Black Friday 2026: A Uniquely High-Stakes Quarter

For most retailers, Black Friday and the wider Q4 period represent the single biggest revenue window of the year. That’s true every year.

What’s different this year is how much genuine volatility is stacking up against that narrow window, and how much of it demands a different response from PPC accounts specifically, not just from the business as a whole.

ChatGPT Ads: The Race for Profitability

ChatGPT now has 900 million weekly active users processing 2.5 billion prompts a day, and has reached roughly 17% of all global digital queries worldwide, according to First Page Sage’s Q2 2026 estimate, corroborated by two independent analyses in March 2026. That’s the first time in two decades that any platform has cracked Google’s near-monopoly with double-digit share. Some marketing analysts suggest organisations are earmarking 10-15% of total marketing budget for testing emerging channels generally, of which ChatGPT Ads is a leading candidate. For a platform barely six months old in the UK, that’s an unprecedented pace of adoption on both sides of the equation.

The platform is still visibly being built in public. In the past few weeks alone, OpenAI has rolled out conversion-optimised bidding for product feed campaigns in beta, added a direct Triple Whale integration for cross-channel measurement, and started testing a multi-product carousel format. Genuinely useful additions, but a reminder that the tooling is still shifting under advertisers’ feet heading into the busiest sale period of the year.

Nik Armenis, who tests ChatGPT Ads for eCommerce brands specifically, reports CPCs running high relative to Google and Meta, thin reporting, and very little room to optimise once ads are live. That pushes the real work upstream, into setup: segmenting products properly and building separate ad groups by category and customer need rather than lumping a catalogue together.

You can’t launch ChatGPT Ads for Black Friday itself and expect it to be profitable immediately. Given how limited in-flight optimisation currently is, advertisers need to get in early, work through setup and targeting properly, and arrive at Black Friday already at a reasonable level of profitability. Advertisers who launch purely for the sale period will be starting from behind competitors who’ve already done that work, and are likely to be operating at a loss during the exact window they can least afford to.

The Fight for Margin

Retailers are heading into Black Friday with less room to move on price than usual, and consumers are heading in wanting bigger discounts than ever, a genuine tension this year rather than the usual routine.

Inflation, rising shipping costs, and continued competition from low-cost platforms are all squeezing margins at the same time as squeezed household budgets are pushing consumers to expect more off.

Shipping costs specifically have also been pushed up by the crisis in the Strait of Hormuz, which has added up to two weeks of transit time as ships reroute away from the affected region, and that’s fed into higher input costs across the board.

Expect to see less of the blanket “30% off everything” this year, and more tiered offers advertised as “up to 30% off,” with retailers protecting margin more carefully than usual by concentrating discounts on specific products rather than applying them storewide.

For PPC, that means bidding strategies built around an even, blanket-discount assumption won’t match how retailers are actually promoting or how consumers are actually shopping. Build campaigns around which specific products carry real margin to discount, and be ready to shift budget toward the products where retailer and consumer interests actually meet.

Starting in October

A growing share of Black Friday activity is starting in late October rather than late November. Retailers including Currys and John Lewis began discounting on 30 October last year, and industry data shows most retail executives now see these earlier promotions as pulling the whole season forward.

For PPC, the practical implication is budget phasing. Accounts planned around a single late-November peak will be caught flat-footed by competitors already live weeks earlier. There’s a real first-mover incentive too: advertisers who go live before their competitors can capture early-shopping demand before the market gets crowded, which argues for weighting some budget toward late October rather than holding it all back for the traditional peak.

Budget on Autopilot = Revenue Left on the Table

Most advertisers are running Black Friday through PMax asset groups without adjusting bids for where margin is strongest, where stock is healthy, or where stock has become fragmented. Discounts shift conversion rates significantly once a sale goes live, but PMax’s learning period isn’t fast enough to pick up on that shift while it’s happening, so bidding lags well behind the real conversion behaviour it should be reacting to.

This matters even more in 2026, for two reasons:

First, PMax typically needs around two weeks to learn a new signal. A two-week learning curve doesn’t fit inside a two-week peak. By the time it’s learned what’s actually selling, the best window to capitalise on it may already be over, and by the time it’s learned what isn’t working, real budget has already gone toward finding that out.

Second, this is exactly the year stock is most likely to be fragmented or delayed, given the shipping disruption above. An automated system with no visibility into which SKUs are actually available is working blind at the worst possible time, spending on products that look good on paper but can’t be fulfilled, while under-spending on ones that are fully stocked and ready to convert.

I’ve seen this go wrong before. At a basic level, the fix is straightforward: get live stock data properly integrated into your account, and separate your campaigns so you can push specific products harder through their own dedicated asset groups, rather than leaving everything blended together and hoping the algorithm sorts it out.

If you want to go further, there’s a more advanced version of this. I’ve built a rule that scores each product on margin, discount depth, search demand, on-site sales performance, and stock coverage, then uses that score to decide how aggressively to push it, rather than relying on gut feel or a flat rule like “these ten products get more budget.” I’ve put together a free calculator showing how this works product by product, if you want to see the logic before building something similar into your own feed. (Disclosure: this is my own resource, hosted on my own website.)

Left on autopilot, that budget doesn’t disappear, it just goes to the wrong products.

Conclusion

None of these four pressures is unique to 2026 on its own. The difficulty is dealing with all four at once, in the few weeks where getting PPC wrong is most expensive.

It’s a lot to manage, and it’s genuinely messy.

Advertisers need to get on top of this now, not in the final weeks before Black Friday. The accounts that perform best won’t be the ones with the most automation. They’ll be the ones where someone is actively watching margin, stock, promotions, and performance, and willing to move budget when the numbers change.
