#1Cerebras Explodes Onto Nasdaq in Biggest AI IPO of 2026
AI chipmaker Cerebras Systems raised $5.55 billion in its IPO, pricing at $185 per share before opening at $350 and closing up 68% at $311.07 — pushing its market cap to roughly $95 billion. Demand exceeded available shares by more than 20x, driven partly by OpenAI's $20 billion multi-year computing deal with the company. The offering is the biggest pure-play AI IPO to hit Wall Street and may crack open the 2026 IPO window for other AI startups.
