Project Hail Mary does not have an official streaming date yet, but the best current estimate is early to mid-June 2026 on Prime Video , with some outlets projecting late May to August 2026 depending on how long it stays in theaters.

What’s known

  • The film was released in theaters on March 20, 2026.
  • It’s an Amazon MGM title, so streaming is expected to be on Prime Video.
  • Typical estimates from recent coverage put the theatrical-to-streaming wait at about 3 months.

Best estimate

If you want the shortest practical answer: expect streaming around June 2026, possibly as early as the first half of the month.

Why the date may shift

The movie’s digital and streaming timing will likely depend on its box-office performance and how long Amazon MGM keeps it in theaters. Strong theatrical performance could push streaming later, while a quicker PVOD rollout could bring it to rental/purchase earlier in May 2026.
