No one can know the real numbers of cancellations unless Disney announces them, which will never happen.
Quarterly earnings...
183 million Disney+ and Hulu subscriptions, an increase of 2.6 million versus Q2 fiscal 2025
128 million Disney+ subscribers, an increase of 1.8 million versus Q2 fiscal 2025
But internally they monitor this metric on a day-to-day metric, people are absolutely losing their shit over the cancellation at Disney.
