Cerebras Systems just pulled off the first blockbuster tech IPO of 2026. The Nvidia challenger raised $5.5 billion on Thursday, then watched its stock pop 108% on the first day of trading, according to TechCrunch AI. Shares priced at $185 the night before, opened at $385, and settled at $311 by close, handing the company a $66 billion valuation.
This is a stunning reversal for a company that looked dead in the water a year ago.
What happened
TechCrunch AI reports the IPO blew past every expectation set during the roadshow:
- Initial range: $115 to $125
- Raised range: $150 to $160
- Final pricing: $185
- Offering size bumped to 30 million shares
- Opened at $385 (up 108%)
- After-hours: still climbing
Even at the $185 IPO price, Cerebras entered day one at a $56.4 billion fully diluted valuation. CEO Andrew Feldman’s stake was worth nearly $1.9 billion at the offering price. CTO Sean Lie clocked in around $1 billion. Both numbers ballooned as retail investors piled in.
Why this almost didn’t happen
Cerebras first filed to go public in 2024. The deal got buried under a CFIUS review tied to a heavy investment from Abu Dhabi’s Group 42, which at the time accounted for almost all of Cerebras’ revenue. Investors weren’t impressed by the customer concentration. The IPO plans got shelved.
Then the financials shifted. In April, the company reported $510 million in 2025 revenue, up 76% year-over-year, with a customer base that finally looked diversified. Net income swung from a loss of nearly half a billion to a $237.8 million profit. That changed the conversation completely.
Why it matters for the AI industry
Cerebras builds a giant wafer-scale chip designed from scratch for AI workloads. The company has positioned itself as a serious supplier of inference compute, the ongoing processing that runs every prompt sent to a deployed model. Inference is where the real, recurring AI spend is heading.
The customer list now includes OpenAI (through what TechCrunch AI calls a “complicated circular-deal relationship”), G42, Saudi Arabia’s Mohamed bin Zayed University of Artificial Intelligence, and Amazon Web Services.
What stands out here is the signal. Public markets are hungry for a credible Nvidia alternative, and they’re willing to pay a premium for one. A $66 billion valuation for a company doing $510 million in revenue tells you investors are pricing in massive growth in inference demand, not just current performance.
What to watch next
Three things to track in the coming quarters:
- Whether Cerebras can keep diversifying revenue away from G42 dependency
- How the OpenAI relationship evolves, given the circular financing dynamics
- Whether other AI hardware players (Groq, SambaNova, Tenstorrent) accelerate their own IPO plans on the back of this reception
The inference chip market just got its first public benchmark. Expect every competitor in the space to be measured against it. Full details at the original TechCrunch AI report.
