Streams every order-book change on Kalshi and Polymarket US for every contract the two venues both list — sports moneylines, spreads, totals and team totals, daily high temperatures (same NWS station only) and economics releases (CPI, GDP, Fed and central-bank decisions) — and checks whether buying both sides costs less than the $1 the winner pays, after both venues' taker fees. Accepted = passes the lock-up rule: annualised return ≥ and settles within days (bigger margins may wait longer). Pairs not marked otherwise are exact matches; amber tags flag a rules difference (hover for details). Observe-only: nothing is traded.
