Every Neuralink financing since its first SEC filing in 2017, with the amount taken from Neuralink’s own SEC Form D filings and the round names and investors from Neuralink’s announcements. Neuralink has never published a valuation; the only one shown here is the reported ~$9B pre-money for the 2025 Series E, and it is labelled as reported.

Amounts from SEC Form D (“total amount sold”). Neuralink has disclosed no valuation, so there is no step-up column and no multiple.

Still private, and valuations are mostly unofficial: Neuralink has never stated a valuation. The only figure in this table is the reported ~$9B pre-money for the Series E. Higher figures reported since (talks about a new round, and secondary-market quotes) are not confirmed by Neuralink or an SEC filing, so they are not rows. No new Form D has been filed since June 2025 (SEC EDGAR, checked 13 Nov 2026).

Methodology & status definitions

How each row is labelled and calculated.

Closed round

A financing Neuralink announced or reported to the SEC on Form D, with new money to the company. Amounts are the Form D “total amount sold”; rounded figures match Neuralink’s announcements.

Valuation ÷ run-rate

Valuation ÷ the run-rate the company stated in that announcement (GNF calc.). Neuralink has not stated revenue or a run-rate, so no multiple is shown.

What is not a separate row

Reported talks without an SEC filing or company confirmation (for example the April 2025 Bloomberg report of a raise at $8.5B pre-money, and 2026 reports of a round at a higher valuation). Secondary-market prices. Grants and partnerships.

Updates & corrections
