Abstract

This study aims to compare the betting odds and diversity offered by legal bookmakers in Türkiye and a bookmaker based abroad, which is considered illegal. The survey model, one of the quantitative research methods, was used. A total of 464 competitions played in the top and one lower league in the football leagues of six different countries were included in the study. The included competitions were analyzed regarding match result odds and number of bets. The data were collected between August 18 and Sep-tember 18, 2024. The data set was found to be normally distributed, and ANOVA and Posthoc LSD tests were used for analysis. It was found that the odds and variety of bets offered by illegal bookmaker were significantly higher than the monopoly Main Legal Bookmaker and all six different online bookmakers. This situation is attributed to the monopoly dominance of the betting market in Türkiye. Opening the market to compe-tition through licensing would provide consumers with more attractive prices and ser-vices.
