↓ -11%Man raises racial profiling concerns after he alleges differential treatment over cuticle clippers at Walmart: 'I see what's going on' Fair point. Mikewillcutsmp is accusing a Walmart employee of treating him differently while he shopped. In a TikTok video he captioned "Store Policy...or Racial Profiling," Mike said he went to an outlet of the retail chain and looked for cuticle clippers in the beauty department. He noted that the items were locked and that a woman was already waiting in the section for her item to be unlocked. When an employee eventually arrived, the woman allegedly left with her item, but Mike claims that when it was his turn to retrieve his, the employee told him she needed to put it in a box. Mike sensed something was wrong and immediately confronted the employee. "I said, 'Well, why didn't the lady have to put her stuff in a box? The one that you just held, the one that just grabbed the items before I did and walked away,'" Mike recalled telling her. He said the employee tried to justify her actions by claiming that the products were different, but he kept emphasizing what he observed. He allegedly told her, "We grabbed from the same little, you know, door, like we were standing next to each other. Why do I have to put my item in a security box? She got to walk away with hers." The employee apparently apologized, but Mike wanted to escalate the matter to a senior. "I see what's going on. I'm gonna go tell your manager," Mike recounted. The footage then shows him approaching a man and requesting to speak with the employee's supervisor, who turns out to be the manager. In the video, Mike recounts his experience to the manager, who then asks him to describe her appearance. When Mike identified her as a "short" Filipino woman, the manager confirmed he knew whom Mike referred to and apologized for the employee's behavior. Mike ended his video by thanking the manager for helping him in this situation. He said, "Got a brother as a manager and he know...I wasn't wrong about what I felt." "Good job for sticking up for yourself" Some people in the comments appreciated Mike for standing up for himself. One person wrote, "Good job for sticking up for yourself." Another said, "I'm so glad you reported it to the manager." A few people questioned Mike's decision to still buy the items despite what happened. One person commented, "Stop shopping at Walmart you find those cutter at Tj max." Another remarked, "And you still made the purchase at Walmart..." A handful of people shared their experiences with Walmart. One person said, "They tried me while wearing a $2k YSL bag and paying with an Amex Platinum. It's not about your ability to pay, it's about their ability to degrade you. I NEVER went back and never will." Another spoke about having an experience mildly similar to Mike's. The wrote, "I just left Walmart because everything I needed was locked up. My usual Walmart don't have anything locked up. Just grab and go. Should've went there instead." Walmart and Target have recently faced criticism, mainly fuelled by online rhetoric stemming from numerous complaints. This has led to calls for a boycott. Although social media discussions show some people are boycotting, many still shop there because these stores are undeniably convenient and resourceful, especially when you need something quickly.

Meta, Walmart and Stripe develop standard for personal AI agents. The protocol aims to help businesses authenticate agents acting for customers and manage their access to personal and payment information. Published Oct 6, 2026, 2:23 PM EDT Meta, Walmart, Stripe and Sierra are developing an open protocol for personal AI agents doing business online, aiming to help companies verify who an agent represents and control its access to customer information. The proposed personal agent protocol would set standards for how personal AI agents interact with businesses. Sierra, an enterprise AI startup co-founded by OpenAI Chairman Bret Taylor, is part of the effort, which Taylor is leading. The protocol is intended to help businesses distinguish agents acting for customers from bots operating without a person's authorization. Taylor likened its authentication function to signing in to websites with Google or Facebook credentials, and said it could give companies visibility into what agents do on their services. Discover more Market trend reports Bitcoin price tracker Ethereum investment guide Meta Superintelligence Labs head David Singleton said the standard is designed to give customers more visibility and control as agents use sensitive information, including credit card and personal details. He compared the planned framework to email standards that let different systems communicate. OpenAI and Anthropic have not joined the initiative. Taylor said he expects other AI companies to take part and argued that broad participation is central to making the protocol an open standard.

