New York is basically the pulse of global finance. It's loud, expensive, and relentless. If you've spent any time near Times Square or the Financial District, you know that the tall glass buildings aren't just for show—they house the machinery that keeps the world’s money moving. Right in the middle of this chaos sits the LSEG New York office, a space that represents a massive shift in how the London Stock Exchange Group views itself. They aren't just "the exchange" anymore. Honestly, since the Refinitiv acquisition, LSEG has transformed into a data and tech titan that just happens to have a very famous trading floor back in London.
The New York presence is huge.
It has to be. You can't claim to be a global leader in financial markets infrastructure if you don't have a massive footprint in Manhattan. The office isn't just a satellite location; it’s a nerve center. It's where the massive data feeds from across the Americas get processed, where the indices are managed, and where some of the most complex post-trade services are engineered.
Why the Location at 28 Liberty Street Matters
For a long time, LSEG's New York operations were scattered. That's what happens when you grow through acquisitions like FTSE Russell and Refinitiv. You end up with teams in different buildings, different cultures, and different vibes. But the move to 28 Liberty Street changed that. This isn't just a random office building. It’s a landmark.
Formerly known as One Chase Manhattan Plaza, 28 Liberty is a skyscraper that screams "Old School Finance" but has been gutted and rebranded for the digital age. It's 60 stories of steel and glass. LSEG taking up significant floorspace here wasn't just a real estate move; it was a statement of intent. They wanted their people together. When you put the data scientists from the analytics teams in the same elevator as the sales guys dealing with big investment banks, things actually start to move faster.
The view is pretty wild, too. You’re looking out over the harbor, seeing the statue, and feeling like you're actually at the center of the world. But inside, it’s surprisingly tech-focused. You won't see a lot of mahogany desks or dusty portraits. It’s open-plan, heavy on the monitors, and designed for collaboration.
The Refinitiv Ripple Effect
You can't talk about the LSEG New York office without mentioning the $27 billion deal for Refinitiv. That was the moment everything changed. Before that, LSEG in New York felt a bit like a British company trying to make it in America. After the deal, they suddenly owned the Eikon terminals (now Workspace) that sit on almost every trading desk in the city.
Suddenly, LSEG was the primary competitor to Bloomberg.
In the New York office, this meant a massive influx of talent. We're talking about thousands of employees globally, with a significant chunk based right here in NYC. These are the people responsible for the real-time data feeds that power the world's algorithmic trading. If the New York office has a "bad day," the financial markets feel it. It’s high-stakes stuff.
Interestingly, the culture in the New York office is a bit of a hybrid. You have the grit and "get it done" attitude of New York finance mixed with the slightly more structured, methodical approach of a legacy British institution. It’s a weird mix, but it seems to work. People are working on things like LSEG Workspace, which is their flagship platform. It’s basically their answer to the Bloomberg Terminal, and a lot of the development and client support for the US market happens right here in the city.
Breaking Down the Tech Stack in Manhattan
What are they actually doing in there? It's not just shouting into phones.
- Data Analytics and FTSE Russell: A lot of the people in the New York office are focused on indices. If you've ever tracked a "small-cap" fund, you're likely looking at a FTSE Russell index. The researchers and analysts in NYC spend their days crunching numbers to decide which companies belong in which index. This determines where billions of dollars of institutional money flows.
- Post-Trade Services (LCH): This is the "plumbing" of the financial world. Clearing and settlement. It sounds boring until you realize that without it, the whole system collapses. The LCH (London Clearing House) team in New York handles a massive volume of US Dollar interest rate swaps.
- Capital Markets: Yes, they still help companies go public and raise money. Even though the primary exchange is in London, the New York team is crucial for cross-border listings.
The Microsoft Partnership: A New Era
Here's something most people miss: LSEG is basically becoming a cloud company.
Their massive partnership with Microsoft is fundamentally changing what happens inside the LSEG New York office. They are moving their entire data infrastructure to Azure. This isn't just a "save to the cloud" project. It’s about using AI and machine learning to make financial data more accessible.
Imagine being a trader in New York and having your data tools integrated directly into Microsoft Teams. That’s the goal. The New York office is a testing ground for these integrations. They have engineers working closely with Microsoft’s US-based teams to figure out how to make a Excel spreadsheet "smart" enough to predict market trends.

