Cerebras Just Pulled Off the Biggest IPO Of 2026 So Far. History Says This Happens Next. - The Motley Fool

Cerebras Systems (CBRS 10.08%) just pulled off the biggest U.S. tech initial public offering (IPO) since Snowflake made its debut in 2020. The artificial intelligence (AI) chipmaker priced its shares at $185 on Wednesday evening, above its already-raised range of $150 to $160. The deal raised $5.55 billion and valued the company at about $56.4 billion on a fully diluted basis. Shares opened at $350 on the Nasdaq Thursday morning -- nearly double the IPO price. And sure enough, shares soared, reaching highs of $385 before closing at about $311 on its first day of trading. By any measure, it was a blockbuster debut. So what happens next? It's tempting to extrapolate from an IPO like this. But history offers some sobering lessons for investors hoping to ride that early enthusiasm higher.
