Markets that let people speculate on future outcomes have existed for centuries, with documented activity in Renaissance Italy. The core idea is unchanged, but modern technology reshapes access, trade flow, and—at times—the accuracy of aggregated predictions.
Launched in 2020, Polymarket is a leading decentralized prediction platform where users stake crypto instead of cash on upcoming events. This guide explains how the system functions, how the project may be funded, and why its design differs from legacy prediction venues.
What Is Polymarket?
Polymarket is a crypto‑native prediction marketplace founded in 2020 by Shayne Coplan. In essence, it is a blockchain application for betting on real‑world outcomes using digital assets.
Markets span everything from major sports fixtures to presidential races, scientific milestones, and pop‑culture moments, enabling users to capitalize on research, expertise, or intuition. Common categories include politics and public policy, macro and business indicators, crypto and tech milestones, entertainment, and major sporting events. In practice, markets work best when they are framed as objectively verifiable questions; prompts that are ambiguous, unlawful, or difficult to resolve may be restricted or closed.
The platform runs on the Polygon network and relies on smart contracts for automated custody and settlement, removing traditional intermediaries. Trading, liquidity, and payouts are denominated in USD Coin, a dollar‑pegged stablecoin, which streamlines global access and reduces price volatility relative to crypto assets.
Polymarket drew notable attention for transparent forecasting during recent election cycles. It has also navigated regulatory challenges, including questions from the Commodity Futures Trading Commission about registration and user geography—making it a bellwether for blockchain‑based prediction markets.
How Does Polymarket Work?
Polymarket is a Web3 application for forecasting real‑world events without mandatory know-your-customer checks, favoring pseudonymous participation. The design aims to surface honest signals while limiting identity bias. Key mechanics include the following.
1. Market Creation
Any user can draft a market, such as “Will [event] occur by [date]?” Creators specify outcomes (commonly Yes/No) and set clear resolution criteria so traders understand how results will be determined. Others then place positions based on their view, research, or the latest news.
2. Pricing and Odds
As orders hit the book, prices adjust in real time, shifting the implied probability—much like a price move on an exchange. Heavier interest in one side pushes odds toward that outcome, reflecting the crowd’s consensus. Example markets include questions like whether the Bitcoin price will hit a threshold within a window.
3. Liquidity Providers
Liquidity providers supply depth so traders can enter and exit efficiently. Their funds help stabilize spreads and enable continuous trading, even when sentiment or trend momentum changes quickly.
4. Smart Contract Governance
Self‑executing smart contracts manage trades and escrow, lowering operational risk and manual overhead. This automation enhances security and helps ensure consistent settlement across markets.
5. Outcome Verification
When events conclude, oracles retrieve off‑chain facts, and a Market Integrity Committee oversees disputes and edge cases. This process is designed to resolve markets fairly and transparently before payouts.
How Do I Get Started With Polymarket?
To start, set up a compatible self‑custody wallet, then add funds to it from an exchange or another wallet. Next, open the Polymarket app in your browser and connect your wallet when prompted. Deposit funds into the platform, choose a market, select the outcome you want, enter a position size, and confirm the transaction in your wallet. Polymarket is a platform rather than a coin you can buy, so participation typically means trading outcome shares using a stablecoin balance and withdrawing back to your wallet when you are done.
What Cryptocurrency Do I Need for Polymarket?
Users can transfer assets such as Ether, Wrapped Ether, Solana, Polygon’s native token, USD Coin, Tether, and Dai from networks including Polygon, Ethereum, Base, Arbitrum, and Solana. Deposits are automatically converted to USD Coin for trading and settlement. Keep a small amount of the native coin on each chain to cover gas fees.
Because balances are converted on arrival, withdrawals are also made in USD Coin.
| Supported Asset | Supported Network | Purpose (Deposit/Withdrawal/Gas) |
|---|---|---|
| Ether | Ethereum | Deposit (converted to USD Coin). Gas on Ethereum. |
| Wrapped Ether | Ethereum, Polygon | Deposit (converted to USD Coin). |
| Solana | Solana | Deposit (converted to USD Coin). Gas on Solana. |
| Polygon’s native token | Polygon | Deposit (converted to USD Coin). Gas on Polygon. |
| USD Coin | Polygon, Ethereum, Base, Arbitrum, Solana | Deposit and withdrawal. Trading and settlement currency. |
| Tether | Polygon, Ethereum, Base, Arbitrum, Solana | Deposit (converted to USD Coin). |
| Dai | Polygon, Ethereum | Deposit (converted to USD Coin). |
How Does Polymarket Make Money?
Polymarket does not charge fees for creating markets or trading. The project appears to be pursuing a longer‑term strategy not yet fully disclosed.
To date, operations seem supported by venture funding totaling about $74 million from investors including Polychain Capital, DragonFly Capital, and Founders Fund, alongside angels such as Ethereum co‑founder Vitalik Buterin. Users also speculate that data products could provide revenue.
Polymarket does not currently have a native token or coin. The team has not published an official roadmap for a token launch, and any “Polymarket coin” claims are best treated as speculation unless confirmed by the project.
Polymarket is privately operated and does not publish detailed financial statements, so outside observers cannot verify whether it is profitable or operating at a loss. Given the lack of trading fees, long‑term sustainability likely depends on funding, operating costs, and whether new revenue lines—such as data products—materialize.
