What Changed

  • New SEC postings are routine 424B2 prospectus supplements and 10-Ks from non-crypto issuers (Citigroup, Goldman Sachs, and several banks/industrial filers) with no references to Bitcoin ETFs, creations/redemptions, or custody movements [1][2][3][4][5][6].
  • No DTCC/NSCC, ETF sponsor, or custodian disclosures appeared in the window.

Cross-Source Inference

  • Observed facts: Only non-crypto 424B2/10-K filings were posted; none mention crypto ETF flows or custody [1][2][3][4][5][6].
  • Assessment: There is still no primary-market evidence linking the BTC >$70k move to ETF creations/redemptions or custodian inflows (confidence: high), as the available official sources are unrelated and silent on such activity.

Implications and What to Watch

  • Maintain attribution as unconfirmed until:
  • DTCC/NSCC clearing data or ETF sponsor press releases show creations/redemptions.
  • Custodian (e.g., Coinbase Custody, Fidelity Digital Assets) wallet inflows are identifiable on-chain.
  • Next checks: DTCC/NSCC postings, ETF provider websites/press feeds, custodian status pages, and known custodian/AP address clusters. Citigroup/Goldman filings today are not probative for crypto ETF flows and can be deprioritized [1][2][3].
