What Is Polymarket? How the Prediction Market Works (2026)

Polymarket is a prediction market, which means you trade on the outcome of real-world events: who wins an election, whether a team wins, where Bitcoin closes the year. Instead of a price chart, you buy shares in a “Yes” or “No” outcome, and the price acts like a probability. It has become one of the most talked-about platforms in crypto, especially around elections. This guide explains what Polymarket is, how it works, what you can bet on, who can use it, and the risks, with links to step-by-step guides for each part.

A responsible-use note. This is general education, not betting or financial advice. Prediction markets are high-risk event speculation, you can lose your entire stake, and legality varies by region. Only use money you can afford to lose, check your local laws, and read our risk disclaimer.

Key takeaways

• Polymarket is a prediction market: you trade on real-world event outcomes, not assets.
• Shares are priced between 0 and 1 dollar, which works like a probability. The correct side pays 1 dollar.
• The global version runs on Polygon and settles in USDC; it is geoblocked for US users.
• Polymarket US (a CFTC-regulated exchange via QCX) launched in December 2025 for US residents.
• It is high-risk event speculation, not investing. You can lose your whole stake.

What Polymarket actually is

Polymarket is a prediction market platform. Rather than trading coins or stocks, you trade on whether a specific event will happen. Each market is a clear question with a deadline and a yes-or-no resolution, for example “Will [event] happen by [date]?” The global Polymarket runs on the Polygon blockchain and uses the USDC stablecoin for everything, so you deposit, trade, and withdraw in USDC.

The appeal is that the prices double as a live probability estimate from people putting real money behind their views, which is why journalists and traders watch Polymarket odds around big events. For the full platform overview, see our Polymarket review.

How Polymarket works

Every market has two sides, Yes and No, and each is a share priced between 0.00 and 1.00 dollars. The two prices add up to about 1 dollar, and the price is the market’s estimated probability:

• A Yes share trading at 0.60 implies the market thinks there is about a 60 percent chance the event happens.
• You buy the side you believe in. If you are right at resolution, each share pays 1.00 dollar. If you are wrong, it pays 0.

A quick example. You buy 100 Yes shares at 0.60 dollars, spending 60 dollars. If the event happens, you get 100 dollars (a 40 dollar profit). If it does not, you get nothing and lose your 60 dollars. You can also sell your shares before the deadline if the price moves in your favor, locking in a gain or cutting a loss. Markets resolve through the UMA oracle, explained in our Polymarket UMA oracle guide.

What you can bet on

Polymarket lists thousands of event contracts across many categories:

• Politics and elections, its most famous category, covered in our election betting guide.
• Sports, from match results to season outcomes.
• Crypto, like whether a coin hits a level by a date.
• Economics and current events, from rate decisions to cultural moments.

The two Polymarkets: global vs US

This is the part most explainers get wrong in 2026, because there are now two products under one brand:

• Polymarket (global). The original crypto-native exchange on Polygon, settling in USDC, with thousands of markets. It remains geoblocked for US users as a condition of its 2022 settlement with the CFTC.
• Polymarket US. A separate, CFTC-regulated exchange operated by QCX LLC, which launched in December 2025 after Polymarket acquired a licensed venue. It is the version US residents can lawfully use, rolled out in phases.

So “can Americans use Polymarket” now has a nuanced answer: not the global site, but yes the regulated US product. We cover this in detail in can Americans use Polymarket, and EU access in Polymarket for EU users. Wherever you are, check your local laws first.

How to get started

If it is available and legal where you are, the path is short:

1. Sign up. Create an account. See how to sign up on Polymarket.
2. Fund it. On the global version, deposit USDC on Polygon. See how to deposit USDC on Polymarket.
3. Trade. Pick a market and buy the outcome you want. See how to trade on Polymarket.
4. Cash out. Sell or wait for resolution, then withdraw. See how to withdraw from Polymarket.

When you are ready, you can open Polymarket. Start small and treat it as high-risk.

Fees, KYC, and safety

• Fees. Polymarket’s fee model is light compared with a typical exchange, but it is not free of cost. See Polymarket fees explained.
• KYC. Requirements depend on the product and your region. See Polymarket KYC requirements.
• Safety. It is established but not risk-free. See is Polymarket safe.

The risks you must accept

• You can lose your whole stake. A losing position goes to zero. This is event speculation, not investing.
• Resolution risk. Markets settle through the UMA oracle, which has rules and occasional disputes. Read the market terms.
• Legal and region risk. Prediction markets are restricted or banned in many places. The global site geoblocks the US, and rules vary worldwide.
• Liquidity. Thin markets can be hard to exit at a fair price.
• It is addictive by design. Fast, event-driven betting can become compulsive. Set limits and walk away.

Bottom line

Polymarket is a prediction market where you trade on real-world events using shares priced like probabilities, with the correct outcome paying 1 dollar. The global version runs on Polygon in USDC and is geoblocked for the US, while Polymarket US is a separate CFTC-regulated exchange that opened to US residents in December 2025. It is genuinely interesting and genuinely high-risk: you can lose your entire stake, and it is speculation, not investing. If it is legal where you are and you want to try it, start small, and you can open Polymarket.

This article is general information, not betting or financial advice. Prediction-market trading is high-risk, you can lose everything you stake, and legality varies by region. Read our risk disclaimer, check your local laws, and never use money you cannot afford to lose.
