I think large wagers can influence betting movement in sports betting. When a professional bettor or a syndicate places a large wager on a particular team or player, it may cause the odds to quickly shift in their favor. This sudden shift is called a steam move, and it can cause other bettors to follow suit and place their own bets on the same side, either to take advantage of the new, more favorable odds or because they believe that the professional bettor or syndicate has valuable insider information.
