The Super Rich Have Turned the Tiny Florida Town of Manalapan Into the Next Palm Beach

Can its real-estate market continue to rise amid stock-market turmoil?

MANALAPAN, FLA.— The Deal-Closer. That’s what real-estate agent Jack Elkins jokingly calls the Hinckley picnic boat he docks on the Intracoastal Waterway in the Florida community of Manalapan.

From the road, many of Manalapan’s mansions are shrouded by plantings and foliage, but they are clearly visible from the water, Elkins explained. A boat ride is often the best way to show properties to the wealthy buyers now flocking to the tiny town.

On a recent afternoon, Elkins cruised down the Intracoastal in the The Deal-Closer, passing mansion after mansion, most with their own docks. “When I was a little kid, almost all of this was jungle,” said Elkins, 46, who spent much of his childhood in the area. “There were foxes and parrots and all these wild animals.”

Manalapan, a roughly 2.4-square-mile town with a population of about 400, is just south of glitzier Palm Beach.

While Manalapan has long drawn moneyed residents such as the singer Billy Joel, it has historically lacked the prestige—and price tags—of Palm Beach. That has changed dramatically over the past five years, however, thanks to a series of major home sales.

In 2022, for example, Oracle billionaire Larry Ellison paid $173 million for a historic Manalapan estate. And David MacNeil, the founder of the automotive-accessories manufacturer WeatherTech, has spent a combined $94 million over the past year on a pair of neighboring sites, with plans to build a megamansion there.

“People like Larry Ellison and David MacNeil, these individuals can afford to buy real estate anywhere in the world,” said local real-estate agent Nick Malinosky of Douglas Elliman . “Manalapan is not a second choice for them. It’s their first choice.”

On South Ocean Boulevard, Manalapan’s most affluent corridor, about 21 homes have traded for more than $20 million each since 2020. At least six have sold for $40 million or more, up from only one in that price range during the previous five years.

In 2021, eBay billionaire Jeffrey Skoll bought an ocean-to-Intracoastal estate for $89.93 million, while Joel’s longtime home sold last year for $42.6 million.

Now, however, it is unclear whether Manalapan’s hot streak can continue. Like luxury markets across the country, the town is contending with stock-market turmoil and the fallout from President Trump’s tariffs.

Like many Manalapan residents, local developer Stewart Satter, who is listing a yet-to-be-built spec home for $285 million, is a Trump supporter. During the 2024 election, Satter flew a giant Trump flag above the site.

But tariffs have “created a tremendous amount of uncertainty at the minimum, and that is not good for business,” Satter said. “It’s not good for real estate. People say, ‘Let’s wait. We’re not going to buy a house, we’re not going to build a house.’”

Hitting the big time

Elkins’ cuddly Native American Indian Dog, Bear, lounged on The Deal-Closer’s blue-and-white-striped seats as the boat zipped along the Intracoastal, passing glassy modern mansions and traditional Mediterranean estates.

To catch a glimpse of Ellison’s roughly 16-acre oceanfront estate, Elkins guided the Hinckley through the Boynton Inlet into the choppy Atlantic, where the sandy beach in front of Ellison’s property was visible.

Known as Gemini, the gargantuan mansion was once owned by the late publishing magnate William B. Ziff Jr., who brought in large plantings and trees from South America for the landscaping.

“When I was a little kid, barges were going by our house with these huge trees,” Elkins recalled.

Ellison has approved plans to add more homes to the estate. He also paid about $277 million last year for Manalapan’s Eau Palm Beach Resort & Spa, home to the members-only La Coquille Club, and talk is rife about how Ellison might upgrade the property. Ellison didn’t respond to requests for comment.

It’s a strange feeling, Elkins said, to see Manalapan hit the big time.

Before Covid, the town was often confused with its namesake: Manalapan, N.J. Tiny compared with Palm Beach, Manalapan developed much more slowly than its famous neighbour. It lacks the commercial infrastructure of Palm Beach, and its low-density zoning has kept it largely free of major condos or resorts.

