Polymarket, the decentralized prediction market platform, logged its first $10 billion in monthly trading volume in March 2026, crossing a milestone that comes as the company pushes into new regulatory territory — Japan. The platform has appointed a local representative and launched a formal lobbying campaign aimed at securing government authorization by 2030.
Volume milestone in a volatile year
The $10 billion figure marks a sharp climb for a platform that was still handling a fraction of that amount just a couple of years ago. Polymarket doesn't break out monthly user numbers, but the surge in trading activity points to broader adoption of decentralized prediction markets as tools for hedging and speculation on everything from election outcomes to central bank rate decisions.
Much of the March volume was concentrated on U.S. political contracts and macroeconomic events, according to data publicly visible on the blockchain. The platform runs on smart contracts, meaning all trades are recorded on-chain and settlement is automated. That transparency has drawn both retail traders and institutional players looking for alternatives to traditional derivatives.
Why Japan is next
Polymarket is betting that Japan's regulatory framework, which is strict but predictable, can offer a pathway to legitimacy. The company has already appointed a local representative — a step required under Japanese law before any foreign crypto-related business can begin formal licensing talks.
The lobbying effort is focused on the Financial Services Agency (FSA), Japan's main financial regulator. Polymarket is asking for authorization to operate as a licensed prediction market platform, which would let it offer contracts tied to elections, sports, and economic indicators to Japanese residents. The goal is to receive approval by 2030, a timeline that reflects the slow, deliberate pace of Japanese regulatory review.
The regulatory challenge
Prediction markets exist in a gray zone in many countries. In the U.S., the Commodity Futures Trading Commission has been split on whether to treat event contracts as gambling or as legitimate financial instruments. Polymarket has faced scrutiny there but has continued operating by restricting access in certain jurisdictions.
Japan presents a different set of rules. The country's Payment Services Act and Financial Instruments and Exchange Act define what counts as a derivative or a gambling product. Polymarket's team is working to frame its contracts as financial derivatives, not betting, to fit within the existing legal categories. The local representative will be key in those talks.
What happens next
Polymarket's lobbying documents, filed with Japanese authorities, propose a phased rollout: first, a sandbox period under FSA supervision, then a full license application. The company has not said when it expects the sandbox to begin, but the 2030 target suggests it's planning for a multiyear process.
For now, Japanese users can still access the platform via VPN, but that workaround carries legal risk. Polymarket is hoping formal authorization will bring them out of the shadows — and add another country to its growing list of regulated markets. The FSA has not yet publicly commented on the proposal.
