Kalshi's $300 Million Stock-Perps Debut Was Led by SpaceX, But a Cboe-Citadel Lawsuit Could Rewrite the Rules

rediction market operator Kalshi launched single-stock perpetual futures on Nov. 5 across more than 50 NYSE- and Nasdaq-listed names, claiming more than $300 million in volume within hours of a quiet launch, a figure that is self-reported rather than audited and that was dominated by SpaceX-linked contracts.

Perps tied to SpaceX (SPCX) led early trading at roughly $88 million in 24-hour volume, equal to nearly 30% of Kalshi's headline launch tally even though the two figures cover different windows, which shows that demand clusters around high-attention names.

The roster of single-stock perps also includes Palantir (PLTR), Meta (META), Nvidia (NVDA), and McDonald's (MCD), making the rollout the most direct challenge yet from the prediction-market cohort to the incumbent equity-derivatives establishment.

How Kalshi's Stock Perps Work

The structure of Kalshi’s single-stock perpetual futures is retail-friendly by design, with each contract representing 0.02 shares, settling in cash, and staying tethered to the underlying stock through a daily 4:00 p.m. ET funding payment, which is the periodic transfer that keeps a never-expiring perpetual contract priced near the stock.

Leverage is capped near 5x, well below the 50x to 100x common offshore. That positions the product as a lower-octane, regulated cousin of crypto-style perps.

Micron's Plunge Set the Stage

The timing is notable because Micron (MU) fell 23% in two days after the midterm elections amid a broad AI-sector selloff, which is exactly the kind of volatility that draws leveraged speculators to frictionless shorting tools.

The CFTC cleared the products as security futures under joint CFTC and SEC oversight, and Kalshi is already filing with the SEC to shorten listing timelines for newly public companies.

That SEC filing signals Kalshi intends to push the product toward fresh listings quickly rather than wait for the legal fight to settle.

Futures or Swaps? Cboe and Citadel Sue

An alliance that includes Cboe (CBOE) and Ken Griffin’s Citadel Securities has sued, arguing that perps are functionally swaps rather than futures. The industry heavyweights claim that perpetual funding payments meet the Dodd-Frank definition of a swap, a classification that would trigger stricter margin, capital, and reporting rules and limit retail access.

CME Group's (CME) parallel suit over crypto perps reinforces that position, while regulators frame the litigation as protectionism by incumbents trying to avoid competition.

If the alliance prevails, the retail-friendly design, with its tiny contract sizes and accessible leverage, could be the first casualty of swap-level requirements.

The Incumbents Have a Point

Both sides hold legitimate ground, since the incumbents face real competitive pressure for retail flow even as they present themselves as guardians of market safety.

Still, their warnings about auto-liquidation cascades, round-the-clock margin calls, and price gaps at market reopening describe substantive structural risks rather than mere talking points.

Political Winds Shift Against Kalshi

The political backdrop has shifted decisively against the upstarts, with Democrats taking control of Congress and intensified oversight likely next year.

Kalshi is already fighting gambling-related actions in more than 20 states, including Arkansas and Utah, which adds a state-level front to the federal classification battle.

Early volume figures should be treated as provisional until the classification question is resolved in court, a dispute that could ultimately reach the Supreme Court.

Until then, Kalshi's $300 million debut is less a verdict on retail demand than an opening bid in a fight over what a perpetual future legally is.
