Tesla's stock rose to more than $1,000 a share for the very first time Wednesday, lifting its valuation above $190 billion.
Why it matters: Given its pace of growth this year, Tesla is now closing in on car industry leader Toyota's $216 billion, according to the WSJ.
The company's market cap has risen by nearly $40 billion in the last month and by $70 billion in the last three months.
What happened: The price jump followed news of an internal memo from CEO Elon Musk that it's "time to go all out" and bring its long-planned semitruck into "volume production."
Of note: Musk's note about Tesla's electric trucks follows a surge in the stock price of electric truck manufacturer Nikola, which has tripled its price since it began trading last week.
The jump pushed the company's market cap briefly above both Ford and Fiat Chrysler, despite the fact that Nikola hasn't sold a single vehicle.
