Polymarket's Strategic Move to Japan: A Long-Term Regulatory Challenge

Facing US legal pressure, Polymarket is now looking to Japan as its next major regulatory battleground. The platform is reportedly targeting approval by 2030 and has already started a lobbying effort, while appointing a local representative to support the push.

That matters because Japan is not an easy market to enter. With some of the strictest gambling rules globally, any path forward will depend on how Japanese authorities choose to classify prediction markets under the country’s legal framework.

Mike Eidlin, head of Japan at Jupiter, is said to be leading the local effort, and Polymarket is reportedly pointing to meaningful organic interest from users in Japan as part of its case. In other words, this is not just about market access — it is about building a regulatory narrative that can survive scrutiny in one of the toughest jurisdictions in the world.

The 2030 target also tells us something important: this is a long-duration lobbying strategy, not a quick expansion play. A multiyear approval timeline increases execution risk, political uncertainty, and the chance that product design itself could be constrained by regulatory definitions.

This signals a structural test for how advanced economies may classify blockchain-based prediction products.

If Polymarket can secure legitimacy in Japan, the result would carry weight far beyond one market and could become a reference case for other regulators weighing prediction markets, blockchain futures contracts, and gambling-law boundaries.
