REGULATORY DECISIONReport: CFTC Eyes Unusual$5B Trading Pattern on KalshiETH Perpetuals44IMPORTANCEQUIET2NEWS MEDIA2PIECESSep 24, 2026 01:00blockboard.net

Kalshi said nearly $5 billion of similarly sized Ether perpetual trades were tied to its liquidity incentive programs and denied that the activity was wash trading. Another report said the CFTC is reviewing unusual trading on Kalshi’s Ethereum perpetual futures market, with close to one million trades clustered around the same $5,500 order size since August.

What this rests on

Claim by claim, with its source
✓
The CFTC is reportedly reviewing unusual trading on Kalshi’s Ethereum perpetual futures market.
✓
The Wall Street Journal found close to one million trades clustered around the same $5,500 order size since August.
✓
Kalshi said nearly $5 billion in similarly sized Ether perpetual trades reflected its liquidity incentive programs.
✓
Kalshi rejected allegations that the activity was wash trading.

What it means

Who it affects, what changes and what is still unconfirmed

Each sentence links inside to the piece that supports it.

Kalshi users and traders who interacted with the Ether perpetual market would notice that the trading pattern is being described publicly as unusual, while Kalshi says the activity fits its liquidity incentives. That leaves the market’s recent activity under scrutiny today, even though the company has said the trades were not wash trading.

In practice, the market can still show large volumes of similarly sized trades, but the question now is whether that pattern is being examined by the CFTC. The trading itself is not described as having stopped, and the size clustering around $5,500 remains part of the reported activity.

Market reaction

We track ETH, but we only have 1 price point in that window. The series is stored every half hour, so newer events will have it. Computing it from two points would not be a reaction, it would be a coincidence.
