Altimeter Capital founder and CEO Brad Gerstner stated at the All-In Podcast annual summit that the current rally in tech stocks is driven by corporate earnings rather than a valuation bubble, but the key conditions for the "AI trade" to remain valid are narrowing. He pointed out that the combined annualized revenue of three leading institutions—Anthropic, OpenAI, and SpaceX—is currently about $100 billion. For the AI trade logic to be self-consistent, this figure needs to grow to at least $180 billion by the end of this year. If the continuous capital expenditure expansion by cloud giants ultimately cannot be met by sufficient rental demand, the current aggressive investment cycle will be unsustainable. Gerstner maintains a "medium position," refusing high-leverage risks, and warned that the market in 2026 has already priced in AI expectations, so investors must follow the facts and remain flexible. He also mentioned that if frontier labs can maintain monthly revenues at a high level of $8 billion and oil prices fall, suppressing long-term interest rates, he would consider further increasing positions; otherwise, he reserves the right to reduce positions. He simultaneously warned that if the 10-year U.S. Treasury yield rises to 5.5%, stock valuations will face significant pressure.
