They didn't.
The whole point of Robber Baron was to consume the marketplace for a commodity like Tea or Steel or Cotton with control that allowed high profits through price-setting control. Robber Barons popped up in unlikely places- newspapers -Hearst; Steel -Carnegie, Mellon, Oil-Rockefeller (Standard Oil) and so on. They attracted competition infrequently, but those who sought to compete wanted a share of the baron's profits, and once established became baron's in their own right.
That was the competition they attracted; even in commerce today, the big guy's attract competition, Walmart attracts Target, Kohl's, Price Club and so on. Best Buy attracts Gregg's; General Motors attracts...everybody.
The danger in being Number 1 (with a bullet) is that someone is always taking a "shot" at you. That's why Comcast fights so hard to keep competitive Content providers and internet Service competitors from accessing it's network, as do others.
Unfortunately there are many different monopolies at work in U.S. commerce today; some subtle, and some not so subtle.
Geographic monopolies, product and service monopolies, all exist today in some degree in Health, Education, even Government.
robber barrons eliminated competition by buying them out.
John W Mackay was the opposite of a Robber Baron. He brought competition to the telegraph industry and reduced the price of telegraphs. He treated his workers fairly. The Robber Barons established cartels and cheated their workers. They ran sweat shops. They kept prices unnecessarily high. They destroyed competition.

The robber barons utilized and manipulated the idea of trusts and decimated even the smallest competition, making their industry into a monopoly. This eventually led to the Sherman-Antitrust Act.
