OpenAI CEO and ChatGPT creator Sam Altman<\/a> has taken his incredible Hawaii estate<\/a> off the market, nine months after listing it for $49 million\u2014and just two weeks after his primary residence in San Francisco was targeted in two separate attacks<\/a>.<\/p>\n

Altman, 41, quietly purchased the property in an off-market deal back in July 2021; however, his ownership of the extraordinary beachfront dwelling was not made public until November 2023.<\/p>\n

The following January, the estate, which occupies nearly 22 acres, served as the venue for the tech mogul’s secret wedding to his longtime partner, Oliver Mulherin.<\/p>\n

At the time, Altman neglected to share any details about the ceremony\u2014however, the listing photos for his Hawaii<\/a> compound revealed the property as the location of the intimate event, showcasing the same palm tree-filled background that featured in the images taken during his wedding.<\/p>\n

The billionaire, who is notoriously private and shares little to no details about his private life, has not revealed his reasons for listing the compound, which is located in Kailua-Kona<\/a> on the Big Island and sits next to a reconstruction of the temple of\u00a0King Kamehamela I, the first ruler of the Kingdom of Hawaii.<\/p>\n

However, it is one of numerous dwellings in his property portfolio\u2014which includes a $65 million collection of homes in San Francisco, where OpenAI has been based since its inception, as well as a ranch in Napa, CA<\/a>.<\/p>\n

Altman’s Hawaii residence is understood to have served primarily as a vacation retreat, offering a vast number of amenities that would traditionally be found at a five-star resort, including a heated gunite pool with a built-in spa. There is also a full sports court for basketball and tennis, and a private marina that has been outfitted with a man-made beach, effectively turning it into a second swimming pool.<\/p>\n

Set on a staggering 21.8 acres of “secluded luxury,” the property features a total of 10 bedrooms and 11.5 bathrooms, which are split between a main residence and a guesthouse. When it was listed, the home was the second most expensive Hawaii property on the market at that time.<\/p>\n

In the five years since he bought the property, which was previously owned by Microsoft co-founder\u00a0Paul Allen, Altman has made many upgrades and updates, per the listing\u2014which drew particular attention to the “advanced security systems” that had been put in place to “guarantee peace and discretion.”<\/p>\n

Certainly, those who wish to shy away from prying eyes could happily remain behind the walls of the compound with little reason to venture outside\u2014thanks to the many features that the property has to offer.<\/p>\n

Inside, the main residence boasts a movie theater, several enormous indoor\/outdoor living spaces, and a sizable kitchen with ample room for guests to dine at the breakfast bar.<\/p>\n

The estate is situated on the water front, providing instant access to the beach, where many different water sports can be enjoyed, with the listing images capturing two people heading out to paddleboard from the private marina.<\/p>\n

The listing also included an image of a helicopter landing on the grounds, revealing a special plot of flat land ideal for use as a helipad.<\/p>\n

Additionally, there are multiple entertaining areas located within the grounds of the home, including a sheltered lanai with a large dining room table, where Altman and Mulherin were pictured dining with guests after their wedding ceremony.<\/p>\n

“Every detail, from oceanfront views to exclusive amenities is crafted for a life of privacy and elegance,” the description noted.<\/p>\n

“Located in one of Hawaii’s most prestigious settings, this estate embodies a blend of luxury and natural beauty. Expansive living spaces, lush\u00a0outdoor areas, and sweeping views of Kailua Bay and the Pacific Ocean, create a refined island experience.”<\/p>\n

The true size of the property was reflected at the end of the listing, which made mention of Hawaii’s unique tax map key (TMK), a system used in the state to identify property ownership, assess taxes, and track legal boundaries.<\/p>\n

Each TMK in the state is made up of five numbers that pinpoint the property’s exact location\u2014however, in the case of Altman’s Hawaii estate, the property incorporates six TMKs, demonstrating its impressive size.<\/p>\n

This does, however, mean the property comes complete with sky-high taxes, which cost Altman a staggering $631,454 in 2025 alone, according to\u00a0Realtor.com\u00ae<\/a> data.<\/p>\n

It’s currently unclear why Altman has chosen to remove the listing for his Hawaii property\u2014however, it may be that his focus is currently elsewhere, particularly in the wake of the two attacks that were targeted at his primary residence in April.<\/p>\n

According to a statement issued\u00a0by OpenAI, the parent company of ChatGPT, the first attack took place in the early morning on April 10.<\/p>\n

“Early this morning, someone threw a Molotov cocktail at Sam Altman’s home and also made threats at our San Francisco headquarters,” the statement read.<\/p>\n

“Thankfully, no one was hurt. We deeply appreciate how quickly [the San Francisco Police Department] responded and the support from the city in helping keep our employees safe. The individual is in custody, and we’re assisting law enforcement with their investigation.”<\/p>\n

