According to TMZ, Trump is considering commuting P Diddy's sentence as early as this week:

Notably, Trump said in an August Newsmax interview that he would not pardon Diddy because was "hostile" toward him when he ran for office.
This comes after the news in July that officials claimed he was considering a pardon.
Diddy was found guilty on two counts of transportation for prostitution and sentenced to 50 months in jail. Trump claims the rapper has requested a pardon.
This market will resolve Yes if Trump takes any action in 2025 that results in any reduction of his sentence, including a full pardon.
If he is moved to a lower security prison or given preferential treatment while incarcerated but his sentence remains as-is, it will not affect the outcome of this market.
Only actions confirmed taken by Trump to reduce or eliminate his sentence will be enough to resolve Yes.
If no action is taken in 2025, this market resolves No.
