Trading session local time · America/New_York
Session hours and the settlement cycle are compiled by Finance Foundation from the venue’s own published trading calendar. These are exact and change-prone — an extended session or a moved auction dates a figure like this quickly — so each row below carries what two independently maintained open calendars say about the same venue. Verify against the exchange before relying on any of it operationally. Sources.
exchange_calendars return the same hours as we hold. Cross-check from exchange_calendars (Apache 2.0) and pandas_market_calendars (MIT); neither endorses this site.

549300L8X1Q78ERXFD06 - Ultimate owner
- None above it — NASDAQ, INC. is the top of its own ownership chain.
GLEIF records no parent for this entity (NO_KNOWN_PERSON), so the operator is itself the top of the tree - Sibling venues
- Nasdaq Stockholm (OMX Stockholm), Nasdaq Copenhagen, Nasdaq Helsinki — run by the same group
- Owner listed
- NDAQ on Nasdaq Stock Market
Self-listed — its own shares trade on a market it operates. - Who holds it
- Dispersed, but with three near-10% blocks that are unusual for a US exchange group — Vanguard 10.5%, Investor AB 10.3% and Borse Dubai Limited 10.3% — and Nasdaq's charter caps any shareholder's votes at 5% of total voting power regardless of holding.
Clearing and settlement
| Institution | Role | LEI |
|---|---|---|
| DTC — The Depository Trust Company | Central securities depository | 549300HBJLRO8YFMI370 |
| NSCC — National Securities Clearing Corporation | Central counterparty | 549300RYC9NELN2ICA34 |
These are separate legal entities from the venue operator above, each with its own LEI — a distinction the ISO 10383 registry itself gets wrong for two venues in this dataset, where it records the depository's or the clearing house's code against the exchange. The full layer.

Operating MIC vs segment MIC per ISO 10383: the operating code identifies the exchange, segment codes identify its individual order books, growth markets and derivatives venues. Every code was checked line by line against the official ISO 10383 registry file (SWIFT is the registration authority) — codes that were expired or belonged to a separate operating venue were rejected.
