Conferences and trade shows Where should you be in 2027?

Find your industry’s 2027 conferences and trade shows: one list per industry, with the IT channel first. Every list gives the same fields for every show, and every list is checked again each October.

Which industry are you in?

Pick your list. Each one covers the 2027 shows in that industry, with dates, size and cost bands side by side.

• Cybersecurity and IT channel conferences. For vendors who sell through MSPs (managed service providers, the companies that run IT for other businesses) and resellers, or straight to security teams. Channel shows and security shows on one list.
• Marketing conferences. For B2B marketing and events teams deciding which conferences earn a place on the calendar.
• Construction trade shows. For exhibitors weighing the big floors against the regional shows.
• HR conferences. For companies that sell to HR teams, and for HR teams choosing where to go.
• Education conferences. For the teams that exhibit at education and edtech shows as much as the teams that attend.
• Tech conferences. The broad tech list: developer, SaaS, enterprise IT and consumer tech shows. Channel and security shows sit on the first list.
• Healthcare trade shows. Healthcare and medical shows, for exhibitors and sponsors as well as attendees.
• Real estate conferences. For companies that sell into real estate and want to know which shows are worth a booth.
• Sales conferences. For sponsors, and what a sponsor gets from each show.
• Trade shows by industry. Industry not listed here? A repeatable way to find the right shows in any B2B industry, retail and packaging included.
• Manufacturing trade shows. For exhibitors choosing between the major national floors and the regional shows.
• Automotive trade shows. For suppliers and service providers deciding which automotive shows put them in front of buyers.

How every list works

Every show on every list gets the same fields, so two shows can be compared line by line:

• Dates of the next edition. When the host has not announced them, the entry says TBA and gives the month the show usually runs.
• City, and the venue where the host names one.
• Host, the organization that runs the show, named and linked.
• Who attends, in one line: roles and company types.
• Size, as a band.
• Booth, sponsorship and ticket costs, as bands.
• Best for: new customers, partners, recruiting or learning, with the main one first and the reason in one sentence.

Bands, not exact prices, because prospectus prices change and an exact figure is wrong within a year. An exact figure can still appear in a show’s own entry, with its source and year beside it. The scales are the same on every list:

Field	Bands
Size	under 500 / 500 to 2,000 / 2,000 to 5,000 / 5,000 to 20,000 / 20,000+
Booth and sponsorship	under $5,000 / $5,000 to $15,000 / $15,000 to $50,000 / $50,000 to $150,000 / $150,000+
Ticket	free / under $500 / $500 to $1,500 / $1,500 to $3,000 / $3,000+

“On request” means the host sells booths or sponsorships but has not published the price on the pages checked, so you ask for its exhibitor prospectus. “Not published” means the host has not released that figure on the pages checked, and the band stays blank rather than guessed. Either one tells you what to ask before you sign.

Each figure carries its source and the year it describes. Each entry is re-verified every October (dates, hosts and prices), and the Updated date on the list changes then.

Where to start: the list for the industry your buyers work in. What to skip, at first: the largest shows below. On floors that size, a first booth is easy to miss.

Run one of these shows? Every entry names its host, and Events Authority offers exhibitor training for event hosts for hosts who want exhibitors who come back.

Deciding which shows earn a booth is its own job. The method is in how to choose the trade shows worth your budget.

The largest trade shows in the US

Each figure below is the host’s own, from the host’s own site, tied to the edition it describes. A show whose host did not tie a figure to an edition is left out, which is why this is four shows and not a ranking. Many “largest trade shows” lists print a number with no year and no source; each figure here links to the page it came from.

Listed by next edition date.

Show (industry)	Host	Next edition	Where	Host’s figure
Natural Products Expo West (natural and health products)	New Hope Network	March 2 to 5, 2027	Anaheim Convention Center, Anaheim, CA	66,000+ attendees, 2026
HIMSS Global Health Conference & Exhibition (healthcare)	HIMSS (Informa Markets)	April 5 to 8, 2027	McCormick Place, Chicago, IL	“over 24,000+ healthcare pioneers converged”, HIMSS26
IMTS, the International Manufacturing Technology Show (manufacturing technology)	AMT, The Association For Manufacturing Technology	September 14 to 19, 2028	Not stated on the host page checked	Over 90,000 attendees, 2026
CONEXPO-CON/AGG (construction and heavy equipment)	Association of Equipment Manufacturers (AEM), with co-owners NRMCA and NSSGA	March 13 to 17, 2029	Las Vegas Convention Center, Las Vegas, NV	140,000+ attendees, 2026

The industries are all different, and so is what “largest” means. Some lists rank shows by attendance, some by exhibitors, some by net square feet of floor, so the same show can place differently from one list to the next.

Two of these are not on a 2027 calendar at all. IMTS runs every two years, next in September 2028, and CONEXPO-CON/AGG every three years, next in March 2029. HIMSS and Expo West both have 2027 dates.

SEMA Show, CES, NAB Show, NRF’s Big Show and RSA Conference were checked too, and left out because the host pages checked did not tie a figure to a specific edition.

For a first booth, the industry lists above are the better place to look. They carry the smaller shows as well, with booth and ticket bands beside each one.

Common questions

Where do you start if you only know your industry? Start with who you need to meet. Open the list for the industry your buyers work in, which may not be your own. If that industry has no list of its own, the trade shows by industry page, tenth in the index above, gives a repeatable way to find the right shows in any B2B industry.

What do the bands, “on request” and “not published” mean? Bands are ranges for size, booth, sponsorship and ticket costs, used because prospectus prices change within a year. “On request” means the host sells booths or sponsorships but has not published the price on the pages checked, so ask for the exhibitor prospectus. “Not published” means the host has not released that figure on the pages checked.

How often are the conference lists updated? Every list is re-verified each October: dates, hosts and prices. When a news item on this site covers new dates or a venue move, the show’s entry is updated the same week. The Updated date at the top of each list shows when it was last checked.

Where do the largest trade show figures come from? From each host’s own site, checked in late September 2026. Each figure is the host’s, tied to the edition it describes, and linked to the page it came from. Shows whose hosts did not tie a figure to an edition are left out rather than estimated.

How is this page different from the trade shows by industry page? This page is the index: every industry list, plus the largest US shows. The trade shows by industry page is a method for finding the right shows in any B2B industry, including the ones without a list here yet.

How does an event host get exhibitors ready? Events Authority’s exhibitor training for event hosts, linked in “How every list works” above, is built for that: preparing exhibitors so they get enough from your show to come back.
