Billionaire investor Bill Ackman said the U.S. stock market has turned into a "casino," warning that speculative trading has overtaken fundamental investing. The remark from the Pershing Square founder adds to a growing chorus of Wall Street figures flagging elevated retail speculation and stretched equity valuations. Ackman did not attach specific numbers or targets to the comment, leaving investors to read it as a broad caution on market conditions rather than a call on any single stock or sector. The comment matters because Ackman's public statements have historically moved sentiment, and his "casino" framing echoes earlier warnings from peers about momentum-driven trading. What to watch next is whether other high-profile investors amplify the caution and whether volatility picks up in speculative corners of the market.
