SpaceX and Tesla merger: Could a $10,000 investment grow to $20,000 by 2030 or are investors paying too much?

SpaceX brings 161% quarterly revenue growth, while Tesla contributes more than $100 billion in annual sales. But both stocks carry high valuations. For investors considering $10,000, the biggest question is whether future growth can justify today's expensive share prices.
