24X National Exchange is asking the SEC for a temporary exemption from consolidated market data reporting requirements so it can launch overnight trading (9 PM–4 AM ET, Sunday–Thursday) before the equity SIPs (consolidated tape infrastructure) are upgraded to handle overnight hours — a technology upgrade not expected until December 2026. The SEC is publishing the request for public comment, which is a procedural step that neither approves nor kills the proposal; the outcome depends on comment feedback and the Commission's judgment. If granted, 24X could begin overnight exchange trading without full consolidated quote/trade data dissemination, relying instead on its own proprietary data feed — a significant market structure precedent that could reshape how and when U.S. equities trade.
IEX RELEVANT This is highly relevant to IEX for several reasons. First, if 24X gains approval to operate an overnight session, it could capture a first-mover advantage in a new trading window before any other exchange — including IEX — is positioned to compete there. Second, the SEC's comment question explicitly asks whether other exchanges with overnight trading rules should be allowed to use the same exemption, meaning this could open the door for all exchanges (including IEX) to consider overnight operations, fundamentally expanding the competitive landscape. Third, overnight trading without consolidated SIP data creates a fragmented, lower-transparency environment that cuts against IEX's core brand positioning around investor protection and market quality — IEX may want to comment opposing or conditioning the exemption. Finally, if incumbent 'more established' exchanges (NYSE, Nasdaq, Cboe) react by launching overnight ATSs, the entire competitive dynamic shifts, potentially forcing IEX to accelerate its own strategic decisions about extended-hours trading.
Nasdaq filed a proposal in late December 2025 to extend its U.S. equities trading hours to 23 hours a day, five days a week — a dramatic expansion from the current 9:30am–4:00pm core session plus limited pre/post-market hours. The SEC is not acting yet; it is simply taking more time (extending its review deadline from February 27 to April 13, 2026) to study the proposal more carefully before deciding to approve, disapprove, or open a formal review process. This is a procedural step, not a substantive judgment — the proposal is still alive and nothing changes for market participants yet, but the SEC's decision to slow down signals the complexity and significance of the issue.
IEX RELEVANT Extended trading hours at Nasdaq would represent one of the most significant structural changes to U.S. equity market operations in decades and directly affects IEX's competitive positioning. If Nasdaq wins approval, IEX would face pressure to match extended hours or risk ceding market share to Nasdaq during the new trading windows. IEX's speed bump and investor protection differentiators were designed around the current market structure; a near-24-hour session would introduce new liquidity fragmentation, wider spreads, and potential manipulation risks during low-volume overnight periods — areas where IEX could either differentiate further or struggle operationally. IEX would need to decide whether to follow with its own extended hours proposal, potentially diluting its focused value proposition, or hold its current hours and accept a narrower addressable market.
🔵 IEX Competitive Intel
IEX is tweaking its Incremental Fee Tier program — a volume incentive launched in September 2025 that rewards members for growing their non-displayed trading on IEX with a discounted fee of $0.0001/share (vs. the standard $0.0010/share). Specifically, IEX is making it easier for its heaviest displayed liquidity providers (Tier 7 and Tier 8 members) to also qualify for the non-displayed discount by lowering the required volume hurdle from 15M to 10M shares ADV, and separately, doubling the cap on discounted volume for any member that has qualified for the program for three consecutive months. As a fee change, this took effect immediately upon filing on March 1, 2026 — no SEC approval needed, though the SEC retains the right to suspend it within 60 days. In practice, this slightly sweetens IEX's fee incentives for its largest, most active members to deepen both displayed and non-displayed liquidity pools on the exchange.
IEX RELEVANT This is IEX's own fee filing, so it is directly relevant as a first-party competitive action rather than a threat or opportunity from a rival. IEX is actively tuning its volume incentive program to attract more non-displayed flow and retain high-volume displayed liquidity providers, which supports its market share growth strategy. The linkage between top displayed rebate tiers (Tier 7/8) and easier access to the non-displayed fee discount is a deliberate attempt to bundle IEX's displayed and non-displayed liquidity incentives — making IEX stickier for large brokers who route both types of flow. This matters for IEX's competitive positioning because non-displayed liquidity (midpoint trades, discretionary pegs, etc.) is central to IEX's value proposition as a venue built around investor protection and anti-gaming mechanics. Growing that pool strengthens execution quality, which in turn is a key differentiator versus maker-taker competitors.