The San Francisco Police Department\u00a0confirmed to NBC News<\/a>\u00a0in a separate statement that officers had responded to “a fire investigation” at an address in the North Beach neighborhood of the city at around 4:12 a.m. local time.<\/p>\n

Less than an hour later, police responded to reports of “an unknown male threatening to burn down” a corporate building on the street where OpenAI’s headquarters is located.\u00a0It’s understood that he was identified by officers as the same man who had been seen near Altman’s private home.<\/p>\n

That suspect, who was identified as Daniel Alejandro Moreno-Gama, has since been charged with attempted murder and attempted arson. During a court appearance in San Francisco on May 5, he pled not guilty to all charges against him.<\/p>\n

Two days after the suspected Molotov cocktail incident, the San Francisco Police Department issued a statement<\/a>\u00a0confirming that two suspects\u2014Amanda Tom, 25, and\u00a0Muhamad Tarik Hussein, 23\u2014had been taken into custody after officers responded to “a suspicious occurrence of possible shots fired” near Altman’s home.<\/p>\n

“Through the course of the investigation, officers learned that a vehicle with two occupants drove past a residence around the time of the possible shooting,” the SFPD noted. “Investigators assigned to the Special Investigation Division (SID) took over the investigation and determined the vehicle belonged to 25-year-old Amanda Tom of San Francisco.<\/p>\n

“Officers responded to the 2000 block of Taylor Street and detained Tom and 23-year-old Muhamad Tarik Hussein without incident. A search warrant for the residence was conducted, and officers located and seized three firearms. Investigators developed probable cause to arrest Amanda Tom and Muhamad Hussein.”<\/p>\n

Both Tom and Hussein were then taken to the San Francisco County Jail, where they were booked for negligent discharge.<\/p>\n

Altman owns multiple properties in San Francisco, all of which are located on the same street in the city’s Russian Hill neighborhood. He purchased the compound for a total of $65.4 million over several years.<\/p>\n

He bought the first of the four dwellings in 2020 for $27 million\u2014and later became embroiled in a bitter and lengthy legal battle with its developer,\u00a0Greg Malin, and his company, Troon Pacific, over claims that the home was “plagued by shoddy construction.”<\/p>\n

Altman, who filed the 2024 lawsuit via the LLC through which he purchased the 1907 home, claimed in legal documents seen by\u00a0Realtor.com\u00ae<\/a>\u00a0that Malin’s company carried out “substandard work” on the home to save money during its multiyear renovation project.<\/p>\n

The AI mogul then snapped up three adjacent homes on the same block in January 2025, paying $12.8 million for each of the dwellings, according to records.<\/p>\n

Those three homes are all registered to the same LLC, which is managed by Altman’s cousin,\u00a0Jennifer Serralta, who also oversees the LLCs connected to his other property purchases.<\/p>\n

Much like the OpenAI CEO’s original Russian Hill home, the properties were all built in the early 1900s and had previously been purchased together to form a large compound by their previous owners in 1994, records indicate.<\/p>\n

When he is not spending time in San Francisco, however, Altman can be found enjoying his stunning ranch in Napa, CA, where\u2014he previously told the\u00a0New York<\/a>\u00a0Times\u2014he and Mulherin spend most of their weekends.<\/p>\n

Altman invited a Times reporter,\u00a0Cade Metz, to visit the home in 2023, with the resulting article noting that the 25-year-old home had been remodeled to “look both folksy and contemporary.”<\/p>\n

The report noted that Altman, who is a vegetarian, and his then-partner were raising beef cattle on the land surrounding the home, which was tended to by farmhands, who also grew wine grapes on the property.<\/p>\n

According to records, the ranch\u2014which spans a staggering 950 acres\u2014was purchased for $15.7 million in 2020, having initially been listed for $25.5 million.<\/p>\n

Property records show that the ranch, named Green Valley Ranch, was purchased through an LLC that Altman’s cousin, Serralta, is also the manager of.<\/p>\n

At the time of the sale, reports revealed that the ranch had previously been owned by a group of eight men, who had used the property “communally” for 42 years.<\/p>\n","protected":false},"excerpt":{"rendered":"OpenAI CEO and ChatGPT creator Sam Altman has taken his incredible Hawaii estate off the market, nine months…\n","protected":false},"author":2,"featured_media":32586,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[2683,20899,20902,20898,157,20900,370,969,20901],"class_list":{"0":"post-32585","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-openai","8":"tag-hawaii","9":"tag-kingdom-of-hawaii","10":"tag-muhamad-tarik-hussein","11":"tag-oliver-mulherin","12":"tag-openai","13":"tag-primary-residence","14":"tag-sam-altman","15":"tag-san-francisco","16":"tag-secret-wedding"},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts\/32585","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/comments?post=32585"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts\/32585\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/media\/32586"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/media?parent=32585"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/categories?post=32585"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/tags?post=32585"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
