Cerebras Systems (CBRS)

Cerebras Systems (CBRS) builds wafer-scale AI processors 58 times larger than NVIDIA’s B200 and sells them as fast-inference systems and cloud services. Revenue grew 76% to $510 million in 2025, OpenAI signed a deal worth more than $20 billion, and its May 2026 Nasdaq IPO raised $5.55 billion. It reports first results on June 23, 2026.

What does Cerebras do?

Cerebras makes the Wafer-Scale Engine (WSE), the world’s only commercialized wafer-scale processor: a single piece of silicon carrying 900,000 compute cores, 44 gigabytes of on-chip memory, and 21 petabytes per second of memory bandwidth. The WSE-3 is 58 times larger than NVIDIA’s B200 chip and has 2,625 times more memory bandwidth than the B200 package (Cerebras S-1, Apr 17, 2026). The company sells that chip two ways: inside CS systems deployed on premises, and through a cloud service that rents out what it markets as the fastest AI inference available. The ramp behind the IPO was steep: revenue grew from $24.6 million in 2022 to $78.7 million in 2023, $290.3 million in 2024, and $510.0 million in 2025, a 76% jump in the final year (Cerebras S-1). Its disclosed significant customers are OpenAI, G42, MBZUAI, and AWS.

How is AI driving Cerebras’s business?

Through the market’s turn toward fast inference. As AI usage shifts from human chat queries to continuous agent workloads, token consumption compounds, and Cerebras claims its architecture serves inference up to 15 times faster than leading GPU-based solutions (Cerebras, Jun 9, 2026). The thesis converted into contracts in 2026. In January, OpenAI agreed to deploy 750 megawatts of Cerebras compute under a multi-year master agreement the S-1 values at more than $20 billion through 2028, with the two companies co-designing future models for future hardware (CNBC, Jan 14, 2026; Cerebras S-1). In March 2026, AWS began distributing Cerebras inference through its cloud, opening a second channel to enterprises and startups (Cerebras S-1). Co-founder and CEO Andrew Feldman described the demand pattern on listing day:

“There’s some whales out there, there’s some really big customers. That is one of the characteristics of this market.”

— Andrew Feldman, co-founder and CEO, Cerebras (CNBC, May 14, 2026)

What did Cerebras report most recently?

The latest audited numbers are the full-year 2025 results in the S-1: revenue of $510.0 million, up 76%, a 39.0% gross margin (down from 42.3% as inference-cloud capacity costs ramped), GAAP net income of $237.8 million against a $481.6 million net loss in 2024, and a non-GAAP net loss of $75.7 million once stock-based compensation and forward-contract fair-value items are excluded (Cerebras S-1, Apr 17, 2026). The IPO itself was the other headline event: 30 million Class A shares priced at $185 on May 13, 2026 for gross proceeds of about $5.55 billion (Cerebras, May 13, 2026), and the stock closed its first Nasdaq session at $311.07, up 68%, valuing the company at roughly $95 billion in the largest US tech IPO since Uber’s 2019 debut (CNBC, May 14, 2026).

What is Cerebras’s guidance?

None yet, by design: Cerebras has not issued public financial guidance as a newly listed company. Its first earnings report, for Q1 2026, arrives after market close on June 23, 2026, a date confirmed on June 9 (Cerebras, Jun 9, 2026). Until then, the forward anchor is contractual rather than guided: the OpenAI master agreement worth more than $20 billion deploys 750 megawatts in stages starting in 2026, so the first prints will show how quickly that ramp converts into recognized revenue (Cerebras S-1).

What are the risks for Cerebras?

• Customer concentration. Two UAE-linked customers were 86% of 2025 revenue: MBZUAI at 62% and G42 at 24%, after G42 alone was 85% in 2024. The first IPO attempt in September 2024 was withdrawn largely over scrutiny of that reliance (Cerebras S-1; CNBC, May 14, 2026).
• NVIDIA and the GPU ecosystem. Cerebras competes against the industry-standard CUDA stack, and NVIDIA bought assets from inference-chip startup Groq for $20 billion in December 2025, a direct move into Cerebras-style fast inference (CNBC, May 14, 2026).
• Capital intensity of the cloud pivot. Serving inference requires data-center capacity ahead of revenue; gross margin already slipped from 42.3% to 39.0% in 2025, and the company expects to need significant additional capital (Cerebras S-1).
• New-issue volatility. The stock closed its first day up 68% at a ~$95 billion value against $510 million of trailing revenue and a non-GAAP loss, so the valuation embeds the OpenAI ramp executing on schedule (CNBC, May 14, 2026).
