From DRF tonight:

"The pick six? That was in another atmosphere entirely. No one picked six, and the 40 $2 tickets with five winners among the sequence of Intercontinental, Silver Train, Artie Schiller, Pleasant Home, Shirocco, and Saint Liam, were worth $90,325.30. The total pool for the pick six, which was guaranteed at $3 million, was $4,586,699."

"How difficult was the pick six? A panel of three handicappers who put together a $93,312 Players' Pool ticket for the AmericaTab online wagering service, funded by customers who have accounts with the service, used nine horses in the Filly and Mare Turf, the first leg of the bet - and was out when Intercontinental won."
