Sep 1
Opticon New York
New York
vendoropenecommerce
One day, Optimizely's own show. Worth it if experimentation is your problem this year.
September 2026
Sep 9–10
K:BOS
Boston
vendoropenecommerce
Klaviyo's own customer conference. Useful if you run on Klaviyo, thin if you do not.
Sep 14–16
Beanstalk
Brooklyn
boutiqueinvite onlyecommerce
Invite only, DTC founders and operators, built almost entirely around scheduled meetings. Exactly the kind of closed room nobody else lists.
Sep 14–17
Fast Company Innovation Festival
New York
majoropenbrand and creative
Broad innovation programming rather than a marketing conference. Good for the speaker list, less good for peers in your exact job.
Sep 15–17
Brandweek
Atlanta
majoropenbrand and creative
Adweek's own conference, and a different company from Advertising Week. Brand side rather than agency side.
Sep 15–17
Dreamforce
San Francisco
megaopenAI and tech
Enormous and vendor run. On here because a lot of martech budget gets decided in that week, not because it is a marketing event.
Sep 15–17
Forbes CMO Summit
Aspen
boutiqueapplygeneral
Private event, and you apply rather than buy a ticket. Chatham House Rule this year, which tells you what the room is for.
Sep 16–18
UNBOUND
Boston
megaopengeneral
This is INBOUND renamed. Sold out for 2026 as of late August, so the 2027 list is the realistic move.
Sep 22–24
Groceryshop
Las Vegas
majoropengrocery and CPG
The grocery and CPG side of the Shoptalk machine. Go for the retailer meetings, not the keynotes.
Sep 23–24
DMEXCO
Cologne
megaopenmedia and ad tech
The European digital marketing trade show. Two dense days, and the halls are the point.
Sep 28–29
Forrester B2B Forum EMEA
London
majoropengeneral
Analyst led and B2B only. The North America edition is in spring, so this is the one left in 2026.
Sep 29–Oct 1
Shoptalk Fall
Nashville
majoropenretail and commerce
Smaller than the Vegas edition, which is the reason to pick it. Easier to get thirty minutes with someone who matters.
October 2026
Oct 5–8
Advertising Week New York
New York
megaopenmedia and ad tech
The whole week is the event, spread across the city. ADWEEK House runs the same days as a separate thing by a different company, so check which one your invite is for.
Oct 5–7
Content Marketing World
Denver
majoropenbrand and creative
Conference on the fifth and sixth, workshops on the seventh. Practitioner heavy.
Oct 8
The Direct 60 Forum
New York
boutiqueinvite onlyecommerce
One day, closed list, run by the same people as The Lead Summit. Built around the attendee list rather than the stage.
Oct 13–15
MAICON
Cleveland
majoropenAI and tech
The AI in marketing conference that existed before every conference became an AI conference.
Oct 13
Oct 14
Festival of Marketing
London
majoropengeneral
One day in London, brand side, run by Marketing Week. Cheap in time relative to what it covers.
Oct 18–21
Money20/20 USA
Las Vegas
megaopeninvestor
Fintech rather than marketing. Here because payments and commerce keep turning into marketing problems.
Oct 20–23
ANA Masters of Marketing
Orlando
megaapplygeneral
If a US CMO goes to one thing in the autumn it is usually this. Members first, and ANA does not publish a venue on its calendar.
November 2026
Nov 2–4
MarketingProfs B2B Forum
Boston
majoropengeneral
Two conference days plus a workshop day. Smaller and more practical than the big B2B events.
Nov 3–5
Advertising Week LATAM
Mexico City
majoropenmedia and ad tech
The Latin America edition. Worth it if you have regional operations, skippable if you do not.
Nov 9–12
Web Summit
Lisbon
megaopenAI and tech
General tech at enormous scale. Brand marketers do go, but you will spend the week walking.
Nov 10–12
Adobe MAX
Miami Beach
majoropenbrand and creative
Creative tooling rather than marketing strategy. Adobe's own pages disagree on the year label, so check the date before booking.
Nov 12
ADWEEK House: Commerce Summit
Los Angeles
boutiqueapplyecommerce
One day, marketers and retailers and platforms in the same room. Small enough to be useful.
December 2026
Dec 1
CMO Summit London
London
boutiqueinvite onlygeneral
One day, invitation only, free to qualified attendees. The only senior marketing gathering anywhere on the calendar in December. Sponsor underwritten, so expect some of the room to be vendor conversations.
Dec 13–16
MediaPost Performance Marketing Insider Summit
Deer Valley
boutiqueapplymedia and ad tech
Four days at a ski resort in December with a small invited group. The format is the point.
January 2027
Jan 6–9
CES
Las Vegas
megaopenAI and tech
Not a marketing conference, but a large share of the year's media and agency conversations start here anyway.
Jan 10–12
NRF Retail's Big Show
New York
megaopenretail and commerce
The retail industry's January reset. Not a marketing conference, but every retail CMO is in the building.
February 2027
Feb 1–3
IAB Annual Leadership Meeting
San Antonio
majoropenmedia and ad tech
Where the digital advertising industry frames its measurement and policy fights for the year. Complimentary passes are offered to qualified brand marketers, so the cost of entry is travel. Media heavy rather than full funnel.
