Kalshi’s $300m stock perps debut meets Cboe & Citadel suit
Cboe & Citadel Securities say funding payments on the perps make them swaps, triggering tougher rules.
The hit
Kalshi launched single-stock perpetual futures on 50-plus NYSE & Nasdaq names on 5 November, reporting more than $300m in volume within hours, according to Barchart. Cboe & Ken Griffin’s Citadel Securities have sued, arguing the contracts are swaps, not futures, a classification that would impose stricter margin & reporting rules.
Why it matters
If Cboe & Citadel win, Kalshi’s retail-friendly design, small contract sizes & capped leverage, could face swap-level capital & margin rules that limit retail access. The case lands as Democrats take Congress & Kalshi fights gambling-related actions in multiple states.
The record
| Launch volume claimed | $300m-plus across 50-plus stocks (Kalshi, self-reported, 5 Nov) |
|---|---|
| SpaceX contracts | ~$88m in 24-hour volume, nearly 30% of launch tally |
| Leverage cap | ~5x, versus 50x-100x on offshore crypto perps |
| Legal challenge | Cboe & Citadel Securities suit claims perps are swaps under Dodd-Frank |
| Parallel case | CME Group suit over crypto perps makes the same swap argument |
| State actions | Kalshi fighting gambling-related actions in 20-plus states, including Arkansas & Utah |
What happens next
Watch the court’s ruling on whether perpetual funding payments meet the swap definition, a dispute Barchart says could reach the Supreme Court. Kalshi is also filing with the SEC to speed listings for newly public stocks.
