CFTC Examines Unusual Trades on Kalshi's Ethereum Perpetual Contract
The Commodity Futures Trading Commission (CFTC) is examining unusual trades on Kalshi's Ethereum perpetual contract: since August, nearly one million trades of almost identical amounts have been recorded. According to data from The Wall Street Journal, over one-third of trades in recent weeks have concentrated around the $5,500 mark, contributing over $5 billion in nominal trades in the past month.
The platform was approved in June to launch Bitcoin and Ethereum perpetual contracts, with cumulative trades reported at about $5.5 billion in the first two weeks. Independent analysis indicates that daily Ethereum perpetual trades are around $539 million, with open interest at approximately $3.1 million, and a turnover of about 174 times; on several trading days, the $5,500 mark accounted for 48% to 58% of nominal trades. On the Bitcoin side, repeated price levels around $2,500 and $5,000 have emerged. The public order book does not disclose trader identities.
Kalshi has denied any wash trading, stating that its rulebook prohibits wash trades without economic purpose and that there is no evidence of such activity. The trades are genuine, with fixed amounts coming from resting orders placed by market makers that are rapidly executed by faster traders, involving hundreds of different traders, and self-trading is structurally blocked. Reports indicate that shareholders and liquidity-related parties include Jump Trading, with market maker Wintermute also participating in rapid trades; Jump claims to profit from proprietary trading, employs anti-wash trading measures, and does not coordinate with others.
A rebate arrangement effective from September 16 allows some self-clearing members to offset their fees and market-making rebates to nearly zero. The CFTC is still reviewing data to decide whether to initiate an investigation, and officials have not commented on whether an enforcement investigation has begun. The prediction market is known for event contracts, and the introduction of perpetual contracts has placed the trading structure under scrutiny.
Market mechanisms determine the authenticity of trades. Buyers require genuine depth for hedging and speculative accounts, while sellers rely on nominal trades to tell a share story in the new perpetual market. Event-driven trades come from publicly executed trades that break out fixed dollar levels. Beneficiaries are those who can prove their positions match trades, while those under pressure are new markets that pile up turnover multiples using rebates and resting orders. Funds do not exit on the announcement date; exits occur when institutions change "trading volume" from a customer acquisition metric to a compliance risk metric.

Kalshi's historical advantage is its CFTC-designated contract market license, turning election and event betting into compliant products. Bringing the same infrastructure to crypto perpetuals is a way to capture trading volume in the crypto space with regulatory identity. Fixed dollar levels and extremely high turnover are typical shapes resulting from market-making incentives and zero net fees: orders can repeatedly print the same face value without needing to wash trade. The regulatory review is not about price fluctuations but whether this printing machine constitutes false activity.
The capital path involves licenses and market-making equity. Companies like Jump exchange capital for liquidity obligations, while the platform uses rebates to drive costs to zero, allowing nominal trades to report billions of dollars within two weeks. Money shifts from small opinion markets in retail prediction to high-frequency ticket printing in perpetual markets. Once the CFTC upgrades its review to an investigation, rebate documents and self-clearing member lists will become part of the evidence chain rather than footnotes to growth stories.
This is analogous to offshore exchanges using wash trading bans, traditional futures exchanges' wash sale prohibitions, and equity market makers being swept out by passive quotes. The industry is in a transition phase from prediction markets to derivatives: event contracts rely on diversity of opinions, while perpetual contracts depend on verifiable positions. The most dangerous aspect of this transition is measuring a new market with old incentives.
Structural changes are a combination of regulatory changes and shifts in pricing power. Trading volume no longer automatically equals market share. The mechanism is: zero fees make repeated printing cheap, and fixed face values make algorithmic orders appear as if from the same hand; regulators can see the shape using public data without needing to know names in advance. Thus, the premium for "U.S. compliant perpetuals" shifts from the license itself to whether the tape can withstand playback.

- Trading volume can be printed, but open interest is hard to fake.
- When fees are zero, repeated ordering becomes the default strategy.
- Licenses can open markets but cannot explain why all face values are the same.
