big cos.

Fourteen businesses with global or regional headquarters in the Houston area appear on Fortune’s new list of the world’s 500 biggest companies.

Oil and gas company Saudi Aramco, whose headquarters for the Americas is in Houston, leads the Houston-area pack. With annual revenue of $494.9 billion, it lands at No. 4 on the Fortune Global 500. Ahead of Saudi Aramco are U.S. retailers Walmart and Amazon, and Chinese electric company State Grid.

To put Saudi Aramco’s annual revenue in perspective, the total is slightly above the gross domestic product for the Philippines.

For the third year in a row, Saudi Aramco stands out as the most profitable member of the Fortune Global 500. The company racked up $121 billion in profit last year.

Overall, Saudi Aramco and 32 other petroleum refiners — many of them with a significant presence in the Houston area — made the Fortune Global 500.

“The Global 500 is the ultimate scorecard for business success. The aggregate revenue of the Fortune Global 500 in 2023 reached $41 trillion, a record level. That sum represents more than a third of global GDP — a sign of how much economic power is concentrated in these companies,” Scott DeCarlo, Fortune’s vice president of research, says in a news release.

Here’s the rundown of Fortune Global 500 companies with global or regional headquarters in the Houston area, including the ranking and annual revenue for each:

  • Saudi Aramco, No. 4, $494.9 billion, Americas headquarters in Houston
  • ExxonMobil, No. 12, $344.6 billion, global headquarters in Spring

Following years of speculation, Chevron announces HQ move to Houston

big news

The Energy Capital of the World is adding another jewel to its corporate crown.

With the impending move of Chevron’s headquarters from Northern California to Houston, the Houston area will be home to 24 Fortune 500 companies. Chevron ranks 15th on this year’s Fortune 500.

Oil and gas giant Chevron, currently based in San Ramon, California, will join three Fortune 500 competitors that already maintain headquarters in the Houston area:

  • Spring-based ExxonMobil, No. 7 on the Fortune 500
  • Houston-based Phillips 66, No. 26 on the Fortune 500
  • Houston-based ConocoPhillips, No. 68 on the Fortune 500

Chevron, which posted revenue of $200.9 billion in 2023, employs about 7,000 people in the Houston area and about 2,000 people in San Ramon. The company says its chairman and CEO, Mike Wirth, and vice chairman, Mark Nelson, will move to Houston before the end of 2024.

In an interview with The Wall Street Journal, Wirth acknowledged Chevron’s differences of opinion with California policymakers regarding energy matters.

“We believe California has a number of policies that raise costs, that hurt consumers, that discourage investment and ultimately we think that’s not good for the economy in California and for consumers,” Wirth said.

Chevron expects all of its corporate functions to shift to Houston over the next five years. Jobs that support the company’s California operations will remain in San Ramon, where Chevron employs about 2,000 people. Some Chevron employees in San Ramon will relocate to Houston.

The company’s move to Houston hardly comes as a surprise. Speculation about a relocation to Houston intensified after Chevron sold its 98-acre San Ramon headquarters in 2022 and moved corporate employees to leased office space. Over the past several years, Chevron has shifted various corporate functions to Houston.

“This is just the final step that many industry observers were waiting to happen,” Ken Medlock, senior director of the Baker Institute’s Center for Energy Studies at Rice University, says in a news release.

“To start, Houston provides a world-class location for internationally focused energy companies, which is why there is such a massive international presence here,” Medlock adds. “Texas is also the nation’s largest energy producer across multiple energy sources and is poised to lead in emerging opportunities such as hydrogen and carbon capture, so Houston is a great place for domestically focused activities as well.”

The announcement of Chevron’s exit from California comes just a year after ExxonMobil finalized its relocation from Irving to Spring.

“Chevron’s decision to relocate its headquarters underscores the compelling advantages that position Houston as the prime destination for leading energy companies today and for the future,” Steve Kean, president and CEO of the Greater Houston Partnership, says in a post on the organization’s website.

“With deep roots in our region,” he adds, “Chevron is [a] key player in establishing Houston as a global energy leader. This move will further enhance those efforts.”

Chevron eyes $7B Texas power plant for Microsoft data center campus

power deal

Software giant Microsoft is negotiating exclusively with Houston-based oil and gas titan Chevron and investment firm Engine No. 1 about the development of a $7 billion power plant in West Texas that would supply electricity for a Microsoft data center campus.

The proposed natural-gas-fired plant initially would generate 2,500 megawatts of electricity, Bloomberg reports. The plant would be built near Pecos, a Permian Basin city, in an area where Microsoft plans to build a 2,500-megawatt data center campus on a 7,000-acre site.

A deal with Microsoft would secure a long-term customer for the plant’s output and help finance its construction, Bloomberg says. The project, expected to be producing power by 2030, still requires tax and environmental approvals as well an agreement to terms among Chevron, Engine No. 1, and Microsoft.

In a statement issued after Bloomberg reported the news, Chevron acknowledged it was in exclusive talks with Engine No. 1 and Microsoft, but the oil and gas company offered no details.

Chevron says the proposed plant “reflects an emerging shift in how power for AI is being developed, bringing energy supply closer to demand through co-located, behind-the-meter generation to deliver reliability while helping avoid added strain on regional electricity systems. It pairs sustained, always-on demand from advanced computing with proven capability to design, build, and operate large-scale energy infrastructure.”

Development of gas-powered electrical plants for AI data centers represents a new—and potentially lucrative— business line for Chevron. In 2025, Chevron, Engine No. 1 and GE Vernova announced a partnership to produce natural gas for AI data centers in the U.S.

