Analyzed Economic Effects

2 provisions identified: 0 benefits, 1 costs, 1 mixed.

Trading Platform Definition Expanded

On September 1, 2026 BYX proposed changing the Fee Schedule definition of “Trading Platform” to add “a similar order-matching execution venue or decentralized platform (including blockchain-based or tokenized environments).” That change means functionally equivalent venues that were not previously listed (for example, single-dealer platforms or decentralized order-matchers) can be treated as a Trading Platform and be subject to the Exchange’s applicable fees (the filing notes an example where a Trading Platform pays $2,000/month for BYX Depth for Non-Display Usage versus $1,000/month for a non-Trading Platform).

Similar Venues Treated Alike For Fees

The Exchange says the amended definition is intended to ensure that functionally equivalent order-matching venues are treated consistently and that fees and charges are allocated equitably among Members and other persons using its facilities. The filing cites Section 6(b)(4) and 6(b)(5) of the Exchange Act as the statutory basis for ensuring equitable allocation and avoiding unfair discrimination.
