A little over ten years ago I cofounded a startup in Boston that was attempting to do something along these lines. We couldn’t believe how much money people were spending on such a bad investment. We were going to sell our own scratch tickets that had a positive EV. You’d scratch a ticket and reveal a code which could be redeemed for a fractional share(s) of stock in one of a basket of companies. The hope is we’d come close to the entertainment value while at the same time helping people save and earn a massive jump in ROI over regular scratch tickets (which paid 50 to 85% or so). The numbers would work at scale if people liked it. We weren’t the right people to do it, but I hope other people someday will offer something similar. Stockcards is something a little close to it, which is cool to see.
