2026 Holiday Marketing: Rising Ad Budgets Meet AI-Powered Discovery
The 2026 holiday season is the first where AI agents are meaningfully changing how shoppers discover products. Three data points published in the last two weeks tell the story. Yahoo DSP's 2026 Holiday Shopping Study, reported by Chain Store Age on September 23, found that 55% of retail marketers are increasing their holiday ad budgets this year, up from 44% last year. Circana published its holiday media playbook on September 22, identifying AI-assisted discovery as one of five trends shaping the season. And eMarketer reported the same week that AI shopping is fundamentally changing the holiday path to purchase.
Budgets are going up. Discovery is changing. The businesses that treat these as separate trends will overspend on a fading playbook. The ones that connect them will allocate smarter.
The Budget Picture
Yahoo DSP's 2026 Holiday Shopping Study, cited by Chain Store Age on September 23, reveals a significant year-over-year shift in marketer confidence.
| Metric | 2025 Holiday | 2026 Holiday | Change |
|---|---|---|---|
| Marketers increasing budgets | 44% | 55% | +11pp |
| Agencies increasing budgets | - | 57% | New high |
| Marketers expecting to launch by November | - | 77% | - |
| October as biggest launch month | - | 34% launch | - |
Of the agencies polled, 57% are planning increases, as are 54% of in-house marketers. Seventy-seven percent of advertisers expect to launch their holiday campaigns by November, with October as the biggest single month for campaign launches at 34%.
The budget increase is not surprising on its own. Holiday spending typically rises year over year. What makes 2026 different is where that money needs to go. The same marketers who are raising budgets are also navigating a discovery landscape that no longer runs exclusively through Google Search and Meta ads.
How AI Is Changing Holiday Discovery
Circana's holiday media report, published September 22, identifies five trends shaping Holiday 2026. Three of them directly involve AI or shifts in how consumers find products:
AI-assisted discovery. Consumers are increasingly using AI tools to research products, compare options, and receive recommendations. This includes ChatGPT product searches, Google AI Overviews with shopping links, and emerging agent-mediated shopping experiences where an AI agent acts on behalf of the consumer.
Earlier shopping. The holiday window is expanding. Consumers are starting research and purchases earlier, partly because AI tools make comparison shopping faster and more accessible year-round.
Social commerce. Social platforms continue to grow as discovery and purchase channels, with AI-powered recommendation engines making it easier for consumers to find and buy without leaving a platform.
Circana identifies two additional trends in its full report, which also covers macro pricing dynamics and cross-channel media allocation. The report is available on Circana's website.
eMarketer's September 22 analysis reinforces the same picture: AI shopping is not a future trend. It is changing this year's holiday path to purchase. The analysis points to Google's agentic commerce updates, rolled out in September, which include structured conversational attributes for merchants and native AI checkout for eligible Shopify merchants.
Google's Agentic Commerce Push for Retailers
Google has been building agentic commerce infrastructure ahead of the holiday season. The updates, announced progressively through September 2026, create new surfaces where products can be discovered and purchased through AI-mediated interactions.
Key developments:
- Structured conversational attributes. Google introduced new structured data types for merchants that make product information available to AI agents in a machine-readable format. This enables AI assistants to query product details, availability, and pricing in real time.
- Native AI checkout for Shopify. Search Engine Land reported on September 18 that Google opened native AI checkout to eligible Shopify merchants, allowing consumers to complete purchases within Google AI shopping experiences without leaving the AI interface.
- Shorter commerce timelines. MediaPost reported on September 18 that Google's agentic updates are compressing the time between discovery and purchase, meaning businesses need to be prepared for faster decision cycles.
- Universal Commerce Protocol expansion. Chain Store Age reported on September 22 that Google expanded its open-source agentic commerce protocol, giving retailers new AI tools for managing agent-mediated transactions.
For SMBs, the practical implication is that product discoverability now depends on more than keywords and ad bids. It depends on structured data, conversational readiness, and whether your product information is accessible to AI agents that are increasingly mediating the buyer journey.
The Practical Playbook for SMBs
If you are a small or mid-size business preparing for Holiday 2026, here is how to connect the budget trend with the discovery shift.
Step 1: Audit Structured Data Before Spending More
Before increasing ad budgets, make sure your product data is visible to AI discovery surfaces. This means product schema markup, availability signals, and pricing information in structured formats that AI agents can read. If your product pages load beautifully in a browser but are invisible to AI crawlers, your increased ad spend will underperform. A structured data audit takes a few hours and can be done with free tools from Google Search Console.
Step 2: Reallocate Rather Than Just Increase
The 55% of marketers increasing budgets should not be adding that money exclusively to existing channels. Consider reallocating a portion of the increase toward AI discovery readiness.
A practical split for an SMB with a modest holiday budget:
| Channel | Allocation | Rationale |
|---|---|---|
| Google/Meta ads | 55-65% | Core performance, retargeting |
| AI discovery prep | 10-15% | Structured data, content for AI citations |
| Social commerce | 10-15% | Platforms where AI recs drive discovery |
| ChatGPT Ads (if eligible) | 5-10% | Early test, conversational format |
| Reserve | 5-10% | Optimize based on early results |
The specific allocations will vary by business, but the principle holds: do not let increased budgets entrench you in a single discovery model that is being disrupted.
Step 3: Prepare for Faster Decision Cycles
MediaPost's reporting on September 18 noted that Google's agentic updates are compressing commerce timelines. When AI agents can compare products, check availability, and initiate checkout in seconds, the window between discovery and purchase shrinks dramatically. For SMBs, this means product pages need to load fast, inventory must be current, and pricing must be consistent across all channels. A mismatch between your website price and the price an AI agent surfaces will kill the sale.
Step 4: Test Conversational Readiness
Even if you are not running ChatGPT Ads yet, prepare for a world where conversational AI mediates the buyer journey. Audit your FAQ, product descriptions, and customer service knowledge base. Are they clear enough that an AI agent could read them and accurately represent your business? If not, invest in improving them before the holiday rush.
Step 5: Start Earlier
Circana and Yahoo DSP both note that holiday shopping is starting earlier. With 34% of marketers launching in October and the AI discovery cycle beginning well before that, SMBs should have product data, structured markup, and ad creative ready by early October at the latest. Waiting until November means missing the early research phase where AI agents are already surfacing product recommendations.
What This Means for Local Businesses
Local businesses face a specific version of this shift. Google AI Overviews now appear on a significant share of local-intent queries. An AI agent looking for a gift shop in Montreal does not read search ads first. It reads structured data, reviews, and local business information. If your Google Business Profile is incomplete or your local schema markup is missing, you will not appear in AI-mediated local discovery, regardless of how much you spend on ads.
For local businesses, the highest-ROI holiday investment may not be additional ad spend. It may be completing and optimizing your Google Business Profile, ensuring local schema is correct on your website, and building review velocity in October before the holiday research phase peaks.
The Bottom Line
The 2026 holiday season is a turning point. It is the first comfortable overlap of rising ad budgets, AI-powered discovery, and agent-mediated commerce. Businesses that treat these as separate trends will spend more for the same or diminishing returns. Businesses that integrate them will find new efficiencies and new paths to their customers.
