S&P 500 Index futures fell 0.2% as of 7:47 a.m. in New York, reflecting investor caution after the US intensified strikes against Iran. The military action targeted an oil tanker near the Islamic Republic's main export terminal, marking the first such strike since the renewed blockade of Iranian ports.

Geopolitical tensions escalated as the strike signals a more aggressive posture in the ongoing confrontation. Markets are assessing potential impacts on global oil supply routes and broader risk sentiment.

Major premarket movers include AtaiBeckley, GE Aerospace, and UnitedHealth, though specific price action wasn't detailed. Traders are monitoring developments for further direction.
