Trading has resumed on Polymarket’s flagship international platform after a hack that drained money from the wallets of some traders.
Key facts
- Polymarket recently raised $1 billion in August 2026, with a fundraising round led by 1789 Capital, the venture capital firm where Donald Trump Jr. is a partner
- On X, prominent traders complained that they had lost money; blockchain analytics firm Bubblemaps reported that around 700 users appeared to have been affected, with approximately $2.7 million stolen
- The company has been a lightning rod for controversy since its 2020 launch
- The hack did not impact users on Polymarket US, the company’s newer platform for people within the United States
Summary
A third-party vendor based in the United Kingdom was breached, not the prediction market ’s website itself. On X, prominent traders complained that they had lost money; blockchain analytics firm Bubblemaps reported that around 700 users appeared to have been affected, with approximately $2.7 million stolen. The hack did not impact users on Polymarket US, the company’s newer platform for people within the United States. This is not the first time that Polymarket traders have experienced security woes.
