SpaceX and OpenAI are moving toward public listings in 2026, drawing intense interest from retail investors who have had limited access to shares in mature technology companies that stayed private for years. Marketplace reported that SpaceX filed its S-1 prospectus ahead of an expected debut next month, with pricing still to come but analysts anticipating what could be the largest initial public offering in history. The filing disclosed a net loss of $4.9 billion last year and showed Elon Musk holds 85 percent of voting power. OpenAI is reportedly preparing for an IPO filing with a fall listing after SpaceX, while Anthropic is also expected to follow. Economist Jay Ritter told Marketplace that companies have delayed going public in recent decades, meaning gains accrued to fewer private investors while business details stayed less transparent. Finance professor Minmo Gahng noted that public companies can no longer cherry-pick disclosures. These firms generate billions in revenue but may not be near-term profitable because of heavy hardware spending.
