Prediction market platform Kalshi experienced a significant surge in user growth and trading activity during the 2026 FIFA World Cup. Over the course of the tournament, Kalshi added 3 million new users, according to company data shared with CNBC. Trading volumes on the platform soared, with more than $1.2 billion traded on contracts predicting the winner of the World Cup—a record for a single market. This market is set to close on Sunday, following the final match between Spain and Argentina for the championship title [1].
Kalshi implemented several strategic marketing initiatives to capitalize on the World Cup's global appeal. The company partnered with ADI Predictstreet, the official prediction market sponsor of the World Cup, to feature co-branded advertisements in stadiums. Additionally, Kalshi collaborated with OpenAI to display contract odds in ChatGPT searches related to tournament games. High-profile advertising campaigns featured soccer personalities such as Luka Modric, José Mourinho, and the Argentina national team, culminating in a social media post by Lionel Messi. The company also broadened its reach with advertisements featuring non-soccer celebrities like Timothée Chalamet and J Balvin [1].
Kalshi CEO Tarek Mansour emphasized the importance of speed and creativity in the company's marketing strategy, noting that one advertisement featuring former soccer stars was conceived, executed, and released within 24 hours. Marketing experts highlighted Kalshi's efforts to leverage the World Cup's massive global audience and to position the platform as relevant beyond just sports fans [1].
The surge in users and trading volumes, combined with high-profile partnerships and agile marketing, underscores Kalshi's ability to capitalize on major global events to drive growth and brand awareness [1].