Feb 2–4
Shoptalk Luxe
Abu Dhabi
boutiqueopenretail and commerce
Luxury retail only, and a long flight. Narrow by design, which is either the whole value or the reason to skip it.
Feb 22–24
B2B Marketing Exchange
Carlsbad
majoropengeneral
The largest dedicated B2B marketing event in the US. The leadership track is real but a lot of the agenda is practitioner demand gen and ABM craft. Moved from Scottsdale, where it ran for years.
March 2027
Mar 1–4
MWC Barcelona
Barcelona
megaopenAI and tech
Not a marketing conference, and listed here with that said plainly. Enormous, and the brand and advertising presence keeps growing, but three days here is only worth it with a telco, device or connected experience stake.
Mar 10
CMO Summit New York
New York
boutiqueinvite onlygeneral
One of a city by city series CMO Alliance runs. Single day, so the cost is a day rather than a week.
Mar 15–21
SXSW Conference and Festivals
Austin
megaopenbrand and creative
Enormous, and hard to justify without a specific reason to be there. Dates here are the Conference and Festivals block, not the full run including SXSW EDU, which starts March 13.
Mar 22–25
Adobe Summit
Las Vegas
megaopenAI and tech
A vendor conference that operates at industry scale. Distinct from Adobe MAX, which is for creative practitioners; this one is marketing and customer experience leadership. The hero dates cover a March 22 preconference, with the main programme March 23 to 25.
Mar 22–24
Shoptalk Spring
Las Vegas
megaopenretail and commerce
The big one. If your team goes to exactly one retail event a year, it is usually this.
April 2027
Apr 5–7
POSSIBLE
Miami Beach
majoropenmedia and ad tech
Organizer has this under save-the-date wording rather than a published programme, so treat April as provisional until they firm it up.
Apr 20–23
Global Marketer Week
London
majoropengeneral
The global advertiser trade body's own week, and by the organizer's count 90 percent client side. The agenda is the governance conversation, media transparency and measurement standards, rather than tactics. If you pick three a year this one defends itself.
May 2027
May 3–5
Forrester B2B Summit North America
Phoenix
majoropengeneral
The flagship analyst event for B2B go to market, and much larger than the EMEA forum also on this calendar. You are pressure testing strategy against research rather than sitting through vendor pitches.
May 3–5
OMR Festival
Hamburg
megaopengeneral
The largest digital marketing event in Europe by a distance. The conference stages carry real leadership programming, but it is a loud sprawling festival and part of the language mix is German. Matters if the brand has any DACH exposure.
May 17–19
ANA Brand Masters
San Diego
majoropenbrand and creative
The ANA's brand building conference. Client side members attend at no cost, which keeps the room brand heavy rather than agency heavy. More focused on brand strategy and case work than Masters of Marketing.
May 19–20
The Lead Summit
New York
boutiqueapplyretail and commerce
Fashion and consumer retail. The curated attendee list is the product being sold.
May 24–26
ANA Masters of B2B
Chicago
majoropengeneral
The more senior of the two B2B options in this window. If you are choosing one, this is the leadership room and B2B Marketing Exchange is the practitioner one.
May 24–29
SXSW London
London
megaopenbrand and creative
A separate event from Austin, with its own organizer and a European audience. Worth the time for culture and brand positioning rather than marketing operations. Collides with ANA Masters of B2B and sits next to the Gartner London symposium.
May 26–27
Gartner Marketing Symposium/Xpo London
London
majoropengeneral
The EMEA analyst event with a pure marketing agenda. Two days, research led, and the peer group is other sitting CMOs rather than their teams.
May 27
CMO Summit Amsterdam
Amsterdam
boutiqueinvite onlygeneral
One day, invitation only, and the only Benelux entry on this calendar. Same format and same caveat as the London and New York editions.
June 2027
Jun 1–3
Shoptalk Europe
Barcelona
majoropenretail and commerce
Worth the trip if you have European operations. Largely a repeat of Vegas if you do not.
Jun 7–9
ANA AI and Technology for Marketers
Phoenix
majoropenAI and tech
Where a lot of 2027 marketing technology budget gets rationalised. Worth rechecking nearer the time: the organizer's own URL slug reads October while the page body and their conference index both say June.
Jun 7–9
Gartner Marketing Symposium/Xpo Denver
Denver
majoropengeneral
Gartner's flagship North American marketing event, and the most defensible three days on this list for a US CMO. Research led sessions and one to one analyst time, with a peer group of actual marketing chiefs.
Jun 8–9
CommerceNext Growth Show
New York
majoropenecommerce
Practitioner heavy and light on vendor theater. Venue changed to North Javits for 2027, so old listings elsewhere are wrong on both date and place.
Jun 21–25
Cannes Lions International Festival of Creativity
Cannes
megaopenbrand and creative
An awards festival on paper and the industry's dealmaking week in practice. The expensive part is not the badge.
July 2027
Jul 18–20
MMA CMO + CEO Summit
Santa Barbara
boutiqueinvite onlygeneral
Invitation only, CMOs in the room with CEOs. MMA now goes by Marketing + Media Alliance, not Mobile Marketing Association.
October 2027
Oct 12–14
POSSIBLE Europe
Lisbon
majoropenmedia and ad tech
The European POSSIBLE. Same organizer and same meeting-led format as Miami Beach.
