More Accurate Than Polls

Why are MarketsMore Accurate than Polls?

• Polls average over individual opinions and do not engage the intellect.

• Markets engage people into a conversation with one another and forces them to come to a consensus (aka the trading price).

Prediction Markets Help Most When:

• Information/expertise is distributed among many, hard to gather, or difficult to verbalize (implicit knowledge).

• New information comes in continuously, requiring frequent updates of forecasts.

• Information is subject to various interpretations.
