Why State Regulation Breaks the Prediction Market Exchange Model

The courts are cut up on one among the most consequential questions in prediction markets: whether or not states have the proper to manage exchanges like Kalshi that supply sports activities occasion contracts below a federal CFTC license. What’s getting misplaced is the extra basic difficulty that state playing frameworks weren’t constructed for exchanges in any respect. Alex Kane, CEO of Sporttrade and the solely founder to have constructed a state-regulated sports activities prediction market alternate at scale, has quantified it: To function throughout all 38 states with authorized sports activities betting, Kane says, would value greater than $100 million upfront, $50 million or extra yearly in licensing and market entry prices, and the addition of 100-200 full-time employees “to take care of compliance with 38 totally different technical/data safety audits, 38 totally different testing certifications, 38 totally different monetary audits, and 38 totally different units of guidelines and reporting necessities.”

Those prices replicate one thing extra basic, Kane says: “States are unable to manage exchanges. They by no means contemplated that mannequin.”

Peter Hammon, an advisor and lawyer in the on-line gaming/prediction markets business, has helped construct the regulatory structure for 2 state-regulated sports activities betting exchanges, Smarkets and Sporttrade. His recommendation to anybody contemplating the identical path: “I might not advise pursuing that enterprise mannequin below state regulation anymore,” he advised DeFi Rate.

Kane and Hammon aren’t describing a regulatory headache, however a structural incompatibility between state playing regulation and the alternate mannequin, compounded by equally problematic tax frameworks. As greater than a dozen states transfer to limit or tax federally licensed exchanges, the Third Circuit ruled April 6 that New Jersey can’t implement its playing legal guidelines in opposition to Kalshi, the strongest judicial endorsement but of a single federal framework. The Ninth Circuit, nevertheless, allowed Nevada to do the reverse. The cut up might take years to resolve.

In the meantime, the sensible constraints are already clear. As Hammon recently put it, there was “not almost sufficient dialogue” about the sensible impossibility of operating a state-regulated prediction market in the US. That begins with how exchanges truly work.

What makes an alternate totally different

A standard sportsbook units costs and earnings while you lose. An alternate, the mannequin utilized by Kalshi and Sporttrade, is a market the place contributors put up bids and provides in opposition to one another. The platform takes a small fee on matched trades and is detached to the final result. Liquidity is dependent upon market makers: skilled counterparties who repeatedly quote costs on each side. With no market makers, there’s no liquidity. And with no liquidity, there’s no alternate. But state gaming laws expressly prohibit key alternate infrastructure.

State playing regulation was written to manage bookmakers, not exchanges. When Kane constructed Sporttrade below state guidelines, the end result was 5 separate exchanges throughout New Jersey, Colorado, Arizona, Iowa, and Virginia — every with its personal order e book, matching engine, and licensed liquidity suppliers, every legally unable to match a buyer in a single state in opposition to a buyer in one other.

When federally-licensed rivals launched nationally with unified liquidity swimming pools, Kane wrote to the CFTC in April 2025 citing “irreparable hurt” and pivoted towards federal designated contract market standing. “We determined to view the disruption as a constructive for patrons, and thus a constructive for our imaginative and prescient,” he advised DeFi Rate.

The pivot is turning into an business sample. Kane doesn’t fault the regulators, however he factors to a structural limitation: “I respect the state-regulated system for what it’s, and I respect the regulators personally. I feel the regulated merchandise work (albeit not for everybody), and so they create tax income,” says Kane. “They by no means contemplated that mannequin, as evidenced by the lack of even defining the core components of an alternate ecosystem (market makers, matching engine, orderbook, brokers, and so forth).”

Hammon sees the identical shift taking part in out throughout the business: “None of those prices are at present imposed on prediction markets — which is why you see so many sportsbooks and exchanges making the leap from state regulation to CFTC regulation.”

The Phantom tax drawback: Being taxed on cash you by no means made

How states select to tax prediction market exchanges, in the event that they’re permitted to take action in any respect, is a completely untested query. And the regimes now advancing by state legislatures recommend that a few of them would make working untenable. The structural cause comes right down to how exchanges earn income versus how states have historically measured it in the gaming business.

In the UK, the Gambling Commission taxes betting exchanges on their fee income, the maker/taker fees the platform truly earns. In the US, state gambling commissions tax exchanges on complete buyer losses (Gross Gaming Revenue). On a betting alternate, most of that cash flows on to the market maker on the different aspect of the commerce. The platform solely retains the fee.

