US semiconductor stocks led a broad market selloff on June 23, with the Nasdaq Composite falling 399 points to 25,766.67 by 10:48 a.m. Eastern time, while the S&P 500 declined 58.83 points to 7,413.96. The decline followed sharp losses in Asian memory chip markets and intensified as traders positioned ahead of Micron's fiscal third-quarter earnings report due June 24. The selloff reflected mounting pressure on artificial intelligence valuations after the Federal Reserve raised its year-end 2026 median federal funds rate projection to 3.8% at the June 17 FOMC meeting, up from 3.4% in March. The semiconductor sector sits at the center of the AI investment cycle, and the June 23 decline tested whether demand for AI infrastructure and memory chips can justify current valuations after a powerful multi-month rally.
Ishares Semiconductor ETF Falls 6% as Memory Chip Stocks Decline
The Ishares Semiconductor ETF fell about 6% on June 23, with several large chip names under heavy pressure. Micron dropped roughly 8% to 11% intraday, trading around $1,073 to $1,108 after closing Monday at $1,211.38 following an Anthropic supply deal. Intel fell about 7% to 8%, AMD declined about 6%, and Nvidia lost roughly 3%. The NYSE Composite fell 91.27 points to 23,504.95, while the Dow Jones Industrial Average rose 29.77 points to 51,742.48, helped by its lighter exposure to high-growth technology shares. The pressure followed Monday's tech-led weakness and intensified as a global semiconductor selloff spread through U.S. trading, with memory chip stocks hit hard after sharp declines in Asian markets, particularly among Korean memory names.
Fed Raises Year-End 2026 Rate Projection to 3.8%
At the June 17 Federal Open Market Committee meeting, the Fed held rates steady at a 3.50% to 3.75% target range, but policymakers raised their year-end 2026 median federal funds rate projection to 3.8%, up from 3.4% in March. New Fed Chair Kevin Warsh removed language that had previously pointed toward easier policy and declined to offer traditional forward guidance. His message emphasized inflation control, including a commitment to the Fed's 2% target after what he called years of misses. Higher rate expectations tend to weigh most on companies whose valuations depend on future earnings growth, a dynamic especially important for AI and semiconductor stocks where investors are pricing in years of expansion.
Bitcoin Trades at $62,451 as Digital Assets Weaken
The risk-off mood extended into digital assets during the same timeframe. Bitcoin stood at $62,451, up 0.30%, but down 3.71% over 24 hours and 4.88% over seven days. Ethereum traded at $1,661, up 0.34% over the last hour, but down 5.26% over 24 hours and 6.62% over seven days. Precious metals also weakened despite their traditional safe-haven role, with gold down about 1.4% near $4,145 per ounce and silver falling more than 4% toward the $62 area. The move reflected a mix of profit-taking, a stronger dollar, and yield pressure, and reduced immediate demand for geopolitical hedges as Middle East talks showed progress.
SpaceX Trades Above IPO Price After $75 Billion Public Offering
SpaceX, trading under SPCX after going public around June 12, remained volatile but showed relative resilience compared with pure-play chip names. The company priced its IPO at $135 per share, raised roughly $75 billion and entered public markets with an initial valuation above $1.75 trillion. The stock rallied after its debut, reaching above $160 intraday, before pulling back on dilution concerns tied to a $60 billion all-stock acquisition of AI coding startup Cursor. Tuesday's relative strength suggests investors are still separating some long-term growth narratives, including Starlink and Starship, from the immediate reset hitting memory and chip names.
Trump and Pezeshkian Sign 60-Day Diplomatic Framework on June 17
On June 17, President Trump and Iranian President Pezeshkian signed the Islamabad Memorandum of Understanding, launching a 60-day diplomatic process aimed at a final war-ending deal. The framework covers hostilities, Lebanon and Hezbollah, the Strait of Hormuz, oil sanctions and reconstruction issues. On Monday, technical talks in Switzerland produced what Vice President JD Vance called a "very, very good day," with Iran agreeing to allow International Atomic Energy Agency inspectors back, a de-confliction cell established to monitor the Lebanon ceasefire, and discussions continued over keeping the Strait of Hormuz open. On Tuesday, Pezeshkian traveled to Pakistan for follow-up talks with mediators from Qatar and Pakistan. Micron's June 24 report is the next major test for the AI trade, while the Fed's hawkish turn raises the bar for any quick rebound in risk assets.
