Odaily Planet Daily reports that quantitative analyst Beni posted on X that the open interest for Kalshi ETH-PERP is currently approximately $3.1 million, with a 24-hour trading volume of $538.6 million, equivalent to an average daily turnover of about 174 times the total open positions, with one turnover occurring every 8 minutes and 18 seconds on average; the largest single position is approximately $17,600.
Beni stated that documents previously submitted by Kalshi to the CFTC showed that eligible self-clearing member market makers receive a rebate of 0.3 basis points, while takers pay 0.3 basis points, resulting in a combined trading cost of 0 basis points. He also mentioned that Kalshi had previously entered into an arrangement with Jump Trading to exchange liquidity for equity, and questioned whether the platform’s practice of reporting trading volume in terms of contract count displayed with dollar symbols could be misleading.
