# Parity > Parity aggregates prediction markets across five venues - Polymarket, Kalshi, Polymarket US, Pascal, and Hyperliquid - so a trader can see and act on the best price for an event without checking each venue separately. Markets for the same real-world event are linked into curated cross-venue groups, showing the best tradeable spread (the cheapest ask and best bid across every venue that lists it) and combined 24-hour volume across all linked venues, alongside each venue's own price. All five venues - Polymarket, Kalshi, Polymarket US, Pascal, and Hyperliquid - are tradeable on Parity from one interface. Parity also surfaces orderbook insights: who's sitting at each price level in the book. Each venue charges its own fees; Parity adds none of its own. ## Site - [Home](https://predictparity.com/): Trending and featured markets across all five venues. - [Markets](https://predictparity.com/markets): Full market listing, searchable and filterable by venue, category, and status. - [Compare](https://predictparity.com/compare): Cross-venue price comparison - the same event priced on every venue that lists it, narrowed to markets with a curated link. - [Traders](https://predictparity.com/traders): Trader leaderboards and profiles. ## Docs: getting started - [Docs home](https://predictparity.com/docs.md): Parity aggregates Polymarket, Kalshi, Polymarket US, Pascal and Hyperliquid, with orderbook insights, trader tracking and cross-venue trading. - [Signup](https://predictparity.com/docs/getting-started/signup.md): How to sign up for Parity, with onboarding and wallets powered by Privy. - [Linking Accounts](https://predictparity.com/docs/getting-started/linking-accounts.md): Link your Polymarket wallet and connect Kalshi, Polymarket US, Pascal and Hyperliquid to trade them from Parity. - [Venues](https://predictparity.com/docs/getting-started/venues.md): The five prediction market venues Parity trades, Polymarket, Polymarket US, Kalshi, Pascal and Hyperliquid, and how they differ. - [Order Types](https://predictparity.com/docs/getting-started/order-types.md): Market and limit orders on Parity: how long they last and how they fill. - [Fee Schedule](https://predictparity.com/docs/getting-started/fees.md): Parity's fee schedule.
