Black holes in general tend to rotate very fast, as they try to conserve angular momentum while shrinking in size.
The supermassive black hole at the center of our galaxy Sgr A* (4.3 million solar masses!) is spinning with an angular velocity that is ~60% of the max possible value, and with an angular momentum of ~90% of the max possible value.
Sgr A*'s spin causes the spacetime around it to be squashed down to the shape of a football.
