SpaceX Stock Slides Below IPO Price Amid Starship Launch Abort and Valuation Concerns

Core Event: Starship Launch Abort Triggers Share Decline
On July 16 2026, SpaceX’s Starship V3 test flight was aborted seconds after engine ignition at its Starbase facility in South Texas. A hold activated when “some of the engines didn’t start, triggering an automatic launch abort,” and the company announced it would replace two Raptor engines and attempt another launch “early next week.” The abort sent SpaceX shares down more than 3 percent in after-hours trading, closing at $131.11—its first close below the $135 IPO price.
Background & Context: Record IPO and Early Market Performance
SpaceX went public on June 12 2026, pricing its shares at $135 and raising roughly $85 billion, the largest U.S. IPO ever. The stock opened at $150, surged to a high of $225.64 by June 16, and briefly placed the company among the world’s most valuable firms. Within five weeks, the price fell back to the IPO level, erasing about $1 trillion in market value and leaving early investors underwater.
Data & Statistics: Valuation, Losses, and Lockup Structure
- Market capitalization: estimates range from $1.7 trillion to $2.1 trillion.
- 2025 revenue: $18.7 billion (up 33 % YoY); net loss: $4.9 billion.
- Forward price-to-sales multiple: roughly 40-99 times revenue, far above the Nasdaq-100 average.
- Float: less than 5 % of total shares; 911.5 million shares (? 20 % of total) become tradable after the first earnings release in early August, with additional tranches slated through December 2026.
Why It Matters: Investor Sentiment, Funding Outlook, and Musk’s Net Worth
The share slide reduced Elon Musk’s personal stake value by more than $45 billion, dropping his net worth below $800 billion. Continued sell pressure from upcoming lockup expirations could further depress the price, while a successful Starship flight is viewed as a catalyst to restore confidence in the company’s aerospace and AI ambitions.
Official Statements & Responses
Musk posted on X: “Some of the engines didn’t start, triggering an automatic launch abort,” and later added, “To be confident of a good flight, 2 Raptors will be removed & replaced. Most probable launch timing is early next week.” The Federal Aviation Administration noted the hold was caused by “heat effects on propulsion system components” and “erroneous engine alarm system settings,” and it approved the return-to-flight after corrective measures. UBS analyst Gavin Parsons called the dip “an opportunity” if the upcoming launch validates new milestones.
Criticism & Opposition
Analysts highlight the “extreme valuation” of a company that posted a $4.9 billion loss and projects free-cash-flow positivity only by 2035. University of Arizona finance professor David Brown warned, “Will it make money, and will it make enough money to make all of this worthwhile?” Dec Mullarkey of SLC Management warned that “much of SpaceX is about its xAI ambitions,” suggesting the market may be over-pricing speculative AI projects.
Conflicting Reports & Gaps
Sources differ on the exact market cap (ranging from $1.7 trillion to $2.1 trillion) and on the low-day price (some cite $125, others $131.11). The timing of the first earnings report is described as “early August” and “the first week of August” without a precise date.

What’s Next
SpaceX plans a renewed Starship launch attempt “early next week.” The company’s first quarterly earnings report is expected in the first week of August, which will trigger the initial 911.5 million-share lockup release. Subsequent lockup expirations through December 2026 could increase the tradable float to roughly 40 % of total shares, potentially amplifying price volatility.
