The Chicago Board Options Exchange (CBOE) has officially submitted a 19b-4 form, signaling a major step towards launching the Canary Capital SUI ETF. This filing, an exchange rule change request, is a crucial regulatory hurdle for any new ETF seeking to trade on a national exchange. While details surrounding the Canary Capital SUI ETF remain scarce, the CBOE's involvement suggests a growing institutional interest in offering investment products tied to the SUI blockchain ecosystem. Investors are eagerly awaiting further information regarding the ETF's specific investment strategy, underlying assets, and potential benefits. The SEC will now review the 19b-4 filing, a process that could take several weeks or months before a decision is reached. ```
