I found that there’s still room for arbitrage in the World Cup. Just now, in the Austria vs. Jordan match in the second half, there was a goal like this: the score was 1:1 at the time, then Austria took a shot and scored. I was watching the predict prediction market, and it immediately lowered the win/draw odds—if it ended in a draw, it reached 1.9X. Then the referee reviewed the VR replay and found that the goal wasn’t right; it looked like the ball first hit the hand—there was a handball before the shot went in—so they wanted to cancel it, but it took a long time; they reviewed it for about 3.
