Futures markets faced significant pressure Tuesday morning as a worldwide semiconductor industry sell-off sparked renewed skepticism about artificial intelligence investment valuations.
The Nasdaq 100 futures contract declined 2.8%. The S&P 500 futures dropped 1.4%. Dow Jones Industrial Average futures decreased approximately 270 points, or 0.5%, demonstrating relative resilience thanks to lower technology sector concentration.

Memory Chip Manufacturers Lead Market Decline
South Korea’s benchmark KOSPI index crashed 10% during Tuesday’s session, driven by devastating losses among leading global memory semiconductor producers.
Both Samsung Electronics and SK Hynix experienced losses exceeding 12%. The Seoul market collapse intensified existing worries that artificial intelligence chip demand expectations have become overinflated.
Micron shares plunged 10% in pre-market activity, just one trading day after achieving an all-time closing high. The company’s Wednesday earnings announcement has become a crucial barometer for assessing memory semiconductor demand trends.
Nvidia, AMD, and Broadcom all posted pre-market losses, extending the widespread semiconductor sector downturn.
Alphabet Shares Slide Following Prominent AI Scientist’s Exit
Market confidence weakened after John Jumper, a Nobel laureate in AI research, revealed his departure from Google to join rival Anthropic.
This development triggered substantial selling pressure in Alphabet stock on Monday and intensified the technology sector selloff extending into Tuesday’s session.
SpaceX stock continued declining as well, with the company’s market capitalization at risk of falling beneath the $2 trillion threshold following three consecutive days of losses.
Cryptocurrency Markets Decline Alongside Risk Assets
Bitcoin dropped 2% to reach $62,883 during the previous 24-hour period, mirroring the broader retreat in speculative investments.
The digital currency has traded within a defined range as geopolitical tensions and Federal Reserve monetary policy uncertainty continue suppressing investor risk tolerance.
The U.S. dollar reached a 12-month peak, bolstered by safe-haven demand and market expectations for additional Fed interest rate increases.
Current market pricing suggests the Federal Reserve may implement multiple rate hikes throughout 2026, responding to persistent inflationary pressures.
Crude oil prices initially declined before stabilizing. Brent crude futures fell to approximately $76.45 per barrel while WTI dropped to $72.55, though both benchmarks later traded essentially flat following the U.S. government’s announcement of a 60-day sanctions waiver affecting Iranian oil exports.
FedEx and Cerebras Systems are scheduled to release earnings reports Tuesday. Cerebras Systems will publish its inaugural quarterly results following its May public debut, attracting significant attention within the AI chip industry.
The 10-year Treasury yield decreased 3 basis points to 4.48%, reflecting investor rotation toward defensive assets.
