TikTok and Meta Turn Advertising Week Into an AI Checkout Pitch: This Week in Social

The week in brief:

• TikTok announced Buy Direct at Advertising Week, a one-click checkout that lets people buy from a brand's video without leaving the For You feed.
• Meta's AI business assistant can now use a client's past campaign results and imported brand guidelines, and Meta is testing a Shopify checkout inside Messenger.
• Advertising Week named Dhar Mann its first Chief Creator Officer, with a public goal of $100 million in new creator-brand business within a year.
• Ofcom opened its first Online Safety Act investigation into Meta, over the risk assessments behind Instagram Instants.

Advertising Week New York spent four days convincing the industry that AI agents are about to do the buying, the selling, and the lead-qualifying that used to sit inside an agency's job description. TikTok handed its checkout button to an algorithm. Meta gave its ad assistant a memory. A creator got a budget line and a trade show title. And in the middle of all of it, the UK opened its first-ever formal investigation into Meta, not over an ad product, but over a messaging feature nobody was watching closely enough. Four stories, one week, and a real answer underneath all of them about who's actually accountable when an AI agent closes the deal.

TikTok just put a checkout counter inside the feed, and killed "link in bio" in the process

TikTok used its October 5 keynote at Advertising Week to unveil a package of agentic commerce tools, and the headline feature is Buy Direct: a one-click checkout that lets someone complete a purchase from a brand's content without leaving the For You feed, on a separate purchase path from the existing TikTok Shop storefront (Music Business Worldwide). Alongside it, Shopping Assistant is a conversational tool that walks a shopper through sizing, shipping, and availability inside the same chat, and Agentic Leads is an AI agent built specifically to capture, qualify, and convert high-intent prospects for lead-gen advertisers. Salesforce, Shopify, Shoplazza, and Stripe are named launch partners.

The quieter number might matter more. TikTok also opened its ad network to US advertisers for the first time, a network that reaches close to 400,000 apps outside TikTok itself, and it revised GMV Max to factor affiliate commissions, coupons, and referral fees into how it optimizes TikTok Shop spend. TikTok cited Kantar research claiming 84% of marketers already advertise on the platform, with a net 75% planning to increase spend on AI assistants specifically in 2027. None of this shipped with firm launch dates attached, so treat it as a roadmap, not a switch that flipped overnight.

Here's what agencies should actually do with it: stop writing TikTok content as a teaser for a destination outside the app. If Buy Direct and Agentic Leads work as described, the entire funnel, discovery through purchase or lead capture, will live inside the scroll with zero clicks out. A client's content that depends on someone leaving the feed to buy or inquire is building for a funnel that's about to get shorter. Start auditing product and lead-gen content now for whether it can close the sale on its own, because soon it might have to. On Instagram and Facebook, where caption links are already capped, the same logic applies; see how to get clicks when link posts are capped.

Meta gave its ad assistant a memory, and quietly put a Shopify checkout inside Messenger

Meta made its own Advertising Week push on October 6, and the centerpiece is a meaningfully upgraded AI business assistant. It can now draw on a client's past campaign performance, seasonality patterns, and previously stated goals, and advertisers can import brand voice guidelines and strategy documents directly into it. Meta is also testing scheduled tasks that let the assistant deliver recurring performance reports and alerts without being asked (TechJuice). Advantage+ Creative's video generation tool, which turns static image assets into video ads, is now generally available after a limited rollout earlier this year, and Meta opened its server to third-party AI tools so outside platforms can connect directly into its advertising infrastructure. On the commerce side, Meta paired all of this with a direct checkout built with Shopify, running through its Business Agent on Messenger.

Read next to TikTok's announcement, the pattern is obvious: both platforms spent the same week moving checkout off their own storefronts and into whatever surface the customer is already looking at, whether that's a feed or a DM thread. If you're running paid social for clients, the assistant upgrades are the part worth testing first, specifically whether letting it hold onto a brand's actual strategy documents produces meaningfully better first drafts than the generic version did. That's the difference between a tool that saves an account manager an hour and one that still needs a full rewrite.

A creator is now running deal-making for the entire ad industry, with $100 million on the table

Advertising Week named Dhar Mann its first-ever Chief Creator Officer this week and set a public target: help launch $100 million in new creator-brand business within the next 12 months (Digiday). The number isn't $100 million in signed contracts from a four-day event. Mann was upfront about that, pointing out that brands allocate Q4 budgets in Q1 or Q2 and aren't going to unlock dollars that didn't already exist. What the week actually produced was a string of deliberately engineered introductions: "Creator Karaoke" paired 25 creators with 25 senior brand decision-makers, "Creator Omakase" built an entire dinner around brands handing creative control to creators against real business objectives, and the week closed with a six-hour "Dhar Creator Day" that replaced panels with interactive sessions. Mann also announced Creator City, a four-acre production campus from Dhar Mann Studios opening in Los Angeles for Super Bowl weekend in February 2027.

The part worth sitting with isn't the dollar figure, it's the title. A trade show just created a formal, named executive role whose entire job is engineering creator-brand matchmaking at scale. That's a service line, not a vanity hire, and it's exactly the kind of structured introduction work that smaller agencies have been doing informally for years without ever pricing it as its own product. If you've been treating creator sourcing and matchmaking as a favor you throw in with a retainer, this is the week to start pricing it as a standalone line item instead.

The UK just opened its first Meta investigation, and it's about a disappearing-DM feature

Separate from everything happening at Advertising Week, Ofcom opened a formal investigation into Meta on October 6, its first-ever case against the company under the UK's Online Safety Act. The question is whether Meta carried out the required illegal-content and children's safety risk assessments, under sections 9(4) and 11(4) of the Act, before launching Instagram Instants, the feature that lets people send photos and videos through Direct that disappear after viewing (TechRepublic). Ofcom has been explicit that opening a case isn't a finding of wrongdoing; it will gather evidence first and only issue a provisional decision if it finds a likely breach, which Meta could then respond to before any final ruling. The exposure if a breach is found is real: orders to comply, orders to remedy harm, and a fine of up to £18 million or 10% of Meta's qualifying worldwide revenue, whichever is greater. Meta says it ran a risk analysis and briefed Ofcom about Instants multiple times before launch, and that the feature already blocks screenshots, reshares, and forwarding.

This is the story that should actually change how agencies think about the other three. Every one of this week's commerce and AI announcements assumes a client is comfortable handing more of the transaction, and more of the audience relationship, to a feature the platform controls end to end. Ofcom just opened a case specifically because a messaging feature shipped without, in the regulator's view, enough scrutiny of what it would mean for the people using it. If a client is running campaigns through disappearing content, don't let the platform's own vanishing message be the only record that a conversation, a promise, or a response ever happened. Keep your own logs and timestamps outside the feature that's designed to not keep any.

None of this week's four stories are really about one platform. They're about who holds the receipt when an AI agent closes a sale, books a lead, or deletes the evidence of a DM thread. The agencies that write that answer into their own client contracts and reporting this quarter will be the ones who aren't scrambling to explain it when a client, or a regulator, asks for it in Q1.
