131 Missouri, the nine-unit 2017 building on the north slope of Potrero Hill: one closing this year, a two-bedroom-plus-den listed at $1,995,000 and sold at $2,265,000 in eight days, $1,546 a foot, the building's high

131 Missouri's one sale this year set its per-foot high by a wide margin. One condominium closed between January 1 and October 15, 2026, against one in the same window of 2025; $2,265,000 of volume against $1,800,000. The price per square foot is $1,546, against $1,143 on last year's sale and $1,333 on the one 2021 sale; the record on this site holds three closings in all.

#301, a 1,465-square-foot two-bedroom with a den, a Miele kitchen, a gas fireplace, a private terrace and an assigned space with Level 2 charging, was listed on May 28 at $1,995,000, went pending on June 12 and closed at $2,265,000 on June 26 after eight days, 13.5 percent over the ask; its dues run $926 a month; the listing record shows it sold new in July 2019 at exactly its $1,995,000 list, a pairing the site's record does not hold (Redfin; MLSListings).

The building dates from 2017, nine units with an elevator and a panoramic roof deck on a 7,500-square-foot lot on Missouri between Mariposa and 17th; the building record on this site lists two units (Redfin street index; MLSListings).

2026 so far, against the same window in 2025

Closings at 131 Missouri St between January 1 and October 15, 2026, set against January 1 to October 15, 2025. Days on market is median days from listing to contract on MLS-listed sales; "under 15 days" counts how many of those went into contract inside two weeks.

Missouri Street, between Mariposa and 17th

Across the street, 146 Missouri, a 1913 Queen Anne by Paul Capurro destroyed by fire and last sold in 2022 for about $1.3 million, has permits filed for demolition and a four-story building of two four-bedroom homes with a private elevator, reported in March 2025, half a block from Bottom of the Hill and two blocks from Jackson Playground (SF YIMBY, Mar 2025; SF YIMBY, May 2024). The listing's shops and restaurants are on 18th Street, a block up the hill, and 210 Mississippi at Mariposa offered a 3,573-square-foot creative office at $6,800 a month in May 2026 (Redfin; LoopNet brochure).

The nearest AI office is Resolve AI's top floor at 350 Rhode Island, the converted recycling plant about four blocks west, reported in August 2025; the office figures in the paragraphs below describe SoMa (CoStar).

The timetable that every South of Market building now sits inside is the public-offering calendar. Anthropic filed a confidential draft registration with the SEC on June 1, 2026, a week after a funding round that set its valuation at $965 billion (TechCrunch). As of this week the Standard reports the Anthropic listing has been pushed to November, after the midterms, that OpenAI's has moved to 2027, and that Anthropic is weighing a lockup longer than the usual six months (SF Standard). The same piece carries a Redfin estimate that current and former OpenAI and Anthropic employees could in theory buy close to a third of the metro area's homes with their proceeds, and the counter-argument from UC Berkeley's Enrico Moretti and the Bay Area Council's Jeff Bellisario that the money is concentrated in fewer hands than past booms and that these firms create fewer jobs per dollar because so much goes to data centers rather than headcount. The record in this report ends on October 15. None of it reflects a single share that has been sold.

Two citywide facts frame every building figure here. First, the office recovery is lopsided: CBRE put Q3 2026 vacancy at 27.7 percent citywide, down 6.6 points in a year, but Avison Young splits that into roughly 12 percent for Class A and north of 31 percent for Class B, and a Presidio Bay executive told Bisnow the headline number is misleading for that reason (Bisnow). Second, the condo market is still digging out: the Chronicle's May analysis found that only eight Bay Area ZIP codes showed inflation-adjusted condo gains over the year, all of them in San Francisco, and that Noe Valley's typical condo remained close to $400,000 below its 2019 level in real terms (SF Chronicle).

How this was counted

Two records feed this review. The MLS layer is one row per listing and carries days on market and square footage. The county layer reaches back further and catches transfers that never listed, but records the same closing once per data source, so the two were merged on unit, date and price and each closing kept once. Below-market-rate units and transfers under $300,000 are listed but excluded from every median. "Same window" means January 1 to October 15 of each year. Nothing here is a valuation of any unit, and nothing here is advice.
