Fifteen Years of IMEX America: Las Vegas Lights the Sign Pink and Launches 'The Vegas Effect'

LAS VEGAS

Fifteen years in, the biggest trade show in the American meetings business got the full Las Vegas treatment this week — and the city used the occasion to launch a brand-new pitch to the people who decide where the world's conventions go. IMEX America, the largest U.S. trade show for the global meetings, events and incentive travel industry, wrapped its 2026 edition on Thursday, October 15, at the Mandalay Bay Convention Center, closing out a three-day run that began October 13 and marked a decade and a half since the show debuted in Las Vegas in 2011.

The Las Vegas Convention and Visitors Authority (LVCVA) coordinated the anniversary gestures, according to the announcement distributed via The News Market. The Welcome to Fabulous Las Vegas sign — the most photographed welcome mat in tourism — was lit pink for the occasion, and marquees up and down the Strip carried tribute messages honoring the show's 15 years in the city. It was a fitting backdrop: few partnerships in the convention business have been as durable, or as lucrative, as the one between IMEX and Las Vegas.

The LVCVA's own figures, cited in the anniversary announcement, put hard numbers on that durability. Over 15 years, IMEX America has drawn nearly 185,000 participants to Las Vegas and generated an estimated $360 million in economic impact. Those are show-specific numbers inside a much larger machine: the LVCVA says Las Vegas welcomed 6 million convention attendees in 2025, and that convention business generated $17.1 billion in overall economic output for the region. The city backs the pitch with roughly 15 million square feet of meeting and exhibit space — a supply of ballrooms, halls and breakout rooms that no competing destination in North America can match at a single address cluster.

The sign ceremony doubled as a roll call of the people who run that machine. According to the LVCVA account carried by The News Market, the gathering at the sign included LVCVA president and CEO Steve Hill, chief sales officer Vanessa Claspill, and Clark County Commissioner Jim Gibson, who chairs the LVCVA board, alongside IMEX founder and chairman Ray Bloom and IMEX CEO Carina Bauer. When the authority that markets a city and the executives who run its biggest trade show stand together under a pink-lit landmark, the message is aimed well beyond the photo: this relationship is a cornerstone, and both sides intend to keep it that way.

The bigger news for the industry, though, was what Las Vegas launched around the anniversary. The LVCVA used IMEX week to debut "The Vegas Effect," a new business brand platform and advertising campaign aimed squarely at meeting planners and business decision-makers — the people who choose where thousands of attendees will sleep, eat and spend. According to Vegas Means Business, the LVCVA's meetings-industry site, the campaign includes 30- and 60-second spots and will run across paid video, digital and social channels. The idea behind the name is the pitch every planner hears in this city: that an event held in Las Vegas draws differently — that attendance, energy and exhibitor interest get a lift simply from the destination on the badge.

Nobody at the LVCVA undersold what IMEX means to that argument. Rebecca DeLuca of the LVCVA, quoted by Vegas Means Business, called IMEX the authority's "Super Bowl on the convention side" — a comparison that, in a city that has actually hosted a Super Bowl, carries deliberate weight. The show floor at Mandalay Bay functions as the industry's annual marketplace, where destinations from every continent compete for the same planner budgets Las Vegas is courting with its new campaign. Hosting the marketplace itself, year after year, is the home-field advantage the Vegas Effect campaign is built to extend.

And the partnership now has a new shape on the calendar. As Prevue Meetings reported, IMEX America will move to September for its next two editions — September 28–30, 2027, and September 26–28, 2028 — remaining at Mandalay Bay, with a "Hello September" campaign marking the shift. The move pulls the show out of the crowded mid-October corridor — a stretch when Las Vegas is juggling everything from fall conventions to, as our readers know, the roadwork and build-up for the Formula 1 weekend (see our coverage of the Flamingo and Koval closure for the F1 bridge build) — and plants it in a late-September window the show can own.

For Las Vegas, the week amounted to a thesis statement. The leisure side of the Strip can take care of itself — tonight alone brings the opening of a major new magic production at MGM Grand, which we cover in our story on 'Now You See Me Live', on top of the week's other openings. The convention side is where the city's economic engine quietly runs, midweek and year-round, filling hotel rooms on Tuesdays and restaurants on Wednesday nights. Fifteen years of IMEX, $360 million in estimated impact and a fresh brand campaign later, Las Vegas is not just defending its title as the meetings capital — it is advertising the defense. Planners deciding on 2027 and beyond now have two new September dates, a pink sign photo, and a name for what the city claims happens to events that come here: the Vegas Effect.

IMEX America returns to Mandalay Bay on September 28–30, 2027. For more Las Vegas business and Strip coverage, browse the Previously newsroom or head back to the homepage.
