You can sell them right now at WSEX for $7 a share. So you would win 5 bucks. You can dump them at anytime or hold them. But if he wins, the shares cash out at 100 each. I doubt he'll win the whole thing but I'm getting more and more convinced he might just screw up the whole AI competition.
But I'd hold on to it for now cause he'll still be on for at least a couple more weeks.
