Nvidia stock was gaining after key partner Taiwan Semiconductor Manufacturing gave an upbeat outlook on artificial-intelligence processor demand.

One analyst boosted his price target on Nvidia’s stock to a level that would imply a $5.7 trillion market cap, with the chip maker seemingly cleared to sell its H20 chip in China again.

Nvidia took a $4.5 billion write-off in its latest quarter on unsold H20 chips that it was unable to repurpose for other markets. If sales of these high-volume chips to China resume, a reversal of this write-off could boost earnings.
