Enterprise Products Partners controls more than 260 million barrels of storage capacity across the US Gulf Coast, more than any other publicly traded infrastructure company. That scale points to a pattern among oil storage stocks in 2026: the largest names by market capitalization aren’t the integrated majors dominating headlines, but midstream operators and terminal owners running long-term, fee-based contracts largely insulated from crude price swings.
How We Ranked the Top 10 Oil Storage Stocks
This list orders publicly traded companies with material crude oil, refined product, NGL, or LNG storage and terminal operations by current market capitalization. Companies where storage is incidental to a broader integrated business, the kind covered in OGSN’s largest crude oil storage companies ranking, are excluded in favor of names where storage and terminal infrastructure drives a meaningful share of revenue.
Most entries here operate as master limited partnerships, a structure the US Energy Information Administration notes typically earns fee-based revenue from long-term throughput contracts, insulating cash flow from crude and NGL price swings in a way an upstream producer’s earnings never are.
1. Enbridge, Canada
Enbridge trades on both the NYSE and TSX with a market capitalization of approximately $99 billion, the largest on this list. Its pipeline and terminal network underpins North American crude movement, anchored by the Mainline System, commonly cited as the world’s longest crude oil and liquids pipeline system. Enbridge pairs that pipeline capacity with tank farm storage at hubs including Hardisty, Alberta and Cushing, Oklahoma. That scale and a diversified revenue base spanning liquids, gas transmission, and renewables keep it the largest name among oil storage stocks heading into 2026.
2. Williams Companies, United States
Williams Companies carries a market capitalization of roughly $85 billion, built primarily on natural gas gathering, processing, and transportation rather than crude storage specifically. Its Transco pipeline system remains the largest natural gas pipeline network in the United States, moving gas from the Gulf Coast to the Northeast alongside associated NGL storage and processing capacity. Williams reported record results in the first quarter of 2026 on the strength of that gas strategy. It’s a gas-heavy name on a storage-focused list, but its scale earns it a place near the top.
3. Enterprise Products Partners, United States
Enterprise Products Partners holds a market capitalization of approximately $80 billion and controls more than 260 million barrels of storage capacity for NGLs, crude oil, refined products, and petrochemicals, the largest storage footprint of any company here. Its Gulf Coast terminal network links Permian Basin production to international buyers through major crude and NGL export facilities. As a master limited partnership, Enterprise generates most of its revenue from long-term, fee-based contracts, the clearest example of that structure on this list.
4. Energy Transfer, United States
Energy Transfer’s market capitalization sits at approximately $70 billion, supported by a network the company puts at roughly 130,000 miles of pipeline. Its Nederland Terminal on the Gulf Coast ranks among the largest crude oil and NGL export terminals in North America, giving the partnership significant staging and storage capacity ahead of seaborne exports. Its 2026 growth has leaned on expanding that export infrastructure rather than new upstream investment.
5. Kinder Morgan, United States
Kinder Morgan’s market capitalization stands at roughly $68 billion, built on an energy infrastructure network spanning approximately 83,000 miles of pipeline. Kinder Morgan’s terminals segment operates liquids storage facilities across US ports and inland hubs, handling crude oil, refined products, and chemicals under long-term throughput agreements. The company has continued expanding Gulf Coast pipeline and LNG capacity through 2026, including its Trident Pipeline project.
6. Targa Resources, United States
Targa Resources carries a market capitalization of approximately $60 billion, concentrated on natural gas liquids gathering, processing, and export tied to the Permian Basin. Its Mont Belvieu complex in Texas ranks among the largest NGL fractionation and storage hubs in the world, feeding export terminals along the Gulf Coast. It’s a narrower, NGL-focused play compared with the more diversified midstream names above it.
7. MPLX, United States
MPLX carries a market capitalization of roughly $58 billion and operates the midstream logistics network built to support Marathon Petroleum’s refining system. Its crude and refined product terminals connect Marathon’s refineries to pipeline and marine export infrastructure across the US. As a partnership majority owned by Marathon Petroleum, MPLX’s storage and logistics revenue stays largely separate from the refining margins driving its parent’s earnings.
8. Cheniere Energy, United States
Cheniere Energy’s market capitalization sits at approximately $56 billion, built entirely around liquefied natural gas rather than crude storage. Its Sabine Pass facility exports at a rate of 29.5 million tonnes per annum, the largest LNG storage and export complex in North America, with a second major terminal at Corpus Christi. Cheniere raised production guidance in the first quarter of 2026 on record export volumes.
9. Vopak, Netherlands
Vopak is the only pure-play independent tank storage company on this list, with a market capitalization of approximately €5.4 billion ($5.9 billion) on Euronext Amsterdam. The Rotterdam-based operator runs 70 terminals with combined capacity of 37 million cubic meters across roughly 25 countries, storing crude oil, refined products, chemicals, and LNG. Unlike every other name on this list, Vopak carries no upstream production, shipping fleet, or refining operations, making it arguably the truest of the oil storage stocks covered here despite its smaller market capitalization.
10. Odfjell, Norway
Odfjell rounds out this list with a market capitalization of approximately $900 million on the Oslo Stock Exchange, the smallest of the group. The company’s core business is chemical tanker shipping, but its Odfjell Terminals subsidiary operates tank storage facilities across the US, Europe, and Asia, handling chemicals and clean petroleum products. It’s a smaller, chemical-focused alternative to the crude and NGL storage names dominating the rest of this list.
The Future of Oil Storage Stocks: What to Watch in 2026
New LNG capacity from Cheniere and further Gulf Coast terminal expansion from Energy Transfer and Enterprise Products are likely to shift storage capacity figures through the rest of 2026. Odfjell has flagged further terminal investment ahead of its 2026 Capital Markets Day in Oslo, one of several smaller moves that could reorder the bottom half of this list. The fee-based contract structure underpinning most oil storage stocks means capacity additions, not crude price swings, will do most of the reordering.
Which oil storage stock has the largest market cap in 2026?
Enbridge, at approximately $99 billion. It isn’t a pure storage play, but its pipeline and terminal network gives it the largest liquids storage and transportation footprint on this list.
What criteria determines this oil storage stocks ranking?
Market capitalization among publicly traded companies with material crude oil, refined product, NGL, or LNG storage and terminal operations, current as of 2026.
What’s the difference between a storage MLP and an integrated oil major?
MLPs and midstream storage companies earn fee-based revenue from long-term throughput contracts, largely independent of crude price. Integrated majors’ earnings track commodity prices directly.
Is Vopak a pure oil storage stock?
Yes. Unlike every other name on this list, Vopak has no upstream production, shipping fleet, or refining business, its entire revenue comes from its 70 terminals and 37 million m³ of storage capacity.
What could change this ranking through 2026?
New LNG capacity from Cheniere, further Gulf Coast terminal expansion, and any material swing in NGL or crude pricing affecting MLP distribution coverage could reorder the list, particularly in the lower half.
