Anthropic doubles down downtown

Anthropic’s commitment covers 300 Howard, a 25‑story tower listed at 466,000 square feet, plus the adjacent historic 342 Howard (about 18,000 square feet) for a combined footprint in the mid‑480,000s. (businesswire.com) (businesswire.com) Multiple trade reports say the downtown deal was struck as a long‑term, roughly 13‑year lease, marking one of the larger multi‑year commitments to SF office product this cycle. (sfist.com) (sfist.com) Anthropic already occupied substantial nearby blocks prior to this move—about 250,000 square feet at 500 Howard and roughly 100,000 square feet at 505 Howard—creating a contiguous campus opportunity along the Howard corridor. (therealdeal.com) (therealdeal.com) The seller/owner team on 300/342 Howard is a DivcoWest–Blackstone Real Estate joint venture that bought the asset last April for about $111.3 million before the Anthropic deal was announced. (therealdeal.com) (therealdeal.com) JLL handled representation in the negotiations with ownership’s team led by Chris Roeder, Ted Davies and Carlye Parker while Felipe Gomez‑Kraus and John Diepenbrock of JLL represented Anthropic. (businesswire.com) (businesswire.com) San Francisco Business Journal reporting indicates Anthropic is already scouting additional contiguous block(s) nearby, a follow‑on demand pattern that is forcing tenants and brokers to prioritize adjacent floors and swing‑space options. (bizjournals.com) (bizjournals.com) Anthropic told owners it has more than 1,300 Bay Area employees as it consolidates into larger downtown footprints, and local coverage notes the company may vacate roughly 230,000 square feet at its existing 500 Howard location as part of the transition.
