⚠️📉Buffett's own Google bet just lost $8.2B in a single day

$GOOGL dropped 13.7% today to $279.6. That's the worst day in its history.

Berkshire owns about 106M shares across Class A and Class C. At the end of Q2 that stake was worth around $37.8B. Now it's about $29.6B.

And it might already be underwater. Berkshire never shared its cost basis, but most estimates put it somewhere around $300–320. At $310 a share, that's roughly a $3.2B paper loss. At $300, it's about $2.2B. #GOOGL #buffet

📝Q2 13F filings pointed to three things, all in the same direction: sovereign funds and passive giants were adding SpaceX, semis were "long Micron, split on Nvidia," and AI infrastructure had become its own sector.

1.SpaceX became a "non-listed anchor." Saudi PIF's US equity portfolio jumped from $12B in Q1 to $37.9B in Q2 — almost all of it from a new SpaceX position. Temasek, BlackRock, ARK, Point72, and Fisher all opened or added positions in the same quarter. A company that hadn't even listed yet, getting bought simultaneously by sovereign funds, passive giants, and active hedge funds — that kind of alignment is rare in 13F history.

3.consensus and divergence inside semis. Adding Micron was near-universal, but Nvidia was the split point. Passive giants kept adding (JPMorgan $87.6B, Goldman $38.4B, ARK +33%), while active funds were exiting (SoftBank fully sold in 2025 Q4 for $58.3B, Point72 cut, Leopold disclosed an $8.5B put short including NVDA in May). Passive money in, smart money out — that kind of split usually signals the mid-to-late stage of a trend.

3.AI infrastructure became its own sector. Leopold went all-in on memory, power, cloud compute, and Bitcoin miners pivoting to AI hosting. BlackRock's $13.3B in Q2 crypto-related net buying put 78.5% into the same miner stocks. Not betting on AI models — betting on the shovels.

Q3 2026 13F won't drop until mid-November, but the Q2 consensus is already clear: SpaceX is the non-listed anchor, Micron and AMD are the new semi consensus, NVDA is the divergence point, and AI infrastructure is an independent sector.
