1. Concentration claim (one sentence)

In sports betting, a small share of bet types and habits - parlays, chase bets, no stop - concentrates most of the sportsbook’s hold and most of a recreational bettor’s damage.

2. Hard anchors (2–5)

  1. AGA Commercial Gaming Revenue Tracker, CY 2025 — Americans legally wagered $166.94B; sportsbook GGR $16.96B (+22.8%); hold rose to ~10.16%. https://www.americangaming.org/commercial-gaming-revenue-hits-78-7-billion-in-2025-driving-record-18-1-billion-in-gaming-taxes-nationwide/