Stripe, Meta, Walmart, and Shopify are building the infrastructure for AI agents to shop for you. A wave of new protocols and integrations is turning AI assistants into autonomous shoppers, with agentic purchases through Stripe Link surging 38-fold in a single month. 2 hours ago Meta official logo (public domain, Wikimedia Commons) - CryptoBriefing brand treatment Sponsored: Vera - AI-powered prediction market intelligence, built for serious analysts Explore Vera A coalition of major technology and retail companies is quietly rewriting the rules of online commerce, moving from a world where you click "buy" to one where your AI agent does it while you're doing something else entirely. Meta, Sierra, Genesys, Rocket, Shopify, and Walmart have announced work on the Personal Agent Protocol, an open standard designed to let personal AI agents interact directly with businesses on behalf of their users. The numbers behind the shift. The commercial stakes are not abstract. Stripe's Link digital wallet, which counts approximately 300 million users and connects to around 1 million merchants, has seen agentic purchases surge 38-fold over the past month leading into late September 2026. Meta's AI assistant, Muse, launched on September 8, 2026, as the first personal agent to integrate with Stripe Link, giving it the ability to complete purchases through one-time virtual cards or stored payment credentials. Within two weeks of launch, Muse added Shop Pay and PayPal integrations, and it became the first agent to offer purchase protections to users. Walmart is positioned as a major connector within the Muse ecosystem alongside other large retailers. AI, tech, and the markets they move - in one daily briefing. Daily. Free. Join 34,000+ readers across crypto, finance, and policy. A fragmented standards race. Walmart and Shopify are also participants in the Universal Commerce Protocol, co-developed with Google, Target, Etsy, and Wayfair, which is designed to cover the full arc of an agent-initiated checkout process. Stripe, for its part, co-developed the Agentic Commerce Protocol with OpenAI, released under Apache 2.0 in September 2025, to streamline checkout flows for AI-driven transactions. Stripe also launched the Machine Payment Protocol with Tempo in March 2026 to address how machines, rather than humans, handle payment initiation. Genesys expanded its own collaborations with Meta and others in September 2026, focusing on agentic customer experience orchestration using protocols including A2A and MCP. What this adds up to is a landscape where several overlapping and competing protocols are vying to become the standard layer through which AI agents transact, with no single framework yet dominant. Why this matters beyond the tech. The shift from chat-based AI assistants to transaction-capable agents is a structural change in how consumers engage with retail. A chatbot that recommends a product is useful; an agent that buys it, tracks shipping, and handles returns on your behalf is a different category of tool entirely. Muse's decision to include purchase protections from the start signals that the companies building these agents understand that trust is the real bottleneck to mass adoption, not the technology itself.

ShipStation launches Ship with Walmart. Walmart Marketplace sellers can access discounted shipping labels from trusted carriers and access seller protections - all within the ShipStation workflow October 6, 2026. 10:02 AM AUSTIN - ShipStation, a leading intelligent shipping and logistics platform for small and mid-sized businesses, announced the launch of Ship with Walmart, a new shipping solution that gives Walmart Marketplace sellers direct access to Walmart-negotiated shipping rates within the ShipStation platform. The integration allows sellers to purchase eligible labels, access seller protections, and manage Walmart Marketplace orders directly within their existing ShipStation workflow. Many Walmart Marketplace sellers manage orders across multiple selling channels, with ShipStation serving as the hub that brings those workflows together. Ship with Walmart extends that capability to Walmart Marketplace orders: sellers can activate it through ShipStation and purchase eligible labels alongside their existing carrier accounts, with no new integration to build. Ship with Walmart works alongside a seller's existing shipping setup as an additional option and activation is simple by design. "Sellers shouldn't have to choose between the tools they rely on every day and the benefits their marketplace offers them," said Matt Norman, vice president, Strategic Business Development, ShipStation. "Ship with Walmart closes that gap. Sellers get Walmart-negotiated rates and seller protections, including up to $100 of order protection, all within the ShipStation platform." With Ship with Walmart, sellers gain access to: Walmart-negotiated rates: Discounted rates from trusted domestic carriers. On-time delivery and valid tracking support: Ship with Walmart supports on-time delivery and valid tracking performance. Seller protection for lost packages: Eligible orders shipped on time can receive up to $100 in protection for lost-item claims, including lost-in-transit and after-delivery claims. Sellers can also access negative feedback review for approved lost-item claims. Delivery promise, connected to carrier choice: Simplified Shipping Settings surfaces Walmart-recommended carrier and service-level options directly in ShipStation, based on the seller's delivery promise. A unified, multichannel dashboard: Walmart Marketplace orders sit alongside Amazon, TikTok Shop, Shopify, eBay, and other connected storefronts in one place - sellers don't have to step outside the ShipStation workflow they already know to manage Walmart shipping. Purchase labels directly in ShipStation: After activation, sellers can purchase eligible Ship with Walmart labels within their existing ShipStation workflow. Walmart Marketplace sellers who are new to ShipStation can receive 20% off their ShipStation subscription for one year when they activate Ship with Walmart.* "For Walmart Marketplace sellers, every operational advantage matters, and shipping is one of the biggest levers they have to protect margins and delivery performance," said Norman. "Ship with Walmart delivers real, negotiated value inside the platform sellers already use." Ship with Walmart is available now to Walmart Marketplace sellers using ShipStation, and activation is simple. Ship with Walmart in ShipStation currently supports U.S. domestic shipments only. *The ShipStation subscription offer can be used alongside discounted Ship with Walmart label rates. Eligibility requirements and offer terms apply.
