How Over / Under 2.5 Works
"Over 2.5" wins if the match has 3 or more goals; "under 2.5" wins on 0, 1 or 2 goals. The 2.5 line is the soccer staple because matches average ~2.7 goals across the top five leagues — close to a coin flip in most fixtures.
Until Kalshi and Polymarket list dedicated O/U contracts, the strongest free signal is the matchup itself: closely-priced 1X2 markets tend to produce more shots and more goals than lopsided ones, because both sides commit to the attack.
