In 1951, Citation became the first horse to win one million dollars. In 1979, Affirmed became the first horse to break the two million dollar barrier,  finishing his career with earnings of $ million. Spectacular Bid broke this record in 1980, amassing career earnings of $ million.  Purses began to increase sharply soon afterwards thanks in large part to the Breeders' Cup. The next record holders were John Henry, who earned $ million by the end of his career in 1984 and Alysheba, with earnings of $ million by the end of his career in 1988. Cigar was the next to hold the North American earnings title, finishing his career in 1998 with earnings just shy of $10 million ($9,999,815). That remained the North American record until Curlin in 2008, who earned $ million.  California Chrome broke this record in 2016 with career earnings of $ million, and was in turn surpassed by Arrogate when he won the 2017 Dubai World Cup to take his career earnings over $17 million.