It’s a long way from the days of hand-written ledgers.
Sustainability and the "Green" Push
You’ll hear the word "ESG" (Environmental, Social, and Governance) a lot if you hang around 28 Liberty Street. LSEG has positioned itself as a leader in green finance. They aren't just reporting on it; they are creating the standards.
The New York office houses a lot of the team responsible for ESG data. They are the ones digging into company reports to see if a firm is actually reducing its carbon footprint or just "greenwashing." Because NYC is the hub for US asset managers (the people who run your 401k), having the ESG experts in the same time zone as BlackRock and Vanguard is a huge tactical advantage.
A Day in the Life: The Vibe Check
If you walked into the office today, you'd notice a few things. First, it’s not a "suit and tie" environment anymore. It’s "smart casual," leaning heavily toward the casual side if you're on the tech team.
There's a lot of caffeine.
The pantry areas are usually buzzing. New Yorkers love to network, and the LSEG office is no different. You'll see people from the "Data & Analytics" division grabbing coffee with someone from "Risk" or "Post-Trade." This cross-pollination is exactly why they spent the money to consolidate into one big flagship office.
There’s also a heavy emphasis on "Global Diversity." You’ll hear a dozen different accents in a single afternoon. It reflects the city, but it also reflects the company’s reality. They are a British company, with a massive US presence, serving clients in Asia, Europe, and the Middle East.
Addressing the Misconceptions
People often think LSEG is just a stock exchange. That is probably the biggest mistake you can make.

In reality, the "Exchange" part of the London Stock Exchange Group is a relatively small part of their total revenue. They are a data company now. The New York office proves this. If you stripped away the "Exchange" name, you’d be left with one of the largest financial technology and data providers on the planet.
Another misconception is that the New York office is just a sales floor. It's not. There are deep technical roles here. They are hiring developers, cybersecurity experts, and AI specialists. They are competing with Google and Amazon for talent, not just Goldman Sachs.
The Competitive Landscape
LSEG doesn't have it easy in New York. They are fighting on several fronts.
- Bloomberg: The reigning king of the terminal. Everyone in the New York office knows they are the underdog here, but they are playing the long game with the Microsoft partnership.
- ICE (Intercontinental Exchange): They own the New York Stock Exchange. There's a natural rivalry there, especially in the data space.
- S&P Global: Another massive player in the world of indices and data.
The New York office is the frontline of these battles. Every time an LSEG salesperson wins a contract with a mid-sized hedge fund in Greenwich or a big bank on Wall Street, it’s a win for the Manhattan team.
How to Engage with LSEG in New York
If you’re a professional in the city, there are a few ways you actually interact with this office without realizing it.
If you use a financial news app, the data behind the charts might be coming from an LSEG feed. If you work in a back-office role at a bank, you might be using their clearing services every single day.
For those looking to work there, the New York office is known for having a pretty rigorous hiring process. They want people who understand the "why" behind the numbers. It’s not enough to be good at Python; you have to understand how a shift in interest rates by the Fed is going to impact a portfolio of emerging market bonds.

What’s Next for the NYC Presence?
The LSEG New York office is only going to get bigger and more integrated. As the Microsoft partnership matures, expect to see even more "tech-first" roles opening up in 28 Liberty.
They are also leaning heavily into private markets. Most of the "action" in finance lately has been in private equity and private credit, rather than public stocks. LSEG is building out tools to bring transparency to these murky markets, and New York is the epicenter of that effort.
It’s a fascinating time for the company. They’ve successfully navigated the transition from a traditional exchange to a modern data powerhouse. And they’ve done it while planting a very firm flag in the middle of Manhattan.
Real-World Action Steps for Finance Professionals
If you’re looking to leverage what LSEG offers in the New York market, start here:
Evaluate Your Data Stack
Don't just stick with what you know because "that's how we've always done it." LSEG Workspace has made massive strides in the last two years. If you haven't seen a demo recently, you’re missing out on some significant AI-driven search capabilities that are honestly ahead of some of the older competitors.
Focus on the Microsoft Ecosystem
If your firm is already an "Azure shop," look into how LSEG data can be piped directly into your existing environment. The friction of moving data between platforms is disappearing. The New York teams are specifically trained to help firms integrate these "data-as-a-service" models.
Watch the Index Shifts
Keep a close eye on FTSE Russell’s rebalancing announcements. Because these are managed and supported out of the New York and London hubs, the insights coming out of their NYC research teams can give you a head start on where passive fund flows are headed.
Network at 28 Liberty
LSEG often hosts industry events and "thought leadership" sessions in their New York space. If you get an invite, go. It’s one of the best ways to see the tech firsthand and meet the people who are actually building the tools you use every day.
The LSEG New York office isn't just a building; it’s the physical manifestation of a company that refused to be left behind by the digital revolution. Whether you're a trader, a developer, or just an observer of the markets, what happens on those floors at 28 Liberty matters. It’s where the future of financial data is being written, one line of code at a time.
