Polymarket has signed a multi-year shirt sponsorship with SS Lazio worth more than $22 million, making the US-based prediction market the Serie A club’s first front-of-shirt partner since its deal with Binance ended after the 2022/23 season.
Deal Structure
The agreement covers the remainder of the current 2025/26 campaign, the 2026/27 and 2027/28 seasons, and includes an option to extend through 2028/29. Polymarket’s branding debuted on Lazio’s kit during the club’s Serie A fixture against Napoli on 18 April. Additional performance-related bonuses and activation incentives sit on top of the base $22 million figure.
Beyond the shirt, Polymarket takes on the role of Lazio’s Official Fan Intelligence and Digital Insight Partner. The club becomes the first Serie A side in Polymarket’s sponsorship portfolio. The platform already holds partnerships with Major League Baseball, the NHL, UFC, MLS, and streaming service DAZN, and has a North American deal covering LaLiga.
Polymarket CMO Matthew Modabber confirmed the deal in a statement released by the club.
Lazio represents a historic institution with a forward-looking vision. We are proud to collaborate with a club that shares our approach to innovation and the enhancement of data, with the aim of building new experiences and new models in the world of sport.
Lazio president Claudio Lotito described Polymarket as “a partner that interprets the future, capable of reading and analyzing trends with innovative tools,” framing the agreement as part of the club’s international development strategy.
Regulatory Questions in Italy
Polymarket does not hold an ADM (Agenzia delle Dogane e dei Monopoli) licence, Italy’s gaming regulator. Its trading functions are inaccessible to Italian users, who can view informational pages only. The same restrictions apply in France, Switzerland, and Australia.
Italy banned sports betting advertising in 2018 and prohibits Serie A clubs from front-of-shirt agreements with gambling companies. That creates an immediate question about whether this deal is permissible under Italian law. Lazio said the agreement is “in compliance with the applicable regulatory framework,” citing a positive opinion from AGCOM, the national communications regulator, which cleared the advertising arrangement on the basis that it promotes Polymarket’s informational brand rather than its trading activity.
Whether that distinction holds with the ADM or any other Italian authority is not resolved. The club’s AGCOM consultation positions the deal as brand advertising rather than promotion of an unlicensed gambling service — a distinction that regulators across Europe have consistently resisted when applied to prediction market operators. As The iGaming EU has reported on the Danish regulatory situation, the difficulty of classifying and blocking prediction market activity without direct jurisdictional targeting is a recurring problem for European bodies.
Polymarket operates via blockchain infrastructure and stablecoin settlements rather than traditional fiat transactions — a model that has complicated regulatory classification across multiple markets. Intercontinental Exchange (ICE), the operator of the New York Stock Exchange, invested in Polymarket as part of a $2 billion round that valued the platform at $9 billion.
Commercial Context for Lazio
The deal positions Lazio in the mid-to-upper tier of Serie A shirt sponsorship revenues at approximately $9 million per season, a significant step up from the commercial vacuum left by the Binance departure. The club had been operating without a front-of-shirt partner for nearly three years.
The Italian gaming market is currently navigating a significant structural update. Italy launched a revised online gambling licensing regime in late 2025, issuing 52 active permits under the new framework. Polymarket’s position — present in the Italian market as a brand but excluded from offering licensed services — puts the Lazio deal into a regulatory grey area that the ADM has not yet publicly addressed.
The outcome of any regulatory scrutiny will have implications beyond Lazio. If Italian authorities accept the AGCOM opinion as sufficient cover, it sets a precedent for prediction market platforms to buy shirt sponsorships across Serie A without holding gaming licences. If they do not, the deal faces a challenge that the club and Polymarket have not publicly accounted for.