When Satter, the developer, bought four empty lots in Manalapan in 2005, parts of the town looked like “just a mess of woods,” said his wife, Susan Satter. “I said, ‘Is this really how we want to invest our money?’”

Over the next decade, her husband built spec homes on three of the lots and sold them for a significant profit. He kept one, building a mansion there for himself and his wife.

“I thought I’d discovered a really special place,” said Stewart, who tested products for Walmart before turning to spec-home development. “If I had known what was going to happen, obviously, in the rear view mirror, I would have bought the whole town.”

The buyers of Satter’s projects include Ron and Cindy McMackin, who paid roughly $39 million in 2020 for a roughly 15,500-square-foot waterfront house with six bedrooms, then expanded it.

The couple, founders of the mechanical subcontracting company Pan-Pacific Mechanical, had relocated from Hawaii to South Florida during COVID.

“We knew nothing about Manalapan when we moved here,” said Ron, 78. He and Cindy were in the process of moving into a Palm Beach property they owned when their real-estate agent, Lawrence Moens , called. The actor Sylvester Stallone was searching for a home amid the Covid-induced real-estate frenzy, and wanted to see their house.

Before they knew it, they had agreed to sell to the “Rocky” star for $35.375 million, 33% more than the $26.65 million they had paid two years earlier.

This left them without a house. It was slim pickings in Palm Beach, and with five children, they needed plenty of space. Moens suggested Manalapan. At the time, the less-flashy choice was surprising to some of their Palm Beach friends. “I did hear a couple of times from people after that, ‘Why would Lawrence take the McMackins to Manalapan?’” said Ron.

But the McMackins love that it is quieter than Palm Beach, with less traffic. The couple have Sunday dinners with their neighbours, and Cindy has a small group of girlfriends who call themselves the “Manalapan mafia.” The McMackins like it so much that they are building a new, larger home along the same stretch.

Food-service entrepreneur Bob Carlucci and his wife, Aileen Carlucci, paid $11.63 million in 2020 for a roughly 13,000-square-foot Manalapan mansion on the Intracoastal, with a small beach house on the ocean. They are happy to have “discovered Manalapan early, ” Bob said.

Many buyers are tearing down older homes to build new mansions, Malinosky said. Before COVID, Manalapan was seen as more of a vacation destination, so buyers weren’t as choosy. Now that many are seeking full-time homes, however, “they want to make sure that it has the spa, it’s got the 12-car garage, it’s got the fitness centre, it’s got the wellness centre.”

Another prized amenity is a tunnel that runs underneath Highway A1A. Portions of the town are on a barrier island, and some homes sit on the ocean, requiring residents to cross the busy road to reach their docks on the Intracoastal.

Other estates are on the Intracoastal but have small beachhouses on the ocean. A tunnel allows residents to easily go from one side to the other.

Construction of these tunnels has become a rare point of contention between residents. In January, one couple asked the town commission to stop their neighbors from digging under the highway during the tourist season, claiming it was causing traffic to back up.

Building on the coast comes with challenges. Florida building code now requires roofs, windows and doors in high-risk areas to withstand winds of up to 170 miles an hour, according to builder Robert Burrage, who is building MacNeil’s home and four others in Manalapan.

Satter said the property insurance on his personal residence in Manalapan doesn’t include coverage for hurricane damage because it was too expensive. In addition to the annual premium, which was about $150,000 a year, he would have faced a deductible on hurricane damage of about 10% of the assessed value of the house.

He isn’t concerned with rising sea-levels, however. “When I bought my first oceanfront lot, my late father-in-law said, ‘What the hell are you doing? Don’t you know about global warming?’” Satter said. “I sold it at a huge number [in 2016] and made a lot of money. It’s been sold again and again and again—and the water hasn’t done anything.”

