Prediction Markets Reach Record Volumes as States Introduce New Tax Measures

Trading volume on prediction markets reached approximately $24 billion in April 2026, marking a near fivefold increase from under $5 billion recorded in September 2025, and this expansion occurred under federal CFTC oversight that granted nationwide access including states without sports betting legalization such as California and Texas.

Observers note that the monthly average for U.S. sports betting stands around $14 billion, which places the prediction market figures ahead during this period, and data shows the surge stems directly from regulatory clarity that allowed platforms to operate across all jurisdictions.

Regulatory Framework Enables Broader Access

Federal oversight by the CFTC created conditions for prediction markets to expand without state-by-state restrictions that often limit sports betting, and this framework permitted users in non-gambling states to participate in event contracts on topics ranging from elections to economic indicators.

Those who've tracked the sector point out that previous barriers kept volumes lower until the uniform federal approach took hold, and figures reveal steady month-over-month growth leading into the April peak.

State Governments Begin Tax Responses

Kentucky enacted a 14.25% excise tax on transaction fees in April 2026, targeting the revenue streams generated by prediction market activity within its borders, while North Carolina advanced a proposal for a 6% tax applied to net trading fee revenue as lawmakers addressed the sector's rapid expansion.

These measures emerged after volumes crossed previous thresholds, and reports indicate other states are monitoring similar legislative paths as trading activity continues at elevated levels into the summer months of 2026.

Trading volume on prediction markets has soared in recent months according to available statistics, and this growth trajectory prompted the initial tax actions in Kentucky and North Carolina as officials sought to capture portions of the new economic activity.

Comparison With Established Betting Markets

The $24 billion monthly figure for prediction markets exceeded the typical $14 billion average seen in U.S. sports betting during the same timeframe, and this outperformance occurred even though sports betting operates under a more established regulatory patchwork in many states.

Analysts tracking both sectors note that prediction markets benefited from uniform access rules that removed geographic hurdles, whereas sports betting handles vary significantly by state legalization status and tax structures already in place.

Timeline of Volume Growth and Policy Shifts

Volumes remained below $5 billion as recently as September 2025 before climbing sharply through early 2026, and the April milestone coincided with the Kentucky tax enactment while North Carolina's proposal followed shortly afterward.

By July 2026, industry observers continue to reference the April data as evidence of sustained interest, and state legislative sessions have incorporated discussions around similar revenue measures in additional jurisdictions.

Market Participation Across Jurisdictions

Access in states such as California and Texas expanded the potential user base beyond traditional sports betting regions, and this nationwide availability contributed to the overall volume increase without requiring individual state approvals for each platform.

Participants engaged through CFTC-regulated exchanges on contracts tied to verifiable outcomes, and transaction data shows higher activity levels in previously restricted areas compared to pre-oversight periods.

Conclusion

The sequence of volume growth followed by state tax responses in Kentucky and North Carolina illustrates the evolving regulatory landscape around prediction markets as of mid-2026, and the CFTC framework remains central to the operational model that drove the increase from under $5 billion to $24 billion monthly.

Additional states continue to evaluate their approaches based on these developments, and the comparison to sports betting volumes provides context for the scale of activity now occurring across prediction platforms.
