Polymarket saw $529M traded on bets tied to bombing of Iran | TechCrunch

"$529 million was traded on contracts tied to the timing of the attack, according to Bloomberg. An analysis by analytics firm Bubblemaps SA found that six newly-created accounts made a profit of $1 million by correctly betting that the U.S. would strike Iran by February 28 - behavior that could indicate insider trading."

"The circulation of information "involving war or conflict," coupled with Polymarket's anonymity, "can create incentives for informed participants to act early." This assessment from Bubblemaps CEO Nicolas Vaiman highlights structural vulnerabilities in prediction markets handling sensitive geopolitical events."

"We don't list markets directly tied to death. When there are markets where potential outcomes involve death, we design the rules to prevent people from profiting from death. He added that Kalshi would reimburse all fees from these bets."
