Remember this "Ton 618" at 40 BILLION solar masses. 

I just learned that the theoretical upper limit for SBH mass is about 270 BILLION solar masses!  But probably not much bigger than 50 BILLION solar masses.

"The limit is only 5×10¹⁰ M_☉ for black holes with typical properties, but can reach 2.7×10¹¹ M_☉ at maximal prograde spin (a = 1).^{[7][8][9][10]}

Thank you for your reply. I am actually not sure which are good sources, so happy to seek guidance. 

Thank you.
