Crypto.com, Robinhood Take Prediction Markets to SCOTUS

Quick answer: Crypto.com and Robinhood have both asked the U.S. Supreme Court to settle a fight that’s been simmering for over a year — does the CFTC alone get to regulate prediction markets, or can individual states shut them down under local gambling law? Crypto.com’s North American Derivatives Exchange filed its petition on September 11, 2026, and Robinhood followed within days with a separate one. The two companies actually disagree on tactics: Crypto.com wants the Court to rule now, while Robinhood is asking the justices to hold off until the CFTC finishes its own rulemaking. Either way, the outcome will decide whether platforms like Kalshi, Polymarket, and Crypto.com’s own prediction markets operate as federally licensed derivatives venues nationwide, or get carved up state by state the way online sports betting was a decade ago. For crypto investors, this isn’t a side story — prediction markets have become one of the fastest-growing on-ramps into digital assets, and the legal ground they stand on is still being poured.

What Crypto.com and Robinhood Actually Asked the Court to Do

Let’s start with what happened, because the headlines have blurred two separate filings into one story.

On September 11, 2026, Crypto.com’s derivatives arm petitioned the Supreme Court to review a case testing whether sports-related event contracts count as “swaps” under the Commodity Exchange Act. If they do, the Commodity Futures Trading Commission has exclusive federal jurisdiction, and state gaming boards have no say. Crypto.com wants the Court to take the case up directly and settle it.

Robinhood filed its own petition shortly after, tied to a related dispute. But Robinhood’s ask is different in one important way: it wants the justices to pause and wait for the CFTC to finish a rulemaking process before weighing in. That’s not a small distinction. A company confident the law is already on its side usually wants a ruling fast. Asking the Court to wait suggests Robinhood would rather have a friendlier regulatory rule already on the books before a legal precedent gets locked in.

Both companies are leaning on the same core argument: the Commodity Exchange Act defines a swap broadly enough — any contract tied to “the occurrence, nonoccurrence, or extent of an occurrence of an event” — that sports and event contracts should fall under it. If that’s right, federal law preempts the patchwork of state gambling statutes entirely.

The Circuit Split That Forced This Into the Open

Cases don’t usually reach the Supreme Court unless lower courts disagree, and that’s exactly the situation here.

The Ninth Circuit, ruling on a Nevada case, found that sports event contracts do not qualify as swaps and rejected the federal preemption argument outright. That ruling effectively told Nevada it could enforce its own gambling law against prediction market operators.

Meanwhile, the Third Circuit is handling a related case involving Kalshi, where New Jersey has pushed the opposite position — that state gambling authority should govern, not federal derivatives law. The CFTC itself weighed in on Kalshi’s side, disputing the idea that its own regulatory framework leaves room for state override.

Editor’s Update (Sept 23, 2026): The Third Circuit actually ruled against New Jersey, affirming a preliminary injunction in Kalshi’s favor. That loss is what pushed New Jersey to file its own Supreme Court petition on September 2, 2026, asking the justices to review that ruling — roughly a week before Crypto.com’s filing and about two weeks before Robinhood’s. That means there are now at least three separate cert petitions asking the Court to resolve this same circuit split, from parties on both sides of the argument. A stack of petitions covering the identical legal question generally raises the odds the Court agrees to hear at least one of them, which strengthens the case that this reaches oral arguments rather than fizzling out on the cert docket.

Two federal appeals courts, two different answers to the same legal question. That’s precisely the kind of split the Supreme Court exists to resolve, which is why legal analysts think there’s a real chance the justices take one or both cases — with oral arguments possible by late 2026 or into 2027 if certiorari is granted.

Nevada Already Forced Kalshi to Pull Back

This isn’t hypothetical for the industry. Nevada’s regulators already used their state-level win to force Kalshi to shut down its offerings within the state. Connecticut went further, issuing cease-and-desist orders against multiple prediction market platforms. Underdog, another operator, responded by countersuing to challenge the state’s authority outright.

In other words, while the legal theory gets argued in briefs, the practical effect is already showing up on the ground: platforms turning off access state by state, similar to how online poker and daily fantasy sports had to fight jurisdiction-by-jurisdiction battles a decade ago before federal or state frameworks settled down.

