Nvidia (NASDAQ:NVDA) rival AI chip startup Etched is reportedly in talks to raise funds at roughly a $20 billion valuation, quadrupling its prior mark.

Existing backer Jane Street is spearheading the new financing, The Wall Street Journal reported on Friday, citing sources.

Separately, Etched is raising a round led by Sequoia Capital at a $10 billion valuation.

Neither deal has closed, and terms may still shift.

Etched did not immediately respond to Benzinga‘s request for comment.
