Even Nvidia ‘s trillion-dollar growth narrative isn’t enough to jolt its stock out of a six-month rut, one sign that the chipmaker’s biggest challenge may now be its own size. Despite dominating the artificial intelligence boom and touting long-term revenue potential that could exceed $1 trillion, Nvidia’s stock has lagged peers and failed to respond meaningfully to bullish updates. The stock is down about 2% in 2026, a little bit more than the S & P 500 decline. The muted reaction underscores a theory on Wall Street that Nvidia may have crossed a threshold where traditional equity dynamics no longer apply. “The market cap has gotten so large that Nvidia no longer trades like other stocks,” TD Cowen analysts wrote in a note on Monday. “The reality is there are trading and fund-flow dynamics at play with a > $4T company that we, and investors, are not used to. We think this is driving a few factors that are capping the stock for now.” Nvidia’s market capitalization early Tuesday came to some $4.45 trillion, according to FactSet data, more than any other U.S. company, even Apple or Microsoft . NVDA YTD mountain Nvidia year to date Nvidia is no longer trading like a typical semiconductor company, and its size alone is introducing new constraints — from fund flows to portfolio construction — that are capping the stock’s potential upside, even as the business fundamentals remain strong, TD Cowen said. To double from current levels, Nvidia would need to approach a $9 trillion valuation — equivalent to the combined economic output of Germany and India, TD Cowen noted. That kind of upside is increasingly difficult to achieve, particularly for growth-oriented investors seeking asymmetric returns. Among the factors capping Nvidia, “the simplest one we’ve observed is it’s a lot harder to add the next $2T in market cap than the last $2T. Many investors, at least the ones that talk to semis analysts, want to pick stocks that they can at least create scenarios of them doubling,” the investment bank said. As a result, some portfolio managers are looking elsewhere in the AI ecosystem, particularly among suppliers and infrastructure plays tied to Nvidia, where the potential for outsized gains appears greater, TD Cowen said. “To put it bluntly, the generalist community needs more convincing on the durability of Nvidia’s position, and more importantly AI spending, than do semis and tech investors,” the analysts said.
