TuSimple builds self-driving technology for long-haul semi trucks, using cameras and computer vision so big rigs can pilot themselves on highways and freight routes. Founded in 2015 by Xiaodi Hou and Mo Chen, it was headquartered in San Diego with deep roots in China, and in 2021 it completed the world's first fully autonomous truck run on open public roads with no one in the cab, traveling from Tucson to Phoenix, Arizona. The name is a playful double meaning: it draws on the Chinese character for "image" while also joking that the challenge was "too simple."
Select a row to see that insider’s individual transactions. † Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 5 years: -637.1K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
