E133: Market melt-up, IPO update, AI startups overheat, Reddit revolts & more with Brad Gerstner

AI is threatening the web’s “10 blue links” model, shifting the valuable top-of-funnel toward conversational agents and knowledge extraction. After discussions with DeepMind co-founder Mustafa Suleyman and Expedia/Zillow founder Rich Barton, Brad Gerstner said Google is well positioned technically but must reinvent AI search without destroying the economics of its core business.

Reddit’s API revolt exposed how much of its enterprise value depends on moderators and users it does not employ. With roughly 95% of Reddit reportedly going dark and Apollo facing about $20 million annually in API fees, Chamath argued Reddit should have established meaningful revenue-sharing with moderators before aggressively monetizing their ecosystem.

The panel’s sharpest AI-investment warning was that venture firms may be using expensive equity to finance rapidly depreciating computing hardware. Mistral reportedly raised $105 million before building a product, while Friedberg argued that model-training costs could collapse so quickly that today’s $100 million compute expenditure may soon buy little durable advantage.

Gerstner said his firm had already rejected more than 60 AI companies because being right about the platform shift does not mean early investments will win. He compared the frenzy with 1990s search, when most contenders disappeared, and favored pacing capital toward applications, specialized models and tools that can build customers and defensible advantages now.

CalPERS is reversing years of minimal venture exposure, with plans discussed to expand from roughly $800 million to $5 billion. Chamath attacked the pension fund’s previous allocation process, while Gerstner—after interacting with its new team—said it is now pursuing concentrated strategic partnerships and thematic bets around major technology cycles such as AI.

Public-market investing materially changed how Gerstner evaluates venture risk. He said his firm stopped making venture investments in October 2021 because public markets looked unhealthy, and described another major VC firm finding public-market experience useful for pricing private investments and deciding when to distribute public shares to limited partners.

Gerstner remained bullish on Nvidia’s business while treating its extraordinary stock move as a reason to hedge rather than abandon the position. He cited Nvidia raising its quarterly revenue guide from $7 billion to $11 billion as shares climbed from about $125 to above $400, and said selling six-month calls could lock in roughly 20% yield.

The proposed Arm IPO was framed primarily as a liquidity event for SoftBank, not an obvious bargain for new investors. SoftBank had paid $32 billion in 2016, while Chamath valued Arm around the mid-$20 billions despite reports of a possible $70 billion valuation; Gerstner said post-2021 IPO buyers would demand substantially larger discounts.
