Presidio Heights is proving to be a center of gravity as luxury housing supply in San Francisco vanishes and the city’s well-to-do scramble to claim their slice of the artificial intelligence industry’s nerve center.

On the same day last week, the city recorded two home sales in the wealthy neighborhood for $9.2 million and $10 million.

The first reflected the fortunes being created by the AI industry. Venture capitalist Kenneth Wallace and his wife, Moriah Lewis, sold their five-bed, 4,755-square-foot home at 3875 Clay Street for $9.2 million. Josh McAdam of Sotheby’s International Realty represented the seller. The property last sold for $6.8 million in 2021. 

The buyer initially kept their name hidden behind a Delaware-incorporated LLC named after the property’s address. However, according to public loan documents, the LLC is managed by Daniel Berrios and Kimberly Tan, a couple in their early 30s who graduated from Stanford into the San Francisco tech sector. Berrios works on special projects at OpenAI, and Tan is an investing partner with blue chip venture capital firm Andreessen Horowitz. Wells Fargo Bank provided a $5.4 million loan for the purchase.

Ten blocks east, sellers Herbert and Shwu-Ling Wei sold their six-bed, 5,000 square-foot home at 2881 Jackson Street for $10 million. Kyle Vineyard, a CPA with Realize Tax Advisors, is the trustee of the buyer, RKLA Trust. It is unclear whether Vineyard’s involvement is purely professional or if he’s connected to the trust.

The home last sold in 2014 for $6.8 million.

Presidio Heights, the neighborhood that runs along Presidio Park at San Francisco’s north end, has experienced a hot streak during the first half of 2026. Earlier this month, two mansions in the area sold for a combined $32 million, marking the fourth and fifth sales this year to eclipse $10 million. There were seven sales above that benchmark in Presidio Heights in all of 2025, according to Zillow data.

San Francisco, where the median home sale fetches $2.2 million, is dealing with its own version of champagne problems: a mansion shortage. The AI boom has attracted a wave of high-paid employees, apparently leaving the city with more millionaires than mansions. Steep capital gains taxes have made some mansion owners hesitant to let go of their property. Others are holding out for the expected spike in luxury home demand following Anthropic and OpenAI’s initial public offerings of stock, which are expected to come later this year.

DENVER — The biennial Transplant Games wrapped up in Denver this week, bringing hundreds of organ donors and recipients together to compete in everything from cycling and swimming to darts and trivia at venues all over the city.

In fact, the games set a Guinness World Record for most living donors and recipients in one place at one time, with 966 gathering at the Colorado Convention Center.

Angela Laino, who used to live in Boulder, came back to Colorado to compete in the games. She donated a kidney to a stranger in January before running in the 5K event.

“I’m what they call a non-directed living kidney donor, which means that I don’t know who my recipient was,” she explained. “So I just said, ‘Whoever needs my kidney, I’m sure they’ll find the best match for it.’”

Transplant Games in Denver sets Guinness World Record

Laino said she was inspired by her job, working “on and off” as a dialysis social worker for 17 years.

“I really saw the challenges that my patients faced,” she said. “I saw what they had to go through to get on the [transplant] wait list… I know what transplant means for people. I’ve seen it firsthand. And to be able to see them come out here, compete, they’re doing basketball, they’re doing badminton, they’re swimming, they’re cycling, they’re running. They are living their full lives, and that’s really what transplant can do for people.”

Laino said the games unite the community and show off its resilience.

“When you go through the transplant process, sometimes you feel alone, you feel like you’re the only one going through this,” Laino said. “And then you come to an event like this and you literally see thousands of people. You see recipients, living donors, donor families coming together for the same cause. It’s really inspiring, because it really helps to get the word out, spread awareness about the organ shortage, and it shows people what recipients and donors can do after they have the surgery.”

Dr. Michael O’Shea — a nephrologist, a doctor who cares for kidney disease patients and the kidneys in general — agrees. But he said more needs to be down to support patients and spread the word about the need for organ donations.

The National Kidney Foundation estimates 37 million Americans have Chronic Kidney Disease, which occurs when kidneys cannot filter the blood properly, leading to serious health issues. Because symptoms can be minimal in early stages of the disease, many patients don’t realize they have it.

“I think education about kidney transplant, both on the patient side as well as on the potential donor side, could be markedly ramped up and improved,” Dr. O’Shea said. “It’s struggles with communication between transplant centers, patients, and community nephrologists. No one’s fault. It’s just a very complicated delivery system.”

In the case of kidneys, people can become diseased donors — who register to donate in the case of their sudden death — or living donors, who donate one kidney will relying on the other. Dr. O’Shea said both are critical to meet nationwide demand for life-saving transplants, though the living donations tend to have a longer lifespan — around roughly 20 years — for recipients.

“A number of folks get transplanted every year off this list,” O’Shea explained. “It is also true that a greater number of folks get added to the list every year.”

To register to become a deceased donor, Coloradans can visit their local Department of Motor Vehicles office or visit registerme.org.

O’Shea said those considering living donations face an “exceedingly small” medical risk for end-stage kidney disease, but should consult with their doctor about the decision.

Even as the games leave Denver, a reminder will stick around through the summer. Denver Parks and Recreation, the Downtown Denver Partnership and DaVita have partnered to set up a basketball court in Skyline Park near Arapahoe and 17th Streets, in order to keep the spirit of the games alive and honor the resilience of organ donors, recipients and their families.
