Shares shifted dramatically as Cerebras Systems stormed onto the Nasdaq Thursday, closing up 68% at $311.07 on its first day and climbing another 6.9% to $332.52 in Friday pre-market trading. Demand exceeded available shares by more than 20 times , making this the year's most overhyped — and most revealing — litmus test for how far investors will stretch to own a piece of the AI chip race.
A Blockbuster Offering That Kept Getting Bigger
Cerebras priced at $185 — far above the original $115–$125 range, which was later hiked to $150–$160 — while increasing the offering size to 30 million shares.
The IPO raised $5.55 billion and valued the company above $66 billion on day one. In plain terms, the market valued Cerebras at roughly 130 times its annual sales — a price that demands near-flawless execution for years.
Two Clients Account for Nearly All the Revenue
G42 contributed 24% of 2025 revenue (down from 85% in 2024), but a UAE-based AI university picked up the slack at 62%. That means roughly 86% of the company's $510 million in revenue depends on just two buyers. If either relationship cools, the growth story collapses. A deal with OpenAI worth over $20 billion for computing capacity helps diversify, but that contract runs only through 2028 and hasn't yet materially reshuffled the revenue mix.
The Profit Picture Is Murkier Than Headlines Suggest
Cerebras reported $237.8 million in net income in 2025 after losing nearly half a billion the year before. But that swing was driven largely by a one-time accounting gain — a "change in fair value" of a financial contract — not core operations.
The company still posted a $145.9 million operating loss, with R&D spending eating 48% of sales.
A Looming Sell-Off Date Investors Shouldn't Ignore
The 180-day insider lockup expires around mid-November 2026.
CEO Andrew Feldman's stake was worth nearly $1.9 billion at the IPO price , and co-founders plus early backers hold billions more. When that lockup lifts, a wave of insider selling could hit a stock already priced for perfection. For now, the AI frenzy carries the day — but gravity has a habit of showing up eventually.
