Polymarket, self-described as the world’s largest prediction market, has announced a partnership with Elon Musk’s X.
The news was first announced on the official @X account on the social media platform. The post stated, “we’re joining forces with Polymarket as our official prediction market partner”.
A press release from Polymarket gave more details on the deal.
“As part of the agreement, Polymarket and 𝕏 are launching an integrated product to deliver data-driven insights and recommendations to Polymarket. Polymarket predictions will be combined with 𝕏 data to provide live insights, incorporating real-time annotations explaining market moves directly from Grok and relevant 𝕏 posts.”
Polymarket’s prediction markets will be integrated into X, allowing users to place predictions (or bets) through the platform.
Shayne Coplan, founder and CEO of Polymarket, commented, “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.”
Polymarket takes over from Kalshi
The announcement comes two weeks after prediction market site Kalshi announced a deal with Elon Musk’s xAI company, only to retract the statement hours later. It appears Musk had other ideas and is favoring Polymarket, despite the platform being geo-blocked in the US.
Polymarket was fined $1.4 million in 2022 by the Commodity Futures Trading Commission (CFTC) and ordered to deregister US users. However, an FBI investigation in 2024 suspected that the site continued to accept US customers and raided CEO Shayne Coplan’s home.
The raid was on the back of reports that the site had been accepting US user bets on the presidential election. Polymarket handled over US$3.3 billion in trading volume on the market.
Expansion into sports betting
Similar to other prediction market sites such as Kalshi and Crypto.com, Polymarket has been expanding into sports betting markets. The site has seen over $1 billion of trading on sports markets in 2025, with almost $100 million of that coming on the Super Bowl.
However, some reports suggest the reported amount of trading may be inflated. An article by Fortune last year suggested Polymarket “exhibited signs of wash trading” with some analysts suggesting as much as 33% of trades could be wash trades.
With the reported figures, Polymarket is estimated to hold 70% of the prediction markets industry, surpassing CFTC regulated platforms Kalshi and Crypto.com.
Impact of Musk-Trump fallout
With Polymarket already facing legal scrutiny in the US, the partnership with Musk’s company could lead to further restrictions placed on its operations. Trump’s nominee to lead the CFTC, Brian Quintenz, is a board member of Kalshi, and with Trump and Elon’s public fallout, the CFTC could ramp up the pressure on Polymarket.
Quintenz announced he will resign from his position at Kalshi when taking up the role at the CFTC, but the connections with the company mean he will likely favor Kalshi and try to make it easier for the platform to continue its expansion at the expense of rival Polymarket.
Musk has yet to comment on the Polymarket partnership, but has previously stated that he sees prediction markets as more valuable than polls in predicting election outcomes.
