Prediction 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.
Key facts
- Polymarket was valued at $21 billion in September after a group of investors led by Donald Trump Jr. invested $1 billion in the platform
- Crypto news website that some $2.65 million in cryptocurrencies had been siphoned from Polymarket users’ wallets, citing data from blockchain analysis group Arkham

- DebugBear said on X that it was experiencing an “ongoing security incident” at around 2 p.m
Summary
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 on X post “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 emanate from the United Kingdom and that it had referred the matter to British law enforcement authorities.
