Bottom line: Cerebras went public at a $60 billion valuation, but TSMC wafer production bottlenecks are expected to constrain capacity through 2028.
Cerebras has gone public and is valued at $60 billion. The stock closed on its first trading day at $280, based on a 750-MW partnership and an investment/business agreement worth $13 to $20 billion with OpenAI.
Cerebras has successfully completed its IPO following an originally filed and subsequently withdrawn S-1 registration. The $60 billion valuation positions the company as a significant player in specialized AI infrastructure and inference hardware. The stock opened at $280 without major price movements at the start of trading.
The timing of the IPO follows significant financing events: a 750-MW partnership agreement and the aforementioned investment agreement with OpenAI valued at $13 to $20 billion. Cerebras is already in productive use at OpenAI, which demonstrates an established customer relationship in contrast to competitors such as Groq. For practitioners, this means Cerebras hardware is being deployed in productive AI workloads.
Industry analysts, however, point to significant capacity constraints: wafer availability and TSMC capacity are expected to remain tight through at least 2028. This limits production volumes and thus growth potential despite the high valuation. Practitioners should therefore factor in longer lead times when planning hardware procurement.
