Plains traces to Plains Marketing and Transportation, a crude gathering and marketing operation founded in 1985. After building through the 1990s on acquisitions of pipeline systems and terminals, Plains All American Pipeline went public on the NYSE in 1998 as an MLP, listing as one of the earlier midstream partnerships of the modern wave.

The 2000s brought aggressive pipeline M&A: Plains assembled crude systems across Texas, the Rockies, and the Midcontinent, and the 2008 acquisition of Pacific Energy Partners added West Coast pipelines. It became the dominant mover of crude into Cushing, Oklahoma, the WTI pricing hub, and built NGL fractionation and Canadian operations through deals including the 2012 acquisition of BP's Canadian NGL business.

The shale boom centered Plains on the Permian, where it built gathering and long-haul crude systems feeding Gulf Coast export and refining demand. Plains GP Holdings was created as the consolidating public entity for investors preferring corporate-style ownership of the partnership.

Recent moves reshaped the portfolio. In June 2025 Plains agreed to sell substantially all of its Canadian NGL business to Keyera for approximately C$5.15 billion, sharpening focus on crude oil, with the divestiture expected to close toward the end of the first quarter of 2026. FY2025, ended December 31, 2025, showed revenues of $44.3 billion, down from $48.9 billion on lower commodity prices and merchant volumes, but net income attributable to PAA jumped 86 percent to $1.44 billion and distributions rose 17 percent to $1.5575 per unit.

Plains' most significant public incident was the 2015 Refugio oil spill off Santa Barbara County, California, when a corroded Plains pipeline released more than 140,000 gallons of crude onto the coastline. The event produced criminal charges, a felony conviction for environmental violations, hundreds of millions in cleanup costs and settlements, and lasting scrutiny of Plains' pipeline integrity program.

Beyond Refugio, Plains faces the standard midstream regulatory environment: PHMSA safety oversight, FERC rate regulation on interstate tariffs, and environmental permitting reviews for new construction. The Canadian NGL sale reflected portfolio strategy rather than regulatory pressure.
