Here's How Much You'd Have If You Invested $1000 in Marathon Petroleum a Decade Ago
Read MoreHide Full Article
For most investors, how much a stock's price changes over time is important. Not only can it impact your investment portfolio, but it can also help you compare investment results across sectors and industries.
FOMO, or the fear of missing out, also plays a role in investing, particularly with tech giants and popular consumer-facing stocks.
What if you'd invested in Marathon Petroleum (MPC - Free Report) ten years ago? It may not have been easy to hold on to MPC for all that time, but if you did, how much would your investment be worth today?
Marathon Petroleum's Business In-Depth
With that in mind, let's take a look at Marathon Petroleum's main business drivers.
Findlay, OH-based Marathon Petroleum Corporation is a leading independent refiner, transporter and marketer of petroleum products. The company, in its current form, came into existence following the 2011 spin-off of Houston, TX-based Marathon Oil Corporation’s refining/sales business into a separate, independent and publicly traded entity. In October 2018, Marathon Petroleum completed the acquisition of its rival Andeavor in a $23.3 billion deal, thereby becoming the nationwide largest refining company by market capitalization. The deal also made the company the largest U.S. refiner and the fifth largest in the world by capacity.
Marathon Petroleum operates in three segments: Refining and Marketing, Midstream and Renewable Diesel.
Refining and Marketing (R&M): The unit’s operations include 13 refineries, located in the West Coast, Gulf Coast and the Mid-Continent regions of the United States, having a combined crude processing capacity of about 3 million barrels per day. Additionally, Marathon Petroleum – through its marketing organization – sells transportation fuels, asphalt and specialty products throughout the country to support commercial, industrial and retail operations. In the fourth quarter of 2025, the Refining & Marketing segment recorded adjusted EBITDA of $2 billion.
Midstream: This unit is operated primarily through MPLX and it gathers, transports, stores and distributes crude oil, refined products and renewable diesel using pipelines, terminals, marine vessels and refining logistics assets. It also gathers, treats and processes natural gas and handles natural gas liquids (NGL) transportation, fractionation, storage and marketing. The business is advancing MPLX’s integrated wellhead-to-water strategy to support growing U.S. energy demand. The Midstream segment reported adjusted EBITDA of $1.7 billion in the fourth quarter of 2025.
Renewable Diesel: In the fourth quarter of 2024, Marathon Petroleum launched this segment, separating these activities and assets from the Refining & Marketing segment. The unit reported adjusted EBITDA of $7 million in the fourth quarter of 2025.
In 2021, Marathon Petroleum sold its Speedway business to Japanese retail group 7-Eleven, Inc., a wholly owned subsidiary of Seven & i Holdings Co., Ltd.– for $21 billion.
Bottom Line
Anyone can invest, but building a successful investment portfolio takes a combination of a few things: research, patience, and a little bit of risk. So, if you had invested in Marathon Petroleum a decade ago, you're probably feeling pretty good about your investment today.
According to our calculations, a $1000 investment made in September 2016 would be worth $9,673.54, or a gain of 867.35%, as of September 18, 2026, and this return excludes dividends but includes price increases.
The S&P 500 rose 257.04% and the price of gold increased 216.79% over the same time frame in comparison.
Analysts are anticipating more upside for MPC.
Marathon Petroleum benefits from the scale and integration of a large, diversified U.S. refining system and a logistics network that enhances crude sourcing, product placement and regional optimization. Its majority ownership of MPLX provides durable fee-based midstream cash flow and diversifies earnings beyond refining. A favorable refining environment, elevated global capacity outages and tight U.S. fuel inventories are supporting margins. Advantaged crude access also enables feedstock optimization and reduces exposure to costly crude dislocations. Meanwhile, investments in jet fuel, specialty gasoline and diesel yields should strengthen the product mix. Export flexibility adds further growth potential by allowing MPC to capitalize on domestic and international markets. These strengths support an Outperform Recommendation.
Over the past four weeks, shares have rallied 17.79%, and there have been 6 higher earnings estimate revisions in the past two months for fiscal 2026 compared to none lower. The consensus estimate has moved up as well.
