Ranked by guaranteed profit extraction potential. These aren't "get lucky" bonuses — each offer listed below can be converted to guaranteed cash using matched betting calculators, regardless of the game's outcome.
Sign-Up Offer Rankings — Guaranteed Profit
Guaranteed profit potential
$700–$1,100
Bet up to $1,500 on your first cash bet. If it loses, receive up to $1,500 in bonus bets. Convert those bonus bets at ~70% = $1,050 guaranteed. Even at $700 first bet, the math works cleanly. The largest convertible safety net in the US market.
Guaranteed profit potential
$140–$300+
The $200 bonus bet converts to ~$148 cash at 74% conversion. The 20% deposit match up to $1,000 adds meaningful value if you fund $1,000 ($200 match, with rollover). One of the best multi-component offers in the market.
$200–$2,100
10 consecutive days of up to $300/day first-bet insurance means you can run $300 in bonus bets each day. At 70% conversion that's $210/day × 10 days = $2,100 theoretical max. Most realistic target with sensible stakes: $500–$900.
$250–$700
The "bet $10 get $365" offer is straightforward: $365 in bonus bets converts to ~$270 cash. The $1,000 safety net alternative converts to ~$700 if lost and converted. Choose based on your available hedge liquidity.
Recurring Monthly Promo Rankings
Welcome offers are one-time. The real long-term money comes from daily recurring promos. Here's how the books rank for ongoing monthly yield:
| Sportsbook | Daily Boosts | Avg. Profit/Boost | Monthly Potential |
|---|
| DraftKings | 2–5/day | $5–$15 | $100–$300 |
| FanDuel | 2–4/day | $5–$20 | $100–$400 |
| Caesars | 3–6/day | $4–$12 | $80–$250 |
| BetMGM | 2–4/day | $4–$10 | $70–$200 |
| ESPN BET | 2–3/day | $4–$10 | $60–$180 |
Running all 5 books daily: $410–$1,330/month in recurring profit from boosts alone.
What to Do First
If you have accounts at all major books, start with BetMGM's safety net (highest single-offer value). Then DraftKings' Bet $5 Get $200 (quickest to execute). Then FanDuel's 10-day reset (requires daily attention). Then move to daily boost grinding across all books.
