The reporters assess Brin’s likely victory over Prop 40 and what that result would say about his new political strategy.
The brief
Sergey Brin has moved from relatively limited political giving to roughly $100 million against California’s proposed billionaire tax, Prop 40.
Jeremy White and Will McCarthy frame Brin’s campaign as a national test of Silicon Valley’s growing political influence and billionaire donors’ electoral reach.
Building a Better California combined advertising with support for other ballot measures, turning the tax fight into a broader contest over California policy.
The episode then shifts to a CFTC request for input on futures markets for AI compute, which could help companies hedge volatile infrastructure costs.
Compute futures face basic market-design problems: limited public pricing data, opaque bilateral deals, and uncertainty over how different forms of compute should be valued.
