The $965 billion number is a distraction. Here’s what actually matters.

Last week, Anthropic raised $65 billion and saw its valuation approach a trillion dollars. Every business publication on the planet covered the number. Almost none of them covered the insight.

The insight came from Simon Willison, posting on May 27 — one day before the funding closed — and it’s worth more to your business than any valuation figure: enterprise AI has found product-market fit. Not “gaining traction.” Not “showing promise.” Fit. The kind where customers stop subscribing and start paying by the token because they’re consuming so much that the subscription ceiling became a constraint on their business.
