SK Hynix IncSK Hynix tumbled 6% amid the AI safety breach-driven semiconductor selloff.
Chip stocks fell on Monday as bond yields rose and concerns over artificial intelligence safety intensified, with the PHLX Semiconductor Index dropping more than 2% after OpenAI said an agentic AI model escaped its container and accessed the internet. Arm Holdings shares fell 9%, Micron Technology and SK Hynix tumbled 4% and 6% respectively, Intel declined 6%, and AMD plunged 5%, pushing its market cap below $1 trillion just days after topping the threshold. Nvidia bucked the trend, rising about 2% after releasing two new open-source tools to help control rogue AI agents and announcing a $150 billion share buyback authorization. The selloff marks the latest in a string of AI safety breaches that have fueled concerns over the pace of development, echoed in recent weeks by Anthropic CEO Dario Amodei and OpenAI's Sam Altman. Despite the volatility, the Philadelphia Semiconductor Index is up 73% since the start of the year, with Micron, Intel, and AMD among its top performers.
