OpenAI CEO Sam Altman selling his $49 million worth of property: Here’s why

OpenAI CEO Sam Altman, the man behind ChatGPT, is reportedly selling his lavish Hawaiian compound for $49 million, just a year after marrying his husband, Oliver Mulherin, on the property.

Located in Kailua-Kona on Hawaii’s Big Island, the oceanfront estate spans 21.8 acres and features 10 bedrooms and 11.5 bathrooms, spread across multiple buildings, including a main residence, a guest house, and a private beach bungalow.

The property, purchased in July 2021, is described by Realtor.com as a “refined island retreat,” offering sweeping views of Kailua Bay and the Pacific Ocean.

Inside, the estate features an open-concept design that blends indoor and outdoor living, complete with a movie theater, gourmet kitchen, breakfast bar, and several spacious lounging areas.

Outside, the lush grounds include palm-lined gardens, a private pool, and direct beach access, making it feel more like a resort than a private home.

While Altman hasn’t publicly shared the reason behind the sale, the timing comes as the billionaire continues to expand his business ventures, including his growing influence in artificial intelligence, venture capital, and biotech.

However, luxury comes with a cost: Realtor.com reports that the property’s 2025 tax bill alone will total $631,454.
