Lead summary / Short answer

Short answer: the historic, independent Chicago Stock Exchange no longer operates as a standalone, Chicago‑based floor exchange. The trading venue was acquired by Intercontinental Exchange (ICE) in 2018, rebranded and operated under the NYSE Group as NYSE Chicago, and — following NYSE/ICE announcements in early 2025 — the electronic trading platform was moved and legally reincorporated as NYSE Texas and relaunched as a fully electronic equities exchange in 2025. ICE/NYSE continue to hold corporate and certain business operations in Chicago even after the venue’s relocation.

To restate the query for search clarity: does the chicago stock exchange still exist? The historic institution exists in archival, regulatory, and cultural forms, but not as an independent, Chicago‑based national securities exchange operating under the original Chicago Stock Exchange name.

History

Founding and 19th‑century origins (1882)

The Chicago Stock Exchange traces its founding to March 21, 1882, when local brokers established a market to serve the city’s growing industrial and railroad economy. Early membership consisted of Chicago merchants, brokers and financiers who traded local industrial, railroad and utility securities that underpinned Midwestern growth. The original exchange served as an important regional hub for equities trading at a time when New York, Philadelphia and Boston dominated the national landscape.

As of March 21, 1882, the exchange began operations in downtown Chicago and later settled into prominent locations on LaSalle Street, joining the city’s financial district alongside grain and futures institutions.

20th‑century growth and Midwest consolidation (1900–1993)

Over the 20th century, the Chicago Stock Exchange participated in Midwest consolidation trends. Regional markets evolved, merged and restructured to manage competition from larger national exchanges and to rationalize listing and trading services.

Mid‑century developments included cooperative agreements with other regional exchanges and periodic changes in governance to modernize trading and regulatory compliance. At one point, the Midwest Stock Exchange and related organizations reflected broader consolidation of regional U.S. securities trading venues.

Return to Chicago Stock Exchange name and modernization (1993–2005)

In 1993 the exchange readopted the Chicago Stock Exchange name, signaling an effort to reassert a distinct regional brand while investing in technology. In the 1990s and early 2000s the venue implemented automated execution systems, embraced electronic order‑matching technology, and expanded product types to include exchange‑traded funds (ETFs) and other modern equity instruments.

These upgrades positioned the exchange to serve institutional and electronic participants as U.S. equity trading shifted from open outcry floors to networked electronic markets.

Demutualization and business restructuring (2005–2010s)

In 2005 the Chicago Stock Exchange changed its corporate structure from a member‑owned mutual organization to a for‑profit corporate entity. This demutualization aligned the exchange with industry peers that converted ownership structures to raise capital, enable acquisitions, and better compete in an increasingly national and electronic market.

During this period the exchange focused on carving out market niches, improving technology stacks, and offering listing and execution services designed to attract specialist liquidity providers and institutional order flow.

Acquisition by Intercontinental Exchange (ICE) and rebranding as NYSE Chicago (2018–2019)

ICE acquired the Chicago Stock Exchange in July 2018. As part of ICE/NYSE Group integration, the exchange was folded into the NYSE regulatory and operational framework and rebranded to operate as NYSE Chicago. The venue’s trading model shifted further toward a fully electronic matching engine, positioning it as a specialized venue within the NYSE Group portfolio rather than an independent regional exchange with a large physical trading floor.

As of July 16, 2018, according to ICE press materials, the acquisition aimed to extend NYSE Group’s reach in U.S. equities markets while rationalizing technology and regulatory compliance across its exchanges.

Relocation/reincorporation as NYSE Texas (2025)

In early 2025 NYSE/ICE announced plans to move and legally reincorporate the electronic exchange previously operating in Chicago to Texas. Public announcements in February–March 2025 stated that the trading platform and regulatory market functions would be transferred, and the venue relaunched as NYSE Texas, a fully electronic equities exchange headquartered and incorporated in Dallas. The stated rationale included closer ties to a growing Southwest economic base, Texas’s business climate, and strategic access to a different corporate and investor ecosystem.

As of March 5, 2025, according to an NYSE/ICE press release, the transfer was timed to allow regulatory filings, SEC notifications and member onboarding before NYSE Texas began regular operations later in 2025.

Organizational and regulatory status

Ownership and corporate structure

The trading venue that began life as the Chicago Stock Exchange is owned by Intercontinental Exchange (ICE) through its NYSE Group subsidiary. ICE’s corporate acquisition and later organizational decisions meant that the exchange’s brand, technology and regulatory permissions moved into a larger corporate group structure.

The 2025 move required legal steps to reincorporate the exchange in Texas. That process involved amending organizational charters, updating governance documents, and notifying stock exchange members and the SEC of changes to the exchange’s registration and domicile.

