Ark Invest bought 93,290 Cerebras Systems shares (~$17.2M) and sold 7,600 AMD shares (~$3.5M), signaling a tilt toward Cerebras’ AI-inference chips as the company unveils its CS-4 system with high-throughput claims and potential Meta as a customer, while Cerebras remains IPO-era risky but with a bullish price target around $296.
Cerebras Systems (CBRS) posted Q2 revenue of $180.1M, up 74% year over year, but hardware sales slipped to $54.1M amid lumpy demand and data-center space constraints while its cloud-services revenue jumped to $126M. The company swung to a net loss of $450.5M largely due to $386.6M in stock-based compensation. Cerebras raised its 2026 core revenue guidance to $214–216M and now sees full-year revenue of $880–890M, with a plan to more than triple revenue in 2027 as production scales; the market reacted with about a 15% after-hours drop as investors weigh the mix of cloud momentum against hardware headwinds, and the company continues to push against Nvidia with partnerships and OpenAI integration for its Wafer-Scale Engine.
Cerebras Systems’ stock fell about 16% after-hours after a Q2 revenue miss, with revenue of $180.11 million vs $194.23 million expected and an adjusted loss of $6.91 million, though the cloud business grew to $126 million and total sales rose 74.3% to $180.11 million. The company raised 2026 revenue guidance to $880–$890 million and expects 41–43% gross margin as it scales its wafer-scale engine amid intense competition from Nvidia; a multiyear OpenAI compute deal remains a key growth driver.
Cerebras Systems CEO Andrew Feldman said investors misunderstood the company’s 2026 adjusted gross margin guidance of 38-41% (versus 47% in Q1), arguing the plan laid out at the IPO is being beat and that margins won’t be a straight line as the company scales. The upbeat framing comes after the stock fell more than 17% following the earnings report. Feldman pointed to positives like OpenAI’s GPT-5.4 running on Cerebras chips and AWS data-center deployments, while noting logistics such as renting back equipment from a major client will influence near-term margins and growth.
Cerebras stock has slid about 22% since its May IPO pop, despite touting wafer-scale AI chip technology meant to speed inference. Backed by large OpenAI and AWS deals that create a substantial revenue backlog (roughly $24.6 billion in remaining obligations), the upside is tied to the company’s ability to scale production and operations with limited supplier capacity. Risks include execution challenges, dependence on Taiwan-based TSMC, and customer concentration, all set against a lofty valuation (~$55 billion market cap and ~108x 2025 sales). The Motley Fool notes this doesn’t look like a compelling buy at current prices and isn’t among their top stock picks.
Cerebras Systems (CBRS) stock fell more than 5% in premarket trading on its second day of trading after an IPO that priced at $185 and opened at $350, an 89% jump from the offering price, as investors weigh demand for AI hardware.
Cerebras Systems began trading on Nasdaq with an IPO priced at $185 and closed its first session around $311.07, up about 68%, in what was the largest IPO of 2026 so far. The company raised roughly $5.55 billion by selling 30 million shares, valuing it near a $67 billion market cap. Cerebras, whose wafer-scale AI chips power systems like CS-2 and CS-3, counts OpenAI, Amazon and Meta among its customers and is pitched as a rival to Nvidia, albeit far smaller. Revenue has grown rapidly (2022–2025: from $24.6M to $510M in 2025), but the company remains unprofitable on an operating basis, with 2025 R&D at about 48% of sales and negative operating cash flow (~$10.1M). Analysts note potential index inclusions (S&P 500, Nasdaq-100) could provide tailwinds, but Fool’s Stock Advisor does not list Cerebras among its current top picks, underscoring the stock’s growth-story risk and the need to watch profitability as it scales.
Cerebras Systems is planning to raise the size and price of its IPO, considering a new price range of $150-$160 per share and up to 30 million shares, potentially pulling in about $4.8 billion, as demand for AI chips remains strong; the offering is set for Nasdaq under the symbol CBRS with pricing expected May 13, and orders have run more than 20x the available shares. The company counts Amazon and OpenAI among customers and previously paused its 2024 IPO after a CFIUS review of its G42 partnership, which has since been cleared.
