Greg Abel's first 13F added about 40 million Delta Air Lines shares worth roughly $2.6 billion. [1] The position landed in a week Brent crude rose 7.84 percent to $109.26 and WTI rose 10.48 percent to $105.42 — the largest weekly oil gains since the Iran war began. [2]

The paper's Friday major on the filing as a filing argued the document, not the succession narrative, would be the artifact worth reading. The Delta line is the artifact's most contrarian sentence. Buying an airline at scale against a Hormuz disruption that has no enforcement mechanism in the Trump-Xi readout is a fuel-cost call no one in public markets is currently making out loud.

Two readings are possible. The charitable one is that Berkshire is pricing the next twelve to twenty-four months — a window in which oil could mean-revert if the strait stabilizes, and Delta could re-rate against peers who let their pre-pandemic balance sheets discipline them. The harsher one is that the Delta position is a Buffett-era reflex inside an Abel-signed filing, the kind of decision that survives the succession because no one wanted to fight about it on Week One.

Either reading is testable. Delta's Q2 fuel hedging disclosure, its summer capacity plan, and its August earnings call will price the bet faster than any 13F can. [1] Berkshire bought an airline into the worst oil week of the war. That is the position to mark.
