🔵 IEX Competitive Intel
LTSE is updating its rulebook to add the Texas Stock Exchange (TXSE) data feeds to its list of market data sources used for order handling, execution, and surveillance, reflecting TXSE's planned July 6, 2026 trading launch, and to rename Nasdaq BX to Nasdaq Texas. The SEC allowed the filing to take effect immediately as a non-controversial administrative change, waiving the usual 30-day delay, so it is already operative and cannot be blocked absent an unlikely SEC suspension within 60 days. For market participants, nothing changes operationally at LTSE beyond LTSE now consuming TXSE's feed once TXSE goes live — the real signal here is the confirmation that TXSE is entering the equity exchange market.
IEX RELEVANT Confirms the imminent launch of the Texas Stock Exchange as a new equity exchange competitor, signaling further fragmentation of U.S. equity market share that IEX also competes for.
NYSE-family exchanges add IEX Options connectivity and reorganize Cboe feeds at Mahwah
NYSE National, NYSE Arca, NYSE, NYSE Texas, and NYSE American each filed immediately effective changes to their Mahwah colocation connectivity fee schedules, adding a connectivity option for IEX's forthcoming IEX Options data feed at $1,300/month (matching the existing IEX Equities fee) and reorganizing Cboe third-party feeds by asset class rather than by market. All are routine 19b-4(f)(6) filings with no price increases, subject to a 60-day SEC suspension window. Filings are dated July 6-7, 2026 and are otherwise substantively identical across the five NYSE-family venues.
IEX RELEVANT The NYSE family is preemptively enabling colocation connectivity to IEX's new options exchange ahead of its October 2, 2026 launch, easing market participant access and supporting IEX's expansion beyond equities into options.

🟠 Other Notable Filings
FINRA proposed to overhaul short-selling transparency by increasing the frequency and granularity of short interest reporting (Rule 4560) and creating a new Rule 4321 requiring firms to report daily allocations of fail-to-deliver positions to correspondent firms on a monthly basis. The SEC did not approve or reject anything here — it simply gave itself more time to decide, pushing its deadline from July 2 to August 14, 2026; this is a routine procedural extension, not a signal of trouble for the proposal, which can still be approved, disapproved, or sent to further proceedings. Nothing changes for market participants yet, but if ultimately adopted, broker-dealers would face enhanced short-interest and fail-to-deliver reporting obligations.
