NEW YORK, May 15, 2026, 04:06 EDT
Cerebras Systems Inc. Class A Common Stock (CBRS) pushed higher in early Friday premarket action, building on a blistering first-day run that saw the AI chipmaker finish its Nasdaq debut 68% above the IPO price.
This one’s drawing attention: Cerebras is giving investors their first chance this year to bet on an AI hardware name that isn’t Nvidia. Early Friday, StockAnalysis.com had CBRS at $328.80 as of 4:04 a.m. EDT, a 5.7% bump over Thursday’s close at $311.07. The shares kicked off at $350 and reached as high as $386.34 during their debut.
Cerebras priced its IPO at $185 per share, moving 30 million Class A shares in the offering—its debut on the public markets. The company expects to wrap up the transaction on Friday. Underwriters also picked up a 30-day window for an extra 4.5 million shares.
Cerebras pulled in $5.55 billion from its IPO, landing a fully diluted valuation of $56.43 billion, according to Reuters. That figure takes into account all potential shares, including options and restricted stock. With this debut, it’s the biggest U.S. market listing of 2026 to date.
Cerebras markets AI systems that use its wafer-scale engine—a processor fashioned from an entire silicon wafer, not just a chip. According to the company, this architecture is designed to accelerate AI inference, the process of running trained models, especially as organizations shift focus from developing models to deploying them widely.
That drops Cerebras straight into a market dominated by Nvidia, still the go-to name for GPUs. According to Reuters, Cerebras has locked in Amazon and OpenAI as clients, offering public investors a more direct shot at AI infrastructure demand outside the usual biggest listed chip players.
“In Silicon Valley we understand just how big AI will be,” Cerebras CEO Andrew Feldman told Reuters. As these models grow more advanced, Feldman said, “the amount we use them will explode.” Reuters
The debate over valuation kicked in almost right after the shares started trading. Nicholas Smith, senior research analyst at Renaissance Capital, told Reuters the $185 IPO price looked “reasonable” if you’re using projected 2028 sales and EBITDA—earnings before interest, taxes, depreciation and amortization—as benchmarks. “At the current price, it is quite high even out to 2028,” he said.

Prediction-market traders landed not far from what equity markets suggested. On Polymarket, the Cerebras IPO closing-market-cap contract settled the $60 billion to $70 billion range at a full 100% after Thursday’s close, with $370,708 traded. Elsewhere on the platform, odds still favored SpaceX by a wide margin—87%—to claim the top IPO market cap by the end of 2026. Anthropic trailed at 8%. Traders, in short, aren’t betting that Cerebras will hang onto its early lead as the year unfolds.
Supply risk hangs over the stock, too. According to a May 14 SEC reoffer prospectus, up to 6,808,018 Class A shares could hit the market as Class B holders convert and look to cash out. Those shares might be offered at market value, tied to market prices over a period, or hammered out through negotiation. The same filing flagged a high degree of risk for anyone considering the securities.
At this point, CBRS offers investors a fresh, straightforward way to play AI chips. The real question isn’t demand for the IPO—investors showed up. What comes next: can Cerebras actually justify the early trading price that public buyers stamped on it?
