Wall Street is flooding the artificial intelligence sector with unprecedented capital through multiple financing channels. Alphabet's recent $85 billion equity raise exemplifies the rush to fund data-center investments, while tech companies pursue IPOs and bond sales at record pace across global markets.

The so-called AI hyperscalers—Alphabet, Amazon, Meta, Microsoft and Oracle—have issued $159 billion of bonds globally this year, more than double the previous year's volume. Meanwhile, SpaceX, Anthropic and OpenAI prepare for public listings that could make 2023 the biggest year ever for tech IPOs.

Investors remain divided on whether the AI build-out will create lasting value or lead to overspending. Still, demand has defied skeptics: tech stocks in the S&P 500 remain up 31% this quarter, with Anthropic's surprise quarterly profit adding fuel to the AI investment frenzy.
