by

What to know:

  • In a revelation that could make even Nostradamus raise an eyebrow, data scientist Alex McCullough’s Dune dashboard shows Polymarket predicting events with a jaw-dropping 94% accuracy! (Extreme probabilities? Who needs ’em?)
  • But hold your horses! Polymarket has a tendency to overestimate event probabilities, thanks to quirks like acquiescence bias, herd mentality, low liquidity, and a penchant for high-risk bets. 🎢
  • Sports markets, with their delightful balance of outcomes, are the shining stars of predictive accuracy, boasting nearly $4.5 billion wagered on major sports finals. Talk about a betting bonanza!

Behold! Polymarket, the modern-day crystal ball, can predict certain events with nearly 90% accuracy, as revealed by the illustrious Alex McCullough from the bustling streets of New York City. 🗽✨

McCullough meticulously sifted through Polymarket’s historical data, discarding markets with probabilities above 90% or below 10% after the outcomes were known but not yet settled. Accuracy is key, after all! 🔍

His findings suggest that Polymarket consistently overestimates event probabilities, likely due to biases like acquiescence bias, herd mentality, low liquidity, and a love for high-risk bets. Who knew betting could be so complicated? 🤔

Longer-term markets, those that ask bettors to gaze into the distant future, appear more accurate. Why? Because they include many outcomes that are clearly unlikely, making predictions a walk in the park! 🌳

For instance, McCullough points to the question of Gavin Newsom becoming president (a staggering $54 million in volume) during the last election. Clearly, Newsom’s victory was as likely as a snowstorm in July, boosting the platform’s accuracy for these long-term predictions. ❄️

In contrast, head-to-head sports markets, with their fewer extreme outcomes and balanced distribution, provide a clearer picture of predictive accuracy. As events unfold, accuracy spikes like popcorn in a microwave! 🍿

Sports betting is booming on Polymarket, with nearly $4.5 billion wagered on the outcomes of the NBA, MLB, Champions League, and Premier League finals. It’s a sports fan’s paradise! ⚽🏀

McCullough’s insights into Polymarket’s accuracy are sure to pique interest in Ottawa, where the new Liberal Party of Canada leader, Mark Carney, is showing a significant lead over his Conservative rival, Pierre Poilievre. Poll aggregators, take note! 📊
