The AI chipmaker told the SEC its year-old prospectus had gone stale, days after a Fidelity-led $1.1 billion round valued it at $8.1 billion; it listed on Nasdaq the following May.

Cerebras Systems withdrew its US IPO registration, telling the Securities and Exchange Commission it did not intend to proceed with the offering “at this time.” The withdrawal came three days after the wafer-scale AI chipmaker closed a $1.1 billion Series G funding round, led by Fidelity and Atreides Management, that valued the company at $8.1 billion.
Cerebras had first filed confidentially for an IPO in September 2024, more than a year earlier, and chief executive Andrew Feldman said the original prospectus had become “stale” and no longer reflected the state of the business. The original S-1 had also disclosed that a single customer, the UAE-based Group 42, accounted for more than 80% of Cerebras’s revenue in 2023 and early 2024 — a concentration risk that had drawn scrutiny during the long review process and that the fresh private round, at a materially higher valuation than the company’s prior public filings implied, may have made easier to address privately rather than under public-market disclosure requirements.
A company spokesperson said Cerebras still hoped to go public “as soon as possible.” It refiled and completed its IPO on Nasdaq under the ticker CBRS the following May, at a valuation well above the $8.1 billion set by the October 2025 private round — underscoring how quickly private AI-infrastructure valuations were moving relative to the pace of public-market listings.
