The period balance: money in, money out
In the Form 4 filings submitted between Aug 25, 2025 and Oct 19, 2026 there is not one open-market purchase of Block, Inc.: 152 sales worth $98.3M and zero dollars bought.
Only codes P and S count, where an insider puts in or takes out their own money. A selling balance like Block, Inc.'s is the norm in the S&P 500, where much of the pay comes as stock. It is not a recommendation to buy or sell: it is what was filed.
Every transaction, code by code
| Code | What it means | Trades | Reported amount |
|---|---|---|---|
| S | Open-market sale | 152 | $98.3M |
| A | Grant or award | 46 | $64k |
| F | Tax withholding (shares surrendered for taxes) | 21 | $11.4M |
| Total | Everything filed in the period | 219 | $109.8M |
40 of the 219 rows carry no usable amount on the Form 4: they count as trades and add $0. The code labels come from the SEC index.
Who has traded
Over the 15 months of history, 17 distinct people or entities have filed Block, Inc. transactions: none bought on the open market and 8 sold. Counted by CIK, the fixed number the SEC gives each filer, and not by name, which each filer types their own way.

How to read this data
18 of the 20 sales in the table are flagged as scheduled (10b5-1 plan): signed months ahead and executed automatically, so they say nothing about what the insider thinks today. Block has no open-market purchase (code P) in the history, the most common case in the S&P 500: insiders are already paid in stock. The latest filing is from Oct 19, 2026, and a Form 4 arrives up to two business days after the trade.
20 of the 20 rows in the table carry footnotes from the Form 4 itself, folded into the code column and copied verbatim; a row with no footnote means the filing has none.
