The Jockey Club is projecting a North American registered Thoroughbred foal crop of 18,000 in 2024. This represents 500 fewer foals than the 2023 foal crop estimate of 18,500.

The foal crop projection is computed by using Reports of Mares Bred (RMBs) received to date for the 2023 breeding season. RMBs are to be filed by August 1 of each breeding season.

 Additional foal crop information is available in The Jockey Club’s online fact book at and in the online state fact books.

 Stallion owners who have not returned their RMBs for the 2023 breeding season are encouraged to do so as soon as possible. Interactive Registration, which enables registered users to perform virtually all registration-related activities over the Internet, is the most efficient means of submitting RMBs and is available at
