It counts every dollar staked before any winnings are paid out. Handle is not the sportsbook’s revenue. Revenue equals handle minus payouts, and the hold (or win rate) is revenue divided by handle. Quick example: if bettors place $200 million in wagers and sportsbooks pay out $188 million, revenue is $12 million and the hold is 6%.
