Polymarket Overview: A Beginner's Guide to Prediction Markets

Prediction markets let people trade shares based on what they think will happen in the world. Polymarket is one of the biggest platforms for this, where users can bet on events ranging from sports results to political decisions.

Each outcome has a price between 0 and 1, showing how likely the market thinks it will happen. Traders can buy shares if they think the price is too low or sell if they see it rising. You can close a trade at any time, which makes the platform flexible and active. Trades use USDC, a digital dollar, and run on the Polygon blockchain.

While many people treat it like betting, Polymarket works more like a market where users interact directly. The platform also focuses on building a strong user base and liquidity, setting the stage for ways to make money beyond everyday trades.

How Does Polymarket Work?

Polymarket is an online platform where people trade on the outcomes of future events. It works as a prediction market, which means users buy and sell shares based on what they think will happen. These events can cover many topics, such as sports results, political decisions, or entertainment awards.

The basic idea is simple. Each event has different possible outcomes, usually labeled “Yes” or “No.” Users purchase shares that represent their prediction. The price of a share shows how likely the market believes that outcome is. For example, if a “Yes” share trades at $0.20, the market currently estimates a 20 percent chance that the event will happen.

Every share costs between $0.00 and $1.00 and uses USDC, a digital dollar-backed currency. Each pair of outcomes, such as “Yes” and “No,” is backed by $1. When traders agree on prices from both sides, the system creates shares so that the total value equals $1. After the event ends and the final result is confirmed, shares that match the correct outcome pay out $1 each. The other shares lose their value.

If someone believes the market price underestimates the real probability, they can buy shares. For instance, a trader might see a team’s chances as higher than the current price suggests and buy “Yes” shares. If the team wins, those shares settle at $1 each, creating a profit.

Polymarket works like a marketplace rather than a traditional betting site. Users trade directly with other users. Because of this setup, you’re free to sell your shares before the event finishes. Many traders do this to lock in profits or reduce losses when prices change.

Prices move constantly as people react to news, polls, and new information. This trading activity pulls together many viewpoints into one number. Supporters of prediction markets believe this process often produces more accurate estimates than polls or expert opinions, since participants have real money on the line when making their predictions.

Who Owns Polymarket?

Polymarket is a private company, so its shares do not trade on a public stock market. A small group of people and investment firms hold the ownership. The largest stake belongs to the founder, Shayne Coplan, along with several venture capital firms and strategic investors that joined later funding rounds.

Coplan started Polymarket in 2020 as a platform where people could trade predictions about real-world events. He built the company from scratch and kept a meaningful ownership stake as outside money came in. Reports suggest he owns roughly 11 percent of the company. That share helped push his personal wealth past the billion-dollar mark once the company’s valuation climbed. Even though his stake shrank as investors joined, founders often keep special voting rights that allow them to maintain control of major decisions.

The biggest outside investor today is Intercontinental Exchange, the company that owns the New York Stock Exchange. In 2025, ICE invested about $2 billion in Polymarket for a stake that could reach about 25 percent. The deal raised the company’s value to roughly $9 billion and tied the startup to one of the most powerful financial networks in the world.

Earlier funding came from well-known venture capital groups. Founders Fund, created by Peter Thiel, led a $45 million investment round in 2024. Crypto-focused firm Blockchain Capital and venture investor General Catalyst also backed the company during later funding rounds. Support from individuals in the tech and crypto space added more capital and credibility.

Because Polymarket remains private, the company does not publish a detailed ownership chart. Still, the broad picture is clear. Coplan remains the key shareholder and public face of the company. Large financial and venture investors hold smaller pieces after funding rounds.

Is It Like Gambling?

People often ask whether using Polymarket counts as gambling. The answer depends on how someone views it, yet many analysts say it works in a similar way to betting.

Trading works through a system similar to stock exchanges called a central limit order book. This means users place orders at prices they choose, then wait for another trader to accept them.

A person can also accept an order that already sits in the order book. The order book shows the prices buyers offer and the prices sellers want. When news appears, such as a sports injury or a new poll, traders react, and prices shift. Someone who bought a share does not need to wait for the final result.

If the price rises, they can sell early and lock in a gain. If the market moves the other way, they may sell to cut their losses.

Because every trade involves two people taking opposite positions, one trader’s gain comes from another trader’s loss. Economists describe this structure as zero-sum. Over time, platform fees also reduce the average return for users.

Polymarket takes a 2% fee on profits and charges a small trading fee for each contract. These costs add up if someone trades often.

