TuSimple has raised $648 million across multiple funding rounds to advance Level 4 autonomous trucking solutions. Key backers include Volkswagen Group, HTIF, Sina, UPS, and Navistar. The company secured $15 million in post-IPO funding in August 2022, led by Rubric Capital, following earlier undisclosed Series E rounds in 2021 that involved Goodyear Ventures, Werner Enterprises, and U.S. Xpress. With its proprietary autonomous operations system, high-speed perception stack, and long-haul freight automation capabilities, TuSimple is one of the most highly funded players in the autonomous trucking sector.
