Kalshi public daily report
Money still sitting in open positions, as opposed to volume, which is money that changed hands. Basis: contracts, valued at each market's own price. Kalshi reports open interest as a contract count; contracts settle between $0 and $1, so the dollar figure is each market's own open interest priced at that market's own price — never a flat $1.
