he Trump administration held the government’s first sale of oil and gas drilling rights in the Gulf of Mexico since 2023 on December 10, 2025, generating $279.4 million in high bids for 187 blocks as energy companies returned to offshore leasing under lower royalty rates.

The auction, officially named Big Beautiful Gulf 1 (BBG1), offered 81.2 million acres across the Gulf at a royalty rate of 12.5%, the lowest permitted under Trump’s new tax law. The sale marks the first of 30 lease sales mandated by the president’s One Big Beautiful Bill Act, signed into law in July 2025.

The Bidding

BP and Chevron emerged as the top bidders in the auction, with 26 companies participating and submitting 219 bids total. The Bureau of Ocean Energy Management (BOEM) accepted bids on 187 blocks after evaluating whether offers met fair market value thresholds.

The $279.4 million result represents weaker bidding compared to the last Gulf of Mexico lease sale in December 2023, which generated $372.5 million under the Biden administration. The decline comes as U.S. crude oil prices have fallen approximately 20% over the past year, potentially limiting drillers’ appetite for new investments despite technological advances in deepwater drilling.

Royalty Rate Reduction

The Trump administration reduced the royalty rate from 16.66% to 12.5% to encourage greater industry participation. Under Biden’s 2022 Inflation Reduction Act, oil companies were required to pay 16.66% royalties to the U.S. Treasury and Gulf states. The new lower rate aims to boost drilling activity and domestic fossil fuel production.

The royalty reduction comes as offshore production accounts for approximately 14-15% of domestically produced oil, with the Gulf of Mexico playing a critical role in the nation’s energy portfolio despite lagging behind onshore shale fields in recent years.

Revenue Sharing

The lease sale is the first that will generate higher revenue-sharing payments under the Gulf of Mexico Energy Security Act (GOMESA), which distributes a portion of bid prices and royalties to Louisiana, Texas, Mississippi and Alabama. However, there is typically a five-year lag between when leases are sold and when wells begin producing oil and gas that generates royalty revenue.

“We followed through on our promise to unleash American energy with the passage of our historic Working Families Tax Cut, which required lease sales in the Gulf of America,” said Majority Leader Steve Scalise, R-Jefferson, whose district represents coastal Louisiana parishes where many oil and gas support businesses are located.

Future Sales

BOEM has already proposed a second lease sale (BBG2) scheduled for March 11, 2026, which will offer approximately 15,000 unleased blocks covering roughly 80 million acres. The One Big Beautiful Bill Act requires BOEM to hold at least two lease sales per year from 2026 through 2039, plus one additional sale by March 15, 2040.

The Trump administration’s offshore leasing plans represent a significant departure from Biden’s approach, which planned for a historically small number of oil and gas auctions as part of efforts to transition away from fossil fuels and address climate change.

Industry Context

The Gulf of Mexico Outer Continental Shelf spans approximately 160 million acres and contains an estimated 29.59 billion barrels of undiscovered, technically recoverable oil and 54.84 trillion cubic feet of natural gas, according to BOEM estimates.

Offshore drilling in the Gulf typically requires longer development timelines and higher upfront capital costs compared to onshore shale operations. However, technological advances in deepwater drilling have helped maintain the Gulf’s importance to U.S. energy security, even as lower crude prices create headwinds for new investments.

Overview

The December 10 auction marks the resumption of regular Gulf of Mexico lease sales after a two-year gap, with reduced royalty rates designed to incentivize greater industry participation. While the $279 million result fell short of the previous sale’s $372 million, the Trump administration’s commitment to 30 mandated sales through 2040 signals a long-term shift toward expanded offshore drilling. The weaker bidding reflects broader market conditions, including lower oil prices and the longer timelines required for offshore projects to reach production.
