Reuters+1 As of Thursday morning, Tesla shares were indicated around $467, reflecting a roughly 4.6% drop from the prior close. That pullback came just after TSLA touched an all-time high near $495 during Wednesday’s trading, before reversing lower. AP News+1 Below is what’s driving Tesla stock

Dec. 18, 2025 — MARA Holdings, Inc.
