Nvidia and SpaceX both forecast $1 trillion（約160兆円） in future revenue, but Nvidia's path is clearer and its stock appears better value for investors right now.

What happened: Nvidia predicted that revenue from its Blackwell platform and upcoming Vera Rubin system through 2027 would total $1 trillion（約160兆円）, while SpaceX founder Elon Musk said the company may deliver $1 trillion（約160兆円） in revenue by 2030. Nvidia's latest full-year revenue reached more than $215 billion（約34兆円）, with growth of 65%, while SpaceX's total revenue last year was $18 billion（約2.9兆円）.

Why it matters: Nvidia is the leader in AI chips (the graphics processing units that power AI tasks) and has a track record of sustained growth and customer demand for new product releases. SpaceX, by contrast, is in a phase of heavy capital investment—its AI business unit spent $12 billion（約1.9兆円） on capital expenditures last year—making it harder to see a clear path to $1 trillion（約160兆円） revenue within less than five years. For investors comparing the two, Nvidia's forecast rests on established market strength, while SpaceX's depends on unproven growth in its AI and connectivity businesses.

What to watch: Starlink (SpaceX's connectivity business) accounted for more than 60% of SpaceX's total revenue last year and is driving growth. SpaceX has also signed compute capacity contracts with Anthropic and Alphabet representing $26 billion（約4.2兆円） in annual revenue for SpaceX. Nvidia's stock trades at 23x forward earnings estimates, which the article considers reasonably priced.