Data Monetization
Aggregated, anonymized trading activity can reveal sentiment, trend shifts, and forecasting performance. Institutions such as analysts, enterprises, and political organizations value these insights. Selling data in privacy‑preserving form offers a potential revenue stream without exposing individual users.
How Can I Make Money on Polymarket?
Two primary approaches exist: active speculation and providing liquidity.
Speculating
Traders buy outcome shares priced from $0.00 to $1.00, which mirror implied probability. If you purchase at $0.45 and the event resolves in your favor, the share settles at $1.00, realizing profit in USD Coin. While risky, disciplined research can improve edge over time.
Because Polymarket does not have a native token with a single market price, what you see as “prices” on the platform are the market prices of outcome shares, typically quoted as a fraction of a dollar in USD Coin.
Providing Liquidity
Users seeking passive yield can supply liquidity instead of directional bets. Here is the general flow:
- Place limit orders that contribute depth to a market’s pool, supporting tighter spreads and smoother trade execution.
- Rewards are shared among liquidity providers and vary by market activity and competitiveness.
Returns depend on order placement, market balance, and event probabilities. Adverse moves can cause significant losses. All gains and exposure remain in USD Coin.
Advantages of Polymarket
Several benefits arise from its blockchain design and open architecture.
- Transparency: Transactions and settlements are recorded on‑chain, creating a tamper‑resistant audit trail.
- No Transaction Fees: The platform does not charge for deposits, withdrawals, or trading activity.
- Anonymity: Users can participate without know-your-customer checks, preserving privacy while they trade.
- Efficiency: Smart contracts automate custody and settlement, reducing delays and operational cost.
- Community‑Driven: User‑created markets foster engagement and collaborative discovery.
Polymarket’s Risks and Key Considerations
As with any prediction venue, users should weigh potential downsides before committing funds.
- Regulatory Uncertainty: Evolving rules can lead to legal exposure or market restrictions.
- Market Manipulation: Bad actors may attempt to sway odds, prices, or sentiment.
- Volatility: Outcomes can shift rapidly, causing losses for traders and liquidity providers.
Is Polymarket Legit?
Polymarket’s model is innovative yet controversial, having earned praise for transparency while encountering regulatory and integrity questions. Two notable episodes illustrate the tension.
Wash Trading Allegations
During the 2024 U.S. presidential race, one market implied roughly a 67% chance of a Trump victory, while researchers accused the platform of wash trading to inflate activity. Polymarket denied the claims, underscoring the need for rigorous oversight and clear disclosures.
Commodity Futures Trading Commission Issues
In 2021, the U.S. Commodity Futures Trading Commission investigated unregistered markets. By January 2022, Polymarket paid a $1.4 million fine and wound down certain products to comply, highlighting the shifting regulatory environment for crypto prediction tools.
Is Polymarket Accurate?
The platform does not predict the future; it aggregates crowd opinions based on available information, so accuracy mirrors the quality of its participants’ research and the timeliness of news.
In well-designed markets with clear resolution rules and meaningful liquidity, the final price often compresses a wide range of information into a single probability—useful as a signal, but never a guarantee.
In high‑attention markets, prices often move quickly as news breaks, sometimes updating faster than traditional polling averages or commentary. At the same time, prediction prices can be less reliable in thin markets, during sudden sentiment swings, or when participants attempt to influence odds, making them best used alongside other benchmarks rather than as a standalone forecast.
Polymarket gained visibility in the 2024 election season for closely tracking sentiment. Still, markets measure beliefs about what will happen—not guarantees—so outcomes can diverge from expectations.
Polymarket Competitors
Other prediction venues also blend markets and crypto, each with different governance and compliance models.
PredictIt
A regulated, centralized platform focused on political forecasting. PredictIt rose to prominence around the 2016 U.S. elections. It emphasizes compliance and simplicity but differs from Polymarket’s decentralized structure.
Kalshi
A regulated exchange built for event contracts across categories, offering a centralized alternative for users who prioritize strict legal frameworks and reliability.
Hedgehog Markets
A decentralized prediction platform on Solana featuring low fees, transparent settlement, and community governance, delivering fast trade execution.
Closing Thoughts
Polymarket fuses blockchain infrastructure with prediction markets, enabling participants to trade event outcomes with real‑time odds as price signals on everything from sports to financial events.
As with any speculative tool, approach with care: understand mechanics, assess risks, and size positions responsibly.
FAQ
How Does Polymarket Verify Event Outcomes?
The platform relies on oracles to pull real‑world data and a Market Integrity Committee to adjudicate edge cases, promoting accurate and unbiased resolution before payouts.
Is Polymarket Legal and Safe to Use?
Security derives from smart contracts and on‑chain settlement, but legality varies by jurisdiction. In 2022, Polymarket paid a Commodity Futures Trading Commission fine in the U.S. Always check local rules before you trade.
How Do I Become a Liquidity Provider on Polymarket?
To provide liquidity, allocate funds to a target market and place limit orders near the prevailing price. Rewards depend on how competitively your orders are positioned and overall demand. Note that sudden price shifts can produce losses; for example, supplying $1,000 when an outcome trades at $0.60 versus $0.40 can lead to a meaningful drawdown if odds move against your inventory.
