Americans are secretly trading billions of dollars on Polymarket's crypto prediction platform despite a federal ban that's supposed to keep them out. A new study provides the first quantitative estimate of just how many US users are circumventing the block, revealing a massive regulatory evasion story that raises fresh questions about enforcement in the crypto prediction market space. The findings land as Polymarket faces mounting scrutiny over insider trading allegations and compliance failures.
Polymarket blocked Americans from its crypto-powered prediction market back in 2022 after settling charges with the CFTC. But according to new research reported by Wired, that ban hasn't stopped US traders from pouring billions into the platform.
The study marks the first time researchers have quantified the scale of American participation on Polymarket since the platform officially went offshore. While exact figures weren't disclosed in initial reports, sources familiar with the research suggest the numbers represent a significant portion of Polymarket's overall trading volume, raising uncomfortable questions about how effectively crypto platforms can actually enforce geographic restrictions.
Polymarket settled with the Commodity Futures Trading Commission for $1.4 million in January 2022, agreeing to block US users after regulators determined it was operating an unregistered derivatives exchange. The platform lets users bet on real-world events using cryptocurrency, from election outcomes to celebrity news. In theory, Americans can't access it anymore. In practice, the blockchain-based platform has proven remarkably porous.
The research suggests users are bypassing Polymarket's geo-blocking through VPNs, offshore wallets, and other technical workarounds that obscure their true location. Because Polymarket transactions happen on the Polygon blockchain and don't require traditional identity verification, enforcement relies heavily on IP-based blocking, which sophisticated users can easily circumvent.
"These platforms operate in a gray zone where the technology fundamentally resists geographic boundaries," one blockchain researcher told Wired. The anonymous nature of crypto transactions makes it nearly impossible to definitively trace trades back to specific individuals or locations without subpoenaing exchange records or wallet providers.
The timing is particularly awkward for Polymarket. The platform recently faced scrutiny over alleged insider trading when several users were arrested for manipulating markets with non-public information. Federal prosecutors have been building cases around market manipulation on prediction platforms, viewing them as potential vehicles for illegal gambling and securities violations.
Polymarket's offshore strategy mirrors moves by other crypto companies like Binance and BitMEX, which have created separate international entities to serve non-US customers while theoretically blocking American access. But those efforts have repeatedly proven leaky. Binance paid $4.3 billion in penalties in 2023 partly for failing to prevent US users from accessing its platform.
The prediction market space has exploded in recent years, with platforms like Kalshi winning regulatory approval to operate legally in the US while Polymarket and others remain in regulatory limbo. Kalshi gained CFTC approval by agreeing to extensive compliance requirements and offering only specific event contracts. Polymarket's model, offering markets on virtually anything users want to bet on, doesn't fit neatly into existing regulatory frameworks.
Crypto advocates argue that blockchain-based platforms shouldn't be subject to geographic restrictions, claiming they represent a new form of global financial infrastructure. Regulators counter that US citizens trading on unregulated platforms lack basic protections against fraud, manipulation, and unfair practices.
The billions in estimated trading volume suggests American appetite for prediction markets far exceeds what's available through approved channels. Kalshi and other legal alternatives offer limited markets compared to Polymarket's free-wheeling approach. During the 2024 election cycle, Polymarket saw massive trading volumes as users bet on everything from presidential outcomes to specific debate moments.
For the CFTC, the findings present an enforcement dilemma. The agency lacks the resources to pursue individual users accessing offshore platforms, and the decentralized nature of blockchain technology makes comprehensive blocking nearly impossible. Instead, regulators typically focus on the platforms themselves, threatening legal action against executives or seeking to cut off fiat currency on-ramps.
Polymarket didn't respond to requests for comment about the study's findings or its enforcement mechanisms. The company has previously stated it takes compliance seriously and employs multiple layers of geo-blocking to prevent US access.
But the research suggests those measures are failing at scale. As crypto prediction markets continue growing, the gap between regulatory intent and technological reality keeps widening. Billions in trading volume represents not just individual violations but a systemic enforcement failure that questions whether geographic restrictions can meaningfully apply to decentralized platforms.
The billions Americans are reportedly trading on Polymarket despite a federal ban exposes the fundamental tension between crypto's borderless architecture and traditional regulatory frameworks. As prediction markets grow and blockchain technology makes enforcement harder, regulators face an uncomfortable reality: geographic restrictions may be technically unenforceable without dramatically more invasive surveillance or cooperation from the platforms themselves. The question isn't whether Americans can access offshore crypto platforms, it's whether regulators have any realistic path to stopping them.
