AI chipmaker Cerebras revives IPO plans after $1.1B raise and CFIUS clearance

AI chipmaker Cerebras Systems is moving back toward the public markets.

The Sunnyvale-based startup is preparing to file for a U.S. initial public offering as early as next week, with a listing targeted for the second quarter of 2026, according to an exclusive Reuters report, citing people familiar with the matter. The plan marks a reversal after months of delays tied to national security scrutiny and a record-setting private funding round.

“AI chip maker Cerebras Systems is preparing to file for a U.S. initial public offering as soon as next week, targeting a second-quarter 2026 listing,” Reuters reported.

The renewed IPO push comes roughly two months after Cerebras raised $1.1 billion at an $8.1 billion valuation, a deal that placed its public debut on pause. The company had already filed confidentially with the U.S. Securities and Exchange Commission in June 2024, followed by a public filing in September. That effort stalled after the Committee on Foreign Investment in the United States reviewed ties between Cerebras and the Abu Dhabi-based tech group G42.

Cerebras Resumes IPO Push as CFIUS Review Ends and G42 Exits

Cerebras withdrew its IPO paperwork in October, days after announcing the funding round. Reuters later reported that concerns tied to G42’s minority stake played a central role in the review process. U.S. officials had raised concerns about whether Middle Eastern firms could create indirect pathways for advanced American AI technology to reach China.

Founded in 2016 by CEO Andrew Feldman, Cerebras has built its reputation on a single, audacious idea: wafer-scale computing. Its flagship Wafer-Scale Engine 3 spans an entire silicon wafer and packs 900,000 AI cores and four trillion transistors. The company says the approach eliminates the need for complex chip-to-chip connections in GPU clusters, enabling inference speeds more than 20 times faster than competing systems.

Earlier this year, Cerebras said it had received clearance from CFIUS. In the new filing, G42 no longer appears on the company’s investor list, according to a source. The reason for the change remains unclear. G42 previously served as both a minority investor and one of Cerebras’ largest customers. The firm did not respond to requests for comment.

Cerebras now returns to the IPO path with a cleaner ownership structure and fresh capital in the bank. The company continues to position its wafer-scale engines as an alternative to Nvidia’s GPUs for training and running large AI models, setting the stage for one of the most closely watched hardware listings of 2026.
