Americans Are Trading Billions of Dollars on Polymarket's Offshore Platform Despite Bans

POLYMARKET'S OFFSHORE PLATFORM AND US TRADING VOLUME

Polymarket, a crypto-based prediction market platform, has recently come under scrutiny due to its significant trading volume originating from the United States. According to a study conducted by Rutgers University statistician Harry Crane, approximately 30 percent of the trading volume on Polymarket is attributed to US-based users. This statistic is particularly striking considering that these individuals are not legally permitted to access the platform. The study estimates that US traders funneled between $10.6 billion and $26.7 billion through Polymarket, highlighting the platform's role as a major player in the offshore trading space.

The findings reveal that Polymarket's offshore platform serves as a hub for US traders seeking to engage in prediction markets, particularly in areas such as sports and political events. The high volume of trading activity from the US raises questions about the legal implications of such engagement and the measures that may be taken by regulators to address this issue. The data suggests that Polymarket has become a popular choice for those looking to capitalize on market predictions, despite the legal barriers that exist in the United States.

HOW AMERICANS ARE TRADING BILLIONS ON POLYMARKET DESPITE LEGAL BANS

Despite the legal restrictions surrounding online gambling and prediction markets in the United States, Americans are finding ways to trade billions on Polymarket's offshore platform. The study by Crane indicates that US-based traders have been able to circumvent these legal barriers, allowing them to participate in a marketplace that is otherwise off-limits. This phenomenon raises important questions about the effectiveness of current regulations and the potential need for reform in the face of evolving technology.

One of the key factors enabling this trading activity is the decentralized nature of cryptocurrency and the anonymity it provides. Many traders are likely leveraging digital wallets and cryptocurrencies to obscure their identities, making it difficult for regulators to track their activities. Additionally, the allure of high-stakes betting on events such as elections and sports matches may be driving US traders to engage with Polymarket, despite the risks associated with doing so.

THE IMPACT OF US-BASED TRADERS ON POLYMARKET'S MARKETPLACE

The presence of US-based traders on Polymarket has a profound impact on the platform's marketplace dynamics. With US traders accounting for a significant portion of the trading volume, their participation influences market liquidity and pricing. The study found that many of the highest-volume markets on Polymarket are centered around US-centric events, which further underscores the importance of this demographic to the platform's overall success.

Moreover, the concentration of US traders in specific market segments, such as sports betting, suggests that Polymarket has effectively tapped into a lucrative audience. This influx of US capital not only enhances the platform's trading volume but also attracts more users, creating a self-reinforcing cycle of engagement. However, the reliance on US-based traders also poses risks, as any regulatory actions taken against Polymarket could significantly impact its operations and user base.

ARE POLYMARKET'S US-CENTRIC MARKETS DRIVING BILLIONS IN TRADING ACTIVITY?

The analysis of Polymarket's trading activity reveals that its US-centric markets are indeed driving billions in trading activity. The Rutgers study highlights that US-based traders are particularly active in markets related to US elections and sporting events, with estimates suggesting they account for nearly half of the activity in these segments. This level of engagement indicates that Polymarket has successfully captured the interest of a demographic eager to participate in predictive trading.

This trend raises questions about the sustainability of such trading activity, especially in light of potential regulatory scrutiny. As more US traders flock to Polymarket for its unique offerings, the platform may face increasing pressure from authorities to comply with local laws. Nonetheless, the current trading volume suggests that US-centric markets are a vital component of Polymarket's business model, driving significant revenue and user engagement.

ANALYZING THE RUTGERS STUDY ON POLYMARKET AND US TRADERS

The Rutgers study conducted by Harry Crane provides valuable insights into the trading behaviors of US-based users on Polymarket. By analyzing data from May 2025 to April 2026, Crane was able to estimate the substantial volume of trades originating from the US, which has important implications for both the platform and regulatory bodies. The findings indicate that a considerable number of US traders are actively participating in Polymarket's prediction markets, despite the legal risks involved.

Crane's research not only sheds light on the extent of US engagement with Polymarket but also raises concerns about the regulatory landscape surrounding offshore trading platforms. The study emphasizes the need for regulators to adapt to the changing dynamics of online trading and consider the implications of allowing such platforms to operate without oversight. As the popularity of prediction markets continues to grow, the findings from this study may serve as a catalyst for discussions on how to best regulate these emerging marketplaces in a way that protects consumers while fostering innovation.
