Anthropic AI News — Latest Updates, Tracker & Coverage

Anthropic ended April being priced as a long-dated electricity hedge. Google committed up to $40B at a $350B valuation with 5GW of Cloud capacity over five years; Amazon doubled-up earlier the same week with $25B and matching Trainium capacity. With $30B+ revenue run rate (1,400% YoY), an October IPO at $800B is now in play.

The other story this month: Mythos, a model held back under Project Glasswing because it can autonomously discover zero-days, was breached via a third-party vendor portal — containment failed at the procurement layer, not the model layer. AI Weekly tracks every Claude release, lab deal, and security disclosure.
