- Kalshi’s lifetime total notional volume recently surpassed $100 billion
- With the help of big sporting events, the prediction market operator recently notched its first ever $1 billion volume days
- “Perps” serving as another driver of activity on the exchange
Total notional volume on Kalshi, the largest US prediction market operator, topped $100 billion as the exchange recently experienced its $1 billion days in turnover terms, assisted by some high-level sporting events.
Last week, Kalshi’s lifetime notional volume soared past $100 billion as the yes/no exchange notched its first $1 billion days with the help of the NBA and Stanley Cup Finals and the start of the World Cup. It’s the latest of sign of soaring turnover on yes/no exchanges. By some estimates, Kalshi’s all-time notional volume stood at $102.3 billion entering this week, or about $9 billion ahead of rival Polymarket. Those are impressive numbers, but some exploration of notional volume is warranted.
Notional volume represents the total theoretical value traded over a certain period, exceeding mere transaction counts. It summarizes market depth, reflecting actual capital commitments rather than sheer activity,” according to Amana. “In trading, notional volume takes account of the size and price of trades. It provides an in-depth scope of financial engagement, revealing the weight of money in motion.”
Said another way, a prediction market’s notional volume isn’t a clean comparison to sports wagering handle, which measures the total amount bettors put down on a specific event.
Sports Still Critical to Prediction Markets
In an effort largely led by Kalshi, prediction market operators are attempting to diversify beyond sports and dispel the notion that they are merely alternatives to old guard sportsbooks. That includes increased attention on institutional clients and use cases and there is evidence of progress on that front.
Still, sports derivatives are vital to companies such as Kalshi. A study conducted by the Pew Research Center notes that from July 2024 through April 2026, sports derivatives drove 80% of volume on Kalshi. Fresh data confirm it was likely sports contributing to the company’s first $1 billion volume days.
Notional volume on Kalshi reached $1.22 billion on Saturday, June 13 — a day featuring Game 5 of the NBA Finals and several World Cup matches. That record was topped the following day when Kalshi’s notional turnover hit $1.24 billion, assisted by more World Cup games, game six of the Stanley Cup Finals and the UFC Freedom 250 event.
Sunday was one of the most packed days of 2026 in terms of sporting events and prediction market volume confirmed as much.
Don’t Forget “Perps”
Though a distinct asset class from event contracts, perpetual futures, or “perps,” are another source of rising activity on Kalshi.
Cryptocurrency perps started trading on Kalshi last Wednesday and volume exceeded $100 million in the first 24 hours, a potentially encouraging sign when considering that Bank of America estimates perps generate $90 trillion in annual trading activity on a global basis.
“Perpetual futures are a type of derivative contract that enables traders to speculate on the price of an asset—like Bitcoin, Ethereum, or other cryptocurrencies—without needing to buy or own the underlying asset itself,” according to Coinbase. “Unlike traditional futures contracts, perpetual futures don’t have an expiration date, meaning traders can hold their positions indefinitely, as long as they maintain the required margin.”
