Most people encounter a financial exchange as a flicker: a price moves, an order fills, a closing bell appears on television. The machinery underneath is faster, denser and less visible. Matching logic, allocation models, risk protections, market data, regulation and customer support work together in fractions of a second. Kelli Annequin has spent more than 25 years giving that machinery a public language. Her career runs through exchanges, trading firms, a global bank and an index provider. At MIAX, where she is Senior Vice President and Chief Marketing Officer, the assignment is both simple to say and difficult to execute: make a growing group of markets feel like one company without sanding away what makes each market distinct.
This is a particular kind of executive work. A CMO in consumer goods can hold up the product. At an exchange, the product is partly code, partly rules, partly trust and partly the accumulated behavior of everyone who shows up. A single corporate portfolio can include options exchanges with different pricing and priority models, an equities venue, a futures market and international exchanges operating under their own histories and regulatory frameworks. The language has to be accurate enough for market professionals and clear enough for everyone else. Too much compression makes the claim empty. Too much detail turns the message into a manual.
A career built inside the machinery
Annequin did not arrive at that problem from the edge of finance. Before MIAX, she held senior leadership roles at MSCI, UBS, Convergex, Jane Street, KCG, Citi, Susquehanna International Group and the Philadelphia Stock Exchange. The sequence matters because it crosses several viewpoints in the market. An exchange thinks about venue design and participants. A trading firm thinks about execution. A bank thinks about clients and capital. An index business turns market information into products used across the investment world. The institutions change, but the central problem remains: how do you describe a complicated financial capability in a way that is precise, useful and memorable?
Her education supplied another pair of lenses. Annequin earned a bachelor's degree from Temple University and completed an Executive Education program in marketing at the Wharton School of the University of Pennsylvania. Those credentials are the compact version. The longer education is the resume itself, a route through the institutions that built, traded on, sold access to and measured modern markets. By the time MIAX recruited her in 2023, she had more than two decades of context for reading what an exchange operator says, what its customers hear and where the two can drift apart.
MIAX created the chief marketing officer position when Annequin joined. That detail is easy to pass over, but it defines the mandate. She was not simply inheriting a fixed brand machine. She was asked to oversee global marketing and branding as the business widened. At the time, MIAX's holdings already extended beyond its original options footprint. The company needed a story broad enough to hold multiple asset classes and geographies, then specific enough to help each business reach its own audience.
The brand has to keep up
A useful way to understand Annequin's MIAX chapter is through two assignments that arrived early. One was the launch of MIAX Sapphire, the group's fourth U.S. options exchange. The other was the renaming of the Minneapolis Grain Exchange, known as MGEX, as MIAX Futures. One project introduced a venue. The other brought a historic institution more visibly into a wider family. Both demanded more than a new label. Launching means explaining where a venue fits and whom it serves. Rebranding means preserving recognition while changing the frame around it.
The two projects also reveal the hidden work of a portfolio brand. MIAX Options, Pearl, Emerald and Sapphire are not interchangeable names pasted on identical venues. Their models differ. Equities and futures bring different market structures. The Bermuda Stock Exchange and The International Stock Exchange extend the map beyond the United States. A coherent identity cannot depend on pretending these differences do not exist. It has to make the differences navigable, while giving customers a reason to connect them to the same operating standard.
“I want to thank Markets Media for highlighting the achievements of women in our industry. It's an honor to be recognized among such an esteemed group of professionals.”Kelli Annequin, 2024
Markets Media recognized that work in November 2024, giving Annequin its Excellence in Marketing and Communications award. The citation pointed specifically to her expansion of marketing and advertising at MIAX, including the Sapphire launch and the MIAX Futures rebrand. The honor also formed a neat bracket around her career. In 2016, while at Convergex, she had received the publication's Excellence in Marketing award. Two awards eight years apart do not tell the whole story, but they show that the work traveled: from an agency brokerage and trading technology context to the broader canvas of an exchange group.
The in-house advantage
In April 2026, the next chapter appeared in airports, financial hubs and industry media. MIAX launched “Excellence in Every Exchange,” a nationwide advertising campaign following the company's 2025 initial public offering. The creative used bold three-dimensional forms to suggest motion and the speed of proprietary trading technology. Its colors mapped to the company's options, futures, equities and international businesses. The headline connected them through a standard of service and execution rather than a technical feature shared in exactly the same way.
One detail makes the campaign especially revealing: Annequin's team developed it in-house. In a technical company, proximity is a creative resource. An internal team can sit close to product, operations, technology, sales and leadership. It can hear which phrases carry meaning inside the business and which ones merely sound polished. It can also see how a claim about speed needs to sit beside claims about reliability, customer service and regulated markets. The work is less about finding one magic slogan than building a system in which the parts support one another.
“Our new campaign sets the stage for the next era of our brand's identity.”Kelli Annequin, 2026
Annequin described the campaign as the next era of MIAX's brand identity and tied it to the “highest standard of quality and professionalism in every interaction.” The word interaction carries weight for an exchange. An interaction can be a message sent through a trading system, a conversation with a member firm, a regulatory touchpoint or an experience with market data. The phrase takes a technical organization and gives it a human unit of measure. Every exchange is both a venue and an encounter.
Clarity as operating work
There is a temptation to treat financial marketing as a layer applied after the important decisions have been made. Annequin's path suggests a different model. When the company is entering markets, launching venues and combining identities, language is part of the operating work. Names set expectations. Product descriptions help customers locate themselves. Visual systems show which businesses belong together. Campaigns tell employees as well as outsiders what the organization believes its next chapter is about.
That work requires restraint. Market infrastructure serves readers who are alert to exaggeration and trained to ask how a system actually works. Credibility accumulates through the match between message and experience. The practical craft is to decide which details belong in the first sentence, which can wait for the product page and which should remain in the rule book. Annequin's cross-market career offers an advantage here. She has occupied organizations that create products, provide execution, advise clients and operate venues. Each one teaches a different definition of relevance.
Her work also sits inside a network larger than one employer. Annequin serves on the Security Traders Association of New York's Women in Finance committee. Her 2024 award remarks emphasized the value of recognizing women in the industry and credited a management culture that provides opportunity. It was a short statement, but it placed marketing achievement within an institutional context. Brands are built by what a company says, what it makes possible and who gets room to do the work.
The line from the Philadelphia Stock Exchange to MIAX is not a story of leaving complexity behind. It is a story of learning to work with complexity at larger scale. The instruments changed. The organizations changed. The public vocabulary of finance changed with them. Annequin kept returning to the same useful question: what does this institution need people to understand now?
For MIAX in 2026, the answer is a multi-asset exchange company entering a more public phase of its life, one with an identity intended to travel across venues and cities. For Annequin, it is another translation problem, which is another way of saying it is a marketing problem worth solving. Behind each concise message is the full market: the technology, the rules, the people and the split-second exchanges that make the words true.
