The first half moneyline, like the standard moneyline wager, is based on the first half outright winner. That is, the team with the most points when they go to the locker room for oranges. Or, if you will, the team that wins the half-time score is considered the winner. However, instead of taking an equal amount of action on both teams, you must bet on one team. This is called "betting the half". The team that wins the half is given 2 points, while the loser gets nothing. So, in the first half, there is no difference between playing Cleveland and Chicago - they are both worth 2.5 points each. But since we bet the half, the team that comes out on top is worth more than that. They get 3 points instead of 2.5. In conclusion, the first half money line is based on how many points a team is worth after they have played one half of football. The winner is the team that scores more points at the end of the half.
