ExxonMobil

Exxon Mobil Corporation (ExxonMobil) is the largest US-headquartered oil and natural-gas company by revenue and market capitalization, with approximately $340 billion in annual revenue across its Upstream (oil and gas exploration and production), Energy Products (refining), Chemical Products, and Specialty Products segments. The company traces its origins to Standard Oil Company (founded 1870 by John D. Rockefeller) and emerged in its current form from the 1999 merger of Exxon and Mobil. ExxonMobil trades on NYSE as XOM with a market capitalization of approximately $520 billion as of 2026 — making it one of the largest publicly-traded companies in the world by market value. The company employs approximately 62,000 workers globally with major operations in the US, Guyana (the most consequential recent oil discovery), Qatar, the UAE, and across Africa and Latin America.

ExxonMobil's 2024 acquisition of Pioneer Natural Resources (~$60 billion) significantly increased the company's Permian Basin shale position, making ExxonMobil the largest Permian producer by volume. The company's Low Carbon Solutions business (announced 2021) has invested heavily in carbon capture and storage (CCS), hydrogen, and biofuels — the Baytown, Texas low-carbon hydrogen complex announced in 2023 will be one of the largest hydrogen production facilities in the world.

ExxonMobil has been an AI-leader within the oil-and-gas industry for decades, with extensive in-house ML applications across reservoir modeling, seismic interpretation, drilling optimization, and operations monitoring. The company's partnerships with Schlumberger DELFI, Halliburton iEnergy, and Baker Hughes Leucipa span the broader oilfield-services AI ecosystem. ExxonMobil has been a leader in methane-emissions monitoring AI — the company's deployment of Bridger Photonics aerial methane-detection technology and partnership with the Methane Emissions Reduction Program span tens of thousands of well sites. Direct Air Capture AI (deployed at the Houston Ship Channel CCS hub project) increasingly uses ML for capture-system optimization. The Low Carbon Solutions division has invested in AI-augmented hydrogen-electrolyzer optimization and biofuels-production AI. Going forward, ExxonMobil's AI strategic focus is split between extending traditional upstream-and-downstream AI applications and building the AI capability for the energy-transition portfolio.
