NEW YORK (AP) — Kalshi will start collecting customer employment information for trading in certain high-risk markets. This move follows incidents of insider trading on platforms like Kalshi and Polymarket. Kalshi will now score markets for insider trading risk and require employment details for high-risk trades. The reforms come following multiple incidents of prediction market traders using insider information to profit off events. Just last week, former Congressman George Santos was investigated for allegedly betting against his attendance at the State of the Union address. In April, a U.S. Army soldier was charged with using classified information to make $400,000 trading on Polymarket.
