Cerebras Systems shares trade about 52% below their post-IPO peak, yet the stock still costs roughly 145 times next year's expected earnings. The decline followed no bad quarter — Cerebras raised its full-year outlook the same month shares fell. A $25.4 billion backlog, much of it tied to an OpenAI computing deal, gives the growth story visibility, but the profits the price assumes are still years away.
Cerebras Systems trades around $184, about 52% below the $386.34 peak shares hit on their first day of trading in May. That peak came a day after the company priced its IPO at $185 and raised $6.4 billion. Even after that drop, the stock still costs about 145 times the earnings analysts expect the company to generate next year.
The sell-off did not follow a stumble. There was no guidance cut, no lost customer, no bad quarter. Instead, shares dropped double digits the day after Cerebras' mid-August update, arguably the company's strongest yet, in which management raised its outlook for the year.
Growth hasn't been the problem
In that update, Cerebras reported core revenue of $209.9 million, up 103% year over year, with core gross margin improving to 41% and core operating margin to negative 16%. Management also raised its full-year outlook to a range of $880 million to $890 million in core revenue, up from a prior range of $855 million to $865 million.
The cloud business is driving that growth. Cloud and other services revenue climbed from $33 million a year earlier to $126 million in Q2 2026, up 281% year over year. That segment now supplies 70% of reported revenue, up from about a third a year ago.
The valuation did the falling
What changed is what buyers will pay for that growth. Analysts expect Cerebras to earn about $1.25 per share next year, and at around $184 the stock costs about 145 times that estimate. Measured against the same figure, May's $386.34 peak worked out to about 310 times next year's expected earnings.
The valuation, not the business, appears to have taken the hit: buyers are still paying largely for profits that remain mostly forecast rather than delivered.
A backlog that hasn't turned into earnings yet
The bull case rests on contracts already signed. Cerebras ended June with $25.4 billion in remaining performance obligations, much of it tied to a single agreement. Under that deal, OpenAI committed to purchase 750 megawatts of AI computing capacity. The company expects about $5.6 billion of that backlog, or 22% of it, to convert to revenue over the 24 months ending June 30, 2028.
Chief financial officer Bob Komin said in the company's Q2 2026 earnings release: "We have made rapid progress in key areas required to deliver exceptional growth". Revenue could well triple next year, as the contracts support it, but revenue isn't earnings.
Cerebras still ran a core operating loss last quarter even with sales doubling, and most of the backlog converts only after mid-2028. Cut in half is not the same as cheap: at 145 times next year's earnings, the stock still assumes years of rapid growth and a smooth swing to profitability, leaving little room for the timing to slip.
