edit, and rewrite scenes with natural language, live. Thirty seconds of ten-eighty-p video renders in about seven seconds on a single NVIDIA B200 GPU.

Other notable rounds: Anduril raised five billion at sixty-one billion valuation, Isomorphic Labs raised two point one billion for AI drug discovery, and European AI companies raised three point three billion in May alone.

That's your general AI briefing. See you tomorrow.
