Kalshi and Polymarket: The Rumpus Tracks 715 Prediction Markets
United States.- 30 October 2026 | www.zonadeazar.com The Rumpus, a platform specialising in prediction market analysis, provides a monitoring system bringing together data from Kalshi and Polymarket within a single interface.
In its 29 October 2026 edition, the website lists 715 active markets grouped into 205 questions, presenting information on probabilities, trading volumes and changes in market expectations.
The platform enables users to monitor trends across politics, finance, cryptocurrencies, geopolitics and technology, while comparing contract prices associated with similar events.
Kalshi Accounts for More Than 60% of Tracked Markets
According to The Rumpus, the 715 markets are distributed as follows:
- Kalshi: 441 active markets.
- Polymarket: 274 active markets.
- Total: 715 markets.
- Grouped questions: 205.
Kalshi accounts for approximately 61.7% of the markets included in the tracker, while Polymarket represents 38.3%.
These figures relate to contracts collected by The Rumpus and do not necessarily represent every product available on the two exchanges.
Trading Volumes Across Both Platforms
The dashboard also displays trading activity indicators for the previous 24 hours.
In the edition reviewed, The Rumpus reports:
- Polymarket: US$31.2 million in trading volume.
- Kalshi: 33.7 million contracts traded.
The distinction between these units is important: Polymarket’s volume is displayed in dollars, while Kalshi’s figure is denominated in contracts.
Consequently, the two figures should not be treated as directly comparable monetary amounts.
The tracker helps identify which events are attracting the greatest trading activity.
Comparing Market-Implied Probabilities
One of The Rumpus’s main features is the visualisation of probabilities implied by event contract prices.
The dashboard provides three viewing periods:
- One day.
- Seven days.
- One month.
Solid lines represent Polymarket data, while dashed lines indicate Kalshi prices.
The charts make it possible to identify changes in market expectations and differences between the two platforms.
The Rumpus notes that Kalshi’s charts may display stepped movements when no new trades have been recorded.
US Elections Attract Significant Attention
The dashboard highlights several questions relating to the 2026 United States midterm elections.
Tracked markets include:
- Control of the US Senate.
- The composition of the House of Representatives.
- State gubernatorial elections.
- Individual Senate races.
- Combined outcomes for both chambers of Congress.
These questions allow users to observe how traders price different potential outcomes.
The displayed probabilities reflect market prices at a particular moment and are neither official election results nor guarantees of future outcomes.
Kalshi Tracks Multiple Texas Election Markets
One of the featured groups concerns elections in Texas.
The Rumpus groups eleven markets relating to the state’s Senate contest and another ten concerning the gubernatorial election.
On 29 October, selected contracts showed:
- Texas Senate: a 33% implied probability for the featured Republican outcome.
- Texas governorship: a 65% implied probability for the highlighted Republican outcome.
These percentages reflect the market prices collected by the platform and may change as trading continues.
Grouping related contracts makes it easier to compare prices associated with the same electoral contest.
Geopolitical Events Also Feature Prominently
The dashboard includes international developments involving conflicts, elections and government decisions.
Featured questions cover political developments in Israel and scenarios involving international relations.
For example, The Rumpus tracks contracts concerning whether Benjamin Netanyahu will return as Israel’s prime minister.
In the edition reviewed, the dashboard showed differences between Kalshi and Polymarket prices for questions connected with that possibility.
Such differences may reflect contract settlement rules, liquidity and trading activity.
Finance, Cryptocurrencies and Technology
The platform also covers markets linked to financial indicators and digital assets.
Its principal categories include:
- Finance: Federal Reserve interest rate decisions and stock market movements.
- Cryptocurrencies: Bitcoin, Ethereum and other digital assets.
- Geopolitics: international conflicts and diplomatic developments.
- Technology and artificial intelligence: corporate developments and AI model performance.
- Culture: entertainment-related events and public figures.
This range enables users to examine market expectations across several sectors through one interface.
A Monitoring Tool for Industry Professionals
The Rumpus organises information by category and displays the top 100 questions ranked by trading volume over the previous 24 hours.
Its system also groups related contracts to support comparison.
The dashboard may be useful for researchers, specialist media and professionals monitoring the prediction market industry.
Users can track price movements, examine differences between platforms and identify events generating significant trading activity.
However, implied probabilities should be interpreted as market indicators rather than certainties about future events.
Industry Impact and Next Steps
The integration of Kalshi and Polymarket data within The Rumpus reflects growing demand for tools capable of analysing prediction market activity.
Access to hundreds of contracts through a single interface makes it easier to compare trends and identify differences between platforms.
The usefulness of these tools depends on data updates, individual contract liquidity and accurate interpretation of settlement conditions.
With 715 active markets grouped into 205 questions, The Rumpus provides a combined view of Kalshi and Polymarket, enabling users to monitor changing probabilities across a broad range of international events.
