Tesla capex misses by $3.2 billion

Tesla reported Q3 revenue of $28.05 billion, slightly short of the $28.13 billion consensus, but the capital expenditure figure drew the sharper focus. The company spent $4.73 billion in the quarter against a projected $7.96 billion, a gap of more than $3 billion. On the earnings call, Elon Musk said spending would become “more meaningful next year” and reach “tens of billions” in 2028. Ryan Lee of Direxion told Reuters the underspend signals a less aggressive posture in the AI infrastructure race than markets had priced.

The $80,000 to $81,500 zone, which holds the cost basis for US spot Bitcoin ETFs, now acts as key support.
