What’s Better: SpaceX At $2T Or Google At $5T

What's Better: SpaceX At $2T Or Google At $5T?

Alphabet (GOOG) and SpaceX are both infrastructure companies. One monetizes the digital infrastructure the world already depends on. The other is trying to build the infrastructure the world may depend on next.

Alphabet generates more than $400 billion in annual revenue and roughly $130 billion in annual net income. The stock trades at about 22x trailing EBITDA. (valuation metrics for Alphabet) More importantly, it already sits at the center of the modern internet, controlling massive consumer traffic, global computing infrastructure, and some of the most deeply embedded digital platforms in daily life.

SpaceX, reportedly targeting a $1.75 trillion Nasdaq listing, generated an estimated $15.5 billion in revenue and $8 billion in EBITDA over the last year, driven primarily by Starlink. ^[1] At that valuation, the company would trade at over 200x trailing EBITDA.

And yet the market values the two companies only about 2.5x apart. That raises a deeper question: Is the market saying Alphabet is undervalued, or that SpaceX could eventually control infrastructure important enough to justify pricing that today looks extreme?

Why Alphabet's Moat Is Deeper Than It Looks

The original bear case around Alphabet was that AI could weaken its dominance in search. That thesis is increasingly difficult to sustain because Alphabet's advantage was never just model quality. It remains a distribution.

Search, Android, Chrome, YouTube, Maps, Gmail, Workspace, and Google Cloud together form one of the largest digital ecosystems ever assembled. Alphabet controls not just applications, but the distribution rails, user traffic, cloud infrastructure, and increasingly the compute stack underneath AI itself through TPUs and hyperscale data centers.

The 28x forward earnings multiple, a 35% premium to its five-year average, is backed by contracted numbers. The Google Cloud backlog stood at $462 billion at quarter-end, nearly doubling from $240 billion in a single quarter, with over $230 billion converting within 24 months. On May 19, Google and Blackstone (BX) announced a joint AI cloud venture delivering compute-as-a-service built on TPUs, with total investment potentially reaching $25 billion.

Alphabet also holds assets not yet captured in the multiple. Waymo is running a fully commercial ride-hail operation across ten U.S. cities with over 500,000 paid weekly rides. Alphabet also holds a roughly 6% equity stake in SpaceX. The main overhang is antitrust: the DOJ filed a notice of appeal in February 2026 on the search-monopoly ruling, and a separate ad tech case remains open.

SpaceX Is Pricing a Future That Hasn't Arrived Yet

SpaceX is a genuinely profitable industrial company. A 51% EBITDA margin on an aerospace and hardware business is exceptional. However, with the stock trading at over 218x trading EBITDA, the market is pricing in considerably more than what exists today.

Starlink, now exceeding 10 million global subscribers, is estimated to generate more than half of total revenue, with 2026 revenue projected to exceed $20 billion as direct-to-device capabilities expand. It is, in effect, a telecom business: recurring subscriber fees, government contracts, and utility-like revenue with meaningful growth still ahead.

The next phase is Starship, designed for complete two-stage reusability. Launch economics is a compounding moat. SpaceX cut costs from $15,600 per kilogram in 2008 to under $1,000 today, rendering most competitors uneconomical in the process. Full starship reusability targets below $100 per kilogram launch costs.

The most speculative and potentially most consequential element is orbital compute. The bottleneck for AI infrastructure is shifting from the GPUs provided by the likes of Nvidia (NVDA) to power and land. Every major hyperscaler is hitting grid congestion and permitting delays on Earth. The logic follows from a simple constraint: orbital infrastructure powered by unshielded solar bypasses both. In May 2026, Anthropic became the first external customer for SpaceX's Colossus supercomputer cluster.

Certainty vs. Optionality: What You're Actually Buying

Alphabet is priced on a scale that already exists. Its AI monetization, cloud backlog, and distribution advantages are visible in reported numbers today. Even the upside cases, Waymo, TPUs, Gemini, sit adjacent to businesses already generating enormous cash flow.

SpaceX is different. Investors are not valuing the current launch business or even Starlink alone. They are underwriting a future where SpaceX becomes foundational infrastructure for communications, logistics, defense, and potentially even AI compute itself.

That future is plausible. But much of it remains unproven. The distinction matters because infrastructure businesses compound differently depending on where they sit on the adoption curve. Alphabet is harvesting infrastructure already embedded into daily life. SpaceX is still building toward infrastructure the market believes could become unavoidable later.

At current valuations, Alphabet offers certainty with optionality. SpaceX offers optionality with extraordinary execution risk.

As companies like SpaceX push investors toward increasingly speculative infrastructure bets, balancing them against proven cash-generating platforms becomes critical. A disciplined portfolio approach helps you stay invested by limiting the impact of market shocks. While consistently beating the market is a challenge, the Trefis High Quality (HQ) Portfolio is designed to make it an achievable goal. The HQ strategy has consistently outperformed its market benchmark since inception, delivering returns of over 105 percent.
