Kalshi denies CFTC investigation, calls repetitive ether trades a liquidity-program artifact

Prediction market Kalshi says it is not under regulatory investigation over its trading activity, pushing back on reports that the U.S. Commodity Futures Trading Commission (CFTC) was examining unusual patterns in its ether perpetual market.

"We have not been contacted by the CFTC and don't believe there is any formal examination," Kalshi spokesperson Elisabeth Diana said in a statement reported by CoinDesk on Sept. 23. "As we've said, these data patterns are typical of liquidity incentive programs and common in financial markets."

The denial responds to a Wall Street Journal report, published Tuesday, that the CFTC was reviewing trades on Kalshi before deciding whether to open an enforcement investigation. Per CoinDesk's account of the WSJ story, the review followed nearly one million trades in an ether market placed in similar amounts. The CFTC declined to confirm whether an investigation was underway and, per CoinDesk, had not returned a request for comment.

The patterns themselves were first flagged by Beni, a co-founder of research firm Stealth Neolab, who — citing figures he said came from Kalshi's public API — reported that the ether perpetual recorded roughly $539 million in 24-hour volume against just $3.1 million in open interest. He later found trades of exactly $5,500 made up 48% to 58% of notional volume on four separate days in September. CoinDesk's own analysis found a majority of volume on Kalshi's bitcoin and ether perpetual markets was composed of identically-sized trades — ether clustered near $5,500, bitcoin near $2,500 or $5,000.

Diana attributed the clustering to Kalshi's liquidity incentive program, which rewards participants for providing orders. She said Kalshi sends data to the CFTC daily and that periodic review "is not that weird." Asked about wash trading and self-trading safeguards, she said the exchange has "tons of tools" and a "full surveillance team in place," and dismissed online speculation as "rumors seeded by competitors."

Key facts

• Kalshi denies CFTC contact or a formal examination (Kalshi's Elisabeth Diana, via CoinDesk, Sept. 23).
• WSJ reported the CFTC was reviewing Kalshi trades ahead of a possible enforcement decision, after ~1 million similarly-sized ether trades (WSJ, via CoinDesk).
• Ether perpetual: ~$539M 24-hour volume vs. $3.1M open interest; $5,500 trades were 48–58% of notional on four September days (Beni / Stealth Neolab, citing Kalshi's public API, via CoinDesk).
• CoinDesk's analysis: identically-sized trades dominated bitcoin and ether perpetuals.
• The CFTC declined to confirm any investigation and did not respond to CoinDesk.

The real-world read

Two things can both be true, and only one has been independently checked. The trade-clustering — a lopsided volume-to-open-interest ratio and half of notional in one exact size — is documented from Kalshi's own API by an outside researcher and corroborated by CoinDesk. Kalshi's explanation for it, and its claim that no examination exists, come entirely from the company; the CFTC's silence neither confirms nor denies. A volume figure 170 times larger than open interest is exactly the shape wash trading produces, which is why the "liquidity incentive" framing is doing heavy lifting here — it's the interested party's account, not a regulator's finding. And attributing scrutiny to "rumors seeded by competitors" deflects from data Kalshi publishes itself.

Opinion, and whose

Kalshi (via Diana) characterizes the patterns as normal market-making and the reports as competitor-driven rumor. Beni/Stealth Neolab treats the ratios as anomalous enough to publish. No regulator has stated a view on the record.
