About Sporting Index
Sporting Index took its first bet in 1992 and built the UK's sports spread betting market, where a result is priced as a range to buy or sell rather than a single price. It added a fixed-odds sportsbook in 2019 beside the spreads. Spreadex bought the business in 2023 and runs the two brands as separate platforms.
