United States.- 28 October 2026 | www.zonadeazar.com Prediction markets continue to expand as platforms for trading contracts linked to economic, political, financial and geopolitical events.
According to data published by market analysis platform The Rumpus in its 27 October 2026 edition, Kalshi and Polymarket collectively account for 762 active markets across 232 questions.
The figures highlight the diversity of tradable events and the growing interest in using contract prices as indicators of market expectations.
Kalshi Leads in Active Market Count
The data provides the following breakdown:
- Kalshi: 462 active markets.
- Polymarket: 300 active markets.
- Combined total: 762 markets.
- Available questions: 232.
Kalshi represents approximately 60.6% of the tracked markets, while Polymarket accounts for 39.4%.
These figures refer to markets included in The Rumpus monitoring system and do not necessarily represent every contract available on either platform.
Polymarket Records US$26.5 Million in Daily Trading Volume
Although Kalshi has more active markets within the dataset, Polymarket reports higher activity according to the figures displayed.
The latest 24-hour data shows:
- Polymarket: US$26.5 million in trading volume.
- Kalshi: 21.8 million contracts traded.
However, the two platforms use different reporting units.
Polymarket reports monetary trading volume, while Kalshi’s figures are expressed in contracts, meaning the values cannot be directly compared as equivalent financial volumes.
Federal Reserve Decisions Dominate Trading Activity
Among the most actively traded contracts are questions concerning monetary policy decisions by the US Federal Reserve.
On Polymarket, the contract assessing whether interest rates will remain unchanged following the October meeting shows:
- Implied probability: 94%.
- 24-hour trading volume: US$7.2 million.
A comparable Kalshi contract indicates a 93% probability, with approximately 2.2 million contracts traded.
The closely aligned figures suggest broadly similar expectations among participants on both platforms.
Geopolitics and Elections Drive Market Interest
Geopolitical developments also account for substantial trading activity.
One prominent market concerns whether Benjamin Netanyahu will become Israel’s next prime minister.
The figures show:
- Polymarket: 27% probability, with US$3.3 million traded.
- Kalshi: 26% probability, with 852,000 contracts traded.
The close alignment highlights similar pricing expectations across the two exchanges.
US Midterm Elections Attract Attention
The 2026 US midterm elections represent another important category within prediction markets.
Selected market probabilities recorded on 27 October include:
- Polymarket: 92% implied probability of Democrats controlling the House of Representatives.
- Kalshi: 10% probability of Republicans retaining control of the House.
- Polymarket: 66% probability of Democrats controlling the Senate.
- Kalshi: 36% probability of Republicans winning the Senate.
These figures represent prices associated with specific event contracts rather than election results or public opinion polling.
Bitcoin and Cryptocurrency Markets Remain Active
Digital assets also feature prominently among prediction market contracts.
Selected examples include:
- Bitcoin trading above US$78,000 on 27 October: 97% on Polymarket.
- Bitcoin reaching US$90,000 during October: 2% on Polymarket.

These contracts allow participants to trade expectations concerning price levels, deadlines and future cryptocurrency movements.
Differences Between Prediction Platforms
Kalshi and Polymarket offer contracts linked to many similar events, although their trading structures and reporting metrics differ.
Comparing both platforms can reveal differences in market expectations.
However, implied probabilities may vary because of differences in settlement rules, available liquidity and the timing of market updates.
Artificial Intelligence Supports Market Analysis
The Rumpus uses artificial intelligence models to produce content based on prediction market data and news reporting.
The platform organises contracts into categories including finance, cryptocurrency, US politics, geopolitics, technology and culture.
Its analytical approach aims to help readers interpret price movements, probability changes and differences between trading venues.
Industry Outlook
The 762 active markets identified in the dataset demonstrate the wide range of events currently available through prediction market contracts.
Monetary policy decisions, elections and international developments feature among the most prominent areas of interest.
The sector’s future development will depend on user participation, available liquidity and the regulatory frameworks governing different contract categories.
The figures also illustrate how prediction markets are expanding beyond sports-related products and gaining a broader role in economic, financial and political analysis.
