What an edge is worth
worked example · Seattle Sounders FC · Seattle Sounders FC @ Philadelphia UnionKalshi asks 33¢ for a contract the devigged consensus prices at 30.8¢. Drag to size your position:
If it hits
+$3,126
If it misses
−$1,575
Expected value
−$177
That's the honest shape of edge trading: no single bet is a lottery ticket, a repeatable few-percent advantage, compounded over volume, is the entire game. The terminal's job is finding you that advantage before it closes.
