GDP is also flow through a country from productivity to revenue realized. Every country is not adding its flat GDP to its wealth every year because a majority of the value created from GDP goes to buying other countries GDP in the same way a companies revenue goes mostly to paying for its operating costs. IE, the US has a 20 trillion GDP but only sees around 4 trillion growth a year in national wealth the same way Amazon can have 135B revenue and 4B profit. Of course, the US having a "profit margin" of 20% to Amazons 3% demonstrates its not a one to one comparison, but the they are definitely the more apt comparisons for measuring how large an economic system is, rather than just how much its profiting.

You could also use net worth to quantify how much "weight" Amazon has available rather than what it is actively exerting in influence, in which case it would be around the 35th largest nation considering its 656B valuation. Thats roughly as much as Finland is worth. I didn't use that statistic because I think there is a much wider differentiation between a nations wealth and a companies market cap than USD revenue vs USD nominal gdp.

Here is Forbes making the point:

GDP to market cap is worse. The net worth of a country is not it's GDP. The total wealth of the US is about ~90 trillion.

The estimates for total wealth, however, are really fraught and fluctuate, as does market cap in other currencies.
