Rivian $RIVN falls 10% on 75M-share offering after 8.1% rally

Rivian Automotive $RIVN fell about 10% after the EV maker launched an underwritten public offering of 75,000,000 common shares, a capital raise large enough to reverse the stock’s 8.1% Monday gain and much of the 19.2% advance from the prior week. The move meets the finance-crawler Tier-1 threshold because the single-stock reaction exceeded 8% and was tied to a concrete financing event.

The company’s offering announcement says all shares are being sold by Rivian. It also gives the banks a 30-day option to buy up to 11,250,000 additional shares at the public offering price, less underwriting discounts and commissions. If that option is fully used, the offering would cover 86.25 million shares before expenses.

CNBC’s feed timestamped the story at 2026-07-07T12:50:55Z, inside the 48-hour window, and reported the roughly 10% stock decline. The market reaction was focused less on the mechanics of the deal than on dilution: a large new-share sale changes per-share ownership at a time when investors are still measuring Rivian’s cash runway, R2 launch spending, and path to scale.

The next datapoint is the final offering size and price. After that, investors will compare the new cash raised with the company’s second-quarter delivery update, expected operating losses, and any updated capital-spending language in the next earnings release. The financing itself is not a buy or sell signal; the market move shows how sensitive the equity remains to balance-sheet funding.
