The ReleaseLead
Blockratize Inc's Polymarket: Trade Soccer version 2.6.4, shipped on June 20, 2026, introduced critical in-app outages and glitches.[1] These failures prevented users from cashing out or trading during live sporting events, prompting direct financial losses and a severe user backlash.
Vague Release NotesRelease Summary
Official App Store release notes for v2.6.4 were generic, stating only that the app is "now CFTC regulated & legal in the United States" without mentioning technical changes. This lack of transparency obscures the cause of the subsequent stability issues.
The update was part of a rapid and potentially unstable development period. Version 2.6.1 was released on June 12, followed by v2.6.2 on June 16, just four days before v2.6.4. This frequent release cadence suggests an aggressive push for updates during the high-traffic World Cup period.

Trading BlackoutsBreaking Changes
The v2.6.4 update triggered a wave of new, critical complaints not seen in prior versions. Users reported catastrophic technical failures during live events, leading to financial losses. One 1-star reviewer on v2.6.4 stated, "their app crashed while i was trying to pull a live trade out and they wouldn’t refund me. I lost due to their engineering team what a waste."
Another user described a total blackout of the app during peak traffic, writing that the app "had yet another issue not allowing me to cashout a current bet I had and then for an hour was not able to edit or place any bets or existing bets a total blackout of the app during live matches of the World Cup." Others reported erroneous bet settlements, such as a postponed game resulting in a near-total loss instead of a refund.[2] One user claimed, "I paid $30 on the diamondbacks to win... the game got postponed... it gave me $2.95 in my account."

World Cup Stress TestRoot Cause
The technical failures appear linked to the immense traffic generated by the 2026 FIFA World Cup. Industry reports show Polymarket's World Cup contracts attracted an estimated $6.4 billion in wagers.[3] This was part of a sector-wide boom that saw prediction market volume jump 75% in June to nearly $45 billion. The massive influx of activity likely overwhelmed Polymarket's infrastructure, which was already showing signs of strain in prior updates.
Compounding the stability problems, Polymarket announced on June 25 that hackers compromised a third-party vendor, allowing them to steal funds from some user accounts. While a separate incident, it contributed to a wider narrative of platform unreliability at a critical time.

Trust ErodedExpert Verdict
With a user base of over 1.3 million downloads in the last 30 days on iOS in the US alone, the platform's instability affects a large audience. The combination of catastrophic technical failures and a concurrent security breach poses a significant risk to Polymarket's reputation. To regain user trust, the company will likely need to invest in stabilizing its infrastructure and communicating more transparently about the root causes of these issues. Without such measures, the platform risks losing traders to more reliable competitors, especially as it continues to grow.
