Bitmain's latest publicly disclosed primary financing record is a USD 422,000,000 Series B dated August 4, 2018. The event is shown on the company page using the event date—not the date Captables published this historical profile.
Crimson Ventures is identified as lead investor. Other named participants include Temasek, Huangpu River Capital, JRR Group, SoftBank Group.
The preceding primary records in the ledger are USD 292,700,000 Series B dated June 1, 2018; USD 50,000,000 Series A dated September 4, 2017. These entries describe disclosed company financings; they do not include every secondary trade, employee tender, valuation mark or rumored transaction unless those events are separately labeled in the company ledger.
Bitmain is ranked number 19 in the Captables Private 100 source universe. It operates in Crypto Mining Hardware and is based in China. Its $18.0B ranking value is a third-party snapshot and should not be treated as a current executable share price or as the valuation for this round.
The round is currently supported by a public financing-database entry rather than an issuer filing, so Captables labels it as database-listed evidence. This page is a public-source reconstruction, not the issuer's stock ledger or legal capitalization table; undisclosed terms remain undisclosed and readers can submit stronger evidence for editorial review.
