How Much Is CS:GO Worth To Valve ?

It's no secret that Valve gets good money out of CS:GO's micro transactions. I'm gonna count the average amount of money that Valve makes out of CS:GO.
The game itself Based off to an information from Steam Spy there's 21,352,159 copies sold.

That's not all and if we go into calculations and If we multiply the amount of copies sold with CS:GO's price we get the result of $ 320,068,863(approx.). (Now That's Something)

STEAM MARKET

Steam has a fee called "Steam Transaction Fee" and it only applies to items sold in steam community market. The Fee is currently set at 10% for CS:GO. Based off to csgobackpack numbers total value of items is 211,713,935 $ and if people were to sell them at least once Valve would get 21,171,395 $. This calculation might have a big error percentage since we can't get the exact numbers of ALL the items sold so I'm gonna take example here so you get the idea how much Valve makes daily without actually doing anything.

Here is field-tested AK-47 Redline, as seen above. That item was sold 2028 times in 24 hours and the average price was 5.7$. If we take the 10% out of the 5.7$ and multiply with 2028 we get 1155.96 $. 

Cases, Keys And Stickers.

There is no public data available how many cases there was opened so we can't really go in to those details but Valve said this in their recent blog post "We have shipped over 90 weapon finishes made by the CS:GO community with each finish earning over $40,000 on average" If we multiply the numbers we get that Valve has made 3,600,000 $ from their recent CS:GO skins.
For better understanding the skin values see this video by McSkillet.

END POINT

Valve can do anything and still we will be stupid enough to but anything they throw at us as we seen in past like Music Kits and Gloves. Like that did even make sense up until skins everything is pretty fine but i just hope they didn't turn it into character customisation in future. Hope for the best and pay lord gaben for skins.

EZ!
