IF THE POWERBALL DOUBLES ONE MORE TIME...

  1. Then for the first time ever it would be a winning move to buy every possible ticket.
  2. This will cost you about $600 million.
  3. But your after tax winnings will be more than $600 million.
  4. Except...
  5. If someone else wins too you have to share.
  6. And then you'd be out $300 million.
  7. So don't buy every ticket.
  8. It's not actually a winning move.
