NYSE's move into stock tokenization with 24/7 trading capability marks a significant shift in how traditional markets operate. The notable aspect here is their decision to build proprietary technology rather than leverage existing blockchain infrastructure. This approach raises interesting questions about the future trajectory of the broader market. If major institutions continue developing in-house solutions, we may see a divergence in how tokenization develops across different asset classes. For investors holding RWA-focused tokens, this independent path taken by major exchanges could reshape market dynamics and portfolio considerations worth monitoring closely.
