- John Jumper, a Nobel laureate in AI research, departed Alphabet’s Google to join rival startup Anthropic
- South Korean KOSPI index crashed 10%, pulling Samsung Electronics and SK Hynix down more than 10%
- Bitcoin declined 2% to approximately $62,883, mirroring widespread market risk aversion

Technology equities are poised for another turbulent trading day Tuesday following a Nobel laureate’s career move and mounting anxieties surrounding artificial intelligence chip demand that unsettled investors worldwide.
Nasdaq 100 futures tumbled by as much as 2.6% during premarket hours. S&P 500 futures declined 1.5%, while Dow Jones Industrial Average futures retreated approximately 350 points, representing a 0.7% drop.
The market downturn comes on the heels of a challenging Monday for mega-cap technology companies. The primary catalyst: John Jumper, a Nobel Prize-winning artificial intelligence researcher at Alphabet’s Google, revealed his decision to depart for AI startup Anthropic. The announcement pressured Alphabet stock lower.
Jumper gained recognition for his groundbreaking contributions to protein structure prediction. His transition to a competing AI laboratory unnerved investors who monitor top-tier talent movements as barometers for artificial intelligence industry momentum.
South Korean Semiconductor Stocks Deepen Market Woes
The technology sector challenges extended beyond American borders. South Korea’s KOSPI Composite index plummeted 10% Tuesday, marking one of its most dramatic single-day declines in recent history.
Memory chip manufacturers Samsung Electronics and SK Hynix both tumbled over 10%. These corporations serve as critical benchmarks for AI hardware demand trends, given their role as primary suppliers of memory chips deployed in AI server infrastructure.
Their precipitous decline intensified questions about whether artificial intelligence infrastructure investment will maintain the trajectory markets had anticipated. These concerns subsequently rippled through to US technology futures, dampening investor sentiment ahead of the American trading session.
SpaceX, which trades on secondary markets through a special purpose vehicle, declined for the third consecutive day.
Focus Shifts to Corporate Reports and Inflation Metrics
Tuesday features two significant earnings announcements. FedEx is scheduled to report results alongside Cerebras Systems, the artificial intelligence chip manufacturer that completed its initial public offering in May. This marks Cerebras’ debut earnings report as a publicly traded entity.
Market participants are also anticipating Micron’s earnings release Wednesday. As a major memory chip producer, Micron’s financial results will serve as a crucial indicator of whether AI-driven chip demand remains resilient following the Korean market selloff.
The Federal Reserve’s preferred inflation measure, the PCE index for May, arrives Thursday. Markets remain on edge regarding the potential for multiple rate increases during 2026.
US-Iran negotiations proceeded quietly in the background. Crude oil prices retreated on optimism that diplomatic progress could restore supply flows through the Strait of Hormuz. Brent crude fell 1.9% to $76.45 per barrel.
Bitcoin dropped 2% to roughly $62,883, tracking the broader risk-averse market sentiment. The 10-year Treasury yield declined 3 basis points to 4.48%, while the dollar climbed to a one-year peak against a basket of currencies, propelled by safe-haven flows and expectations of elevated US interest rates.
With Cerebras and Micron both scheduled to report within the coming 48 hours, these releases could fundamentally alter market sentiment toward the AI investment thesis as summer approaches.
