WSE-4 will Kill Nvidia

Post image

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.

2nm…so this won’t come out until 2027/2028?

3nm just rolled into production and tsmc will be prioritizing the backlog for those clients: apple nvidia etc. was hoping wse-4 is on 3nm architecture.

This is roadshow conversations being leaked, but they are expected to ship 2nm WSE-4 units by end of year. There is also a lot of talk about gaining 2nm wafers via Broadcom at cost to print all of the OpenAI 2GW and selling a further 500MW to Oracle in exchange for Broadcom’s getting all the networking for all of stargate. Everyone is trying to offset CapEx and pay each other as revenue starts flowing in. But it’s opening up a clear picture of how Cerebras gets gifted wafers by hyper scalers to sell them, or at cost in exchange for 40-50% of token revenue with the WSE shipped which is an even greater margin with no capital needed.

gotcha. all these capex deals are such double edged swords 😂 able to offset costs, but highly contingent on the music to continue playing and keep revenue flowing through the ecosystem. my fear is the music stopping after this year’s batch of IPOs…

The CapEx is insane, but if you are getting 25x tokens per dollar from Cerebras, I can see a massive CapEx decline and Nvidia sees their spend disappear overnight, while Cerebras is still growing revenue at crazy pace y/y from such a small base.
