What happened
Trepa and Fireplace asked users to withdraw funds by September 30 amid 93% volume concentration at Kalshi and Polymarket.
Why it matters
Two closures within hours highlight the vulnerability of smaller markets against the backdrop of high volume concentration at Kalshi and Polymarket.
Trepa and Fireplace notified users of the need to withdraw funds by September 30. According to The Defiant, both markets announced the cessation of operations within hours of each other.
Kalshi and Polymarket account for 93% of the prediction market volume, according to the source's headline and synopsis. One of the closing projects also published an analysis claiming that the active user base of the crypto market is significantly smaller than industry estimates.
For the sector, this implies increased attention on liquidity concentration and the actual number of active users. However, available materials are limited to metadata and The Defiant's synopsis, meaning details regarding the closures and the methodology for calculating the volume share require verification.
