Good Friday, NOLA. May 29th is massive: Anthropic just raised $65B at a $965B valuation, eclipsing OpenAI, and released Claude Opus 4.8 with Dynamic Workflows for Claude Code. The market is consolidating around two players, and the practical reality of AI costs is hitting enterprises hard. Here's what matters.

The Big Story: Anthropic's Total Victory

Anthropic raises $65B in Series H at $965B post-money valuation

Anthropic just became the world's most valuable AI company, surpassing OpenAI. The more striking detail: their run-rate revenue hit $47B annually — basically, they're printing money. This isn't vaporware. Adoption has been accelerating since their Series G in February, and the market is clearly betting on them to be the dominant platform.

Reality Checks: The Cost Problem Gets Real

AI sticker shock hits corporate America

Enterprises spent billions on AI tooling this year and are only now asking: what did we actually get? Token costs are climbing, integration nightmares abound, and the promised productivity gains aren't materializing at scale. Microsoft's own data suggests hiring people is cheaper than running AI agents for some tasks. This won't kill the industry, but it's forcing a maturation moment.

The Longer View

Sam Altman and Dario Amodei are walking back AI jobs apocalypse predictions

Both CEOs have quietly backed away from earlier doomsaying about AI eliminating most jobs. Reality has a way of catching up with hype. The actual story is messier: some roles shift, some disappear, some new ones emerge. Less dramatic, more true.

Anthropic's run-rate revenue hits $47 billion

Simon Willison's take: the real story isn't the funding round — it's that Anthropic's annual revenue run-rate is now nearly $50 billion. That's not a venture business anymore; that's a mature, profitable platform. The market has decided.
