> but I suspect there’s a more important factor here: I think they’ve finally found product-market fit

Ahhh the classic startup term that's definition is nebulous. But also, since when does any definition of product/market fit mean a product is profitable? And profitable in what sense? Unit economics? Overall company?

Oh I'm absolutely taking advantage of the fact that "product-market fit" has a bit of a nebulous meaning here.

It's a great hook to build an article around. My core point is more that April 2026 was the point when Anthropic and OpenAI finally appeared to have figured out a credible business model.
