Apostra Bets on Agentic Ad Layer
Scope3 has rebranded as Apostra, pivoting from its original carbon emissions calculator mission to focus on enabling agent-to-agent ad buying and selling. The company, led by adtech veteran Brian O'Kelley, has been building agentic advertising infrastructure since early 2025, including the Ad Context Protocol (AdCP) open standard and a platform that allows AI agents to negotiate and execute media buys. Apostra has already managed $1.2 million in media spend over the last three months, with clients in the U.S., U.K., France, Brazil, the Netherlands, and South Africa. The company faces competition from the IAB Tech Lab's AAMP 3.0 standard, which also aims to standardize agentic media buying. O'Kelley acknowledges the shift away from sustainability but argues AI is the biggest growth area. The article questions whether the industry needs such a neutral layer or if open standards suffice.
A major rebrand and pivot by a key adtech player (Scope3) into the emerging agentic advertising space, with the launch of a competing protocol and market traction, signals a significant shift in adtech infrastructure.

Meta Muse Launch entfacht Debatte über Agentic Commerce
Der Start von Metas persönlichem Assistenten Muse, unterstützt durch nationale Werbung und ein eigenes Gerät, signalisiert einen großen Vorstoß in den Bereich der Consumer-KI-Agenten. Der Markt reagierte stark: Instinct, ein konkurrierendes Agent-Startup, strebt offenbar eine Bewertung von 10 Milliarden US-Dollar an, während Shopify eine Partnerschaft für den Agentic Checkout ankündigte. Die Einführung hat jedoch auch Ängste vor einer Disintermediation in den Bereichen Reise, Banken und Abo-Medien ausgelöst. Amazon blockiert Muse, und Expedia-Aktien sanken trotz einer Integration. Der Artikel beleuchtet die technischen und geschäftlichen Herausforderungen, darunter CAPTCHA-Probleme, Restaurant-Reservierungs-Schwärme und die Notwendigkeit einer neuen Commerce-Infrastruktur für autonome Agenten.
IAB Tech Lab Introduces AAMP 3.0 to Standardize the RFP-to-Buy Process for Agentic Advertising
IAB Tech Lab has announced AAMP 3.0, introducing OpenProposal, a specification to standardize the RFP-to-buy process for agentic advertising. OpenProposal enables AI agents to discover, compare, and negotiate media proposals by defining machine-readable proposal data across eleven headers in categories like Merchandising, Optimization, Commitment, and Reconciliation. It is transaction-type agnostic (supporting Direct IOs, Programmatic Guaranteed, etc.) and channel agnostic (covering display, CTV, audio, OOH, linear TV). Additionally, IAB released the Measurement Services Addendum v1.0, a contractual framework for measurement, verification, attribution, and analytics services. Both initiatives are open for public comment until October 22, 2026, and aim to improve efficiency and standardization in programmatic media buying and measurement.
Meta's AI Agent 'Muse' Tops App Store, Surpasses ChatGPT
Meta has launched a new AI agent app called Muse, which quickly climbed to No. 1 in Apple's App Store, surpassing ChatGPT. Muse is designed to handle everyday tasks such as making dinner reservations and appointments, and Meta plans to take a small percentage cut from transactions. The app's popularity has contributed to a $170 billion increase in Meta's market cap since its unveiling. Muse leverages Meta's vast user base and data, potentially enhancing ad targeting and pricing. A hands-on test by the author showed Muse successfully booking a dinner reservation in under a minute, outperforming Claude, ChatGPT, and Gemini. The article also covers other topics including EU-Canada trade tensions and Federal Reserve interest rate hikes.
