Just fell down this rabbit hole of the world's most expensive things and honestly some of these are wild. Like, there's a yacht called the History Supreme that costs $4.5 billion. A YACHT. It's got gold and platinum all over it, took three years to design, and apparently a Malaysian billionaire owns it. That's not even the biggest yacht though - Jeff Bezos has a bigger one that 'only' cost $500 million lol.

But here's where it gets weird. There's a dead shark preserved in formaldehyde that sold for $8 million. An actual dead shark. Artist Damien Hirst made it and some hedge fund guy bought it. I don't get it but apparently that's fine art.

The real estate stuff is insane too. Mukesh Ambani (richest guy in India) has this 27-story building in Mumbai called Antilia worth $2 billion. It has three helipads and a 50-seat movie theater. Meanwhile there's a mansion on the French Riviera worth $506 million that used to be a hospital.

And don't even get me started on the art. A Picasso painting went for $104 million, but a Paul Cezanne called 'The Card Players' is worth $275 million - owned by Qatar's royal family. There's also a Chopard watch with 874 gemstones worth $25 million.

Some of the world's most expensive things honestly seem pointless (the shark, that domain name that sold for $16 million), but I guess when you're that rich it doesn't matter. Makes you think about what counts as an investment vs just flexing, you know?
