how many mega millions tickets do you have bbv4l

I've heard of companies that somehow buy every single number in a lottery once it becomes +EV to do so. I'm not sure if the annuity is +EV at the moment (~ 1:175,000,000) on a $325,000,000 jackpot before taxes, or if it would be worthwhile to buy out a lottery for an annuity payment, but I'd like to know if these companies exist.
