From the actual example of crocodilians alligators, speculations can be made in order to estimate the maximal weight that a "megatheropod" could reach. They don't say they effectively had this weight. But it was possible.
And the "final winner" (the most heaviest) can amaze you, but not that much if we consider it was an ancient theropod converted into a vegetarian animal...

" Megatheropods were the most powerful terrestrial carnivores in Earth's long history, and recent studies show that theropods like Tyrannosaurus may have been bigger than expected. The Mesozoic was a beautiful nightmare, and the rulers of that nightmare realm were the megatheropods: bipedal dinosaurs closely related to birds but bigger than African elephants. The elite group includes household names like Tyrannosaurus, Spinosaurus, and Carcharodontosaurus, each of which had unique adaptations that cemented them as apex predators that would be terrifyingly alien to us humans. While other beasts like sebecids, huge bears, and hyaenodonts were fearsome in their own right, none even came close to the level of the megatheropods. But among the most formidable theropods to ever walk the earth, only one species could truly claim the crown of the biggest ever. What was that animal? How big could it really get, and what would its size tell us about its ancient ecosystem? These dinosaurs were the biggest land predators ever.
