A $13.5 Billion Berkshire Hathaway Mystery: What Is Greg Abel Buying Beyond Alphabet?

Berkshire Hathaway’s second-quarter filings confirmed $23.5 billion in stock purchases, the conglomerate’s first net buying in 14 quarters. Yet the documents name only one new position, a $10 billion stake in Alphabet (GOOGL).

That leaves roughly $13.5 billion in fresh buying without a name. The answer arrives by August 14, when Berkshire files its 13F, the quarterly disclosure that lists every US stock large investors hold.

The Trade Berkshire Hathaway Has Not Named Yet

Berkshire turned net buyer for the first time since 2022, and its famous cash pile finally shrank.

BREAKING: Berkshire Hathaway has begun deploying the $397.4 billion cash pile that Warren Buffett accumulated for 14 consecutive quarters.Details include:1. Instead of continuing stock sales, Berkshire was a net buyer of equities in Q2 with $19.8 billion in net purchases2.…

However, the more revealing math hides across two filings. The 10-Q shows $39.4 billion of equity purchases in the first half. However, the first-quarter report recorded just $15.9 billion of that total.

Berkshire therefore bought $23.5 billion of stocks between April and June while selling only $3.7 billion. BeInCrypto reported the Alphabet investment at $10 billion in June. Subtract it, and about $13.5 billion in quarterly buying remains publicly unidentified.

The filing offers one clue. The cost basis of its commercial, industrial and other equity bucket jumped $21.1 billion during the quarter. That category likely includes Alphabet, suggesting the mystery money targets similar businesses.

Meanwhile, Alphabet’s arrival pushed Chevron out of the top five holdings, a quiet shift from oil to technology. Warren Buffett had already offered an earlier Alphabet endorsement, so the direction surprises less than the scale.

Abel’s Fingerprints Are All Over the Filing

The repurchase section carries a detail most reports skipped. Buyback decisions now rest with the chief executive, who consults the chairman, the role Buffett retains.

Greg Abel used that authority immediately. Berkshire repurchased $4.5 billion of its own shares in the quarter, up from $235 million in the previous three months. In effect, the new chief executive declared his own stock undervalued.

The buying came from strength rather than desperation. Operating earnings climbed 16% to $13 billion, while insurance float reached $177.5 billion.

Acquisitions also drained the vault. Berkshire closed the $9.4 billion OxyChem chemicals purchase in January and completed the $6.8 billion Taylor Morrison homebuilder deal on July 24. Consequently, cash and Treasury holdings fell from a record $397.4 billion to $365.5 billion.

That war chest still towers over most markets. It exceeds every crypto asset except the Bitcoin (BTC) market cap, which currently sits near $1.31 trillion. Traders have long treated Berkshire’s cash as a fear gauge, so its first decline in years reads as a risk-on signal.

Abel has shown no appetite for digital assets so far, leaving questions about Berkshire’s future in crypto unanswered.

The August 14 disclosure will show whether the unnamed billions deepen the technology tilt or spread across old-economy names. Either way, Wall Street’s most-watched cash pile is finally moving, and the fine print now matters more than the headline.
