The best publicly cited number I found is that the earlier Fable Legends project reportedly cost about $75 million , but I did not find a verified public figure for the current Fable reboot budget itself.

What’s known

  • The current reboot has been delayed to February 23, 2027 on Xbox and Game Pass.
  • Recent coverage focuses on the delay and release timing, not a confirmed development cost.
  • A lot of the “how much is it costing Microsoft?” chatter online seems to be speculation rather than a disclosed budget.

Bottom line

If you mean the new Fable reboot , Microsoft has not publicly confirmed the cost, at least in the sources I found. If you mean the older cancelled project Fable Legends , the commonly cited figure is $75 million.
