Crypto perpetual futures came to the US. Read the house edge.

US traders can now buy crypto perpetual futures on regulated venues at home. Kalshi got the first CFTC sign-off on May 29, 2026. Kraken opened its book on June 15. Coinbase followed with nano Bitcoin and nano Ether contracts and leverage capped at 10x. For a decade this product lived offshore, out of reach of American retail and American regulators. Now it has a US address.

The pitch is safety: identity checks, lower leverage, a regulator watching the venue. All of that is real. What the pitch leaves out is the part that does not change with the jurisdiction. A perpetual future is a leveraged bet with a funding fee that runs every few hours and a liquidation trigger that closes you out the moment the price crosses your margin. The venue takes a cut on every open and every close, whichever way the trade goes. That is the house edge. Moving it onshore caps how much rope you get and writes your name next to the position. It does not change who the mechanism pays.

What a perpetual future actually is

A normal futures contract has an expiry date. A perpetual future does not. It runs forever, which means the exchange needs a way to keep the contract price glued to the real spot price. That job falls to the funding rate.

The funding rate is a payment between traders, usually every eight hours. When more money is long than short, the price of the perp drifts above spot, and longs pay shorts to pull it back. When the crowd is short, shorts pay longs. The rate floats with positioning, so a crowded trade costs you rent for as long as you hold it. Hold a leveraged long through a stretch of positive funding and you can bleed out even if the price goes nowhere.

Leverage is the second lever, and the dangerous one. At 10x, you control a position ten times your margin. A 10% move against you erases that margin and the position is liquidated, closed by the exchange at market. Offshore, where caps have run as high as 100x, a 1% wobble does the same thing. Liquidations do not arrive politely. When a cluster of leveraged longs gets stopped out at once, the forced selling pushes the price lower, which triggers the next cluster. The cascade is a feature of the design, not a glitch.

That design is why perps ate the market. Perpetual futures are around 90% of crypto derivatives volume, and derivatives are roughly 80% of all crypto trading. Annual perp volume passed $60 trillion in 2025. Almost none of it touched a US-regulated exchange. Americans who wanted in used offshore venues with no oversight and no recourse.

The engine came onshore

2026 is the year that changed. On May 29, the CFTC approved Kalshi's Bitcoin perpetual contract, the first cleared on a registered US exchange. Kalshi self-certified more than a dozen additional crypto perps and crossed $1 billion in volume inside the first week.

Kraken went live on June 15 through Bitnomial, the derivatives exchange its parent company bought this year. At launch it listed nine assets: Bitcoin, Ethereum, Solana, XRP, Cardano, Chainlink, Dogecoin, Litecoin and Avalanche. Kraken framed the moment as a rerun of the spot Bitcoin ETF, where the sophisticated traders move first and the institutions follow.

Coinbase came next with nano Bitcoin and nano Ether perps on its CFTC-regulated arm, leverage held to 10x, fees starting at 0.02% per contract. Three of the most-used US crypto venues now sell the same leveraged product that used to require an offshore account and a VPN.

The regulated version is genuinely different in three ways. Leverage is capped well below offshore limits. Customers pass identity checks, so the venue is not anonymous. And the exchange sits inside a US legal structure, which means client funds and dispute rules exist on paper. For anyone who was going to trade perps regardless, an onshore venue with those guardrails beats an offshore black box.

Who the mechanism pays

Here is the part the launch coverage skips. Perps are close to a zero-sum game among traders, and the venue charges a fee on every trade. In a zero-sum market with a toll on each transaction, the average trader loses the toll. That is arithmetic, not pessimism.

Walk the money. Funding moves from one side of the trade to the other, so as a group traders net out to zero on funding. Fees do not net out. Coinbase's 0.02% sounds trivial until you remember leverage multiplies your position size, so the fee is charged on the full leveraged notional, not on your margin. Open and close a 10x position and you pay the toll on ten times your stake, twice. Trade often, as leveraged traders do, and the fee compounds against you fast.

Liquidations are the other revenue line. When your position is force-closed, the exchange's liquidation process takes over, often with a penalty, and the venue and its liquidity providers stand on the profitable side of that transaction. High leverage raises the odds you get there. This is why the same Better Markets warning that flags retail risk also describes a product that reliably transfers money from impatient, leveraged traders to the venues and the patient counterparties on the other side.

None of that improves when the exchange gets a US license. A lower leverage cap slows the bleed by shrinking position sizes, which is real protection. It does not flip the sign of the expected value. The house edge is structural. Regulation trims the size of the bets, not the direction of the drift. If you have read our teardown of what regulated crypto wrappers actually pay out in Morgan Stanley's staking ETFs, this is the same lesson from the other side: the wrapper changes the packaging, not the underlying math.

What the CME fight is really about

The onshore move has already triggered a turf war. On June 18, 2026, CME sued the CFTC and its chairman, arguing that perpetual futures are not futures at all. CME's claim is that perps meet the legal definition of swaps, which would drag them under heavier dealer registration, capital and reporting rules.

Read the incentive. CME runs a $3 trillion crypto futures complex built on the traditional, expiry-dated contracts it already dominates. The new perp venues are on its turf with a product retail traders actually prefer. Reclassifying perps as swaps would raise the cost of offering them and hand the advantage back to the incumbent with the compliance department already built. The lawsuit is dressed as a question of statutory definitions. Underneath, it is an exchange trying to raise the drawbridge on the challengers.

How the court rules matters for anyone trading these contracts. A win for CME could push perps back behind swap-dealer rules, thin out the number of venues, and widen spreads. A loss keeps the door open and the competition on. The same CFTC that is racing to bring crypto onshore is now the defendant in the case deciding how that market is built. This is the market-structure fight worth tracking, in the same lane as Binance.US pushing into CFTC-regulated prediction markets, where the license is the whole game.

Who this is for, and what to watch

Regulated perps are a tool for traders who already understand funding rates, margin and liquidation, and who want US recourse instead of an offshore account. If that is you, the onshore venues are a clear upgrade on what you were using before.

They are not a savings product, not passive income, and not a place to park money you cannot lose. A leveraged perp held without a plan for funding and liquidation is a countdown, and the regulator's stamp does not pause the clock. The cap at 10x is a smaller gun, not a safe one.

Watch three things over the rest of 2026. First, the CME case, which decides how many venues survive and at what cost. Second, the leverage caps, since any venue that lifts them toward offshore levels is dialing the risk back up. Third, the funding rates on the new US books, which tell you which way the crowd is leaning and what it costs to sit against it. The engine that drove 90% of crypto trading now has an American address. The mechanics that made it an engine came with it.
