Market Reaction on September 14
On September 14 AI-linked equities tumbled worldwide after top AI executives warned of existential risks. The Nasdaq 100 opened 1.2 % lower, reaching a six-week trough, while the Philadelphia chip index slid 5.2 %. Leading chip makers fell sharply: Nvidia down 3 %, Advanced Micro Devices off 4.5 % and Micron down 5.4 %. Equipment makers Lam Research, Applied Materials and utility Bloom Energy each lost more than 6 %. In Europe, the tech sector dropped 2.2 % as ASML fell 6 % and Infineon and Siemens Energy slipped. Asian markets mirrored the trend, with SoftBank plunging over 10 % and chipmakers TSMC and SK Hynix retreating.
Key Voices Behind the Warning
Anthropic CEO Dario Amodei published an essay urging AI firms to slow model-capability advances, warning that agents could “take over the entire internet” within six to twelve months. Elon Musk, head of xAI, and Sam Altman, CEO of OpenAI, publicly agreed with Amodei’s call. Altman also said OpenAI would not pursue an IPO this year, citing safety concerns.
Policy and Regulatory Response
U.S. Senate negotiators are debating legislation that would require AI companies to demonstrate reasonable precautions. President Donald Trump dismissed the concerns as a “sick conspiracy” targeting AI and data-center projects. The United States and China are slated to discuss AI safety in bilateral talks this month. China’s state-backed Global Times labeled the Anthropic essay a “Cold War playbook” aimed at curbing Chinese technological progress.
Data and Market Impact
The selloff underscored the sector’s reliance on debt-financed spending amid rising bond yields. Analysts note that record capital commitments suggest AI development may remain robust despite the warnings. Deutsche Bank warned that “the competitive race between companies and countries remains intense, and it’s difficult to imagine firms voluntarily stepping back while rivals continue to push ahead.” Morgan Stanley projects AI-related spending to exceed $1.3 trillion by 2027.
