Trading of Cerebras Systems ($CBRS) officially began on the Nasdaq on Thursday, May 14, 2026. The stock closed its first trading day at $311.07. With the IPO price set at $185.00, the stock surged an impressive +68.14% on day one.
Leading up to the IPO, reports suggested that the expected offering price range had already been raised from $115–125 to $150–160, while the number of shares offered was increased from 28 million to 30 million shares. In the end, the IPO price was raised even further to $185 per share, with 30 million shares issued, resulting in a massive $5.55 billion offering. In addition, the lead underwriters were reportedly granted a 4.5 million share over-allotment (greenshoe) option.
Although CBRS pulled back slightly on Friday, May 15, the stock still closed at a very strong $279.72. It seems fair to say that this “prelude” to the 2026 IPO festival was a huge success.
Next comes the first true main event of the IPO festival: SpaceX. For now, reports suggest that the IPO price could be finalized on Thursday, June 11, with trading potentially beginning on Friday, June 12.
And after that, Anthropic and OpenAI are expected to follow. For many investors, 2026 may already be shaping up to be a year where there simply isn’t enough capital to keep up with the scale of these AI IPOs.
