NEW YORK, April 26, 2026, 13:04 EDT
- Constellation Energy showed up among the corporate bonds Donald Trump picked up in March, according to his latest financial disclosure. The filings only provide value ranges, not precise dollar figures.
- Constellation is turning to its nuclear, gas, and geothermal fleet to meet surging data-center power needs following the close of its Calpine acquisition, according to the latest disclosure.
- CEG finished Friday at $313.53, gaining around 7.1%. Market cap hovered close to $98 billion.
Constellation Energy landed back in focus after U.S. President Donald Trump’s newest financial disclosure listed the Baltimore-based power producer among the corporate bond issuers he snapped up in March. Investors are tracking the company closely these days, with its AI-fueled electricity business under the microscope.
Documents from the U.S. Office of Government Ethics listed 175 transactions, but details only specified value ranges rather than exact figures. Reuters’ math puts Trump’s bond purchases in March at no less than $51 million, with the total stretching to a possible $161 million when tallying every asset class.
This has suddenly become significant: Constellation now ranks among the most closely tracked U.S. power companies. The Calpine deal wrapped up in January, vaulting the company—by its own account—into the top spot nationwide for electricity generation. Capacity stands at 55 gigawatts, spanning nuclear, gas, geothermal, hydro, wind, solar and batteries.
The company keeps its message simple: data centers can’t afford to wait for new lines or plants—steady power is non-negotiable. When the Calpine acquisition wrapped, Constellation CEO Joe Dominguez declared the company was “stepping up to power America’s growth” as energy demand takes off. Constellation
Constellation finished Friday at $313.53, climbing roughly 7.1% for the session. After the close, a weekend disclosure brought its debt load back into focus. It’s worth noting the listing concerned corporate bonds rather than common stock—so it doesn’t offer a direct signal about appetite for CEG shares.
Policy winds appear to be shifting in Constellation’s direction. The U.S. Department of Energy has launched UPRISE, a program targeting 5 gigawatts of new nuclear capacity by 2029. That includes “uprates,” the industry’s own label for squeezing out more output from reactors already online. According to Reuters Events, Constellation stands to gain, along with rivals Vistra and Duke Energy. Reuters
“Uprates are the most cost effective and immediate way to boost nuclear capacity,” said Rian Bahran, deputy assistant secretary for nuclear reactors at the DOE, speaking to Reuters Events. James Richards at the Nuclear Innovation Alliance described the 5-gigawatt goal as ambitious—though not out of reach. Reuters
Crane Clean Energy Center—formerly Three Mile Island—is still Constellation’s main showcase. The company aims to have a reactor back online at the Pennsylvania site by late 2027, supplying power to Microsoft’s data centers. “We continue to expect to start this unit in 2027,” Dominguez reiterated to investors in March.

The outlook is anything but straightforward. PJM Interconnection, which runs the regional grid, says the location might not hook up to the power system before 2031. Constellation has also flagged in a regulatory filing that lagging transmission upgrades could jeopardize Crane’s capacity right up through late 2030. No U.S. nuclear plant that’s been completely shut down has ever started up again.
Rivalry in the sector is ratcheting up. Vistra is stepping in to provide Meta with nuclear energy, and other big power firms are hustling to lock in data-center deals by repurposing plants and leveraging grid rights. Constellation, for its part, picked up flexible gas-fired assets with the Calpine deal—faster to ramp than nuclear—but the acquisition also meant regulatory divestitures and extra complications.
Constellation’s first-quarter results are set for May 11, giving investors their next real look under the hood. For now? Just a slim update and a bigger question hanging out there: Can Constellation actually lock in deals quickly enough—leveraging nuclear tightness, government backing, and surging demand from Big Tech—to back up the stock’s surge?
