How much money is bet on the NFL each season?

Americans wagered approximately $30 billion on the NFL through legal sportsbooks during the 2025 season, representing an 8.5% increase from the prior year.

When you add global markets including the UK, where NFL betting volume grew by 60% year-on-year, the true worldwide NFL handle is substantially higher.

What is the most profitable NFL betting strategy based on historical data?

No single NFL betting strategy has been consistently profitable across all seasons without exception. However, historical data highlights several angles with persistent edges over large samples. Backing underdogs against the spread has produced cover rates above 50% in most seasons. The critical caveat is that any strategy must be evaluated net of the bookmaker's margin, which averages 10.15% hold rate across US sportsbooks.

Do NFL underdogs cover the spread more often than favourites?

Over the long run, NFL underdogs cover the spread at rates that hover near 50%. In individual seasons, the split can tilt significantly. The 2025 season was a striking example: underdogs covered at a 56.3% rate (89-69-4 ATS), one of the strongest underdog seasons in recent memory.

What are the key numbers in NFL point spread betting?

How does same game parlay profitability compare to single bets?

Same game parlays carry a substantially higher house edge than single bets or even traditional multi-game parlays.

As you add legs, the win probability drops sharply while the embedded margin compounds.
