Everything in the game files that lists this technology as a prerequisite; “condition” marks objects that check for it in their conditions instead.
How to get Dyson Sphere
Research in Stellaris is drawn: each area offers 3 cards at a time, weighted by each technology's draw weight (here 20) and its weight modifiers. Tier 5 opens after 6 tier 4 technologies of the same area. As a rare technology it is drawn less often, and some rare ones only appear after an event, a relic or a special project.

How do I get Dyson Sphere in Stellaris?
Research Mega-Engineering first (6 technologies in the whole chain); then Dyson Sphere can be drawn as one of the 3 physics research options. It is a rare technology: its draw weight is low, and some are only offered after an event, a relic or a special project. It also has conditions (see Requirements on this page).
What does Dyson Sphere do?
It unlocks Dyson Sphere (megastructure), Dyson Sphere Frame (megastructure), Dyson Sphere Site (megastructure), Dyson Sphere: Initial (megastructure), Dyson Sphere: Medial (megastructure) and Dyson Sphere: Penultimate (megastructure).
What is the ID of Dyson Sphere?
The technology's ID is tech_dyson_sphere. To get it with the console: research_technology tech_dyson_sphere (Stellaris 4.5.2).
How much does Dyson Sphere cost?
24,000 physics research before modifiers. In game the cost grows with empire size (+0.2% per point above the base, common/defines) and the galaxy's tech cost setting.
