John Hess led Hess Corporation, the oil-and-gas company his father Leon Hess founded as Amerada Hess, serving as chairman and CEO from 1995. Under his leadership Hess assembled one of the industry's most valuable growth portfolios, anchored by a major stake in the giant Stabroek oil block off Guyana, the largest oil discovery of the last decade, and a leading position in the Bakken shale.
In 2023 Hess agreed to a roughly $53 billion all-stock takeover by Chevron, a deal that turned on Hess's prized Guyana asset. The merger was held up for more than a year by an arbitration fight with ExxonMobil, which claimed a right of first refusal over the Guyana stake. An arbitration panel ruled against Exxon in mid-2025, and Chevron closed the acquisition on July 18, 2025.
As part of the deal, John Hess was expected to join Chevron's board, but the Federal Trade Commission initially barred him over concerns about his past communications with OPEC officials. After the FTC lifted that restriction in 2025, Hess took a seat on Chevron's board, extending his influence into one of the world's largest oil majors.

The Chevron-Hess deal triggered a high-stakes arbitration with ExxonMobil over rights to Guyana's Stabroek block, highlighting how a handful of companies control one of the world's most important new oil frontiers.

Why this matters
The Chevron-Hess deal concentrated control of one of the century's biggest oil discoveries in even fewer hands, shaping global oil supply and the energy future of Guyana, a small nation now reliant on a few oil majors. The FTC's concern over Hess's OPEC contacts shows how the conduct of top oil executives can affect the prices people pay at the pump, making the consolidation and governance of the oil industry a direct public interest.
