Olshan Realty's $4M-plus weekly tracker shows 14 signed contracts above $20M year-to-date through May 9. Same window in 2024: 31. Inventory above $15M ran 38 percent above 2024 levels. The Hamptons is not one market anymore.
We spent April and the first two weeks of May with three brokers across the East End, including a Southampton broker, an East Hampton broker, and an independent Bridgehampton agent who works the $15M-plus segment specifically. Coverage triangulates with Knight Frank's Q1 2026 Prime International Residential Index, Douglas Elliman's Q1 2026 East End market report, Compass's Hamptons research desk Q1 brief, and Olshan Realty's weekly luxury market report tracking $4M-plus contract signings.
The May listing flip in numbers. The two-market thesis with broker-sourced data. Why the spread is widening. The Memorial Day window mechanics. The decision framework for $5M to $10M buyers versus $15M-plus buyers.
The May listing flip, in numbers
The mechanics first. May 10 to May 22 is the window when new listings hit the East End MLS at summer-priced rates, which means owners and listing brokers anchor on what they want for the property given peak-season demand. The market then has three to four weeks (through mid-June) to validate the asking price. Listings that get offers in that window go to contract before July. Listings that do not get offers reprice the week after July 4, and the new ask typically lands 7 to 12 percent below the original.
The 2026 read is unusual. Olshan Realty's weekly luxury market report for the four weeks ending May 9, 2026 showed contract signings in the $4M to $9.99M range running 14 percent above the same period in 2025. Signings in the $15M-plus range ran 22 percent below the same period in 2025. Two slices of the same market are doing opposite things. That is the shape of the 2026 spring.
The $5M to $10M Hamptons market is clearing in two weeks
The entry-tier read. Brokers we spoke with described $5M to $10M listings in East Hampton, Southampton, and Bridgehampton clearing in 8 to 16 days from list-to-offer through April and the first two weeks of May 2026. Per one Compass Southampton broker: if it is well-priced and not on the highway, it has multiple offers in two weeks. We have not seen this kind of velocity in this band since 2021. Knight Frank PIRI Q1 2026 ranked Hamptons-adjacent prime price growth at 4.2 percent year-over-year in the $5M to $10M slice, against a global PIRI average of 2.6 percent. The Hamptons is outpacing global prime in this band.
The driver. Three brokers gave the same explanation: post-rate-cut buyer pent-up demand carried over from 2022 to 2024 inertia. Buyers who delayed pulling the trigger when rates peaked in 2023 are now executing. The $5M to $10M buyer is the most rate-sensitive in the Hamptons market (financing on second homes at this size is common, and a 100 basis point rate move materially changes the carry math). The November 2025 Fed cuts unlocked the segment. New listings in this band that price within 5 percent of recent comps clear in days.
The $15M-plus market is sitting on the shelf
The principal-tier read. Brokers described a structurally different market above $15M. Listings sitting 90 to 240 days are routine in 2026 where in 2024 the same listings cleared in 30 to 90 days. Per one independent Bridgehampton agent who works this segment exclusively: the buyer at $15M-plus is not financing. The buyer is reading the Trump tax-policy headlines, the SALT deduction debate, the New York state estate-tax conversation. None of that is resolved. They are holding.
The data. Olshan's $4M-plus weekly tracker showed the principal-tier (specifically the $20M-plus subset) at 14 signed contracts year-to-date through May 9, 2026, against 23 in the same window of 2025 and 31 in 2024. Inventory in the same band ran 38 percent above 2024 levels. The thesis: at principal-tier net worth, the carrying cost of an additional Hamptons asset is trivial against the cost of buying into an unsettled policy environment. Holding makes sense; selling at full ask makes sense for the seller who needs liquidity; transacting in between is rare in May 2026.
The seller at $20M-plus today is testing the market. The seller at the same price in August is selling.

Why the Hamptons market has split into two
Four drivers separate the entry-tier and principal-tier behavior in 2026.
