Kalshi adds 3 million new users as prediction market capitalizes on the World Cup
The 2026 FIFA World Cup has transformed the trajectory of prediction markets. Kalshi reports the addition of 3 million new users during the tournament, marking a significant expansion for the platform. Trading volume on World Cup-specific contracts reached $1.2 billion, setting a record for a single market on the site.
To capture this audience, the company initiated a strategy centered on high-profile partnerships and rapid media production. Advertisements featured soccer figures including Luka Modric and José Mourinho, alongside a notable social media post from Lionel Messi. Beyond soccer, the firm expanded its reach by partnering with OpenAI to display contract odds directly in ChatGPT search results and collaborating with cultural figures such as actor Timothee Chalamet and singer J Balvin.
This growth strategy relies on the global reach of the World Cup, which experts note possesses an unmatched addressable market. The company prioritized speed in its creative output, with CEO Tarek Mansour citing a 24-hour turnaround for a recent campaign featuring former professional players. Despite this success, the firm faces ongoing regulatory tension. State governments continue to argue that these sports contracts function as sports betting, an area historically controlled by state authorities rather than the federal Commodity Futures Trading Commission. Kalshi maintains that it falls under federal oversight and characterizes industry opposition as pressure from traditional gambling incumbents.
Looking forward, the challenge for the platform involves converting these tournament-driven users into long-term, recurring traders. While historical volume data shows a decline in activity once major events conclude, the company expresses confidence in future market activity. The strategy hinges on the assumption that global events will consistently generate new opportunities for prediction contracts. As the World Cup final approaches, the firm aims to prove that its market utility extends well beyond major sports competitions.
