S&P 500 and oil futures spike minutes before Trump halts strikes on Iran, triggering market moves.

Early Monday, S&P 500 e-Mini futures and West Texas Intermediate oil futures saw sharp volume spikes around 6:50 a.m. in New York, just before President Trump announced on Truth Social that planned U.S. strikes on Iranian energy infrastructure were halted following talks with Iran. This announcement caused S&P 500 futures to rally over 2.5% and oil futures to drop nearly 6%. The unusual early trading volume raised questions about possible insider moves or algorithmic trading, but no official comment was made by regulators. This event highlights how geopolitical news can swiftly impact markets, especially in thinly traded premarket hours.
