Oil prices are their lowest since the pandemic, revenues are falling, and profits are shrinking, but some frackers and oilfield players are suddenly thriving in the stock market as they invest in power generation for data centers and ride the AI wave.

Liberty Energy—the fracking company cofounded by U.S. Energy Secretary Chris Wright—saw its stock jump 30% after announcing on October 17 it would more than double its planned power generation capacity for data centers. Halliburton’s stock is up about 15% this month since revealing its 20% ownership stake in VoltaGrid and its plans to partner on powering data centers worldwide. Other major oilfield players such as Baker Hughes, industry leader SLB, and Solaris Energy Infrastructure are investing big in the data center power rush as well.

“The demand for power and for AI is like nothing I’ve ever seen in terms of demand growth,” said Halliburton chairman and CEO Jeff Miller during an Oct. 21 earnings call. “We also know that, not only in the U.S., but around the world [AI] is a really big opportunity set for the same level of growth.”

The AI power push from some drillers and fracking companies comes as they face the double whammy of weak oil prices and years of declining activity because of increased efficiency from drilling rigs and hydraulic fracturing, or frac, fleets.

U.S. oil production is at an all-time high of 13.6 million barrels per day—although it’s believed to have plateaued—even though the number of frac fleets required in the U.S. dipped more than 50% in six years as larger wells were completed more quickly. For AI, most companies are using on-site natural gas generator sets or modestly sized gas-fired turbines.

Tom Curran, energy technology analyst with Seaport Research Partners, told Fortune the power opportunity is an emerging bright spot in an industry suffering through a slump.

“It’s very real, it’s early, and it’s to be determined which sort of approaches and types of contracts prove to be the most competitive,” Curran said. “Investors are still ascending the learning curve and trying to get comfortable with the risk-reward profiles of this new niche that’s arisen.”

Somewhat surprisingly, the biggest complaint of Liberty CEO Ron Gusek was directed at the boss of his former boss—President Trump—especially on the steel and aluminum needed for power equipment.

“The secretary of energy (former Liberty CEO Chris Wright) has called the race for AI dominance our next Manhattan Project,” Gusek said in his Oct. 17 earnings call. “Winning this race requires access to massive amounts of new power generation capacity and associated hardware, along with many other sophisticated components. Much of this is currently made overseas, and much of it is now subject to tariffs.”

“Is this a path to winning a race the administration has identified as so critical to our nation’s future? I would argue, no. It’s a path to mediocrity at best. I hope we quickly pivot to a different course, one that puts us firmly on the path to energy and AI dominance here in the U.S.”

Varying approaches to catch the AI bump

Liberty Energy already had invested big in natural gas generator equipment to electrify and power its fracking services in the oilfield, and now it’s adapting the digiPower technology for data centers. Fortunately, the timing fits well with the overall industry trend of electrifying the oilfield and transitioning away from dirtier diesel power.

Liberty is increasing its power generation capacity from a planned 400 megawatts to more than 1 gigawatt—enough to power about 750,000 homes—through 2027. Further increases are anticipated to meet the growing demand, Gusek said.

“My expectation is we probably end up with a higher percentage of our capacity with data center customers than maybe we had anticipated at the outset of our foray into this business,” he said. “We are confident in the growth trajectory of our power business and are expanding our power deliveries in anticipation of customer conversions from our expansive pipeline of opportunities.”

Liberty and Halliburton—partnered with VoltaGrid—are both leaning on versions of reciprocating natural gas generator sets lined up one after another at data centers. VoltaGrid just announced a deal with Oracle to deliver 2.3 gigawatts of power for data centers.

Whether the on-site power is a short or long-term solution for hyperscalers, Liberty has an answer. Liberty also partnered with nuclear power startup Oklo for companies to transition to Oklo’s small modular nuclear reactors in five years, once they’re ready to come online.

Halliburton, with its larger global footprint, including in the oil-dependent and tech-hungry Middle East, aims to take its power partnership worldwide on a “global industrial scale,” as CEO Miller described it on a recent call with analysts.

A Halliburton employee monitors a series of heavy duty pressure pumps for liquid carbon dioxide at a natural gas fracking site in 2007 in southeastern New Mexico.

Other oilfield players, such as Baker Hughes, SLB, and Solaris, are focused on increasing gas turbine manufacturing for data centers. Solaris is working with xAI at its Memphis, Tenn., complex. SLB is growing its “data center solutions” business focused on cooling systems and other critical hardware.

The key to long-term success, Seaport Research’s Curran said, is not just speed but consistency.

“It’s one thing to go out and put together the capex and plow it into building a fleet of these assets and deliver them, set them up, and turn them on; it’s another thing to meet the standards of 24-7 power reliability,” Curran said.

Gloomier current realities

While the power opportunities are bright, the current earnings reports are much more dour as the oil sector slogs along with weakened activity.

Liberty posted third-quarter net income of $43 million, down 42% year on year, while quarterly revenues fell 17%.

Likewise, Halliburton’s net income plunged down to a barely profitable $18 million—including hefty impairment charges—from $571 million, although revenues only fell 2%.

“Oil and gas industry frac activity has now fallen below levels required to sustain North American oil production,” Gusek said. “Oil producers, which comprise a vast majority of North American frac activity, opted to moderate completions against the backdrop of macroeconomic uncertainty and after exceeding production targets during the first half of the year.”

The companies are lowering their 2026 capex plans, retiring equipment, cutting jobs, and doing as much belt tightening as they can.

There is growing optimism that the global oil glut—exacerbated by ongoing OPEC production hikes—will peak in the first half of 2026, allowing for the industry to rebound in the back half of next year, CEOs said.

Curran sees that sentiment as bullish, even if it means several more months of a downturn.

“We’re finally reaching the end of what has been this long, remarkable, continued increase in U.S. oil production while we’ve had an ongoing contraction in U.S. oilfield activity,” Curran said. “That’s been because of this really miraculous continued upturn in productivity. Well, that finally seems to be reaching its end. That means, even if they want to hold oil production flat, they’re going to have to start picking up activity next year.”
