Archer Aviation (ACHR) stock experienced a significant surge on Monday, October 6th, 2025, climbing 7.30% to close at $12.41 following Friday’s impressive 12.67% jump. This rise is fueled by speculation about a potential partnership with Tesla, with social media buzz and cryptic videos from both companies sparking investor interest. While neither Archer nor Tesla has officially commented on the rumors, retail traders have eagerly jumped in, driving trading volume to over 48.7 million shares as investors await a potential announcement from Tesla scheduled for October 7th. The speculation stems from strategic logic: Tesla’s push into real-world AI applications and autonomous systems could complement Archer’s certified eVTOL aircraft and FAA momentum. This has led some analysts to believe that the collaboration will be significant, with Elon Musk even emphasizing drone technology’s importance in July.
