Polymarket trading halted after vendor compromise; impacted users will be ‘made whole’

Predictions markets platform Polymarket was forced to halt trading on its international platform Thursday for nearly an hour because of what it said was a compromise of third-party software.

There were also unconfirmed reports from users on Polymarket’s Discord channel who said their wallets had been drained.

While Polymarket did not confirm that users had lost money, it said in an X post that “anyone who has been impacted will be made whole.”

“We’ll make this right and are fully reimbursing all affected traders,” the company said in a subsequent post on X.

Polymarket said the attack appeared to be emanating from the United Kingdom, and that it had referred the matter to British law enforcement authorities.

The hackers gained access to the funds via software from DebugBear, a web analytics and website performance tool, according to a person familiar with the details who was granted anonymity to address an evolving security situation.

DebugBear had said on X that it was experiencing an “ongoing security incident” at around 2 p.m. ET Thursday.

Crypto news website The Block reported that some $2.65 million in cryptocurrencies had been siphoned from Polymarket users’ wallets, citing data from blockchain analysis group Arkham.
