Tesla and Jeff Bezos's stealth AI startup Project Prometheus are reportedly leasing space on the same West Oakland industrial campus at 1960 Mandela Parkway. Neither has confirmed it, no Oakland permit is on file, and the square-footage figures rest on uneven sourcing.

Two of the most heavily capitalized names in tech are reportedly signing leases on the same West Oakland industrial block — and as of Thursday, neither has said so out loud.

The site is American Steel Blocks, a renovated multi-tenant manufacturing complex of roughly 440,000 rentable square feet at 1960 Mandela Parkway, about a mile from the Port of Oakland with Union Pacific rail alongside. The reported tenants: Tesla, and Jeff Bezos's stealth physical-AI startup, Project Prometheus.

The Prometheus leg is better documented. Public radio station KALW reported Aug. 13, under a Gabriel Lopez byline, that the San Francisco Business Times had reported the AI company "recently signed a lease at 1960 Mandela Parkway" — attributing the deal to the Business Times, not a social post. Trade outlets The Registry and The Real Deal put the footprint near 100,000 square feet; KALW cited no number, so treat the six-figure figure as trade-press reporting, not a filing. It fits the company's stated hunt: as of March, per the SF Standard, Prometheus — co-led by Bezos and Vik Bajaj, and reported by TechCrunch in June to have raised $12 billion — was seeking 60,000 to 100,000 square feet of industrial space, atop 30,000 it already holds at 101 Mission Street in San Francisco.

The Tesla leg is thinner. The 40,000-square-foot figure traces to real-estate writer S.E. Robinson Jr. (@SERobinsonJr), who posted it to X this week. KALW independently lists Tesla among the campus's tenants — corroborating that Tesla is there, but not the square footage, the use, or the terms. Tesla has issued no statement, press release, or SEC filing; what it would build, if anything, is undisclosed.

Here is the ground that isn't moving. The landlord is ScanlanKemperBard, the Portland firm that bought the 14-acre American Steel and Peralta Street portfolio for $82.5 million in 2021, per its own announcement. Its public tenant directory names neither company — a reminder that both tenancies still rest on press reports, not signed-and-published confirmation. No tenant-improvement or use permit for either company appears in Oakland's planning records this desk could locate.

The clustering is the story: two of tech's biggest balance sheets converging on one West Oakland lot is the kind of industrial spillover from a saturated, expensive San Francisco that brokers have long expected — finally showing up as reported square footage rather than a slide deck.

What to watch: a use or tenant-improvement permit filed at 1960 Mandela Parkway — the one document that would pin down what Tesla intends and turn a cluster of leases into a cluster of operations. Until then, the leases are reported, the companies are silent, and the paperwork hasn't dropped.
