IPO Frenzy: Is the AI Boom Heading for a Fall?

Investor excitement surrounds recent major IPOs, including SpaceX, with further public debuts anticipated for AI leaders like OpenAI and Anthropic. This surge in new share offerings has prompted debate on Wall Street regarding the market's sustainability.

Historically, periods of high equity issuance in the U.S., such as 1999, 2007, and 2021, have preceded market peaks and subsequent bear markets, according to Capital Economics. Even before recent large offerings, net equity issuance by U.S. non-financial companies had already turned positive by Q1 2026, suggesting the current issuance levels could mirror those of previous boom-and-bust cycles.

However, a contrasting analysis from Deutsche Bank suggests that equity issuance waves often coincide with strong stock market performance. Their research indicates that companies tend to issue equity when demand is robust, earnings are healthy, and investor risk appetite is high. This implies that strong markets often lead to increased issuance, rather than the other way around.

Deutsche Bank's data shows that issuance waves over the past three decades have typically yielded significant median equity returns. They highlight that the current environment is characterized by exceptionally strong equity demand, driven by booming inflows, solid earnings growth, and elevated buyback activity. Household balance sheets also appear capable of absorbing new supply, suggesting strong demand will define this period.
