What Is Polymarket, and How Does It Work?
Polymarket is a crypto prediction market that lets you trade on what you think will happen in the real world, whether in sports and culture, or in science and crypto. It was built on Ethereum by Shayne Coplan and transferred to Polygon to reduce fees.
Politics put it on the map. The 2024 U.S. election attracted bets of over $1 billion. As of February 2026, sports and crypto milestone markets are capturing the majority of attention, with Super Bowl markets leading the way.

Key Takeaways
- Polymarket is an on-chain predictions market, built on Ethereum and eventually moved to Polygon.
- It works by creating “markets” for specific events and allowing users to buy “Yes” or “No” shares based on the event outcome they’re expecting.
- You can use it by signing up, choosing a market, buying shares, and withdrawing any funds for successful predictions.
What Is Polymarket?
Polymarket is one of the top crypto prediction markets. It allows people to trade outcomes of real-world events, such as elections, economic indicators, sports results, or geopolitical developments.
In other words, instead of asking people what they think will happen, Polymarket lets participants put money behind their beliefs, effectively turning opinions into market prices. Each market is framed as a clear, binary question, such as whether a specific event will occur by a certain date. The prices of the outcomes reflect how likely traders believe the event is.
Because participants risk capital, Polymarket is often described as an information aggregation tool; it combines diverse views, incentives, and real-time updates into a single probability-like signal.
With this in mind and as a crypto-native platform, Polymarket sits at the intersection of financial markets, data forecasting, and blockchain technology:
- Unlike traditional betting sites, it’s built with crypto infrastructure, which emphasizes transparency, fair and free pricing, and non-custodial ownership.
- Unlike opinion polls, it updates continuously as new information becomes available while encouraging honest forecasting by tying it to financial risk and reward.
For these reasons, the platform is used not only by traders but by researchers, journalists, and analysts. Particularly in areas like politics, macroeconomics, and geopolitics, as a live indicator of expectations.
How Does Polymarket Work?
Polymarket works by creating markets for future events and allowing users to buy shares, which are typically tied to mutually exclusive outcomes, typically “Yes” or “No.” Each share settles at $1 if the outcome happens and $0 if it does not.
If a “Yes” share is trading at $0.65, the market is effectively saying there is a 65% implied probability of that event occurring. These prices move continuously as traders react to news, data, and each other’s views.
Taking this example, if you bought a “Yes” share at $0.65 and the event does happen, you get $1, meaning you profited $0.35. The platform is funded with stablecoins (cryptocurrencies designed to maintain the same price as the U.S. dollar).
Technically speaking, trading is handled via a central limit order book (CLOB), the same mechanism used by stock exchanges. Users place trades at chosen prices, and trades execute when prices match. This allows for precise pricing, liquidity, and continuous price discovery.
While order matching happens off-chain for speed, settlement occurs on-chain to ensure transparency, security, and user custody.
When an event concludes, the market must be resolved. To do this, Polymarket uses an optimistic oracle system, where an outcome is proposed and assumed correct unless challenged.
If someone disputes the result, they must submit a financial bond. This creates an incentive to challenge only genuine errors and encourages accurate outcomes without relying on a central authority.
Example: Polymarket Event Contract in Practice
Let’s illustrate this with a make-believe scenario. Who would come first in a 100m race: Usain Bolt or Noah Lyles? Once a market has been established, the odds presented to users change in real time, and bettors can purchase shares based on what they think will happen.
These shares are priced in cents and are a reflection of how likely an outcome is. For example, if shares in Usain Bolt cost 80 cents, that means the market thinks there’s an 80% chance that he would win. Betting on Noah Lyles would cost 20 cents.
As the race approaches, these odds may evolve, meaning shares in Lyles could rise in value (say, from 20 cents to 35). Those who backed him early on can sell their shares whenever they like, enabling them to generate a profit even before the outcome is known. In this case, if they bought at $0.20 and sold at $0.35, they made a $0.15 profit per share.
When the final result comes through, if Lyles emerges victorious, his shares would automatically be worth $1, while Bolt’s would be worth $0:
- Those who bought Bolt shares at $0.80 lose their whole stake.
Those who bought Lyles shares at $0.20 profit $0.80 per share; if they bought at $0.35, they profit $0.65, and so on.
