For some numbers:

The Artemis program has an estimated cost of 93B since 2012 [0].

As a comparison:

"Between 2020 and 2024, $771 billion in Pentagon contracts went to just five firms: Lockheed Martin ($313 billion), RTX (formerly Raytheon, $145 billion), Boeing ($115 billion), General Dynamics ($116 billion), and Northrop Grumman ($81 billion). In comparison, the total diplomacy, development, and humanitarian aid budget, excluding military aid, was $356 billion."[1]
