Romania has issued a ban on Polymarket, a blockchain prediction platform, citing illegal crypto betting operations involving over $600 million in wagers related to recent national elections. The National Office for Gambling (ONJN) determined that the platform’s activities fall under gambling regulations and require a local license, which Polymarket currently lacks. This action highlights the challenges facing blockchain-based platforms navigating regulatory hurdles across jurisdictions, potentially impacting liquidity and trading volumes in affected markets. The ban follows similar actions taken against Polymarket in France, Belgium, and the U.S., illustrating persistent compliance issues for the platform.
