SpaceX Secures $40 Billion GPU Lease With Apollo Global
SpaceX and Apollo Global Management agree to a $40 billion master finance lease for NVIDIA Vera Rubin GPUs.
Space Exploration Technologies Corp. (SpaceX) has secured a $40 billion master finance lease with an entity managed by Apollo Global Management to acquire NVIDIA’s next-generation Vera Rubin graphics processing units (GPUs).
Announced in a joint press release on October 26, 2026, the agreement stands as the largest committed GPU financing on record. The hardware will be deployed across terrestrial data centers selected by SpaceX to power its Grok artificial intelligence models and expand its cloud services footprint.
Structuring the record-breaking lease
The binding commitment letter, signed on October 24, 2026, outlines a master finance lease rather than traditional corporate debt. Under this structure, the Apollo-managed entity will retain ownership of the hardware and lease it to SpaceX. The transaction is expected to close before the end of 2026, subject to specified closing conditions.
According to a Form 8-K filed with the U.S. Securities and Exchange Commission (SEC), each lease schedule will carry an expected term of five to 5.25 years from its commencement date. SpaceX will pay one-twentieth of the financed cost of the respective tranche quarterly in advance.
The financing was led by Apollo and Goldman Sachs, with the latter serving as the sole structuring agent. Anchor commitments were provided by funds and accounts managed by BlackRock, Goldman Sachs Asset Management, and KKR.
SpaceX Chief Financial Officer Bret Johnsen stated that the company is seeing payback periods of less than one year on its Super Intelligence infrastructure investments.
“This lease diversifies our funding sources and addresses a notable portion of the funding required to deliver on our growth plans as we aim to get additional compute online at record speeds to power Grok for enterprises and consumers, as well as serve existing and future cloud services customers,” Johnsen said.
From aerospace to artificial intelligence
The $40 billion hardware acquisition accelerates SpaceX’s aggressive expansion into terrestrial computing, a strategic shift that began when the aerospace manufacturer absorbed artificial intelligence company xAI in an all-stock deal on February 2, 2026.
Since the acquisition, SpaceX has been building massive data centers, including the Colossus facilities in Memphis, Tennessee, to support its generative AI models. The NVIDIA Vera Rubin GPUs, which represent the chipmaker’s next-generation architecture, will be delivered in tranches. Lease schedules are expected to commence in the first half of 2027 upon delivery of the equipment.
The financing agreement follows a period of significant corporate restructuring for SpaceX. The company’s shares began publicly trading following an initial public offering on June 12, 2026. On October 20, 2026, SpaceX and Tesla announced the formation of special committees to explore a potential merger that would combine Tesla’s electric vehicle and robotics businesses with SpaceX’s aerospace, satellite internet, and AI operations.
AirPro News analysis
This $40 billion lease highlights a critical evolution in how massive artificial intelligence infrastructure is funded. By utilizing an equipment lease rather than issuing corporate bonds or equity, SpaceX is leveraging the underlying value of the NVIDIA hardware itself. As SpaceX Founder and Chief Executive Officer Elon Musk recently noted, debt markets have largely closed to “neocloud” providers that lack substantial independent revenue. SpaceX was able to secure this record-breaking financing due to its investment-grade credit rating and the strong, established revenue streams generated by its Starlink satellite internet constellation and commercial launch operations.
The scale of this investment also underscores SpaceX’s transformation from a pure-play aerospace manufacturer and launch provider into a diversified technology conglomerate. While the company continues to manufacture the Falcon 9, Falcon Heavy, and Starship launch vehicles, its capital expenditures are increasingly directed toward terrestrial data centers and compute power, positioning it to compete directly with established hyperscale cloud providers.

NASA Restructures Artemis Program, Targets 2028 Moon Landing
NASA redefines Artemis III as a 2027 LEO demo and targets 2028 for the first crewed lunar landing with SpaceX or Blue Origin.
The National Aeronautics and Space Administration (NASA) has fundamentally restructured its Artemis program, redefining the Artemis III mission as a low Earth orbit demonstration in 2027 and pushing the first crewed lunar landing to 2028. The agency has also unassigned specific landers for the initial landing missions, creating a direct competition between its two commercial providers based on hardware readiness.
In a press release issued on October 23, 2026, NASA announced it has updated the concepts of operations for its commercial human landing system (HLS) providers, Space Exploration Technologies Corp. (SpaceX) and Blue Origin. The realignment is designed to accelerate lander development and mitigate technical risks as the agency prepares to establish a long-term presence at the Lunar South Pole.
