What an edge is worth

worked example · Lions · Packers @ Lions

Kalshi asks 58¢ for a contract the devigged consensus prices at 60.1¢. Pick a position size:

Position

431 contracts

If it hits / if it misses

+$175 / −$250

Expected value per trade

+$3

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.

Expected value ≠ guaranteed outcome · fees approximated · variance is real · not betting advice

Lions is priced at 60.1% to win by the devigged consensus, while the Kalshi YES contract asks 58¢ — a +2.1¢ gap per contract before fees. Prices move fast — verify at the venue before trading.
