Kalsi has entered into a strategic branding and product partnership with ADI Predictstreet, the official prediction market partner for the 2026 FIFA World Cup.
From the knockout stage, the Kalshi brand will appear alongside ADI Predictstreet across stadium, TV and online advertising inventory associated with the tournament.
Kalsi will also support the long-term expansion of the markets available through ADI Predictstreet’s platform, extending the partnership beyond the World Cup.
The deal allows Carsi to increase exposure at the world’s biggest soccer event without making the company a direct official partner of FIFA. ADI Predictstreet maintains the official prediction market designation.
This partnership comes as World Cup activity drives record engagement across prediction market platforms.
Last week, daily trading volume exceeded $1 billion, Kalsi said. The company has also signed tournament-specific partnerships with the Argentine Football Association, the Croatian Football Federation, Luka Modric and the Men in Blazers.
Calsi controls about 89% of the U.S. prediction market volume, significantly outperforming competing regulated platforms, according to Bank of America estimates.
ADI Predictstreet CEO Dimitrios Psarrakis said the partnership combines Karsi’s reach with ADI Chain’s infrastructure, allowing them to introduce prediction markets to a broader global audience.
Karshi CEO Tarek Mansour said the World Cup is a huge opportunity to expand the platform’s awareness and increase fan engagement.
FIFA appointed ADI Predictstreet as its first official partner in the prediction markets category in April. The company launched its platform ahead of the tournament and operates it under a Gibraltar license.
The platform initially focused on the soccer market, but plans to expand to news, technology, entertainment, culture, and other real-world events.
The partnership comes as the expanded 48-team World Cup drives record activity across betting and prediction platforms. The tournament includes 104 matches in Canada, Mexico, and the United States.