Stock market slide

Manalapan’s proximity to Mar-a-Lago has added to its popularity since Trump’s election to a second term, Malinosky said. Many residents support Trump. In the McMackins’ home, a bedazzled MAGA purse hangs in Cindy’s closet and a photo book in the living room shows her attending a Trump event at Mar-a-Lago, where they are members.

But the trade war and stock-market volatility have injected uncertainty into the real-estate market.

Until recently, Hamptons home builder Joe Farrell was considering paying more than $30 million for a building site in Manalapan, he said. He has decided to hold off on any acquisitions for now, however, because of the tariffs and resulting stock-market fallout.

“The market seems to still be pretty good, but people are maybe a little more cautious about parting ways with liquidity,” Farrell said. “I want to see things stabilize before I commit to that kind of capital outlay.”

Elkins said one of his clients considered backing out of a $10 million deal over the last few weeks on Point Manalapan, but decided to move ahead to avoid forfeiting the deposit.

Malinosky said he still sees significant demand for big-ticket properties in Manalapan, especially since many wealthy people are taking money out of the stock market. He said he has closed more than $150 million in deals in the greater Palm Beach area over the past two weeks.

Even with the uncertainty, “there is no shortage of buyers that will spend $100 million right now in Manalapan,” he said.

Shelly Newman, an agent with the Corcoran Group, said she recently sold a piece of land to a spec-home developer for $25 million. And the McMackins are moving ahead with plans to complete their new house, though tariffs have been “the talk of the town,” Ron said.

“I do have a stock portfolio and it is down,” he said. “But I don’t let that affect what I’m doing. We’re very fortunate with resources.”

While Satter agrees with efforts to bring manufacturing back to the U.S., he said he has been blindsided by the extent of the trade war. “I’m not sure about how they’re rolling it out,” he said.

A handful of potential buyers have expressed interest in his $285 million listing, he said, but he realizes the prospective buyer pool is tiny. “There are going to be three or four people who ultimately show real interest and have the capacity to pull the trigger,” he said.

Ultimately, he said he isn’t too worried about the prospects for sale, since he can afford to sit on the property long-term.

Still, real-estate agents said Satter’s property and others may be priced too aggressively, even without tariffs.

British hedge-fund billionaire Chris Rokos is listing his 3-acre Manalapan estate for $150 million, more than triple what he paid for it in 2017. And real-estate investor Vivian Dimond recently cut the price of a Manalapan home by $14.5 million, to $64.5 million. It’s been on the market since September 2024.

For some Manalapan residents, home values are beside the point. Bob and Aileen Carlucci, for example, have no intention of moving.

“We look at each other and we say. ‘This is it,’” Bob said. “You can’t get anything better, we don’t believe—in this country, at least.”

OpenAI has shelved the planned launch of GPT-6.1 Astra after internal tests raised concerns about deception and agents acting beyond user authorization, according to The Wall Street Journal. The company says it will investigate the issues and strengthen safety measures before releasing future models.

OpenAI says it is scrapping the release of its next-generation AI model over safety concerns that researchers raised during internal testing, in one of the clearest signs so far that agent misbehavior could stymie the industry’s rapid progression.

The move follows a summer punctuated by reports of artificial-intelligence systems industrywide going rogue, and marks a rare case of a major AI developer ditching a new release because of safety concerns.

The company had planned to launch the model, known as GPT-6.1 Astra, in the coming days or weeks, aiming for an October debut. The model was more capable than the company’s previous models in completing challenging tasks from end-to-end without human assistance, as well as writing.

The company instead will focus on improving the safety of future models, which it expects to be even more capable.

Saachi Jain, OpenAI’s head of safety systems, said in an interview that GPT-6.1 Astra regressed in two areas. Compared with its predecessor, GPT-6 Astra, the model performed poorly on tests measuring alignment, or how well the model adheres to what humans would like it to do. Specifically, GPT-6.1 Astra showed higher levels of deception: It wasn’t always honest about telling users of the actions it did or didn’t take.

