How did Stephenson 2/18 get so big?

Stephenson 2-18 is a red supergiant. It would have started as a very massive main sequence star, and become a supergiant after the end of core hydrogen burning. During shell burning, stars expand as they blow off gases into the envelope. This expansion creates red giants.

What is the largest known star?
