Project Hail Mary is already streaming on Prime Video for subscribers, with reports confirming it arrived on Friday, July 3, 2026, at 3:01 a.m. ET.

What that means

  • If you have an active Amazon Prime membership, it should be available to watch at no extra cost now.
  • Before that, it was streaming on MGM+ first, then moved to Prime Video.
  • Some coverage also noted it as ā€œfreeā€ for Prime subscribers rather than a separate rental or purchase.

Timing

There was earlier speculation that it might not reach Prime Video for free until around mid-to-late August 2026, but that estimate was superseded by the confirmed July 3 Prime Video release.
