The study provides concrete, quantitative data on the scale of US offshore participation, and the CFTC's aggressive stance is well-documented. However, the exact speed and efficacy of regulatory enforcement remain variable.
Executive summary
According to a study commissioned by the Coalition for Prediction Markets—an industry group including regulated operators Kalshi, Crypto.com, and Coinbase—U.S. citizens traded between $11 billion and $34 billion on offshore prediction markets during a 12-month period ending in April 2026. The study, authored by Rutgers professor and CFTC Innovation Advisory Committee member Harry Crane, highlights that despite official bans on U.S. users, offshore platforms continue to attract substantial American capital. Polymarket, the largest offshore prediction market, reportedly saw between $10.6 billion and $26.7 billion of its $55.6 billion trailing 12-month trading volume originate from U.S. users, representing up to 30% of its total activity.
The immediate implication is an intensified push by regulated domestic competitors and the Commodity Futures Trading Commission (CFTC) to curb offshore access. While Polymarket has slowly rolled out its regulated "Polymarket U.S." platform, which has generated approximately $5 billion in notional trading volume to date, the vast majority of U.S. capital remains on unregulated platforms. This discrepancy has drawn sharp criticism from domestic operators who argue that offshore platforms bypass essential anti-money laundering (AML) controls, customer verification, and market integrity standards.
Why it matters
From a market-structure and capital-flow perspective, the study exposes the sheer scale of capital currently operating outside the U.S. regulatory perimeter. Polymarket's operations primarily rely on stablecoins (specifically USDC) settled on the Polygon network. Consequently, a significant portion of this $34 billion in offshore trading volume directly drives transaction fees, active addresses, and liquidity depth within the Polygon and broader Ethereum Layer-2 ecosystems. If regulatory enforcement successfully blocks U.S. users via stricter VPN detection or smart-contract-level geoblocking, we could see a noticeable contraction in on-chain transaction volume and stablecoin velocity on these networks.
Conversely, the primary beneficiaries of an aggressive regulatory crackdown would be domestic, fiat-integrated platforms like Kalshi or fully compliant crypto-native alternatives. However, these regulated platforms operate under strict CFTC constraints, which currently limit the types of contracts they can offer. The CFTC's proposed rules to ban contracts on controversial topics like war or political assassinations could stifle the very speculative appeal that drives offshore volumes. Therefore, a forced migration of liquidity from offshore to regulated domestic platforms is unlikely to be a 1:1 transfer; instead, a significant portion of this speculative liquidity may simply exit the prediction market sector entirely, reducing overall crypto-market liquidity.
Furthermore, the political battle over jurisdiction—highlighted by CFTC Chairman Mike Selig's aggressive stance and Senator Elizabeth Warren's scrutiny of the regulator's resources—suggests that prediction markets will remain a primary battleground for crypto regulation. The outcome will set a critical precedent for how the U.S. governs decentralized protocols that serve U.S. users through offshore entities.

What it means for you
The likely scenarios — and the practical takeaway.
A clear path to regulated integration could legitimize prediction markets, bringing institutional capital and substantial trading volume to compliant platforms. If Polymarket successfully transitions its user base to its regulated U.S. entity without losing liquidity, it could establish a compliant blueprint for other DeFi protocols. This transition would likely boost on-chain transaction volume and demand for settlement assets like ETH and POL, as institutional market makers gain the legal clearance to provide deep liquidity. Under these conditions, we would expect a sustained increase in stablecoin inflows to regulated smart contracts, supporting utility-driven token valuations.
The most likely outcome is a prolonged period of regulatory friction, where offshore platforms face escalating compliance costs and geoblocking mandates, while domestic regulated platforms capture only a fraction of the displaced volume. Based on historical precedents of offshore exchange crackdowns, U.S. users will likely face increasingly sophisticated barriers to accessing offshore liquidity pools, causing a gradual decline in unregulated trading volume. However, because regulated platforms like Kalshi are legally restricted from offering the highly speculative and global contracts that drive offshore demand, a large portion of the $34 billion in estimated U.S. volume will simply dissipate rather than migrate. This will result in a net reduction in on-chain transaction volume for networks like Polygon, though the impact will be gradual rather than an abrupt shock. Polymarket U.S. will likely see modest growth in trading volume, but it will struggle to replicate the deep liquidity of its offshore counterpart due to strict KYC and contract limitations. This thesis would be invalidated if the CFTC loses its jurisdictional battles in federal court, allowing offshore platforms to continue operating with minimal domestic enforcement.
An aggressive CFTC crackdown, backed by political pressure from lawmakers like Senator Elizabeth Warren, could severely disrupt the sector. If the CFTC successfully implements bans on high-volume contract categories and enforces strict IP and wallet-level blocking, offshore trading volume could collapse without a corresponding rise in domestic regulated volume. This would drain billions of dollars in active liquidity from the Polygon ecosystem, leading to a sharp decline in network transaction fees and active addresses. Such a regulatory worst-case scenario would likely depress sentiment across Web3 protocols, leading to capital flight and lower trading volumes across decentralized applications.
Your takeaway
Traders should monitor Polygon (POL) network transaction volumes and active addresses as a proxy for prediction market health, while preparing for localized liquidity dampening if CFTC enforcement intensifies.

What would change our view?
Real analysis is falsifiable — these are the measurable signals that would move our scenario, in either direction.
Shifts us Bullish
- Polymarket US weekly trading volume exceeds $1 billion
- Federal court rules CFTC lacks authority to ban political prediction contracts
Shifts us Bearish
- CFTC issues formal cease-and-desist orders to major offshore prediction market operators
- Polygon daily active addresses drop by more than 20% over a 30-day period
Key insight
The $34 billion in offshore prediction volume represents a highly concentrated regulatory target; a successful crackdown will likely extinguish, rather than migrate, a significant portion of this on-chain liquidity.

Implementation of proposed CFTC rules on contract bans could begin restricting the scope of legal prediction markets, capping volume growth.
What could invalidate this read — known unknowns, not predictions.
- Unexpected legal victories for prediction markets that strip the CFTC of regulatory authority.
- Rapid technological workarounds that allow US users to completely bypass geoblocks without detection.
- A sudden surge in non-US volume that offsets any potential loss of US capital.
Bottom line
The most likely outcome (55% probability) is a gradual reduction in offshore prediction market liquidity as the CFTC escalates enforcement, with regulated domestic platforms failing to fully capture the displaced volume due to strict contract limitations. The single biggest risk to this outlook is a sweeping judicial ruling that strips the CFTC of its jurisdiction over prediction markets, which would trigger an unregulated volume surge. Traders should closely watch weekly trading volume on Polymarket's regulated U.S. platform versus its offshore entity, alongside Polygon network transaction fees, to gauge the rate of capital migration.
