Alligator Alcatraz was open for 350 days, with the first detainee arriving on July 2, 2025, and the last detainee leaving on June 17, 2026. That means the average daily cost for Alligator Alcatraz was $3.4 million.
We're pleased that the court is requiring Florida to prove that Alligator Alcatraz is closing permanently -- vague assurances of 'just trust us' from Florida officials and ICE just don't cut it.
