Prediction market

Why does betting on the future cost more to place than to take?

Imagine you're at a sports game, betting with friends on who will win. You notice that betting on the winning team costs more than betting against them.

The difference in cost reflects the ease of making a bet versus the difficulty of getting others to bet against you, showing the market's liquidity and efficiency at different price levels. The formula behind this concept is the bid-ask spread.

Example

If betting on Team A to win costs 110 and betting against them costs 100, the $10 difference is the bid-ask spread.

Remember this

The bid-ask spread is a measure of market liquidity and efficiency at different price levels.
