Kalshi denies receiving contact from CFTC over trading patterns

Kalshi is pushing back on reports that it faces regulatory scrutiny over trading patterns on its bitcoin and ether prediction markets, saying the Commodity Futures Trading Commission has not opened any formal examination. The dispute centers on nearly one million ether trades placed in similar amounts, which Kalshi attributes to a routine liquidity incentive program rather than manipulation.

• Kalshi spokesperson Elisabeth Diana said the company has not been contacted by the CFTC and believes no formal examination exists.
• The Wall Street Journal reported the CFTC was reviewing Kalshi trading data before deciding whether to open an enforcement investigation.
• Researcher Beni found $5,500-sized trades made up 48% to 58% of notional ether perpetual volume on four days in September.

• $539M Kalshi ether perpetual 24-hour volume versus $3.1M open interest
• $5,500 trade size that dominated ether perpetual notional volume, per Beni
• 48-58% share of notional volume from identical $5,500 trades, four days in September
• ~1M ether market trades placed in similar amounts, per WSJ report

Kalshi said it has not heard from the CFTC and does not believe the agency has launched a formal probe into its trading activity, according to reporting by CoinDesk. The statement came after the Wall Street Journal reported that the CFTC was examining Kalshi trading data before deciding whether to open an enforcement investigation. The CFTC declined to confirm whether such a review was underway.

Kalshi denies formal CFTC examination

Elisabeth Diana, a Kalshi spokesperson, said the company sends trading data to the CFTC as a matter of course and sees nothing unusual in the agency looking at it.

We have not been contacted by the CFTC and don’t believe there is any formal examination.

Diana said the trading patterns drawing attention are “typical of liquidity incentive programs and common in financial markets.” Such programs pay participants for providing liquidity, often producing bursts of similarly sized orders that can look uniform from the outside.

Diana added that Kalshi routinely shares data with the regulator. “We send our data every day to them [the CFTC], and it’s not that weird for them to sort of review our data on the regular,” she said. Asked directly about wash trading protections, Diana said Kalshi has “tons of tools” and a “full surveillance team in place.” Wash trading refers to transactions structured to create the appearance of market activity without any real change in economic exposure.

Beni’s data shows $5,500 trades dominating ether perp volume

CoinDesk reported early Tuesday that a majority of trading volume on Kalshi’s bitcoin and ether perpetual markets consisted of identically sized trades, many ether perpetual trades clustered near $5,500 and bitcoin perpetual trades near $2,500 or $5,000. The Journal’s later report added that the CFTC was reviewing nearly one million ether trades placed in similar amounts before deciding whether to escalate to a formal investigation.

Beni, a co-founder of research firm Stealth Neolab, first flagged the pattern. He said Kalshi’s ether perpetual market recorded about $539 million in 24-hour trading volume against just $3.1 million in open interest, a gap he found notable.

Beni later found that trades of exactly $5,500 accounted for 48% to 58% of notional volume on four separate days in September. He said the figures came from Kalshi’s public API. Kalshi has not disputed Beni’s underlying numbers, only his interpretation of what they mean.

CFTC declines comment as Prediction Market scrutiny grows

The CFTC had not returned a request for comment sent Tuesday, according to CoinDesk. The agency also declined to confirm to the Journal whether it was formally investigating Kalshi.

The scrutiny arrives as prediction markets expand rapidly, drawing closer attention to how platforms report volume and police trading between participants. Diana pushed back on unverified claims spreading online, saying “don’t believe everything you read on X” and adding that “a lot of the discourse was rumors seeded by competitors.”

The BlockWest read. The real question is not whether the CFTC has opened a formal file, but whether Kalshi’s own surveillance team can produce data reconciling $539 million in reported volume against $3.1 million in open interest before the agency asks. Institutional counterparties weighing exposure to Kalshi’s derivatives markets will watch that reconciliation more closely than any denial of contact with regulators.

The CFTC has not said whether its review of Kalshi’s data will proceed to a formal enforcement investigation, and it did not respond to requests for comment from either CoinDesk or the Journal. Kalshi has not published the surveillance data or methodology Diana referenced, leaving Beni’s API-derived figures as the only detailed public account of the trading pattern so far.
