Polymarket draws attention after removing nuclear weapon explosion prediction market

Polymarket has removed its long-term market that allowed users to bet on the possibility of a nuclear weapon explosion. This move comes amid the current conflict with Iran and has attracted attention due to criticism over war-related insider trading. These nuclear explosion prediction contracts once implied risks as high as 19%, with trading volumes reaching several millions of dollars, raising concerns about profiting from insider trading. Meanwhile, the U.S. Commodity Futures Trading Commission is considering banning regulated exchanges from listing event contracts related to war, terrorism, assassination, and similar activities.
