> It is not illegal to have a monopoly; but it is illegal to use a monopoly you have in one area to get an unfair advantage in another.
This is a very common misconception in the United States. It’s how a lot of defenders of antitrust law want antitrust law to work, but it is not how antitrust law does work.
This Supreme Court case explicitly establishes that antitrust laws can be used against companies which obtain a high market share simply by anticipating future demand and responding effectively and efficiently.

This would make sense as a feature. If you subscribe to the view that competitive pressure is the source of progress, then you never want any company to actually win. Like a donkey chasing a carrot on a stick, you want companies to endlessly run towards market dominance, but never actually get there - because once they do, they stop contributing to progress.
