Trump claimed about 150,000 people attended, while one report said well over 100,000 spectators were on the National Mall; those are the only concrete crowd figures I found for last night’s fireworks.

What’s clear

  • Trump’s own crowd claim: 150,000.
  • A later report describing the scene: well over 100,000 people.

Why the number is fuzzy

Crowd counts for big outdoor events are often estimates, and this one was complicated by storm delays and evacuations, which makes a precise headcount unlikely.

Quick read

If you want the shortest answer: roughly 100,000 to 150,000 people were there, depending on which estimate you use.
