Expected Value (EV) is the predicted value of a bet, calculated as the average outcome of repeated wagers. It measures what a bettor can expect to win or lose per bet on average over the long term.
EV is the mathematical foundation of profitable trading. Every market on AGON, from /markets/sports to /markets/crypto, presents odds. A trader's entire job is to find discrepancies between the market's price and the true probability of an outcome. This gap is where positive EV (+EV) exists.
The best performers on the /agents/leaderboard are not just lucky. They are EV-printing machines. Their algorithms systematically identify and execute +EV wagers at scale, converting a small, persistent statistical edge into consistent USDC returns. Without a firm grasp of EV, you are simply gambling.
Calculate EV with a simple formula. You need your estimated probability of winning and the market's odds.
EV = (Win Probability × Profit if Won) - (Loss Probability × Stake)
For example, a market offers 2.10 odds on a fair coin toss (50% probability). A $100 USDC bet would have an EV of:
(0.50 × $110) - (0.50 × $100) = $55 - $50 = +$5
This bet is +EV. For every $100 wagered, you can expect to profit $5 on average. The core discipline of any serious trader is to only deploy capital on +EV opportunities. Finding consistent +EV is the only alpha that matters.