Walmart moves to grab a bigger chunk of the TV ad business. Oct 6, 2026, 6:00 AM PT Walmart is taking its ad business to the TV screen. On Tuesday, Walmart exclusively told CMO Insider that advertisers can now use its shopper targeting and measurement data on linear TV through a new partnership with Warner Bros. Discovery, which is merging with Paramount to form Skydance. The move positions Walmart more favorably in its pursuit of the big brand budgets traditionally spent on TV, and beyond the performance marketing spend that typically accounts for the largest share of its Walmart Connect ad business. It's also the latest sign of retail media giants further expanding into new media beyond their own stores, sites, and apps. Walmart's pitch to advertisers is that they can reach its millions of shoppers and measure whether those ads drove purchases through its sales data. Those properties naturally have a finite amount of advertising inventory, so the company has been ramping up efforts to help advertisers target Walmart shoppers elsewhere. Walmart acquired the TV-maker Vizio in 2024, helping it tap into connected-TV ad budgets. This year, it scooped up the adtech firm Vibe.co, which also focuses on streaming TV, as part of a plan to pursue small- and medium-sized advertisers. Walmart's ad revenue reached $6.4 billion in 2025. Khurrum Malik, Walmart Connect VP of business and product marketing, told CMO Insider the WBD deal came about because advertisers and agencies had asked for the capability. Advertisers' audiences are split across CTV and linear, but advertisers want consistent targeting and measurement across both, he said. Walmart advertisers can access this linear inventory via a private marketplace deal on its demand-side platform. It includes WBD networks such as TBS, TLC, and TruTV, and can include live sports when those networks carry them. Walmart has experimented with linear TV before: In 2024, it partnered with NBCUniversal to make "shoppable" ads available on its live Thanksgiving sports programming. Malik said he envisioned Walmart expanding into more non-digital channels. "We want to start slow and then go fast," Malik said. "I could see us scaling as the solution works for advertisers." Walmart isn't alone in chasing TV ad budgets in the fast-growing retail media space. Arch-rival Amazon - whose ad business reached $68 billion in 2025 - has spent years extending its trove of shopping data into streaming TV on Prime Video and through partnerships with Netflix, Disney, and Roku. Walmart is trying to differentiate itself by making its data available through competitor ad-buying tools, too. Also on Tuesday, Walmart announced that Yahoo DSP advertisers can target its audiences on Vizio and other CTV publishers through a partnership with the supply-side platform Magnite. Additionally, it announced a partnership between the Walmart DSP and Spotify across audio, video, and display ads. "We want to make it easier for them to buy how they buy today, instead of forcing somebody into one DSP that really conquers them all," Malik said. "I think about us as a friendly garden," he added. That's in contrast to "walled gardens" - like Meta or YouTube - that require advertisers to use the platform's own buying tools to access its ad inventory. Kevin Dunn, chief revenue officer of Experian Marketing Services, said he expects more retail media to move "offsite" into CTV and other web properties. "I expect the conversation to shift from 'which networks should we be in?' to 'how do we make them work together?'" Dunn said. The retail media space is growing rapidly, with spending set to top $203 billion this year, per Business Insider sister company EMARKETER. However, with more than 200 retail media networks worldwide, the space is becoming increasingly crowded, and some advertising pros have been calling for more consistent standards and language for measuring their effectiveness. A recent ISBA and MediaSense audit of five UK retail media networks found inconsistent metrics across them, including five different definitions of an "attributed sale." Malik said Walmart works with third-party measurement firms alongside offering its own first-party data. "As commerce media moves into a broader media mix, its accountability has to go with it," Malik said.
