Trump Sets 12.5% Royalty for First "Big Beautiful Gulf" Oil Auction
The Trump administration has released full financial terms for its first “Big Beautiful Gulf” offshore oil and gas auction, setting a 12.5% royalty rate and offering nearly 80 million acres across the Gulf of Mexico, according to a new release from the U.S. Department of the Interior on Monday.
The details mark the first concrete pricing framework under the One Big Beautiful Bill Act, following the August announcement of a decades-long offshore leasing calendar that included at least 30 Gulf sales and six in Alaska’s Cook Inlet.
The December 10 auction, officially named Big Beautiful Gulf 1, will be the first held under the administration’s revived leasing plan and is designed to restore long-term investment certainty for offshore producers.
The DoI’s Bureau of Ocean Energy Management said the sale will cover roughly 14,000 tracts in federal waters between 3 and 231 miles offshore, with minimum bids set at $25 per acre. It marks the largest Gulf offering in nearly a decade. The 12.5% royalty, which is lower than the 18.75% rate used in recent years, is intended to stimulate bidding and accelerate project approvals after several under-subscribed auctions during the previous administration.

The new terms signal a clear push to lock in exploration spending before the next presidential cycle. Major operators including Chevron, Shell, and BP have already expanded Gulf capital budgets amid expectations of regulatory continuity. Deepwater projects account for about 15% of U.S. crude output, and twice-yearly sales give companies the predictability needed for multi-billion-dollar developments.
BOEM’s final notice confirms that most of the 14,000 tracts offered span shallow to ultra-deep waters, including areas near Shell’s Whale and Chevron’s Anchor projects in the Gulf’s Alaminos Canyon and Green Canyon blocks. Cook Inlet, meanwhile, is smaller but politically potent. Six planned sales through 2032 represent a reversal from Biden-era restrictions and reinforce Alaska’s role as both an energy hub and an Arctic gateway.
BOEM said the 12.5% royalty rate was set to encourage stronger participation by lowering upfront costs for operators after several under-subscribed auctions in prior years. The American Petroleum Institute called the move “a competitive step” that could revive investment in deepwater exploration. Reuters reported that Gulf producers see the fixed leasing calendar as critical for long-cycle projects requiring predictable federal terms.
