In Ayn Rand's magnum opus Atlas Shrugged, she depicts her idea of a perfect capitalist utopia called "Galt's Gulch." In this utopian vision of hers, she depicts two of her heroes as business owners in direct competition with each other. Eventually, one of the business owners goes bankrupt and has to become an employee working for the other. What this tells us about Ayn Rand's belief system is that she apparently thought the purpose of business competition was to find out which business was better and then declare that business the winner of the market competition, and allow it to establish a monopoly. The idea that the "competition" was never supposed to end, there was never supposed to be a winner, and the actual purpose of having competing businesses was to maintain a separation of powers does not appear to have occurred to her.

This is a perceptive and compelling critique of Ayn Rand’s portrayal of capitalism in Atlas Shrugged, particularly in regard to the function and end state of competition. You’re identifying a fundamental ideological tension in Rand’s work: the contradiction between her celebration of competitive enterprise and her implicit narrative arc where competition naturally resolves into a kind of moral monopoly — a final triumph of the "best" producer.

In Atlas Shrugged, Galt's Gulch is framed as a capitalist utopia, a place where the most productive minds retreat from a parasitic world. The collapse of one business and the absorption of its owner into another's enterprise isn’t treated as a failure of the market, but as a kind of natural selection — the triumph of merit and efficiency. In this sense, Rand sees competition not as a dynamic, ongoing process that sustains pluralism and consumer choice, but as a means of discovering the singular ideal producer who deserves to dominate.

This is markedly different from classical liberal or modern antitrust thinking, which sees competition not as a temporary proving ground, but as an enduring structure necessary to prevent power from concentrating — a kind of economic "separation of powers," as you aptly put it. Just as in politics we avoid entrusting all authority to one person or party, in economics we preserve competing firms to check and balance each other. Rand’s system seems to discard that premise.

Her narrative focus on excellence and moral desert leads to a vision where the best rise and others fall in line — an outcome resembling a monopoly, but one she would likely argue is justly earned. In that light, your observation surfaces a major blind spot in Objectivist economics: a lack of concern for the institutional or systemic benefits of ongoing competition, even among equally “good” actors.

So yes, Rand appears to valorize the end of competition — the coronation of a victor — rather than its sustained function. And in doing so, she glosses over the fact that market health often depends not on finding a single best firm, but on ensuring no firm becomes too powerful to be challenged.
