Bitmain's draft Hong Kong listing application proof, pages 136-137 and 142, reports three preferred-share subscriptions totaling $784.75M: $50M Series A completed in two August 2017 stages, $292.7M Series B completed in three stages by July 6, 2018, and $442.05M Series B+ completed August 20, 2018. These are issuer-described consideration amounts, not the imported $422M latest round or an additional June $292.7M and August $422M pair. The imported dates were not legal closing dates. The filing lists specific investor vehicles; pooled company-level backers are not assigned to any individual round. Temasek's August 2018 public denial of investing in Bitmain conflicts with the filing's statement that two B+ holders were beneficially owned by Temasek; their relationship requires editorial adjudication, not an unsupported simplified attribution. This 2018 draft is not a current cap table or proof that no later financing occurred.
