Cerebras went public last week with a strong debut that gave early investors roughly 76% gains, lifting the company's valuation to $991 million. The IPO attracted attention across the AI chip sector, with investors now reassessing the valuations of private competitors like Fractile.

Frédéric Razzouk, Fractile's founder, reportedly made around 76% on his Cerebras position during the IPO run. Fractile had previously raised $608 million, while Bitwise Capital led its Series B at a $2.4 billion valuation and raised €689 million in 2023, showing serious capital flowing into AI chipmakers.

The IPO results signal robust market demand for AI infrastructure and put pressure on private chip startups to justify their valuations. How the broader market prices Fractile and peers in coming rounds will hinge on whether Cerebras's post-IPO performance holds up.
