Cerebras IPO Frenzy Could Crack Open the AI Listing Floodgates

Axios, the New York Times, Barron’s, and FOX Business contributed to this report.

Cerebras did not just make a strong debut on Wall Street. It detonated onto the market.

The AI chipmaker opened at $350 a share Thursday, nearly 90% above its IPO price, then briefly surged to $385 before ending the day at $311. That kind of first-day chaos instantly reignited talk of a broader IPO comeback, especially for AI companies that have spent years hiding comfortably in private markets.

The scale of the jump caught even bullish investors off guard. Cerebras had initially aimed to price shares between $115 and $125. Just four months ago, it sold stock privately at $89 a share during its Series H round.

Now venture firms that backed the company early are sitting on enormous paper gains.

Benchmark, one of Cerebras’ biggest supporters long before AI chips became the hottest trade on the planet, invested about $268 million over the years. By Thursday’s close, that stake was worth roughly $5.5 billion.

That is a staggering payoff for investors who backed a chip company built around an unfashionable idea at the time: massive memory-heavy processors designed for AI workloads.

The IPO also sent a message across Silicon Valley. Investors are clearly still hungry for AI exposure, even with stretched valuations, power concerns and questions about how sustainable the frenzy really is.

Cerebras has some obvious vulnerabilities. A big chunk of its revenue comes from a concentrated group of customers. Its expansion plans will require enormous amounts of electricity at a time when US policymakers are increasingly uneasy about the strain data centers place on the power grid.

None of that slowed demand this week.

The bigger risk may come next, when insiders begin selling shares.

Unlike many IPOs that lock shareholders up for six months, Cerebras structured its lockup schedule in waves. About 30 million additional shares become eligible for trading almost immediately, with more unlocks arriving after quarterly earnings and continuing through October.

That creates the possibility of constant selling pressure hanging over the stock.

Wall Street has seen how quickly momentum can reverse. Figma’s volatile trading after its own blockbuster debut remains fresh in investors’ minds. If Cerebras starts sliding hard after the initial excitement fades, retail traders may become a lot more cautious about jumping into the next AI listing.

Still, the debut has already changed the mood around the IPO market.

For years, highly valued startups stayed private longer because funding was easy to raise. AI companies especially had little incentive to test public markets. Cerebras may have just shifted that calculation.

Now investors are watching who moves next. SpaceX is looming over the calendar, and companies tied to AI infrastructure, data centers and energy are suddenly looking at a market that appears wide awake again.

After a long drought, Wall Street finally smells momentum.
