Source: Kalshi's annualized revenue topped $4B in July, up from $2B+ two months earlier, and its operating expenses totaled $300M in June
World Cup wagers helped double Kalshi's revenue to a more than $4 billion annualized rate in July, from a pace of over $2 billion two months earlier, a person familiar with the matter said.
Context & Ripple Effects
Kalshi had already moved from a $600 million-to-$700 million annualized net-revenue pace in November to more than $2 billion in annualized revenue by June. Its latest reported pace extends that acceleration, with World Cup wagering supplying the immediate catalyst.
The growth arrives after Kalshi's $1 billion raise at a $22 billion valuation and reports of a prospective higher-valued round. The newly reported June expense figure gives investors a cost reference point alongside the rapid revenue run-rate growth, without establishing profitability.
First-order effects
- Kalshi can present a materially larger revenue scale in fundraising discussions, while the $300 million June operating-expense figure becomes a central measure of how efficiently it is supporting that growth.
- World Cup activity has concentrated wagering demand on Kalshi at a moment when it and Polymarket are competing for the same high-profile event markets.
Second-order effects
- Polymarket faces greater pressure to match Kalshi's liquidity and distribution around major events, as bets across the two platforms' World Cup-final markets already exceed $5.69 billion.
- Investors evaluating Kalshi's reported funding talks will focus more closely on whether event-driven revenue growth persists beyond the World Cup and how it compares with the company's operating-cost base.
Third-order effects
- If major events repeatedly drive step-changes in revenue, prediction-market competition may increasingly center on winning liquidity during cultural and sports tentpoles rather than simply expanding market catalogs.
- The contest between Kalshi and Polymarket is becoming a scale-and-regulatory-positioning race, with their reported lobbying efforts raising the stakes of which platform can translate event demand into a durable business.
The trend: Prediction markets are turning major live events into recurring liquidity tests that shape both platform scale and regulatory competition.
