Kalshi Teams Up With ADI Predictstreet to Dominate World Cup Prediction Markets

Two major players in the prediction market space have joined forces. Kalshi and ADI Predictstreet have unveiled a strategic collaboration aimed at scaling prediction markets on a global level, with co-branded activations planned throughout the FIFA World Cup 2026™ knockout stage — and ambitions that stretch well beyond the tournament itself.

The partnership links Kalshi, which holds approximately 90% of the regulated US prediction market share according to Bank of America estimates, with ADI Predictstreet — the officially designated FIFA prediction market partner for the tournament. Together, the companies will launch a co-branded hub offering football prediction markets, real-time updates, and exclusive content designed for fans worldwide.

Visibility and Infrastructure at the Core

Kalshi's branding will be featured alongside ADI Predictstreet in stadium environments, television broadcasts, and digital placements as the World Cup advances into its knockout rounds. Once the tournament concludes, the collaboration is set to continue, with Kalshi actively supporting ADI Predictstreet's expansion across its international markets.

Beyond branding and fan engagement, both firms plan to explore deeper technology integrations through ADI Chain's infrastructure. The roadmap includes stablecoin deployment, Web3 product development, and on-chain settlement solutions tailored to global regulatory environments.

ADI Predictstreet CEO Dimitrios Psarrakis described the partnership as part of a broader vision to construct a worldwide ecosystem spanning sports, news, entertainment, and real-world event prediction. ADI Predictstreet became an official FIFA partner earlier this year, making history as the first-ever prediction market brand to hold that distinction at a FIFA World Cup.

Kalshi co-founder and CEO Tarek Mansour emphasized the scale of the 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."

Record-Breaking Numbers Drive the Deal Forward

The timing of this announcement is no coincidence. Kalshi has been experiencing an extraordinary performance streak. In the first two weeks of World Cup competition, the platform recorded daily trading volumes surpassing $1 billion — a milestone that underscores just how rapidly regulated prediction markets are gaining mainstream traction.

Current market data indicates that Kalshi commands approximately 62% of total prediction market trading volume globally, with rival platform Polymarket holding around 28%. These figures reflect Kalshi's growing dominance in a space that is rapidly evolving.

Kalshi has also secured a series of tournament-specific partnerships beyond the ADI Predictstreet deal. The platform has signed agreements with the Argentine Football Association, the Croatian Football Federation, podcasting duo Men in Blazers, and Croatian football icon Luka Modric.

ADI Predictstreet's Blockchain-Ready Foundation

Prediction markets have been a defining feature of World Cup media coverage since the tournament's opening day, signaling a structural shift in how fans engage with major sporting events. ADI Predictstreet operates under a Gibraltar license and has integrated Chainlink oracle infrastructure to power its settlement data. The platform is built on ADI Chain's compliance-ready blockchain, which is structured to meet regulatory standards across multiple jurisdictions.

The real test for both companies will come after the final whistle. Converting the enormous wave of World Cup interest into a sustained base of active prediction market participants is a far more complex challenge than riding tournament excitement. Crypto-linked World Cup betting has already shattered previous records — but long-term growth will depend on whether casual football fans become regular traders in the months and years ahead.
