Stocks Surge After US-Iran Peace Agreement and SpaceX's Historic IPO

A US-Iran peace agreement sent shockwaves across global markets on June 15, 2026, lifting equities and fueling a broad rally in risk assets. President Trump announced late Sunday that the deal was "now complete," with Pakistan Prime Minister Shehbaz Sharif confirming an official signing ceremony scheduled for June 19 in Switzerland. The agreement includes an immediate end to military operations and the reopening of the Strait of Hormuz, the critical Persian Gulf shipping lane that handles roughly 20% of global oil trade . Energy stocks declined sharply as crude oil prices fell approximately 5%, while chip makers including Nvidia, Micron, and Intel led technology sector gains.

The Dow Jones Industrial Average advanced roughly 469 points, the S&P 500 climbed approximately 1.65%, and the Nasdaq Composite surged over 3%, according to market data for the session. Analysts noted that reduced Strait of Hormuz risk directly lowers shipping insurance premiums and eases near-term inflation pressure, two headwinds that had weighed on consumer discretionary and growth-oriented sectors for months. The agreement covers an initial memorandum that kicks off 60 days of formal negotiations on a final deal, including Iran's nuclear program, meaning market participants are pricing in diplomatic progress rather than a resolved conflict .

Investor sentiment received an additional boost from SpaceX's historic IPO, which debuted on Nasdaq under the ticker SPCX on June 12 and continued climbing in premarket trading Monday. The company raised approximately $75 billion in the largest public offering ever recorded, pricing shares at $135 and closing up 19% on its first trading day . The convergence of a geopolitical de-escalation and a once-in-a-generation equity market event drove broad risk appetite, with futures pointing higher before the open and institutional flows rotating into growth and technology.
