Kalshi and ADI Predictstreet Join Forces for World Cup Push
Prediction market platform Kalshi has announced a strategic partnership with ADI Predictstreet, a Gibraltar-licensed prediction market that secured an official FIFA sponsorship deal in April 2026. The collaboration, announced Friday, will see both brands displayed across stadiums, television broadcasts, and online advertisements as the FIFA World Cup 2026 enters its knockout stage.
Record Trading Volumes Across the Sector
The partnership arrived the same week prediction markets posted their highest-ever weekly trading volume. According to a blog post published by Andreessen Horowitz, an investor in both Kalshi and Robinhood, weekly trading volumes across prediction markets reached $14.5 billion for the first time. The value of outstanding bets simultaneously hit $1.6 billion, a record for the third consecutive week.
Data pulled from analytics platform Artemis, which tracks platforms including Myriad (a prediction market owned by Decrypt parent company Dastan), shows Kalshi commanding 62 percent of total trading volume last week, compared to 28 percent for rival Polymarket.
Marketing Wars: Celebrities, Athletes, and Broadcast Ads
Both Kalshi and Polymarket have ramped up marketing campaigns tied to the tournament. Polymarket aired a broadcast advertisement featuring American rapper Future. Kalshi, meanwhile, launched a campaign showcasing Croatian football star Luka Modric through a partnership with the Croatia Football Federation.
DraftKings and Rothera Enter the Arena
The surge in interest has drawn additional competitors into the market. DraftKings announced in a press release on Friday that it is launching its own prediction market exchange, called DKeX. The company stated its DraftKings Predictions product is expected to grow throughout next month, citing heightened interest driven by the World Cup.
Newer entrant Rothera, an exchange that Robinhood began routing wagers to in late May, has seen explosive growth. Weekly trading volumes on Rothera jumped from $2.1 million to $805 million, according to Artemis data.
Bernstein Had Called It a Watershed Moment
Analysts at asset manager Bernstein previously forecast that the World Cup could serve as a landmark event for the prediction market sector, noting that Robinhood and Coinbase are both using the tournament to accelerate growth in their respective prediction market offerings. The record volumes posted last week appear to validate that outlook.
