The 2026 FIFA World Cup is set to be the largest growth catalyst in prediction market history.

Frequently Asked Questions
How big are prediction markets in 2026?
Prediction market trading volume hit $63.5B in 2025, up from under $1B in 2023. In January 2026, combined weekly volume reached $5.23B. Polymarket recorded $7B in February 2026 alone with 688K monthly active addresses. Kalshi reported $22.88B in 2025 trading volume and revenue of $260M, a 994% year-over-year increase. The industry is now referred to as 'InfoFi' (Information Finance) and both Polymarket and Kalshi are pursuing valuations near $20B.
Can you bet on the World Cup on Polymarket?
Yes. Polymarket has launched World Cup winner markets with over $273M in volume already traded as of March 2026 \u2014 months before the tournament begins on June 11. Markets are available for outright winner, group stage outcomes, and individual match results. Kalshi, the regulated US exchange, is also expected to offer World Cup markets pending CFTC approval of additional sports event contracts.
What prediction market had the most volume for a sporting event?
Super Bowl LX in February 2026 set the record, with Kalshi alone reporting over $1B in trading volume for the event. This surpassed the previous single-event record set during the 2024 US presidential election. The World Cup, with 64 matches over 45 days across 16 venues, is projected to generate significantly higher cumulative volume due to its sustained duration and global audience.
How does the World Cup affect prediction market user growth?
Sporting events drive prediction market growth through three mechanisms: acquisition spikes from mainstream media coverage, retention from sequential game-to-game engagement, and liquidity network effects where more participants create tighter spreads and better pricing. The 2024 election grew Polymarket from roughly 50K to 300K+ monthly active users. The World Cup's 45-day duration and daily match cadence is expected to sustain engagement far longer than a single-night event.
What is the difference between Polymarket and Kalshi?
Polymarket is a crypto-native prediction market built on Polygon that uses USDC for trading and operates outside traditional US regulatory frameworks. Kalshi is a CFTC-regulated exchange that accepts USD and offers event contracts as a registered Designated Contract Market. As of January 2026, Kalshi commands approximately 66% of global prediction market trades, overtaking Polymarket primarily through sports market expansion. Polymarket remains dominant in political and crypto-native markets.
