Block, Inc.
One of the world's largest fintech companies, Block runs two big ecosystems: Square, which helps small businesses take card payments with its little white card reader, and Cash App, a popular money app, plus brands like Afterpay and TIDAL. It was founded in 2009 when glassblower Jim McKelvey lost a sale because he couldn't accept credit cards, so he and Twitter's Jack Dorsey built a square-shaped reader. Fun fact: the company was briefly called "Squirrel" before settling on Square, and later renamed itself Block after blockchain.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over all recorded history: -32.90M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
