Morgan Stanley will soon open a key wealth management funnel to artificial intelligence agents from thousands of corporations, CNBC has learned exclusively. It's one of the earliest instances of a major Wall Street bank opening its platforms to external AI tools.

The move will allow clients' autonomous agents to pull data and insights directly from the firm's stock administration platforms, ShareWorks and Equity Edge, bypassing the traditional software interfaces built for human users, according to Mark Mitchell, chief product officer of Morgan Stanley at Work.

In April, Morgan Stanley executives attributed $1.2 trillion in assets gathered to its workplace strategy.

"The way we see it, in a future state, our corporate clients will not be logging into ShareWorks or Equity Edge," Mitchell said.

Instead, they'll be "using agentic AI-powered tools on their desktops within the four walls of their companies, interacting with our platforms in a purely agentic way," he said.

The bank has already granted a handful of clients early agentic access and plans to open it up to the firm's 3,400 administration clients by next year, Mitchell said.

It's the latest sign that Wall Street is preparing for a future where AI agents handle tasks now performed by software users.

Rivals including JPMorgan Chase and Goldman Sachs are using AI agents internally for things like writing code, but have yet to publicly announce steps to allow external agents to connect directly to their firms' systems.
