The S&P 500 surged 1.65% to close at 7,554.29 on Monday, marking its strongest daily gain in weeks, as President Donald Trump announced a deal to end the war between the U.S. and Iran. The rally was driven by falling oil prices and easing geopolitical tensions, though Polymarket traders remain divided on whether the benchmark index can extend its gains at Tuesday's open. The June 16 Polymarket contract implied a 52% probability that the index will open higher, reflecting an almost even split among traders.
Why That Number Matters
Markets rallied after Trump announced that the U.S. and Iran had reached an agreement to end the conflict in the Middle East. According to Pakistani Prime Minister Shehbaz Sharif, both sides have agreed to terminate military operations, with a formal signing ceremony scheduled for Friday in Switzerland. The agreement is expected to reopen the Strait of Hormuz on Friday, helping drive oil prices nearly 5% lower on Monday and easing inflation concerns ahead of this week's Federal Reserve meeting.
Market Snapshot
The following table summarises the S&P 500's closing performance for the session:

| Percentage Change: | +1.65% |
| Session: | Close |
The Bull Case
The prospect of a lasting peace agreement has improved the outlook for energy prices, inflation and economic growth. Monday's rally was broad-based, with the Dow Jones Industrial Average reaching a new record close while the Nasdaq posted its best day since March 31. SpaceX (NASDAQ: SPCX) shares also gained nearly 20%, extending the strong momentum from Friday's historic IPO debut. However, S&P 500 futures trading was largely flat overnight, suggesting traders are waiting for additional confirmation that the Iran agreement will proceed as planned and that the reopening of the Strait of Hormuz occurs without disruption.
How will the Federal Reserve adjust its interest rate strategy this week given the sudden drop in oil prices and inflation concerns?
What are the potential risks to the S&P 500's rally if the formal signing ceremony on Friday faces delays or disruptions?
Will the reopening of the Strait of Hormuz lead to sustained lower energy prices, or could supply chain disruptions offset the benefits?
