The S&P 500 edged marginally lower at Tuesday's market open, slipping 2.39 points, or 0.03%, to 7,438.04, following a robust 1.18% gain in the previous session. Monday's rally had been fueled by easing geopolitical tensions and a sharp rebound in semiconductor stocks, which together lifted risk appetite across markets.

Monday's Session Performance

Monday's broad-based rally saw the S&P 500 close at 7,440.43, with the Dow Jones Industrial Average closing above the 52,000 level for the first time. The gains were underpinned by an agreement between the U.S. and Iran to halt hostilities and allow commercial vessels to move freely through the Strait of Hormuz, easing concerns over potential energy supply disruptions. Semiconductor stocks staged a sharp rebound, with the VanEck Semiconductor ETF climbing more than 3%, while Alphabet gained nearly 5% in its debut as a Dow component.

Market Outlook and Key Data

Polymarket's June 30 contract had implied a 61% probability that the S&P 500 would open higher on Tuesday, though betting remained volatile throughout Monday's session. The previous day's Polymarket bet resolved "Up" as the S&P 500 opened at 7,391.88, above Friday's close of 7,354.02. Investors continue to balance optimism over easing geopolitical risks with lingering concerns about the sustainability of artificial intelligence spending. Market participants are monitoring May's JOLTS job openings report, June's Chicago PMI, and consumer confidence data for fresh clues on the strength of the U.S. economy.
