US equity financing tops $300B as AI giants tap capital markets

US companies have raised more than $300 billion through stock sales this year, nearly 50 percent above Wall Street's initial forecast, as Alphabet and SpaceX lead an AI-driven fundraising wave reshaping capital markets.

US companies have raised more than $300 billion through stock sales in 2026, surpassing Wall Street's initial $200 billion to $225 billion forecast, as Alphabet and SpaceX lead an AI-driven fundraising wave reshaping capital markets.

"The sheer volume reflects how AI infrastructure demands are outstripping internal cash flows even at the largest technology companies," a capital markets strategist told The Information. "Equity issuance is becoming a structural feature, not a cyclical one."

SpaceX's $75 billion initial public offering at a $1.75 trillion valuation — priced at $135 per share — represents the largest single equity raise of the year. The company's 2025 capital expenditure of $207 billion, with about 60 percent directed toward artificial intelligence, will fund AI computing capacity and satellite network expansion. Alphabet has opened an $80 billion to $90 billion equity refinancing program through common stock sales, mandatory convertible preferred shares and an at-the-market issuance plan, responding to annual AI capital spending of $180 billion to $190 billion.

The $300 billion year-to-date total already exceeds the full-year equity issuance of any year since 2021, according to data compiled by The Information. Additional supply is building: OpenAI and Anthropic, both preparing public listings, could add $70 billion in AI-related issuance. OpenAI has signaled it may delay its IPO until 2027, with Chief Executive Officer Sam Altman targeting a $1 trillion valuation. Anthropic has filed confidentially for an IPO, with a potential listing as early as October. The backlog of large technology issuances means the full-year total will almost certainly rise further.

Two Forces, One Market

The flood of equity supply creates a dual dynamic for investors. On one side, the absorption of more than $300 billion in new stock drains liquidity from secondary markets, particularly for sectors outside artificial intelligence. Non-AI equities face sustained pressure as institutional capital rotates toward new issuances and the companies that underwrite them. On the other side, the capital raised converts directly into AI infrastructure spending — data center construction, graphics processing unit procurement and network buildout — providing order pipelines for hardware suppliers such as Nvidia, semiconductor companies and energy providers.

The last time US equity issuance approached this scale was during the SPAC boom of 2021, when special-purpose acquisition companies raised more than $160 billion. That cycle ended with many SPACs trading below their trust values. The current wave differs in that the capital is flowing to established operating companies with identifiable revenue from AI products, rather than blank-check vehicles with speculative merger targets.

What Comes Next

The queue of pending issuances remains crowded. Beyond OpenAI and Anthropic, Alphabet may return to equity markets for additional tranches if its AI capital spending trajectory continues. The combined capital expenditure plans of the largest cloud service providers exceed $750 billion, creating a persistent funding gap that debt markets alone cannot fill.

For investors, the structural divergence between AI and non-AI equities is likely to persist as long as the issuance cycle continues. Companies with direct exposure to AI infrastructure spending benefit from the order flow, while those outside the AI supply chain face a prolonged liquidity headwind. The next milestone to watch is the third-quarter earnings season, when companies will disclose updated capital expenditure plans for 2027, potentially triggering another wave of equity financing announcements.
