AI agents will reprice anything priced per human decision, so rails like identity and payments beat the persuasion, and the repricing has barely started. Click pricing compresses as agents take over sessions; transaction take rates hold. Search ads carry most risk, as Alphabet prices agent-shaped queries per human click; AppLovin and The Trade Desk are riskiest. Amazon and Walmart own the transaction, Meta, Snap and Pinterest feeds are safer than bears think, and Tencent's WeChat is best placed. … Show more

Alphabet's search advertising is under attack as chatbot queries grow without matching ad revenue. Google blamed AI Mode on its earnings call. Search ads grew 12% and missed estimates, down from 19% in Q1 and 17% in Q2. Sentiment has completely flipped bearish as its search business shows signs of being eaten by AI. 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 

AI disruption of Google's search business remains a reason to be bearish on Alphabet. Rose had reached a similar view before Drew Cohen argued that shopping and travel agents could divert monetizable searches from Google's sponsored ads. The stock's rise has not changed that bearish view. 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 

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 

Changing search habits may threaten Alphabet's Search business. Personal search use has changed a lot, and that looks likely to become a broader trend. Search remains a real concern; buying more Alphabet right now looks unlikely. x.com  x.com 

Alphabet's five-point Search growth slowdown does not look concerning because FX was the biggest drag, alongside World Cup budget timing, an AI Mode monetization gap, APAC retail disruption from EU de minimis changes and a tougher comparison. Query growth hit a five-year high; AI Mode ad load is set to ramp after successful experiments, with ads expanding beyond the US. x.com  x.com 

AI search threatens Google's advertising economics because it competes with the ad business itself, potentially reducing the value advertisers receive. The bear case is that AI eats Google's Search ad business faster than Google's AI spending pays for itself. x.com  x.com  x.com