Chevron’s collaboration with Engine No. 1 has already secured an order for seven large natural gas turbines from GE Vernova, according to Bloomberg.

“Energy is the key to America’s AI dominance,” Chris James, founder and chief investment officer of Engine No. 1, said last year. “By using abundant domestic natural gas to generate electricity directly connected to data centers, we can secure AI leadership, drive productivity gains across our economy, and restore America’s standing as an industrial superpower.”

8 CERAWeek 2026 takeaways from a new Houston energy leader

guest column

My first CERAWeek was a blur.

Having top energy executives, policymakers, and technologists all gathered in Houston—over 11,000 of them this year—was both overwhelming and energizing. The theme was “Convergence and Competition: Energy, Technology, and Geopolitics,” and walking through the George R. Brown Convention Center, it was immediately clear that this was no ordinary industry conference.

As a first-timer with a Greentown Labs lens, here’s what really stuck with me.

Disruption is the new normal

CERAWeek 2026 was set against the backdrop of conflict in the Middle East, the continued race to power AI, and a clear throughline: disruption is increasingly the new normal. You could feel it in every hallway conversation. The ongoing conflict in the Middle East, specifically Iran’s attacks on Qatar’s Ras Laffan facility and the closure of the Strait of Hormuz, affected roughly 20% of the world’s liquified natural gas supply, and that was woven into nearly every conversation throughout the week.

Secretary of Energy Chris Wright opened the conference with “Energy is life,” then quickly turned to natural gas. “America’s superpower is natural gas,” he said, pointing to its role in industry, heat, electricity, fertilizer, exports, and leading AI and manufacturing. That set the tone early and it never really shifted.

AI is still everywhere, but the conversation has shifted

No surprise that AI dominated the agenda. But what struck me as a first-timer was how much the conversation had matured. The AI discussion has moved from general enthusiasm to a much more practical focus on real use cases and measurable outcomes.

NVIDIA, Anthropic, and CyrusOne joined the established tech presences of Microsoft, Google, and AWS, occupying the Innovation Agora’s new AI Hub, which displaced the hydrogen hub from prior years. That detail alone tells you something about where the energy conversation has shifted. Annual global investment in data centers reached $771 billion in 2025, nearly on par with oil and gas ($835 billion) and renewable energy ($798 billion). We are not talking about a niche technology story anymore. This is a capital story, an infrastructure story, and an energy story all at once.

The prevailing tone was uncertain; the gap between what is being announced and what can actually be delivered was the subtext of almost every conversation. Transmission takes over a decade to build. The new generation takes five to nine years. AI infrastructure moves on three-to-five-year timelines. The math doesn’t work yet, and everyone is aware.

Pitch competitions still draw crowds

The Energy Venture Day and Pitch Competition at the McKinney Balcony was one of my favorite events of the week. Seeing Greentown members on that stage never gets old, but what really energized me was the broader mix: students, new founders, and veteran entrepreneurs in one space, all talking about how what they’re building is going to impact the world. S&P Global launched the NextGen cohort with 100+ graduate students from around the country getting a front-row seat to the energy sector.

Geothermal may have stolen the show

If I had to pick the most surprising theme of my first CERAWeek, it was geothermal. It drew the most consistent endorsement of the week, with Department of Energy representatives, oil and gas majors, and operators broadly aligned on its potential. Project InnerSpace hosted a dedicated Geothermal House for the first time, launching a standardized resource classification framework with the Society of Petroleum Engineers and an XPRIZE collaboration targeting surface-plant supply chain breakthroughs. For a sector that has lived in the shadows of wind and solar for years, CERAWeek 2026 was geothermal’s time to shine.

Wow, was I impressed with Melanie Nakagawa

Melanie Nakagawa, chief sustainability officer at Microsoft, delivered an impressive keynote during her fireside chat with Brad Burke. Her depth of experience, from the U.S. Department of State and venture capital to her current role at Microsoft, was matched only by her calm, hopeful demeanor. Leaders like her at the helm of climate action inspire genuine confidence in the future.

What about hydrogen?

Hydrogen was notably absent from the main stage. The AI Hub in the Innovation Agora displaced the hydrogen hub that had been a fixture in prior years. Seems like hydrogen still plays a role, but not as quickly or broadly as hoped. Blue hydrogen is moving forward cautiously. It wasn’t gone from the conversation entirely, but it no longer commands the room.

The label problem isn’t going away

Politics continues to polarize the industry. Climatetech, sustainability, cleantech — some labels carry broad objectives, others have become tribal signals. “Energy transition” for some means a replacement of fossil fuels; for others, it means an evolution across multiple dimensions simultaneously. CERAWeek 2026 showed an industry increasingly focused not on feel-good narratives about the future of energy, but on the harder questions of security, buildout, reliability, affordability, and competitiveness. A pragmatic shift may be the best answer to the label problem.

Collaboration isn’t optional—it’s strategic

The energy transition is no longer primarily an environmental story. It has become a technology and national competitiveness story. The problems are too big for any one company, sector, or country to solve alone. From incubators and investors to utilities and hyperscalers, the message was consistent all week: move together or we don’t move. S&P Global introduced “The Bridge,” a new venue specifically for energy-tech crossover conversations: a small but meaningful signal that even the conference organizers recognize that collaboration will get us further.

The scale and the energy in the room (pun intended) are what stood out most from my first CERAWeek. The industry knows what needs to get built. The question now is whether we can work together to build it fast enough.

See you next year, CERAWeek.
