Cerebras Files Updated IPO Terms: $3.5bn Raise at $26.6bn Valuation

May 4, 2026 – 1:15 pm

Three days after suggesting it might target up to $4bn at $40bn, the AI chipmaker has marketed 28 million shares at $115-$125 each, lining the deal up with its February private valuation rather than above it.

Cerebras Systems was preparing to seek up to $4bn at a roughly $40bn valuation in its long-awaited initial public offering. On Monday, the company filed an updated prospectus that priced the deal more cautiously: 28 million shares at a marketed range of $115 to $125 each, raising as much as $3.5bn at the high end.

At that range, the implied valuation lands closer to $26.6bn, well below the figure circulating last week and roughly in line with the $23bn private mark Cerebras carried after its February Series H.

It is, by any reading, a more grounded number. Whether it is grounded enough is the question the order book will answer.

Per the updated prospectus filed on Monday, Cerebras intends to list on the Nasdaq Global Select Market under the ticker CBRS, with Morgan Stanley, Citigroup, Barclays and UBS Investment Bank as joint book-running managers.

The 28-million-share offering carries an underwriter option of an additional 4.2 million shares, which would lift gross proceeds by roughly $525m at the top of the range. CNBC notes that chief executive Andrew Feldman, the company’s co-founder, is not selling shares in the IPO; he will hold 10.3 million shares post-deal, worth as much as $1.28bn at the high end.

The financial profile underlying the offering is, by AI-hardware standards, well-developed. Cerebras’s most recent quarter showed revenue up roughly 76 per cent year-on-year to $510m, with $87.9m in net income.

The company’s Master Relationship Agreement with OpenAI, signed in January, promises up to 750 megawatts of inference capacity through 2028 in a contract Cerebras has previously valued at more than $20bn over its term. That deal, more than any single demonstration of wafer-scale technology, has anchored the IPO narrative since.

Why the valuation came down?

The shift from a possible $4bn raise at $40bn to a marketed $3.5bn at roughly $26.6bn is not, by IPO standards, dramatic. It is also not nothing. There are three plausible readings:

1. Execution: Filing at a wider range and a more sober valuation reduces the risk of an undersubscribed book on launch day, and it gives the deal room to price up if demand is strong. After two years in which AI hardware listings have priced below initial ranges as often as above, that discipline is sensible.

2. Market context: AI software multiples have been compressing through April, with Palantir down roughly 30 per cent year-to-date and Citi cutting price targets across the AI-platform space. While Cerebras is hardware rather than software, hardware listings have not been immune to that broader recalibration. Pricing inside the now-public reference points for memory and compute is again sensible.

3. Concentration risk: Public-market investors, in their diligence on the prospectus, will have noted that OpenAI is the dominant customer in the deal. The economics, if OpenAI executes as planned, are formidable. If OpenAI’s compute demand recalibrates, even modestly, the impact on Cerebras’s valuation could be significant.
