Wall Street analysts are growing more bullish on Nvidia, with some now mapping out a credible path to a $10 trillion market valuation — a figure that would make it the most valuable company in history by a wide margin.

According to Trefis, there is a scenario in which Nvidia reaches that milestone, driven by sustained and accelerating demand for its AI chips. The analysis raises the question of whether the stock, despite already sitting at historically high valuations, may still be undervalued relative to the AI buildout ahead.

Yahoo Finance echoes that optimism, with analysts predicting the second half of 2026 will be a "game-changing moment" for the company. The argument centers on a wave of AI infrastructure spending expected to intensify as enterprises move from experimentation to full-scale deployment — a shift that would disproportionately benefit Nvidia's data center business.

Adding near-term fuel to the story, Simply Wall St reported on a new data center deal with SharonAI, the latest in a string of agreements that underscore how broadly Nvidia's hardware has become the default choice for companies building AI infrastructure.

The broader backdrop is a global race among tech giants, governments, and startups to secure AI computing capacity. Nvidia holds an outsized share of that market through its dominant GPU lineup and software ecosystem.

If the analysts are right, the second half of 2026 won't just matter for Nvidia shareholders — it could mark the moment AI spending shifts from hype to the kind of sustained, measurable economic force that reshapes entire industries.
