List of Prediction Markets in 2025

featured image

By late 2025, prediction markets have evolved from niche experiments into one of the world’s most effective forecasting tools. No longer just for crypto natives, these markets have exploded into the mainstream, with major financial apps now offering direct access to event contracts.

This guide provides an updated list of the most relevant prediction markets in 2025. It includes regulated platforms like Kalshi, leading decentralized prediction markets such as Polymarket and Myriad, and community-driven forecasting sites like Manifold. These platforms represent the core ecosystem for anyone analyzing or trading event-based probabilities.

To learn more about how prediction data powers modern applications, see our overview of the FinFeedAPI infrastructure in the article Introducing Prediction Markets API.

At their core, prediction markets are exchange platforms where users trade the outcome of future events. Unlike a poll, participants put "money where their mouth is."

How do prediction markets work? You buy shares in an outcome (e.g., "Yes, X will happen"). The price of that share (between $0.00 and $1.00) represents the market's estimated probability of the event occurring.

Settlement: If the event happens, the share pays out $1.00. If it doesn't, it expires at $0.00.

The Goal: To harness the "wisdom of the crowd" for accurate, real-time forecasting of elections, economic shifts, and sports results.

For a deeper overview of how forecasting markets function and why they outperform polls, see our Prediction Markets Guide.

Prediction markets have evolved from academic theory to regulated financial instruments. Their conceptual roots trace back to the Iowa Electronic Markets (IEM) in the late 1980s, which demonstrated the remarkable accuracy of market-based probability pricing, often outperforming traditional polling and expert analysis.

The early 2000s saw the rise of political-focused platforms like PredictIt (operating under academic exemptions) and the conceptual groundwork for decentralized mechanisms like Augur. However, the modern revolution began with crypto-native platforms (Polymarket), which introduced global, 24/7 liquidity and permissionless market creation.

The final major shift occurred with the advent of CFTC-regulated exchanges (Kalshi), marking the industry's formal convergence with traditional finance by providing the regulated, institutional infrastructure (like the FIX API) required by high-frequency trading and quantitative firms today.

These are the primary platforms shaping the prediction markets landscape in 2025. They also represent key integrations for prediction market APIs, making them central to analytics and forecasting tools.

Kalshi is the only CFTC-regulated prediction exchange in the United States. It operates as a compliant financial marketplace where users can trade real-money event contracts on macroeconomic indicators, government policy decisions, climate events, and political outcomes.

Key traits:

  • Regulated and fully legal in the U.S.
  • Institutional-grade liquidity
  • API support for quant and algorithmic trading
  • Markets covering inflation, interest rates, jobs data, elections, and more

Kalshi is widely used by hedge funds, analysts, and financial professionals seeking exposure to verifiable, real-world outcomes under a strict regulatory framework.

Polymarket is the leading decentralized prediction market, serving as the primary source of real-time probabilities for a wide range of global, crypto, and cultural events. Its on-chain infrastructure is uniquely suited for quant researchers, arbitrageurs, and developers building decentralized trading bots.

Key traits:

  • Deep liquidity in non-sports markets
  • Transparent order books and on-chain settlement
  • UMA oracle-based resolution
  • Global access, with U.S. trading restrictions

Polymarket is a central source of live probability signals and is often referenced in the media as an indicator of public sentiment.

Myriad represents the next generation of decentralized prediction markets, designed explicitly for developers, quant researchers, and platforms that require data composability and cross-app integration. Its focus is less on volume and more on technical flexibility and becoming a foundational layer for other applications.

Key traits:

  • Designed for integration into apps, dashboards, and forecasting models
  • Customizable markets across multiple categories
  • Focus on clean, standardized data for analysis and automation
  • Rapid growth across 2024–2025

Myriad emphasizes technical flexibility and serves as an infrastructure layer as much as a standalone prediction market.

Manifold uses a virtual currency called Mana rather than real money, but it remains one of the most active and diverse prediction ecosystems in the world. Users can create markets on virtually any topic, making it a valuable environment for sentiment analysis and research.

Key traits:

  • Massive forecasting community
  • Quick settlement and constant market creation
  • Suitable for researchers and model training
  • Option to donate Mana-equivalent earnings to charity

Manifold is widely used for idea exploration, early-signal analysis, and experimental forecasting.

Beyond the major exchanges, this group of platforms caters to developers and quant firms by offering specialized infrastructure, unique collateral pools, and early arbitrage opportunities across emerging blockchain ecosystems.

A Polygon-, Ethereum-, and Moonbeam-based platform using an AMM design. Supports USDT and offers continuous liquidity for real-world event markets.

A prediction module within the Drift Protocol DEX. Supports over 30 collateral types, including yield-bearing assets, making it a flexible tool for traders on Solana.

A Base-based prediction platform where users can create and trade markets on crypto, tech, and sports. Growing rapidly with increasing weekly activity.

A decentralized prediction market built on Kusama and using the ZTG token. Designed for governance-related forecasting and experimentation.

A blockchain optimized for prediction markets and betting. Provides fully on-chain settlement and supports both market creation and peer-to-peer trading.

A Solana-native prediction market offering peer-to-peer markets, AMM pools, and parimutuel markets. Includes pooled staking products for more advanced strategies.

Infrastructure protocols power prediction markets rather than serving as consumer platforms. These systems support liquidity sharing, market creation, and on-chain settlement for multiple applications.

A modular liquidity engine using the Liquidity Tree model. Enables fast development of prediction apps and allows multiple frontends to share liquidity efficiently.

A non-custodial protocol powering sports markets with shared liquidity. Uses off-chain cranking to ensure fair settlement, particularly during real-time, in-play events.

This summary helps evaluate the main platforms across key dimensions.

When evaluating prediction markets in 2025, consider:

  • Regulation vs decentralization
  • Market categories available
  • Liquidity depth and market volume
  • Collateral type and on-chain fees
  • Oracle quality and resolution rules
  • Whether the platform supports early exit or only final settlement
  • User interface and ease of trading

Professional traders may prefer Kalshi and Polymarket, while forecasters and researchers often gravitate toward Manifold or Myriad for experimentation and breadth.
