Kalshi Teams Up With ADI Predictstreet to Take Prediction Markets to the Global Stage

In a move set to reshape the prediction market landscape, Kalshi and ADI Predictstreet have formalized a strategic partnership aimed at expanding regulated event trading across international markets. The collaboration will debut prominently during the FIFA World Cup 2026™ knockout stage, with co-branded placements spanning stadium environments, television broadcasts, and digital platforms.

The timing is no coincidence. Kalshi currently commands approximately 90% of the regulated US prediction market share, according to Bank of America estimates, making it the dominant force in the sector. ADI Predictstreet, meanwhile, holds the distinction of being the tournament's official FIFA prediction market partner — a first in World Cup history, as no prediction market category had ever been recognized at this level before.

At the center of the partnership is a jointly developed co-branded hub that will offer football prediction markets, real-time match updates, and exclusive fan-oriented content. The initiative is designed to draw casual football fans into the prediction market ecosystem while giving both brands significant exposure during one of the most-watched sporting events on the planet.

Kalshi's branding will appear alongside ADI Predictstreet across all major promotional channels as the tournament progresses into its knockout rounds. Once the final whistle blows, the partnership doesn't stop there. Kalshi has committed to supporting ADI Predictstreet's expansion efforts across its existing international footprint, with both firms eyeing infrastructure integrations built on ADI Chain's blockchain technology. The roadmap includes stablecoins, Web3-native products, and on-chain settlement mechanisms designed for global market compliance.

ADI Predictstreet CEO Dimitrios Psarrakis described the ambition as nothing less than building a global ecosystem that reaches across sports, news, entertainment, and real-world events. The company operates under a Gibraltar license and has already integrated Chainlink oracle infrastructure for settlement data, with ADI Chain's compliance-ready blockchain underpinning the entire platform.

Kalshi co-founder and CEO Tarek Mansour framed the deal in terms of scale and opportunity: "The World Cup™ is the largest stage for any brand. We see this as a massive opportunity to increase global awareness and fan engagement. We're excited to partner with ADI PredictStreet to bring more fans into the prediction market action."

The numbers backing this partnership are striking. In just the first two weeks of World Cup play, Kalshi recorded daily trading volumes exceeding $1 billion — a record-breaking pace that underscores how deeply prediction markets have penetrated mainstream sports culture. Kalshi currently accounts for roughly 62% of total prediction market trading volume globally, with Polymarket trailing at approximately 28%, based on market-tracking data.

Kalshi's World Cup push extends beyond the ADI Predictstreet deal. The company has also signed partnerships with the Argentine Football Association, the Croatian Football Federation, podcasting duo Men in Blazers, and Croatian football icon Luka Modric — a roster of collaborations that signals an aggressive strategy to cement its brand among global football audiences.

Prediction markets dominated coverage from the tournament's very first day, reflecting a broader surge in regulated event-based trading. Yet the real test lies ahead. Converting World Cup excitement into sustained, long-term engagement from football fans remains a significant challenge. Whether Kalshi and ADI Predictstreet can maintain their momentum well beyond the tournament's closing ceremony will ultimately define the true value of this partnership.
