By urban area population - but the city itself has to be the capital
The Ruhr is included, and regardless of where exactly you measure from, it is larger than and within 500 miles of Berlin.
New Delhi is the capital of India; it is a smaller city in the urban area of India's largest city, Delhi.
Jakarta is still the capital of Indonesia at time of writing. If Nusantara becomes the capital, no city in Indonesia will appear on this list.
Yaoundé, Cameroon, is marginally more populous than Douala at time of writing.
Several cities (Reykjavik, Victoria, most Oceanian capitals) would likely be included if they had a population of 1 million, but I cannot find a reliable and complete list of cities that small. Also, not the capitals of Jetpunk countries, but Saint-Denis (Reunion) and other territorial capitals are in this category.
