The streamer renewed the series in June 2023, a month after its premiere. But Davidson said he has changed his mind because he feels "this part of my life is done."
It's the latest series to be renewed and then cancelled, although the network or streamer reverses most decisions.
Now it looks like fans — spoiler alert — won't find out how Davidson fares after his car accident at the end of season one.
The series also stars Edie Falco and Joe Pesci and comes from Universal Television and Lorne Michaels' Broadway Video.
The first season had a large entourage of guest stars, including Machine Gun Kelly, Steve Buscemi, Bobby Cannavale, Charlie Day, Al Gore, Paul Walter Hauser, Chase Sui Wonders and Ray Romano.
The series follows the former Saturday Night Live actor as he navigates unique family dynamics and the complexities of fame to build meaningful relationships. Falco played his mother and Pesci starred as his grandfather.
Written, produced by and starring Davidson. Bupkis is produced by Lorne Michaels for Broadway Video and is written and produced by Judah Miller and Dave Sirus alongside executive producers Andrew Singer and Erin David. Jason Orley directs and is co-executive producer.
Davidson has kept a relatively low profile in recent months. He is currently on his Prehab stand-up tour. In October he returned to Saturday Night Live to host the program, in November he signed with WME and in December he starred opposite Eddie Murphy in the film The Pickup at Amazon MGM Studios.
Davidson said, “I’ve always seen Bupkis as a window into my life, since it is so personal and about my struggles and family. After nearly a decade of my personal life being in the media I wanted a chance to tell my story my way. Of all the work I’ve ever done, Bupkis is by far what I’m most proud of.
I am so grateful to Lorne Michaels and Broadway Video, Peacock, Universal Television and the amazing cast and writers for helping me create something honest, funny and heartfelt. I do also feel that this part of my life is finished. I’m very excited for this next chapter and for you guys to see the work. Thank you to all who support me for I am forever grateful.”
