Comment on CFTC-2026-0331, CFTC-2026-0331-0001, Arjun, Sawai

Summary: Arjun Sawai of Kalshi submits a comment in support of "Mentions Markets," arguing that these cash-settled, fully-collateralized binary contracts are a legitimate and economically meaningful category of event contracts. The commenter argues that these markets aggregate existing institutional demand for information on public speakers and that current regulatory frameworks (including CEA Core Principles and existing anti-fraud rules) are sufficient to manage any associated risks.
