The U.S. has spent about $24 billion to $25 billion so far on Golden Dome, depending on the source and whether you count “allocated” or “provided” funding. That money was approved in last year’s legislation, while the Pentagon later raised its broader cost estimate to $185 billion for the full system.

What that means

  • Already approved: about $24 billion to $25 billion.
  • Current Pentagon estimate: $185 billion over the program’s planned buildout.
  • Higher outside estimates: some analysts and the Congressional Budget Office have put the total much higher, including a CBO estimate around $542 billion and one later report estimating $1.2 trillion over two decades.

Quick context

Reuters reported in January 2026 that the program had made little visible progress and had not yet used a significant share of the money already allocated. Foreign Policy also reported in February 2026 that as much as $14 billion in Golden Dome-related space funding was still pending approval from the Office of Management and Budget.