“It’s an essential distinction as a result of most of the income from buyer losses accrues to market makers, so exchanges wind up getting taxed on phantom income,” Hammon defined.

Iowa’s proposed SF 2470, which handed the Senate 45-1 and prompted Kalshi to sue the state earlier than it even cleared, is the starkest instance of what an unworkable tax regime seems to be like. It features a 20% GGR-adjacent levy plus a 20% excise on each single occasion contract. Kentucky’s HB 757, at present on the governor’s desk, takes a extra principled method by taxing transaction charges quite than buyer losses, which is structurally nearer to the UK mannequin. It’s a significant enchancment on Problem One. But with eleven states now contemplating their very own frameworks, it’s doable that different states comply with Iowa’s method.

Hammon says the Iowa tax provision “has no critical possibilities of ever being enforced” including that, “The CFTC would instantly sue if Iowa truly tried to gather charges from prediction markets regulated by the CFTC. As a sensible matter, no prediction market goes handy the Iowa Racing and Gaming Commission a test for $20 million.”

The $20 million determine additionally illustrates the structural absurdity of making use of state licensing economics to a federally-licensed business: “Iowa’s $20 million upfront license price is a Don Quixote proposal,” Hammon explains. “If expanded to different states at the identical price, that will equal $2 billion {dollars} per prediction market operator in Year 1. Iowa is 1% of the U.S. inhabitants.”

Kane calls state GGR-based proposals “utterly unworkable” primarily based on underlying fee economics: “The long-term fee per contract traded on prediction markets might be 0.1% to 0.3%.” Taxed on GGR quite than precise fee income, these margins face a tax invoice calculated at multiples of what the platform earned from every commerce.

Why institutional liquidity can’t enter state-regulated exchanges

The UK permits company entities to market make on betting exchanges with out a playing license. However, US states require market makers to carry the identical licenses as on line casino gear distributors, which require six-to-seven figures per state, years to acquire, with exhaustive monetary disclosure of the C-suite and buyers.

Hammon particulars the workaround that emerged: “States don’t enable for entities to wager, so at Sporttrade, we’ve needed to work with the states to create an idea that market makers are gaming ‘suppliers’ or ‘distributors’ to Sporttrade quite than energetic contributors. It’s a inventive workaround, but it surely exposes market makers to an intensive licensing investigation that prices six figures and takes months or years to finish.”

“As you may think about, that has scared off most wall avenue corporations that in any other case would like to take part,” says Hammon. 

Kane identifies two foundational necessities that state regulation prohibits outright: finish customers buying and selling electronically, and entities collaborating as clients. On federally-regulated exchanges, institutional market makers, that are organizations, not people, are the major supply of liquidity. But state regulation doesn’t acknowledge them as eligible contributors.

Kane famous that whereas Sporttrade does have two licensed service suppliers that provide liquidity to the alternate, “such a licensing course of is so onerous that it has eradicated the 99% of market makers that take part on venues federally, however can’t on Sporttrade.”

“Many of such contributors have inquired about becoming a member of Sporttrade, however went chilly once they discovered about the licensing course of,” Kane advised DeFi Rate.

Every state is its personal island

The Wire Act bars sports activities wagering transactions from crossing state traces, forcing every state’s order e book to function in isolation.

“Combined with state legal guidelines that require sports activities betting servers to exist in every state, these guidelines imply an organization like Sporttrade is obligated to arrange a special server in every state,” Hammon advised DeFi Rate. “Each server should have its personal matching engine, the tech that matches bettors in opposition to different bettors or in opposition to market makers.”

Hammon defined the dire impact of Wire Act limitations on fundamental features of the alternate mannequin: “From a tech standpoint, this implies…artificially capping liquidity, and dropping the pricing, liquidity, and different advantages that draw clients to a betting alternate/prediction market in the first place.”

Then there’s the difficulty of getting to adjust to 38 totally different regulatory regimes for licensing, operation, reporting and extra, a requirement that Kane calls “utterly unworkable for any start-up.”

“It’s why there at the moment are zero ‘startups’ that function wherever in the regulated market, outdoors of Sporttrade.”

Why a license nonetheless wouldn’t be sufficient

Hammon’s three structural issues are about misalignment between how exchanges work and what state sports activities betting laws enable. Anthony Busacca, CFO of Sporttrade, makes a more fundamental point, particularly that the laws don’t simply make the alternate mannequin troublesome, however prohibit it outright.

