I’m looking for names for big corporations for a story that I’m writing, the story takes place in an alternate universe, where magic and technology have merged together and big corporations rule the world.

There are a variety of ways you could create company/corporation names, even fictional ones.
Here are a couple of options with examples:

1. Name of owner + Corp/industries/etc
Easy and Simple to create, while also giving the owner some recognition/fame/infamy.
Examples: Lexcorp (DC), Wonka Industries (Willy Wonka), Weyland Corporation (Aliens)

2. Acronyms
Harder to do, especially if you're trying to make a word with it, but can be done really well even if you don't.
Examples: OCP (Omni Consumer Products) from RoboCop, CHOAM (Combine Honnete Ober Advancer Mercantiles) from Dune, BnL (Buy n Large) from Wall-E

Honestly, the name of the company should be either memorable or relevant to the story, preferably both though.
Hope this helps!

Celestial Heavy Industries

They make most of the nations cars, ships, planes and whatever lol.

More than usual. That's the name of a major corporation in the Fallout: Equestria setting.
