Claim 9: “betting on sports events accounts for as much as 70% of an estimated $4 billion in revenue during the 12 months ended this July”

DISPUTED

The claim states sports betting accounts for 'as much as 70%' of '$4 billion in revenue'. However, Wikipedia evidence explicitly states sports betting constitutes '89% of revenue in 2025', and other web results mention trading volumes in the billions (e.g., $40.1 billion by July 2026), contradicting the $4 billion revenue figure and the 70% percentage.