Is Polymarket Legit?
Polymarket is a legit platform. It has been running since 2020, with transparent information about the team and founder, Shayne Coplan, a New York-born entrepreneur. Even big financial firms like Bloomberg LP use election odds data from Polymarket.
While Polymarket is legitimate, it’s still not recommended to bet more than you can afford to lose. Additionally, there are concerns that wealthier bettors could potentially influence market outcomes, making it even riskier.
How Accurate Is Polymarket?
That’s a really interesting question. Given how Polymarket users are putting their money where their mouth is, this platform can be an up-to-the-minute insight into sentiment. Founder Shayne Coplan has even argued the website had anticipated Joe Biden would crash out of the U.S. race before the media did — and that Donald Trump would select JD Vance as his running mate.
One of Polymarket’s distinct advantages lies in how it can provide an instantaneous barometer of public opinion, while polls from data companies may only emerge days after a breaking news event has taken place. That helps explain why Bloomberg began to integrate the platform’s data into its Terminal service — adding a much-needed sheen of credibility.
Another significant development came when the company hired Nate Silver as an adviser — a renowned statistician who made his name by making in-depth predictions about past presidential elections.
How to Use Polymarket in the U.S.
Despite American politics emerging as one of the biggest use cases for Polymarket, it was initially unavailable in the US. All of this follows a case that was brought by the Commodity Futures Trading Commission, which found the company was an unregistered binary options trading platform.
As part of a settlement reached in 2022, Polymarket was ordered to pay a $1.4 million penalty and told to stop offering operations within the country altogether. However, after acquiring a licensed exchange and receiving approval from the CFTC, Polymarket is now available in the U.S.
Right now, to use Polymarket legally in the United States, you must use the CFTC-regulated platform, not the global one, and it usually involves:
- Identity verification (KYC): You must verify your identity and confirm you are at least 18 and legally eligible to trade in your state.
- Account-based access: Unlike the global platform’s wallet-only model, the U.S. version typically uses accounts tied to regulated clearing and custody arrangements.
- Fully collateralized trading: You must deposit the full amount needed to support any position, no leverage or borrowing.
- Market availability limits: Some market categories, such as certain sports or sensitive event contracts, may be restricted or unavailable depending on state-level enforcement or ongoing litigation.
You should not use VPNs or other methods to bypass geographic restrictions, as this can violate platform terms and potentially increase legal risk.
Step-by-Step Guide: How to Bet on Polymarket
Below is a simple walkthrough for betting on Polymarket. To see a more detailed tutorial, take a look at our guide on how to use Polymarket.
Step 1: Sign Up
On Polymarket’s global platform, you can sign up by connecting a crypto wallet like Best Wallet, MetaMask, or Phantom, or simply use an email or Google account. No KYC (Know Your Customer) verification is required.
- Deposit USDC on Polymarket by transferring it from your wallet or an exchange using the Polygon Network. There’s also an option to buy USDC with a credit card.
- After sending the funds, activate them by clicking “Cash” and selecting “Activate Funds.”
Step 2: Pick a Market
Choose a Polymarket strategy and market that interests you from the available categories. For example, select the 2024 U.S. Presidential Election winner market.
Step 3: Buy and Sell Shares
To buy, select your prediction, enter the amount of USDC to invest, and place your order. You can sell your shares before the market concludes. If the odds improve, you can sell for a profit. If they drop, you can sell early to limit losses. You can also set limit orders for automated buying or selling when prices reach a certain point.
Step 4: Withdraw Funds
To withdraw, go to “Cash,” click “Withdraw”, enter the wallet address and amount, and confirm. Make sure to use the Polygon Network for the transaction.
How Does Polymarket Make Money?
According to Polymarket’s documentation, it primarily makes money through trading fees, but only on specific products. Most markets trade fee-free. This includes long-term political, economic, and geopolitical questions, as well as deposits and withdrawals.
Fees mainly apply to two categories. The first is 15-minute Polymarket cryptocurrency price prediction markets, which are used to speculate on whether a crypto price will go up or down over the next 15 minutes.
A small taker fee is applied to those trades, but it is not pure platform profit. They’re mostly used to fund the maker rebates program, which pays USDC rewards to liquidity providers who keep markets active.
