The SpaceX (NASDAQ: SPCX) IPO has captured enormous investor attention, with many focused on the company’s future growth potential in the space industry.
However, several established companies already have well-defined and bright futures that may offer more reliable long-term returns for investors.
The cloud computing sector continues to benefit from surging demand driven by artificial intelligence, making it one of the most compelling long-term investment themes available today.
The big three cloud providers, Amazon (NASDAQ: AMZN), Microsoft (NASDAQ: MSFT), and Alphabet (NASDAQ: GOOG)(NASDAQ: GOOGL), dominate this space through Amazon Web Services, Microsoft Azure, and Google Cloud respectively.
Cloud computing operates on a straightforward business model: companies build data centers, install computing equipment, and rent out that capacity to clients who need scalable resources.
AI start-ups and enterprises alike are increasingly turning to cloud platforms for the computing power they need, creating a powerful and sustained demand cycle for all three providers.
All three companies are spending heavily on infrastructure this year, with the big four AI hyperscalers, including Meta Platforms (NASDAQ: META), estimated to spend around $650 billion on data center capital expenditures in 2026.
Nvidia (NASDAQ: NVDA), a major computing equipment supplier, estimated that this figure would exceed $1 trillion the following year, signaling massive ongoing growth ahead for the sector.
Amazon CEO Andy Jassy noted in his annual shareholder letter that the faster a cloud company grows, the more it must spend to sustain and capture that growth.
With record-setting demand and build-outs currently underway, revenue across all three cloud giants is expected to skyrocket over the next several years.
When valuing companies in a heavy capital expenditure cycle, operating cash flow offers a cleaner picture by stripping out one-time effects and focusing on core cash generation.
From that standpoint, Amazon and Microsoft both look historically cheap, while Alphabet remains within a reasonable valuation range relative to historical norms.
SpaceX generated $6.6 billion in adjusted EBITDA in 2025, and dividing its current market cap of $2.5 trillion by that figure yields a price-to-adjusted EBITDA ratio of 379.
That elevated ratio stands in stark contrast to where Amazon, Microsoft, and Alphabet are currently trading, suggesting SpaceX must grow significantly into its valuation before delivering further upside.
For long-term investors seeking established growth at a reasonable price, the three cloud titans present a far more compelling case than the heavily priced SpaceX offering.
