SpaceX (SPCX) soared 19% on its IPO debut, closing at a $2.1 trillion market cap.
Reddit's r/investing and r/stocks questioned the extreme valuation, while r/wallstreetbets focused on limited supply and potential squeezes.
Cathie Wood's ARK Invest bought 3.3 million shares on day one, and a 2x leveraged ETF (SPCL) launched to capitalize on the momentum.

SpaceX (

$SPCX) closed its first day of trading at $161 per share, up 19% from its IPO price of $135, giving the Elon Musk-led company a market capitalization of roughly $2.1 trillion. The massive debut immediately made

$SPCX the most-discussed ticker across Reddit's finance communities, with 36 posts, nearly 8,000 upvotes, and mixed sentiment between bullish traders and valuation skeptics.

Reddit Split: Valuation Fears vs. Supply Constraints

On r/investing, a highly upvoted post argued that the math on SpaceX doesn't add up: a $2.1 trillion market cap against $18.7 billion in revenue (112x price-to-sales) and a net loss of $4.9 billion. The poster noted that even Nvidia at peak AI mania traded around 30x sales, calling

$SPCX a "story stock" propped up by Starlink profits and a recently merged xAI cash furnace. This sentiment resonated with the cautious crowd, giving

$SPCX a neutral-to-bearish tilt in that subreddit.

Meanwhile, r/wallstreetbets took the opposite view. Multiple posts highlighted that only 4.3% of the company's shares were sold in the IPO, creating an extremely tight float. Institutional insiders are locked up for weeks or months, and many retail brokers are penalizing early selling. One popular post argued this setup could lead to a gamma squeeze when options launch next week, while another pointed to forced buying from index funds as a catalyst. Cathie Wood's ARK Invest buying 3.3 million shares on day one added fuel to the bullish narrative.

On r/stocks, a thread questioned who is actually allowed to sell

$SPCX right now, citing exchange-level bans on flipping. The poster described the situation as "nefarious," suggesting that a practical block on selling power could keep the stock artificially elevated until lockups expire.

News Context: Leveraged ETFs and Analyst Cautions

Within hours of the IPO, Defiance ETFs launched the Defiance Daily 2X Space ETF (SPCL), offering 2x daily leveraged exposure to

$SPCX. The fund is designed for active traders but carries significant risks, including daily rebalancing and concentration risk. Meanwhile, The Motley Fool cautioned that at 100x+ revenue and with net losses from the xAI acquisition,

$SPCX is a high-risk long-term bet on Elon Musk's vision rather than a safe investment. Jim Cramer suggested the mega-debut could unleash a wave of AI-related equity offerings from major tech companies.

Sequoia Capital partner Shaun Maguire called Musk "the most visionary entrepreneur of all time" and predicted 200% year-over-year revenue growth by Q4 2026, driven by data centers, Starlink direct-to-cell, and Starship. Still, the fundamental debate on

$SPCX remains sharply divided between those betting on the story and those balking at the numbers.
