   Aswath Damodaran on whether US stocks are in a bubble and the AI market delusion

   • Damodaran argues the S&P 500 is richly priced but not bubble-priced, since the market's benign expectations have so far been validated by delivered earnings and a resilient economy.
   • He describes the 'big market delusion' as a recurring feature of major disruptions like PCs, the internet, and social media, driven by overconfident entrepreneurs and VCs who collectively overprice companies chasing a big market.
   • He insists bubbles and corrections are a feature, not a bug, of market economies, because innovation requires overreach — a world run by actuaries would never leave the cave.

   Where the AI delusion actually sits: architecture versus products

   • Damodaran splits AI into the architecture side (Nvidia, data centers, power companies) and the product/service side (LLMs), arguing the architecture is the 'easy half' because spending there is certain to show up.
   • The uncertainty and delusion lie in LLM companies like OpenAI, Anthropic, and xAI, which are collectively overvalued because there isn't enough endgame revenue to justify current pricing.
   • He compares LLMs to the smartphone: just as DoorDash and Airbnb capture the value built on the iPhone, LLM value will accrue to companies that build products and services on top of the models, not the models themselves.

   Advice on private AI companies and the coming cleanup

   • Since OpenAI, Anthropic, and xAI are private, VCs can only be long and cannot short, so Damodaran advises staying away unless you have technological expertise to pre-identify the winner.
   • Once these companies go public, early trading will be a 'trader's paradise' driven by mood and momentum, and investors bringing valuation discipline will get 'eaten alive'.
   • He predicts a cleanup phase with massive impairments of AI investments, but notes Nvidia won't have to return cash for chips already sold — the mistakes become sunk costs.

Konsep utama

• big market delusion— Damodaran's core concept that collective over-optimism in a disruptive market leads to systematic overvaluation even when individual companies may succeed.
• AI bubble— The central debate of the episode: whether the massive AI investment cycle constitutes a bubble, and where the real risk lies.
• LLM overvaluation— Damodaran argues the real delusion is in private LLM companies like OpenAI and Anthropic, not in the public infrastructure players.

Kutipan penting

• For change to happen in economies, you need people to overreach. The consequence of that is you're going to have market bubbles and market corrections. They're a feature, not a bug.

  💡

  — It reframes bubbles from a market failure to a necessary engine of innovation, overturning the common assumption that bubbles are purely destructive.
