I came across a press release headline: "Global edtech major upGrad raises USD 120 million"
In the article, there is also a sentence that uses "edtech major":
This is the first external funding raised by the edtech major.
I know that "edtech" is "education technology", but what does "major" mean in this context? It seems to mean "company", but I don't see that definition in the dictionary entry for "major".
