Kalshi and Polymarket Surpass 23,000 Active Prediction Markets
United States.- 14 October 2026 | www.zonadeazar.com Financial analytics platform Frenzy Capital has updated its prediction markets monitoring tool, bringing together information from Kalshi and Polymarket covering economic, political, sporting and technological events.
Data reviewed on 13 October 2026 showed approximately 23,000 active markets across both platforms, with tens of millions of dollars traded over the previous 24 hours.
The tool allows users to analyse probabilities, price movements, trading volumes and large transactions, providing a combined overview of prediction market activity.
More Than 23,000 Active Markets
Frenzy Capital’s dashboard tracks approximately 23,000 active contracts, covering more than 4,500 different events.
The distribution between platforms is relatively balanced:
- Kalshi: more than 11,000 markets.
- Polymarket: approximately 11,000 markets.
- Available events: more than 4,500.
These contracts cover monetary policy decisions, sporting results, technology launches and international developments.
Sports Account for the Largest Trading Volume
One of the most significant findings is the dominance of sporting events within prediction markets.
According to Frenzy Capital, approximately 75% of total trading volume comes from sports-related contracts.
In one dashboard update, sports trading reached approximately $102 million over 24 hours, compared with $34.2 million across non-sporting categories.
This distribution highlights the importance of sports within an industry that also offers contracts linked to economic, political and technological developments.
Main Prediction Market Categories
Frenzy Capital organises its contracts into several categories to facilitate monitoring and analysis.
The principal segments include:
- Politics and elections: electoral outcomes and government developments.
- Economy and Federal Reserve: interest rates, inflation and macroeconomic indicators.
- Cryptocurrencies: Bitcoin prices and other digital assets.
- Companies and financial markets: initial public offerings and corporate developments.
- Technology and artificial intelligence: product launches and technological innovation.
- Sports: match results, championships and international competitions.
The platform also covers weather, entertainment, culture and global events.
US Elections Among the Most Traded Markets
Contracts linked to the 2026 US congressional elections rank among the most actively traded non-sporting markets.
During the reporting period, the market concerning control of the House of Representatives generated approximately $1.8 million in trading volume over 24 hours.
Other actively traded contracts included those concerning the balance of power in Congress and potential candidates for the 2028 presidential election.
These figures represent market trading activity rather than confirmed electoral outcomes or guarantees of future events.
Federal Reserve Decisions Attract Trading Activity
US monetary policy decisions also account for a substantial proportion of trading activity.
Contracts concerning the Federal Reserve’s October 2026 meeting ranked among the most actively traded economic events.
During the reviewed update, market prices implied approximately an 80% probability that the Federal Reserve would leave interest rates unchanged.
These probabilities reflect prices established through market transactions and may change rapidly in response to new economic information.
Monitoring Large Transactions
One of Frenzy Capital’s features identifies significant capital movements within Kalshi.
The tool tracks orders exceeding $1,000, displaying their direction, size and concentration across individual contracts.
Among the notable examples were aggregated transactions exceeding $700,000 in a market linked to control of the US House of Representatives.
The system uses publicly available anonymous trading data, allowing users to examine order flows without identifying individual traders.
Tracking Probabilities and Price Movements
The dashboard also highlights contracts experiencing the largest probability changes over the previous 24 hours.
To reduce distortions, the system prioritises markets with at least $5,000 in trading volume and excludes certain contracts approaching settlement.
In prediction markets, contract prices are commonly interpreted as implied probabilities.
For example, a contract trading at $0.62 represents an implied probability of approximately 62% for the corresponding outcome.
However, these prices reflect market expectations rather than verified forecasts.
Differences Between Kalshi and Polymarket
Although both platforms allow participants to trade contracts linked to future events, their operating models differ.
Kalshi operates as a US exchange regulated by the Commodity Futures Trading Commission (CFTC).
Polymarket, meanwhile, developed as an international platform using blockchain infrastructure and cryptocurrency-based settlement.
Frenzy Capital aggregates information from both sources, allowing users to compare market activity and probabilities across their respective platforms.
Next Steps and Impact
Data compiled by Frenzy Capital demonstrates the scale reached by prediction markets, with more than 23,000 active contracts and sports accounting for the majority of trading activity.
The expansion of these platforms is accompanied by growing interest in analytical tools capable of tracking prices, liquidity, probabilities and significant capital movements.
Combining information from Kalshi and Polymarket provides greater visibility into trading patterns and the events attracting market participation.
As the industry expands internationally, independent analytical platforms could become increasingly important for understanding price discovery and the distribution of trading volumes.
