France has moved directly against Polymarket, with Reuters reporting that the country’s gambling regulator ordered internet providers to block access to the site. The regulator said Polymarket promoted an illegal gambling and betting offering, while also citing risks of significant losses and market manipulation. For prediction-market watchers, the action is another reminder that rapid user growth is running into a patchwork of national gambling, finance, and consumer-protection rules.
France targets Polymarket access
Reuters’ report puts France among the jurisdictions taking a harder line on crypto-native prediction markets. The regulator’s concerns go beyond licensing status: it explicitly pointed to potential market manipulation and the possibility of users suffering large losses.
That framing matters because it suggests regulators may treat prediction markets not only as gambling-law questions, but also as venues where information integrity and consumer harm are central issues. For Polymarket, access blocks can limit local participation and complicate its broader push to be seen as a mainstream information market rather than an offshore betting product.
Kalshi faces scrutiny over Trump speech markets
CBS News reported that White House teleprompter operator Gabriel Perez made more than $100,000 on Kalshi mention-market bets tied to President Trump’s speeches. According to CBS, Kalshi froze the profits and referred the matter to the CFTC.
The episode cuts to a core challenge for event-contract platforms: markets based on official speeches, announcements, or government actions can be vulnerable to people with privileged access. Even when a platform responds by freezing funds and notifying regulators, the incident raises questions about surveillance, market design, and whether some contracts are too exposed to insider-information risks.
Kalshi pilots biotech outcome markets
STAT reported that Kalshi launched a pilot for biopharma prediction markets covering clinical trial outcomes and FDA approvals, in partnership with AppliedXL.
This is a notable expansion into a highly specialized information market. Clinical trials and regulatory decisions already move public companies and shape investor sentiment, but putting those outcomes into regulated prediction contracts could attract biotech analysts, healthcare investors, and industry participants. It also raises the stakes for accuracy, data access, and guardrails around material nonpublic information.
Market pulse: politics, esports, and sports stay active
The busiest Polymarket events by 24-hour volume included “Next Prime Minister of Ethiopia?” at about $9.3 million, an Esports World Cup League of Legends match at about $8.4 million, and Spain vs. Argentina exact score at about $5.0 million. The mix shows how broad the market menu has become, even as regulators increasingly scrutinize access and legality.
Why it matters
This week’s stories point in two directions at once: prediction markets are expanding into more consequential categories, while regulators and platforms are being forced to confront legality, manipulation, and information-access risks. Growth is still the headline — but compliance is becoming the constraint.
