Shares of SpaceX slid 5.1% to $110.14 on July 27, extending a punishing week that has erased nearly $13 per share since Monday's close of $123.54, as investors sold the news of Starship's first operational satellite deployment despite the mission's technical success. SpaceX Delivers Its First Satellites on Starship — So Why Is the Stock Still Falling, and Can a $1.5 Trillion Valuation Survive Without a Reusable Booster?

Shares slid 5.1% to $110.14 Monday, extending a brutal week that has vaporized $13 per share since last Monday's close of $123.54. SpaceX successfully deployed the first batch of next-generation Starlink satellites on Friday using its massive Starship rocket — the 13th test flight of the system. Yet investors sold the achievement, dragging SPCX to within striking distance of its 52-week low of $110.85 — a stock that peaked at $225.64 just six weeks after its June 12 IPO .

The Mission Worked, But the Booster Failed — Again

Starship deployed all 20 next-generation Starlink satellites and its heat shield showed significant improvement over prior tests. But the Super Heavy booster failed during a planned landing simulation — the second time the newest version has had a booster problem.

That matters because Starship's entire business case depends on recovering and re-flying hardware. Every booster lost in the ocean is roughly $200 million in hardware SpaceX cannot reuse.

A Premium Stock Price Demands Flawless Execution

With roughly 13.2 billion shares outstanding and a market cap near $1.5 trillion, SpaceX trades at about 40 times estimated 2026 revenue of $39.1 billion — a premium that assumes near-perfect execution.

The company's trailing earnings per share remain negative at -$2.94 , and its AI segment is still unprofitable despite heavy investment.

The first earnings report on August 6 will trigger a lock-up expiry releasing up to 911.5 million insider shares — a flood of potential selling into an already weak tape.

Starlink Growth Is Slowing Where It Counts

Starlink's average revenue per subscriber has dropped from $99 in 2023 to $66 in Q1 2026 as the service expands into lower-income markets. Amazon's rival satellite network is also approaching competitive scale. Without a reusable Starship driving down launch costs, the economics of frequent satellite deployments become less attractive and network expansion could slow.

What Comes Next Is Harder Than What Came Before

SpaceX still must demonstrate full orbital flight and in-space refueling — a requirement for its NASA moon-landing contract.

Industry expert Tim Farrar noted SpaceX "remains a long way from achieving rapid reusability of the entire ship." Until boosters start coming home intact, the gap between Starship's promise and its price tag will keep widening.
