The Interstellar Stock Exchange (ISE) is opened when any civilization builds the first planetary stock exchange. Once opened, major civilizations can buy Galactic Monetary Fund shares, paving the way for an economic victory to be possible.
Economic victory occurs when your empire's Gross Domestic Product (GDP) corresponds to a large percentage of the Gross Galactic Product (GGP), and your empire holds a large percentage of shares of the Galactic Monetary Fund (GMF), for for 10 consecutive turns. The percent required for victory is dependent on the number of races active in the game:
| Civilizations | Threshold |
|---|---|
| 2 | 50% |
| 3 | 48% |
| 4 | 46% |
| 5 | 44% |
| 6 | 42% |
| 7 | 40% |
| 8 | 38% |
| 9+ | 30% |
