When Barstool Sports founder Dave Portnoy dropped a staggering $42 million on a waterfront compound, he didn't just buy a summer vacation home. He shattered real estate records on the island. Located on Monomoy Road, the purchase immediately became one of the most expensive residential real estate transactions in Massachusetts history. For a media mogul who has long professed a deep love for the island, calling it his favorite place on earth, this sprawling estate represents the ultimate island sanctuary.
The property sits directly on the harbor with unobstructed sunset views, blending extreme privacy with high-end modern design. Far from a standard coastal cottage, the compound spans multiple lots and features high-end structural quirks that make it a frequent subject of fascination.
The Monomoy Compound Layout and Design
The estate spans roughly 1.2 acres across two adjacent parcels at 68 and 72 Monomoy Road. Before the modern transformation, the lots held older structures that were entirely redeveloped following a 2016 sale. The final architectural product is a masterclass in coastal luxury.
The main house offers roughly 5,200 square feet of meticulously designed living space. Expansive glass walls frame panoramic views of Nantucket Harbor from nearly every room. Alongside the main residence, the compound includes a dedicated two-bedroom guest house to accommodate visitors, family, and friends during peak summer months.
Outside, the landscaping transitions seamlessly into a custom infinity pool that appears to spill directly toward the harbor waterline. Paved stone decks surround the pool area, providing ample space for outdoor entertaining, relaxing after a long boat ride, or hosting friends from the media and sports worlds.
The Famous Underground Tunnel
One of the most talked-about features of the Dave Portnoy house Nantucket compound is its hidden architectural quirk: an underground tunnel. Connecting different sections of the property below ground, the subterranean passage adds an extra layer of privacy and seamless movement between the main structure and auxiliary quarters. While coastal properties often face strict local zoning and building codes on the island, this feature separates the estate from standard waterfront builds, adding to its mystique and multi-million-dollar valuation.
Breaking Island Records
The transaction price stunned local real estate agents and national markets alike. Portnoy purchased the property for $42 million, with an additional reported $2 million shelled out for high-end turnkey furnishings, bringing the total investment higher. This eclipsed the island's previous residential record, which had been set earlier that same summer at roughly $38 million.
Real estate records show the land previously traded for a combined $13.3 million in 2016. The massive appreciation reflects both the soaring demand for premier New England coastal real estate and the specific hyper-luxury trajectory of Nantucket's Monomoy neighborhood.
Elite Neighbors in Monomoy
Living in Monomoy puts Portnoy in an exclusive club of ultra-high-net-worth individuals, tech titans, and corporate legends. The neighborhood has long attracted prominent figures seeking seclusion away from the mainland. Portnoy's immediate neighbors and area residents include billionaire financial heavyweights, retail moguls like Tommy Hilfiger, and prominent sports team owners.
The area offers deep-water access, calm beaches, and protection from the harsher ocean swells found on the island's south shore, making it an ideal spot for boating enthusiasts.
