Market insiderTesla is bigger than Ford.
Tesla's stock price is up almost 5% on Monday at $292 a share after the company reported blow-out delivery numbers for the first quarter.
Monday's gain has the electric car marker's market cap up to $47.77 billion, overtaking Ford's market cap of $44.70 billion.
Tesla said deliveries skyrocketed 69% year-over-year in the first quarter to a record 25,000 vehicles.
Deliveries were split pretty evenly between the Model S and newer Model X SUV. Tesla said it expects to deliver between 47,000 and 50,000 vehicles in the first half of 2017.
The move comes on the same day that Ford and GM stock are down on weak March sales numbers.
