Been scrolling through some wealth rankings and honestly, the numbers are kind of wild. There are roughly 800 billionaires in America right now, and get this - collectively they're sitting on about a fifth of the entire US GDP. That's around 6 trillion dollars in one group's hands.

But if you want to hang with the absolute elite, you need at least 100 billion. Only 10 people in America have that kind of wealth, and most of them come from tech. Makes sense when you think about how much money has flowed into that sector over the past couple decades.

Elon Musk is at the top with around 200 billion. His money comes from Tesla and SpaceX mainly - though his net worth swings pretty wildly depending on Tesla's stock price on any given day. Jeff Bezos is right there with him at roughly 195 billion, mostly from Amazon. People forget that AWS is what actually makes Amazon the money machine it is, not the retail side.

Mark Zuckerberg hit 180 billion, all from Facebook (now Meta). Dude literally built that from a college dorm and basically invented the social media era. Larry Ellison at 140 billion is probably the least famous of the bunch, mainly because Oracle does backend infrastructure stuff nobody really thinks about.

Warren Buffett's around 133 billion from investing through Berkshire Hathaway. Bill Gates and Steve Ballmer both got their wealth from Microsoft - Gates at 130 billion as co-founder, Ballmer at 120 billion as an early employee who later became CEO. Larry Page and Sergey Brin, the Google co-founders, are both in the 110-114 billion range. Jensen Huang from NVIDIA just cracked the top 10 at 112 billion, and his wealth has been accelerating hard thanks to AI and cloud computing demand.

So yeah, America's richest people are basically all tech guys. Wild to think about how concentrated wealth has become in that sector.
