As the possibility of a SpaceX initial public offering becomes clearer, U.S. space-industry stocks are again drawing Wall Street attention. Markets see a SpaceX listing as more than a mega IPO and an event that could change valuation standards across the space sector.

BeInCrypto, a blockchain outlet, reported on May 8 that SpaceX may disclose its S-1 filing as early as late May and could start the listing process in late June or early July. Markets are focusing on the cost structure of its launch business and Starlink profitability indicators that would be disclosed during the listing process.

SpaceX, which is still privately held, has disclosed little externally about its space launch costs and the actual profit structure of its satellite communications business. If it pursues an IPO, related financial information would appear in the market for the first time, an analysis said. That could lead to a re-rating of valuations across the space sector.

Rocket Lab is cited as the most direct beneficiary and comparison target. Rocket Lab is a leading listed space company that produces launch vehicles, satellites and space components in-house, and markets view it as the public company with the most similar business structure to SpaceX.

Rocket Lab’s recent results are extending a growth trend. First-quarter revenue this year rose 63.5 percent from a year earlier to $203 million, and its backlog stood at $2.2 billion. Liquidity also exceeded $2 billion, and it is seen as maintaining a stable financial structure. Its shares, however, have seen profit-taking after surging about 240 percent over the past year, and ended at $78.58 on May 7. It fell 7.17 percent on the day.

AST SpaceMobile is also cited as a key stock linked to a SpaceX IPO. AST SpaceMobile is building a low-Earth-orbit satellite communications network that connects directly to ordinary smartphones and has secured AT&T and Verizon as key partners.

Markets say that if SpaceX discloses Starlink subscriber numbers and average revenue per user during an IPO process, it would provide a first benchmark for valuing AST SpaceMobile by comparison.

Near-term negatives also exist. AST SpaceMobile’s BlueBird 7 satellite failed to enter orbit in April, creating pressure on its goal of securing 45 satellites by year-end. The company plans to pursue BlueBird 8 to 10 launches via Falcon 9 in mid-June. Its shares ended at $65.35 on May 7, about half the record high set in February.

A company drawing attention on profitability is Intuitive Machines. It is developing lunar landers and participating in a U.S. National Aeronautics and Space Administration near-space network business, and is also involved in the Artemis programme alongside SpaceX.

Markets describe Intuitive Machines as the only pure-play listed space company to present positive adjusted EBITDA for 2026. The company set 2026 revenue guidance at $900 million to $1 billion, about 5 times larger than the previous year. It also formalised plans to turn profitable.

The industry sees a SpaceX IPO as something that could fundamentally change investment flows in the space sector. Space companies have been valued based on future growth and technology. If SpaceX discloses actual launch costs and Starlink margin structure, markets are likely to reassess related companies on more specific profitability and cost benchmarks.

As a result, Rocket Lab is drawing attention as a launch and supply-chain comparable, AST SpaceMobile as a satellite communications comparable, and Intuitive Machines as a profitability comparable. Which numbers appear in SpaceX’s forthcoming S-1 filing is emerging as a key variable that could determine the direction of space-related stocks broadly.
