No—not through an ordinary, treaty-supported private land purchase. Antarctica’s territorial claims are held by states, and the Antarctic Treaty preserves those states’ positions without resolving them. It also bars new or enlarged claims while the Treaty is in force and says activity during that period creates no sovereignty rights. That is different from a specific treaty clause expressly prohibiting every conceivable private transaction: the Treaty addresses state sovereignty, and the official sources do not identify a private Antarctic title registry.
What “buying land” would mean in Antarctica
A land purchase normally transfers a legally recognized title that identifies the owner and the rights attached to a parcel. Antarctica presents a different situation: several states maintain territorial claims, some of which overlap, while other states do not recognize those claims. The United States and Russia maintain a “basis of claim.” Article IV of the Antarctic Treaty protects these differing positions without settling them.
The Treaty’s rule is about sovereignty, not a detailed system for private conveyancing. It does not establish a normal process by which an individual can purchase a parcel and obtain generally recognized sovereign title. Nor do the official sources reviewed identify a private Antarctic land-title registry. So a listing, certificate, or purported deed should not be mistaken for an ordinary, treaty-supported property right.
What Article IV says about territorial claims
Article IV preserves the positions of states with existing claims or bases of claim. It also prevents activity during the Treaty’s operation from creating sovereignty rights. The Treaty states: “No acts or activities taking place while the present Treaty is in force shall constitute a basis for asserting, supporting or denying a claim to territorial sovereignty in Antarctica or create any rights of sovereignty in Antarctica.” It further provides: “No new claim, or enlargement of an existing claim, to territorial sovereignty in Antarctica shall be asserted while the present Treaty is in force.” Read the Antarctic Treaty and its Article IV framework.

Seven countries maintain territorial claims: Argentina, Australia, Chile, France, New Zealand, Norway, and the United Kingdom. Some claims overlap. Article IV does not decide which claim should prevail, and the existence of a state claim is not equivalent to a private person holding title.
Why 2048 does not mean Antarctica goes up for sale
The Antarctic Treaty and the Environmental Protocol do not have an automatic termination date. The year 2048 marks a procedural possibility under the Protocol: from then, a Consultative Party may request a conference to review how the Protocol operates. It does not trigger expiration or open a land market. Any amendment would have to follow the Protocol’s procedures, and changing the mineral-resource prohibition has additional conditions. The Secretariat explains the Environmental Protocol and its review mechanism.

Not owning land does not by itself answer whether someone may travel to Antarctica, conduct research, build a facility, or undertake another activity. The Protocol calls Antarctica a “natural reserve, devoted to peace and science” and requires environmental considerations to guide activity. It prohibits mineral-resource activity other than scientific research. These are rules about protection and activity, not a standalone private-property clause.
Treaty parties implement environmental obligations through domestic laws and authorize activities by their citizens and organizations. Requirements depend on the relevant national authority and the proposed activity. For example, Australian citizens, residents, and organizations—including private expeditions—must seek environmental approval for proposed Antarctic activity. Australia also says entering an Antarctic Specially Protected Area without a specific permit is an offence under its implementing legislation. Those examples illustrate regulated access; they are not a complete permitting guide for every nationality. See the Australian Antarctic Division’s environmental approval requirements and its overview of Antarctic environmental legislation.
Quick Recap
Rank #4
Three distinctions to keep straight
- State claims versus private title: states maintain territorial claims or bases of claim; that does not create an ordinary private purchase route.
- Ownership versus activity: permission to visit, research, or build is a separate question from owning land.
- Treaty rules versus domestic permits: the Treaty system sets shared obligations, while national authorities apply domestic requirements to people and organizations under their jurisdiction.
