Cerebras' IPO delivered a massive valuation jump amid strong AI chip demand, while Kevin Warsh's Senate confirmation as Fed chair highlighted political tensions. The episode also covered closing arguments in the Musk-OpenAI trial, Jensen Huang's China trip, and a humanoid robot demo raising autonomy questions, blending AI hardware advances with economic and legal updates.

Cerebras IPO Surges on Proven Speed Demand

Cerebras, a wafer-scale chip designer, saw its shares rise to $300-$350 on debut, pushing market cap to $64 billion—far exceeding pre-IPO predictions capped at $50 billion. The company etches entire wafers into giant chips rather than dicing them into smaller units, addressing yield issues via redundant cores that activate only defect-free sections. This approach works in practice: OpenAI uses Cerebras chips for Codex 5.3 under the name Spark, delivering instant full responses instead of streaming tokens, which improves usability for coding and queries.
