Polymarket named as official prediction market partner for X
Collaboration with the Elon Musk-owned social media platform confirmed, despite the platform being blacklisted and inaccessible in the US

Polymarket has entered into agreement with social media giant X to become its official prediction markets partner.
The first step in the partnership has seen the pair launch an “integrated product” on Polymarket’s crypto-native platform which will tap data and insight in real time from X.
Moves in markets will also be explained by relevant posts on the platform, as well as X’s AI tool, Grok, to help inform users.
No terms of the agreement, such as its length or any finances involved, have yet been disclosed.
According to Polymarket, the initial integration will be “the first of a suite of integrations and unique experiences that Polymarket and X will jointly develop via the partnership”.
Shayne Coplan, founder and CEO of Polymarket, said: “Combining Polymarket’s accurate, unbiased and real-time prediction market probabilities with Grok’s analysis and X’s real time insights will enable us to provide contextualised, data-driven insights to millions of Polymarket users around the world instantaneously.
“We are proud to work with X as the official prediction market partner and to continue our fruitful collaboration developing an innovative suite of product integrations.
“We look forward to enhancing X and Polymarket users’ ability to make instant sense of breaking news and make informed decisions about the future as we continue to scale our platform.”
X CEO Linda Yaccarino added: “Polymarket ensures transparency through its prediction markets, and has grown into a staple source of real-time information for many X users.
“We are pleased to partner with Polymarket and look forward to bringing our data and technology to Polymarket users through a range of creative product integrations.”
The move comes weeks after fellow prediction markets platform Kalshi announced a collaboration with Elon Musk’s xAI, only to withdraw from the deal just hours later.
Algorithms used by xAI are powered by X, with Kalshi stating it was to be a “long collaboration” between the two companies.
Kalshi also boasts President Donald Trump’s son, Don Jr, as a strategic adviser. Trump and Musk had enjoyed a very close relationship up until last week, when it spectacularly crumbled in a very public showdown on X.
Musk, who had served as an adviser to Trump during and after his election campaign, criticised the president and his proposed spending bill, and his diminished involvement with the administration in a series of social media posts.
Last month, Polymarket took in $30m (£22m) worth of trades on who would be named the next Pope, with Cardinal Robert Prevost eventually winning the race and taking on the Pope Leo XIV moniker.
However, the New York-based platform is not technically legal in the US, given it is not registered with the Commodity Futures Trading Commission.
