- Meta offers a mature advertising engine and enormous user base, while SpaceX combines Starlink, rockets, and AI. The two stocks represent very different long-term bets.
Choosing between Meta Platforms Inc. (NASDAQ: META) and SpaceX (NASDAQ: SPCX) as a single stock to hold for decades comes down to two very different investment profiles. Meta already generates substantial revenue and cash from Facebook, Instagram, WhatsApp, and its broader advertising business. SpaceX is pursuing a much wider set of future markets, including satellite internet, launch services, AI computing and next-generation spacecraft.
The difference is visible in their financial profiles. Meta generated $60.8 billion of revenue in the second quarter of 2026, up 28% from a year earlier, while its Family of Apps reached 3.60 billion daily active people.
SpaceX, meanwhile, nearly doubled quarterly revenue to $7.8 billion in the second quarter, driven by Starlink and its emerging AI business, but it still reported a $541 million loss.
Meta Has the Established Cash Engine
Meta's biggest advantage in a decades-long holding scenario is that its core business is already highly profitable. Advertising generated $59.4 billion of Meta's $60.8 billion in Q2 revenue. The company also produced $31.9 billion in operating cash flow during the quarter, although free cash flow fell to just $784 million as spending on AI infrastructure surged.
That spending is becoming one of the central questions surrounding the stock. Meta expects 2026 capital expenditures of $130 billion to $145 billion, reflecting the enormous computing and data-center investment required for its AI strategy.
The company is nevertheless trying to turn that investment into additional businesses. Its Muse AI assistant has expanded into small-business applications, while Meta is building an enterprise AI operation that could eventually generate revenue beyond advertising.
Meta also has a distribution advantage that would be difficult for a new competitor to replicate. Billions of people already use its platforms, giving new AI products an existing audience rather than requiring the company to build one from scratch.
That combination makes Meta's long-term story relatively straightforward: maintain its advertising business while converting its enormous user base and AI infrastructure into additional sources of revenue.

SpaceX Offers More Future Markets, but More Execution Risk
SpaceX presents a very different proposition. The company went public in June at $135 per share, raising $75 billion at a valuation of roughly $1.77 trillion.
Its first public earnings report showed how quickly the business is expanding. Revenue reached $7.8 billion in Q2, compared with $4 billion a year earlier. Starlink contributed significantly to the increase, while SpaceX's AI business added nearly $2 billion of year-over-year growth.
SpaceX also expects a $100 billion annualized revenue run rate by December, according to Reuters. The company is simultaneously expanding Starlink, developing next-generation rockets and investing heavily in AI computing infrastructure. This creates substantially more potential business lines than Meta currently has.
Starlink can continue expanding satellite connectivity. SpaceX can potentially reduce launch costs through reusable rockets. Its AI infrastructure could become another significant source of revenue, while future spacecraft could open additional markets.
But the financial tradeoff is clear. SpaceX is spending heavily to pursue those opportunities. The company recorded more than $28 billion in capital expenditures during the first half of 2026, compared with about $7 billion during the same period a year earlier.
SpaceX's valuation also leaves investors paying for substantial future growth. Its IPO valuation was about $1.77 trillion despite the company having reported a loss in 2025. That makes the SpaceX investment case heavily dependent on the successful expansion of businesses that are still developing.
For a hypothetical investor holding one stock for decades, the choice therefore comes down to the type of exposure desired. Meta provides an established advertising business with billions of users and significant operating cash generation, while SpaceX provides exposure to Starlink, launch infrastructure, and AI alongside a much larger collection of long-term projects.
Neither business can guarantee decades of shareholder returns. Meta must prove that its enormous AI spending produces sufficient financial returns, while SpaceX must convert its aggressive investments into sustainable profits across several emerging businesses.
