SpaceX (SPCX) shares, which debuted at $135 in the June 2026 IPO and traded near $149 as of late September with an implied market capitalization around $2 trillion, face near-term volatility driven by the first orbital Starship flight test targeted for September 28. Success in deploying initial Starlink V3 satellites on this mission could reinforce revenue momentum from the satellite constellation and AI compute contracts with partners such as Anthropic and Google, supporting trader expectations for continued growth in a business that posted $18.7 billion in 2025 revenue. Conversely, any technical setback or delay would highlight execution risks at the company’s elevated valuation multiples. Broader equity market moves, Treasury yields, and Elon Musk-related developments remain secondary factors that could influence closing levels for the week.
