It turns out Polymarket is a crystal ball, which can predict certain events with nearly 90% accuracy, according to a Dune dashboard compiled by New York City-based data scientist Alex McCullough.<\/p>\n

\"\"<\/p>\n

McCullough studied Polymarket’s historical data and removed markets with probabilities above 90% or below 10% after outcomes were already known but not yet settled, to keep the analysis accurate, according to a Dune dashboard summary.<\/p>\n

Polymarket slightly but consistently overestimates event probabilities across most ranges, potentially due to biases like acquiescence bias, herd mentality, low liquidity, and participant preference for high-risk bets, McCullough’s research found.<\/p>\n

Longer-term markets, ones that ask bettors to consider an event far-out, look more accurate because they include many outcomes that are clearly unlikely, making predictions easier, McCullough explained in an interview with Polymarket’s The Oracle blog<\/a>.<\/p>\n

McCullough gives the example of Gavin Newsom becoming president (a question with $54 million in volume) during the last election to show that longer-term Polymarket markets often include obviously predictable outcomes, like Newsom clearly not winning, which boosts the platform\u2019s accuracy numbers for these long-term predictions.<\/p>\n

In contrast, head-to-head sports markets, which have fewer extreme outcomes such as long-shot presidential candidates, and a more balanced distribution, present a clearer representation of predictive accuracy, McCullough found, showing notable improvements in accuracy as events unfold and revealing periodic accuracy spikes.<\/p>\n

Sports is a growing sector for Polymarket, with nearly $4.5 billion in collective volume wagered on the outcomes of the NBA, MLB, Champions League, and Premier League finals, according to data portal Polymarket Analytics.<\/a><\/p>\n

McCullough’s findings about the accuracy of Polymarket are likely to be of interest in Ottawa, where Polymarket shows<\/a> that new Liberal Party of Canada leader Mark Carney now has a significant lead<\/a> over his Conservative rival Pierre Poilievre, even more than what poll aggregators are showing<\/a>.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
