Kalshi has recently achieved a significant milestone, surpassing $100 billion in total notional volume.
This achievement was propelled by major sporting events, allowing the prediction market platform to see its first-ever $1 billion volume days. Additionally, the introduction of perpetual futures has further spurred activity on the exchange.
Surpassing $100 Billion Notional Volume
The total notional volume on Kalshi, recognized as the largest prediction market operator in the United States, recently crossed the impressive mark of $100 billion. This achievement was facilitated by a series of high-profile sporting events that allowed the exchange to record its initial $1 billion turnover days.
As of last week, Kalshi’s cumulative notional volume reached approximately $102.3 billion, placing it around $9 billion ahead of its closest competitor, Polymarket. While these figures are commendable, a deeper investigation into notional volume is necessary.
Understanding Notional Volume
Notional volume refers to the overall theoretical value traded over a defined timeframe, extending beyond simple transaction counts. It accounts for market depth, indicating actual financial commitments instead of just volume,” explains Amana. “In the context of trading, notional volume reflects the dimensions of trades, encompassing both size and price. It offers a thorough insight into financial activity, highlighting the flow of money.”
This means that a prediction market’s notional volume does not directly equate to the sports betting handle, which tracks the total stakes bettors place on specific events.
The Importance of Sports in Prediction Markets
Led primarily by Kalshi, prediction market operators are striving to expand beyond the sphere of sports and reshape their identity as alternatives to traditional sportsbooks. This strategy involves focusing on institutional clients and exploring innovative use cases, with promising signs of advancement on this front.
Nevertheless, derivatives tied to sports remain crucial to platforms like Kalshi. According to a study by the Pew Research Center, sports derivatives accounted for an impressive 80% of Kalshi’s volume between July 2024 and April 2026. New data suggests that it was indeed sports that propelled the company towards its inaugural $1 billion volume days.
For instance, Kalshi recorded a notional volume of $1.22 billion on Saturday, June 13—a day marked by Game 5 of the NBA Finals and various World Cup matches. This record was then surpassed the next day, with notional turnover reaching $1.24 billion, bolstered by additional World Cup games, game six of the Stanley Cup Finals, and the UFC Freedom 250 event.
A Record-Breaking Weekend for Sports Events
Sunday proved to be one of the busiest days in 2026 for sports enthusiasts, as indicated by the substantial prediction market volume generated.
Don’t Overlook “Perps”
While distinct from event contracts, perpetual futures, colloquially known as perps, are contributing significantly to the uptick in activity on Kalshi.
The trading of cryptocurrency perps commenced on Kalshi last Wednesday, achieving over $100 million in volume during its first day—an optimistic indicator considering that Bank of America estimates these instruments produce around $90 trillion in annual trading activity globally.
“Perpetual futures are a category of derivative contracts that empower traders to speculate on asset prices—such as Bitcoin, Ethereum, and other cryptocurrencies—without the necessity of owning the underlying asset itself,” according to Coinbase. “Unlike conventional futures contracts, perpetual futures lack an expiration date, allowing traders to maintain their positions indefinitely, provided they fulfil the required margin.”
