🔵 IEX Competitive Intel
NYSE National is updating its order routing and execution rulebook to formally designate the SIP data feed as its primary data source for handling, executing, and routing orders on the Texas Stock Exchange (TXSE), which is set to launch in July 2026. This is an immediate-effectiveness filing, meaning it takes effect automatically without requiring full SEC approval — it is a procedural housekeeping update rather than a substantive policy change. The practical consequence is that NYSE National will be ready to route orders to TXSE at launch, with no change to how market participants experience order handling today.
IEX RELEVANT TXSE's July 2026 launch as a new equity exchange entrant adds another competitor in the equity trading landscape, and incumbents like NYSE National are already preparing routing infrastructure for it, signaling that TXSE will meaningfully fragment order flow and require IEX to compete for volume in an even more crowded market.
24X National Exchange is extending by seven months (to December 27, 2026) the internal deadline by which it must formally file its rule change to launch overnight trading sessions (8 p.m. to 4 a.m.). The delay is needed because the Equity Data Plans — the consolidated tape infrastructure — won't be technically ready to handle overnight quote and trade data until around December 2026. This filing took effect immediately upon submission and does not kill or derail 24X's overnight trading ambitions; it simply buys time so 24X doesn't have to go through the costly exercise of removing and then re-filing its overnight session rules. For market participants, nothing changes today — overnight exchange trading from 24X remains on the horizon but is now realistically pushed to early 2027 at the earliest.
IEX RELEVANT 24X's overnight equity exchange session, if and when it launches, represents a potential new competitive front in U.S. equity exchange market structure that IEX will need to monitor, as it could attract order flow and liquidity into a time window where IEX currently has no offering.
NYSE Arca is adding a new 'Retail Tier 6' to its fee schedule, offering a $0.0035/share rebate for retail orders that add liquidity, targeted at broker-dealers who meet a combined equities volume threshold (0.075% of CADV) plus a meaningful options volume requirement (1.00% of TCADV) on NYSE Arca's affiliated options platform. This is a fee filing, so it takes effect immediately upon filing — the SEC can suspend it within 60 days but rarely does so for routine fee changes, meaning this will almost certainly stand. The practical effect is that NYSE Arca is sweetening rebates to pull retail order flow away from off-exchange venues and competing exchanges, particularly for firms that are active on both its equities and options platforms, while providing only modest fee relief on removing liquidity (free up to 65 million shares/month).
IEX RELEVANT NYSE Arca's cross-platform rebate bundling (equities + options volume requirements) intensifies the maker-taker rebate arms race for retail order flow, directly pressuring IEX's ability to attract retail-tagged orders given IEX's no-rebate, investor-protection-oriented fee model.
