Contract prices reflect the crowd\u2019s collective probability estimate of an outcome, settling at $1 if correct or $0 if not.<\/p>\n<p>The model has roots stretching back to <a href=\"https:\/\/en.wikipedia.org\/wiki\/Prediction_market\" target=\"_blank\" rel=\"noopener noreferrer\">19th-century<\/a> election betting on Wall Street, and gained academic credibility in 1988 when University of Iowa professors launched the Iowa Electronic Markets to test whether crowd-sourced contract prices could outforecast traditional polls.

The real inflection came in the 2020s. <a href=\"https:\/\/srt.bitcoin.com\/polymarket-newsart\" target=\"_blank\" rel=\"noopener noreferrer\">Polymarket<\/a> launched in 2020, built on <a href=\"https:\/\/markets.bitcoin.com\/crypto\/polygon\" target=\"_blank\" rel=\"noopener noreferrer\">Polygon<\/a> and settled in USDC.<\/p>\n<p>The next year, <a href=\"https:\/\/srt.bitcoin.com\/kalshi-may\" target=\"_blank\" rel=\"noopener noreferrer\">Kalshi<\/a> received <a href=\"https:\/\/news.bitcoin.com\/senate-democrats-urge-cftc-to-ban-sports-and-election-contracts-on-kalshi-and-polymarket\/\">CFTC<\/a> approval as a Designated Contract Market in 2021, becoming the first federally regulated prediction exchange in U.S. history.
