Home/News Feed/Cerebras shares drop 50% after losing key OpenAI contract to Nvidia and insider selling pressures stock. Cerebras Systems' stock has fallen about 50% since its May IPO, hitting its lowest price as it lost a major inference workload contract for OpenAI's GPT-6.1 Sol AI model to Nvidia. This setback, combined with insider selling following the expiration of lockup periods, has put significant downward pressure on the stock. Cerebras had initially excited investors as a potential alternative to Nvidia with its custom AI chips, but losing OpenAI's contract challenges its growth prospects. The company's market cap has dropped from $95 billion at IPO to just over $39 billion, and more insider shares are expected to enter the market, potentially adding further pressure.
Cerebras Systems currently holds a market cap of $40.27 billion on Pluang as of Oct 03, 2026 05:02 WIB, with a 1-day price change of -1.54%. Despite the recent stock struggles mentioned, Pluang data shows a strong buy interest with 92% of order activity favoring purchases and a typical hold time of just 3 days. Meanwhile, Nvidia trades at $233.91 with a market cap of $5.57 trillion and a dividend yield of 0.44%, showing more stable investor behavior with a longer typical hold time of 115 days and predominantly sell orders at 79%.
