The Guinness World Records entry for the heaviest Pokémon lists the same weight. Celesteela is an Ultra Beast, and you can read about the whole group in the Ultra Beasts list.
Across all Pokémon, the average weight is 67.0 kg and the median is 28 kg. Only 18 Pokémon weigh over 500 kg. Snorlax weighs 460 kg. Wailord is 14.5 m tall in the Pokédex but weighs 398 kg.
Heavier forms
Some forms are heavier than their normal Pokémon. These are the heaviest forms in the data, from the heaviest down:
- Primal Groudon 999.7 kg, Mega Metagross 942.9 kg, Origin Dialga 848.7 kg, Ice Calyrex 809.1 kg, Crowned Zamazenta 785 kg, Mega Steelix 740 kg
Gigantamax forms are left out of the weight lists. The games give their heights as "more than" a number, and they do not give Gigantamax weights at all. You can read more in the Gigantamax list.
Can a Pokémon be even heavier?
Yes. The Ability Heavy Metal doubles a Pokémon's weight. If Cosmoem or Celesteela gets it, with Skill Swap or Entrainment, its weight becomes 1,999.8 kg. That is the heaviest any Pokémon can be in the games.

Moves that care about weight
Four moves use weight to decide how hard they hit. Heavy Slam and Heat Crash hit harder when the user is heavier than the target. Low Kick and Grass Knot hit harder when the target is heavier.
