Polymarket temporarily halted trading on its international platform after identifying that a third‑party provider had been compromised, and trading resumed later the same day. The company said it has referred the incident to law enforcement in the United Kingdom and will make any affected traders whole.
The platform’s status page indicated that systems were fully operational by the evening, and Polymarket confirmed that the breach did not affect its US‑based platform. The company pledged to fully reimburse traders who were impacted by the security incident.
