Go for it!*

*Brainteaser: what are the caveats?
You will of course “win”, but I can see four real caveats. First, you need to fund this up front, on very short notice, so you better have your friendly Credit Suisse banker on speed dial. Second, while the headline prize amount is in the $2B neighborhood, the equivalent upfront after tax cash amount is more like $540MM. A good tax lawyer might find a way to deduct the cost of the tickets, but again, time is of the essence here. Third, how do you actually go about procuring a couple of hundred million tickets in a day or two? I’ve also never bought a ticket in one of these things, so this one may just be a matter of my ignorance. And last, but certainly not the least, there is a very good chance that you may have to share the prize, and possibly with multiple other winners (who, unlike you, will probably be ecstatic!).Current US Powerball lottery prize: ~$1.9 Billion.

*Brainteaser: what are the caveats?
yeah, the wrong ones.Is there any data for what numbers people choose? (Bill Ziemba would have loved this!)
For example, a casual gambler who enters a casino with $100 and redeems his or her tokens for $300 after playing the slot machines has a wagering gain of $200 ($300-$100).
Retailers as Players. Subject to any restrictions placed by the Lottery, Retailers are allowed to purchase and play Lottery games and products. Retailers that play Lottery games and products are required to pay for tickets in full prior to play and are subject to the same rules, conditions, and Lottery regulations as non-Retailer players. Failure to follow any of the Lottery’s rules, conditions, or regulations will result in the denial of Retailer’s prize claim and may result in Contract termination.
It's a good idea.The old story was that you should include numbers greater than 31 in your choices, assuming you're not buying every combination.
This is because a lot of people use dates for their numbers, and you'll limit your likelihood of having to share with very many of them.
For clarity, I’m not opposed to partaking in games of chance. I was merely stating a fact. I’ve played plenty of poker and, while I know that can be considered a game of skill, I’m well aware that my skill level is such that I’ve got to count on some luck. I’ve also been intimate with many a one-armed bandit in Vegas, going back to the days when they actually had an arm that did something. Who knows, I may yet go out and buy my first state lottery ticket tomorrow. How hard can it be? It does seem a bit of a leap to buy a couple hundred million of them, though.The stress...The risk of losing a quarter of a billion pieces of paper in the washing machine...technicalities about being a resident of the states that have the lottery...the publicity that comes with winning/"cheating"/accidentally losing...
I've bought the occasional Powerball ticket when I've been in NYC. Am currently in the UK and the Powerball app I tried using insists on knowing my exact location and won't let me buy even one ticket!
(It always amuses me how otherwise totally irrational people insist on never buying lottery tickets! And telling me about it! There's a strong case to be made for bearish to be locked up in a room with padded walls, but, oh no, he'll never be mad enough to buy a lottery ticket!)
So, how many tickets are we going to buy? In whose name/state? Who has the technical skills to automate the online/app buying process? Which numbers do we choose (that's why we need the data about popular numbers)? I own part of a racehorse, this can't be any worse than that!
