Bloomberg LP has announced the addition of Polymarket's US election odds to the Bloomberg Terminal, reflecting the growing interest in blockchain-based prediction markets, especially with the upcoming US presidential election.

Polymarket Integration in Bloomberg Terminal

Polymarket, built on the Polygon blockchain, allows users to bet on various events, including elections, by pooling their judgments to set odds. Michael McDonough, Chief Economist, Financial Products at Bloomberg LP, confirmed the addition, stating: "We are in the process of adding Polymarket data to WSL ELECTION!" Polymarket operates on the concept of the wisdom of the crowd. Users bet on different outcomes, and their combined opinions help set the odds.

Reactions and Impact on Prediction Markets

This market has gained traction, with nearly $760 million in trading volume for the presidential election at press time. The odds show Donald Trump is slightly ahead of Kamala Harris, with Trump holding a 50% chance of winning, and Harris close behind at 48%. These odds change rapidly based on trader sentiment and outside political developments. For instance, Trump's odds recently jumped to 53%, showing bettors' increased confidence in his chances of returning to the White House.

Comparison with Other Prediction Platforms

Compared to other prediction markets like PredictIt, Polymarket usually has more liquidity and offers a wider variety of bets. PredictIt often gets flak for limiting how much people can bet and how many can participate, which can tamper with its accuracy. Polymarket, on the other hand, has higher trading volumes and fewer rules, creating a more flexible market that could lead to better predictions. But Polymarket also had its slip-ups. In Pennsylvania, for example, the odds for a Republican win tanked from 61% to 0% as the results rolled in, showing a big gap between what the market expected and what actually happened.

The integration of Polymarket data into the Bloomberg Terminal provides analysts and investors with a new tool for gauging the outcome of the upcoming elections. This collaboration demonstrates the growing interest in blockchain-based prediction platforms and their relevance in the context of current economic and political events.
