5 Billionaire Money Managers Dumped Palantir in the Second Quarter. This Is the AI Applications Stock They're Buying Hand Over Fist Instead.

13F filings show a split: five billionaire managers sold Palantir in the June-ended quarter, while four billionaires (plus Berkshire) added to Alphabet. The article highlights Alphabet Q2 FY26 results with revenue +24% Y/Y to $119.8B (+$2.8B beat) and Google Cloud revenue +82% Y/Y to $24.8B, with operating margins up to 34% at the consolidated level and 36% at Google Cloud. Despite this strong growth, Palantir’s valuation is flagged as stretched (P/S ~73 vs >100 at entry to the year), leaving the overall message mixed.

Analysis

The cleanest signal here is not “AI is good” but that capital is rotating from narrative-maximizers to cash-generating AI compounding stories. That favors GOOG/GOOGL and punishes PLTR on the margin: if the market stops rewarding every incremental beat with multiple expansion, PLTR’s valuation can re-rate far faster than fundamentals can catch up. The second-order effect is broader for high-multiple software: if PLTR loses sponsorship, the entire AI applications cohort can see derating pressure even without any change in revenue growth.

Alphabet looks better because it monetizes AI from a position of distribution control and balance-sheet capacity, not just product enthusiasm. The key mechanism is that AI can widen the monetization gap between incumbents and challengers: Alphabet can amortize AI capex across search, YouTube, and cloud, while PLTR must continually prove incremental contract wins and retention to justify its premium. Over 1-3 months, the catalyst is continuing 13F/earnings confirmation; over 6-18 months, the story is whether cloud AI margins stay high enough to offset search disruption risk.

Contrarian take: the consensus may be over-reading 13Fs. Some PLTR selling is likely portfolio construction after a massive move, not a fundamental indictment, and that matters if revenue re-accelerates or margins expand again. Conversely, GOOG is not risk-free: if AI capex rises faster than monetization, operating margin could compress and the stock could stall despite “best-in-class” sentiment. Falsifiers are straightforward: PLTR must show accelerating commercial growth and durable free-cash-flow conversion; GOOG would be challenged by any sign of AI monetization lag or fresh regulatory shocks.

Key Decisions for Investors

• Pair trade: long GOOG/GOOGL vs short PLTR into the next earnings cycle; thesis is multiple durability for GOOG versus valuation fragility for PLTR. Use a 1-3 month horizon and cover PLTR if it re-rates below ~50x forward sales or if guidance meaningfully accelerates.
• If you want lower beta exposure, buy GOOG calls or a call spread 3-6 months out rather than common; upside is driven by continued cloud/ads monetization, with risk capped if AI capex narrative turns negative.
• Avoid initiating fresh long PLTR at current levels unless the next print confirms both commercial growth acceleration and margin expansion; otherwise treat it as a watchlist short on any post-earnings strength.
• For basket exposure, favor XLC/QQQ over IGV until AI software valuations normalize; if PLTR drags the group lower, use that as the entry point rather than chasing the first selloff.
• Set a thesis trigger on GOOG: if operating margin rolls over meaningfully while cloud growth decelerates, fade the long and reassess the AI monetization premium.
