Polymarket has signed a multi-year agreement with Serie A USA to become the league’s official and exclusive prediction market partner in the US.

The partnership forms part of Serie A’s broader international expansion strategy and comes just a month after Polymarket signed a similar deal with LALIGA North America. 

It will see the prediction market platform integrated across the league’s US-facing media and digital channels as it looks to deepen engagement with US football fans ahead of the 2026 FIFA World Cup.

Under the agreement, Polymarket will become the exclusive US platform for Serie A prediction markets, with all markets powered by official league data supplied through NYSE-listed Genius Sports.

“The United States represents a key growth market for Serie A,” said Michele Ciccarese, Marketing and Commercial Director of Lega Serie A. 

“Our exclusive alliance with Polymarket, as Regional Partner in the USA, lets us engage a new generation of fans through a platform that embodies emerging trends. 

“It delivers an interactive, real-time product rooted in insights and participation perfectly aligned with their expectations.”

The companies stated that the use of official data is intended to strengthen “transparency, integrity and accuracy” across prediction market offerings tied to Serie A fixtures and storylines.

“The next phase of sports engagement won’t be defined by more content, but by more participation,” added Shayne Coplan, Founder and Chief Executive Officer of Polymarket. 

“Prediction markets give fans a way to actively interpret the game in real time, and partnering with Serie A brings that model to one of the world’s most followed leagues at a moment when American interest in the sport is at an all-time high.”

The deal represents another major football partnership for Polymarket as the prediction market operator continues expanding aggressively into global sports.

Polymarket said the partnership reflects growing US demand for interactive sports engagement products among younger, digitally native audiences. 

Polymarket’s rapid rise to fame

The operator has continued expanding its sports footprint in recent months, with partnerships and market offerings now spanning leagues and organisations including Major League Baseball (MLB), National Hockey League (NHL), Ultimate Fighting Championship (UFC) and Major League Soccer (MLS).

Yet this expansion has not come without its critics – particularly in Europe. Romania, Germany, Belgium, Italy, Poland, Hungary, the Netherlands, Switzerland, France, Hungary and Portugal have all prevented prediction markets from operating in their respective jurisdictions, as they believe prediction markets are a form of gambling. 

Polymarket, however, argues that it instead offers ‘events contracts’ – where users wager against each other on the outcome of an event. 

Controversy has mainly come from the company offering said ‘events contracts’ on real world events, from the mundane – such as prices on the weather – to the downright bizarre – such as prices on Jesus Christ returning – and concerning – including when the US will strike Iran.

The geopolitical markets have led to a plethora of concerns around ethics and insider trading, and White House staff have now been warned not to use insider information to put money on markets on prediction markets platforms.  

In the US, it is regulated by the Commodity Futures Trading Commission (CFTC), alongside other rapidly growing prediction markets platforms, the other major player in the space being Kalshi. 

There have been signs of even more potential expansion for the two recently, as well as the prediction markets sector in general. 

These signs have come on both sides of the Atlantic, with Gibraltar last month licensing the much-discussed ADI Predictstreet – the 2026 FIFA World Cup’s official prediction markets partner – as a B2C betting intermediary.

In a much more recent and pertinent development for Polymarket, just this week, it began offering iOS users the option download and access its US exchange, after previously only offering a waitlist and access to select customers.

The prediction markets sector has been scrutinised to no end, but its prominence is yet to wilt.

Further global normalisation of such platforms through partnerships with widely-known entities such as the Serie A is just the latest of a series of signs – however worrying – that they are here to stay.
