Lazio Ends €19m Sponsorship Deal with Polymarket After Gambling Ruling

Lazio’s search for a main shirt sponsor starts all over again.

The club confirmed that its lucrative agreement with Polymarket, signed only in April 2026 and worth a reported €19m, has been terminated by mutual consent after Italian authorities ruled the platform illegal in the country.

For a club that spent last season as the only Serie A side without a primary shirt sponsor, the Polymarket deal had looked like a long-awaited commercial breakthrough. It was set to run for two seasons, with an option to extend into the 2028-29 campaign. A rare piece of stability in a volatile sponsorship market.

That stability has vanished in a matter of weeks.

Italian law draws a hard line on gambling promotion. Polymarket tried to argue it was a prediction market, a platform built on users exchanging odds with each other rather than a classic betting site. The distinction mattered: prediction markets can, in some cases, slip through regulatory gaps that bookmakers cannot.

The authorities were unconvinced.

The Customs and Monopolies Agency (ADM) ruled that Polymarket was, in essence, a betting site. Once that verdict landed and the platform lost its appeal, access to Polymarket from Italy was blocked. At that point, Lazio’s new partnership stopped being a commercial question and became a regulatory one.

A club whose shirts are broadcast weekly across the country could hardly continue to advertise a site that Italians are legally prevented from using.

Lazio moved to close the chapter, but not without securing a key concession. In their official statement, the club revealed that as part of the settlement, Polymarket will still pay the full amount due for the 2026/27 season. For the balance sheet, that matters. The sponsor disappears from the front of the shirt; the money does not.

The language from both sides remained notably cordial. Lazio spoke of “mutual cooperation,” “mutual respect,” and a “mutually agreed solution” that protects the interests of both parties in light of the “new measures” imposed by the authorities. The tone was clear: this is not a feud, it is a casualty of regulation.

There was even a door left ajar. The statement underlined that, should the regulatory framework change in the future, Lazio and Polymarket would look “favourably” on the chance to work together again.

For now, though, the reality is stark. The Aquile are back where they were not long ago: a major Serie A club with an empty space on the chest of one of Italian football’s most visible shirts, navigating one of Europe’s toughest advertising environments for anything that even resembles gambling.
