North Carolina’s 6% Prediction Market Tax and 23% OSB Rate Create Clear Arbitrage Signals
North Carolina’s new budget delivers a 6% tax on prediction market revenue paired with a 5 percentage point increase in the online sports betting tax to 23%. Governor Josh Stein signed the bill Tuesday morning. Its effective date was last Wednesday.
This marks the second state this year to tax prediction markets. The structure taxes federally regulated platforms without layering on state regulation. Enforcement questions remain open on both the North Carolina and Illinois approaches.
According to reporting by InGame some stakeholders have speculated that Kalshi helped shape the prediction market tax language. A Kalshi suit against North Carolina would test that theory the same way its Illinois filing did before the July 1 effective date there.
Tax Mechanics and Personal Deduction Changes
The bill lifts the online sports betting tax from 18% to 23%. It also updates how North Carolina taxpayers handle gambling losses on personal returns.
The text allows a deduction for wagering losses under section 165(d) of the Code to the extent those losses are not already deducted in arriving at adjusted gross income. The provision sits inside broader itemized deduction rules that remove the overall limitation under section 68.
These changes land at the same time the state carves out distinct treatment for prediction market revenue. The rate gap alone is large enough to shift commercial incentives.
Speculation on Kalshi’s Role
The prediction market language first appeared in the budget bill the day before publication. Sen. Brent Jackson confirmed that timeline. Democrats complained during debate that Republicans wrote the budget without any Democratic input.
Democratic Objections and Tribal Concerns
Several Democratic lawmakers questioned the prediction market tax during floor debate. Rep. Pricey Harrison who voted against the budget told colleagues it “seems to undermine our ability to govern and regulate sports gambling. It seems to harm tribal casinos and legal sports betting and it seems to give them some veracity in our state.”
“Sports betting companies are going to look at these frameworks and move into the prediction market,” Democratic Sen. Michael Garrett said during debate. “Why wouldn’t [they]? We’re building them the exit ourselves. … These are not small questions, and not one of them has an answer today. North Carolinians deserve to know that we saw it coming.”
The comments spotlight the competitive tension. Tribal exclusivity and regulated sportsbooks face a lower taxed adjacent product created by the same legislature that protects their positions.
The Counter View on Revenue Without Court Costs
Kurt Bardella posted that the new NC tax on prediction markets is appropriate given difference in economics between OSBs and prediction markets. He added that prediction markets can and do contribute to state revenue. Bardella called it smart of NC to pass legislation versus waste taxpayer dollars in court.
That perspective collides with the Democratic critique. One side sees efficient revenue capture. The other sees an exit ramp that undercuts the regulated market the state spent years building.
Where the Arbitrage Risk Lies
The risk sits in the split treatment. A 6% rate on prediction market revenue against 23% on sports betting revenue gives operators a structural reason to reroute volume. Garrett flagged exactly that incentive.
From the supplier side this kind of tax and regulatory mismatch is what forces platforms to maintain parallel compliance paths. In my experience across European regulated markets operators price that overhead into their models faster than lawmakers anticipate.
North Carolina’s approach adds one more data point to the fragmentation map. States are choosing different combinations of tax take and oversight intensity. Kalshi’s Illinois suit offers the first court test of where the federal line sits.
The next signal will come from whether Kalshi challenges North Carolina and how quickly sportsbook operators adjust product roadmaps. Tribal stakeholders and licensed operators now have fresh numbers to model. The arbitrage window is open.
