Real-world odds

—

No independent base rate yet. Until we connect one (sportsbook consensus, forecasts, the score), the market's own price is the best public forecast, and the fee sits on top of it.

Luck needed meter

90% 😈

Mostly luck. The market itself expects the favorite to lose this often; the fee is the only certainty.

Fee and break-even by purchase price
If you buy at	Fee per contract	On $50	Win rate to break even
30¢	2.0¢	$3.32	32.0%
45¢ (now)	2.4¢	$2.61	47.4%
50¢	2.4¢	$2.38	52.4%
70¢	2.0¢	$1.43	72.0%
90¢	0.9¢	$0.47	90.9%

Resting (maker) orders pay nothing; orders that take liquidity pay the fee. Formula: 9.5% × price × (1 − price) per share on orders that take liquidity (accounts under $10,000 of 30-day volume; 6.95% in a new account's first week and above $250,000). Break-even assumes you hold to settlement; trading out early pays the fee twice.
