Polymarket International Review 2026: Event Trading on Polygon

Polymarket describes itself as the world's largest prediction market. Users trade on the outcomes of real-world events and build a portfolio from their forecasts. DefiLlama lists it in the Prediction Market category on Polygon, with about $316 million in TVL and a listing date of 26 October 2021.

The homepage shows markets across politics, sports, crypto, esports, finance, geopolitics, tech, culture, economy and weather. Featured markets display odds, trading volume and end dates, plus linked news coverage. Navigation also lists Combos and Perps, which suggests products beyond simple yes/no markets.

This international version is separate from the US offering. The homepage tells US users to go to a different site, and public reporting says Polymarket operates through separate legal entities, with the US one run by a CFTC-regulated contract market. The project does not say what licence, if any, covers the international site.

Polymarket lists questions about future events, such as who will win an election. Each possible outcome has shares priced between 0% and 100%. A price of 92% means the market currently implies about a 92% chance.

Users buy shares in the outcome they believe will happen and can sell before the market ends. When the event resolves, shares in the correct outcome pay out and shares in the wrong ones go to zero. The profit comes from buying at a price lower than the eventual result.

DefiLlama lists the protocol on Polygon, so trading activity settles on that chain. The project does not detail the order book, settlement token or resolution process, so readers should check those on the platform.

The project does not publish a trading fee schedule, deposit costs or withdrawal costs. Users would see current fees on the platform at the point of trading and in its documentation.

One fact that does touch on fees is the referral page, which says referrers earn 10% of fees from direct referrals and 5% from indirect referrals. That implies that fees exist, but not what they cost. Because the market is on Polygon, network costs for on-chain actions may also apply, though the project does not give amounts.

DefiLlama lists two audits, but the project does not name the auditors or show findings, so readers should not treat the audit count as a guarantee. As with any on-chain market, smart-contract risk, oracle or resolution risk and counterparty risk apply. Public sources report no hack or shutdown.

On regulation, public sources say Polymarket operates globally through separate legal entities and that the US version is operated by a CFTC-regulated contract market. No licence is stated for the international site. Prediction markets can count as gambling in some places, so check that they are legal where you live. This is for adults aged 18 or older. Set limits, never stake money you cannot afford to lose, and seek help if betting stops being fun.

This is for adults who follow news, politics, sports or crypto and want to take a position on outcomes, or who read the odds as a forecasting signal. It is not for anyone in a region where such markets are restricted, or for people who cannot afford to lose the money they stake.
