Competition record
Marathon Petroleum
Deep profile · 1 linked library matter
Marathon Petroleum refines and sells gasoline. It is a named station defendant in the June 2026 California Kalibrate case, which is still at the pleadings.
Overview
Marathon Petroleum is a large U.S. refiner with a branded retail network. Refining concentration is an older policy debate. The 2026 allegation is narrower: use of a shared retail pricing tool.
The company is a defendant in the Kalibrate complaint filed June 22, 2026. Being named is not a finding. The case had not produced an order by October 11, 2026.
Wholesale rack prices and street prices are different markets. This complaint is about the street.
Competition footprint
A refiner can own stations, franchise them, or both. The complaint treats branded retail pricing as the conduct.
No ruling is recorded.
Pipeline and refining mergers are outside this docket.
Consumer & business angle
Drivers buy the fuel. Dealers operate many of the stations.
Independent stations are the comparison the plaintiffs say was coordinated away.
What to watch
- Pleadings in the Kalibrate case.
- Any order that separates refiners from franchise dealers.
