Kalshi Gains 3 Million Users During World Cup
Kalshi said it acquired 3 million new users during the 2026 FIFA World Cup as trading volumes surged across prediction markets. More than $1.2 billion was traded on Kalshi’s single market asking traders to predict the World Cup winner, a record for one market. The company executed multiple brand and advertising moves during the tournament, including a stadium co-branding partnership with ADI Predictstreet, a tie-up with OpenAI to surface Kalshi odds in ChatGPT searches, and celebrity campaigns featuring Luka Modric, José Mourinho, the Argentina national team (including a Lionel Messi Instagram feature), Timothée Chalamet and J Balvin. Kalshi faces regulatory scrutiny over sports event contracts in a federal-versus-states dispute, but the company says the CFTC should regulate prediction markets. CNBC disclosed a commercial relationship with Kalshi.
Substantial user growth and record single-market trading volume highlight consumer demand for prediction markets during major sports events; partnerships with ADI Predictstreet and OpenAI increase visibility. The ongoing federal-vs-state regulatory dispute over sports contracts means potential legal and market risk for similar products.

Kalshi Prediction Markets Surge During World Cup
Manager Magazin’s Finance Forward newsletter spotlights a World Cup‑driven boom for prediction‑market platforms, led by Kalshi. Kalshi — described as the market leader — saw stakes climb to $2.9 billion in the first two weeks of the tournament, outpacing March Madness, while its valuation reportedly rose to $22 billion over the past year. CEO Tarek Mansour (30) gave an interview about a global expansion push. The piece frames an industry debate over whether large prediction markets are emerging as financial exchanges or resemble large‑scale online gambling, and notes rival Polymarket and major investors (Sequoia, Charles Schwab, KKR). The newsletter also includes unrelated fintech and payments briefings (Meta’s investment in Cred / leadership move, Wero expansion, ECB digital euro progress) and consumer payments data from the Deutsche Bundesbank.

The newsletter also notes Bank of America and Morgan Stanley beat expectations in early earnings, Broadcom and Meta expanded a partnership tied to Meta's custom AI chips, and reports that United Airlines CEO pitched a potential merger with American Airlines earlier this year.
