Take a day off

buy/build a house at boat club, open a cafe and just deposit rest of the amount in bank. might buy some land too.

ps. boat club is a place in chennai that's known for its insane land price.

Well, my "if I won the lottery" fantasy only requires a few million. One by one, I'd tell my mates to come check out my new place, which turns out to be a condo at Circuit of the Americas. While we're overlooking my collection of mint-condition shitbox cars that have no reason to be preserved, I'd hand them a check for enough money to wipe out their debts and buy a house... along with a non-disclosure agreement.

Then I'd disappear for a while, taking a road trip around the country without any sort of financial or scheduling concerns. Just show up in a random city, spend a few weeks seeing all the sights at my own pace, then moving along whenever I feel like it.

Going from millions to billions, I doubt I'd deviate from that plan too much. Once I've got myself and my mates set for life, I guess I'd set the remaining 4.9 billion pounds aside for any impulse buys, like an F1 team or a couple hundred politicians.

Setup solar panels with 99% of it then probably die in an orgy of hedonism with the remaining 6 million.

I would create a trust for my daughter, an annuity for my wife that includes payments for healthcare, and a separate fund for property tax and home maintenance to ensure my daughter has a residence and doesn't have to settle later in life.

Next, I would through my friend list (it's not big) and pay off mortgages for those that have them, and purchase homes outright for those that don't.

Finally, I would use the remaining funds to buy up and then forgive US medical debts for pennies on the dollar. This last one would probably exhaust the funds, but would have the broadest positive impact on people.

Quit my job and travel for a while. I'd give 15% to family\friends. I also tend to be partial to the poor\homeless so I'd probably start a program to house and feed those that need it in a big way. And I'd invest 50% of it so I was wealthy, period. In my will, I'd give it all to children's hospital's around the country\world.

Keep and invest 5 million. Give the rest to my city and schools.

Investments, trust funds, paying off debt and my mortgage. Set up enough in investments that I'll always have a million or so in post-tax interest income.

Trust funds and investments for my family so they have money coming in.

Remodel my house.

Rent a condo in Wrigleyville during the Cubs season. Rent a condo in Mesa during spring training.

Open a bar or two.

Hire a dietician/personal cook.

Buy a handful of cars, the most extravagant would probably be a Catterham.

Open an automotive shop to restore cars. I know that'll be a loss but it will be a good hobby for something I like to do.

Travel a bunch. Follow the Cubs for a season and go to every game.

Buy dual citizenship somewhere.

Donate to AOCs campaign.

Club 33 membership.

Occasionally take private jets when I fly, but pick up families that are flying coach when I go and bring them along for free. It's no fun being alone.

Do a bunch of the traditional billionaire things like go fishing on a private yacht.

Finally not stress about going out to dinner.

So after taxes about $4B?

Take 500 million out for me, start a business and do all the stuff we want to.

If possible: Use the rest for a fund for perpetuity to fund transit all over my city, make the buses free and running every 15 minutes, and pay the drivers and all the other workers a really good wage.

If that's impossible, I guess I have to run for governor, win, and Make Florida Freaky Again! Work for the good of our state. Is billions enough to do it?

I may keep 1m, that's way more than what I need to live this life and donate the rest to hospitals and education institutions.

After buying a home in a nice, non-HOA demon neighborhood, probably end up working on a company that makes mid-range phones with a headphone jack, slot for 2 SIM cards and a microSD, and have the system run on a 3rd party Linux OS capable of running APK files and other android apps. I'd definitely wanna have good R&D put into making sure it sandboxes android apps and makes it only allowed to see what's in the sandbox, though, so go*gle cannot see what you do.

That, or just straight up start up my idea for the Open Access Oasis community, where we believe open access to all scholarly articles found on databases like go*gle scholar and other such sites should be free in order to create a brighter tomorrow. Only exceptions to that being things like malware, viruses, worms, Trojans, etcetera, hidden behind a paywall not going open access because most people would just end up damaging their own devices. The idea I had/have for the logo is a playing card of the dual king in a lab coat being hung with an oasis in the background. That, and the card suit being a $, a king of $.
