Cerebras Has Lost a Third of Its IPO Peak — Can $510 Million in Revenue Justify a $50 Billion Bet on AI Chips?

Shares of Cerebras Systems slid 7.1% to $220.05 on June 1, extending a punishing selloff that has now erased more than $30 billion in market value since the stock touched $386 on its May 14 debut day. The stock opened at $350 on IPO day — nearly double its $185 offering price — and briefly sent the company's market cap to almost $70 billion. Two weeks later, investors are asking whether the largest tech IPO of 2026 got ahead of itself.

• The Math Behind the Hype Still Doesn't Add Up for Many Investors. The stock's price-to-sales ratio — meaning how many dollars investors pay for every dollar of revenue — remains north of 100, with an enterprise value above $52 billion.

Cerebras posted $510 million in 2025 revenue (up 76% year-over-year) and swung to $237.8 million in net income from a $481.6 million loss the prior year. Those are impressive growth numbers, but at today's price investors are still paying roughly $100 for every $1 of trailing sales — a level that demands near-flawless execution for years.

• A Handful of Customers Carry the Entire Revenue Base. In its refreshed IPO filing, Cerebras disclosed that 24% of 2025 revenue came from UAE-based G42, down from 85% in 2024, but the Mohamed bin Zayed University of Artificial Intelligence in the UAE still accounted for 62% of last year's sales.

Morningstar flagged that "customer concentration would be another" key risk, "especially since OpenAI has made large chip deals and will need to continue to grow to justify such deals." If any single contract slips, the revenue picture changes dramatically.

• Big Contracts Provide a Floor — But Not a Guarantee. Cerebras holds a multi-year agreement to supply OpenAI with 750 megawatts of AI computing power, valued at over $10 billion.

Amazon Web Services also agreed in March to install Cerebras chips in its data centers. These deals give real revenue visibility, yet Morningstar analysts warn that "the greatest risk for Cerebras investors would be intense competition in AI inference, especially versus market leader Nvidia and its Groq business unit."

• Post-IPO Gravity Is Normal — But the Landing Zone Is Unclear. Cerebras has fallen more than 30% since topping out at $386.24 on IPO day.

If the company lands another major customer and grows into its valuation, the trajectory could surprise to the upside — but customer concentration is severe, and the valuation remains, in one analyst's words, "borderline euphoric." For shareholders, the next earnings report will be the first real test of whether the stock's premium price tag has any foundation in operating reality.
