Panthalassa Funding: Series B and NAVER Investment

Panthalassa announced a $140 million Series B led by Peter Thiel on May 4, 2026. NAVER announced a further investment relationship on August 13, without disclosing an amount or round label. The source-backed record therefore includes both events while leaving the later investment size unresolved.

Verified October 7, 2026. Four evidence records covering the Series B, returning-investor context, approximate dated valuation commentary and NAVER’s subsequent investment. They are not four financing rounds.

The $140 million Series B

The company-authored May announcement identifies Peter Thiel as lead and describes plans to complete a pilot manufacturing facility near Portland and accelerate Ocean-3 deployment.

It names Founders Fund, Gigascale Capital, Lowercarbon Capital, Unless and WovenEarth as returning investors. Their participation does not disclose each investor’s check size or a full earlier-round history.

NAVER’s August investment announcement

The August 13 NAVER release establishes an investment in Panthalassa after the May announcement. It does not state the investment amount or financing-round label.

An undisclosed amount should remain blank. It would be inaccurate to repeat the $140 million Series B as NAVER’s own investment or assign the August event to a newly invented round.

How to interpret the near-$1 billion valuation

NAVER’s background on the May financing describes a valuation approaching $1 billion. That is approximate, dated investor commentary, rather than a precise current valuation or a separate amount of cash raised.

The workbook retains the source, date and valuation context. It does not combine the valuation with financing proceeds or treat the estimate as an October 2026 market price.

Deployment plans and funding totals

The August release describes Ocean-3 deployment in 2026 and commercialization in 2027 as plans. The announcement itself does not establish completed deployment or commercial operation.

Likewise, the reviewed announcements do not establish a complete lifetime fundraising total. The selected financing evidence supports the reported Series B and later undisclosed investment without relying on an unverified database sum.