Interest rate sensitivity differential. The $5M to $10M buyer often carries financing on second homes. Rate cuts move purchase math materially. The $15M-plus buyer pays cash. Rate cuts are irrelevant. Rate-driven demand recovery affects only the bottom half of the Hamptons market.
Tax policy ambiguity at the top. The second Trump administration has not resolved SALT cap status, federal estate tax thresholds, or the New York state estate tax conversation. Buyers below $10M operate inside thresholds where these policies do not materially change after-tax outcomes. Buyers at $20M-plus operate inside thresholds where the policy outcome moves the right after-tax cost of the asset by 10 to 18 percent. Holding until policy clarity is the rational position.
Inventory composition. New construction in the $5M to $10M band is constrained because the build economics make this band the hardest to deliver new product at; land and construction costs do not pencil at the lower end. Resale inventory in this band is constantly turning. New construction at $15M-plus is overrepresented because it is where the build economics work and where developers concentrated post-2020. The result: scarcity at $5M to $10M, supply glut at $15M-plus.
Buyer composition. The $5M to $10M buyer pool includes top-quartile NYC professionals, hedge fund mid-career, and post-exit founders. That pool has grown materially through 2023 to 2025. The $15M-plus pool is global UHNW; that pool has rotated toward Palm Beach, Aspen, and Miami over the past five years, and the Hamptons is competing for fewer marginal buyers in this band.
What this means for a buyer entering the Hamptons in 2026
For the $5M to $10M buyer, speed matters. Listings are moving in days. A buyer who waits for post-July 4 repricing in this band will find inventory thinned and remaining listings repriced upward, not downward. The negotiation leverage in 2026 in this band is access (getting in front of a listing before it hits MLS through a broker with a relationship to the listing agent), not patience.
For the $15M-plus buyer, patience pays. Listings sitting at May 22 will reprice 7 to 12 percent by mid-July. A buyer who waits to make a serious offer until late July on a listing that has sat 60 days enters with negotiation room that did not exist in April. The same listing that asks $24M in May likely transacts at $19M to $21M in August if it has sat through the summer. Per one Compass East Hampton broker: the seller at $20M-plus today is testing the market. The seller at the same price in August is selling.
The 2026 Hamptons summer calendar
Four seasonal turns drive what brokers are watching through the year.
May 24 to 26, 2026 (Memorial Day Weekend). The seasonal pivot. Listings that have not had offers by this weekend get the first conversation about repricing. Buyers entering after Memorial Day should expect higher inventory but firmer pricing through June.
Week of July 4, 2026. The second pivot. Listings that have sat six weeks reprice. New listings entering this window are positioned for serious buyers, not aspirational sellers. The July 4 to August 1 window is the most predictable for serious transaction velocity.
Hampton Classic, August 24 to September 1, 2026. The social-momentum window. Listings that come on this week price into the equestrian and charity event traffic; serious buyers tour Labor Day Weekend. Sellers who time well capture top-of-market on listings.
Mid-October 2026. The seasonal close. Listings that have not sold by this point either pull until spring or accept material reductions. The November market is real but thinned; transactions in November to February run at 30 to 50 percent below summer-month volumes.
The practical implication. A buyer entering in May 2026 should know which window they are buying into. The May to June window is the seller's window in the bottom half and the buyer's window in the top half. The July 4 to August window is mixed in both halves. The September to October window is the buyer's window across the board.
The Bryant read on Hamptons real estate in 2026
The Hamptons in 2026 is structurally two markets. The $5M to $10M slice is the strongest velocity it has seen since 2021, driven by deferred demand and rate-cut financing math. The $15M-plus slice is the weakest velocity it has seen since 2019, driven by tax-policy holding patterns and competitive geographic alternatives at the top.
The spread between asking and trading has widened materially in the top half and compressed in the bottom half. That is the market's actual shape in May 2026, not the Q1 narrative most coverage anchored on.
