2026-10-20 — Jim Keller's chip startup more than doubles, and stays independent

Tenstorrent, the Toronto company building AI chips on the open RISC-V instruction set, raised $1.5B and said it is now worth $6.2B — more than double what the map carried, and an answer to the question that has hung over it all year: approached by both Intel and Qualcomm, it took outside money instead of selling. Elsewhere a two-year-old startup called Town became a unicorn by giving every employee their own assistant, and joins the map on the rivalry that nearly cost it the round.

Marks moved

New edges

• town —rivals→ instinct — the two sides of the personal-agent race, and the reason Town's round changed hands: Index Ventures had signed a term sheet to lead it at the same $1B, then withdrew, as did Conviction, after Instinct — also an Index investment — complained of a conflict of interest. Upstarts Media, 2026-09-03, reported.
• modal —builds_on→ nvidia — Modal will host agents on NVIDIA's new Vera CPUs, its first use of them, alongside the Intel and AMD parts it runs today; the map had no edge at all between a serverless GPU platform and the company whose GPUs it serves. Reuters, 2026-10-19, reported.
• perplexity —builds_on→ nvidia — Perplexity confirmed it will deploy Vera in production, saying it finished AI coding workloads about 1.5x faster than conventional CPUs. Reuters, 2026-07-07, reported — three months old, found only because a search for the Modal story served this one.

Prime Intellect announced the Moondream acquisition itself on 19 October, having been reported on the 13th. Terms are undisclosed and Moondream had raised $4.5M, so still no node and no edge.

Still in talks

• Anthropic's IPO: the S-1 is still not on EDGAR, three days before the 23 October that a week-of-9-November roadshow would imply.
• Nscale's IPO: still no price range or share count, and Bloomberg reported that some investors want it priced well below the $30–35B it seeks.
• Stripe and OpenRouter: agreed in August, not closed; a headline today priced it at $7.5B on no source the map has not already weighed. Mark stays at the $7B floor.
• DeepSeek's second round, Amazon and Decart, NVIDIA and Reflection AI, Cohere and AISLE, Lambda, Mercor, Shield AI, Solidigm: checked, all unchanged.

Leads I could not verify

• Town's mark rests on search corroboration only. Neither techcrunch.com nor globenewswire.com resolves from this sandbox, so the company release was read through its title, date and figures as they appear in results. A human should open it: it does not say whether the $1B is pre- or post-money, an ambiguity the August coverage of the same round flagged.
• "GlobalFoundries to make AI chip parts for TSMC in $5bn deal" (Silicon UK, 19 October): every source from the 8–9 October original says $2B, which the map carries. Re-dated, figure inflated.
• "Nscale and Anthropic in talks for another $45B compute deal": that $45B is the deal Bloomberg and CNBC reported on 26 August and the map already draws. No new agreement.
• TypeSafe AI's "RMB5.8B Series A, 37-fold in 24 days": the same $870M a16z round, in yuan.
