Now the events themselves.

At a glance: 13 events that matter

(13 events plus AWS's three-summit blitz counted as a single force.)

Force 1 — The AI Platform War (3 keynotes, 1 narrative)

Google I/O — May 19–20, Mountain View. Microsoft Build — June 2–3, San Francisco. WWDC — June 8–12, Cupertino.

Three AI keynotes. Three weeks. One buyer.

What changed from 2025: each company is now selling agentic AI tooling — autonomous agents that act on a user's behalf — not chat assistants. The CTO question is no longer "should we use AI?" It's "which platform's agent ecosystem do we standardize on?" That's a procurement question, not an experimentation budget.

Watch for:

• Google I/O — Gemini-on-Workspace agents, multi-modal continuity, and how aggressively Google ties Search to agent-driven shopping
• Microsoft Build — billed as a "no-fluff" event by Microsoft itself; expect Copilot extensibility, agent SDKs, and Azure agentic workflows targeting the enterprise stack Salesforce and ServiceNow already own
• WWDC — Apple's developer story is structurally different (privacy, on-device); the question is whether Apple Intelligence agents bridge consumer and enterprise, or stay consumer-only

If your company sells anything that touches AI workflow, this three-week stretch is non-optional. The platforms announced here are the platforms your prospects will benchmark you against for the rest of 2026.

Force 2 — Industrial AI hits the show floor

Automate 2026 — June 22–25, Chicago.

Hannover Messe in April was where the industrial-AI thesis got framed: predictive maintenance, computer-vision QA, autonomous mobile robots, agentic supply-chain optimization. Automate is where it gets stress-tested by North American manufacturers — and where vendors find out whether the pitch deck closes in Chicago the way it closed in Hannover.

What to track:

• Which of the Hannover-coined industrial-AI deployment patterns (see our Industrial AI in Manufacturing cluster) get demo time at Automate vs. quietly disappear
• How named industrial buyers (not vendors) talk about ROI — payback periods of <12 months are now table stakes
• The robotics-as-a-service pricing wars heating up: monthly subscription models are eating capex sales

Automate is the most under-covered show on this list relative to the dollars actually changing hands. If your team sells into manufacturing, this is the one that matters. (Hannover context: Hannover Messe 2026 Recap and Exhibitor's Guide.)

Force 3 — The defense cycle resets

EuroSatory 2026 — June 15–19, Paris.

EuroSatory runs every two years, which means everything announced in 2026 sets defense procurement priorities until 2028. There is no "next year" to wait for.

Three storylines to track:

• Drone autonomy — the gap between "remote-piloted" and "autonomous" closed faster than European procurement cycles can absorb. Watch how primes (Airbus, Leonardo, Thales) reframe their roadmaps.
• Defense-AI — battlefield AI moves from research demos to deployed systems. NATO procurement language is the leading indicator.
• Satellite + space-based ISR — commercial satellite operators (Maxar, Planet, ICEYE) increasingly bid on what used to be exclusive defense contracts.

EuroSatory's adjacency to civilian markets is underappreciated. Drone autonomy, satellite imagery, and edge-AI compute all spill into commercial industries within 18 months of the show.

Force 4 — Pro AV's hybrid-experience pivot

InfoComm 2026 — June 13–19, Las Vegas.

InfoComm is the largest pro-AV show in North America, and 2026 is the first year since 2020 where event-tech investments aren't being justified on safety/COVID grounds. The buyer changed. AV is no longer an IT expense — it's a productivity line item. That single shift rewrites the entire vendor pitch.

The people writing checks now ask "what's the productivity case?" — not "how do we keep meetings safe?" Vendors that can't articulate hybrid-event ROI in one sentence will lose share fast. Digital signage, AV-over-IP, hybrid-event tooling — all sold to the same buyer who used to live in IT and now reports up through ops or facilities.

Worth attending if you're in: corporate AV/IT, event production, digital signage, control rooms, broadcast, or higher-ed instructional tech.

Force 5 — Industry-specific AI goes mainstream

NRA Show — May 16–19, Chicago. Cannes Lions — June 22–26, France. BIO International — June 22–25, San Diego.

Three industries, same headline question: what does AI actually do for us? Three very different answers.

• NRA Show (foodservice) — AI in operations under margin pressure: labor scheduling, ordering kiosks, supply-chain forecasting, kitchen vision. Not "is AI cool?" — "does it land 200 bps of margin in a year of cost inflation?" Watch which brands name their AI vendors on stage. That's the procurement signal.
• Cannes Lions (advertising / creative) — first Cannes where AI-generated creative is a serious competitive category, not a curiosity. Watch the Innovation and Industry Craft Lions for the split between agencies with proprietary AI workflows and agencies still treating AI as "use Midjourney faster." Brand-safety, IP, and authorial credit are now CMO conversations — not legal memos.
• BIO International (biotech / pharma) — AI in drug discovery moves from R&D demos to clinical-pipeline reality. Named molecules from AI-designed pipelines entering Phase 1. Big-pharma partnership announcements with AI-native biotechs. FDA stance on AI-driven submissions.

