Polymarket Says Limit Buy Order Issue Nears Fix After Spam Mitigation

The prediction market platform said it reduced latency spam, fixed an "insufficient balance/allowance" error, and banned multiple ghost-fill account clusters as it works through remaining trading problems.

Summary

Polymarket said it has introduced measures to mitigate latency spam, a form of activity that can slow trading systems by flooding them with requests, and has fixed the platform error that showed "insufficient balance/allowance" for some users. The company also said another core issue affecting limit buy orders should be resolved in the coming days. In addition, it identified and banned multiple ghost-fill account clusters, indicating action against accounts linked to suspicious or manipulative order activity. The update suggests Polymarket is addressing both system performance and market integrity issues, with further updates expected within a week.
