In Tesla's most recent quarter, their revenue for "Services & Other," which is where Supercharging lives, was $2,166M, while the cost of revenue for Services & Other was $2,037M. So, a gross profit of $129M on revenue of $2,166M or ~6% gross margin. This is in line with their previous statements that they run the Supercharging network at breakeven - although they don't seem to publicly break out SC-specific numbers from the Services & Other totals. There may be outlier locations, but overall Supercharging is not a big profit center for them. Maybe it'll improve with scale.
