Build a high-speed train from Columbia, SC to Charleston, SC. In the grand scheme of things, it might seem like a waste of money. But man, for the few dozen years I’ve got left on this earth, it would be awesome to see & experience.

Go to a casino and walk up to a roulette table and put it all on black.

I'd get a house for me and my family. Make sure my parents have a house that meets their needs as well. I'd hire a personal trainer to get in shape and take a few months off work while I figure out what to do next.

Pay off the mortgage and quietly live out the rest of my life, probably on the interest alone.

Start my own research company.

Safe investments to make sure it lasts and then I want to start a charity to help people get access to mental health care, help feed the homeless, and do other stuff for my community.

Also pay off debt and finish college

First, I would purchase my favorite charity from the lovely lady (a friend of mine) who runs it for 10 million. Then I would expand its reach a lot.

first thing I'd do is buy my mom a house and py off all our debt. It'd be nice to have some time alone as an adult without having to leave her homeless or whatever. Next I'd find a restoration shop for my truck, buy the shop and make them fix my truck. Why buy the shop? Why not I've always wanted to be an automotive restorer and now I've got whatever is left after taxes and fees. Then I'd probably have my own house built the way I want it. After that idk. I'd have more money then I'd ever know what to do with, have my own shop with the latest and greatest gear and the best mechanics around. I'd hav le my own house and my mom would be taken care of. I'd probably buy my best friend and her parents a house, afaik she still lives at home and her parents rent.so that'd be doing them a big favor.

Hide it.

Find a reputable institutional advisor who specializes in this sort of thing. Pay off debts. Quit my job. Eventually begin planning some charitable gifts, perhaps even a foundation or something. Make life meaningful that way.

I would use the entire $1 billion to buy company stocks and use them to try stop their bad behaviors/investments, like stopping Big Petrol from polluting more, Google from spying on their users, etc.

I’d buy an electric car, a 40 watt laser engraver, I’d build a workshop in my side yard, install a vented hood, get some new larger 3d printers, a paint airbrush system, set up a bicycle repair area, and set up a computer workshop in there. And never leave my workshop.

Pay off all debts and mortgages for myself and my immediate family, then put away whatever’s away into separate HYSAs for a few months to let the initial rush go away.

Hire and accountant. Taxes are too complex and most lottery winners are bankrupt in 10-20 years as they fail to budget correctly.

I'd probably pay off my house, upgrade the furnace to a heat pump (something i'm doing with the next bonus anyway) turn the rest over to charities. Though with that much money finding charities that can even accept that much money is hard.

Have you ever seen office space? Peter's answer or his neighbor's answer. Probably both.

Hire an accountant.

With a billion I could probably buy a huge island just for myself but in all honesty I just need a million so I can retire. It's more than enough.

Put it in a bank earning 4% interests and live off of it for the rest of my life. Yeah I'm a simple man.

Whatever the hell I wanted to do. Rich people don't go to jail.

I hope I could have it pay out maybe $1 million a year for 1000 years. If not…

I would find a financial advisor how to save and invest properly so my money could make money. I would give a bunch to my parents and sibling so they don’t have to worry. I’d give a bunch to my extended family. I would give a bunch to my friends. I would restart a nonprofit I was a part of. I would build housing and a support system for unhoused people. I’d buy some medical debt on the market to forgive it. I would lobby a few politicians to do some good things. I would travel some.

Pay off my house, do all the little projects in the house we couldn't afford, save enough for the kids college fund, and buy a few shiny toys. Then go back to work like normal...I'd go insane with nothing to do all day. On the plus side, my family will have the most amazing vacations.

Pay off all my and my immediate family's debt. Renovate my parents home or get them a new one, give my sister a nice home wherever she wants, buy myself a new, basic vehicle for my commute, and get a nice place for myself close to my work. I'd also start my own creative studio to work on the game I've been making. And, also try to put my excess money to good use by trying to help out people with housing issues and health problems. All while keeping the fortune a secret.

I don't wanna remain a millionaire.
