Claims that Kalshi operates a fee structure netting to zero remain unconfirmed, as the exchange's CFTC-filed perpetuals fee schedule from June shows positive maker fees with no rebates. While API data does not disclose counterparties, this pattern alone does not constitute proof of wash trading activity on the platform. Kalshi's crypto lead stated that all incentive programs are publicly filed with regulators. The exchange has not yet responded to inquiries regarding the fee structure allegations and verification requests.
