Kalshi faces ‘fake crypto volume’ allegations as critic flags identical $5,500 trades

Kalshi’s crypto perpetual contracts are under scrutiny after a quantitative analyst flagged what he described as a $539 million 24-hour trading volume on an ether perpetual alongside only $3.1 million in open interest, and highlighted repetitive $5,500 trades that he said accounted for a large share of volume. Kalshi staff responded that the headline volume metric follows an industry convention that counts maximum potential payouts rather than cash exchanged, and pointed to public CFTC filings as evidence of transparency around fees and incentives.

Kalshi faces ‘fake crypto volume’ allegations as critic flags identical $5,500 trades

Why It Matters

The dispute centers on how trading activity is measured and whether platform mechanics or fee schedules can create incentives for wash trading — concerns that affect market integrity and regulatory scrutiny for a U.S.-regulated venue offering crypto perps. Kalshi’s regulatory status and required public filings mean its fee and incentive structures are publicly disclosed, making the debate about interpretation of reported metrics especially relevant.

Key Facts

Alleged 24-hour volume: $539 million (ETH perpetual contract)
Open interest reported: $3.1 million
Repetitive trade size cited: $5,500 trades accounted for up to 58% of ether perpetual volume on four days
Rebate schedule noted: 0.3-basis-point maker rebate offset by a 0.3-basis-point taker fee (CFTC filing referenced)
Platform: Kalshi (regulated U.S. Designated Contract Market)

A quantitative analyst on X (Beni of Stealth Neolab) raised alarm over Kalshi’s newly launched ether perpetual futures, saying the contract showed $539 million in 24-hour trading volume versus just $3.1 million in open interest — a ratio he described as indicative of wash or fake trading. He pointed to a pattern of repeated $5,500 trades that he said made up as much as 58% of the contract’s volume across several days, and highlighted a CFTC-filed fee schedule that could leave some Self-Clearing Members with a net-zero fee, which he argued might remove a disincentive to self-trade.

Kalshi personnel responded on social media, saying the claims stemmed partly from a misunderstanding of how the platform reports volume. They explained Kalshi (like other prediction-market venues such as Polymarket) counts volume as the maximum potential payout of contracts rather than the cash actually spent to buy them. Under that convention, buying contracts with a $100,000 maximum payout at a fraction of that price will be recorded as $100,000 of volume even though the buyer paid less in cash, which inflates headline volume metrics relative to cash turnover.

On the fee and access questions, Kalshi staff pushed back against the notion that the exchange curates a closed set of Self-Clearing Members. They noted that under CFTC rules, firms that meet capital and operational requirements can clear on a regulated exchange, and emphasized that Kalshi must file incentive programs publicly with the CFTC. The company’s representatives also said Kalshi does not offer rebates on its crypto event prediction contracts and that its baseline fee structure is designed to deter volume manipulation.

The controversy highlights two related tensions as regulated U.S. venues roll out crypto derivatives: how to interpret and present market metrics that differ from cash-based measures, and how fee or rebate structures might affect trading behavior. Kalshi’s defenders point to its regulatory obligations and public filings as constraints that promote transparency; critics say observed trading patterns and the fee filing warrant close scrutiny. CoinDesk contacted Kalshi for additional comment but did not receive an immediate response.
