Coverage labels include Polymarket, Kalshi and Betfair, although the live platform counter can show fewer active feeds. Search by venue, topic and market attributes, then open the exact contract before comparing another site’s price. The pricing FAQ describes REST refreshes every 30–60 seconds. Pro WebSocket support is marked coming soon, and Enterprise stream availability depends on the contract. An extreme displayed gap can reflect stale data or mismatched contracts rather than an executable opportunity. ### Who it is for - Researchers searching several venues at once. - Users monitoring price changes and closing dates. - Developers building a lightweight API or MCP monitor. ## Features and coverage - **Search and watchlists** Filter aggregated markets by platform, topic and attributes, then keep selected markets together in a watchlist. - **Price-gap scanner** Inspect flagged cross-platform differences and direction labels; validate both contracts, fees and executable depth. - **Movers, calendar and resolved markets** Organize price changes, upcoming deadlines and completed contracts in specialized views. - **Whale and trader activity** Paid tools include a large-trade feed and trader leaderboard. - **Detailed market data** Review historical prices, open interest, liquidity and token fee rates in the deeper market views. - **API, MCP and Enterprise files** Choose daily request allowances by plan, or request historical arbitrage data, bulk files and custom delivery through Enterprise. ## Workflows with PredRadar ### Find a contract Search the event, narrow the venue and check the exact contract and closing date. ### Review a flagged gap Compare both rule sets, fees and executable depth.
