Polymarket is a New York-based cryptocurrency prediction market platform founded in 2020 that enables users to buy and sell shares tied to the outcome of future events. The platform structures these markets as binary yes-or-no questions, where participants trade shares priced between $0 and $1 using the USDC stablecoin through the Polygon blockchain. The price of each share reflects the market’s collective estimate of the probability that a particular event will happen. Shares in correct outcomes settle at $1 upon resolution, while incorrect shares become worthless.

Polymarket is banned in several countries as an unlicensed offshore gambling platform. It had been officially off-limits to U.S. users since 2022 after a settlement with the Commodity Futures Trading Commission during the Biden administration, but it received CFTC approval in December 2025 and subsequently launched its mobile platform for sports and proposition markets under federal oversight.

History

Polymarket was conceived in 2020 by the entrepreneur Shayne Coplan as a decentralized prediction market platform allowing users to use cryptocurrency to trade on the outcome of real-world events ranging from elections and sports to financial news and pop culture. Early on, Coplan was joined by a cohort of engineers, venture capitalists, and market specialists intent on building a censorship-resistant protocol for information trading. Peter Thiel and Vitalik Buterin raised about $70 million in funding for Polymarket.

Polymarket operates using a hybrid order book that matches trades off-chain, but handles settlement on-chain, ensuring transparency and auditability. The platform is non-custodial—users retain possession of their funds until each market resolves. There is no house; trades are matched between users, and shares can be bought or sold at any time before settlement as market sentiment shifts. Every Polymarket trade is recorded on a public blockchain.

Since its launch, Polymarket has attracted significant trading activity and has been referenced as an alternative indicator in political coverage and financial discussions. Market participants have included institutional investors and researchers who use its odds as real-time probabilistic gauges. For instance, major financial institutions have incorporated Polymarket’s predictions into research and trading strategies tied to major elections.

In 2024, betting on the outcome of the 2024 presidential election became Polymarket’s most popular offering, with about $2.7 billion in trading volume on the main market, but open interest was only about $330 million, according to an analysis on the data platform Dune. By Election Day 2024, Polymarket had become widely cited by news organizations and political commentators as an alternative to traditional polling. The company's successes include predicting that President Biden would drop out of the 2024 presidential election.

According to an analysis by Chaos Labs, about one-third of the volume on Polymarket for the U.S. presidential election winner’s market appeared likely to be wash trading. Fortune Magazine reported on October 30, 2024 that Polymarket was "rife with fake ‘wash’ trading," according to researchers.

Polymarket has faced regulatory challenges. In January 2022, the Commodity Futures Trading Commission (CFTC) fined the company $1.4 million for running an unregistered facility and offering binary options on world events and forced it to exit the U.S. The CFTC required Polymarket to wind down non-compliant U.S. markets and blocked U.S.-based users, pushing operations offshore. Substantial cooperation with regulators led to a reduced penalty, and Polymarket soon appointed former CFTC Chair J. Christopher Giancarlo as chairman of its advisory board. The platform continued its huge growth overseas in spite of the ban, processing more than $6 billion in bets during the first half of 2025 alone and gaining prominence by accurately predicting Donald Trump’s 2024 presidential victory.

On December 4, 2025, Bloomberg reported that Polymarket had been recruiting new staff members for an internal market making team that could face off against customers on the company’s exchange, even though its rival Kalshi had been criticized for introducing a similar feature.

QCX Acquisition

In 2025, a landmark acquisition saw Polymarket purchase the CFTC-licensed exchange QCX LLC for $112 million, a move that opened a path to U.S. market re-entry by enabling Polymarket to secure a Designated Contract Market license. The license allows it to self-certify markets for U.S. users, including sports and election betting.

This expansion was followed by a strategic investment and board appointment of Donald Trump Jr., helping Polymarket navigate a shifting regulatory environment and further linking the platform’s fortunes to national political debate.

Intercontinental Exchange investment

On October 7, 2025, Intercontinental Exchange Group Inc. announced it would invest up to $2 billion in Polymarket in a deal that valued Polymarket at about $8 billion. ICE also said it would become a global distributor of Polymarket’s event-driven data. On March 27, 2026, ICE announced that, as part of the previously announced investment arrangement, ICE had completed a new $600 million direct cash investment in Polymarket, which is part of an equity capital fundraising by Polymarket. ICE also said it expects to make purchases of up to $40 million of Polymarket securities from certain existing holders. With the additional $600 million direct investment and the anticipated purchases of Polymarket securities, ICE will have completed its obligations under the investment arrangement with Polymarket.

