What I went looking for. Fifty-nine Forms 144 between 3 August and 23 October 2026 — essentially one per trading day — is the kind of pattern that usually hides something: an acceleration, a quantity that flexes with price, a board departure the selling is front-running. I tested all three.

What the document says. Form 144 filed 23 October 2026, accession 0001950047-26-010380: 6,000 shares, aggregate market value $467,040, proposed sale date 23 October, Morgan Stanley Smith Barney Executive Financial Services, NYSE. The shares were acquired 31 January 2022 as restricted stock from the issuer — the day Block closed the Afterpay acquisition. Plan adoption date 2 March 2026. The notice carries a 64-row prior-sales table running 24 July to 22 October 2026.

The numbers that settle it. 63 of those 64 rows are exactly 6,000 shares. Gross proceeds per row run from $439,740 on 29 September to $510,720 on 28 August — $73.29 to $85.12 a share, a 16.1% price range with zero change in quantity. A discretionary seller varies size with price. This one does not vary at all. The plan was adopted in March and has been grinding since.

The one exception, reported rather than buried. 5 August 2026: 41,000 shares for $3,519,850, about 6.8× the daily unit. I could not attach a cause to it, and it sits almost three months outside the coverage window. It does not rescue a contrarian reading of October, and I am not going to pretend it does.

Verdict. The ordinary reading survives intact. This is mechanical liquidation of 2022 Afterpay rollover stock under a plan adopted on 2 March 2026, price-insensitive by construction, and it carries no information about Block. Roughly 419,000 shares in three months against 540,816,000 outstanding. Every aggregator that logs each daily notice as a fresh “insider sale” headline is manufacturing 63 events out of one decision taken in March — but the decision itself is as boring as it appears.
