Prediction Markets Reach Record Volumes as States Respond with New Taxes

Data indicates that monthly trading volume on prediction markets surged nearly fivefold to about $24 billion in April 2026 from under $5 billion in September 2025, and this expansion has outpaced the U.S. sports betting average of around $14 billion per month while federal CFTC oversight has enabled access in all states including those without sports betting such as California and Texas.

Understanding the Scale of Recent Growth

Trading volume on prediction markets has soared in recent months according to available figures, and observers note that this expansion stems directly from regulatory clarity provided at the federal level which opened platforms to users nationwide; the result shows consistent participation growth across regions where traditional sports betting remains restricted or unavailable, creating broader market engagement that relies on event-based contracts rather than game-specific wagers.

Those who've studied the sector know that CFTC oversight established clear guidelines for these platforms, allowing residents in California and Texas to participate without state-level sports betting legalization, and this access has driven the volume increase from September 2025 levels under $5 billion to the April 2026 figure near $24 billion while maintaining operational standards that differ from state-regulated sportsbooks.

State-Level Responses Emerge in Key Jurisdictions

Kentucky enacted a 14.25% excise tax on transaction fees in April 2026 as one direct response to the expanding activity, and this measure targets the revenue generated from each trade on prediction market platforms operating within the state; the tax applies specifically to fees collected during transactions, creating a new revenue stream for state coffers while imposing additional costs on participants and operators alike.

North Carolina has proposed a 6% tax on net trading fee revenue, and lawmakers there continue to review the framework as volumes climb, with the proposal aiming to capture a portion of the fees after operational deductions; this approach differs from Kentucky's flat excise structure yet addresses the same underlying growth trend that has accelerated since federal oversight expanded platform reach.

Both states have cited the rapid volume increase as context for their actions, while the monthly total of approximately $24 billion in April 2026 exceeds the $14 billion average seen in sports betting, prompting officials to examine how existing tax models might apply or require adjustment for this newer category of trading activity.

Comparing Volumes Across Betting Categories

Figures reveal that prediction market activity has moved ahead of sports betting averages on a monthly basis, and this shift occurs even though sports betting operates under established state frameworks in many locations; the $24 billion April total reflects participation from a wider geographic base because CFTC rules permit access everywhere, including states that have not authorized sports betting operations.

Market participants in non-sports-betting states contribute to the overall volume through contracts on elections, economic indicators, and other events, and data shows this diversity of topics sustains engagement levels that have pushed totals from under $5 billion in September 2025 to the current range near $24 billion; such patterns demonstrate how regulatory permissions at the federal level influence state-level considerations around taxation and oversight.

Broader Regulatory Context in July 2026

As of July 2026, the enacted tax in Kentucky remains in effect while North Carolina's proposal continues through legislative review, and both developments trace back to the same volume surge that federal oversight facilitated across all states; additional states have begun monitoring similar metrics, though no further actions appear in the immediate record beyond the two already documented.

The comparison to sports betting volumes holds steady at roughly $14 billion monthly on average, and this benchmark helps frame discussions in state capitals where officials evaluate how prediction market activity fits within existing gaming or financial regulatory structures; the result shows ongoing adjustments as volumes stabilize at elevated levels.

Conclusion

The documented rise in prediction market trading to about $24 billion monthly by April 2026, enabled by CFTC oversight and contrasted against sports betting averages, has led directly to specific tax measures in Kentucky and proposed legislation in North Carolina; these responses highlight how state governments track and address growth in platforms that operate under federal guidelines while reaching users in every jurisdiction.
