CEO & Board Co-Chair · Cloudflare, Inc. (NET)
This is the public record of open-market stock transactions Matthew Prince has reported to the SEC on Form 4 as CEO & Board Co-Chair of Cloudflare, Inc. (NET). Every figure below is the reported share count multiplied by the reported price, so the dollar amounts are exact disclosed values rather than estimates. It is a record of what has been filed, not a portfolio or a recommendation, and insider selling in particular is routine and rarely a signal on its own.
Most of Matthew Prince's sales were pre-scheduled or tax-related rather than discretionary, which further weakens any read of them as a market call.
All 19 disclosed transactions, newest filing first.
How many shares has Matthew Prince bought and sold?
Matthew Prince has disclosed 19 Form 4 transactions in the record we track, from Aug 18, 2025 to Aug 5, 2026: 19 sales worth $439,059,149 and no open-market purchases. Each figure is the reported share count multiplied by the reported price, so these are exact disclosed amounts, not estimates.
Is Matthew Prince selling a bearish signal?
Not on its own. Insiders sell for many reasons that have nothing to do with a view on the stock — diversification, taxes, estate planning, or a pre-scheduled plan set up months earlier. Of the 19 sales on this record, 19 were made under a Rule 10b5-1 plan and 0 were automatic tax withholding on vesting shares, leaving 0 that were the insider's own discretionary decision (worth $0). Buying is the cleaner signal, because there is only one reason to buy. This page is a record, not a recommendation.
