Stock Market Today: Dow set for 500-point drop, S&P 500 and Nasdaq to decline as oil prices jump on threat of war resuming in Iran

Investors stand to lose as the Dow Jones Industrial Average is projected to drop around 500 points, while the S&P 500 and Nasdaq are also expected to fall. Such a slide would erode gains built over the past year, pressuring portfolios, retirement accounts and triggering stop‑loss orders across major equity funds. Benzinga reported that futures for the Dow and S&P 500 moved lower as the Pentagon readied for a potential strike, and Seeking Alpha linked the decline to oil prices rising after prospects for an Iran nuclear deal faded.

Fortune noted that Trump’s focus on a new round of combat operations in Iran amplified the sell‑off, while MarketWatch highlighted the oil price jump tied to the threat of renewed conflict. Yahoo Finance posed the question of whether the S&P 500 would open up or down, reflecting the market’s heightened uncertainty. Coverage does not yet specify when or if any strike will occur, nor does it confirm how long oil prices will stay elevated, leaving the depth of the market decline uncertain.

Analysts note that if the geopolitical tension eases, the oil rally could recede, but the brief offers no timetable for such a shift. Consequently, the immediate risk to equity valuations remains tied to unresolved war‑related developments.