Redefining Artemis III and the race to 2028
Under the original Artemis architecture, SpaceX was assigned to provide the lander for the Artemis III and IV missions, while Blue Origin was contracted for Artemis V. The October 23 announcement dissolves those specific assignments. Both providers will now participate in the redefined Artemis III mission, which will launch in 2027 to demonstrate rendezvous and docking capabilities between test versions of the commercial landers and the Orion spacecraft in low Earth orbit (LEO).
The first crewed lunar landing is now targeted for 2028. NASA will select either SpaceX or Blue Origin for this initial landing based on which company demonstrates lander readiness first, with a second crewed landing opportunity to follow for the other provider. During these initial surface missions, two crew members will descend to the lunar surface for two approximately two-hour-long moonwalks, while two astronauts remain aboard the Orion spacecraft.
NASA Administrator Jared Isaacman emphasized the agency’s aggressive new posture regarding the timeline.
“We have a proven foundation in SLS and Orion, along with two lunar landers in development with Blue Origin and SpaceX. But NASA has no intention of sitting idly by as all the pieces come together. That is not how Apollo succeeded, and it is not how the near-impossible is achieved. NASA is energized, our core capabilities are being rebuilt, our machine shops are running 24/7, and our experts are in the field attacking the critical path. We are building a Super Bowl-caliber team to safely achieve these objectives and everything that comes next.”
Updated concepts of operations for SpaceX and Blue Origin
To meet the 2028 target, both commercial providers have significantly altered their mission architectures. SpaceX has updated its concept of operations for the Starship HLS. The new plan involves launching multiple tanker Starships to LEO to transfer cryogenic propellant to a depot Starship, which will then fuel the Starship lander. The lander will rendezvous and dock with the Orion spacecraft in Earth orbit and perform a trans-lunar injection burn to send the combined stack to low lunar orbit. To facilitate this, NASA is modifying the Orion spacecraft to enable Starship to push it to the Moon. SpaceX is also adding two demonstrations of its crew cabin to reduce risk.
Blue Origin has taken a different approach with its Blue Moon Mark 2 Alpha Lander. The company is deferring propellant transfer entirely for the initial missions. Instead, Blue Origin will use three transfer stages to send the lander to the Moon, operating similarly to a multistage rocket. The combined stack will depart for an elliptical polar orbit around the Moon. According to NASA, this orbital path reduces propellant requirements and maximizes the performance of the Space Launch System (SLS) rocket compared to the previously planned near-rectilinear halo orbit. Blue Origin is also adding new human-in-the-loop testing and hardware readiness milestones.
Jeremy Parsons, NASA’s Artemis program manager, stated that updating the contracts ensures the agency and its partners are aligned on requirements and milestones. He noted that NASA and the lunar lander providers have been working closely to ensure the return of American astronauts to the Moon by 2028.
The commercial human landing system program history
The HLS program utilizes a public-private partnership model with firm-fixed-price, milestone-based contracts, a departure from traditional cost-plus government procurement. NASA awarded the initial $2.89 billion HLS contract to SpaceX in April 2021. Two years later, in May 2023, the agency selected Blue Origin as the second Artemis lunar lander provider under a $3.4 billion contract.
The push to accelerate development follows a period of programmatic reassessment. In March 2026, NASA hosted “Ignition Day,” announcing architecture updates that initiated the realignment of the HLS contracts. That same month, a report from the NASA Office of Inspector General (OIG) highlighted that while the fixed-price approach effectively controlled costs, both SpaceX and Blue Origin faced schedule delays, technical difficulties, and integration challenges. These findings prompted NASA to work directly with the companies to streamline designs and accelerate development to secure the 2028 landing date.
AirPro News analysis
The decision to unassign specific missions from SpaceX and Blue Origin represents a major shift in NASA’s procurement and operational strategy. By effectively pitting the two aerospace manufacturers against each other in a race to flight readiness, NASA is leveraging commercial competition to mitigate the schedule delays identified by the OIG earlier this year. Moving the Artemis III docking demonstration to low Earth orbit removes the immediate pressure of a lunar landing while still validating critical rendezvous hardware.
The technical changes are equally significant. Modifying the Orion spacecraft to be pushed by the Starship lander indicates a deeper integration of commercial hardware into the core Artemis architecture, blurring the lines between government-owned and commercially operated vehicles. Meanwhile, Blue Origin’s shift to a multistage transfer approach and an elliptical polar orbit demonstrates a willingness to bypass complex in-orbit propellant transfer requirements in favor of more traditional, albeit heavy-lift dependent, orbital mechanics to meet the 2028 deadline.

