ACHR stock rose after completing FAA certification phase 3 and targeting 2024 commercial launch and 2028 Olympics debut.
Shares of Archer Aviation (ACHR) climbed 18.6% in May, driven by regulatory advancements and defense sector momentum. The company completed phase 3 of FAA certification for its Midnight eVTOL aircraft, leaving only phase 4 before commercial operations can begin.

Defense partnerships, including work with Anduril, have likely contributed to investor optimism amid broader sector strength in 2026.
