As of now, Betelgeuse has not yet reached the supernova stage. Despite some dramatic changes observed in recent years, including a significant dimming event in late 2019 and early 2020, and subsequent brightening, Betelgeuse is still in a late stage of its stellar life but has not exploded yet.
Recent studies indicate that Betelgeuse might be in the late stages of core carbon burning, a phase that could last around 1,000 years. While it's possible that Betelgeuse could explode within the next few decades, it might also remain stable for several hundred more years
