Break-even at the price47.4%54.3%

Both posted prices together imply more than 100% — that surplus (1.7% here) is what the book keeps. Strip it out and the market makes this SEA 46.6%, BOS 53.4%. The break-even row is the win rate you'd need at the posted price just to tread water — the gap between the two rows is the cost of the bet.

Prices move all day. The live version of this game — score, line movement and the rest of the board — is on today's board.
