Benjamin Silbermann has filed 128 Form 4 transactions, all in a single company, Pinterest (PINS). The pattern is one-directional. His total sell value is $77,375,312.03, while his total buy value is zero. He has acquired $269,982.84 in shares, but that figure comes from grants or awards, not open-market purchases. The code legend is explicit: only an open-market purchase, code P, shows conviction. Silbermann has not filed a single P transaction.
The recent activity is a steady stream of open-market sales, code S, paired with conversions, code C, which carry a value of zero. Between September 9 and October 21, 2026, he sold on 13 separate days. The sales are consistent in size, ranging from $853,453.13 on September 23 to $1,075,350 on October 21. The cadence is roughly weekly, sometimes with two sales in consecutive days, as seen on September 22 and 23, and again on October 20 and 21. Each sale is paired with a conversion of a derivative security, which suggests a mechanical process of converting and then selling.
The dollar values trend upward over the period. The September 9 sale was $939,487.50. The October 21 sale was $1,075,350. The total for the 13 recent sales is roughly $12.3 million. There is no countervailing buying. The data shows a seller who is methodically reducing his position in PINS through repeated open-market sales, with no purchases to offset the outflow.
