In recent years, prediction markets operating at the intersection of digital finance and crypto have attracted growing attention from both individual users and institutional players. One of the most prominent examples in this space is Polymarket, which stands out with its yes/no markets covering elections, macroeconomic trends, and global events.
As Polymarket gained visibility, questions such as “Which companies are similar to Polymarket?”, “Are these platforms legal?” and “How are they different from traditional betting?” became increasingly common. The reason is simple: not all prediction market platforms operate under the same structure. Some function as regulated event contract exchanges, while others rely entirely on crypto and DeFi-based infrastructures. A third group sits somewhere between betting exchanges and forecasting platforms.
This guide examines companies and projects similar to Polymarket through the lenses of regulation, technology, liquidity models, and user profiles, offering a clear overview of the prediction market landscape.
What Is Polymarket and How Does It Work?
Polymarket is a prediction market platform where users trade event contracts tied to real-world outcomes. These contracts are typically structured in a Yes / No format, and their prices reflect the market’s collective estimate of the probability of an event occurring.
The event contract model
Each market consists of two opposing contracts:
-
Yes: Pays out $1 if the event occurs.
-
No: Pays out $1 if the event does not occur.
If a contract trades at $0.63, the market is effectively pricing the probability of that event at 63%. Once the outcome is finalized, the correct contract settles at $1, while the incorrect one becomes worthless.
What makes Polymarket distinctive
-
Probability-based pricing instead of fixed betting odds
-
Broad topic coverage, including politics, economics, crypto, and global news
-
High speed and liquidity, enabled by crypto infrastructure
-
Use as an information signal, increasingly referenced by media and analysts as a crowd-based expectation indicator
How it differs from traditional betting
Rather than placing a fixed bet, users trade positions at market prices and can exit before resolution. This gives Polymarket a structure closer to a financial market than a conventional betting site.
This model makes Polymarket directly comparable to both regulated event contract exchanges and crypto-native prediction market projects.
How Are Polymarket-Like Companies Classified?
Although they appear similar on the surface, companies comparable to Polymarket differ significantly in terms of legal structure, technology, and user experience. Regulation level and infrastructure choice largely determine who a platform is suitable for.
Broadly speaking, Polymarket-like platforms fall into three main categories:
-
Regulated Event Contract Platforms
Government-supervised exchanges, mostly US-based, operating under derivatives or commodities regulation. -
Crypto and DeFi-Based Prediction Market Projects
Permissionless platforms running on blockchains, relying on smart contracts and oracle systems. -
Betting Exchanges and Forecasting Platforms
Platforms focused on peer-to-peer betting or probability forecasting without true event contract trading.
Regulated Event Contract Platforms
The closest functional equivalents to Polymarket are regulated event contract platforms. These companies frame prediction markets as derivatives products and aim to operate within established legal frameworks, particularly in the United States. Unlike crypto platforms, product scope and access are strictly shaped by regulation.
Key companies in this category include:
-
Kalshi
A CFTC-regulated exchange offering contracts on macroeconomic and political events. -
PredictIt
An academically oriented platform focused on political markets, operating under investment limits. -
ForecastEx
A regulated forecast exchange emphasizing financial-style market structures. -
CME Group / FanDuel Predicts
A major traditional derivatives operator entering the event contract space via FanDuel. -
Crypto.com Derivatives North America (CDNA)
A crypto-native brand leveraging a regulated US derivatives framework to offer event contracts.
Crypto and DeFi-Based Prediction Market Projects
Unlike regulated platforms, these projects operate permissionlessly on blockchains. Market creation, pricing, and settlement are handled through smart contracts and oracles, allowing global access but introducing liquidity and dispute-resolution risks.
Notable projects include:
-
Augur
One of the earliest decentralized prediction markets on Ethereum, known for its oracle and dispute mechanisms. -
Omen
A Gnosis-based platform using AMM liquidity pools to simplify market creation. -
Polkamarkets
A multi-chain Web3 protocol integrating various oracle and arbitration solutions. -
Zeitgeist
A Polkadot/Kusama project exploring experimental concepts such as futarchy. -
Seer
A platform supporting binary, categorical, and scalar markets with oracle-based resolution.
Betting Exchanges and Forecasting Platforms
These platforms do not use true event contracts, but they still allow users to express views on future outcomes. As a result, they are often mentioned alongside Polymarket-like companies, even though their models differ.
Key examples include:
-
Betfair
The world’s largest betting exchange, enabling peer-to-peer betting through back and lay positions. -
Smarkets
A platform blending betting exchange mechanics with prediction market language. -
Metaculus
A non-monetary forecasting platform focused on expert and community probability estimates. -
Manifold
A play-money prediction market emphasizing reputation and forecasting accuracy. -
Hypermind
A professional forecasting platform designed primarily for institutional use.
The Future of Prediction Markets
The rise of Polymarket and similar platforms shows that prediction markets are no longer a niche experiment. In the coming years, they are likely to become increasingly intertwined with financial data, media, and public opinion analysis. Their ability to express expectations as probabilities gives them an advantage over polls and traditional betting models.
One of the most significant trends ahead is the convergence of regulation and crypto infrastructure. Regulated event contract platforms are expanding their offerings, while crypto-based projects are moving toward greater transparency and accountability. In this evolving landscape, Polymarket is well positioned to remain a reference point due to its flexibility and broad market coverage.
Another key development is the repositioning of prediction markets as data-generating systems, not just wagering products. Media organizations, analysts, and advisory firms increasingly treat market prices as meaningful signals of collective expectations.
Ultimately, prediction markets are set to evolve into a distinct digital layer where future outcomes are continuously priced. Polymarket and similar companies are likely to sit at the center of this transformation, shaping how uncertainty is measured and traded in the years ahead.
