SpaceX IPO'd, and Anthropic and OpenAI Could Go Public in 2026. Should You Buy All Three?

SpaceX completed its IPO on June 12, 2026, raising $85.7 billion at a $1.8 trillion valuation. Shares have surged 23% since the debut, marking one of the largest public offerings in history. The space transportation and satellite company's market entry precedes anticipated IPOs from AI leaders Anthropic and OpenAI, both expected to go public in late 2026 or early 2027.

Anthropic carries a pre-IPO valuation of $965 billion, while OpenAI is valued at $852 billion. Combined, the three companies represent over $3.6 trillion in market capitalization entering or preparing to enter public markets within an 18-month window.

Analysts are flagging valuation concerns across all three names. The Motley Fool warns investors to avoid FOMO-driven purchases, noting that shares could pull back once initial demand dissipates and market focus shifts to fundamentals rather than hype. SpaceX's 23% pop demonstrates the near-term momentum these high-profile listings can generate, but the steep entry valuations leave limited margin for error if growth trajectories disappoint.
