YouTube doesn’t currently show overall MAUs across the board; rather, it reports more than a Billion daily views on connected TVs and over 70 Billion daily Shorts views.
Until the beginning of 2023, YouTube said it had over 2 Billion registered users, so I can only assume they have crossed the 3 Billion mark, and the numbers are pretty similar to those of Facebook.
