France’s gambling regulator has ordered internet providers to block Polymarket, and the prediction market says it will challenge the move in court.
- France says Polymarket is offering illegal gambling services
- Polymarket says the block was sudden and will be contested
- The bigger fight is over what prediction markets actually are
- U.S. regulators are wrestling with the same basic problem
According to Reuters, the National Gambling Authority, or ANJ, ordered French internet providers to restrict access to Polymarket on July 16. Polymarket answered with a pointed statement: “We are disappointed by the French gaming authority’s (ANJ’s) sudden decision to unilaterally block our website, we intend to challenge this decision through the legal process in France.”
That is the dispute in one sentence. France sees an illegal betting platform. Polymarket sees a legitimate market venue getting shoved into the gambling box by a regulator that does not like the cut of its jib. Same product, different legal tests. That mismatch is where the fight starts.
The ANJ said Polymarket had attracted a large French audience while offering gambling and betting services it considers illegal under national law. The regulator also warned that some contracts could be manipulated and that customers could face substantial losses. Weather contracts drew particular attention, with the ANJ raising concerns that some participants may have traded using privileged local knowledge rather than ordinary public information.
That concern matters. In a clean market, prices reflect broad information. In a dirty one, a small group can tilt the board through low-liquidity abuse, coordinated trading, or simply knowing something everyone else does not. Prediction markets can look elegant from a distance, but once the underlying event is weather, politics, sports or conflict, the temptation to game the edge gets very real.
For readers new to this corner of crypto, a prediction market is a platform where users buy and sell contracts tied to future outcomes. Polymarket says its contracts cover politics, economics, sports, weather and armed conflicts. If the outcome happens, the contract pays out. If it does not, it expires worthless. In theory, the price reflects the crowd’s estimate of the odds. In practice, it can look like a strange mix of trading terminal, sportsbook and rumor mill.
That awkward mix is exactly why regulators keep circling it. Depending on the jurisdiction and the contract type, a prediction market may be treated as gambling, a financial instrument, or something that does not fit neatly into either bucket. Regulators hate that kind of ambiguity. It is bad for paperwork and worse for enforcement.
France is not the only place taking a hard look. Spain temporarily prohibited both Polymarket and Kalshi in May. In the U.S., the argument is different but related: whether event contracts belong under the Commodity Futures Trading Commission’s authority or under state gambling laws. Supporters say the CFTC already has the right to oversee these markets. Critics say that is just sportsbook behavior wearing a derivatives costume.
The House Agriculture Committee has also been poking at the issue. Its Commodity Markets, Digital Assets, and Rural Development Subcommittee heard from legal specialists and representatives of the American Gaming Association and the Indian Gaming Association, both of which want Congress to stop platforms like Kalshi and Polymarket from offering sports event contracts. Their view is blunt: if it looks like betting and acts like betting, calling it a financial product does not magically cleanse it.
The CFTC has backed federal jurisdiction in disputes involving state regulators and released draft rules for the prediction-market industry in June. But state-level pushback has not gone away. On July 21, a Washington judge granted the state a preliminary injunction against Kalshi, finding the company’s contracts likely violated state gambling laws. Massachusetts, Michigan, Nevada and New York had also secured orders restricting Kalshi’s activities.
That is a useful reminder that “federal oversight” is not some magical force field. A preliminary injunction is not the final word, but it is a serious warning shot. If courts keep concluding that some event contracts look more like gambling than derivatives, the legal pressure will keep building.
Polymarket’s growth is one reason the spotlight has gotten brighter. Reuters reported that a person familiar with the company’s finances said annualized revenue had exceeded $1 billion. That is a run-rate estimate from an unnamed source, not audited revenue, but it still suggests the platform has moved well past the stage of being a niche crypto oddity. Big money tends to attract big scrutiny. Shocking, really.
Volume is another reason regulators are paying attention. Reuters cited Dune Analytics data showing users wagered about $19.04 billion through Polymarket and Kalshi during the recently completed soccer World Cup. That figure refers to contract activity, not a traditional sportsbook handle, but it still points to a market with real scale and plenty of incentives for abuse.
The darker side is not theoretical. Polymarket has referred nearly 100 suspicious crypto wallets to law enforcement. Bloomberg, using Polysights data, also identified about $200 million in Polymarket trades from the first half of 2026 with traits associated with potential insider activity. Much of that flagged volume involved geopolitical contracts tied to Iran and Venezuela. Bloomberg did not prove the trades were unlawful, and that distinction matters. Suspicious is not the same as criminal, even if it is enough to make regulators reach for the aspirin.
Crypto rails do not sanitize human behavior. They just make the behavior faster, cheaper and sometimes easier to spot after the fact. That is the ugly tradeoff of open markets. The same design that helps with speed and transparency can also make manipulation and privileged-information trading more attractive.
France’s move raises a larger question that Polymarket and its rivals cannot really dodge: what are prediction markets supposed to be?
To supporters, they are information markets that can surface crowd insight better than a pollster’s spreadsheet or a pundit’s hot take. To regulators, they often look like gambling with a nicer interface. To critics, they can become thin-liquidity casinos where the smartest players, or the best-connected ones, quietly eat everyone else’s lunch.
The uncomfortable answer is that they can be all three, depending on the event, the contract structure and the rules of the jurisdiction. Sports and elections usually look closest to betting. Weather can be a genuine hedging tool in some settings and a speculative toy in others. Geopolitical contracts sit somewhere between public-information markets and pure bloodsport for traders with a taste for chaos.
That is why this fight keeps spreading. France is drawing a hard line. U.S. regulators and states are drawing their own. Prediction markets are testing whether they can scale without becoming just another regulated gambling business with better branding and a crypto coat of paint.
Key questions and takeaways
-
Why did France block Polymarket?
The ANJ said the platform was offering gambling and betting services that are illegal under French law, and it flagged concerns about manipulation, losses and possible insider-style trading. -
What is Polymarket doing now?
The company says it will challenge the block through the French legal system. It has not publicly laid out the full legal strategy or a filing date. -
Why do prediction markets keep drawing regulatory heat?
Because they sit in a gray zone between gambling and derivatives. That makes them easy to use, hard to classify and very hard to police when contracts touch sports, weather, politics or conflict. -
Is the U.S. dealing with the same issue?
Yes, just under a different legal framework. The fight there is over whether the CFTC has authority over event contracts or whether state gambling laws should control them. -
Do suspicious-wallet referrals prove wrongdoing?
No. They are a red flag, not a verdict. But they do show why regulators worry that prediction markets can be abused by people with nonpublic information or a willingness to game the system.
Polymarket’s clash with France is not just a local licensing spat. It is part of a broader battle over whether prediction markets will be treated as useful information tools, tightly controlled financial products, or gambling in a fancier wrapper. The crypto crowd likes permissionless markets and price discovery. Fair enough. But if the upside is legitimacy, the downside is also unavoidable: rules, scrutiny and regulators who may decide your product is just a sportsbook with better UX.
