Rivian (RIVN) has kicked off an underwritten public offering of 75 million shares of common stock, targeting proceeds of roughly $1.5 billion at the stock's recent price. The capital raise comes hot on the heels of a surge in the company's share price, which jumped after it reported stronger-than-expected second-quarter delivery numbers and raised its full-year outlook.

The funds are earmarked for Rivian's R2 vehicle program, a more affordable, mid-size SUV that the company hopes will broaden its market reach beyond the premium R1T pickup and R1S SUV. The R2 is central to the automaker's strategy to scale production and achieve cost efficiencies, as it targets a lower price point to compete with Tesla's Model Y and other mainstream EVs.

This is Rivian's first major equity raise since it went public in 2021, and it reflects both the capital-intensive nature of EV manufacturing and the company's ambitious production ramp. Rivian ended the second quarter with about $9 billion in cash and equivalents, but the R2 launch — expected in early 2026 — will require significant investment in its Normal, Illinois plant and supplier network.

The timing is strategic: by tapping public markets while its stock is buoyed by positive delivery news, Rivian is locking in better terms than it might have a month ago, when shares were trading lower. However, this also dilutes existing shareholders, a move that typically weighs on stock price in the near term.
