Morgan Stanley's shares declined after reports surfaced that OpenAI might postpone its highly anticipated IPO, a deal in which the bank was expected to have a major role. This news compounded existing concerns surrounding the bank's asset management division, as its $7 billion North Haven Private Income Fund imposed withdrawal limits for the second straight quarter due to high redemption requests, signaling potential liquidity stress.

The combination of these developments created negative sentiment around the firm. The potential delay in a major IPO could impact future investment banking revenues, while the issues in its private credit fund raise questions about a growing and important business line. The stock reacted negatively to the IPO news, falling as much as 4.1% during intraday trading on June 26th.
