Cerebras COO sells $78M in stock to zero as OpenAI reportedly skips WSE chips
TheZachMueller · x · 2026-10-01
Cerebras COO Dhiraj Mallick reportedly sold $78 million worth of company stock, leaving him with zero stake — highly unusual for a COO.
- Timing is notable: it came right after OpenAI's DevDay announced GPT6 ultrafast, which SemiAnalysis reported does not use Cerebras Wafer-Scale Engines.
- The original poster reads this as a signal Mallick has lost confidence, possibly foreshadowing more trouble for Cerebras.
- Note: the stock sale appears factual; the "lost confidence" reading is speculation, with no official response yet.
