The Glücksspielstaatsvertrag (GlüStV) is the German State Treaty on Gambling administered by the Gemeinsame Glücksspielbehörde der Länder (GGL). The framework was overhauled in 2021 to permit licensed online sports betting and online casino products under specific operator licensing.
The GGL licenses sports betting operators (Tipico, Bet365 Germany, others) and online casino operators under strict consumer protection rules including deposit limits, time tracking, self-exclusion, and connections to the OASIS national self-exclusion register. Licensed German sports betting operators offer event-style markets on football (especially Bundesliga, Champions League, and major international competitions), tennis, motorsport, and other sports.
The framework does not yet have specific rules for prediction markets and event contracts as a distinct category. International decentralised prediction platforms like Polymarket continue to operate accessibly in practice. German users who participate in international prediction markets should consult tax professionals about specific reporting obligations on prediction market activity.
Tax treatment of gambling and prediction market winnings in Germany varies depending on whether activity is classified as professional or hobby trading. German tax authorities have historically taken a more restrictive view of professional gambling activity than some other European jurisdictions. Casual users with small prediction market activity typically face simpler tax treatment than professional traders.
