TikTok Adds AI Shopping Assistant as Social Commerce Tops $100B

TikTok heads into the holidays as a full shopping platform

TikTok goes into the 2026 holiday season with a new pitch to shoppers. It no longer wants to be only a place where people find products. It wants to be where they research them, ask questions, pay and send them back. Three weeks of announcements back this up. On October 5, the company launched a conversational AI Shopping Assistant. TikTok says the assistant keeps track of a user's preferences during a conversation and can answer questions about sizing, shipping and availability before helping the user check out. It also added one-click checkout, so users can buy directly from brands inside the For You feed. Shopping now reaches past TikTok Shop's own storefront and into the app's main video stream. TechCrunch reported that partners on the work include Salesforce, Shopify, Shoplazza and Stripe. The Verge added that users will soon be able to buy from outside retailers without leaving the app.28

The retail news fits the same pattern. Best Buy said it will put nearly 10,000 products on TikTok Shop starting in late October, including headphones, cameras, small appliances and laptops. That makes it one of the first big-box chains on the platform.22 Best Buy will ship the orders itself. Shoppers can return eligible items at a store or by mail.22 In the UK, Boots launched on TikTok Shop in late September. Agencies are also buying in. Common Thread Collective acquired TBAR Partners, and Simplistic acquired Tiide Commerce, both to build out their TikTok Shop services.

Returns, usually the weak point of impulse buying, got attention too. TikTok announced a partnership with Happy Returns that gives shoppers instant refunds at about 10,000 Return Bar locations across the US.26 The deals with Best Buy and Happy Returns point the same way. TikTok is building the logistics that people expect from established retailers, not just the impulse purchase.

How big is it? The numbers broadly agree

The growth figures come mostly from a small group of research firms, and on direction they agree. Momentum Works estimates TikTok Shop's global gross merchandise value at $50.3 billion in the first half of 2026, up 92% from a year earlier.1523 The US was the largest single market at $11.8 billion, up 103%. Indonesia and Thailand came next, while Southeast Asia as a whole still produced close to 70% of global volume.15 For context, the same estimates put full-year 2025 GMV at about $64.3 billion and 2021 at under $1 billion.15

The forecasts differ more. One widely shared compilation puts 2026 global GMV at $112.2 billion.24 eMarketer projects US TikTok Shop ecommerce sales of $23.41 billion in 2026, up 48%. That would make it bigger online than Target or Costco.1114 Another summary of eMarketer's outlook says only that US sales will pass $20 billion this year and $30 billion by 2028.24 A trade headline citing €106 billion for 2026, up 86%, shows how far annualized figures can drift between outlets. The safest reading is that TikTok Shop is on track to roughly double again, and that any exact full-year number for 2026 is still a projection.

The wider US market is easier to pin down. eMarketer expects US social commerce to pass $100 billion for the first time in 2026, about 18% above its 2025 estimate of $87 billion.1115 Global figures are much less settled. One market-research figure puts 2026 global social commerce at $2.11 trillion.11 An analysis comparing several firms found estimates running from under $1 trillion to nearly $2 trillion, depending on what counts as a social purchase.15 Headline trillion-dollar figures are best treated as marketing numbers, not benchmarks.

The live shopping question

The coverage disagrees most on livestreaming. TikTok's own message is enthusiastic. The company says US LIVE Shopping sales more than doubled year over year in the first half of 2026, and it expects live selling to play an even bigger role this season.2126 It points to last year's four-day Black Friday–Cyber Monday weekend, when TikTok Shop sales passed $500 million. Sellers who streamed saw 84% sales growth across more than 760,000 sessions.21

Independent breakdowns tell a more restrained story. Momentum Works and Tabcut estimate that livestreams produced only 8.2% of attributed US TikTok Shop GMV in the first half of 2026. The Shop interface produced 51.4% and shoppable videos 40.4%.15 Globally, Momentum Works put live selling at 14% of TikTok Shop volume in 2025, up from 10% the year before. Short video accounted for half.14

Both accounts can be true, and together they explain the market. Live shopping is growing fast from a small base. Recorded shoppable video and the storefront still bring in most of the money. Conversion figures for live selling vary just as much. Industry roundups cite live conversion rates of 8–12% in one place and up to 30% in another, and these come from vendor-style sources rather than audited data.1116 Only about 12% of US shoppers say they have ever bought through a livestream.11

Brand budgets seem to follow the restrained version. One industry analysis suggests putting 60–70% of commerce spending into always-on shoppable video and 20–30% into scheduled live events around launches and restocks.2 My view is that live shopping is a growing tactic for brands, not yet a main channel, at least outside China and Southeast Asia.

TikTok is also policing how live selling works. It now bans AI-generated voices, prerecorded audio and static-image content from promotional livestreams. Sellers who break the rule can face commission restrictions or lose their accounts.23 The rule matters because the company is pushing AI into ads and shopping at the same moment. Its message is that AI can recommend products, but the person selling on a stream has to be real.

Instagram's different bet

Instagram rarely appears in this round of news, and that says something. Meta stopped processing payments inside Facebook and Instagram Shops in 2025 and now sends buyers to merchants' own websites to pay. TikTok, by contrast, kept native checkout.14 Some platform guides still describe native checkout in Instagram Live, so how merchants understand the product varies by source.8 The direction Meta has taken is clear, though. Instagram still supports Shops on profiles, product tags in Reels, Stories and posts, and live shopping.39 Industry analysis says the platform favors shoppable Reels and saves live selling for major launches.2

The result is a split market. Instagram content increasingly feeds sales that happen elsewhere. A large group of Shopify apps now imports Reels into shoppable carousels and galleries on brand websites.17 Shoppable-video vendors list one-click TikTok and Instagram import as a core feature.4 TikTok is going the other way and pulling the whole purchase into its own app. Its AI assistant appears designed partly to stop users from leaving to ask ChatGPT about a product. Instagram helps brands sell through their own stores, while TikTok wants to be the store.

Why this matters now

The risks are still there. Nearly half of TikTok users report seeing possible scams from third-party sellers, and complaints about reaching customer support are common.24 TikTok's mid-year policy updates point to the same strain. They cracked down on fake tracking information, introduced AI-generated warnings about fulfillment problems, and let customer service start partial refunds on buyers' behalf.25 The ownership question that hung over the US business looks settled. A joint venture of Oracle, Silver Lake and MGX took control on January 22, 2026.24

The next test is the holiday season. TikTok's Black Friday–Cyber Monday campaign runs from November 11 to November 30.21 Best Buy's catalog, faster refunds and checkout inside the feed will all be in place for it. If live sales grow alongside them, TikTok's message will look justified. If shoppable video and the storefront keep producing most of the volume, as independent data suggests they will, the main lesson for 2026 will be more practical. Social commerce is growing because platforms have handled the routine parts of retail like checkout, fulfillment and returns, more than because of livestreaming.