How Prediction Markets Got Big Enough to Matter

None of this would be worth a Supreme Court fight if prediction markets were still a niche curiosity. They aren’t anymore.

Monthly trading volume across the sector climbed from roughly $5 billion to north of $24 billion over a seven-month stretch, with Kalshi alone pushing past $8.6 billion in a single month earlier in 2026, according to data tracked by industry outlets. That kind of growth curve is what turns a legal gray area into a legal emergency — regulators and courts move slowly until the dollar figures force their hand.

Part of that growth traces directly back to crypto adoption. Stablecoin settlement made it trivially easy to fund an account and cash out without touching a bank wire, and blockchain-native platforms like Polymarket removed the need for a traditional brokerage relationship entirely. A trader in a state where sports betting is illegal could still, in practice, access a prediction market functionally similar to a sportsbook — which is exactly the tension driving Nevada’s and Connecticut’s enforcement pushes.

Why This Case Matters to Crypto, Not Just Sports Betting

It would be easy to read this as a gambling-law story with no real bearing on Bitcoin or altcoins. That would be a mistake, and here’s why.

Prediction markets today are deeply intertwined with crypto infrastructure. Polymarket, the largest decentralized prediction platform, settles trades in USDC and runs on blockchain rails rather than a traditional clearinghouse ledger. It spent 2025 and much of 2026 working to reopen to U.S. traders the legitimate way — acquiring the CFTC-licensed exchange and clearinghouse QCEX for a reported $112 million specifically so it could operate onshore under federal oversight instead of offshore in a legal gray zone. Kalshi, while centralized, also leans on stablecoin rails for a meaningful share of its trading activity. And Crypto.com is, first and foremost, a crypto exchange that’s expanding into prediction markets as a new product line, not the other way around.

That means the outcome of this Supreme Court fight will directly shape how a blockchain-native financial product gets treated in the United States. A ruling that federal law preempts state gambling statutes would give platforms like Polymarket a single, nationwide compliance target — register with and answer to the CFTC, full stop. A ruling the other way keeps the current mess: fifty different state gambling regimes, each capable of shutting down access on its own timeline, regardless of what a federal regulator says.

For an industry still trying to shake the “unregulated Wild West” label, regulatory fragmentation is its own kind of risk. Investors in crypto-adjacent companies, or in tokens tied to prediction market infrastructure, are effectively exposed to whichever way this legal coin lands.

The Bigger Pattern: Crypto Keeps Ending Up in Federal Preemption Fights

If this sounds familiar, it should. Crypto regulation in the U.S. keeps circling back to the same underlying question — does a single federal framework govern digital-asset-adjacent products, or does a fragmented state-by-state approach win out? We’ve tracked that exact tension play out with the CLARITY Act’s stalled path through the Senate and the SEC’s own Regulation Crypto Assets proposal. Prediction markets are just the newest front in a fight that’s been running through Washington all year.

What the CFTC Is Doing While the Courts Sort This Out

The Commodity Futures Trading Commission isn’t sitting on the sidelines waiting for a Supreme Court decision. The agency has signaled it wants to build a clearer national framework for prediction markets on its own, including potential amendments to Rule 40.11, the provision governing how new contracts get listed and reviewed. That rulemaking process is a big part of why Robinhood specifically asked the justices to hold off — if the CFTC finishes writing rules that favor federal primacy before the Court rules, the legal fight might resolve itself in the industry’s favor without ever needing a Supreme Court opinion.

It’s a reasonable bet. Regulatory agencies finishing rulemaking often carries more practical weight, faster, than waiting years for litigation to wind through the appeals process. But it’s also a bet that the CFTC’s leadership priorities don’t shift in the meantime, which is never guaranteed in Washington.

What Happens Next

A few concrete things to watch over the coming months:

• Certiorari decision: The Supreme Court has to decide whether to even take the cases. That alone could take until early 2027, though the Court sometimes moves faster on cases with an active circuit split.
• CFTC rulemaking progress: Any formal proposal amending Rule 40.11 would be a signal of where the agency wants this to land, independent of the courts.
• More state action: Expect additional states to test their own gambling authority against prediction market operators while the federal question remains open, the way Nevada and Connecticut already have.
• Platform responses: Watch whether Kalshi, Polymarket, and Crypto.com pull back further in contested states or push forward and dare regulators to enforce against them.

