Do Betting Markets Sense a Goal Coming? Evidence from the German Bundesliga

2025-05-27

AI Summary

This study investigates whether football betting markets can anticipate the first goal in Germany’s Bundesliga prior to its occurrence. Leveraging full-season, 1-Hz high-frequency odds and stake data, we employ high-resolution time-series analysis, multivariate regression, and state-space modeling (SSM) to characterize latent market activity and systematically identify dynamic adjustments in bookmaker odds and bettor wagering preceding the first goal. As the first empirical study examining ex-ante expectations for a “high-impact yet unobserved event,” it addresses a critical gap in event-study literature—namely, the identification of the “expectation window.” Results indicate no statistically significant anticipatory response in either odds adjustments or betting volume prior to the first goal, providing no evidence that the betting market possesses reliable pre-event predictive capacity.

Abstract

We use the fertile ground of betting markets to study the anticipation of major news in financial markets. While there is a considerable body of literature on the accuracy and efficiency of betting markets after important in-match events, there are no studies dealing with the anticipation of such events. This paper tracks bookmaker odds and betting stakes to provide insights into the movement of both prior to goals. Utilising high-resolution (1 Hz) data from a leading European bookmaker for a full season of the top German football league, we analyse whether market participants anticipate major news. In particular, we consider the case of the first goal scored within a match, with its strong impact on the match outcome. Using regression models and state-space models (SSMs) accounting for an underlying market activity level, we investigate whether the bookmaker adjusts odds and bettors tend to place higher stakes on the scoring team right before the first goal is scored. Our results indicate that neither side of the market anticipates goals by significantly adjusting their behaviour.

Problem

• Investigates if betting markets anticipate goals before they occur
• Analyzes bookmaker odds and stakes movement prior to first goals
• Tests market participants' ability to predict major in-match events

Innovation

• Uses high-resolution 1 Hz betting data
• Applies regression and state-space models
• Analyzes odds and stakes before goals
