Trending on Reddit: Cerebras IPO Pops 68%, Mints Two Billionaires
What Happened
Cerebras became 2026's largest IPO, with shares surging 68% from the offer price. Co-founders Andrew Feldman and Sean Lie are now worth roughly $3.2 billion and $1.7 billion respectively on paper. The wafer-scale chip maker positioned itself as the credible non-Nvidia inference play, and public-market investors clearly bought the thesis.
My Take
The market is now openly betting that the inference layer gets disaggregated from Nvidia, and Cerebras was the cleanest public proxy available. But a $100B valuation on a company that still does a tiny fraction of Nvidia's revenue is also the clearest sign yet that we're in the speculative phase of this cycle. If you're an exec running procurement, don't get romantic — keep buying the chips that actually ship in volume. The IPO pop is a story about capital flows, not silicon.
