Regulated American prediction platform Kalshi faces intense oversight regarding its newly introduced cryptocurrency perpetual futures contracts following social media posts highlighting suspicious activity and alleging artificial trading metrics.
The central point of contention revolves around how healthy market activity is measured, with critics pointing to massive trading turnover relative to the amount of open capital. IcoBeast.eth, who manages product development at Kalshi, stated on X that the accusations arise from misunderstandings concerning the platform’s underlying mechanics.
CoinDesk reached out to Kalshi for supplementary statements but did not secure an immediate response.
The allegation
The controversy started when a quantitative researcher and co-founder of Stealth Neolab known as Beni on X highlighted a significant imbalance within Kalshi’s ether perpetual contract (ETH-PERP). He observed that the instrument recorded $539 million in 24-hour trading volume against an open interest totaling only $3.1 million.
Stated differently, the trading activity was 174 times higher than the open interest. Observers typically view this as a classic indicator of wash trading, where fabricated purchases and sales inflate aggregate volume tallies while the actual capital at risk stays remarkably low.
Open interest defines the cumulative dollar worth of active, unfulfilled contracts at any given moment. Conversely, trading volume denotes the aggregated dollar sum of contracts that physically changed hands during a specific timeframe.
To support his assertions, Beni directed attention toward a distinct sequence of repetitive $5,500 trade amounts that single-handedly generated up to 58% of Kalshi’s overall ether perpetual volume across four separate days. He characterized this pattern as undeniable evidence of volume manipulation.
He also highlighted a fee rebate schedule submitted to the Commodity Futures Trading Commission (CFTC) that could allow particular Self-Clearing Members to achieve a net-zero fee through a 0.3-basis-point maker rebate offset against a 0.3-basis-point taker fee. Fundamentally, his argument suggests that when the expense of trading against oneself falls to zero, the temptation to artificially boost volumes increases.
Within financial markets, rebates act as financial perks, such as partial fee reductions or monetary incentives, granted to high-volume market makers to encourage greater liquidity generation.
The Rebuttal
IcoBeast.eth initially dismissed the wash trading worries on X, noting that the platform’s fee framework should naturally deter bad actors. However, as the discussion gained traction online, he provided a thorough breakdown to clarify the situation.
First, he pointed out a major error in Beni’s initial post, explaining that the Artemis graphic cited within the complaint actually measured prediction-market share rather than perpetual contract volume.
He additionally demystified why Kalshi’s volume metrics appear so large, clarifying that they adopt the exact reporting standard utilized by Polymarket: volume mirrors the maximum potential payout rather than the initial cash layout.
Because each event contract yields precisely $1 to the victor, the sector records volume by tallying the total quantity of $1 outcomes involved. For instance, if a participant acquires 100,000 contracts valued at 30 cents, they invest merely $30,000 in cash, yet the system registers $100,000 in volume because that represents the ultimate aggregate worth of the contracts upon maturity. This naturally inflates the headline volume figures, but it mirrors authentic user demand rather than artificial wash trading.
Shifting focus toward perpetual contracts, IcoBeast forcefully dismissed the notion that Kalshi handpicks an exclusive group of Self-Clearing Members. Per CFTC mandates, fair access is legally enforced, implying that any entity clearing the requisite capital and operational benchmarks has the legal right to participate.
“Separately on perps you claimed that ‘Here SCM means market makers that are selected by Kalshi lmfao.’ This isn’t true. Anyone can become a Self-Clearing Member of a CFTC regulated exchange as long as they meet the regulatory requirements. ‘Fair access’ is a reg requirement for us,” IcoBeast.eth stated.
Furthermore, he emphasized that Kalshi does not extend rebates on its crypto event prediction contracts.
While recognizing that rebate frameworks remain standard practice across prominent venues like CME Group, Hyperliquid, and Binance, he argued that Kalshi’s competitive edge resides in its transparency. As a regulated Designated Contract Market (DCM), Kalshi must legally file all incentive frameworks openly with the CFTC instead of negotiating agreements in secret.
While acknowledging that Kalshi’s U.S. perpetual offering remains in its early stages, he stressed that their regulatory duties guarantee complete openness.
“I’m the first to admit that it’s early days for perps for us given we’re building a new product in untrodden territory (US perps). But the core difference between Kalshi and offshore perp exchanges is that while other exchanges run deals in the dark, we need to file our incentive programs publicly and so what you see is truly what you get,” he observed.
