Definition
A proposition (prop) bet is a wager on a specific event or statistic within a game, rather than the final outcome. Props can be on individual players (Patrick Mahomes over 275.5 passing yards) or game events (first team to score, total touchdowns). Props often have higher vig but can offer +EV opportunities.
Example
Player prop: Josh Allen over 35.5 rushing yards (-115). Game prop: Will there be a safety? Yes +800, No -1400. First touchdown scorer: Travis Kelce +650.

How do prop limits compare to main lines?
How do prop limits compare to main lines?
Prop limits are typically much lower—$250-$1000 at most books compared to $5000+ on spreads. This is because books are less confident in their prop lines and need to limit exposure.
