The Final Frontier of Real Estate: Commercial Lunar Land Claims Emerge by 2026

Commercial interest in the Moon has moved from science fiction to signed contracts, with companies racing to stake out extraction sites on a celestial body that no nation can legally own.

For centuries, the Moon was the province of poets and astronomers. Then, for a brief twelve years between 1969 and 1972, it was the province of twelve American men in pressure suits. Since then, it has drifted back into abstraction. But in 2026, the Moon is becoming something else entirely: a prospective address for commercial operations, with companies negotiating delivery contracts for lunar-extracted materials and 64 nations establishing the diplomatic framework to make extraction legal. The question of who owns what on the Moon is no longer theoretical. It is the central legal argument of the next decade.

A Treaty Written for a Different Age

The foundation of lunar law was laid in January 1967, when the United States, the Soviet Union, and the United Kingdom opened the Outer Space Treaty for signature. Written at the height of the Cold War and ratified by what are now 118 nations, the treaty established a foundational principle: no country can claim sovereignty over the Moon or any other celestial body. The Moon, in the language of the treaty, belongs to all humankind.

What the drafters of the 1967 treaty did not anticipate was the emergence of private commercial actors with the capital, technology, and legal creativity to exploit resources without technically claiming territory. The analogy that space law scholars now routinely deploy is maritime fishing: no nation owns the high seas, but fleets own the fish they catch. By the 2010s, the United States had embraced this interpretation explicitly. The 2015 Commercial Space Launch Competitiveness Act granted American citizens the right to own, transport, use, and sell any resources extracted from asteroids or the Moon while formally disclaiming any intent to claim sovereignty over the celestial body itself.

Luxembourg enacted its own version in 2017. The United Arab Emirates followed in 2019. Japan passed legislation in 2021. Brazil did so in 2024. Italy joined the club in June 2025. By mid-2025, six nations had enacted domestic laws permitting space resource extraction, each taking the position that mining a celestial body does not constitute appropriating it.

The Accords as the New Property Deed

The Artemis Accords, first signed in October 2020 by eight nations and drafted jointly by NASA and the U.S. Department of State, attempted to elevate the American interpretation of the Outer Space Treaty into an internationally accepted norm. Section 10 of the accords states explicitly that signatories affirm resource extraction does not constitute national appropriation. Section 11 introduces "safety zones" around active operations to prevent what the accords describe as "harmful interference" from other actors.

By April 29, 2026, Morocco became the 64th nation to sign on, completing a remarkable expansion from eight founding members in six years. The accords now include 29 European signatories, 16 in Asia, seven in South America, five in North America, five in Africa, and two in Oceania. The coalition has grown to include countries building emerging space capabilities alongside countries that joined primarily to secure a future role in lunar cooperation.

Critics have not been quiet. Legal scholars have argued that the accords circumvent the UN treaty process, allowing the U.S. to shape international norms through a coalition of the willing rather than through multilateral negotiation. China has been more direct: state-affiliated Chinese media have likened the Artemis Accords to "European colonial enclosure land-taking methods." Russia, consumed by the Ukraine conflict and watching its own space program deteriorate, chose a different path by partnering with China on the rival International Lunar Research Station initiative.

The safety zones provision has become the sharpest flashpoint. Proponents argue these zones are practical operational necessities, protecting sensitive equipment from rocket exhaust and debris. Critics note that granting a single actor exclusive use of a defined area of the lunar surface is, in practical effect, what sovereignty has always looked like.

The First Commercial Invoice from the Moon

On May 7, 2025, Interlune, a Seattle-based natural resources company, announced the most consequential commercial transaction in the history of lunar exploration. The U.S. Department of Energy's Isotope Program had agreed to purchase three liters of helium-3 harvested from the Moon's surface for delivery on Earth no later than April 2029. The price was set at approximately the current commercial market rate, which Interlune pegs at roughly $20 million per kilogram, making helium-3 among the most expensive substances on Earth.

The DOE agreement marked the first government purchase of a non-terrestrial natural resource. The deal also sent a signal to investors: the U.S. government had formally acknowledged, with a purchase order, that lunar resource extraction was a real business.

