InMobi Acquires MobileAction to Boost iOS Ads
India-based ad tech firm InMobi announced the acquisition of Apple-focused advertising startup MobileAction (terms undisclosed) as part of a push to strengthen its Apple Ads capabilities. InMobi executives say iOS ad demand has been underleveraged due to signal loss, limited Apple inventory and the specialized tools required to compete there; they note Apple is expanding ad placements across Maps, News, and new search/sponsored units. The article also highlights industry caution about agentic AI in media buying after examples of AI agents hallucinating prices or misbooking campaigns, and reports on related industry moves including The Trade Desk strategist Samantha Jacobson moving to OpenAI and Smartly finalizing an acquisition of INCRMNTAL.
Acquisition strengthens an AdTech vendor's iOS advertising capabilities at a time when Apple is expanding ad inventory; relevant to buyers and sellers targeting iOS but not industry-shifting like platform policy changes from Google/Apple.

InMobi and Scope3 Launch Sell‑Side AI Agent
InMobi has partnered with Scope3 to debut a sell-side AI agent that autonomously represents and sells premium Glance ad inventory. The agent will operate via Scope3’s Interchange agent-to-agent media platform and use the open Ad Context Protocol (AdCP), an industry standard driven in part by Scope3 CEO Brian O’Kelley and other coalition members such as Yahoo and PubMatic. InMobi and Glance will pilot the system in the coming weeks; the company did not name participating brands. InMobi argues agent-to-agent workflows are better suited for context-dependent, commerce-style inventory (like Glance lock-screen and in-app shoppable experiences) than traditional programmatic DSP/SSP pipelines. InMobi recently acquired AI app-analytics firm MobileAction and expects agentic transactions to grow over 2026–2028.
InMobi Launches First Agentic Seller with Scope3
InMobi Advertising announced a strategic partnership with Scope3 to launch the industry’s first “agentic seller,” enabling AI-powered buying agents to access InMobi’s premium mobile in-app and exclusive CTV inventory — including Glance — through a single connection on Scope3 Interchange. The integration uses the AgenticAdvertising.org Ad Context Protocol (AdCP), allowing buying agents to submit briefs and receive matched inventory, audience signals, and campaign parameters in minutes instead of days. The deal aggregates roughly 2 billion InMobi mobile users and Glance’s 300 million first‑party active devices under one AdCP connection. Pilot campaigns are expected to go live in the coming weeks.
TSMC Q3 Revenue Up 51% to Record, Stock Falls
TSMC reported a 51% increase in third-quarter revenue to 1.49 trillion Taiwan dollars (EUR 41.7 billion), surpassing expectations. The semiconductor giant, a key supplier to Apple and Nvidia, continues to benefit from the AI boom and strong chip demand. However, the stock declined despite the record results. The company plans to invest EUR 52-56 billion in expanding its manufacturing facilities this year, including a joint venture with Sony for image sensors. TSMC's market capitalization is approximately USD 2.45 trillion, making it the most valuable company outside the US. The company's growth is also boosting Taiwan's economy, with exports rising over 70% in August and GDP expected to grow 11% in 2026.
