Illegal betting operators fund UK sports piracy through advertising
Illegal betting operators reportedly help finance unlicensed sports-streaming sites in the UK, according to estimates from Yield Sec cited in a report dated 16 January 2026. The ten largest pirate sports sites recorded 1.6 billion views in the first half of 2025, while Yield Sec estimated illegal operators represented 9% of the British gambling market.
The reported links between unlicensed betting advertising and pirate streams may affect enforcement priorities and regulated operators’ competitive position.
