When Barstool Sports founder Dave Portnoy dropped $42 million on a waterfront compound in Nantucket, Massachusetts, he shattered the island's residential real estate record. Located in the exclusive Monomoy neighborhood at 68 and 72 Monomoy Road, the estate spans 1.2 acres of prime harbor-front land. It isn't just a standard summer beach house; the property features high-end architectural design, expansive sunset views over Nantucket Harbor, and unconventional luxury perks like an underground tunnel.
Portnoy, who long called Nantucket his absolute favorite place on earth, upgraded from his previous island holdings to secure one of the most expensive private residences in Massachusetts state history. Here is a close look at the layout, features, and financial details behind the headlines.
The Record-Breaking Purchase and Location
The off-market transaction closed in late September 2023, brokered locally by Lee Real Estate. The price tag beat out a short-lived record set earlier that summer when another Nantucket estate sold for $38 million.
The compound sits directly on the water in Monomoy, a quiet, wealthy enclave known for privacy and multi-million-dollar estates. Portnoy's immediate neighbors include prominent business figures, designers, and billionaires like Tommy Hilfiger and Charles Schwab. The location provides direct access to Nantucket Harbor, offering unobstructed 180-degree sunset views across the water.
Property Breakdown and Interior Features
The 1.2-acre compound is formed by combining two separate lots (68 and 72 Monomoy Road) that were redeveloped extensively after being purchased in 2016 for roughly $13.3 million.
The main residence and guest quarters offer roughly 5,200 to 8,600 square feet of total living space, featuring high ceilings, natural wood finishes, and massive glass walls oriented toward the harbor.
- The Main House: A beachfront structure featuring expansive living areas, custom kitchen installations, and multiple bedroom suites that overlook the water.
- The Guest House: Separate quarters providing multiple bedrooms for visitors, matching the architectural styling of the main building.
- Turnkey Furnishings: The purchase included roughly $2 million worth of bespoke furniture and interior decor, meaning Portnoy didn't have to spend months staging or outfitting the rooms.
- The Underground Tunnel: One of the most talked-about architectural features of the estate is a subterranean tunnel connecting parts of the property. Underground passages have become an emerging trend among ultra-luxury coastal builds to allow movement between structures during harsh winter weather or for private service access.
Outdoor Amenities and Harbor Views
The exterior of the property functions as a private waterfront resort.
The backyard features a custom infinity pool flanked by stone patios, a covered outdoor lounge area with an exterior television, and private beach frontage. Because the property faces west across the harbor, the outdoor decks provide prime vantage points for evening sunsets.
