Federal Review Targets $5 B of Unusual Crypto Futures Trades on Kalshi

Core Event: CFTC Examines Kalshi’s Ether Perpetual Futures Activity
The Commodity Futures Trading Commission (CFTC) is reviewing trading data from Kalshi, a U.S.–regulated prediction-market platform that recently added crypto perpetual futures. Regulators were alerted after more than $5 billion of ether-related trades clustered around a single notional size—approximately $5,500—within a single month. The volume-to-open-interest ratio in that market has risen to an unprecedented level, prompting questions about whether the activity reflects legitimate market-making or potential “wash trading,” where a participant simultaneously buys and sells the same asset to fabricate activity.
Trading Patterns That Sparked Concern
A working paper posted by an author using the name “OctopusTakopi” examined roughly 4.1 million Kalshi trades (about $11.5 billion) from early to mid-September. The analysis found that roughly half of the perpetual-futures volume was concentrated in a few fixed-dollar trade sizes, with similar clustering in the bitcoin market. In one notable episode, the dominant trade sizes in both bitcoin and ether markets shifted almost simultaneously, a pattern the author described as consistent with a single operator adjusting parameters across markets. The paper did not identify the trader(s) involved.
Kalshi’s Official Response
Kalshi denies any regulatory inquiry and attributes the patterns to normal liquidity-incentive programs. The company’s spokesperson, Elisabeth Diana, stated:
> “We have not been contacted by the CFTC and don’t believe there is any formal examination,” — Elisabeth Diana, kalshi spokesperson
Kalshi also notes that its rules explicitly prohibit wash trading, that its systems block self-trades, and that it has a history of cooperating with regulators, including referring insider-trading cases to the CFTC.
Outlook: Potential Enforcement Action
The CFTC has not publicly confirmed or denied an investigation, but the agency’s review is ongoing. If regulators determine that the activity violates market-integrity rules, Kalshi could face an enforcement proceeding. Until a formal decision is announced, the platform’s claim that the data reflect “healthy market-making” remains unverified.
