To the Moon, or to the Margin Call?
Space is hard, but holding onto stock gains might be even harder. After momentarily making Elon Musk the world’s first trillionaire, SpaceX (SPCX) is crashing back down to Earth.
Shares recently breached their $135 IPO price, erasing hundreds of billions in market value. Uncle Sam is watching closely, but Wall Street bears aren’t waiting around for regulatory permission.
Institutional shorts are smelling blood in the low-gravity air. According to report details on CNBC, traders have built an unprecedented $25 billion bet against the aerospace giant.
This massive bearish position represents nearly 29% of the public float. It officially eclipses the absolute dollar volume of the historic Tesla short wars of 2018.
- A staggering $25 billion short position: Bears are aggressively betting on a prolonged descent back to reality.
- Stretched valuation multiples: SpaceX trades at nearly 49 times expected revenue, leaving zero room for execution error.
- The xAI cash burn: Building orbital AI data centers requires billions of dollars in upfront capital.

The Lockup Labyrinth & Orbital Dreams
The immediate threat to the stock isn’t just the short interest, but a looming wall of insider supply. Unlike typical listings with a single cliff expiration, SpaceX has a rolling, staggered lockup structure starting this August.
Every bump in the stock price could trigger early releases, allowing early-stage venture investors to dump their shares. If the market cannot absorb this massive dilution, the floor could fall out entirely.
Musk’s ultimate defense relies on deploying massive ‘orbital data centers’ via Starship Flight 13. These next-generation Starlink V3 satellites promise a 10-fold increase in global bandwidth capacity.
Meanwhile, SpaceX continues to play with its food in the commercial launch sector. While Amazon’s Project Kuiper struggles with launch bottlenecks, SpaceX still controls over 80% of the domestic market.
Betting against Musk has historically been a quick way for short sellers to lose their shirts. The next 180 days will determine if this is a realistic valuation check or the mother of all bear traps.
