Consensus % is how many tracked traders hold a side, not a win probability.
17.5¢ price + 1.0¢ spread + 0.8¢ fee (Sports 5%). Win more often than this and the bet pays.
A market order pays the taker fee and crosses the spread (assumed 1.0¢); a limit order pays no fee but may not fill. The fee category is a guess from the title.
