SpaceX, OpenAI, Anthropic Mega‑IPOs Test Retail Demand
Prospective mega‑IPOs from SpaceX, OpenAI and Anthropic will hinge on retail investor appetite amid a shaky market: SpaceX (now combined with xAI) confidentially filed to raise roughly $75 billion and reportedly plans to set aside about one‑third of shares for retail. OpenAI’s recent $122 billion funding round included allocations for wealthy private clients, and Anthropic is widely expected to pursue its own offering. The piece argues private markets and retail sentiment are increasingly decisive for large tech listings. The newsletter also notes broader tech finance and corporate moves: Snap attracted activist investor Irenic (a 2.5% stake) pushing governance and cost cuts; Q1 VC fundraising hit records; Saronic raised $1.75 billion; Mercor suffered a damaging breach as Anthropic lost some source code; OpenAI and Anthropic completed smaller strategic acquisitions; Doug Leone took a new chairman role at Sequoia.
Mega‑IPOs and large funding rounds from major AI and space companies could materially shift investor flows, valuation benchmarks and retail participation, with knock‑on effects for capital allocation across tech and media sectors.

Anthropic Advances Toward Mega-IPO with Bank Meetings
Anthropic is scheduling investor meetings ahead of a potential initial public offering later in 2026, signaling advancing IPO preparations. The company confidentially filed an IPO prospectus with the SEC in June and bankers are gauging investor demand; Bloomberg reported a possible public debut as soon as October. Goldman Sachs, Morgan Stanley and JPMorgan Chase are involved in the offering. Anthropic closed a $65 billion funding round in May that valued the company at $965 billion, positioning it ahead of rival OpenAI on valuation. An IPO would build on recent tech market momentum following SpaceX’s June listing.
AI Companies Race to IPO After SpaceX Debut
TechCrunch’s Equity podcast discussed how SpaceX’s record‑setting IPO — highlighted by the company’s AI ambitions and Elon Musk becoming the world’s first trillionaire — appears to be catalyzing a new wave of public market activity. OpenAI and Anthropic have confidentially filed to go public and may seek IPOs soon. Reporters on the episode noted a market ripple effect: startups and SPACs (for example, Quantum Space) are trying to ride SpaceX’s momentum, legacy automakers are re-purposing battery capacity toward data‑center energy needs, and public markets may shift capital from consumer/social companies toward AI labs and deeptech. Hosts warned the rush to public markets could stress test valuation expectations and corporate structures as several AI labs compete for finite investor capital.
Cramer: Mega IPOs Could Threaten Market Rally
CNBC host Jim Cramer warned that a coming wave of large initial public offerings — notably from OpenAI, SpaceX and Anthropic — could drain liquidity and disrupt the market’s rally. He argued that heavy investor demand for those high-profile AI and space companies would likely pull capital away from the S&P 500 and other equities. Cramer said OpenAI’s public listing could depend on a legal dispute involving Elon Musk and Sam Altman, and that SpaceX could command a valuation of $1 trillion or more (he suggested as high as $2.5 trillion given Musk’s track record). He described Anthropic as enterprise-focused and “sticky,” noting strong institutional demand and potential closeness to profitability. Cramer framed the risk as not immediate but significant if the trio of IPOs hit the market around the same time.
