Steam

Based take imo. I think many posters fail realize the insane amount of money steam makes Valve. Rough estimates are that Steam sold 400 million games last year. Average cost for a game is ~$15.5. Steam has a platform fee of 30%. That means that, roughly, Steam made Valve ~1.86 billion dollars just through the sell of games. Not considering microtransactions or hardware sells. Reportedly, Valve made 1 billion dollars just off cases from CS2 crate openings. Let's just give Valve the benefit of the doubt and assume they made $5 billion dollars last year.

Impressive, but honestly not that impressive when you consider that Xbox brought in 18 billion and PlayStation brought in 30 billion last year. However, if you factor in that Xbox has a head count of ~$20,100 and Sony has one of ~12,700. While Valve has a head count of about ~400. We see that Xbox and Sony are bringing in about $900K and $2.4M per head respectively. Valve is bring in 12.5M per head. Plus Xbox and PlayStation have multiple studios and campuses. While I believe Valve only has the 1 or 2 campuses and they are their only studio.

My point being that, Valve has a ton of liquid cash for investment and growth opportunities. I'd wager Valve brought in more than 5 Billion last year, but with them being a private company, it's hard to pin down what exactly they could've made.
