Yesterday was the deadline for institutions to fill 13-F forms about their shenanigans in Q1 to SEC (Shortseller Enrichment Commission). What was a mystery is now revealed and is available for public scrutiny. Here are the most important changes in Rivian ownership this Q1:

• Rivian issued 82.4M new shares — 62.9M to Volkswagen Group and 19.6M to Uber (8-K Item 3.02).
• In Q1 2026, institutional investors net-reduced their RIVN position by 53.4M shares (26.3M bought across 37 managers, 79.7M sold across 53)
• 18 Institutional Investors have sold 100% of their RIVN shares - mostly hedge funds and foreign banks.

The most noticeable names, who built their positions in 2025 and heavily dumped their RIVN shares this Q1 (potentially unloaded in January to retail investors) are Two Sigma Advisers & Investments (a hedge fund that sold 24.4M shares) and Renaissance Technologies by Jim Simmons - unloaded another 5.5M shares. Closely followed by D.E Shaw, Norges Bank and some others.
