NEW YORK, December 31, 2025, 06:05 ET — Premarket
- Rivian shares were down about 0.9% in premarket trading after a 5.2% slide in the prior session.
- A regulatory filing showed CEO R.J. Scaringe sold 17,450 shares under a pre-arranged trading plan.
- Traders are watching Tesla’s delivery report and Rivian’s quarter-end production and delivery update for demand signals.
Rivian Automotive shares were down about 0.9% in premarket trading on Wednesday at $19.42, after the stock fell 5.2% in the previous session. 1
The decline has kept focus on an insider-trading disclosure that surfaced as markets moved into the year’s final, lower-liquidity stretch, when smaller orders can move prices more than usual.
That matters now because Rivian’s stock has been a high-volatility trade, and investors are sensitive to signals around funding risk and demand trends across the electric-vehicle sector.
Insider sales can weigh on sentiment because some investors interpret them as a confidence signal, even when the transactions were scheduled in advance and are not tied to fresh company developments.
A Form 4 filing showed Chief Executive Officer R.J. Scaringe sold 17,450 shares on Dec. 23 at a weighted average price of $21.4253 in transactions ranging from $21.21 to $21.69, and said the sale was made under a Rule 10b5-1 plan, a pre-arranged trading program that sets trades ahead of time. https://www.sec.gov/Archives/edgar/data/1874178/000187417825000102/wk-form4_1734999771.xml
Rule 10b5-1 plans are designed to reduce concerns that executives are trading based on material nonpublic information, but the headline “insider sale” can still pressure crowded trades.
Rivian’s slide has also come as investors look for near-term reads on EV demand. Tesla is expected to report lower fourth-quarter deliveries on Friday, after the loss of U.S. tax credits and heavier competition, Reuters reported. https://www.reuters.com/business/autos-transportation/tesla-quarterly-deliveries-seen-falling-lack-tax-credits-competition-sap-demand-2025-12-30/
Broader markets have been prone to abrupt rotations in holiday-thin trade. “It’s just a healthy rebalancing of allocations,” Mark Hackett, chief market strategist at Nationwide, said in a Reuters report on Tuesday’s session. https://www.reuters.com/business/us-stock-futures-stabilize-after-tech-led-dip-halts-year-end-rally-2025-12-30/
For Rivian, investors have kept the spotlight on cash burn — how quickly the company spends cash to fund operations — and whether production efficiency and higher-margin software revenue can narrow losses.
The next company-specific checkpoint is Rivian’s quarterly production and delivery update, which the company has historically released shortly after the quarter ends, alongside timing for its results call. 2
On the chart, traders have been watching whether the shares can hold above Tuesday’s intraday low near $19.28 after opening around $20.68, levels that often become near-term support and resistance. 3
