Such high amount of $ combined with the fact that the Saudi's want local production as part of their 2030 vision, I bet they want the Kaan too.
It fits their airforce perfectly, replacing the oldest F-15's while having the same engine as the rest of their F-15 fleet. Basically a more advanced and stealthy F-15.
Kaan is just the beginning, there have been statements issued that TAI is working on 6th gen, but also on a smaller Kaan slightly larger than an F-16, most likely single engined which can compete with the F-35 and Su-75 on the global market. This isn't a concrete plan yet, but has been mentioned by Temel Kotil twice now. Once in an interview in may last year and more recently after the first flight.