The platform runs on the Polygon network and uses USD Coin for payments. Transactions appear on the blockchain, which creates a public record that anyone can check. Supporters say this system improves transparency. At the same time, users must protect their own crypto wallets. Lost keys or hacked wallets usually mean lost funds. Even though fees on Polygon remain small, frequent trading can still create noticeable costs.

Markets on the platform also vary by time. Some resolve within minutes, while others last months or even a year. Very short markets can feel exciting because results arrive quickly, yet prices may jump around fast, which makes calm decisions harder.

When a market ends, the platform must determine the correct outcome. Polymarket relies on the optimistic oracle system from UMA Protocol. After an event finishes, someone submits a proposed result along with a financial bond.

Other users get a short window to challenge that answer. If nobody disputes it, the market settles and winning shares pay $1 each. When a dispute happens, token holders in UMA vote on the correct result through a verification process that can take several days.

Researchers from Columbia University have also reported signs of wash trading on the platform. Wash trading involves repeatedly buying and selling to create the appearance of high activity. If trading volume appears larger than it truly is, some users may believe a market has stronger participation than it actually does.

For these reasons, many critics still treat Polymarket as a form of gambling rather than a traditional investment. The system may provide information about public expectations, yet it does not represent ownership in a business or a productive asset.

Losses vs Gains

Trading on Polymarket can lead to big gains for some, but most users end up losing money. About 70% of traders lose funds over time because Polymarket is a high-risk, negative-sum market. That means after fees and trades by professional arbitrageurs or bots, most users’ money is slowly drained. Some losses reach millions if traders make poor decisions or bet too much on a single outcome.

Gains happen when a user correctly predicts an event or buys shares at a low price and sells them later at a higher price before the market closes. Each share represents a probability and costs between $0.00 and $1.00. A share priced at $0.40 shows the market thinks there is a 40% chance the event will occur. If the event happens, the share settles at $1.00, creating a $0.60 profit per share minus any fees. If the event does not happen, the share becomes worthless, and the money invested in it is lost.

Traders don’t have to wait until an event ends to take profits. Since shares can be sold at any time, a price rise allows users to lock in gains before the outcome is final. Strategies for earning include spotting mispriced shares faster than others, providing liquidity by offering competitive buy and sell prices, or exploiting small differences in share prices across markets. Some markets even offer small rewards for holding positions over time.

However, risks remain high. Buying at high prices leaves little room for profit. Low liquidity in smaller markets can make selling shares difficult. Users also face competition from professional bots and informed traders who can move markets against casual participants. Gains are taxable, and traders must keep track themselves. Polymarket can offer profits, but most users lose money if they overcommit, ignore risk management, or bet impulsively.

What Are the Risks of Using Polymarket?

Using Polymarket may look simple, yet several risks come with it. Anyone thinking about using the platform should understand how those risks work before putting money in.

The first risk involves financial loss. Polymarket works as a zero-sum market. One trader’s gain comes from another trader’s loss. Over time, spreads, slippage, and platform fees slowly eat into returns. Many people lose money even if they win a few trades along the way. Some platforms highlight stories about big winners, yet those cases rarely show what the average user experiences.

Addiction also worries many observers. The platform runs all day and night. Prices change constantly as news appears or rumors spread. Frequent updates, notifications, and fast-moving markets can pull users into checking prices again and again. Some people start chasing losses after a bad trade.

Consumer protections also remain limited compared with traditional betting sites. Many licensed sportsbooks set deposit limits, offer cooling-off periods, or provide self-exclusion tools. Prediction markets often lack those safeguards. That situation can expose users to more financial pressure if they trade impulsively.

Crypto and data risks also matter. Polymarket uses USD Coin and operates on the Polygon system. Users usually connect their own wallets. A stolen password, a hacked device, or a lost seed phrase can lead to permanent loss of funds. Blockchain transactions cannot easily be reversed.

Market conditions can create additional problems. Some markets attract only a small number of traders. Low liquidity makes it harder to buy or sell shares at fair prices. Large trades can push prices around in these thin markets. A well-informed trader may also move prices before others understand what happened.

The platform also depends on data verification from the Oracle system run by UMA Protocol. If a dispute occurs or a question gets worded poorly, settlement may take longer than expected.

Regulation adds another layer of uncertainty. Laws around prediction markets continue to shift in many countries. Anyone considering participation should check local rules and only risk money they can afford to lose.

