Where is xAI headquartered?
xAI is headquartered in Palo Alto, California, in the Stanford Research Park at 1450 Page Mill Road, which serves as its research and corporate hub in the San Francisco Bay Area; it expanded with additional Page Mill Road leases in early 2026. Its physical center of gravity, however, is the Colossus supercomputer complex in Memphis, Tennessee, with a second gigawatt-scale facility (Colossus 2) in Southaven, Mississippi. Since the February 2026 SpaceX merger, xAI's footprint is increasingly intertwined with SpaceX's facilities.

Where is xAI's headquarters?
xAI's corporate headquarters is in Palo Alto, California, at 1450 Page Mill Road in the Stanford Research Park, in the heart of Silicon Valley. This is where much of its research, engineering, and corporate functions are based, and in early 2026 it added adjacent Page Mill Road space (including ~100,000 sq ft at 1510 Page Mill Road) as it grew.
After the February 2026 SpaceX acquisition, xAI operates as SpaceX's AI division, so its corporate identity is increasingly blended with SpaceX (headquartered in Starbase, Texas). The Palo Alto site remains xAI's primary research hub.
What other offices does xAI have?
xAI's most consequential locations are its data centers, not traditional offices. Colossus 1 sits in Memphis, Tennessee (Riverport Road / Tulane Road), and Colossus 2 is in Southaven, Mississippi, just across the state line, under a $20B-plus commitment targeting roughly 2 gigawatts of compute and powered substantially by on-site gas turbines.
These sites host the bulk of xAI's operational headcount, including thousands of data-center, annotation, and operations staff, alongside the Bay Area research presence. The Memphis/Southaven cluster is effectively xAI's largest operational hub by people and capital.
What xAI's office footprint means for territory planning
xAI splits cleanly into two go-to-market territories. The Bay Area (Palo Alto) is where research leadership, model teams, and corporate decision-makers cluster — the right region for executive ABM, exec dinners, and AI-research field events, on Pacific time.
The Mid-South (Memphis, TN and Southaven, MS) is where the infrastructure spend lives: power, cooling, networking, security, logistics, and data-center operations buyers, on Central time. If you sell infrastructure or industrial services, run field motions and local partnerships around the Memphis metro; if you sell research or developer tooling, focus on the Bay Area. Note that since the SpaceX merger, some decisions now route through Texas (Starbase) as well.
