Cerebras Systems didn\u2019t just go public this week; it minted billionaires and delivered one of the biggest venture paydays in years. The A.I. chip startup<\/a> priced its IPO at $185 a share on Wednesday (May 13), above a range it had already raised twice. Shares opened at $350 on Thursday and closed at $311.07, valuing the company at roughly $95 billion. The $5.55 billion offering is the largest U.S. tech IPO since Uber in 2019 and the biggest semiconductor debut on record, serving as an early test of investor appetite for a wave of A.I. listings,<\/a> including OpenAI and Anthropic later this year.<\/p>\n

The momentum cooled slightly today, with shares falling about 5 percent intraday to around $293. Still, the IPO instantly created two billionaires and generated massive returns for a tight circle of early backers.<\/p>\n

CEO Andrew Feldman, 56, co-founded Cerebras in 2016 with four former colleagues from SeaMicro, a server company he founded and sold to AMD for $334 million. Feldman owns roughly 5.5 percent of Cerebras, a stake now worth about $3.2 billion,<\/a> according to Bloomberg. Co-founder and CTO Sean Lie holds a stake valued at approximately $1.6 billion.<\/p>\n

Feldman is a serial entrepreneur with deep roots in Silicon Valley. He grew up on Stanford\u2019s campus, where both his parents were professors, and later earned both a BA and an MBA from the university. Over the past two decades, he has helped take Riverstone Networks public and led marketing at Force10 Networks before its $800 million sale to Dell. Cerebras is his fourth company in semiconductors and data infrastructure and by far his biggest win.<\/p>\n

Earlier this year, the company\u2019s board approved what it described as a \u201cmoonshot\u201d compensation package for Feldman, awarding additional stock tied to market-cap milestones. The timing underscores Cerebras\u2019 rapid ascent: the company reported $510 million in revenue<\/a> for 2025, up 76 percent year over year, and swung to $238 million in net income after a $481 million loss in 2024.<\/p>\n

The biggest winners from the IPO also include the venture firms that backed Cerebras from the start.<\/p>\n

Benchmark, Foundation Capital, and Eclipse Ventures co-led the company\u2019s $27 million Series A in 2016. At Benchmark, Eric Vishria led the deal and remains on the board. The firm\u2019s 8.1 percent stake was worth roughly $6 billion at Thursday\u2019s close. Benchmark\u2019s conviction in the company remained strong even late in the game. In February, it raised two new funds, both called \u201cBenchmark Infrastructure,\u201d to invest another $225 million into Cerebras ahead of the IPO.<\/p>\n

Foundation Capital, where Steve Vassallo led the investment and hosted Feldman in its offices during the company\u2019s earliest days, now holds a stake valued at about $5.3 billion.<\/p>\n

Eclipse Ventures, led by founder Lior Susan, sits on roughly $5.2 billion.<\/p>\n

Later investors also saw significant gains. Fidelity, which led a $1.1 billion Series G round in September 2025 alongside Atreides Management, remains the largest shareholder at 11.3 percent. That stake is worth about $3.8 billion at the IPO price. Tiger Global followed with a $1 billion Series H in February at a $23 billion valuation.<\/p>\n

A group of high-profile angel investors also stands to benefit, including Sam Altman, Greg Brockman, Ilya Sutskever, Adam D\u2019Angelo, Andy Bechtolsheim and Intel CEO Lip-Bu Tan. Most of their stakes are too small to require full SEC disclosure, but some surfaced as part of the Musk v. Altman lawsuit.<\/p>\n

Filings in that case show Altman held roughly 89,000 shares as of December 31, now worth about $27.8 million at post-IPO prices near $311. Brockman held around 78,000 shares, valued at roughly $24.2 million.<\/p>\n

Those same filings reveal that OpenAI once explored acquiring Cerebras. In 2017, Brockman wrote that \u201cexclusive access to Cerebras hardware would give OpenAI an overwhelming hardware advantage over Google.\u201d<\/p>\n

That relationship evolved years later into a major commercial partnership. In January, OpenAI signed a multi-year compute agreement with Cerebras worth more than $20 billion for 750 megawatts of capacity through 2028. A separate $1 billion loan from OpenAI in December 2025 came with warrants for more than 33 million shares, enough for roughly a 10 percent stake. Additional warrants could be worth about $5 billion at the IPO midpoint, according to Financial Times estimates.<\/p>\n

Cerebras\u2019 blockbuster debut lands as the IPO market reawakens. U.S. IPO proceeds have more than doubled year-to-date<\/a> in 2026, with Cerebras accounting for roughly a quarter of that total. Companies like SpaceX, OpenAI, and Anthropic are expected to follow, with SpaceX and OpenAI alone projected to raise as much as $135 billion combined.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
