AI Executives Call to Slow Development, AI Stocks Plunge Worldwide
Multiple leading AI executives publicly warned about risks of overly fast AI development and called for slowing down, after which AI-related stocks worldwide fell sharply — the most direct threat yet to tens of billions of dollars in AI investment.
Confirmed
- Anthropic CEO Dario Amodei published "We Must Pace the Frontier," urging the industry to slow "reckless" AI development
- According to Reuters, Altman publicly backed Amodei's call; Google DeepMind's Demis Hassabis and Elon Musk also endorsed it, citing safety concerns
- Per Reuters, Asian AI stocks plunged Monday: SoftBank fell as much as 13.2% intraday, Kioxia dropped 9.8%, SK Hynix fell 5.3%; per the Financial Times, AI stocks fell as much as 13% in a single day
- Per market data cited by economist Alex Tabarrok: SoftBank closed down nearly 11% — it holds about 13% of OpenAI, seen as the first real market pricing vote on OpenAI equity; ASML fell 6%, SK Hynix closed down 6.4%
- Per The Guardian, investors began reassessing AI companies' value; the AI sector had previously driven global stock markets to record highs
- Per The Guardian, Altman said OpenAI will not go public this year
- AI critic Gary Marcus asked whether recent market volatility stems from investor anxiety about AI, suggesting markets may be repricing AI stocks
Why it matters
- This is the first time top lab executives have so collectively and publicly called for braking their own industry, a sharp reversal of the prior acceleration narrative
- The selloff suggests investor confidence in AI valuations may be wavering; SoftBank's plunge is seen as a direct market pricing of OpenAI's value
- Poster koltregaskes observed that consecutive statements from frontier labs over recent days directly catalyzed this shift in market sentiment
