Predicting, resulting, zeros, and when not to trade
Professional sports bettors assess their bets based on the final betting line rather than just outcomes. The accuracy of prediction markets like Polymarket can be judged using Brier scores, which show how well odds reflect actual outcomes. Polymarket has a low Brier score of 0.0581, indicating its predictions are about 77% more accurate than a coin flip. This raises questions about efficiency and the potential for profit in prediction markets. Many people fall into outcome bias, judging decisions by results rather than the decision-making process. As prediction markets gain popularity and engage more participants, they may provide valuable insights across various topics. For instance, significant amounts were bet on predictions regarding Jerome Powell’s press conference, indicating growing interest in such markets. In broader trading, a potential plan for 24/7 trading may not be favorable, as better prices are often achieved during regular market hours when liquidity is highest. Overall, the landscape of prediction markets and trading is evolving, emphasizing the importance of decision quality over outcomes.