A Simple Way to Think About “Swap” vs. “Bet”

The legal jargon here trips people up, so it’s worth translating. A swap, in derivatives law, is basically a contract where money changes hands based on whether some future event happens — that’s broad enough to cover interest rate swaps, commodity futures, and, arguably, a contract that pays out based on which team wins a game. A bet, under most state gambling law, is defined more narrowly and usually requires a state gaming license to offer legally.

Crypto.com and Robinhood’s argument is essentially: our contracts fit the federal “swap” definition, so federal law should be the only law that applies, full stop. Nevada and New Jersey’s argument is: call it whatever you want, it functions like a bet, and state gambling law was written specifically to cover exactly this kind of product. The Supreme Court, if it takes the case, will have to pick a side — or draw a line somewhere in between that nobody has proposed yet.

Common Mistakes Investors Make Reading This Story

A few things worth correcting before this story gets oversimplified on social media:

• Mistake: “The Supreme Court already ruled.” Not true. As of this writing, the Court hasn’t even agreed to hear the cases yet — it’s still deciding whether to grant certiorari.
• Mistake: “This only affects sports betting apps.” The underlying legal question — federal preemption versus state authority over blockchain-settled financial contracts — has implications well beyond sports contracts, including how other crypto-adjacent derivatives eventually get classified.
• Mistake: “Robinhood and Crypto.com are on opposite sides.” They’re not. Both want federal preemption to win; they just disagree on whether to ask the Court to rule immediately or wait for the CFTC’s rulemaking to land first.

What This Means for Your Portfolio

If you hold positions in crypto exchanges with prediction market exposure, or you actively trade on Kalshi or Polymarket, the legal uncertainty here is a real variable — not a headline you can skim past. A fragmented, state-by-state outcome means access risk: a platform you use today could be forced to geofence your state tomorrow, similar to what happened with certain DeFi protocols after past enforcement actions.

A federal-preemption outcome would likely be viewed as bullish for the sector’s legitimacy, since it would put prediction markets on the same clear regulatory footing as traditional futures and options — a status crypto has been chasing across nearly every product category this year, from spot ETFs to stablecoins.

None of this is financial advice, and nobody — including the lawyers arguing these cases — knows exactly how the Supreme Court will rule or whether it takes the cases at all. Treat this as a regulatory risk factor to monitor, not a trading signal. Always do your own research before making investment decisions, and consider how much of your exposure to crypto-adjacent products depends on a legal question that’s still genuinely unresolved.

Frequently Asked Questions

Did the Supreme Court agree to hear the prediction markets case?

Not yet. As of late September 2026, Crypto.com and Robinhood have filed petitions asking the Court to take up the case; the justices still need to decide whether to grant certiorari before any ruling on the merits happens.

What’s the difference between Crypto.com’s and Robinhood’s petitions?

Crypto.com wants the Supreme Court to rule on the merits now. Robinhood wants the Court to hold off until the CFTC finishes its own rulemaking on prediction market contracts, which could resolve the dispute without a court ruling at all.

Why does this matter for crypto specifically, and not just sports betting apps?

Prediction markets increasingly run on crypto infrastructure — stablecoin settlement, blockchain-based platforms like Polymarket, and crypto-native exchanges like Crypto.com and Kalshi. A ruling on federal versus state authority here sets a precedent for how blockchain-settled financial contracts get regulated more broadly.

Has any state already taken action against prediction market platforms?

Yes. Nevada used its Ninth Circuit win to force Kalshi to shut down its offerings in the state, and Connecticut issued cease-and-desist orders against multiple operators, including Underdog, which responded with a countersuit.

What is CFTC Rule 40.11 and why does it keep coming up?

Rule 40.11 governs how the CFTC reviews and can restrict new derivatives contracts, including event contracts. The CFTC has signaled it may amend this rule to build a clearer, more permissive national framework for prediction markets, which is part of why Robinhood wants the courts to wait.

Is trading on Kalshi or Polymarket legal right now?

It depends heavily on your state and which platform you’re using, and that patchwork is exactly what this Supreme Court fight is trying to resolve. This isn’t legal advice — check your own state’s current rules and each platform’s stated availability before trading.