In 2026, every vertical is past the "explainer talk" stage on AI. The question is execution proof — and that's exactly what these three shows put on stage.

Force 6 — Cloud saturation: AWS's June blitz

AWS Summit Los Angeles — June 10. AWS Summit New York — June 17. AWS Summit Washington, D.C. — June 30–July 1.

This isn't three events. It's one message, repeated to three different enterprise buyers:

• LA — media/entertainment, gaming, ad-tech (West Coast enterprise)
• NYC — financial services, retail, pharma (East Coast enterprise)
• DC — public sector, defense, federal/state agencies (350+ sessions, two days)

The throughline: agentic AI workflows, Bedrock-native tooling, and AI-for-public-sector. AWS is repositioning, and they're betting the same pitch lands differently in three rooms.

For partners, ISVs, and customers: pick the summit closest to your buyer. Skip the other two. You don't need three.

Force 7 — The non-US tech corridor

Computex 2026 — June 2–5, Taipei. VivaTech 2026 — June 17–20, Paris.

Tech happens outside Silicon Valley. These two shows reframe what "the tech industry" actually looks like in 2026.

• Computex is the hardware supply chain made visible. NVIDIA, AMD, Intel, plus the Taiwanese ODMs/OEMs that build virtually every server, AI-PC, and data-center rack on the planet. The roadmap unveiled at Computex is what enterprise IT will be deploying 18 months later. The AI-PC category lives or dies on what's demo'd here.
• VivaTech is Europe's bet on building a sovereign tech ecosystem — 180K attendees, French government backing, a flag for "European AI" that isn't a thin wrapper on American models. Whether you take that seriously or not, the capital flows are real, and any company selling into European enterprise should know who's on the VivaTech keynote stage.

Note the schedule: Microsoft Build (San Francisco) and Computex (Taipei) overlap on June 2–3. That tension — U.S. platform announcements vs. Asian hardware reality — is the Force 7 thesis in a single calendar collision.

Skip or deprioritize (unless you're in the niche)

Authority means saying what not to do. Here's what to deprioritize across this 60-day window:

• Multiple AWS regional summits — one is enough. Pick the one closest to your buyer and skip the others. Attending all three is a budget leak, not a strategy. If you need to attend all three to justify your pipeline, the problem isn't geography — it's positioning.
• Me-too AI expos — any event where the agenda doesn't include named industrial buyers, proprietary research, or original data is filler. If the speaker list is "AI thought leaders" without titles like "VP of AI at [Fortune 500]," save the flight.
• Regional clones of global flagship shows — when InfoComm, Automate, or BIO is the same month, regional AV/automation/biotech expos rarely add signal. Wait for the global ones.
• Adobe Summit recaps — March is over; the 2026 takeaways have been written. Reading another recap in May isn't strategy work.

This isn't about being cynical — it's about your team's calendar being a finite resource that compounds badly when you fill it with low-signal events.

FAQ

Which May–June 2026 show has the highest exhibitor ROI? It depends entirely on your buyer. For exhibitors targeting industrial buyers, Automate consistently posts strong qualified-lead density; for biotech, BIO International's partnering meetings drive most of the deal flow; for advertising/creative, Cannes Lions converts at the brand-CMO level that no other show touches. The exhibitor question is rarely "which show is biggest" — it's "which show puts my buyer in the room?"

Should I attend if I'm not exhibiting? For the AI Platform War (I/O / Build / WWDC) — yes, even just for the keynote stream and the corridor conversations. For Automate, EuroSatory, and BIO — only if you're actively buying, partnering, or investing. For Cannes Lions — attend if your team makes brand creative decisions; the work shown sets the bar for the year.

What's genuinely new in 2026 vs. 2025? The agentic-AI shift from chat assistants to autonomous workflows is the biggest cross-industry change. EuroSatory's "on" year resets defense procurement. NRA, Cannes Lions, and BIO each cross the threshold from "AI is interesting" to "AI is in the procurement budget." Computex's AI-PC roadmap matures. VivaTech reaches 180K — Europe's tech corridor is no longer aspirational.

I can only pick one — what should it be? For most B2B teams: Automate (June 22–25). It's the most under-priced event relative to qualified-buyer density on this list, and the industrial-AI storyline running through it intersects almost every other vertical. For pure tech/dev teams: Microsoft Build. For creative/brand: Cannes Lions.

Plan smarter for May–June 2026

The 13 events above are where the second half of 2026 takes shape. If you're making budget decisions, do these three things:

1. Run the budget framework. Before committing, work through Trade Show ROI: How to Measure What Actually Matters — it'll tell you which of the 13 are worth the spend for your team.
2. Use the TradeShowBuzz /shows directory to dig deeper on any show in the table — exhibitor lists, agendas, location logistics.
3. Check back in late June for the May–June 2026 recap, the natural sister piece to this preview (and to the April 2026 Trade Shows Calendar).

The shows that shape your year are rarely the loudest. They're the ones where your buyer is in the room — and where the storylines you're already tracking move forward by a measurable step. That's the filter for May–June 2026.