What Countries Ban Polymarket

Polymarket restricts trading in many countries to follow legal rules and international sanctions. People in the United States, France, Germany, Italy, and the United Kingdom cannot place new trades. Australia, Belgium, Belarus, Burundi, Central African Republic, Congo (Kinshasa), Cuba, Ethiopia, Iran, Iraq, North Korea, Lebanon, Libya, Myanmar, Nicaragua, Russia, Somalia, South Sudan, Sudan, Syria, the United States Minor Outlying Islands, Venezuela, Yemen, and Zimbabwe are also fully blocked.

Some countries allow limited access, meaning users can close existing positions but cannot open new ones. These include Poland, Singapore, Thailand, and Taiwan.

Even inside countries that normally allow Polymarket, certain regions are blocked. Ontario in Canada and Crimea, Donetsk, and Luhansk in Ukraine are restricted.

These restrictions exist because governments treat prediction markets like gambling or financial services. Polymarket lets people bet on future events, which some regulators see as political or financial risk. Other U.S. platforms, such as Kalshi, face similar limitations in certain states because of these rules.

The bans are sometimes temporary. Hungary, for example, has a temporary block, and authorities could lift it later. Regulators keep a close watch in countries where trading is allowed to ensure compliance with anti-money laundering, financial, and gambling rules.

Why Was Polymarket Fined Millions in 2022?

In January 2022, Polymarket was fined $1.4 million by the Commodity Futures Trading Commission (CFTC) https://www.cftc.gov/ because it allowed users to trade binary options on real-world events without being registered as a designated contract market or swap execution facility, as required under U.S. law.

These contracts counted as “swaps,” meaning they fell under the CFTC’s rules for trading and oversight. The agency said Polymarket offered “substantial cooperation” during the investigation, which led to the fine being smaller than it might have been otherwise. The CFTC also issued a cease and desist order, forcing Polymarket to stop offering unregistered markets to U.S. customers. Essentially, the company had been running a U.S.-based trading platform without proper licensing.

After the enforcement action, Polymarket temporarily shut down its services for American users and worked on a way to return legally. The company eventually acquired a U.S.-regulated derivatives exchange, which allowed it to operate under the CFTC’s supervision. This move let Polymarket bring U.S. customers back and comply with all federal rules for trading event-based contracts. By mid-2026, the platform received an amended order of designation from the CFTC, officially approving its operations in the United States.

Polymarket still faces restrictions in some countries where online prediction markets or event-based betting are considered illegal. While the platform is active in the U.S., it remains unavailable in jurisdictions that ban these kinds of markets, though the exact list of countries varies based on local gambling and financial regulations. In this context, other U.S.-based platforms like Kalshi have faced similar challenges from state gaming regulators but operate under separate legal frameworks.

What Is the 7% Loss Rule with Trading?

The 7% loss rule is a simple way to protect yourself when trading. It says that if the price of something you bought falls by about 7% from what you paid, you should sell it right away. This helps stop a small loss from turning into a bigger one.

For example, if you buy a share for $0.50 and it drops to $0.465, the rule says to sell. This keeps your money safe so you can use it for other trades that have a better chance of winning.

On platforms like Polymarket, this rule is useful because prices can change fast. Shares can swing up or down a lot depending on news or opinions. Following the 7% rule helps you avoid holding onto a losing position in the hope it will bounce back.

The main idea is to take the emotion out of trading. Instead of worrying or hoping, you just follow a set plan. The 7% level is big enough to avoid normal ups and downs, but not so big that you risk a major loss.

Traders can adjust it slightly if a market is very jumpy. Some might use 10% instead or look at average price changes to set a safer limit. The goal is always the same: protect your money, keep trading without stress, and be ready to move to better opportunities.

This rule also helps when prices are high. If a share costs $0.65 or more, losing 7% can be a bigger bite out of your capital. Knowing where to set your limit keeps your losses under control and makes your trades less risky.

Does Polymarket Charge Fees?

Polymarket usually doesn’t charge fees on most of its markets. For everyday trading, you can buy and sell shares without giving the platform a cut. You’ll only pay for network gas fees when moving money on the blockchain and any fees your payment provider might charge if you use services like Coinbase or MoonPay. The main cost you see while trading is the small difference between the buy and sell prices, called the bid–ask spread, which goes to liquidity providers who keep the markets active.

Some markets, like crypto and certain sports events, do have a small taker fee. These fees depend on the market’s activity and the probability of the outcome. For example, in crypto markets, the fee can reach up to about 1.56% when a market is most uncertain and drops as the odds lean toward one side. Polymarket sends a portion of these fees back to market makers to encourage them to provide liquidity, so trades remain smooth and easy for everyone.

