For the sake of argument, I'm going to say it's not a sport (yes, I'm actually saying this in a flood of overwhelming supportive comments in a Q&A thread for some reason). If it somehow is a sport, it would be a terrible choice.
Let's compare it with chess and 100m sprinting.
1. No spectacle or interaction
The public judges activities on spectacle. There's no debate about that. Sprinting has a lot of spectacle. We view them in front of a big screen, with our hearts pounding in unison, hoping that one of the runners that we support would win. Stadiums are often packed to see who runs the fastest in a 100m race. While chess does not have a lot of spectacle in itself, the board is often projected on a massive screen, with commentators picking up where the players left off, and allows the audience to interact by thinking through each move along the way, generating a substantial amount of hype. Beyblade, however, doesn't typically generate enough hype for most of us to care. It's pretty pathetic when your stadium and your spinning tops are that small, no? It feels really underwhelming, and you can't really interact with the situation as a viewer, since pretty much everyone's already done substantial testing on most competitively viable combos. It'd be really boring if chess grandmasters recreate the exact same game over and over again.
2. Lack of decision making from the competitors
Chess is a game where both players fight for control over the board. There are a lot of decisions to be made, and it is possible for the best players to make mistakes. While sprinting doesn't require a lot of decision making, every step must be powered by the athlete. Throughout the entire process, both chess players and athletes could influence the game. Beyblade, on the other hand, has only two critical decisions available, namely the launch technique and combo customization, and the latter has significantly more impact than the former. You can't change beyblades mid-match, only slight adjustments to mode-changing tips, frames or launch techniques, which makes the matches after the first one really boring to watch. Sports with numerous rounds such as tennis is interesting to watch, because endurance is also an important factor, and so the match isn't always based on skill or power. I don't really think that launching multiple turns would be too tiring in particular, so there isn't too much of a variation to launching, thus the match has already been decided before even launching. This is by no means satisfying to anyone. 3 on 3 is slightly more interesting, but that's pretty much it really. A sport that determines the victor by their equipment and not their skill is boring for everyone involved. Even MTG adds in a bit of luck into the mix, and the players make active decision throughout the entire match. But with Beyblade? What happens after your first launch? You have no power to further influence the battle. The only time I see this being subverted is the RC and SC beyblades, and even then the remote control feature is a bit tacky with possible EM interference, not to mention that only a few beyblades could be controlled.
3. A monopoly on beyblade production
Somebody has already mentioned this on the "beyblade as legitimate sport" thread already, and I'll just leave it right here.
