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)
- 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/
- AGA PDF detail — online sports betting 96.5% of sports GGR; handle +11.0%. https://www.americangaming.org/wp-content/uploads/2026/03/CY-2025_CGRT.pdf
- InGame / state filings, May–Aug 2025 — six states publishing parlay splits: parlays ~29.2% of handle and ~59.8% of operator revenue in that window (hold on those parlays 22.59%). https://www.ingame.com/sportsbooks-summer-slam-2025/
- Legal Sports Report on AGA — implied national hold ~10.2% in 2025 vs 9.2% in 2024. https://www.legalsportsreport.com/263300/sportsbooks-make-more-money-from-slower-sports-betting-growth-in-2025/
2b. Field 80/20 examples

| Hold ~10% of handle kept as GGR nationally | US sports betting | AGA 2025 | Hook |
| ~20% of bets / habits → ~80% of losses (principle) | Recreational betting | Logic + casino cousin | Intro |
3. Original observation (only-on-8020 seed)
A five-bottleneck register: parlay mix, no cap, chase, promo action, same-game soup.
4. Ignored majority (named)
Daily parlays, “boost” slips, live bets after a beer, treating a World Cup night like research.
5. Composite policy
| Scenario | Keep as Illustrative? | Cut instead? |
|---|---|---|
| Bettor who logged 20 slips, most damage on 4 SGP parlays | Yes |
6. Vital few (draft list)
