Cerebras stock falls 42% from opening high as AI chip euphoria fades

Cerebras Systems shares have lost more than 42% since opening at $350 on debut, as the AI chipmaker's $95 billion valuation faces scrutiny over customer concentration and a history of losses.

Cerebras Systems shares have fallen 42% from their first-day opening price of $350, as the AI chipmaker's post-IPO rally gives way to concerns about its narrow customer base and path to profitability.

"The pre-IPO perpetual market on TradeXYZ provided remarkably accurate price discovery, trading within 2.8% of the eventual Nasdaq opening print," 0xResearch, a Blockworks newsletter, said in a review of the Cerebras listing.

The Sunnyvale, California-based company sold 30 million shares at $185, raising $5.6 billion in an IPO that was oversubscribed more than 20 times. Shares opened at $350 on May 14 and closed the first day at $311.07, giving Cerebras a market capitalization of about $95 billion. By June 5, the stock had fallen to $201, a loss of more than 42% from the opening print and 36% below the first-day close.

Cerebras takes a differentiated approach to AI computing, building giant single chips rather than clusters of smaller graphics processing units. The company claims its systems are up to 15 times faster than leading GPU-based solutions for many workloads. That approach won a $20 billion multiyear contract with OpenAI and partnerships with Amazon Web Services and Meta Platforms. Revenue surged from $24 million in 2022 to $510 million in 2025, but the company remains unprofitable and depends on a limited customer base for a large portion of its revenue.

A Different Architecture, A Familiar Valuation Debate

Cerebras' wafer-scale engine — a single silicon wafer etched as one massive processor — competes directly with Nvidia's GPU clusters, which dominate the AI training market. While Nvidia's H100 delivers 990 TFLOPS of FP16 performance using thousands of interconnected chips, Cerebras claims its approach eliminates the communication overhead between discrete processors. The company has not disclosed independent benchmark results for its latest chip, making direct comparisons with Nvidia's next-generation Blackwell architecture difficult to verify.

The IPO's pricing journey reflected intense demand. Cerebras initially set a range of $115 to $125 on May 4, raised it to $150 to $160, and ultimately priced at $185 — above the revised range. The first-day pop to $350 briefly valued the company at more than $100 billion before the sell-off began.

Pre-IPO Markets Nailed the Price

The TradeXYZ perpetual futures contract on Cerebras, launched May 1, traded at a volume-weighted average price just 1.2% above the eventual Nasdaq opening print in the final hour before listing, according to 0xResearch. The pre-IPO market processed over $200 million in notional volume at a median spread of 61.4 basis points — a functional level of liquidity for a contract with no public equity reference price. Underwriting banks monitored the Hyperliquid-based market during the IPO process, Pantera Capital said in a blog post.

Cathie Wood's ARK Investment Management purchased 105,616 shares across two ETFs on the first day of trading, worth about $32.8 million at the close, while trimming stakes in Taiwan Semiconductor Manufacturing Co. and Advanced Micro Devices.

For investors weighing whether the sell-off represents a buying opportunity or a value trap, the key questions center on Cerebras' ability to diversify its customer base beyond OpenAI and reach profitability. The company's revenue growth — from $24 million to $510 million in three years — demonstrates product-market fit, but its dependence on a single $20 billion contract creates concentration risk. Nvidia shares, trading at roughly 35 times forward earnings, have not been materially affected by Cerebras' public listing, suggesting the market views the challenger as years away from threatening the incumbent's dominance.
