The Minnesota Vikings treated American football fans to a wild finish after Stefon Diggs scored a 61-yard touchdown right at the death to beat the New Orleans Saints.
But the result was every bit the roller coaster ride for the betting community as well.
The last-second touchdown put the Vikings up 29-24, and by NFL rule, they were required to at least attempt an extra point.
But with no time left on the clock and with the win beyond doubt, the Vikings decided to burn the potential extra point and take a knee.
This etched the five-point margin in stone, leading to reportedly over US$1 billion changing hands in the betting community.
