Bitbank Warns Users Over Polymarket-Linked Crypto Transfers in Japan

Bitbank, one of Japan’s largest crypto exchanges, has warned customers that accounts involved in transactions linked to prediction market platforms such as Polymarket could face restrictions or suspension. The exchange said the move is intended to address potential conflicts with Japan’s gambling laws.

According to the notice, users who send or receive funds connected to prediction market services may lose access to important account functions, including logins, deposits, withdrawals and cryptocurrency trading. Bitbank also stated that it would not be responsible for any losses resulting from account suspension measures.

Gambling Law Concerns Drive Exchange Warning

The exchange explained that prediction market platforms often allow users to place bets on future events, including election outcomes, sports results and other public developments. When financial rewards are involved, such activities could potentially be viewed as gambling under Japanese law.

Bitbank did not mention any specific request from regulators or government agencies. However, the company urged customers to be cautious when using third-party services and avoid activities that could lead to legal problems.

Polymarket Expansion Faces Regulatory Questions

The warning comes at a time when prediction markets are facing increased scrutiny in several countries. Regulators in multiple jurisdictions have examined platforms such as Polymarket and Kalshi over concerns related to gambling regulations.

Polymarket currently lists Japan among the countries where access is restricted. However, the company indicated earlier this year that it was exploring opportunities to expand into the Japanese market. Bitbank’s latest warning suggests that cryptocurrency firms in Japan are taking a cautious approach as legal questions surrounding prediction markets remain unresolved.

For now, the exchange’s message serves as a reminder that users should carefully consider the legal implications of transferring funds to and from prediction market platforms.
