Insiders at Snowflake Inc. (SNOW) have been selling. Over the trailing 180 days through October 7th, 2026, the open-market ledger shows sales on one side and nothing on the other. The net figure is negative $973,538,529.
The ledger breaks down this way: 216 sell filings from 9 distinct insiders, against no open-market purchase filings in the same window. The dollar value on the sell side was $973.5 million. The dollar value on the buy side was zero, so the net reads as straight net selling rather than a mix that happened to tilt one way.
Snowflake Inc. operates in the Services-Prepackaged Software sector. A selling pattern this concentrated in filings count is worth separating from the dollar total, because a large number of filings from a small number of people often reflects staged dispositions rather than a single decision made on a single day.
The largest seller was Frank Slootman, a Director, at $636,478,078 across the window. That is the majority of the total sold by all 9 insiders combined. There was no largest buyer to name, because no insider recorded an open-market purchase during the 180 days reviewed.
On the price side, the last price in our table is $368.89, which corresponds to a market capitalization of $130,144,395,264. We are not quoting a percentage move over the window here, because that figure is not part of the reconciled ledger behind this article. The sales should be read against the size of the company rather than in isolation.
What the ledger does not say matters as much as what it does. Only Form 4 codes P and S are counted here, which means awards, tax withholding and option exercises are excluded. Those events move shares around an insider's account without being a decision to buy or sell at a market price, and including them tends to inflate both sides of a count.
A sale also carries less signal than a purchase as a general matter. Executives and directors receive much of their compensation in stock, and selling is the ordinary way that compensation becomes cash. Many sales are executed under a Rule 10b5-1 plan adopted months before the trade date, which removes the insider's discretion over timing. The Form 4 record does not tell you which of these sales were plan trades and which were not, and nothing in the filings explains why any individual chose to sell.
What the record does establish is the direction and the scale. Nine insiders sold, none bought on the open market, and the total reached $973.5 million over six months, with a single Director responsible for $636,478,078 of it. Readers tracking Snowflake Inc. can weigh that against the company's $130,144,395,264 market value and the $368.89 last price, and against whatever disclosure the company has made about trading plans.
