Tenstorrent raises US$1.5 billion; revenue isn't disclosed

Tenstorrent, the AI chip company Jim Keller runs as CEO, raises US$1.5 billion at a US$6.2 billion post-money valuation

Concept illustration: a pale banner at the top is lettered TENSTORRENT beside a cube icon with orange, yellow and blue faces, and below it a flat cart heaped high with round brick-red discs stands near an open doorway on the left, its right end beside the base of a tall black rack lettered GALAXY that is filled top to bottom with stacked units. On the right a person in black clothes and white shoes, with a white card on a lanyard, stands looking toward the rack, against a pale wall with a large faint pink circle behind the scene.

Why it matters: Tenstorrent now has money for volume production. The only Galaxy shipment and customer figures so far are self-reported by CEO Jim Keller, from a June interview. We make no call on this item yet.

Tenstorrent closes a US$1.5 billion Series E at a US$6.2 billion post-money valuation, to fund volume production of its Galaxy servers and design-IP licensing, with Samsung and LG named as licensees (Tenstorrent newsroom, 2026-10-19). In June, CEO Jim Keller said Tenstorrent was building 1,000 Galaxy servers, more than half already sold, a self-reported figure (EE Times via Tenstorrent newsroom, 2026-06-25).

Not proven yet: the press release gives no revenue, customer count or shipment figures How we checked →

Judgment update: No call on this item yet. If Galaxy shipment and customer counts are published, they will be checked against the 1,000 units Keller cited in June.
