UPST — Insider Trading Activity

UPST is not showing a cluster buy or a step-change versus its own baseline, so what the window amounts to is a single insider acting alone. Who is buying. The most credible buyer in this window is the company’s CEO ($1M–$5M), growing their stake by 6%. That insider’s track record: past buys beat the S&P 500 0 of 1 time (avg −37% vs S&P over 6 mo). Overall credibility score: 54/100 (Medium).

By the numbers. One insider filed 1 open-market purchase at UPST over the window, 50,000 shares in all at an average of $25.55 a share, most recently on September 10, 2026. On the other side, 4 insiders filed 10 sales covering 157,162 shares at an average of $27.83, the latest on September 8, 2026. That puts the average sale 9% above the average purchase — worth checking against where the stock trades today.

How we read these filings — which transaction codes count, how the cluster and credibility thresholds are set, and what the signals have and haven’t predicted — is written up in the insider trading methodology.
