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 

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 

Meta's AI spending is weakening conversion of strong ad growth into profit and cash, making its valuation one to approach patiently, not chase. Revenue rose 26%, but operating profit excluding a legal settlement rose only about 11%; $34.9B in quarterly capex exceeded $32.8B in operating cash flow. AI has helped ads, though other factors contributed. One negative free-cash-flow quarter is not an operating failure, but depreciation could squeeze margins unless new revenue covers costs. x.com 

Alphabet's growing AI Mode query volume should expand ad opportunities as monetization catches up. Query growth hit a five-year high; AI Mode questions average three times the length and are more commercial. Schindler said lower AI Mode monetization weighed on Search growth of 12%; total ads slowed to 11%. Ads are expanding overseas, and US multi-turn tests already match product-listing click-through rates. The slowdown does not mean search demand is broken. x.com 

Meta's AI-orchestrated ad growth makes criticism of Zuckerberg misplaced. The business is growing in the upper 20s, versus 12% for Google Search. x.com 

Meta's hundreds-of-gigawatts compute ambition looks hard to justify against the revenue a much smaller build might support. If Anthropic can generate over $70B in annualized revenue on 3GW or less, including training, hundreds of gigawatts is not a serious figure. Earlier Muse monetization than in past product cycles also makes little sense without direct integration into ad recommendations or an immediate shift in user behavior. x.com 

Meta's ad engine is still growing, and its higher AI spending comes with a stronger revenue outlook. Revenue was $64.6B versus $63.4B expected, with $63.1B in ads; the Q4 guide midpoint of $74.5B beat $73.7B expected. Meta raised only the capex floor to $135B, leaving the $145B ceiling unchanged. The roughly $10B legal charge depressed reported EPS, not ads. Overweight, $1,004 target with 41% upside. 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 

Meta's expected $700 billion share raise would dilute investors while a non-voting class preserves Zuckerberg's control. With AI bond financing effectively closed, that is how it plans to fund its needs. X's growing ad inventory should lower ad prices enough to pull small advertisers' budgets away from Meta. x.com  x.com  x.com 

Meta's growing revenue and ad impressions show Zuckerberg knows what he is doing. Revenue rose 26.1% year over year to $64.6 billion, while ad impressions increased 10% year over year. x.com
