One Mission Bay: the median listing sold in 3 days this year, and 13 of 16 went into contract inside two weeks
Every 2026 closing at One Mission Bay, with eight paired resales
Sixteen closings at 1000 3rd Street and 110 Channel through October 15, against 12 in the 2025 window. Median sale $1,474,000, the building's highest annual figure on record; price per square foot $1,328, under the 2019 high of $1,452. OpenAI's Third Street buildings are across the street.
One Mission Bay is the fastest-selling building in this series by a wide margin. The median MLS-listed sale at 1000 3rd Street went into contract in three days this year. Thirteen of 16 listed sales went under contract inside two weeks. In the 2025 window the median was 23 days and four of eleven made the two-week mark. Six of this year's sales — #812, #1305, #801, #806, #1005, 110 Channel #320 — recorded zero days on market, which on this MLS means they were under contract on the day they listed.
Sixteen closings through October 15, against 12, on $22.4 million against $15.8 million. The year-to-date median sale is $1,474,000, the highest annual median in the building's record (2025 full year: $1,244,000; the previous high was $1,362,500 in 2022). The median price per square foot is $1,328 against $1,220, up 9 percent, and still 8.5 percent under the building's 2019 figure of $1,452.
Every bedroom size moved the same direction. One-bedrooms: $938,000 to $1,049,000. Two-bedrooms, the bulk of the building: $1,488,000 to $1,602,500, $1,258 to $1,328 a foot. The one three-bedroom, #811 at 1,458 square feet, closed at $2,360,000 on October 9, the year's high, at $1,619 a foot.
Eight paired resales are on record, five above the prior price and three below. The widest gain is 110 Channel #327, bought from the developer in November 2017 for $983,500 and sold in July for $1,100,000. The widest loss is 110 Channel #312, a 508-square-foot studio bought in August 2021 for $785,000 and sold for $700,000. Three units bought from the developer in the November 2017 sell-out resold this year at between minus 0.5 and plus 2.9 percent — nine years, roughly flat, before costs.
The 2017 row in the year-by-year table, 174 closings, is that developer sell-out and not a resale market.

Across Third Street from OpenAI
One Mission Bay faces Third Street at Channel. OpenAI's 1455 and 1515 Third Street, subleased from Uber, are directly across the street; 550 Terry Francois is two blocks east and the Exchange at 1800 Owens three blocks south. Together they put OpenAI past a million square feet in Mission Bay (The Real Deal; SF Standard). CBRE recorded Mission Bay office asking rents near $131 a foot in Q3 2026, an all-time high and up 49.8 percent in a year; neighborhood vacancy fell from 41.2 percent at the start of 2024 to 13.2 percent at the start of 2026 (SF Examiner). No other submarket in the city moved that far.
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.
