Are "gateways" considered mega structre?

[makaramus]

Asking because I want to access mega structres without having habitats... playing as authoratian fanatic xenophobe criminal syndicate.
I know having a mega structre in your system boost chances significantly to get tech required for mega structres. is gate way one of them?

Yes, Gateways are Megastructures. To the best of my knowledge, you do need Mega-Engineering to build them, although you DON'T need any of the Mega-Structure Ascension Perks to build them either. Of course, Master Builders helps for drawing the Mega-Engineering tech card in the first place, but its not explicitly required.

EDIT/CORRECTION/ADDENDUM: Reading the question more carefully and noting the subsequent response by sillyrobot, while my above statement is correct with respect to if the gateways are considered mega-structures in any sense, it is incorrect with respect to the original question (as sillyrobot points out, they don't help draw the megastructure tech). Keeping my original response here above this edit for reference of what was originally said.

Although gateways are megastructures, having one inside your territory does not count towards the megastructure tech bonus.

Here's the check used (from scripted_triggers.txt):

any_system_within_border = {
OR = {
has_megastructure = spy_orb_1
has_megastructure = spy_orb_2
has_megastructure = spy_orb_3
has_megastructure = spy_orb_4
has_megastructure = think_tank_1
has_megastructure = think_tank_2
has_megastructure = think_tank_3
has_megastructure = think_tank_4

well... thats sad
Thanks for information :/
its too hard to get for a tech that decide your gameplay unless you go for habitats
