Polymarket
Polymarket operates as a prediction market platform. In August 2026, it was reported that Polymarket, along with Kalshi, collectively accounted for 93% of the prediction market volume. This development coincided with the shutdown announcements from two other prediction market platforms, Trepa and Fireplace, which instructed users to withdraw funds by September 30. One of the closing platforms suggested the active user base for crypto was smaller than reported.
Overview
Polymarket operates as a prediction market platform. In August 2026, it was reported that Polymarket, along with Kalshi, collectively accounted for 93% of the prediction market volume.

One of the closing platforms suggested the active user base for crypto was smaller than reported.
Recent developments
In August 2026, Polymarket was identified as one of two platforms, alongside Kalshi, that together accounted for 93% of prediction market volume. This occurred as two other prediction markets, Trepa and Fireplace, announced their shutdown.
Historical context
The August 2026 news coverage indicates Polymarket's prominence in the prediction market sector, particularly as other platforms ceased operations.
History
Polymarket recently upgraded its crypto up/down markets, offering $1 million in rewards. This development followed a security incident where a five-second trick allowed traders to drain millions from the platform, despite public warnings from onchain analysts.
Risk factors
A lawsuit for $170,000 over a prediction bet poses a risk to Polymarket, potentially redefining legal accountability in prediction markets and impacting user trust in dispute resolutions.
Technology
Polymarket is moving to time-weighted prices to make artificial price pushes too costly. This change is part of an upgrade to its crypto up/down markets, designed to reduce manipulation risks.
Outlook
Will Polymarket maintain its significant share of prediction market volume? How will its position be affected by the exit of other platforms from the market?
