Retail Media Intel

Executive summary

Retail media's center of gravity shifted this week from growth story to scale reality. Media Partners Asia pegs APAC ads at $276.1 billion in 2026 with retail media at $75.5 billion - already 2X linear TV and 1.5X online video, heading to $110 billion by 2031 and the largest medium ex-China by 2028-29. Growth is not coming from US grocery: it is India quick commerce and Southeast Asia Shopee and TikTok Shop expansion. At the same time the definition of retail media broke: McDonald's launched the McDonald's Media Network across 450 US company-owned stores with drive-thru, kiosk, app and in-store screens, targeting a $1 billion business on 14,000 locations and 85% annual US reach, while Citi launched Citi Commerce Media to sell targeting and measurement off US card transaction data. Measurement is now the battleground, not inventory. Albertsons Media Collective launched incrementality-based multi-touch attribution with LiveRamp linking impression-level exposure across owned channels, Meta and Google to transactions for deduplicated incremental sales. Best Buy Ads answered with MTA from Sept. 30, upgraded incrementality testing, AI investment guidance, and a Circana MMM claim of 17% higher ROAS than other national media. Circana itself warned that TikTok Shop at $11 billion in Q1 2026 proves discovery and purchase now co-occur off retailer sites, demanding unified incrementality over siloed attribution. John Lewis Partnership made the same point from the UK, combining John Lewis and Waitrose loyalty signals with Epsilon for offsite CTV/streaming/display and Kevel for onsite AI targeting and closed-loop, including ROPO linkage of online exposure to in-store sales. Commerce tipped toward agentic and social checkout as real products, not demos. Google is piloting in-Gemini and AI Mode checkout for Flipkart in India, moving from shoppable listings to completed purchase in chat on the Universal Commerce Protocol with Walmart, Target, Wayfair and Shopify as early adopters, using Google Pay and UPI via Razorpay with the retailer as seller of record. Meta Muse agentic checkout with Meta Pay was cited as pressuring payments models. TikTok Shop is forcing the other side of the collapse: US sales estimated at $23.41 billion in 2026, adding Best Buy, Sephora and Ulta as enterprise sellers, launching TikTok Shop Plus membership with free shipping, and in the UK reporting 300,000 SMBs, 6,000+ daily LIVE sessions and LIVE sales up 55% year-over-year. The cross-domain connection is explicit: discovery is fragmenting to TikTok, LIVE and AI chat while monetization is consolidating to purchase-proven data. Best Buy is the template - launching on TikTok Shop with a Creator program where Best Buy Ads reuses creator content with affiliate links and paid amplification tied to first-party data and measurement, while expanding CTV via Amazon Fire TV, Insignia and FAST and testing OpenAI ChatGPT Ads. Dollar General Media Network with The Trade Desk and Kevel Ads and JLP with Epsilon and Kevel both chased the same white whale: one environment for onsite display plus offsite open-web with shared audiences and measurement. Power Digital buying pirawna and uptickk to unify DTC plus Amazon plus TikTok Shop plus retail media is agency-side confirmation that fragmented reporting is now an M&A thesis.

Market dynamics

Budget flow is running ahead of product readiness. RMNs from Kroger with Disney to Walmart with TikTok, Meta and Snap to Instacart with NBCUniversal are pitching full-funnel brand budgets on receipt-tied data and closed-loop measurement, but Digiday and follow-on analysis agree products, auctions and attribution still reward conversion, with small conversion-optimized units, high upper-funnel test costs, and trade-versus-brand ownership blocking shifts. That is why offsite CTV and programmatic extension plus incrementality proof have become table stakes for unlocking national budgets, not nice-to-haves. Tech is collapsing the funnel from both ends. On the consumer side, TikTok Shop, LIVE shopping like Boots launching Sept. 28 with No7 and THG Ingenuity fulfilment, and Sephora Drop Shop monthly drops from Sept. 19 compress discovery, consideration and purchase into video and chat. On the infrastructure side, Universal Commerce Protocol, Gemini checkout, Meta Pay agentic checkout, Wildfire RevenueEngine shoppable links across about 50,000 merchant programs, Adform agentic buying with Dell and Publicis, and OpenAI Ads Manager beta point to agents doing both buying and shopping. Self-serve tiering - Amazon DSP $50,000 managed minimums versus Trade Desk, DV360 and RMN hybrid models - will decide who captures the long tail of this automated spend. Consolidation and trust are colliding. Picks-and-shovels vendors are winning across logos: Kevel powers both JLP onsite and Dollar General onsite-offsite, Epsilon powers JLP offsite, LiveRamp powers Albertsons, Trade Desk powers Dollar General offsite even as a Seeking Alpha downgrade argues RMN giants are taking share from independent programmatic. At the exact moment RMNs ask for brand dollars and incrementality credibility, ExchangeWire catalogs Amazon soft-reserve first-price allegations affecting 1.2 million advertisers, Google exchange monopoly rulings, Trade Desk hidden-fee claims, ISBA/PwC 15% unknown delta and ANA $26.8 billion waste. Privacy-conscious, deduplicated, third-party-validated measurement is no longer positioning - it is the price of trust.

