Market Odds vs Polls
Polls measure who people say they support; prediction market odds measure where traders put real money. Polling averages update every few days or weeks, while market prices react to news within minutes — including primary results, debate moments, and fundraising reports.

Historically, market prices in aggregate have been well-calibrated — a 70% favorite wins about 70% of the time.
