Another fact that many don't realise.
More An124's (36) were assembled in Aviastar-SP in Ulyanovsk than in Kiev Aviant. (18)
There were over 100 factories across the USSR connected with the production of the An124.
This was a USSR project.
All of which comes back to the point that the An225 is dead and buried unfortunately.
The only likelihood of a resurrection of An124 production lies within Aviastar, for the simple reason that they have an actual client who might have a requirement for such an aircraft.. the Russian Airforce.
And even this is extremely unlikely, as they have enough airframes for their requirements, and stored airframes which could be used either for parts, or to complement numbers.
A new engine would also likely need to be fitted for any new production anyway.
The resources they have make it seem likely they will utilise these until a replacement heavy lifter is needed sometime in the near, mid, or distant future.
And finally, the production jigs no longer exist in Kiev, apart from the tail unit jigs.
The production jigs are still intact at Aviastar.
Edit: The suggestion I confused Antonov with Tupolev by a poster is just ludicrous..
