Award shows, reality TV and streaming-hit markets resolve from the official broadcaster announcement or industry body (the Academy for the Oscars, the EBU for Eurovision, Nielsen for US ratings). Because these events have moderate liquidity but high public interest, odds can move sharply as finalists are announced or critics' picks go public. PolyGram routes your order into the same Polymarket order book with a single-tap trading UX.
