Steve Hafner, co-founder and CEO of travel-search platform Kayak, has listed his ultra-luxurious penthouse on Miami’s exclusive Fisher Island for a staggering $85 million. The asking price is more than double the $40 million Hafner and his wife, Staci, paid for the unfinished space in 2021. Over the past few years, the couple customized the approximately 10,200-square-foot residence into a five-bedroom, high-end showpiece.
The decision to sell the Fisher Island penthouse follows their recent purchase of another luxury residence—a $24 million penthouse in South Beach. According to Hafner, both homes offered compelling advantages, but the couple ultimately chose to stay in South Beach. The Fisher Island property, however, is positioned to make waves in Miami’s booming high-end real estate market.
Miami’s luxury housing segment, particularly in exclusive enclaves like Fisher Island, has seen exceptional growth. In the fourth quarter of 2024, median sale prices on Fisher Island surged by nearly 65% year-over-year. Sales volumes rose by 60% during the same period, underscoring the strong demand for high-end, oceanfront properties in the region.
Hafner’s penthouse now ranks among the most prestigious listings in Miami. While the city’s current record for a condo sale stands at $120 million—achieved by a penthouse at the Shore Club Private Collection—Hafner’s $85 million listing is in close competition. It reflects broader trends in the luxury market, where customized, move-in-ready properties command top dollar from ultra-wealthy buyers seeking exclusivity, privacy, and access to elite amenities.
Fisher Island, accessible only by boat or ferry, has long attracted high-net-worth individuals due to its seclusion and premium offerings. As Miami continues to evolve into a global luxury real estate hub, trophy properties like Hafner’s are increasingly in demand, both for personal use and as high-yield investments.
With limited inventory at the top end of the market and strong interest from domestic and international buyers, Miami’s luxury sector shows no signs of slowing. Hafner’s listing highlights this momentum, capturing the appeal of custom living in one of America’s most exclusive neighborhoods.