Interlune was founded in 2020 by Rob Meyerson, formerly the president of Blue Origin, and Gary Lai, Blue Origin's former chief architect, alongside Apollo 17 astronaut Harrison "Jack" Schmitt, one of the few living people to have walked on the Moon. Schmitt had been advocating for lunar helium-3 extraction since 1986, when physicist Gerald Kulcinski at the University of Wisconsin-Madison recruited him for a research project on fusion fuel. The company name itself is derived from a 1994 research proposal Schmitt helped draft for NASA, titled "Interlune-One."

The commercial pipeline Interlune has built extends well beyond the DOE. Maybell Quantum Industries contracted to purchase thousands of liters of helium-3 for annual delivery between 2029 and 2035, intended to fuel quantum refrigeration systems. Bluefors, the Finnish cryogenic cooling company that serves the quantum technology industry, signed an agreement in September 2025 to purchase up to 10,000 liters annually from 2028 through 2037. The logic of these contracts is straightforward: helium-3 is scarce on Earth because the planet's magnetosphere deflects the solar wind that deposits it. The Moon has no such protection and has been accumulating the isotope for billions of years.

To extract the three liters committed to the DOE, Interlune will need to process enough lunar regolith to fill a large backyard swimming pool. That quantity of material cannot be transported back to Earth for processing; it must be refined on-site. In May 2025, Interlune unveiled a full-scale prototype of its lunar excavator, built in partnership with Vermeer Corporation, the industrial equipment manufacturer. The machine is designed to process 100 metric tons of regolith per hour in continuous motion.

The South Pole and the Coming Congestion Problem

Helium-3 is not the only prize driving the commercial land rush. The Moon's south pole is widely understood to be the most valuable address in the inner solar system. Permanently shadowed craters near the pole are believed to contain substantial deposits of water ice, which can be split into hydrogen and oxygen for rocket propellant and life support. Any actor capable of manufacturing propellant on the lunar surface would command a decisive logistical advantage over missions forced to carry all their fuel from Earth.

The problem is that the permanently shadowed regions containing the most resource-rich ice deposits occupy a constrained physical area. Multiple nations and companies are targeting the same small zones under legal frameworks that do not agree with each other. NASA awarded Intuitive Machines a $180.4 million contract in March 2026 for its IM-5 mission to Mons Malapert near the south pole, targeting a ridge with continuous Earth visibility and access to the shadowed craters. China's Chang'e 7, scheduled for late 2026, is also aimed at the south pole. ispace, the Japanese commercial lunar company, received a commitment of up to 20 billion yen from Japan's Space Strategy Fund in January 2026 to develop precision landing technology near the same region.

The Artemis Accords' safety zones offer one mechanism for managing this competition, but China and Russia, operating under the rival International Lunar Research Station framework, are not bound by those rules. The ILRS has attracted partners including Pakistan, Egypt, South Africa, and Venezuela, creating a distinct legal and operational bloc with different expectations about resource rights, data sharing, and interference prevention. As geopolitical analysts have noted, if the two blocs operate under conflicting definitions of safety zones, accidental interference on the lunar surface could escalate into conflict back on Earth.

From Registry to Reality

The legal architecture being built around lunar property rights is intricate, layered, and deliberately incomplete. Frans von der Dunk, a space law scholar at the University of Nebraska-Lincoln, has argued that the Artemis Accords strengthen the U.S. interpretation of the Outer Space Treaty, namely that individual states have the right to allow private sector engagement in commercial space activities. The opposing interpretation holds that unilateral commercial exploitation is incompatible with the treaty and that only an international licensing regime could legitimize it.

Both interpretations will soon face a practical test. Interlune's roadmap calls for a demonstration mission in 2027 and a pilot plant operational by 2029. Blue Origin, Firefly Aerospace, Intuitive Machines, and Astrobotic are all planning lunar lander missions before the end of 2026. A fifth and sixth decade of Artemis signatory nations have joined in the first four months of 2026 alone. The pace of accession suggests the diplomatic framework is maturing faster than the legal disputes that surround it.

What is certain is that the Moon's status as an unclaimed commons, undisturbed for the half-century since Apollo 17, is ending. The land may still belong to everyone. But the operations beginning to take root on it, the extraction sites, the safety zones, the delivery contracts with Earth-based customers, carry the operational logic of ownership whether or not any treaty officially says so. Harrison Schmitt walked on the Moon in December 1972, collected samples from the surface, and spent the next five decades arguing that what he had seen there was worth going back for. In 2025, the U.S. government agreed enough to write a purchase order.
