Tenstorrent raises $1.5bn at $6.2bn valuation

What happened: AI chip start-up Tenstorrent announced a $1.5 billion Series E at a $6.2 billion post-money valuation, according to Tech Startups.

The numbers: The valuation more than doubles that of its December 2024 financing, per the report. Across its two latest major rounds, Tenstorrent has raised more than $2.19 billion.

Who's behind it: Trace Capital and Innovation X led the round. Other participants include ARK Invest, Fidelity Management & Research, Morgan Stanley, T. Rowe Price, SanDisk, Cadence Ventures, Tether Investments, Eclipse, Protagonist, Maverick Silicon and XTX Markets.

In their words: Tech Startups reports the purpose plainly: "The fresh capital will support volume manufacturing of Galaxy systems and broader commercial expansion."

The context: Galaxy is Tenstorrent's server system line. The company also licenses AI and CPU chip IP to companies building custom silicon.

The catch: The figures rest on one outlet. A separate secondary report cites an SEC filing for a roughly $1.29 billion Series E closed in August 2026 and says no official valuation had been announced. That report's numbers differ from Tech Startups', and the discrepancy is unresolved.

Why it matters: A round of this size, with this mix of investors, puts Tenstorrent's Galaxy systems and chip IP licensing on a much larger financial footing than its previous raise.

What's next: Tenstorrent's own release is the figure to watch. Until it confirms the amount and valuation, treat the $1.5 billion and $6.2 billion numbers as reported, not confirmed.
