Polymarket user AdrianCronauer hacked for over $2 million
A Polymarket user identified as AdrianCronauer was hacked and lost over $2 million in funds, according to a tweet from community member Cajetan reported by Foresight News on June 1. The incident highlights security risks for traders holding large balances on crypto-native prediction market platforms where users self-custody funds through wallet connections. No details on how the hack was executed or whether funds are recoverable were included in the report. In a separate incident, a Hacker News user claimed in a post on Monday, June 2 that they were scammed for $500,000 on Polymarket, asserting the industry is 'full of immoral douches who think they are above being regulated,' though that post lacked details on how the alleged scam occurred or whether any party was responsible.
The AdrianCronauer theft puts Polymarket's self-custody model under direct scrutiny as traders weigh whether to keep six-figure balances on a platform with no apparent recovery mechanism. Any platform response — or silence — will shape whether rival operators treat this as a competitive opening to push custody alternatives.
Second major Polymarket security breach in under a week, after the $700,000 POL drain, deepening the platform's exposure across seven concurrent federal and journalistic probes into wallet exploitation and oracle integrity failures.
