Uneasy lies the head that wears the crown.

Shares of artificial intelligence czar Nvidia fell 2.6% on Tuesday as signs of unrest continued rippling through its kingdom.

Over the month, Nvidia has been contending with concerns over lofty valuations and an argument from the “The Big Short” investor Michael Burry that companies may be overestimating the lifespan of Nvidia’s chips. That accounting choice inflates profits, he alleged.

The pressure intensified last week in the form of a potential challenger to the crown. Google on Nov. 18 announced the release of its new AI model Gemini 3 — so far so good, given that Nvidia isn’t in the business of designing large language models  — powered by its in-house AI chips — uh–oh.

And on Monday stateside, Meta, a potential kingmaker, appeared to signal that it is considering not just leasing Google’s custom AI chips, but also using them for its own data centers. It seemed like Nvidia felt the need to address some of those rumblings.

The chipmaker said on the social media platform X that its technology is more powerful and versatile than other types of AI chips, including the so-called ASIC chips, such as Google’s TPUs. Separately, Nvidia issued a private memo to Wall Street that disputed Burry’s allegations.

Power, whether in politics or semiconductors, requires a delicate balance.

Remaining silent may shroud those in power in a cloak of untouchability, projecting confidence in their authority — but also aloofness. Deigning to address unrest can soothe uncertainty, but also, paradoxically, signal insecurity.

For now, the crown is Nvidia’s to wear — and the weight of it is, too.
