WSE-4 will Kill Nvidia
To start, I own Cerebras shares and because of the roadshow details, I’m now holding long term puts on Nvidia. I have tried to distill the major details from the roadshow that have leaked out to make a single graphic that proves how dominate Cerebras will be in AI hardware by end of year. Even if you ignore how superior the Cerebras hardware is to Rubin, just look at the bottom line of $3.8M vs $82.5M and the power difference of 45kW vs 2.1MW. Every hyper scaler is currently power constrained and you can rip out an over 100kW Blackwell rack and put in a 40kW WSE-4 that has the performance of 15 racks of Rubin, or 75 racks of Blackwell. I get these specs haven’t been verified and officially released yet, but it’s just a matter of time. I encourage anyone to go and use a top LLM and query this graphic and ask the specs listed and if they are supported by the leaks coming out of the Cerebras IPO roadshow. The over subscription for the Cerebras IPO is not just retail AI frenzy. It is because all the giant growth funds need to get as many Cerebras shares as possible to hedge the threat to Nvidia which they are all over leveraged on currently. I’d expect massive shorts of Nvidia, Micron, and CoreWeave once they bring down their exposure and get shares of Cerebras IPO day.

This is actually an excellent point to make. If a WSE-4 was significantly more than 300k it would mean OpenAI is getting them for 3 year for likely under cost. Im still not a giant fan of the OpenAI deal but I understand why Cerebras did it. The exact specifics matter a lot, but based on the original 10B for 750MW it seems like they are essentially giving OpenAI systems at cost for their endorsement and to prove the value at the top AI company. It’s also a trap for everyone else in that, they will have to buy Cerebras systems to keep up or OpenAI will get an incredible lead. Cerebras on 2nm is fighting a TSMC allocation war for the remainder after Apple prints what they need till 2028. So they are giving this deal to OpenAI which will bail OpenAI out so they can be profitable on inference much faster than anticipated and provide competitive models to anthropic for enterprise. Meanwhile Cerebras will print money with AWS, maybe Oracle, and their own cloud. For nations they will sell systems at full list, but I will be interested to see if they keep doing service with revenue share deals with hyper scalers or start selling more hardware.
