It is owned by the New Jersey Sports and Exposition Authority and is operated under a five-year lease as a partnership with Darby Development, LLC.

In May 1894, the Township Committee at Eatontown, New Jersey ordered the seizure and sale of the Monmouth Park Association's grandstand and other property for the payment of back taxes and on May 7 was sold at a public auction.

The bill was championed by Amory L. Haskell, who led the legislative charge to once again permit wagering on horse racing in New Jersey and Philip H. Iselin, a New York City textile magnate.

They also had the backing of Reeve Schley, Joseph M. Roebling, John M. MacDonald, Townsend B. Martin, and James Cox Brady, Jr.

In 2012, the festival moved to the PNC Bank Arts Center in nearby Holmdel, New Jersey due to financial considerations.

The agreement allowed Resorts to sponsor the Haskell Invitational, and possibilities include a merging of loyalty programs as well as bringing entertainers' appearances at the casino to the racetrack.

[16] On May 16, 2024, Monmouth Park held a ceremonial groundbreaking for a new 16,000 sq ft (1,500 m2) trackside sportsbook operated by Caesars Entertainment.

The new sportsbook will be located at the track's first quarter-pole and host a Shake Shack, self-service betting kiosks and indoor and outdoor seating overlooking the racetrack and the infield.

The Wolf Hill Farm, which served Monmouth Park as a private stable and practice facility, was located adjacent to and immediately west of the main complex.

Wolf Hill, owned and operated by the Valentino Family from the nearby City of Long Branch, New Jersey featured barns, stables and a practice track featuring a dirt oval and turf course identical to that at Monmouth Park's main facility only built to 50% scale.

It was transferred to state ownership in the 1986 takeover by the NJSEA and was eventually sold to the Monmouth County Park System in 1998 which now operates the site as Wolf Hill Recreation Area that features a 4-acre dog park, an 18-hole disc golf course, a baseball field and two softball fields.

This was done due to the recent monetary losses of the racetrack industry in New Jersey and made it the most expensive purse structure in North America at the time.
