Interplanetary markets are what happens when economic activity extends beyond Earth. With SpaceX, Blue Origin, and national space programs accelerating, the frameworks for space commerce are being discussed seriously right now.

The challenges that make space economics fascinating:

Communication delay — markets rely on real-time information. Mars is 4-24 minutes away by light speed. You can’t have real-time trading between Earth and Mars. Martian economies would need to be largely autonomous — local price discovery, local supply and demand, local monetary systems.

Resource scarcity (and abundance) — water on Mars is scarce and incredibly valuable. Asteroid mining could produce more platinum than Earth’s entire supply. The resource economics of space are completely different from Earth.

Property rights — the Outer Space Treaty (1967) says no nation can claim sovereignty over celestial bodies. But companies need property rights to invest. This is one of the biggest unresolved legal questions.

Transportation costs — getting anything to Mars costs roughly $1,000-10,000 per kg. This makes local manufacturing essential and changes the entire economic structure.

Currency — what currency do you use on Mars? Earth currencies are subject to the communication delay problem. A Mars-local currency (possibly cryptocurrency-based) seems likely. See Descentralized Finance.

Governance — who regulates a Martian market? This is Political Cyclicity in action — new territories create new political structures.

The deeper question: space commerce forces us to rethink economic assumptions that seem universal but are actually just Earth-specific.
