Jim Cramer Warns ETF-Only Investors Risk Missing AI Bull Market Winners

CNBC’s Jim Cramer cautioned on May 28, 2026 that many investors are sidelined from the AI rally due to three critical errors, most prominently an overreliance on index-tracking exchange-traded funds. Speaking on “Mad Money” after Snowflake (SNOW) shares surged about 36% on strong earnings and a $6 billion AWS commitment, Cramer said investors who limit themselves to ETFs never directly own individual winners. He also faulted investors for dismissing “obvious” AI opportunities, naming Salesforce (CRM), Oracle (ORCL) and Microsoft (MSFT) as likely beneficiaries. The third mistake, he said, is a lingering fear of a 2000-style crash that ignores the real profits and cash flows behind today’s AI leaders. Cramer instead touted the AI infrastructure supply chain, highlighting Micron (MU), Seagate (STX) and Western Digital (WDC) amid surging demand for high-bandwidth memory and storage. Dell Technologies (DELL) this week reported AI server revenue up 757%, lifting its full-year AI outlook to $60 billion. Cramer argued the AI data-center buildout remains far from over.
