Portugal Blocks Polymarket Over Political Bets

Over €4 million poured into presidential election markets right before results dropped, amid suspicions of insider trading from leaked exit polls, with total volume surpassing €110 million.

This echoes France, Belgium, and Poland’s prior bans, as governments chase decentralized platforms hard to police.​

Betting Boom Sparks Crackdown

Prediction markets like Polymarket let users trade shares on event outcomes, yes or no bets settled in USDC stablecoin, often pricing news faster than polls. SRIJ views the unlicensed platform as straight gambling, illegal under Portugal’s 2015 laws that bar political wagers and limit approved bets to sports or casino games. Hours before polls closed, odds swung wildly: Socialist candidate António José Seguro’s win probability jumped from 60% to 95%, while rivals tanked, matching private exit poll leaks around 6 p.m. that journalists accessed first. Regulators gave a 48-hour shutdown notice Friday, but as of Monday the site lingered accessible, prompting potential ISP blocks.​

The clash fits a broader pushback: prediction markets hit $6 billion weekly volume last week, led by Kalshi ($2.15B), OpinionLabs ($1.94B), and Polymarket ($1.76B). Portugal joins over 30 restricted countries, amid U.S. probes into election bets. A real example: U.S. users wagered billions on 2024 election odds, where Polymarket nailed Trump’s chances better than Vegas books.
