AI chip startup Etched, based in San Jose, sees its valuation rise to $21 billion within less than a month, according to reporting. The increase follows a prior valuation of about $10.3 billion tied to a funding round closed in July.

The outlets describe the latest jump as a valuation doubling after Etched’s earlier financing milestone. Quartz reports the company’s valuation expands beyond the level associated with its July Series C round, which is described as worth $10.3 billion. Channel NewsAsia reiterates that Etched’s valuation doubles to $21 billion in the same short time frame. Both accounts focus on the size and speed of the valuation increase, offering limited additional details on the mechanism driving the repricing and providing no clear view of whether it reflects a new funding round, market reassessment, or other investor actions.