Specifically in the United States, Polymarket has started charging a very small taker fee, around 0.01%, on some trades, which is a similar revenue model to traditional exchanges.
Future revenue streams that have been discussed include data licensing and institutional access, since the platform’s probability data is seen as valuable.

Is There a Polymarket Coin?
According to Polymarket’s official documentation, the platform does not use a token for trading, governance, or rewards. All markets are collateralized and settled using USDC, a U.S. dollar-pegged stablecoin, and Polymarket explicitly warns users to be cautious of fake “POLY” tokens or airdrop scams.
That said, the idea of a Polymarket coin has been widely discussed. In late 2025, senior Polymarket executives told major crypto outlets that the company plans to launch a token and conduct an airdrop in the future, likely after its U.S. regulatory rollout.
However, no token has been launched, and no details, such as timing, blockchain, token supply, or eligibility, have been publicly confirmed.
Who Has Invested in Polymarket?
Polymarket has attracted support from some pretty big names of late, including Ethereum’s co-founder Vitalik Buterin.
He’s pushed back against criticism that this website amounts to gambling, writing on X:
“Prediction markets are interesting because they’re a social epistemic tool: the public gets a view of how important certain events are and what kinds of things are likely to happen, that is much less vulnerable to biased editorial opinion than either social media or news websites.”
Advantages of Using Polymarket
Some of the most beneficial points in using Polymarket as a prediction platform are:
📆 Wide Range of Event Types
Polymarket offers a variety of betting options on topics like politics, sports, and pop culture. You can bet on everything from the outcome of the U.S. elections to who the next James Bond actor will be, so there’s something for everyone.
🔒 Access to Restricted Betting Markets
Unlike traditional platforms, Polymarket lets you bet on events that are often restricted elsewhere, like political outcomes or finance-related bets. This gives you access to unique markets.
📊 Speculative and Hedging Opportunities
Polymarket allows you to bet on real-world risks, such as elections or crypto prices. This can help you hedge against financial risks by betting on possible outcomes.
Downsides and Risks of Using Polymarket
Polymarket can be fun to use, but it comes with real risks. Most of them come from regulation, market structure, and the fact that you’re trading event outcomes with crypto rails.
🧑⚖️ Regulatory Risk
Rules can change fast. In 2026, some states sent cease and desist notices tied to sports markets, which can block trading overnight. Past U.S. fines show regulators act. Cross-border rules and tax reporting add work.
🌎 Manipulation Concerns
Prices only help when trading is honest. Wash trading claims suggest some volume can be fake, which distorts odds, especially in smaller markets. Anonymity also raises insider trading risk. In sensitive markets, incentives can get ugly.
📈Liquidity and Volatility Issues
Many markets stay thin. When few people trade, a small order can move the price, and you pay slippage. Odds can swing fast after one headline. Polymarket has also faced disputes on self-referential markets, which adds stress.
💻 Operational Downsides
Settlement depends on clear rules and clean data. If an event definition is vague, resolution can drag, and payouts can wait. You also carry wallet risk with crypto deposits. Geofencing and KYC checks can block you mid-trade.
💸 Financial Risks
At the end of the day, you trade outcomes, not a business with cash flow. If you read the event wrong, you lose your stake. Add oracle failures or liquidity pool losses, and the downside stacks up fast.
Will Polymarket Remain Popular?
Polymarket is likely to remain popular, but now it has actual competition. Kalshi is attracting users as it operates within the U.S. rules, and other large platforms are likely to have a share as well. Traffic is now chilled out compared to the 2024 frenzy, and scandals such as wash trading claims are not beneficial.
But Polymarket remains with a good brand awareness and a product that people can get acquainted with quickly. It also possesses financial resources and incentive to drive a U.S. comeback, and space to diversify into sports, where customers are far more numerous than in politics.
Conclusion
Polymarket had a humble launch in 2020, but eventually took the world by storm years later. Since its debut, it has become the premier platform for not only placing bets on-chain but also a leading indicator of public sentiment.
This has led to users of the platform accurately predicting future events, such as the 2024 U.S. presidential election. With talks of Polymarket going public, it likely has a bright future. However, you should keep in mind that gambling involves risks, and you should never bet more than you can comfortably afford to lose.
