What is Parity?

Parity shows quoted price levels and visible sizes with the venue attached to each quote. Search for a market or trader, use venue and topic filters, and move between market context, trader views, trackers, activity and a dedicated multi-panel workspace. Volume, liquidity and recent price changes help frame the headline probability.

Global Polymarket and Polymarket US remain separate venue labels alongside Kalshi. Similar event wording does not prove identical contracts: compare resolution terms before interpreting a price difference. The displayed ladder represents available liquidity at that point, not a promise of a later fill. Portfolio navigation is available after sign-in, and account-specific trading permissions depend on the underlying venue connection.

Our take on Parity

The comparison is most useful when each price stays attached to its venue and visible order-book size. That context helps readers inspect a spread, but does not resolve unpublished platform costs or make global Polymarket and Polymarket US the same account or execution route.
