Overview
- On-chain analysis firm Allium reported in early July 2026 that wallets it links to the United States accounted for about $571 million of political-market notional on Polymarket over the prior 12 months, a figure the firm calls directional because it can tag only roughly 6% of wallets.
- Polymarket blocks U.S. users by IP but the platform settles with crypto wallets and stablecoins, which lets users reach it with a VPN and no bank or account that regulators can easily stop.
- U.S.-linked wallets concentrated on geopolitical contracts rather than elections, with 46% of their volume in foreign-conflict markets and five of the twelve largest U.S. wallet markets tied to Iran-related outcomes.
- The offshore activity joins existing integrity and security concerns on Polymarket, including a stalled UMA governance vote on a large Iran market, a late‑June supply‑chain frontend hack that drained about $3 million, and allegations of undisclosed influencer promotions under CFTC and congressional scrutiny.
- Policymakers face a choice between trying to bring these markets under U.S. oversight through KYC, disclosure or on‑ramp rules and accepting that crypto rails make IP bans easy to evade, which could shift risks to investors and complicate enforcement.
