Marathon Petroleum Corporation (MPC) is a leading U.S. downstream and midstream energy company headquartered in Findlay, Ohio. Valued at a market cap of $113.5 billion, its business centers on refining crude oil into fuels, distributing petroleum products, and operating the infrastructure that moves and stores energy.

Companies valued at $10 billion or more are typically classified as "large-cap stocks," and MPC fits the label perfectly, with its market cap exceeding this threshold, underscoring its size, influence, and dominance within the oil & gas refining & marketing industry. Its market leadership stems from its large, integrated refining system, strategic midstream assets, and disciplined capital allocation. Its refineries are connected through pipelines, terminals, and marine transportation, allowing the company to optimize crude sourcing, product flows, and regional demand.
