Traders have bet on Polymarket, predicting a US-Iran ceasefire by March 31 or April 15. They've wagered around $160,000 on ceasefire, and if it happens, they could win $1 million, WION reported. Reportedly, one account that placed the ceasefire bet had also placed winning bets on US-Israel striking Iran on February 28. That account was created just before war's start.
