What something costs is reflective of a balance in the market determined by the amount of demand relative to the supply of goods and services

The prices on prediction markets reflect how the collective forecasts future outcomes

On prediction markets, bettors bid up or down the price of contracts based on what they expect an event's outcome to be. Bettors bid up prices when they think an event is more likely to occur than the current contract price shows, so they buy the contracts, pushing the price higher. They bid down prices by selling these contracts when they believe an event is less likely to occur, driving the price down due to supply and demand.

Falling demand and lower costs of production cause deflation

"Falling demand" refers to anything that changes someone's willingness to spend money on goods and services. Global recessions, fears of a worldwide recession, and a fall in the money supply are all factors that could lead to falling demand. Likewise, lower production costs allow companies to increase production, which can lead to a surplus in supply.

Rather than static prices set by manufacturers or retailers based on the costs of goods, online businesses or box stores with electronic price tags can change prices in real time based on supply, demand, time, location, and competitor prices.
