Three years after a federal court forced the CFTC to let it list regulated event contracts, Kalshi has quietly become what its founders always claimed it would be: the dominant US-legal prediction market exchange. 2026 has been the year that claim finally matched the data.
Daily notional volume on Kalshi’s flagship markets (FOMC rate decisions, Senate control, Super Bowl) now regularly exceeds $10 million. A year ago those same markets saw a fraction of that. The platform has added more than 400 new active contracts in the last twelve months, launched full sports coverage after a protracted regulatory review, and started reporting to tax authorities with the same rigor as a traditional commodities broker.
For a review of the current platform (fees, markets, bonus codes, and how it compares to Polymarket), see our full Kalshi review. This piece is about how it got here and where it is headed.
From regulatory experiment to scale
Kalshi’s 2023 court win against the CFTC was narrow but decisive. The commission had argued that Kalshi’s political event contracts were effectively gambling and outside the scope of the Commodity Exchange Act. The court disagreed, ruling that binary event contracts tied to defined outcomes fit comfortably within the CFTC’s existing framework for Designated Contract Markets.
The ruling did not just permit Kalshi to list election contracts. It clarified that the CFTC had authority to oversee prediction markets as a category, which accelerated everything that followed: sports-outcome contracts in 2024, economic-indicator contracts throughout 2025, and the current expansion into weather and climate derivatives.
For users, the practical consequence is simple: every contract on Kalshi has now passed regulatory review, user funds sit in segregated accounts at insured banks, and the platform files 1099s like any other US financial institution. The friction that used to define prediction markets in the US (legal ambiguity, offshore operators, crypto-only settlement) has been largely removed.
What is driving the volume surge
Three categories have accounted for most of Kalshi’s 2026 growth.
Fed markets. FOMC rate-decision contracts have become Kalshi’s single most-traded category. The platform routinely shows tighter bid-ask spreads than Fed funds futures for the next two meetings, and research desks at several banks now cite Kalshi probabilities alongside CME FedWatch.
The 2026 midterms. Senate and House control contracts, plus individual race markets for the most competitive Senate seats, have drawn both retail and institutional flow. Kalshi has cleared settlement on dozens of primary races already this cycle and is on track to do the same for the general election in November.
Sports. After years of regulatory resistance, Kalshi launched comprehensive sports contracts in late 2024. The 2025 NFL season drove daily volumes that rival major sportsbooks on marquee matchups, and the platform has since expanded into NBA, MLB, UFC, and international soccer.
The competitive landscape
Kalshi’s main competitor remains Polymarket, which still leads on market breadth and total cumulative volume. The key differentiation is geographic: Polymarket is not legally available to US residents, leaving Kalshi with a de facto monopoly on the US market for regulated prediction markets. Our Kalshi vs Polymarket comparison covers the full trade-off, but the short version in 2026 is that US traders use Kalshi and international traders use Polymarket.
PredictIt, once the default US political prediction market, has been effectively lapped. Its $850 position cap and 10% profit fee are hard to defend in an environment where Kalshi offers uncapped positions at under 2% effective fees with full CFTC protection. PredictIt remains useful for researchers because of its long historical dataset, but its role as a retail trading venue is shrinking.
Platform milestones in the past year
- April 2025: Full NFL, NBA, and MLB contracts go live after CFTC clearance.
- July 2025: Kalshi launches a public API for programmatic trading, attracting quant and institutional flow.
- September 2025: Average daily volume crosses $5 million for the first time.
- January 2026: Expansion into weather and climate event contracts, including hurricane landfall and monthly temperature markets.
- March 2026: Introduction of multi-leg contracts for policy outcomes, allowing traders to bet on combined rate-decision-plus-statement scenarios.
Where Kalshi goes next
The most-watched frontier is cross-asset hedging. A growing number of traders are using Kalshi to offset specific real-world risks: farmers hedging weather outcomes, small businesses hedging Fed rate paths, forecasters monetizing long-term views. The CFTC has indicated in public comments that it views this use case favorably, which suggests more bespoke contract categories in 2027.
The second frontier is institutional adoption. Kalshi has confirmed it is working with at least two hedge funds on prime-broker-style access, with trade reporting that integrates with existing futures infrastructure. If that comes online, Kalshi will start to look less like a retail novelty and more like a legitimate derivatives exchange alongside CME and ICE.
The main risk remains political. A change in CFTC leadership or a Congressional move to restrict event contracts would hit Kalshi hardest, given its fully regulated status. So far, bipartisan interest in consumer protection has kept prediction markets out of the crosshairs. That is unlikely to change in an election year, but traders should continue to watch the policy environment.
