Twenty-two stock issuers have now exercised their right to block third-party tokenized versions of their shares on OKX's tokenization platform, up from 16 earlier this week. The blocking mechanism operates under the SEC's tokenized-stock exemption framework, which grants companies the authority to prevent unauthorized tokenization of their equity. The rapid increase in issuer opt-outs highlights growing corporate pushback against uncontrolled tokenized securities as exchanges expand digital asset offerings tied to traditional equities.
