Inside OpenAI’s $500B Valuation | Altimeter’s Largest Bet

With $10B+ in AUM, Altimeter has made their largest bet in its history on OpenAI. Known for disciplined bets in generational companies like Snowflake, SpaceX, Anduril — and now OpenAI, the firm is now fully committed to the AI supercycle.

In this episode, Apoorv Agrawal, Partner at Altimeter focused on AI and software, joins Molly O’Shea to break down how the firm evaluates opportunities in the AI supercycle. Apoorv explains why power laws govern venture returns, how Altimeter evaluated the $500B+ OpenAI opportunity, and why speed is the only defensible moat in AI.

We also explore the AI talent wars reshaping Silicon Valley, the rise of XBOW (where AI agents are already outperforming humans), and lessons from Apoorv’s formative years as a forward deployed engineer at Palantir — a culture that has produced billions in founder-led value creation.

For institutional investors, allocators, and operators, this conversation offers a rare inside look at how one of the sharpest minds in venture is positioning around AI — from infrastructure and chips to applications and talent.