Products & Services

Polymarket is structured around peer-to-peer trading of binary and categorical event outcomes, using smart contracts and stablecoins for transparency, settlement, and market-making. Central to its platform are the following:

• Binary markets (“Yes/No”): Each outcome is collateralized by USDC stablecoin, settling at $1 for correct and $0 for incorrect predictions.
• Categorical markets: Multiple choice outcome trading, suitable for contests such as elections or sports league results.
• Share-based trading: Users purchase and sell shares at market-determined probability prices, with active trading before, during, and after significant events.
• Decentralized oracle system: Utilizes UMA’s Optimistic Oracle for disputed outcomes, penalizing dishonest resolution actors and increasing resiliency against manipulation.
• Analysis tools: In-app charts, data feeds, and market widgets for integrating real-time odds into media, research, and decision-making applications.
• Third-party wallet integration: Crypto AI agents and wallet services facilitate market interaction via credit card and wire transfer as well as cryptocurrency.

Polymarket integrates deeply with crypto-native infrastructure and supports the trading needs of a wide range of users—hedgers, speculators, researchers, and journalists—while maintaining accessibility through low transaction fees, open APIs, and privacy-oriented design.

Risk Management

Polymarket relies on blockchain transparency and decentralized oracles for internal risk management, aiming to minimize third-party custodial risk and market manipulation. By leveraging smart contracts and external verifiers, event resolution is designed to be robust against single-point failure and collusion.

Regular audits of transaction integrity and codebase updates are conducted in partnership with third-party blockchain analysts. The platform’s terms of service include strict prohibitions against insider trading, wash trading, and collusion. Dispute resolution via decentralized oracle consensus is employed in rare cases involving unclear market outcomes or suspicious activity. Recent years have seen the addition of compliance and anti-money laundering modules to meet evolving U.S. regulatory standards.

In March 2026, Polymarket enlisted the software maker Palantir Technologies for assistance in monitoring sports contracts, according to a report. Palantir and TWG AI will help Polymarket identify, prevent and report suspicious activity, according to Bloomberg.

Controversies

Polymarket’s explosive growth has also brought regulatory and reputational challenges. In 2022, the CFTC fined and partially shuttered Polymarket’s U.S. operations, citing unauthorized offer of binary options and a lack of Swap Execution Facility licensing. Subsequent investigations by the CFTC and Department of Justice in 2025 addressed allegations of ongoing unauthorized U.S. user activity, culminating in the acquisition of QCX and a formal regulatory entry route.

Analysts from Chaos Labs and Inca Digital have publicly highlighted evidence of widespread wash trading and inflated volume reporting on Polymarket, particularly during the 2024 presidential election. Internal platform data conflated total shares traded with dollars, leading to a perceived overstatement of actual market depth and liquidity. Polymarket has defended its transparency, stating that blockchain data remains publicly auditable and that terms explicitly prohibit market manipulation.

Other controversies have centered on the accuracy and influence of market-driven forecasts. Critics have argued that prediction markets may be susceptible to well-funded actors or potentially misrepresentative crowd sentiment. The platform remains the subject of ongoing regulatory and academic analysis, as the efficacy and fairness of prediction markets become further entwined with the financial industry and political decision-making.

Critics have also questioned the legality and ethics of betting on military conflicts. In early 2026, wagers on geopolitical questions on Polymarket his a record $425.4 million as traders bet on the US-Israeli strikes on Iran, while blockchain analysts flagged suspicious activity and lawmakers called for a crackdown. US regulations are broadly understood to prohibit financial contracts tied to war, but Polymarket’s main exchange operates offshore, outside the oversight of US regulators. Israeli authorities filed charges against two people for using classified information to bet on Polymarket. But these problems did not discourage Polymarket from expanding the array of bets on the conflict. Some of the most actively traded contracts include one on when the Iranian regime will fall, with more than $30 million wagered, and one on who the next supreme leader is going to be, which attracted more than $16 million.

In July 2026, Bloomberg reported that researchers at Stanford University identified signs that traders might be manipulating one of Polymarket’s popular Bitcoin prediction markets by briefly influencing the cryptocurrency’s price used to decide the wagers. In the report, the researchers argue that prediction markets on financial assets are vulnerable to manipulation because participants can trade the very asset that determines whether they win or lose the bet. Bloomberg also said that "the paper does not prove that the trading necessarily came from Polymarket users who stood to gain from momentary moves in Bitcoin’s price."

In September 2026, it was reported that fraudsters had tried to steal at least $10 million through Polymarket’s U.S. platform in February by making bets with stolen debit cards and attempting to withdraw the winnings onto "clean" cards or accounts they controlled. Shayne Coplan reportedly told his staff to focus on growth now and deal with regulatory fines later.
