It is actively being worked on and improved, but may be unreliable. Polymarket and Kalshi data are live. At least for the time being, this endpoint requires a Growth or Enterprise plan.

It's useful for comparing market performance, identifying trending markets, and analyzing multi-market events. Key characteristics: * **Event ID format**: The `eventId` format varies by platform: * **Polymarket**: `:Polymarket::` (e.g., `67284:Polymarket:0xc5d563a36ae78145c45a50134d48a1215220f80a:137`) * **Kalshi**: `:Kalshi` (e.g., `KXMVESPORTSMULTIGAMEEXTENDED-S2026350C4EF9BCE:Kalshi`) * **Batch market data**: Get bars for up to 10 markets in a single query * **Flexible ranking**: Rank markets by volume, liquidity, trending score, or outcome-specific metrics * **Complete market context**: Each response includes the full market object plus bar data * **Efficient querying**: Better performance than making multiple individual [`predictionMarketBars`](/api-reference/queries/predictionmarketbars) calls * **Time-series format**: Same OHLC bar structure as [`predictionMarketBars`](/api-reference/queries/predictionmarketbars) Common use cases: * Display multiple markets from an event on a dashboard * Compare trading activity across related markets * Identify the most active or trending markets within an event * Build event overview pages with market-level granularity ## Troubleshooting Tips * Use `rankBy` for market-level metrics (e.g., `volumeUsd24h`, `liquidityUsd`, `uniqueTraders24h`) * Use `rankByOutcome` + `rankByOutcomeAttribute` for outcome-specific metrics (e.g., price changes, outcome-specific volume) You cannot use both at the same time. Choose based on whether you're ranking markets by overall activity or by specific outcome performance. When you provide `marketIds`, the ranking parameters are ignored and you'll get bars for exactly those markets. This is useful when you want specific markets but still benefit from the batch query performance. The limit parameter is also ignored in this case. Possible reasons: * The event has fewer markets than your limit * Some markets had no activity in the specified time range (when `removeEmptyBars: true`) * Some markets don't have the ranking attribute you specified (e.g., older markets may not have trending scores) Check the total number of markets in the event using the `predictionEvent` query. Trending scores (e.g., `trendingScore1h`, `trendingScore24h`) are composite metrics that consider: * Recent volume changes * Price movement velocity * Unique trader growth * Social engagement (where available) Higher scores indicate markets experiencing rapid increases in activity. Use these to surface "hot" markets. * `DESC` (descending): Highest values first - use for "top" markets (e.g., highest volume, most liquid) * `ASC` (ascending): Lowest values first - use for "bottom" markets or when looking for lowest spreads, earliest closing times, etc. Most use cases want `DESC` to get the top/best markets. Yes! The ranking only determines which markets are returned. You can rank by `outcome0.priceChange1h` but still query full data for both `outcome0` and `outcome1` in your bars selection. The ranking criterion doesn't limit what data you receive. The 10-market limit balances comprehensive data with performance. If you need more markets: * Make multiple queries with different ranking criteria * Use pagination by explicitly specifying different `marketIds` in subsequent queries * Consider whether you truly need more than 10 markets for your UI/analysis Most dashboards and visualizations work well with 5-10 top markets. ### Related Recipes * [Prediction Event Dashboard](/recipes/predictions/event-dashboard): Use multi-market bars for the probability comparison chart on an event page * [Prediction Charts](/recipes/predictions/charts): Render multi-candidate probability lines and other chart types
