> SoftBank Group executed the third and final $10 billion tranche of its February-announced OpenAI follow-on via Vision Fund 2 on October 1 (Japan time), completing $30 billion and bringing cumulative OpenAI investment to $64.6 billion (~13% ownership). Funded from September 24 foreign-currency senior notes — not bridge debt — SoftBank also canceled the remaining $10 billion undrawn under its March $40 billion bridge as of September 30.

The largest named OpenAI shareholder just finished the check it promised in February — and walked away from the bank bridge that financed the path there.

**SoftBank Group** announced that on **October 1, 2026 (Japan time)** it executed the **third and final USD 10.0 billion** tranche of its follow-on investment in **OpenAI Group PBC** via **SoftBank Vision Fund 2**, completing the **USD 30.0 billion** follow-on disclosed February 27. SoftBank’s **cumulative** OpenAI investment is now **USD 64.6 billion**, with ownership interest of approximately **13%**. **The Next Web** independently carries the same dollars, ownership, Vision Fund 2 vehicle, and bridge-exit frame.

## How it was paid — and what closed

The third tranche was funded with proceeds from **foreign currency-denominated senior notes** SoftBank announced on **September 24, 2026** — SoftBank’s primary is explicit that this is **not** further bridge draw. Effective **September 30, 2026**, SoftBank **canceled the remaining USD 10.0 billion** of undrawn capacity under the **March 27, 2026** bridge facility (total facility **USD 40.0 billion**). After that cancellation and the **September 9** early repayment SoftBank previously disclosed, **all borrowings under the bridge have been repaid and no undrawn commitments remain**.

Prior tranche chronology SoftBank lists: first tranche **April 1**, second **July 1**, third **October 1** — equal $10B legs of the February $30B commitment. TNW adds market color SoftBank’s primary does not rest on: the $30B as part of a larger OpenAI round context (Amazon / Nvidia commitments) and a Reuters-described bond raise size around the September notes. Prefer SoftBank’s disclosed **$64.6B / ~13% / Vision Fund 2 / notes-funded / bridge canceled** stack over secondary round framing.

## The financing trade

This is a **completion and ownership disclosure**, not a new commitment and not the earlier desk item on separate ~$30B / $1.4T bridge-round talk. SoftBank converts a multi-tranche follow-on into a finished stake figure and exits the bank facility that sat underneath it. For OpenAI capital-structure readers, the material facts are cumulative dollars, named ownership, and the vehicle — Vision Fund 2 — plus the clean bridge close.

## Limits

- Dollar amounts, ownership (~13%), Vision Fund 2 vehicle, notes funding, and bridge cancellation are from **SoftBank’s October 1 press release**; TNW corroborates the core stack.
- Round-context figures (Amazon/Nvidia commitments, $122B / $852B) appear in **TNW**, not SoftBank’s third-tranche release — treat as secondary framing.
- Ownership “approximately 13%” is SoftBank’s disclosure; dilution math beyond that statement is out of scope here.
- Distinct from excluded bridge-round rumor coverage and from SoftBank–OpenAI–SB Energy Stargate energy spend already on the archive.
