Sean “Diddy” Combs has been in jail since his arrest in September 2024, so by January 2026 he has been locked up for around 1 year and a few months (about 16 months).

Quick timeline

  • He was arrested and taken into custody in September 2024, and has remained behind bars since then.
  • In October 2025, he was sentenced to 50 months (just over 4 years) in prison on federal charges related to transporting people across state lines for sexual encounters.
  • That 50‑month sentence gives him credit for about 13 months he had already served before and during the trial.

How long has he been in jail vs. how long will he stay?

As of early 2026:

  • Time already served: About 13–16 months, depending on the exact date you count from in September 2024.
  • Total sentence: 50 months in prison (about 4 years and 2 months).
  • Projected release: Federal prison records and news reports put his expected release around mid‑2028, after factoring in time served and credit for good behavior, though that can change if he violates prison rules.

So in simple terms for “how long has Diddy been in jail”: a bit over a year so far, with a total sentence that runs for roughly four years from his original detention.
