Rumors from yesterday were around $3 billion.

They had raised a Series C investment recently. Historically that puts ownership of founders and employees at around 40%. Could be a lot higher for a hot AI company though.

Given two founders, AI company, Series C, and a $3bn purchase price they could each have netted around $750 million in a good scenario. Less if they cashed out in secondaries in previous rounds (which would have been smart). Fantastic outcome for them, obviously. This is the 0.001% scenario that founders dream about.