Key developments

Strategic implications

If you build retail media products, stop selling ROAS dashboards and ship incrementality as the default currency: deduplicated MTA across owned plus Meta/Google plus offsite, always-on holdouts, and MMM calibration like Best Buy and Albertsons are now making standard. That requires clean-room impression-level joins to transactions, ROPO linkage for grocers and mass, and transparent methodology that survives ISBA/ANA-level scrutiny. The second priority is true onsite-offsite unification - one audience, one buy, one measurement - following the Dollar General plus Trade Desk plus Kevel and JLP plus Epsilon plus Kevel patterns, with self-serve tiers below the $50,000 managed-service cutoff to capture SMB and mid-market. If you build commerce products, build agentic-ready now: Universal Commerce Protocol-compatible product feeds, in-chat checkout handoffs where retailer is seller of record, and UPI/Google Pay and Meta Pay rails tested in India and social paths first. Parallel to that, build the TikTok Shop operating system: LIVE ops, creator affiliate plus paid amplification, Shop Plus-style shipping/membership logic, and enterprise onboarding for brands like Best Buy, Sephora, Ulta and Boots that expect fulfilment partners like THG and measurement back to their RMN. The highest-leverage cross-domain build is creator-to-RMN attribution - ingest TikTok creator and LIVE exposure, join it to onsite search/display and CTV exposure and to transaction lift, and expose it in the same incrementality view agencies like Power Digital are trying to stitch via M&A.

Competitive landscape

Winners this week are those that connect purchase data to offsite reach and social discovery. TikTok Shop and ByteDance lead discovery commerce at $11B in Q1 and $23.41B US scale with enterprise validation; Walmart leads as both scaled RMN and UCP/agentic anchor with Target, Wayfair, Shopify and Flipkart attached; Google leads agentic standardization via Gemini checkout and UCP; Best Buy leads advanced RMN execution with CTV scale plus 17% ROAS proof plus TikTok creator loop plus ChatGPT Ads tests. Infrastructure picks-and-shovels - Kevel, Epsilon, LiveRamp, Circana - are winning across competing logos. McDonald's and Citi are the insurgent class proving QSR foot traffic and bank transaction data can price like retail data. The Trade Desk is squeezed narratively by RMN giants but remains embedded in the unification template, while Amazon faces the sharpest trust test with 1.2M advertisers cited in opacity claims even as Fire TV powers rival RMN CTV.

Action items

Trend lines

Contradictions

• Retail media networks are pitching for brand budgets via CTV and Disney/NBCU partnerships while their systems and incentives still optimize and reward lower-funnel conversion.
• APAC retail media is framed as 2X linear TV and accelerating offsite, while The Trade Desk faces a downgrade and opacity critiques question programmatic transparency and standardization.
• TikTok Shop is positioned as both enterprise mainstream marketplace with Best Buy/Sephora/Boots and as human/creator-led discovery alternative to traditional ecommerce, creating tension between scale and authenticity.
• Self-serve and automation are promoted as democratizing access via Amazon, The Trade Desk and Kevel, while walled-garden opacity and signal loss continue to limit independent measurement.

Blind Spots

• No incrementality benchmarks, profit/margin impact, or ROPO proof points to validate new measurement platforms from Albertsons, Best Buy/Circana, or Dollar General.
• Missing privacy, consent, and data-use guardrails for bank transaction data and QSR foot-traffic/app data in Citi Commerce Media and McDonald's network pitches.
• No fulfillment, returns, customer service, or unit economics detail for TikTok Shop enterprise expansion, LIVE commerce, or Google/Gemini in-chat Flipkart checkout.
• Limited SMB advertiser, European in-store execution, and pricing/sales traction signal beyond launch announcements and agency M&A.

Connections

• Best Buy's dual move into TikTok Shop storefronts and CTV-led Best Buy Ads suggests social marketplaces are becoming the offsite discovery arm of RMNs, tying creator-affiliate content directly to first-party closed-loop measurement.
• Citi and McDonald's commerce media launches plus Google's in-chat Flipkart checkout point to non-retail transaction data becoming future training and attribution fuel for agentic commerce, not just ad targeting.
• Dollar General-The Trade Desk-Kevel unification and Albertsons-LiveRamp-Meta-Google measurement together signal a shift from channel-specific ROAS to shared-audience incrementality that must span onsite, CTV, social, and agentic paths.
• APAC's retail media at 2X linear TV driven by Shopee and TikTok Shop implies discovery commerce and offsite media are the same funnel in mobile-first markets, previewing Western convergence of CTV, social, and marketplace checkout.
