Cerebras Systems Inc A (CBRS) surged 14.85% to $251.49 in morning trading on August 17 driven by a combination of upbeat earnings guidance and a Wedbush analyst report highlighting progress in a potential $20 billion OpenAI partnership. The stock opened with a 3.0% gap up and reached an intraday high of $261.08 before settling near $251.31. The move follows a recent downward revision to its price target by Citi and a broader context of investor interest in high-growth tech plays.
What Happened
Cerebras Systems raised its full-year 2026 revenue guidance to $880 million to $890 million, exceeding the consensus of $864.4 million. It also projected Q3 revenue of $214 million to $216 million, slightly above the $212.0 million consensus. Wedbush cited signs of progression in Cerebras' collaboration with OpenAI, particularly in the development of GPT-5.6 Sol Ultrafast mode, as a catalyst for investor optimism. The stock also saw a recent price target cut from $340 to $320 at Citi, but this was overshadowed by the positive guidance and partnership speculation. Meanwhile, Tiger Global Management disclosed a new stake in Cerebras with 2,999,000 shares.
What The Data Shows
The stock opened at $225.64, up 3.0% from the prior close, and traded as high as $261.08 before settling at $251.31. Volume reached 5.8 million shares, significantly above its average. Over the last 8 sessions, the stock rose 3.7% from $214.30 to $222.22. Insiders, including CEO Andrew Feldman and COO Dhiraj Mallick, have sold shares totaling $20.7 million in the past 90 days. The stock is currently trading within its 52-week range of $160.81 to $386.34 and has printed 15 fresh 52-week highs on August 17.
What To Watch
Cerebras Systems is not scheduled to report earnings in the near term. Investors should monitor the breadth of coverage and any further developments in the OpenAI partnership, as well as unusual options activity, which has shown balanced call and put premiums of $1.1 million each in the last 36 hours.
