Reply to comment by TomSurman in Ultramassive black hole over 30 billion times mass of our sun has been spotted. The discovery had been made possible thanks to a phenomenon known as gravitational lensing — the first time a black hole has been spotted in such a way. by Wagamaga

I’m pretty sure we found a bigger one not too long ago

Wikipedia lists two bigger ones, but says the data is unreliable. Their estimated masses are greater than the theoretical maximum a black hole should have been able to reach in a universe this young.
