Citigroup Expands Rivian Stake to Post-IPO High as EV Maker’s Shares Climb

Citigroup has aggressively increased its position in Rivian Automotive, more than doubling its stake in the electric vehicle manufacturer during Q3 2025. SEC filings reveal the bank acquired 4.95 million additional shares, elevating its total holdings to 8.54 million shares valued at approximately $125 million. This represents Citi's largest position since Rivian's 2021 market debut.

The MOVE follows a pattern of growing institutional confidence, with Citigroup having doubled its Rivian exposure in both Q2 and Q3 this year. Rivian shares responded positively to the disclosure, gaining over 7% in Tuesday's session. The bank's evolving position mirrors Wall Street's broader reassessment of EV players amid shifting market dynamics.

While maintaining Nvidia as its top portfolio holding, Citigroup's $147 billion investment portfolio now reflects stronger conviction in Rivian's long-term trajectory. The bank's initial 2021 investment of 76,738 shares has grown exponentially, weathering periods of volatility in the EV sector.
