Answer: The abundance of cationic molecular ions is due to the ability to stabilize unpaired electrons which makes the formation of cationic molecular ions energetically less demanding. And the most favorable reason behind the abundance of cationic molecular ions is that the cosmic ray has so much energy, it is almost unaffected by the relatively small energy required to ionize molecules. With the broadband source like the Sun, there is plenty of radiation to pump the molecules to high energy states from which they can be stimulated and spontaneous emission. That's why cationic molecular ions are most abundant than anionic ones.

Example:

Due to the low temperature and low density of interstellar space H3+ cationic molecular ion is most abundant. This H3+ is also considered as a cause of cationic molecular ions most abundant since its two electrons are only valence electrons in the system.

The other reason behind the abundance of cationic molecular ions is due to the ability to stabilize unpaired electrons which makes the formation of cationic molecular ions energetically less demanding.
