The most credible reporting I found does not give one exact official headcount for Trump’s speech last night, but one account says the National Mall crowd was thin and estimated turnout at more than 1,000 , while Trump himself claimed at least 45,000 people attended.

What the reports say

  • The strongest third-party estimate I found was more than 1,000 attendees.
  • Trump’s own post claimed 45,000 people were there.
  • Other coverage described a cheering crowd at the National Mall but did not provide a firm official count.

Best read on the number

Based on the available reporting, the safer answer is that attendance was likely in the low thousands, not tens of thousands.

That said, without an official event tally, any exact figure should be treated as an estimate.
