Polymarket Says Ghost Fills Dropped to 0.17% After Deposit Wallets Launch

Polymarket said dedicated Deposit Wallets for new users cut ghost fills from a 30% peak to 0.17%, while the platform continues addressing stability, balance, PnL, and reward-tracking issues.

Summary

Polymarket said its Deposit Wallets rollout for newly registered users has significantly reduced ghost fills, with the rate falling from a peak of 30% to 0.17% after launch. The feature gives each eligible account a dedicated deposit address and was previously scheduled for May 4 at 12:30 UTC. Josh Stevens, Polymarket’s new Vice President of Engineering, said on X that the ghost-fill rate should continue trending toward 0% through the day. Polymarket also said it distributed the remaining liquidity rewards from April 28, restored reward accrual after an interruption of about 40 minutes, and is still working on fixes for balance errors and PnL display issues.
