What S&P Sector Will SpaceX Land In After Its IPO?

CNBC reported Sunday that the impending SpaceX IPO is raising an unusually complex question for index watchers: which S&P sector will the company actually belong to?

A Stratospheric Valuation Meets a Classification Puzzle

SpaceX, led by Elon Musk, is targeting a valuation of $1.75 trillion on the Nasdaq. Analysts expect the company to be fast-tracked into major indexes including the S&P 500 and Nasdaq 100. But before that happens, data firms S&P Global and MSCI must decide where SpaceX fits within the Global Industry Classification Standard. The company’s sprawling operations make that decision far from straightforward.

The GICS system funnels every listed company through 163 sub-industries, then up through 74 industries and 25 industry groups, before landing in one of 11 top-level sectors. Those sectors include information technology, communication services, industrials, energy, and seven others. Revenue is the primary input, though earnings and broader market perception also factor into the final call.

Why SpaceX Defies Simple Buckets

SpaceX’s own S-1 filing notes that its Space and Connectivity segments generated the substantial majority of revenue in 2025 and early 2026. Starlink, its satellite internet service, pulled in more than $11 billion in 2025 revenue alone. Rocket launch and mission services added roughly $4 billion. Its xAI division, which houses the Grok artificial intelligence platform and data centers in Tennessee and Mississippi, contributed another $3.2 billion.

That revenue mix points most strongly toward the Communication Services sector, which already includes Alphabet, Meta, Netflix, AT&T, Verizon, and Walt Disney. Notably, EchoStar, a current Communication Services member, holds a small equity stake in SpaceX itself.

A History of Sector Reassignments

Classification is never permanent. S&P Global and MSCI conduct annual reviews and have reshuffled major companies before. Google and Facebook both migrated into Communication Services in 2018 after years sitting inside Information Technology. SpaceX’s industrial operations, including Falcon 9 launches for government clients, could eventually make the Industrials sector a secondary candidate. That bucket already holds Boeing, GE Aerospace, Northrop Grumman, and General Dynamics.

For now, Starlink’s dominant revenue share makes Communication Services the leading bet among analysts. Any investor looking to position ahead of the IPO through sector ETFs will likely want exposure there first.
