Big tech is turning to equity markets to fund AI ambitions, raising questions about investor capacity.
Alphabet plans to raise $85 billion through stock sales next quarter, the largest equity issuance on record. Meta is reportedly considering a similar multi-billion dollar offering. Pending IPOs from SpaceX, Anthropic, and OpenAI could add nearly $4 trillion in market capitalization.
AI-related debt issuance reached $121 billion in 2025, four times the prior five-year average, with projections of an additional $1.5 trillion. Market volatility is rising as investors question return on investment and sustainability.
Not everyone is bearish. DataTrek's Nicholas Colas argues global investable wealth is sufficient to absorb new offerings. Evidence includes oversubscribed demand for SpaceX's IPO filing.
The shift from self-funding to external financing alters the risk profile of big tech investments. An $85 billion equity offering dilutes existing shareholders directly, and up to $4 trillion in new market cap will require capital from new money or reallocation of existing holdings.
