Jim Cramer warns this overlooked danger could threaten the market rally

CNBC's Jim Cramer warned Monday that a wave of massive initial public offerings and capital raises could threaten the bull market. Anthropic , the company behind Claude, filed its IPO prospectus Monday, moving one of Wall Street's most anticipated public debuts a step closer. Investors have long awaited public offerings from AI leaders Anthropic and OpenAI , but Cramer said that their potentially massive fundraising needs could strain an already crowded market. With $148 billion raised through IPOs so far this year, he fears the influx of new shares could outstrip investor demand and derail the rally.
