Tesla, Inc. (TSLA): Who It Depends On
Tesla's biggest dependency is on battery cells, sourcing them from multiple partners across the US, Japan, Korea, and China rather than relying on any single supplier exclusively. On the other side of the business, Tesla's actual car-buying customer base is millions of individual consumers with no real concentration - so the "customers" side of this page instead looks at Tesla's growing business-to-business relationships, like other automakers now paying to use its Supercharger network.

Customer concentration
Tesla's core vehicle sales go to millions of individual consumers, which is inherently non-concentrated - a genuine strength, not a bottleneck. Instead, the chart below shows Tesla's most notable business-to-business relationships: other automakers that have adopted Tesla's NACS charging standard and pay to use its Supercharger network, plus historical regulatory-credit buyers.
