Cerebras Systems has filed paperwork to go public. Again. The AI chip maker, known for its dinner-plate-sized processors, disclosed its S-1 with the SEC on April 17, 2026, targeting Nasdaq under the ticker CBRS. This comes after pulling a prior filing in 2025, just days following a $1.1 billion fundraise that pegged its value at $8 billion. Back then, regulatory snags over UAE investor G42 stalled progress. Now, with CFIUS cleared and deals like a multibillion-dollar pact with OpenAI, Cerebras eyes a mid-May debut.
Revenue hit $510 million in 2025. That’s up 76% from $290.3 million the year before. Net income swung to $87.9 million—or $237.8 million excluding one-offs—from a $484.8 million loss. But strip away a $363 million accounting gain from restructuring a G42 deal, and operating losses widened to $75.7 million non-GAAP. Boom times, yet cash burn persists. A $24.6 billion backlog looms large, fueled by that OpenAI commitment for 750 megawatts through 2028, with options to nearly 3 gigawatts by 2030. OpenAI loaned $1 billion and snagged warrants for 33 million shares.
Customers? Still UAE-heavy. Mohamed bin Zayed University of Artificial Intelligence delivered 62% of 2025 revenue; G42 chipped in 24%. Down from 87% reliance earlier. Diversity helps. Amazon Web Services integrated Cerebras inference chips into its data centers last year, per Wall Street Journal. And CEO Andrew Feldman didn’t mince words on Nvidia rivalry: “Obviously, [Nvidia] didn’t want to lose the fast inference business at OpenAI, and we took that from them,” he told Yahoo Finance.
From Wafer Dreams to Data Center Reality
Cerebras’ edge? The Wafer-Scale Engine, or WSE-3. At 58 times larger than Nvidia’s B200, it packs 4 trillion transistors, 900,000 AI cores, and memory bandwidth Nvidia clusters can’t match—2,625 times more, claims the company. No NVLink traffic jams. Just one massive die. Inference speeds? Up to 15x faster on open-source models versus GPUs. The CS-3 systems housing these beasts power sovereign AI for nations wary of Big Tech clouds. Six North American data centers hum already.
But history matters. Founded in 2015, Cerebras raised over $800 million privately, hitting $23 billion valuation in February 2026’s Series H. First S-1 in September 2024 exposed early losses: $127 million on $78.7 million revenue, per SEC filings. CFIUS scrutiny over G42—a Microsoft-backed UAE firm—derailed that. Delays piled on through 2025 amid Trump-era reviews. Then, September’s $1.1B round let them withdraw and refresh numbers, as CEO Feldman posted on LinkedIn: the prior prospectus was “stale and no longer reflected the current state of our business.”
Financials evolved. Hardware sales: $358 million in 2025, up from $212 million. Cloud services added $152 million. Gross margins? Improving, though discounts to G42 bit early. Remaining performance obligations signal confidence—15% expected in 2026-2027. Morgan Stanley leads underwriters, with Citi, Barclays, UBS in tow. A $125 million credit line expands post-IPO.
Path forward includes “disaggregated inference.” Cerebras hardware as decode engine; others handle prefill. Hybrid play. No full GPU replacement. Smart, given Nvidia’s 80% market grip.
And competition sharpens. OpenAI’s deal doubled to $20 billion over three years, per X posts from insiders like @deepakmagrawal. “The AI compute race is no longer just about Nvidia.” Cerebras chips now in AWS. Inference.cerebras.ai draws devs for speed.
Profit Mirage or Turning Point?
That 2025 profit? Paper-driven. Core ops lost money. Losses from operations: $146 million. R&D devours cash—biggest opex chunk. Scaling six data centers, more chips, sovereign deals costs plenty. UAE concentration risks persist. One client falters, trouble brews.
Yet momentum builds. CNBC notes the filing after scrapping last year’s plans. Reuters calls it a Nvidia rival tapping listings revival. WSJ highlights OpenAI, Amazon pacts post-cancellation. BusinessWire’s presser confirms S-1 details (link). PitchBook dissects the backlog’s OpenAI tilt (here).
Investors eye execution. Can Cerebras deliver $24.6 billion backlog without UAE over-reliance? Turn operating losses? Match private $23 billion valuation publicly?
Risks abound. Chip wars rage. Nvidia’s moat deepens. But Cerebras bets on inference hunger—where speed trumps all. Mid-May IPO looms. Public markets test if wafer-scale dreams scale.
