Cerebras IPO Soars – Is Nvidia’s Real AI Challenger Finally Here?

On May 14, 2026, Cerebras Systems listed on Nasdaq with an opening price of $350 per share, quickly climbing to $385—a 108% increase that triggered a circuit breaker and pushed the intraday market value beyond $800 billion. The stock closed at $311.07, a 68.15% rise, leaving the company with a market cap of $669 billion, the strongest U.S. IPO of the year.

Cerebras distinguishes itself by fabricating a "world’s largest chip" using an entire 12‑inch wafer as a single die, called the wafer‑scale engine (WSE). The chip contains 1.2 trillion transistors, giving it a core area that dwarfs traditional AI accelerators and delivering raw compute power aimed at top‑tier AI workloads for customers such as OpenAI and AWS.

The company secured a $10 billion contract with OpenAI early in the year to provide 750 MW of AI compute, making Cerebras a core supplier for OpenAI’s training infrastructure. In March, AWS selected the WSE‑3 chip to expand its data‑center capacity, effectively granting Cerebras long‑term contracts with two of the world’s largest cloud and AI providers.

Financially, Cerebras reported 2025 revenue of $510 million, a 76% year‑over‑year increase. More importantly, the firm turned profitable, improving earnings per share from a $9.90 loss in 2024 to a $1.38 profit in 2025.

The IPO raised $5.55 billion, with an over‑allotment option that could bring total proceeds to $6.38 billion—the largest U.S. technology IPO since Uber’s 2019 offering. Cerebras plans to invest the entire amount in further chip development and production capacity, directly targeting Nvidia’s market share.

Overall, Cerebras’ successful listing and its unique wafer‑scale architecture demonstrate that the AI chip market is no longer a monopoly of Nvidia; the industry now faces a well‑funded, technically differentiated rival poised to reshape high‑performance AI training.
