US Stock Market Today: Micron Earnings Set to Test AI Rally Momentum as S&P 500 Nears Records

Wall Street investors will turn their attention to Micron Technology’s quarterly earnings next week for fresh evidence on semiconductor demand and artificial intelligence spending.

The memory chipmaker will report on Wednesday, June 24. Its results will arrive as major US stock indexes trade near record levels following a technology-led rebound ahead of the Juneteenth holiday.

Micron Earnings Put Chip Demand in Focus

Micron shares have gained 298% this year as demand for memory chips used in data centres has grown. Investors will examine its revenue, profit forecast, and customer orders for signs that spending on AI infrastructure is still rising.

The company’s report may also show whether chip supply can meet demand from technology companies. Steve Kolano, Chief Investment Officer at Integrated Partners, said semiconductor order books and backlogs suggest demand is running well above available capacity. Still, investors are questioning how long that gap can support chip prices and earnings.

AI Spending Supports Wall Street Rally

Large technology companies have indicated that AI investment will exceed $700 billion this year, up from about $400 billion in 2025. That spending has supported suppliers of processors, memory products, networking equipment, and data-centre systems.

Meanwhile, the Philadelphia Semiconductor Index reached a record and gained about 7% for the week. The S&P 500 also advanced nearly 1%, helped by chip shares and Apple’s agreement to work with Intel on designing and manufacturing semiconductors in the United States.

Investors Question Whether Gains Can Last

Strong earnings and AI investment have kept the S&P 500 and NASDAQ Composite close to record highs. Nevertheless, high company valuations have raised questions about whether future earnings can match current market expectations.

Andy Pratt, director of investment strategy at Burney Company, said the AI trend still has momentum. He added that revenue data showed “there’s still a lot of juice.” His comments reflected current demand, although Micron’s report will provide a clearer measure of recent memory-chip orders.

The market ended the holiday-shortened week higher after recovering from a Federal Reserve-led selloff. On Thursday, the S&P 500 rose 1.08% to 7,500.58, while the NASDAQ Composite gained 1.91% to 26,517.93. The Dow added 72.15 points to close at 51,564.70.

Inflation and GDP Reports Add Economic Test

Investors will also receive the Federal Reserve’s preferred inflation measure and a final reading of first-quarter US gross domestic product next week. The reports will offer updated information on consumer prices, household demand, and economic growth.

S&P 500 earnings are expected to rise 22.9% in the second quarter, compared with 29.3% in the first quarter. Drew Matus of MetLife Investment Management said rising stock values have supported consumer finances. He questioned what could happen “if the wealth effect goes away” following any market decline.

US Markets Reopen After Juneteenth Closure

The New York Stock Exchange and NASDAQ are closed on Friday, June 19, for the Juneteenth federal holiday. Regular stock trading will resume on Monday, June 22.

Global markets traded without a clear direction on Friday as investors assessed the durability of the US-Iran peace agreement. Lower geopolitical tension and the reopening of the Strait of Hormuz have supported US equities, although investors are still watching whether both sides follow the agreement’s conditions.
