France blocks Polymarket but Robinhood's Nice shirt stays on

The ANJ ordered French internet service providers to block Polymarket's website in July. The grounds were straightforward: the platform promotes an unauthorized gambling offer, and under French law, advertising such a site by any means is a criminal offense. The order was clear, the enforcement was public, and the precedent was set.

Then L'Équipe reported that the same regulator is now examining Robinhood's front-of-shirt deal with OGC Nice — a multi-year partnership announced in July 2025 that places the Robinhood name across the men's and women's first teams, training kits, stadium signage, and club digital channels. The ANJ has not published an enforcement notice naming either Robinhood or the club. No formal action has been identified.

That gap is the story.

The ANJ's stated position since February is that prediction-market platforms are unauthorized gambling operations in France. Robinhood's event contracts are restricted to US residents, which means the platform itself is not serving French bettors. What's being examined is whether the corporate logo on the shirt constitutes promotion of an unauthorized product — a different question, and a harder one to answer cleanly.

I have seen this kind of enforcement ambiguity in other cross-border financial product cases, and the regulator's problem is always the same: the product is geofenced, but the brand is everywhere. You cannot block a jersey. The legal theory that a sponsorship by a parent company promotes a subsidiary's locally-prohibited service has not been tested in any jurisdiction I am aware of, and the ANJ has not publicly explained the standard it is applying to this one.

Nine European gambling regulators issued a coordinated warning to sports organizations this year, urging them to verify the legal status of prediction-market operators before signing commercial deals. Nice signed its deal eleven months before that warning. That timing does not insulate the club from current scrutiny, but it is material context for any enforcement argument built on the club's duty of care.

What the ANJ does next is genuinely open. It can distinguish between Robinhood the trading platform — which it has not blocked — and Robinhood the prediction-market operator, and conclude the shirt is advertising the former. It can decide that the brand is indivisible and move toward a formal notice. It can sit with the ambiguity while watching what other European authorities do. The Dutch regulator blocked Polymarket in February over licensing. No European authority has yet moved against a sponsorship arrangement on these grounds.

The reporting says this is primarily a problem for Robinhood's European expansion. I think that framing understates what is at stake for the sport. If the ANJ establishes that a shirt deal with a US prediction-market operator constitutes illegal advertising under French law, every European football club that has signed or is considering signing with a prediction-market brand is looking at the same exposure. That is a structural change to a sponsorship market that has been moving toward these operators with some speed.
