Built as a peer-to-peer marketplace with no centralized “house,” Polymarket aggregates diverse opinions into transparent, market-based probabilities that reflect collective expectations about the future. We're growing fast - both in terms of volume ($21B traded in 2025) and adoption as an alternative news source.
