Polymarket v2.5.9 Fixes Widespread Withdrawal Holds, Doubling App Rating in June 2026

While official release notes for v2.5.9 are unavailable, the update follows a turbulent period for the prediction market app. The previous version, 2.5.8, was plagued by reports of users being unable to access their funds. The timing of the v2.5.9 release and the subsequent shift in user feedback strongly suggest it contained backend fixes targeting payment blockages.

This update came after a major "V2" platform overhaul in April 2026, which introduced a new trading engine. The publisher had also announced measures in May to address "insufficient balance/authorization" errors, indicating a focus on platform integrity ahead of the June release.

The contrast in user feedback before and after v2.5.9 is sharp. Reviews for prior versions were dominated by severe financial complaints, with users accusing the app of being a scam. "When you deposit money and win, you won’t be able to withdraw!!" wrote one 1-star reviewer on v2.5.8. Another user on a 5-star review later edited to be negative stated, "They put a hold on my account and I can't get in touch with a real person to take it off."

After the v2.5.9 update, these specific complaints about frozen funds largely disappeared from new reviews, and the app's average ratingGlossaryStar RatingThe 1-5 star a^[1]verage users give your app on the App Store and Google Play — a primary ranking signal and one of the biggest conversion drivers on your product page. climbed from 1.52 to 2.94 stars. This indicates the primary issue was resolved for many users.

Although the critical withdrawal issue appears fixed, new problems have surfaced. Post-update reviews now focus on platform instability and payment processing failures. One 1-star review for v2.5.9 asks, "how the actual f… is BOA and Capital One not accepted?" Another user reported losing money because the app frequently goes down for maintenance, stating, "I have lost hundreds because the app goes down so often and you can’t cash out or buy more."

These new complaints suggest that while the most urgent problem was solved, the platform's infrastructure, particularly after its April "V2" overhaul, struggles to handle high traffic and faces challenges with payment gateways.

The new stability issues were particularly acute during the 2026 World Cup, a period of intense trading. User complaints about "Intentional maintenances in the middle of World Cup" align with external reports of outages on the platform during the event's opening days. The high trading volume, which saw one trader lose $4.2 million, likely strained Polymarket's systems. The card rejection issues point to a different challenge: the ambiguous regulatory status of prediction markets. Some banks are reportedly applying stricter rules for platforms like Polymarket, which can trigger transaction blocks as they navigate a gray area between finance and gambling.

With over 731,000 downloads in the past month, Polymarket serves a large audience engaged in high-stakes trading. By fixing its withdrawal failures, Blockratize Inc. has likely prevented a complete collapse of user trust. However, the platform's recovery is fragile. The new issues with stability and payment processing show that the technical and regulatory challenges are far from over. Future updates will need to address infrastructure scalability and navigate the complex relationship with financial institutions to maintain this positive momentum.
