This profile gathers the share dealings of ARCH Venture Partners X, LLC across 5 companies, led by Neumora Therapeutics, Inc., Prime Medicine, Inc. and Sienna Biopharmaceuticals, Inc. Over a trading history stretching from 22 February 2019 to 27 October 2025, the count stands at 28 filings.
No open-market sale appears; the market trades are 10 purchases worth €98.0M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Since January 2025: 2 purchases and no sales on the market.

The record was last updated on 29 October 2025 with an open-market purchase (€4.3M) in Neumora Therapeutics, Inc. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. US insiders must file a Form 4 within two business days of a trade. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
