Polymarket’s US return brings new competition for retail prediction market traders

Americans can now trade predictions on everything from sporting results to major events. Polymarket wants a piece of that action, but getting regulatory approval was only its first big hurdle.

Polymarket has spent the past few years watching Americans trade predictions from the sidelines. Now it’s back, with regulatory approval and a chance to win over US traders who have developed an appetite for betting on real-world events. Getting back into the country took a $112 million deal, but getting Americans to trade on Polymarket is an entirely different challenge.

The $1.4 million settlement that kept Polymarket out

Polymarket’s American troubles began well before prediction markets became a regular talking point in financial news. In January 2022, the Commodity Futures Trading Commission (CFTC) ordered the company to pay a $1.4 million penalty for operating an unregistered event-contract trading facility.

The regulator identified more than 900 markets offered since Polymarket launched in 2020. These contracts allowed traders to take positions on the outcomes of future events, but the company lacked the registration required to offer them to American customers.

The settlement required Polymarket to wind down noncompliant markets and stop offering contracts that violated US commodities law.

Polymarket continued operating internationally, where its prediction markets attracted attention during major political events. American traders, however, remained outside its permitted customer base. Returning would require more than reopening registrations; the company needed a regulatory structure that satisfied federal requirements.

A $112 million acquisition opens the door

The solution arrived in July 2025, when Polymarket acquired QCEX for $112 million. The purchase included a federally licensed derivatives exchange and clearinghouse, giving the company an established route into the American market.

That distinction is important because event contracts fall under derivatives regulation when offered through a federally supervised exchange. Rather than seeking permission to operate its original international service in the US, Polymarket acquired infrastructure already designed to comply with American trading rules.

On September 3, 2025, the CFTC granted regulatory relief that allowed the company to move forward with its domestic plans.

The acquisition also changed the commercial picture. Polymarket had built an international audience around contracts linked to real-world outcomes, particularly elections. Its US operation could now pursue American customers through a regulated exchange rather than leaving them to follow activity from outside the market.

For retail traders, the distinction between the international platform and its American operation remains important. The available contracts and trading arrangements depend on the rules governing the US exchange.

Polymarket had secured the route back, but regulatory clearance was only the beginning of its attempt to establish a domestic trading business.

Event contracts put real-world outcomes on the trading screen

Prediction markets turn questions about future events into contracts with prices that change as traders buy and sell. A contract might ask whether a particular event will happen before a specified date, with traders taking positions based on their expectations.

A Yes contract trading at $0.65 indicates a market-implied probability of approximately 65%. When the event is resolved, a winning contract typically settles at $1, while an unsuccessful contract settles at zero.

That creates opportunities to trade changing expectations before the final result. You might buy a contract at $0.40 and sell it at $0.60 if other traders become more confident in the outcome, although prices can move against your position just as easily.

Polymarket’s US return makes this form of event trading accessible through its regulated American operation, subject to the contracts available to eligible customers.

Polymarket faces established competition for US traders

Polymarket’s return puts it in direct competition with Kalshi, which has already established a presence among American retail prediction market traders. Both platforms offer contracts tied to real-world outcomes, but attracting customers involves more than listing similar markets.

Traders can compare available contracts, transaction fees, liquidity and the difference between buying and selling prices before deciding where to place their positions. A platform offering a particular event contract does not necessarily provide the most competitive price or the easiest opportunity to exit a trade.

The competition also extends to the experience of opening and funding an account, navigating the trading interface and finding markets that match a customer’s interests. For Polymarket, its international reputation may help attract attention, but building a lasting US customer base will depend on the experience its domestic platform provides.

A welcome incentive for the US market

Polymarket’s return also brings a direct incentive for new US traders. The Polymarket bonus claimed by using the code COVERS adds $25 in trading credit after a qualifying $10 deposit, giving new accounts additional funds to explore eligible event contracts.

The additional credit increases the amount available for trading, although promotional funds are subject to conditions governing their use and withdrawal.

That distinction matters before placing a position. Event contracts carry financial risk, and a position’s value depends on the outcome being traded or the price available when it is sold.

Sports contracts bring the regulatory debate back into focus

Polymarket’s regulated return comes during a disagreement over who has authority to supervise sports-related prediction markets in the United States.

Federal derivatives regulators oversee designated contract markets, but state authorities argue that contracts based on sporting results can fall under their gambling laws. The disagreement has produced legal challenges involving the extent of federal authority and the powers retained by individual states.

The issue reached another important stage in October 2026, when the NFL supported New Jersey’s request for the US Supreme Court to examine the regulatory dispute. Thirty-eight states backed New Jersey’s position, reflecting the scale of concern among state authorities.

The commercial stakes are substantial. Prediction-market trading connected to the opening Sunday of the 2026 NFL season reached $1.8 billion across the industry, demonstrating the amount of activity generated by major sporting events.

Those figures describe the wider prediction-market industry rather than Polymarket’s individual trading volume. They nevertheless provide useful context for the environment the company has entered.

The central legal question concerns whether federally regulated event contracts can be offered nationwide when individual states classify comparable activity as gambling. A Supreme Court ruling could clarify that boundary, although the Court has yet to decide whether it will hear the case.

For Polymarket, the debate forms part of the regulatory environment surrounding its renewed American presence. Its acquisition provided a federally regulated route into the market, but broader questions about sports contracts remain unresolved.

Polymarket’s next chapter in the US

Polymarket’s return marks a substantial change from its position in January 2022. The company that paid $1.4 million to settle federal registration violations has invested $112 million in the infrastructure needed to operate within the American regulatory system.

That investment allows Polymarket to establish itself among US retail traders interested in contracts tied to real-world events. Its trading offering and introductory incentive provide practical reasons for customers to examine the service, while the ongoing legal debate will influence the environment in which it operates.

The immediate achievement is clear: Polymarket has regained a regulated route into the American market. Its next challenge is turning that access into a lasting US trading business.