Regulatory oversight and SRO status

Historically, the Chicago Stock Exchange operated as a national securities exchange under SEC oversight and functioned as a self‑regulatory organization (SRO) with delegated regulatory responsibilities. Any material change — including acquisition, rebranding, relocation or changes to market structure — required SEC filings and, in many cases, SEC approval.

As of early 2025, NYSE/ICE submitted required notices and filings to the SEC to effect the relocation and reincorporation of the exchange to Texas. These filings are typical when an exchange changes its legal domicile or undertakes a significant structural transition and are subject to SEC review and public comment periods.

Operations, market role, and products

Electronic trading platform and market niche

Under ICE/NYSE ownership the former Chicago exchange operated as a fully electronic matching system. The venue focused on high‑speed execution, block trading capabilities and providing a venue attractive to certain market participants — including institutional traders, hedge funds and market makers — who seek low latency, predictable fee schedules, and specialized order types.

The exchange’s niche included offering alternative order types, rebates / fee tiers to liquidity providers, and protocols to attract internalization of large trades. After reincorporation as NYSE Texas, the venue continued to present itself as a modern, electronic equities market within the NYSE Group ecosystem.

Market share and trading volume

Historically the Chicago Stock Exchange held a relatively small share of total U.S. equities trading. Typical figures cited over many years put the venue’s average daily market share below 0.5% of consolidated U.S. equities volume — a modest footprint relative to dominant national exchanges. Trading volume and market share varied day‑to‑day and across product types, with peaks occurring when specific listing or routing incentives attracted flow.

As of early 2025, regulators and market data providers reported that the NYSE Group’s combined venues continued to handle a substantial portion of U.S. equities volume while the specific NYSE Chicago / NYSE Texas venue represented a niche slice of that total. Quantifiable daily share percentages and dollar volumes are reported in exchange market reports and consolidated tape datasets; readers should consult official market data releases for precise, dated metrics.

Listings and dual‑listing model (transition to NYSE Texas)

The exchange historically used a dual‑listing and tiered listing model for certain securities. Small and mid‑cap companies sometimes utilized regional exchanges in combination with national platforms to facilitate liquidity and visibility. Under NYSE Group ownership, listing mechanics aligned with broader NYSE policies, offering options for companies to list on NYSE pillars while permitting trading on multiple NYSE‑operated platforms.

With the transition to NYSE Texas, listing sponsors and issuers were given clear guidance on how securities could trade on the new venue and how dual‑listing arrangements would be handled. Representative securities that traded on the old NYSE Chicago platform were transitioned to be available for trading on NYSE Texas under the NYSE Group’s consolidated rules.

Physical presence, buildings and legacy

Chicago locations and historic building

The Chicago Stock Exchange’s historical presence on LaSalle Street — and its association with Chicago’s financial center — left a physical and cultural mark. The exchange’s old trading‑floor heritage, architectural footprint and public visitor references were part of Chicago’s economic narrative. Even as trading moved electronic, the exchange’s building and legacy artifacts remained points of local historical interest.

Some elements of the historic trading floor and visitor gallery were preserved or archived; others were repurposed as office space or museum material reflecting the city’s financial past.

Impact on the Chicago financial community

The relocation of the exchange’s trading venue and its legal reincorporation as NYSE Texas represented a symbolic loss to some Chicago stakeholders. Local officials and business groups noted the departure of a long‑standing exchange brand from the city’s financial district. At the same time, ICE retained certain business lines and offices in Chicago, preserving jobs and continuing some institutional functions in the city.

Local reaction included commentary on economic symbolism, while Texas officials publicly welcomed the new corporate domicile and the jobs tied to operations.

Reactions, implications and broader market context

Local economic and political reactions

Chicago stakeholders expressed mixed reactions. Some saw the move as a loss of a historical brand and potential symbolic blow to the city’s financial standing. Business advocacy groups and local politicians noted concerns about jobs and the cultural significance of LaSalle Street institutions.

Conversely, Texas officials and local business leaders welcomed the relocation. As of March 2025, press statements from Dallas and Texas economic development agencies framed the move as evidence of the state’s growing financial and corporate attractiveness.

Competitive and regulatory implications

The relocation and reincorporation reflect broader trends in U.S. markets: exchanges are increasingly electronic, corporate domiciles shift to reflect tax, regulatory and business climates, and regional centers vie to attract financial infrastructure.

For issuers and market participants, the move had limited direct operational disruption because trading had long been electronic and distributed. Regulatory oversight continued under SEC jurisdiction — regardless of state corporate domicile — but the exchange’s SRO responsibilities and filings required updates to reflect the new corporate home.

The development also fed conversations about whether other regional or state‑based exchanges would emerge and how states like Texas are positioning themselves as alternative centers for corporate and financial services.
