About the company

SpaceX builds and launches reusable rockets and spacecraft for NASA, the military, and companies, and it runs Starlink, a satellite internet service for homes and businesses. In 2020, its Dragon capsule became the first privately built spacecraft to carry astronauts to the International Space Station. Its Falcon 9 rocket lands its first stage so the booster can fly again, which cuts launch costs, while Starlink beams internet from low-orbit satellites to small dishes for a monthly fee. SpaceX also owns xAI, maker of the Grok chatbot and owner of the social network X, and is building Starship, a fully reusable rocket meant to carry people to the Moon and Mars. Elon Musk founded SpaceX in 2002, and it is based in Starbase, Texas.

Simplify's Take

What believers are saying

  • Starlink demand keeps compounding: subscribers doubled to 12 million in the year to June 2026.
  • Room to grow: SpaceX listed 2,693 open roles in October 2026, over a third of them for Starlink.
  • Rivals rent its AI supercomputers: Claude maker Anthropic agreed in May 2026 to pay SpaceX $1.25 billion a month.

What critics are saying

  • Stock grants swing hard: shares closed between $108 and $211 in the four months after the June 2026 IPO.
  • Expect long weeks: 1,724 of SpaceX's 2,693 job posts in October 2026 mention extended hours and weekend work.
  • AI spending outruns sales: SpaceX put $15.8 billion into AI data centers in the June 2026 quarter, double its revenue.

What makes SpaceX unique

  • SpaceX is the world's busiest launcher by far: its 165 orbital launches in 2025 were nearly double China's total.
  • Starlink carries the profits: it earned $1.7 billion in the June 2026 quarter, while rockets and AI lost $1.8 billion.
  • Elon Musk has the final say: super-voting shares give him about 82% of shareholder votes after the June 2026 IPO.

Musk eyes $500B–$1T SpaceX revenue by 2027 as Q3 sales jump 161% to $14.6B

SpaceX chief executive officer Elon Musk expects the company's annual recurring revenue to reach between $500 billion and $1 trillion by the end of 2027. He made the claim on the October 20 earnings call, citing growth in its "super intelligence" (SI) business. SpaceX reported third-quarter revenue of $14.6 billion, up 161% year over year, and its first quarterly net profit of $4.4 billion. SI revenue rose 830%, driven by cloud computing deals, the Cursor acquisition, and Grok's enterprise business. Risks remain. Third-quarter capital spending was $19.6 billion, and free cash flow was negative $10 billion. The stock trades at 63 times trailing-12-month sales.

SpaceX's AI unit overtakes Starlink with $7.56B revenue and 84% of $19.6B capex

SpaceX's AI unit, renamed "Super Intelligence," overtook Starlink in revenue in the third quarter. The unit's revenue rose 830% to $7.56 billion, against $5.25 billion for Starlink. Total revenue was $14.6 billion, up 161%. AI also took most of the spending. Of $19.6 billion in capital expenditure, $16.4 billion went to AI. SpaceX expects fourth-quarter capex of $35 to $40 billion. Starlink still earned $2.37 billion of the company's $2.79 billion operating income. Shares fell 9% on October 22 on capex concerns. Meanwhile, the Space segment lost $7 million on $1.77 billion of revenue.

PhillipCapital double-upgrades SpaceX to buy, triples price target to $250 after first profit

PhillipCapital has upgraded SpaceX stock from "sell" to "buy" and tripled its price target from $75 to $250. The target implies a gain of nearly 73% from Thursday's close of $147.06. SpaceX shares rose 1.5% on Friday. The upgrade follows the company's first quarterly profit as a public company. In the third quarter, it reported adjusted earnings of $0.45 per share on revenue of $14.58 billion, beating expectations. Analyst Glenn Thum credited growth in AI cloud services, which gained from higher rental pricing, and Cursor, which added $608 million from mid-August. Enterprise and government revenue rose 91% year-over-year on aviation connectivity and Starshield contracts. Thum warned that 2027 revenue could miss projections, and that power and cooling limits could slow expansion.

T-Mobile US stock falls 5% as SpaceX reportedly eyes 80,000 towers after $8B spectrum deal

T-Mobile US shares fell 5% by 11:15 on Friday after Bloomberg reported that SpaceX plans to lease 80,000 cellphone towers and build a fourth major US mobile carrier to compete with T-Mobile, Verizon, and AT&T. Two weeks ago, SpaceX said it would pay $8 billion to Grain Management for up to 14 megahertz of paired spectrum in the 800 MHz band. It said the deal would help Starlink Mobile become a major US carrier. The towers would supplement the 15,000 direct-to-cell Starlink satellites SpaceX has asked the Federal Communications Commission to let it launch. SpaceX earns a 45% operating margin from its Starlink connectivity business. T-Mobile's margin is 22%, and new competition could push it lower.

SpaceX shares end rocky week as $5.2B Starlink quarter and Tesla merger talk collide with selloff

SpaceX investors had a rocky week. A third-quarter report that beat estimates and Elon Musk's backing of a Tesla merger lifted shares 9% on Wednesday, but a tech selloff over AI worries erased the gain on Thursday. Connectivity revenue, mostly from Starlink, rose 69% to $5.2 billion. Starlink added 1.6 million subscribers, bringing the total to just under 14 million. Bloomberg reports SpaceX is in talks with Crown Castle and American Tower to lease space on 80,000 US cell sites for a terrestrial mobile network. Shares rose on Friday and are up 1% for the week. SpaceX and Tesla have each formed special committees of independent directors to explore a merger. A combined company would be worth about $3.5 trillion, though Musk flagged the need for approval from 50% of Tesla shareholders.
