Monday Briefing: Meta Makes You Liable for Its AI

Good morning, it's James here. Meta rewrote the contract every advertiser signs, and the new version puts the risk from its AI tools on you. After publishers complained to European regulators, Meta pushed the start date back three weeks, to Nov. 20, six days before Thanksgiving. Also in this issue, Salesforce and Publicis are buying Braze and LiveRamp, and 43% of Americans say an AI has sent them to a store they'd never used.

The Lead: Meta Makes You Liable for Its AI

What happened. Meta's updated Commercial Terms add a section called "AI Features." Adweek reports that under it, advertisers "will be 'solely responsible' for whatever its AI features create or change, including features Meta switches on." The terms say those features "may make mistakes and may not always produce accurate, complete, or suitable results" (Adweek).

The edits are already showing up in live ads. Bookshop.org said an ad was "'enhanced' (or ruined, really) by Meta without our knowledge after an account update opted us in to their new ad features." Agency Exverus has pulled live ads to remove sitelinks, translations and AI images it never requested. "If every one of those isn't manually unchecked, the enhancements still apply," said Ryan Adams, a paid search and social specialist there (Adweek).

The same terms let Meta crawl websites "associated with" business accounts. Legal experts told Nieman Lab the wording gives Meta "an opening" to argue the terms override robots.txt blocks (Nieman Lab). German publishers' associations filed a complaint with the European Commission on Tuesday (MLex). On Friday, Meta moved the effective date from Oct. 30 to Nov. 20, saying the extra time lets it "explain to our partners and stakeholders what's changing and what's not" (MLex). Meta's terms page now shows the new date (Meta).

Why CMOs should care. If Meta's AI adds a wrong price or an off-brand image to your ad during Black Friday week, the contract makes that your problem. Asked whether advertisers are liable for features they never turned on, a Meta spokesperson didn't answer directly. The spokesperson said only that advertisers can switch off individual Advantage+ features in Ads Manager (Adweek).

The take. I think Meta has this the wrong way round. It keeps asking advertisers to hand more of each ad to its AI, and under these terms the advertiser carries the risk when that AI gets it wrong, even if Meta turned the feature on. Meta says it needs more time to explain the terms, and it hasn't said it will drop the AI Features section. David Dweck of Go Fish Digital, whose lawyers are reviewing the terms, called this "the tax of advertising on Meta" and said his agency won't tell clients to pull back in Q4. I expect most of you will make the same call, so spend the three weeks on checks. Have someone open every live Q4 ad and switch off each Advantage+ creative enhancement your team hasn't approved, and repeat that after every account update, since an update is how Bookshop got opted in. Have legal read the AI Features and crawling sections before Nov. 20. If an agency runs your Meta buying, ask who checks ads after launch and how often.

Money Moves: Salesforce Buys Braze, Publicis Gets LiveRamp

Salesforce agreed to buy Braze for about $5.66 billion, or $47.50 a share in cash. Braze has about 2,770 customers, including Canva, Instacart and Venmo, and the deal is expected to close in Salesforce's fiscal 2028 (Salesforce).

Publicis reached a proposed FTC consent order for its $2.2 billion LiveRamp purchase. For five years, LiveRamp must give everyone nondiscriminatory access, and firewalls must keep Publicis out of LiveRamp customer data. WPP is winding down its agencies' use of LiveRamp, and Omnicom sped up its plan to drop it (Marketing Dive).

Both were independent tools you could plug into any stack. Once these deals close, one belongs to a software suite and the other to an agency group, and I'd expect each owner to steer customers toward its own products. If either sits in your stack, ask for the product roadmap and your contract's change-of-control terms before your next renewal.

In Partnership With Kalshi

Big companies hedge their risks. Now your business can too.

For US farm, ranch and small business owners.

Airlines hedge fuel. Food companies hedge crops. For decades, protecting a business from outcomes it can't control took a broker, a trading desk and an order size most owners never had.

Kalshi opens hedging up to small businesses. Pick the outcome that would hurt you, like a fuel spike, a heat wave, a new tariff or a rate hike, and take a position on it, starting at a few dollars. If it happens, the payout offsets the hit. If it doesn't, the contract expires and the good month was the point.

A California goat herder and a Maryland tea company already do it, and CNBC, Reuters and The New York Times have covered businesses hedging on Kalshi.

Kalshi is a federally regulated exchange.

Consumer Signal: 43%

That's the share of Americans who have found or bought from a retailer they'd never used before because an AI recommended it. Among 18- to 34-year-olds, the figure is 68%. Overall, 67% plan to use AI for holiday shopping this year, and 53% would let AI buy a gift on its own, depending on the amount. The Harris Poll surveyed 2,017 US adults on Sept. 15-16 for Forter (PR Newswire). Forter sells fraud and payments tools to retailers, so it has a reason to make AI shopping sound urgent.

The survey is self-reported, and I'd still take it seriously. Ask your ecommerce lead how much traffic now comes from AI assistants, and whether those assistants quote your prices and stock correctly.

Omnicom says the IPG integration is "substantially completed" (Marketing Dive) Third-quarter organic growth was 7.2%, and Coca-Cola moved its North American media to Omnicom.
Can flipping the ad auction loosen Google's grip? (Digiday) Prebid wants Google's ad server to bid into Prebid instead of the other way around. The target is early 2027, and Google hasn't committed.
Billion Dollar Boy Group bets B2B is creator marketing's next big wave (Marketing Dive) BDB Group is buying Creator Authority, a LinkedIn-first agency, and cites LinkedIn data that 59% of B2B buyers pay attention to creator content there.
Anthropologie's holiday plan (Marketing Dive) CMO Barbra Sainsurin describes the holidays as "a world our customer can step into, rather than a single campaign she sees," built from in-house ads, creator series and a DoorDash test.
Butterfinger's Headless Horseman returns (System1) Last year's 15-second Halloween spot is back and scores 4.7 stars. System1 points out that Christmas has ads that return every year and Halloween mostly doesn't, which makes Butterfinger's rerun unusual.

One More Thing

Starting in early 2027, Google will require advertisers in the US and Canada to show they are "authorized by relevant regulators or recognized registries before running certain financial ads." In the US, it will check banks against the American Bankers Association's registry (Google). If you market a bank, card or fintech product, assign someone to handle the verification now. Google says it will notify advertisers when they need to complete it, and you don't want that notice landing during January planning.

See you next Monday.
