Trump unveils $300B refinery, challenging US refiners
Reliance-backed 'America First Refining' would be first new US facility in 50 years, potentially squeezing margins at Valero, Phillips 66 and Marathon
President Donald Trump announced plans for a $300 billion oil refinery project at the Port of Brownsville, Texas, backed by India's Reliance Industries, marking the first new refinery construction in the United States in 50 years. The 'America First Refining' project would significantly expand domestic fuel production capacity and Gulf Coast energy exports, but the announcement sent shares of existing refiners lower on concerns about intensified competition and potential margin pressure.
Valero Energy, the second-largest US refiner, slipped 0.5% to $217.02, while Marathon Petroleum declined 0.2% to $215.23. Phillips 66 fell 0.3% to $162.50. The three companies control a combined refining capacity of approximately 7 million barrels per day, representing roughly 40% of total US processing capacity.
The announcement comes at a time when US refiners have been rationalizing capacity rather than expanding it. Several major refineries are scheduled for closure or conversion in 2026, including Lyondell Basell Industries' 263,776 barrel-per-day Houston refinery and Valero's 145,000 barrel-per-day Benicia facility. Phillips 66 shuttered its Los Angeles refinery in December 2025 and converted its Rodeo plant to renewable diesel production.
Marathon Petroleum remains the largest US refiner with 13 refineries and 2.96 million barrels per day of capacity, representing 16% of the national total. Valero operates 13 US refineries with 2.2 million barrels per day, or 12% of domestic capacity, while Phillips 66 holds approximately 1.9 million barrels per day of global capacity.
Reliance Industries brings substantial refining expertise to the project through its Jamnagar refinery complex in Gujarat, India, which operates as the world's largest with approximately 1.24 million to 1.4 million barrels per day of capacity. The facility, commissioned in 1999 and expanded in 2008, processed 1.37 million barrels per day in January 2026, demonstrating 4% annual growth.
Analysts caution that the timeline for the new refinery remains uncertain, and any impact on existing refiners is likely years away. The project would need to navigate complex regulatory approvals, environmental permitting, and construction challenges that typically span 5-7 years for refinery projects of this scale. Meanwhile, existing refiners continue to benefit from strong crack spreads—the difference between crude oil costs and refined product prices—as US gasoline and diesel prices remain elevated even as crude oil has plunged 30% from recent peaks.
The Brownsville location offers strategic advantages as a Gulf Coast hub with existing energy infrastructure and proximity to major crude oil production from the Permian Basin. However, the $300 billion price tag raises questions about the project's economics and return on investment given the long-term uncertainty surrounding global energy demand and the accelerating energy transition away from fossil fuels.
