Meta's Instagram and Facebook stand to gain ad dollars as Google Search erodes because attention is shifting to quasi-entertainment platforms with authentic reach at scale. That shift is already starting and should continue: more time on Meta's platforms can attract more advertisers, accelerating both sides of the flywheel. Meta Muse offers another opportunity to use the platforms' personalized insights for results involving tasks, queries and transactions. x.com 

Agentic commerce is a bloodbath for online middlemen because AI agents that buy on a user's behalf skip the steps these companies monetize. No Google ad gets clicked, no Pinterest board gets scrolled and nobody opens Booking.com; the agent just buys the thing. Year to date, The Trade Desk is down 66%, Chewy 44%, Pinterest 31% and Booking 23%. x.com 

Alphabet's search monopoly faces a different competitive game as agent companies build their own search tools. Google Cloud grew 103%, but that was not enough to offset disappointing ads growth. Its only path is to accelerate AI training and keep spending on capex. Search will never be the same, and the risk-reward has changed, though Alphabet remains an optimistic prospect. x.com  x.com  x.com 

Meta's Reels and feed ads convert by interrupting people as they scroll. Its ad revenue grew 26%, with impressions up 10% and price per ad up 14%. By contrast, Google's search ads grew 12%, down from 19% in Q1 and 17% in Q2, as chatbot queries grow without ad dollars following. x.com 

Amazon should thrive as shopping agents spread, because agents seek the best product at the lowest price delivered fastest, and Amazon leads on assortment, prices and fulfillment. It blocks outside agents today, but CEO Andy Jassy has signaled integrations will come; Amazon is building its own agents first and must protect its large ad and sponsored-listing business while it works out agent monetization. Once it opens up, Amazon should over-index in agent-driven market share. x.com  x.com 

Amazon keeps hurting itself with its AI strategy by blocking AI shopping agents such as Muse to protect its high-margin sponsored-product revenue. That hands Shopify, which just partnered with Muse to enable agentic checkout with Shop Pay on all Shopify stores, an easy win. The tradeoff works for now because agentic shopping is a small share of volume, but if Amazon stays this stubborn it faces a long-run disintermediation threat as AI comes to facilitate something like 25% of online shopping. … Show more

Google's advertising business is losing ground to Meta and others, while Cloud, including TPU hardware sales, has not yet delivered the growth driving its AI transition. The shift from search to an AI-infrastructure "shovel seller" has not succeeded yet, so a bullish turnaround case still requires waiting for stabilization before considering a bottom. x.com 

Meta's core advertising business is significantly outgrowing its biggest competitors even before factoring in the newer businesses it is building. Q3 ad revenue rose 26% year over year, versus 10.6% at Alphabet and 10.9% at Amazon. Back at 19x forward earnings, Meta is the most undervalued Magnificent Seven stock. x.com  x.com 

Alphabet's longer AI Mode queries reveal purchase intent and agents can bring users closer to a sale, so Search will ultimately be more valuable to advertisers, not less. AI Mode searches run about 3x longer, and one in five uses voice, images or documents; sponsored product listings get about the same click-through as organic ones. For now AI Mode shows fewer ads and earns less per query, and Google has not quantified the gap. x.com  x.com 

Alphabet's search growth risks masking damage to its advertiser base. Google Ads advertiser Max Anderson says Google charges more for lower-quality clicks, weakens keyword targeting and exceeds budget caps as traditional searches shift to LLMs. This is a bear case for search, but AI capex need not fall with it: Google Cloud revenue has more than doubled, and AI spending is how Google largely defends search. x.com  x.com
