I agree; exact day was predictable enough for people to place confident-enough bets on. Notices to evacuate non-essential personnel from US military bases, embassies, & consulates in the region also went out 1-2 days prior to Israel's strikes on Iran on June 13, 2025.

My social circle had largely expected that Iran was getting bombed on Saturday or Sunday once the evacuation notices went out Friday, and this intuition was merely from laymen who follow the news. I don't doubt that insider trading was involved as it's the norm with this Admin, but I also don't doubt that many savvy people could've legally placed successful bets.
