SpaceX's IPO is oversubscribed by up to 4x, with over $250 billion in orders for a $75 billion raise.
Reddit sentiment is mixed: bullish on demand and scarcity, bearish on valuation and lockup risks.
Retail investors are selling other stocks, including AI and semiconductor names, to raise cash for SPCX.
As SpaceX prepares for its landmark IPO on Friday, 
Demand Is Off the Charts — But So Are the Worries
The most discussed post on r/stocks captures the tension perfectly: “Are you ready for the bloodbath tomorrow?” The author, citing a $300 billion drop in pre-IPO futures valuation from $2.3 trillion to $2 trillion, warns of a classic “buy the rumor, sell the news” event. Yet a Reuters-sourced post on the same subreddit notes that demand is approaching four times oversubscribed, with over $250 billion in orders. Elon Musk himself joined investor Zoom calls, adding a layer of celebrity-driven hype.
On r/smallstreetbets, skepticism takes a conspiratorial turn. One post alleges market manipulation by political and institutional players, claiming retail allocation has been cut from 30% to 20% to stoke FOMO. Another user questions the fear of a post-IPO dump, arguing that insider lockups and ETF inclusion will support the price. “How are insiders going to rugpull when they aren’t able to?” they ask.
Valuation Debate Heats Up
A Morningstar report calling SpaceX’s fair value at $63 per share — a 53% discount to the IPO price — has become a lightning rod. On r/wallstreetbets, one user posted “SpaceX at $135...Insanity,” warning that retail investors could be wiped out. The post gained 50 upvotes and 104 comments, reflecting deep unease beneath the surface optimism.
News outlets echo the valuation concerns. The Motley Fool highlighted that SpaceX’s valuation multiples exceed those of Nvidia and Apple, while Benzinga noted that Starlink’s $4.4 billion operating income is strong but the $26.5 trillion AI total addressable market is largely speculative. Morningstar’s fair value estimate of $63 per share is a recurring reference point across both Reddit and financial media.
Retail Rotation: Selling AI to Buy Space
A Benzinga report on Thursday revealed that retail investors have been net sellers of equities for three consecutive days, with the heaviest selling in semiconductor and AI stocks like Micron and AMD. BNP Paribas estimates retail and passive flows into SpaceX could reach $50 billion, potentially amplifying selling pressure through unwinding leveraged ETF positions. This rotation underscores the gravitational pull of the SpaceX IPO on the broader retail trading ecosystem.
The Lockup Schedule: A New Source of Complexity
A detailed post on r/wallstreetbets broke down SpaceX’s unconventional lockup schedule, which is tied to both calendar days and earnings reports rather than a standard 180-day cliff. The post, which gained 70 upvotes and 79 comments, outlined that friends and family can sell immediately, retail participants can sell after 15 days, and insiders face staggered unlocks. This complexity has added another layer of uncertainty for traders trying to time their exits.
The broader space sector also rallied Thursday ahead of the debut. Momentum Inc. gained 28%, Virgin Galactic jumped 22.6%, and other space names like Intuitive Machines and Rocket Lab rose as investors rotated into space-themed stocks lacking direct SpaceX exposure, per Benzinga.
