Elon Musk, the CEO of SpaceX, used the company’s first earnings call since its public listing to describe plans for building factories on the moon. Even he admitted the ambition sounded "totally nuts." But while Musk’s timelines often drift from reality, he is far from the only one eyeing the lunar surface. A new report from advisory firm Deloitte, provided to Fortune ahead of its Wednesday release, offers a financial framework for what could become a $566 billion lunar economy—with ripple effects that could more than double that figure to $1.1 trillion.

The report, titled “Building the Lunar Economy,” estimates the moon-based economy could generate between $343 billion and $566 billion in upside through 2050. The range reflects a conservative to accelerated-growth scenario, hinging on how fast infrastructure, energy, and transportation services become operational on the moon, and how quickly commercial businesses follow. The most optimistic projections depend on the advancement of several cutting-edge technologies, including rocket fuel derived from water ice at the lunar poles, extraction of helium-3 for cooling quantum computers, and AI data centers placed in orbit around the moon.

Despite the high barriers for non-aerospace companies, new players are entering the field. Luxury fashion house Prada applied its textile expertise to design spacesuits capable of withstanding extreme temperatures. Sunglasses brand Oakley developed a gold-plated visor for astronauts that works in both darkness and direct sunlight. The report notes: “What was once the domain of governments and a handful of aerospace contractors now includes venture-backed startups, investors, defense firms, and some of the world’s largest companies all seeking a role in the emerging lunar economy. Although still in its earliest stages, the upside potential could be massive.”

The research draws on interviews with founders, engineers, investors, and government officials, along with more than 400 model inputs. It maps out the necessary infrastructure for lunar operations—transportation, energy, communications, surface mobility, and life support—and considers the unpredictable innovations that could emerge when humanity ventures into this new domain.

Brett Loubert, who leads Deloitte’s space practice and co-authored the report, said momentum intensified last year, which also marked a record for venture capital investment in space technology. According to Seraphim’s space tracker report, $7.5 billion was invested in the second quarter of 2026, with trailing twelve-month investment reaching an all-time high of $23 billion. “What you’re seeing generally is excitement in and outside the industry for what is an explosion of data sources and services that are being delivered from orbit and beyond,” Loubert said.

A major catalyst is SpaceX itself. The company went public on June 12 with a record-setting IPO that pushed its valuation to $2 trillion, though it has since slipped to $1.8 trillion. Musk, who controls the majority of SpaceX, has a talent for generating interest from retail and institutional investors. Before the IPO, headlines focused on interplanetary Mars missions and Musk’s goal of a million-person colony. But during the first earnings call, the conversation shifted to the moon—a strategic threshold, investors say, that must be crossed before Mars becomes viable.

SpaceX has invested over $15 billion in its Starship rocket, designed to carry up to 100 metric tons to orbit. On the earnings call, President Gwynne Shotwell outlined near-term milestones: an Artemis III docking in 2027 and “boots on the moon in 2028.” Former SpaceX employees have also launched their own ventures; Forbes reports 141 such companies collectively valued at $10.6 billion. An analysis of publicly disclosed equity rounds by space companies from August 2025 to July 2026 found 47 deals with a median round size of $40 million and an average of $116.2 million, according to New Market Pitch. Spacecraft manufacturers raised $2.3 billion in 26 deals, representing 43% of the capital.

Musk continues to fuel the sector with his boosterism, moving SpaceX’s internal projection for hitting $1 trillion in revenue forward from 2031 to 2030, much of it tied to the company’s AI business. The Deloitte report’s high-growth scenario splits into two value pools. The first, “core lunar activity,” covers foundational infrastructure essential for anything else to happen. Getting to and from the moon, transportation, energy, and dealing with the jagged surface regolith account for $206 billion of the $566 billion total. Power adds another $44 billion. Communications, surface mobility, construction, and life support make up the rest of the first pool, estimated at $282 billion through 2050.

The second pool, “enabled activity,” describes downstream markets that could unlock $284 billion because of the infrastructure from the first pool. Under the accelerated-growth scenario, new resources and materials could grow to $114.5 billion, driven by rocket propellant from lunar water ice and helium-3. The report values in-space production at $105.9 billion. Fuel extraction is a major challenge: a kilogram of rocket fuel costs $1 on Earth, $4,000 in low Earth orbit, and $36,000 on the lunar surface if launched from home. But water ice in lunar soil can be processed into liquid oxygen and hydrogen, usable as rocket fuel. Economist Jim Zukin told Deloitte, “Water ice is the oil of the moon.” The report adds: “If unlocked at scale, it could do for space what gas stations did for the road: reduce the cost of existing trips, and make entirely new ones possible.”

While lunar propellant is far from scaling, compute is moving faster. Google announced Project Suncatcher, placing satellite clusters in orbit for computing. Nvidia-backed Starcloud launched a satellite last year with an H100 chip that trained an AI model in orbit. SpaceX has asked the FCC for permission to launch 1 million satellites to support space data centers. The thinking is that orbital data centers can bypass ground-level issues like community opposition. “Data-processing satellites benefit from space’s unique conditions, offering near-continuous access to solar energy and radiative cooling,” the report states. “However, the challenge is scale.”

Beyond core and enabled activities, there is innovation spillover, human inspiration, and the value of research that could unlock opportunities not yet imagined. Co-author Raquel Buscaino, who leads Deloitte’s Novel & Exponential Technologies team, said the unimagined cascade effect could add $541 billion, though Deloitte chose not to include it in the final estimate to avoid overstatement. Combined with the high-growth scenario, this pushes the lunar economy above $1.1 trillion, albeit with significant uncertainty. Buscaino noted that uncertainty is a feature, not a flaw, in space. “There is extraordinary possibility and it’s also extraordinarily hard to do those things,” she said. “Some of these distant opportunities could have extremely large upsides, and we don’t know which ones will pan out, or if what will ultimately matter the most could be a market that we haven’t imagined yet.”
