SPCX vs S&P 500: History Says ETF Wins?

Jul 3, 2026
Bobby Quant Team

💡 Key Takeaway

History shows most large IPOs, including SpaceX, underperform the S&P 500, making an S&P 500 ETF a safer long-term investment.

SpaceX's Rocky Public Debut

SpaceX (SPCX) went public last month in the largest IPO by market cap in history. Despite the hype, the stock has fallen nearly 21% from its June 16 peak.

Historical data from FactSet Research reveals that eight of the top ten largest U.S. IPOs have underperformed the S&P 500 since going public. Collectively, these stocks lagged the index by a median of 127 percentage points.

Early trading performance is not a reliable indicator of long-term success. Meta Platforms rose only 1% on its first day but has outperformed the index, while Coinbase Global surged 31% initially yet underperformed by 136 percentage points.

CEO Elon Musk's ambitious goals—including space-based data centers and a Mars colony—add to the uncertainty. The company is not yet profitable and appears overvalued by key financial metrics.

Why This Comparison Matters for Investors

The article directly challenges the narrative that high-profile IPOs like SpaceX are guaranteed winners. For investors, this means the stock could face prolonged volatility and underperformance compared to a diversified index.

SpaceX's lack of profitability and lofty valuation make it a high-risk bet. Meanwhile, the S&P 500 ETF offers decades of consistent returns with lower volatility.

If history repeats, SPCX could continue to trail the broader market. This is crucial for investors deciding between a single-stock gamble and a diversified approach.

The analysis also highlights that even strong first-day pops (like Coinbase) do not ensure long-term gains, reinforcing the idea that patience and diversification often win.

Bobby Insight

Investors should favor S&P 500 ETFs over SpaceX given historical underperformance of large IPOs and SpaceX's current unprofitability and overvaluation.

The data clearly shows that most mega-IPOs fail to beat the market. SpaceX's high valuation and lack of earnings make it especially risky. An S&P 500 ETF offers proven long-term returns with less uncertainty.

What This Means for Me

means-for-me

SPCX
Negative
SpaceX stock is down 21% from its peak, unprofitable, overvalued, and faces historical headwinds as a large IPO. CEO's speculative goals add uncertainty.
META
Neutral
Meta is a rare large IPO that outperformed the S&P 500, but its first-day performance was modest. Its success does not guarantee similar outcomes for other IPOs.
COIN
Negative
Coinbase surged on its first day but has since underperformed the S&P 500 by 136 percentage points, illustrating the risk of buying into hype-driven IPOs.

SpaceX IPO: AI Rotation or Market Crash?

Neutral Megacap IPOs like SpaceX will rotate capital out of AI infrastructure stocks like Nvidia, but a 40% crash is unlikely given market size.
