Which company is the largest in Oslo depends on how you measure. You can look at valuation, at revenue or at how many people work there. Valuations are private for most companies, so here we stick to revenue and headcount.

By revenue, Axis-Shield AS comes first in Oslo. It is part of a group with $40.8 billion in yearly revenue. By headcount, Posten Bring AS comes first with 10,237 employees. We only looked at the 85,312 corporations in Oslo for this; sole traders, foundations and other legal forms are left out.
