When Cerebras Systems debuted on the Nasdaq Thursday, the stock opened at $185 per share and quickly surged past $300, valuing the company at well over $10 billion. The meteoric rise translated into a staggering windfall for Benchmark, the venture‑capital firm that bought a majority of its shares in early rounds. At the opening price, Benchmark’s 17,602,983 shares were worth roughly $3.3 billion; at the day’s high, the same stake topped $5.3 billion. The firm cannot sell any of those shares until a six‑month lock‑up period expires.
Benchmark’s involvement began in 2016, when the firm’s general partner Eric Vishria first met the five‑founder team behind Cerebras. At the time, Vishria had been a venture capitalist for only about 18 months, having previously sold his social‑browser startup RockMelt to Yahoo for an estimated $60‑70 million in 2013. The meeting was not something he sought out. He later told TechCrunch he kept asking his assistant, "Why did you let me take this meeting?" The boardroom deck began with a title slide and a team slide, but it was the third slide that changed his mind: it argued that GPUs were fundamentally ill‑suited for deep learning and that a new class of chip could be 100 times faster than CPUs.
Even though Vishria admitted he understood little about chip design, the pitch convinced him that the team’s experience – including a previous exit when they sold SeaMicro to AMD – reduced the usual venture‑capital risk. Benchmark, known for its selective hardware bets, had not made a hardware investment in a decade. To move forward, Vishria brought the pitch to founding partner Bruce Dunlevie, who grilled co‑founder and CEO Andrew Feldman on packaging, cooling and manufacturing challenges. The meeting, Vishria recalled, felt "like a dog watching TV," but Dunlevie's endorsement helped seal the deal.
From that point, Cerebras embarked on an eight‑year engineering marathon. Feldman and CTO Sean Lie invented new cooling methods to keep a wafer‑scale chip from overheating, and they built a machine capable of drilling 40 screws into a wafer without cracking it. The company raised roughly $500 million across multiple rounds, including a half‑billion‑dollar infusion during the 2022 VC bear market. By the time the chip entered production at Taiwan Semiconductor Manufacturing Co., it proved not only capable of training large AI models but also surprisingly efficient for inference – the stage where models generate responses.
The timing proved crucial. As the AI industry’s demand for compute exploded, Cerebras secured major customers, most notably OpenAI and Amazon Web Services, alongside Abu Dhabi‑based cloud provider G42. The G42 investment later triggered U.S. national‑security scrutiny, temporarily stalling the company’s public‑market plans. The delay, however, turned out to be a blessing; it gave Cerebras time to double revenue and post a profit for the first time.
Benchmark’s financial upside is equally dramatic. The firm bought about 80 percent of its shares in the early rounds for roughly $18 million and later invested an additional $250 million at higher valuations. Those purchases now sit on a paper gain of multiple billions, rewarding Benchmark’s partners and staff with sizable bonuses. Vishria, who has been on Cerebras’s board since its inception, praised the team’s "persistence, ingenuity, and adaptiveness" in turning a risky hardware concept into a profitable, market‑leading product.
The Cerebras IPO underscores how a single, reluctant meeting can reshape a venture‑capital firm’s fortunes. It also highlights the growing importance of specialized AI hardware in a market once dominated by GPUs. For Benchmark, the bet on a wafer‑scale processor that seemed like a long shot has become one of its most lucrative hardware investments in a decade.
