US corporate revenues have never been this concentrated:
The top 1% of US firms by sales now account for a record ~82% of all corporate revenues.
This percentage has risen +22 points since the 1950s.
The top 20 firms alone account for a record 50% of all US corporate sales.
Concentration has increased +10 percentage points since the 1980s.
At the same time, corporate profits after tax as a proportion of US GDP stand at 12%, near an all-time high and more than double 2001 levels.
This means a shrinking number of companies are capturing a growing proportion of both revenues and profits across the entire economy.
The market and economy have never been more concentrated.