“States don’t enable entities to wager, don’t enable algorithmic/bot buying and selling, most don’t enable gamers to supply their very own value, State operators are allowed to restrict/ban winners, the record goes on. So it’s not as simple as saying Kalshi can simply get a license in every State, as the laws/statutes don’t enable for the mannequin. So getting licensed would nonetheless imply they couldn’t function a real alternate mannequin at the state degree.”

Those prohibitions goal key pillars of buying and selling exchanges. We already coated the difficulty of “no entity betting,” which undercuts the market making engine. No algorithmic buying and selling means institutional market makers can’t function their core infrastructure, and with out steady high-frequency quoting, spreads widen and liquidity collapses. No restrict orders, “most don’t enable gamers to supply their very own value,” could possibly be the most detrimental prohibition of all as restrict orders are the basis of the conventional order e book and an integral a part of value discovery. And the capacity to ban successful gamers, customary follow for state-licensed sportsbooks, straight codifies the bookmaker mannequin into regulation and contradicts the alternate’s core promise of equity to all contributors.

Winning the preemption argument clears state regulation out of the approach and replaces it with a framework that, as Kane found, already has the proper foundations for exchanges. When Sporttrade started its DCM software, he says, “it grew to become instantly clear that the CFTC already had guidelines and insurance policies for a way contributors might join, how entities can take part, how intermediation would work — all issues which are conditions to successfully regulating exchanges.”

The CFTC’s pending rulemaking addresses a narrower set of open questions like which occasion contracts are permissible and what restrictions apply to sports-related contracts particularly quite than the alternate mechanics that federal regulation already covers.

Why that is coming to a head now

The Third Circuit’s April 6 ruling in KalshiEX LLC v. Flaherty, a 2-1 determination, held that Kalshi’s sports-related occasion contracts are swaps traded on a CFTC-licensed Designated Contract Market, and that the Commodity Exchange Act’s grant of unique federal jurisdiction preempts New Jersey’s playing legal guidelines. The courtroom sided with Kalshi’s “slim framing”: New Jersey wasn’t regulating playing broadly, it was impermissibly regulating buying and selling on a federally designated market.

It is the strongest judicial sign but that prediction markets belong below a single federal framework. It can also be not the last phrase. New Jersey can search en banc rehearing. More critically, the Ninth Circuit went the different approach on Nevada final month, clearing that state to implement its playing legal guidelines in opposition to prediction markets. The circuit cut up is dwell. The CFTC sued Arizona, Connecticut, and Illinois on April 2 in a parallel effort to lock in federal preemption. A wave of House and Senate proposals with some geared toward banning sports activities occasion contracts on CFTC-regulated platforms, provides a congressional dimension that the courts alone can’t resolve.

Hammon thinks it is going to be 1-2 years earlier than the difficulty makes it to the Supreme Court, and that “Status quo holds till then, minus a couple of states which will get picked off like Nevada.”

While he thinks Congressional motion continues to be unlikely, he additionally says “Kalshi and Polymarket PR campaigns are so aggressive that it’s truly making a threat there.”

What comes subsequent

The structural issues Hammon and Kane describe don’t anticipate the courts to settle the preemption query. If states win, the alternate mannequin faces a statutory panorama that prohibits its core mechanics fully: the phantom tax regimes, the market-maker restrictions, the Wire Act fragmentation, and the outright statutory prohibitions that Busacca recognized all apply concurrently. The mannequin doesn’t simply develop into troublesome however not possible, and even doubtlessly unlawful.

If states lose and preemption holds, the image modifications considerably. The CFTC framework already handles the alternate infrastructure, protecting entity participation, algo buying and selling, order books, and intermediation. The remaining open query is the upcoming rulemaking on clear contract guidelines and restrictions. Kentucky’s transaction-fee method factors towards a workable tax mannequin if states retain any taxation rights in any respect, however Iowa’s method factors in the wrong way. The UK reveals what occurs while you get the construction proper after which tax it to loss of life.

For Hammon, who has now navigated each paths, the path is evident:

“I’ve now helped launch two totally different state-regulated sports activities betting exchanges — Smarkets and Sporttrade. I might not advise pursuing that enterprise mannequin below state regulation anymore. If you might have the tech able to go, do no matter you may to accumulate a CFTC DCM as quickly as doable, or look to associate with an current DCM that will not have sports activities wagering alternate expertise in place.”

In follow, the business isn’t ready for the courts. It’s already selecting the mannequin that works.
