The movie, which also featured Noomi Rapace, premiered on December 22 last year but was panned by the critics.
It is, however, the highest viewed film ever on the service in its first week of release and one of the biggest originals they have ever launched, according to Netflix.
The streaming giant released a teaser with a video of orcs auditioning for the sequel.
"Announcement: Orc auditions for the 'Bright' sequel are now closed. Thank you. Have a nice day," Netflix tweeted.
Ayer was in India last month to promote the film with the star cast and expressed a desire to explore the "Bright" universe further.

Film's producer Eric Newman had also confirmed plans for a sequel.
"Hopefully, we get to make more 'Brights' and if we can do that and do a scene here in Mumbai, that would be great," Newman, who is also one of the producers on "Narcos", had told PTI.
Writer Max Landis, however, is not returning for the sequel, reported Variety.
"Bright" revolves around a human LAPD officer and his Orc companion as they patrol the streets. They battle their prejudice and mistrust to protect a relic, which in the wrong hands, could destroy the world.