Polymarket makes most of its money in ways that don’t directly charge everyday traders. The platform sells real-time market data to institutions and media outlets that want to see where crowds are putting their bets. It also earns interest from holding large amounts of USDC and may generate some income through the POLY token ecosystem and small pilot fees in specific markets. Essentially, Polymarket focuses on growing its user base and trading activity first, and earns revenue from data and other services behind the scenes.

What Costs do Users Pay?

When you trade on Polymarket, there are a few costs you might notice. One of them comes from the difference between the price you pay to buy and the price you get when you sell. This difference is called the bid–ask spread. Trades on Polymarket happen through automated market makers, which set prices based on supply and demand. The small gap you pay doesn’t go to Polymarket—it goes to the people who provide liquidity so the market can run smoothly.

Every trade also uses the Polygon blockchain, which means network fees, often called gas fees, apply. These fees cover the cost of processing your transaction on the blockchain. They’re usually much lower than fees on Ethereum, but they can still add up when you make deposits, withdrawals, or settle trades on the platform.

If you buy USDC through a service like MoonPay or Coinbase, that service may charge an extra fee. These fees are separate from anything Polymarket charges. They cover the cost of converting your dollars into cryptocurrency or sending crypto back into your bank account.

Overall, you don’t pay a traditional trading fee directly to Polymarket. The main costs come from the bid–ask spread, blockchain gas, and any fees from the payment service you use to bring money in or take it out.

Polymarket Alternatives

If you’re thinking about trying prediction markets but want something different from Polymarket, there are several alternatives to consider. Each platform has its own rules, markets, and ways to deposit funds, so choosing the right one depends on what matters most to you.

Crypto.com Predictions

Crypto.com Predictions works well for U.S. users. It’s fully regulated, so you can trade legally without worrying about geo-blocking. You can use USD already in your Crypto.com account, and the app handles payments and fees directly, making it simple for beginners and experienced traders alike.

Gemini Predictions

Gemini Predictions runs on the Gemini exchange and offers a trading experience similar to Polymarket. You can trade politics, sports, crypto, and economic events. Contracts cost between $0 and $1, and if the event happens, you earn $1. Fees are low, and U.S. residents can trade safely.

Kalshi

Kalshi lets you trade using dollars or crypto and is fully CFTC-regulated. You complete standard KYC checks before trading. The platform covers politics, sports, crypto, earnings, and culture. While fees apply, Kalshi is beginner-friendly and works with standard payment methods like debit cards and Apple Pay.

Myriad

Myriad is a decentralized prediction market on BNB Chain, Linea, and Abstract. It uses smart contracts to settle bets automatically and supports politics, sports, and culture. Beginners can try virtual points to learn how markets work. Trading volumes are low, so spreads can be wide for big bets.

OPINION

OPINION focuses on serious macroeconomic events like interest rate decisions. The platform offers clear market rules and order book data. It’s decentralized on BNB Chain and charges takers 0–2% per trade. Users earn points by providing liquidity and holding tokens, which may allow future rewards.

When you’re choosing the right Polymarket alternative, start by checking if you can trade in your country. U.S. users need platforms regulated by the CFTC, like Kalshi or Gemini Predictions. Non-U.S. users have more options, including Myriad and OPINION.

Think about payment preferences. Some platforms let you use USD and cards, while others require crypto like USDT. If you want simple deposits, stick to fiat-friendly options like Kalshi.

Decide how serious you are about trading. Casual users might enjoy Predict.fun or Myriad for entertainment markets and easy-to-understand interfaces. If you focus on financial or macroeconomic markets, OPINION gives more detailed tools and higher liquidity.

Finally, consider the type of markets you like. Political events, sports, crypto, or culture each have platforms that focus on those areas. Pick one that fits your interests and trading style.

Polymarket Plays the Long Game

Polymarket doesn’t profit directly from your trades. The platform lets users trade shares on future events, like politics, sports, or entertainment, using USDC on the Polygon blockchain. Share prices reflect the market’s collective probability, and traders can buy or sell anytime, making it feel like a dynamic prediction market rather than traditional betting.

Rather than earning from every transaction, Polymarket is focused on the long game. The company builds liquidity, engages users, and provides real-time market data for institutions. Revenue comes from selling insights, earning interest on USDC, and experimenting with the POLY token ecosystem. Venture capital backing from firms like Founders Fund and Intercontinental Exchange lets Polymarket prioritize growth and accuracy over short-term profits. By fostering a loyal user base and a transparent, liquid market, Polymarket positions itself to monetize effectively in the future while shaping the prediction market industry.
