Mashable notes that as of Tuesday morning Trump has offered up no evidence that he followed through with his pledge to buy a Tesla vehicle. As for Musk, he's spent the day personally thanking his fans, such as conspiracy theorist Alex Jones, for voicing their support for Tesla on his social media platform X.

The automaker’s shares soared after Election Day as Elon Musk took a high-profile role as a Trump adviser. Now those gains have evaporated.