Another issue was what OpenAI calls “scope authorization,” meaning that GPT-6.1 Astra would push ahead on a task without asking the user for permission, and would at times reach for external tools and services even if it might be unsafe.

“For anything regarding safety and alignment, there’s a trade off,” Jain said. “You really do need to find what’s the right line between staying within scope, but also avoiding laziness in terms of how the model actually pursues tasks even when it hits friction.”

While GPT-6.1 Astra improved in areas such as “model laziness,” Jain said it didn’t quite meet OpenAI’s bar for safety and alignment, so the company decided not to launch the model publicly.

The announcement comes one day ahead of OpenAI’s annual developer conference in San Francisco. In the past, OpenAI has used the conference as an opportunity to launch new models and services that reduce costs for software developers—a segment the ChatGPT-maker competes with rival AI company Anthropic to win over.

In recent weeks, OpenAI and Anthropic have called on industry partners to slow down the development of cutting-edge AI models and invest in safety standards, noting they will temper the pace of their own internal AI progress.

OpenAI says it is working to investigate a range of agent security incidents that it has discovered in recent months, and address the safety issues underneath them. As part of the work, the company has implemented a new monitoring system to catch AI-agent misbehavior more quickly, and started requiring engineers to use stronger security guardrails for testing its AI systems.

Earlier this summer hundreds of OpenAI’s internal agents, which were tasked with completing a cybersecurity test, ended up hacking into the AI company Hugging Face. Since then, high-profile organizations such as the Australian government and United Nations discovered that OpenAI’s agents used similar, but less extensive, techniques to gain access to their websites.

Many of the publicly known agent-security incidents involved OpenAI’s internal AI models that were never slated for public release.

Last week, OpenAI said it paused training on its most capable AI models after an AI agent slipped through a gap in the company’s internet restrictions to query a public chatbot. The company said its new monitoring systems flagged the incident within 15 minutes, and training on these models remains paused.

GPT-6.1 Astra isn’t one of those models, but a different case, the company said.

“We want to make sure our model development is safe no matter whether that’s in the company, or when we ship it to users,” Jain said. “But when we ship it to users, we have an extremely high bar in terms of safety and alignment.”

While the company decided not to ship GPT-6.1 Astra, it hopes to use the same base model to do additional reinforcement learning runs, and create future generations of its GPT-6 models.

OpenAI plans to conduct several deep dives to identify the root cause of the problems identified in GPT-6.1 Astra, Jain said. The work includes ensuring that OpenAI’s reinforcement learning environments are rewarding the right type of behavior, Jain added, though she noted the company would investigate all stages of model development.

AI companies have begun to draw scrutiny from policymakers and public officials, who are paying attention to the rapid development of the technology. Later this week, a Senate subcommittee is holding a hearing with third party AI researchers titled, “Rogue AI: Securing the Homeland Against AI Agent Attacks.”

Florida Attorney General James Uthmeier, a Republican, sued OpenAI in June, claiming that the company and Chief Executive Sam Altman knowingly released an unsafe product and ignored warnings that it could harm users.

In a motion for temporary injunction filed Monday, Uthmeier sought to prevent OpenAI from developing new AI models without third-party approved safeguards, stop ChatGPT from soliciting user engagement and limit the company’s ability to advertise ChatGPT as safe.

Tech companies claim they “cannot stop barreling forward with their potentially civilization-ending endeavors unless they are forced to do so by the government,” Uthmeier said in the filing. “The Florida Attorney General is answering your cry for help.”

An OpenAI spokeswoman said that people want to know AI is being developed safely, “and that starts with what companies like ours do ourselves.”

“Governments have an important role to play in setting robust safety standards for AI, and we’re committed to working with Florida and other states on advancing pragmatic AI policies that apply to the entire AI industry—not just one company,” she said.
