Territory? Either Paraterraformed Arctic/Antarctic, desert, or ocean based.
The Antarctic is not only part of one state, but of multiple states (with a lot of nice border disputes to come - because the claims are overlapping) . Even the UK claims a significant share of Antarctica. In the Arctic is race is already opened. The main players are: The US (in this case in a strategical alliance with the EU) versus Canada - and all three together versus Russia.

To found a state you need to establish three main criteria:
1) A territory
2) The possibility to exercise the typical powers invested in states (iure imperium)
2) Subjects - euphemistic called people
Unfortunately for you: There is no territory worldwide on which no state has a claim. In some cases even more than one state.
