Cerebras raises $5.5B, kicking off 2026’s IPO season with a bang

Cerebras raised $5.5 billion in its IPO on Thursday, pricing shares at $185 Wednesday evening, way higher than its range ($115 to $125, later raised to $150-$160), even as it increased the size of the offering to 30 million shares. And pre-market trading indicates that shares are going to open with a giant pop, as retail investors bid up the price to grab them. (We’ll update this story after trading begins.)
