GoKawiilPolymarket Resumes Trading After Vendor Breach Drains Trader Wallets
Polymarket paused trading on its international platform after a UK-based third-party vendor was hacked, draining funds from user wallets. Blockchain analytics firm Bubblemaps estimated roughly 700 users lost about $2.7 million combined. Polymarket said it has notified UK law enforcement and will refund affected traders, but did not confirm the exact scale of losses; its separate, US-regulated Polymarket US platform was unaffected.
GoKawiil's interpretation of the reporting above, not reported fact.
The incident marks the second similar vendor-compromise attack on Polymarket since June, suggesting recurring weaknesses in third-party infrastructure that crypto platforms rely on rather than one-off failures. Coming the same day as a separate $2 billion theft from Binance, it underscores how exchanges and prediction markets remain exposed to supply-chain style attacks even when core platforms aren't directly breached. Repeated incidents could pressure Polymarket to tighten vendor oversight or face continued user distrust.
- A UK vendor breach, not Polymarket's own site, caused the wallet-draining hack.
- Roughly 700 users lost an estimated $2.7 million, per Bubblemaps; Polymarket has pledged refunds.
- This is the second nearly identical vendor-based attack on Polymarket since June.
