Insiders React: Anthropic’s Fable, Mythos explained + SpaceX’s record-breaking IPO

The Startup Podcast is back for its 300th episode – and it’s an absolute doozy.

In today’s Reacts, hosts Chris Saad and Yaniv Bernstein break down how Anthropic became the new industry leader in AI, and why betting on coding as the 'meta domain' of AI turned out to be one of the most consequential product decisions of the decade.

They also dig into Mythos and the newly released Claude Fable: what makes Fable different, whether it has something approaching genuine intelligence, and what the Anthropic 'strategy dividend' (per Ben Thompson of Stratechery) actually means for the industry.

Then: SpaceX’s record-breaking IPO. With a reported valuation of around $1.88 trillion and a prospectus that talks more about AI than rockets, Chris and Yaniv ask the obvious question: is it worth it?

In this episode:

• How product discipline and a bet on coding put Anthropic in front

• Strategy dividends: how Anthropic's genuine commitment to safety became both a real constraint and a powerful marketing asset at the same time

• Claude’s new models, Fable and Mythos: what's actually changed?

• Why Chris thinks the SpaceX IPO at ~90x revenue is a roll-up of Elon Musk's 'dead bodies'

• Liquidity risk: with SpaceX, Google and Anthropic all raising simultaneously, is there enough liquidity in the market?
