- While IPO volume has dropped 41.5% in 2026, capital raised has surged 35% as larger companies dominate

Elon Musk’s SpaceX has submitted confidential documentation for a public stock offering that could shatter all previous IPO records. The aerospace manufacturer is pursuing a staggering $1.75 trillion market capitalization while seeking to secure $75 billion through the public markets.
Should this valuation materialize, SpaceX would climb ahead of Tesla to become America’s eighth-most-valuable publicly traded corporation.
Musk, who simultaneously leads Tesla, has already demonstrated his ability to generate exceptional returns — Tesla shareholders have enjoyed roughly 23,000% gains since the electric vehicle maker’s 2010 market debut. Many are wondering if SpaceX can replicate that extraordinary performance.
SpaceX generated approximately $16 billion in annual revenue throughout 2025, alongside $8 billion in net profits. These figures place the company on remarkably solid financial ground compared to typical IPO candidates.
The aerospace giant operates Starlink, its satellite-based internet service, and recently completed a merger with Musk’s xAI venture, which encompasses both the Grok artificial intelligence system and the X social platform.
SpaceX isn’t the only tech titan preparing for a public market entrance. Artificial intelligence powerhouses OpenAI and Anthropic are both anticipated to submit IPO filings before 2026 concludes. The trio’s combined market value could surpass $3 trillion.
David Solomon, Goldman Sachs’ chief executive, recently noted during an earnings discussion that equity markets have demonstrated “exceptional strength” and suggested IPO momentum may intensify. Meanwhile, Morgan Stanley’s CEO Ted Pick observed that investor standards for new public offerings remain “exceptionally elevated” under current market conditions.
The Evolving IPO Environment
The 2026 IPO landscape reflects a clear trend toward quality over quantity. By mid-April, just 38 companies valued above $50 million had completed public debuts — representing a 41.5% year-over-year decline. Despite fewer listings, total capital raised has climbed 35% to reach $13.3 billion, per Renaissance Capital’s tracking.
This week witnessed Madison Air, a filtration systems manufacturer, complete 2026’s largest IPO to date, securing $2.2 billion at a $13.3 billion valuation. Shares jumped nearly 20% during opening trading. Defense technology company Arxis pulled in $1.1 billion and saw its stock surge 38% on day one.
However, not every 2026 IPO has celebrated success. Cryptocurrency platform BitGo, oncology-focused biotech Eikon Therapeutics, and diabetes technology developer MiniMed are all currently trading substantially beneath their initial offering prices.
Historical Patterns Suggest Caution
While enthusiasm surrounding SpaceX runs high, historical performance data suggests investors should temper expectations for the immediate post-IPO period.
Since 1999, the largest market debuts have consistently struggled during their first six months as public companies. Facebook plummeted 38% within half a year of trading. Alibaba declined 9%, General Motors slipped 8%, and Saudi Aramco shed 15%. Only Visa bucked the trend, climbing 23%. Collectively, these mega-IPOs averaged approximately 10% losses during their first six months.
If SpaceX follows this historical pattern with a 10% drop, investors would witness roughly $175 billion in market capitalization evaporate.
Retail investors must also consider whether the most significant appreciation has already occurred during private funding stages. While pre-IPO investment vehicles from ARK Invest, Robinhood, and Baron Capital provide some access, these funds have experienced considerable volatility throughout the past year.
SpaceX has yet to disclose when it will publicly file its registration statement or establish a definitive timeline for beginning public trading.
