Tesla ( TSLA 0.04%) is one of the world's leading electric vehicle (EV) manufacturers, but many analysts believe the company's true value lies in its futuristic product platforms like the autonomous robotaxi and Optimus humanoid robot. In fact, CEO Elon Musk believes those products will make Tesla the largest company in the world one day.

Tesla Inc. is in a sales slump, with deliveries of its electric vehicles on track to decline for the second full year in a row.

The electric-vehicle maker has an aging lineup and slumping sales, but its CEO has shifted his focus to robotaxis and robots.
