Blackstone President and Chief Operating Officer Jon Gray has described electricity infrastructure as a way to invest in the growth of AI and other power-hungry industries. He has also named defense and life sciences as sectors reached by Blackstone’s thematic investing approach, but the available interview account does not detail specific investments or a separate thesis for either sector. The evidence is therefore strongest on electricity—and Gray presents that opportunity with meaningful risks, not as a guaranteed winner.
Why Gray sees an investment opportunity in electricity
Gray’s argument begins with rising demand for power. Data centers are one driver, but he also points to robots, autonomous vehicles and reindustrialization. If those trends continue, they will need electricity as well as the infrastructure to generate it, move it through the grid and connect users to supply.
At Blackstone’s Annual LP Meeting on May 19, 2026, Gray described the theme this way: “If you think about power and energy, that’s a pretty easy thing to believe in, which we do it in a number of ways.” That is Gray’s management view, recorded in Blackstone’s account of the meeting and published June 5, 2026—not an assurance that demand or investment returns will meet expectations. Blackstone cautions that views and trends may not come to pass and can reverse.
The areas Gray named include pipelines, utilities, renewable energy, electrical equipment and utility services. These are different parts of the energy system: some support generation or fuel transport, while others help deliver electricity or connect and maintain power infrastructure. His point is that investing in the AI buildout need not mean investing only in the data centers themselves.

What Blackstone’s demand figures do—and do not—show
Blackstone’s Fall 2025 “Powering the Future” presentation supplies market context for the thesis. It says energy and power represent a $23 trillion investment opportunity through 2040, attributing that estimate to McKinsey & Company’s “The Infrastructure Moment.” The figure is an estimate reproduced in Blackstone’s presentation; it is not a Blackstone forecast of returns, a guarantee of spending or a measure of how much capital Blackstone can invest.
The same presentation forecasts a 40% increase in U.S. electricity demand over the following decade and cites Princeton Net-Zero America (2024). This is a forecast, not observed growth. The two figures describe different things: one is an estimated investment opportunity across energy and power through 2040; the other is a forecast change in U.S. electricity demand over a decade. Neither establishes how much of the projected need will be built, which companies will benefit or whether investments will earn attractive returns.

How Gray describes Blackstone’s thematic approach
In an interview with Semafor, published August 27, 2026 and updated August 28, Gray described looking for “good neighborhoods”: markets where a broad trend may support growth and reveal adjacent opportunities. The example in the interview is data centers. Exposure to that business can give an investor a view of hyperscaler demand and related needs, such as contractors and cooling equipment.

That approach is a way of forming and extending an investment thesis, not proof that every company connected to a theme will succeed. Gray says investors have to keep testing a thesis rather than become attached to it. The distinction matters in fast-changing markets: a strong demand narrative can coexist with uncertainty about the cash flows a particular investment will produce.

What the sources establish about the three sectors
| Theme | What is established | What remains unclear |
|---|---|---|
| Electricity and supporting infrastructure | Gray has named power infrastructure categories and described electricity demand as an investment theme. Blackstone’s Fall 2025 presentation includes the attributed demand and opportunity estimates. | These sources do not establish realized returns, the probability that forecasts will materialize or which investments will benefit most. |
| Defense | Semafor reports that Gray cited defense as one sector reached by Blackstone’s thematic approach. | The interview account does not identify a specific deal, portfolio company, investment amount, performance measure or distinct defense thesis. |
| Life sciences | Semafor reports that Gray cited life sciences alongside defense as an example of a sector reached by the approach. | The interview account does not identify a specific deal, portfolio company, investment amount, performance measure or distinct life-sciences thesis. |
That difference in detail is important: electricity has a stated demand rationale and supporting market estimates in the cited material, while defense and life sciences are examples Gray named without further explanation there. The three themes should not be treated as equally documented investment cases.
Risks that could weaken the electricity thesis
Gray’s comments include several counterweights to the growth case. He acknowledges that the buildout could be overdone, that it may face political pushback, and that shortages of power and equipment can constrain construction. A demand forecast does not remove these risks: bottlenecks may slow projects, and a surge in building can still exceed what users ultimately need.
He also describes uncertainty for software and white-collar businesses as AI changes their economics; in his view, lower valuation multiples and markdowns may follow. Semafor separately reports Gray’s concern about uncertainty in the future cash flows of fast-moving AI investments. These are his assessments of possible outcomes, not established results for every business affected by AI.
Gray’s role at Blackstone
Blackstone’s 2025 Form 10-K says Gray was appointed President and Chief Operating Officer in 2018. It also identifies him as a member of the firm’s Management Committee and nearly all of its investment committees. That role provides context for his comments, but his public remarks should still be read as management views rather than independent confirmation of an investment’s prospects.