BAE Systems Acquires Colorado Facility for Space Hardware
BAE Systems buys a 130,000-sq-ft facility in Weld County, Colorado, backed by nearly $20M in tax incentives for space hardware production.
BAE Systems has acquired a 130,000-square-foot production facility in Weld County, Colorado, to scale up its domestic manufacturing capacity for space-based hardware, software-defined radios, and sensor systems.
The property purchase, announced in a company press release on October 21, 2026, marks a major infrastructure investment for the defense contractor’s Space & Mission Systems division. The expansion is supported by nearly $20 million in state and federal tax incentives, reflecting a broader governmental push to secure domestic supply chains for critical aerospace technologies.
Facility details and economic incentives
Located at 4120 Specialty Place in unincorporated Weld County near Firestone, the new facility sits on a 13-acre campus. BAE Systems plans to spend the remainder of 2026 and all of 2027 retrofitting the building and procuring specialized manufacturing equipment. Production operations are anticipated to commence in early 2028.
The project advanced with substantial financial backing from the state of Colorado. The Colorado Economic Development Commission (EDC) approved a performance-based Job Growth Incentive Tax Credit valued at up to $11,184,835 over an eight-year period. The company also secured up to $8.6 million in CHIPS Refundable Tax Credits. Both incentive packages are contingent upon the company meeting specific net new job creation and salary requirements.
BAE Systems expects to hire more than 200 new employees over the next 12 to 24 months to staff the facility. At full operational capacity, the site could accommodate up to 600 workers.
“We look forward to expanding our production capabilities in Colorado with our first facility in Weld County. The support we received from the Weld County Commissioners and the State of Colorado played a key role in our ability to locate this essential production work for the company in Colorado, extending our manufacturing presence in the state,” said Alexis Wang, Vice President of Operations for BAE Systems.
Local and state officials highlighted the economic impact of the aerospace sector in the region. Colorado Governor Jared Polis noted that the investment will bring hundreds of jobs to Weld County, solidifying the state as a hub for advanced manufacturing. Scott James, Chair of the Weld County Board of Commissioners, stated that projects of this scale strengthen the entire industry ecosystem and create new opportunities across the region.
Integrating the Ball Aerospace acquisition
The Weld County expansion is a direct continuation of BAE Systems’ strategy to grow its footprint in the space sector, a push that accelerated significantly in early 2024. In February 2024, the company completed its $5.6 billion acquisition of Ball Aerospace, which formed the core of its newly established Space & Mission Systems division.
The new Firestone location joins an established network of Colorado production facilities inherited and expanded through the Ball Aerospace deal, including sites in Boulder, Broomfield, and Westminster. During the state regulatory and EDC review process in June 2026, the expansion project was shielded under the codenames “Project Mercury” and “Project Sodium” before the official site selection was made public.
Meeting Department of Defense space requirements
The physical expansion in Colorado aligns with an increased operational tempo for BAE Systems in securing United States Space Force and Department of Defense (DoD) contracts. The military is currently driving a rapid transition toward resilient satellite architectures, advanced missile warning systems, and secure communications networks, requiring contractors to scale up their hardware production capabilities.
In October 2026, Space Systems Command selected BAE Systems to design and demonstrate jam-resistant radio frequency terminals for a space-based data layer. This program relies heavily on the type of software-defined radios that the new Weld County facility is slated to produce.
This follows another major milestone in September 2026, when the company completed the critical design review for the U.S. Space Force’s Resilient Missile Warning and Tracking Medium Earth Orbit (MEO) Epoch 2 program.
The Colorado site purchase is part of a wider domestic manufacturing investment strategy by the company. In May 2026, BAE Systems announced a $135 million self-funded investment to upgrade its manufacturing sites in Hudson, New Hampshire, and Austin, Texas, aimed at speeding the delivery of critical systems for U.S. military readiness.
AirPro News analysis
We view the Weld County facility acquisition as a clear indicator of how rapidly BAE Systems is moving to capitalize on its $5.6 billion purchase of Ball Aerospace. By establishing a dedicated, high-capacity manufacturing center for space hardware, the company is positioning itself to transition from research and development contracts into full-scale production for the U.S. Space Force’s proliferated satellite architectures.
The successful application of CHIPS Refundable Tax Credits for this facility is equally notable. It demonstrates the growing overlap between semiconductor manufacturing incentives and national security space programs. As the Department of Defense demands more secure, domestically produced microelectronics and software-defined radios for orbital assets, defense contractors that can leverage federal and state industrial policy funds will hold a distinct capital advantage in scaling their production lines.
