Prediction Market Perpetual Futures: What Traders Need to Know

Something significant happened this week, and most people in the prediction market space haven't fully processed it yet.

On April 21, Polymarket announced it is launching perpetual futures contracts. Within 24 hours, The Information reported Kalshi is doing the same. Two of the biggest prediction market platforms in the world — both valued in the billions — announced the same structural product shift within a day of each other. That's not a coincidence. It's a signal about where this industry is heading.

If you trade on Kalshi, Polymarket, or both, here's what this means for you in plain terms.

What Is a Perpetual Future?

Standard futures contracts have an expiration date. A farmer and a buyer agree on the price of wheat to be delivered at harvest — the contract ends when delivery happens. Even the financial futures you see on CME Group or the Chicago Board of Trade are tied to a specific date.

Perpetual futures have no such date. They never expire.

Instead, the positions stay open indefinitely. A few times each day, traders on both sides of the position "settle up" — a process called the funding rate — based on the current price of the underlying asset. If you're long and the price moves against you, you pay. If you're right, you collect. And then you keep going, day after day, for as long as you want to hold the position.

Darrell Duffie, a finance professor at Stanford University, summed it up simply: "They never mature. There's no final date. You just keep paying based on price movements."

Perpetual futures have been a dominant product in the crypto derivatives world for years. Last year, the estimated global trading volume for crypto perpetual futures on offshore exchanges crossed $80 trillion, according to CoinGecko's annual report. That number is hard to fathom. For context, the total US stock market trades roughly $400 billion per day. Perps are a huge market — and until now, they've operated almost entirely offshore and outside formal US regulation.

Why Are Kalshi and Polymarket Both Moving Now?

The regulatory door just opened.

The Commodity Futures Trading Commission — the federal body that oversees derivatives markets and regulates both Kalshi and Polymarket's core event contracts — signaled in late April 2026 that it is opening the door to onshore perpetual futures. This is a meaningful shift. The CFTC had been deliberately quiet on the subject for years. The fact that both Kalshi and Polymarket announced their perps plans within days of that signal is not a coincidence — they've clearly been building toward this for some time.

Campbell Harvey, a finance professor at Duke University, made the case for why this matters: "The most significant benefit of onshoring perpetual futures is that it is regulated." On offshore crypto exchanges, there's no guarantor, no oversight, and limited recourse when things go wrong. Bringing perps inside a CFTC-regulated environment changes that calculus significantly.

For Kalshi — currently valued at $22 billion — this fits a broader pattern of pushing into crypto-adjacent financial products while defending its sports markets against a wave of state-level legal challenges. For Polymarket, valued at $15 billion and running on blockchain infrastructure, perps are a natural product extension for a platform that already attracts crypto-native traders and is planning its own token.

Both companies are also in hiring mode. Kalshi is recruiting traders from traditional finance on salaries up to $250,000. Polymarket has been actively recruiting from hedge funds and high-frequency trading firms. Perpetual futures require exactly the kind of infrastructure and talent these companies are building.

What This Means for Prediction Market Traders

If you're trading event contracts today — whether you're positioned on the 2026 midterms, NBA Finals prices, or Fed rate decisions — here's how the perps announcement changes your landscape:

New markets, new instruments. Kalshi's perps will initially be tied to cryptocurrency prices, primarily Bitcoin. If you're already comfortable analyzing probability in event markets, the mechanics of a perpetual futures position aren't dramatically different — you're still expressing a directional view. What changes is the time horizon. There's no contract expiry forcing you out of a position.

Leverage becomes a real variable. On existing crypto exchanges, perpetual futures can be leveraged up to 50 times the collateral you put up. That means a 2% move in the wrong direction can wipe out the position entirely. Under CFTC regulation, it's likely that leverage limits will be significantly lower than offshore markets — but how much lower remains unclear. Ben Schiffrin, director of securities policy at the nonprofit Better Markets, has raised concerns specifically around this point: "Retail investors are unlikely to understand the risks."

This is worth taking seriously. Event contracts on Kalshi and Polymarket are straightforward — you buy a Yes or No share between $0 and $1. Perpetual futures with leverage are a structurally different beast. If you're new to the prediction market space, there's no reason to start with perps. Event contracts are the right entry point.

Cross-platform pricing gaps will matter even more. This is where aggregation becomes genuinely valuable. When both Kalshi and Polymarket offer the same perpetual futures product — say, a Bitcoin perp — their prices will diverge at different moments in the day. The funding rates will differ. The liquidity depth will differ. Understanding where the best price sits at any given moment, across both platforms simultaneously, is exactly the kind of edge that cross-platform data provides.

The Regulatory Questions That Still Aren't Resolved

It's worth being direct about what we don't know yet.

The CFTC has signaled it is open to onshore perpetual futures. It has not published formal rules for how they'll operate. The details matter enormously: what leverage limits apply, how margin requirements work, what happens during extreme volatility, and how disputes are resolved.

Kalshi is already navigating a patchwork of state-level challenges — Nevada issued a temporary ban in March 2026, while Arizona, Tennessee, Illinois, Connecticut, and Massachusetts have all raised objections to its sports contracts under state gaming laws. Adding a product as structurally complex as leveraged perpetual futures to that environment introduces new regulatory surface area.

Polymarket's regulatory history adds another layer of complexity. The platform was forced to exit the US in 2022 after a CFTC enforcement action and a $1.4 million penalty. It returned following federal re-approval in late 2025. The system it uses to resolve prediction market disputes has also drawn regulatory scrutiny. Moving into perps doesn't make those questions disappear.

The broader point: perpetual futures entering the regulated US market is a significant development for the space. But the regulatory picture is still being drawn. Traders who engage with these products early should do so with full awareness that the rules are still being written.

How to Track What's Happening Across Platforms

The prediction market landscape now includes event contracts, sports markets, financial contracts, and soon perpetual futures — spread across Kalshi, Polymarket, Manifold, and others. Each platform has different prices for the same underlying event at different times. The spreads between Kalshi and Polymarket on major markets routinely hit 3 to 7 percentage points.

Tracking that manually across four browser tabs is how most traders still operate today.

You can see every platform's prices on the same event in one view, track whale activity across markets in real time, and spot cross-platform gaps as they open — at predictions.io.

As perpetual futures roll out across these platforms, the case for having a single view of the full landscape only gets stronger.

The Short Version

Kalshi and Polymarket both announced perpetual futures within 24 hours of each other this week. The CFTC opened the regulatory door. These products have no expiration date, involve leverage, and carry significantly more complexity than standard event contracts. They bring $80+ trillion in offshore crypto derivatives activity into a regulated US framework — with all the opportunity and risk that implies. Pricing differences across platforms will matter more, not less, as both Kalshi and Polymarket launch competing versions of the same product.

Watch this space closely. The prediction market landscape is moving faster than most people realize.
