Two Volkswagen Engineers Face Federal Charges Over Rivian Trade

The Allegation

Michael Stamp and Marcus Plank, both engineers at Volkswagen's San Jose operations, now face up to 25 years in federal prison after prosecutors accused them of securities fraud tied to the German automaker's electric vehicle partnership with Rivian. The indictment, unsealed by the U.S. District Attorney for the Southern District of New York, claims the two men generated more than $300,000 in profits by purchasing Rivian stock and options ahead of a public announcement that would send the EV maker's share price climbing.

The case centers on what Volkswagen and Rivian internally called "Project Climb," a collaboration focused on electric vehicle architecture and software that was announced publicly in June 2024. According to prosecutors, Stamp and Plank learned of the pending deal through their work at Volkswagen and made trades before the information reached the broader market. When the partnership was revealed, Rivian's stock jumped 23% in a single session. The two engineers then allegedly liquidated their positions, with Stamp realizing approximately $250,000 in gains and Plank about $50,000. A close family member of Plank also made roughly $12,000, according to the indictment.

Evidence of Intent

What makes this case particularly striking is the digital trail prosecutors say the defendants left behind. Eight days before the joint venture became public, Stamp allegedly searched online for "statute of limitations insider trading." Around the same time, a close family member of Plank searched in German for information on how insider trading is prosecuted. These searches, detailed in court filings, suggest the individuals understood the legal boundaries they were crossing.

At DailyTechWire, we've tracked a steady uptick in enforcement actions targeting employees at tech and automotive companies as cross-industry partnerships proliferate. The overlap between hardware, software, and mobility has created new information asymmetries, and regulators are signaling they will pursue cases even when the trades involve relatively modest sums compared to Wall Street standards.

The Deal That Triggered It All

Volkswagen announced the Rivian joint venture with an initial commitment of $5 billion, structured as milestone-based capital releases. The partnership has since expanded to $5.8 billion, making Volkswagen the largest shareholder in Rivian. For the German automaker, the deal represented a strategic bet on Rivian's software and electrical architecture capabilities, areas where legacy manufacturers have struggled to match the pace of EV-native startups. For Rivian, the capital injection provided a lifeline at a time when the company was burning cash to ramp production of its R1T pickup and R1S SUV.

The timing of the announcement was critical. Rivian had been under pressure from investors to demonstrate a path to profitability, and Volkswagen was racing to electrify its lineup amid tightening emissions standards in Europe and China. The partnership allowed both companies to share development costs while maintaining separate brands and go-to-market strategies.

Market Integrity and Enforcement

U.S. Attorney Jay Clayton emphasized that the alleged conduct undermines the fairness that allows capital markets to function efficiently. Insider trading cases hinge on the principle that material, non-public information belongs to shareholders, not individual employees. When insiders trade on that information, they effectively steal value from other market participants who lack the same knowledge.

The prosecution's statement made clear that enforcement priorities extend beyond high-profile hedge fund managers or corporate executives. Engineers and mid-level employees with access to sensitive deal information are equally subject to securities laws. The case also illustrates how international collaborations, particularly in the automotive and technology sectors, create compliance challenges. Employees working on cross-border projects may have access to market-moving information months before it becomes public, and companies must implement rigorous controls to prevent leaks and trading violations.

What Happens Next

Both Stamp and Plank were arrested and are expected to appear in the U.S. District Court for the Northern District of California. The case has been assigned to U.S. District Judge Katherine Polk Failla. If convicted, each defendant could face up to 25 years in prison, though actual sentences in securities fraud cases often fall well short of statutory maximums, depending on the amount of ill-gotten gains and cooperation with authorities.

Volkswagen issued a brief statement acknowledging the charges and noting that the action is focused on individuals rather than the company itself. Rivian declined to comment. Neither company has been accused of wrongdoing, and there is no indication that either was aware of the alleged trading activity before law enforcement intervened.

Broader Implications for Automotive Tech

This indictment arrives at a moment when automotive and technology companies are forging an unprecedented number of partnerships. Joint ventures, licensing deals, and co-development agreements have become the dominant strategy for spreading the cost and risk of electrification and autonomous driving. But each new collaboration creates a wider circle of employees who gain early visibility into market-sensitive information.

The Volkswagen-Rivian case may prompt companies to tighten access controls around deal teams, implement more aggressive monitoring of employee trading activity, and expand pre-clearance requirements for stock purchases. Some firms already require employees to report all personal securities transactions and obtain approval before buying or selling shares in competitors, partners, or suppliers. Others use automated systems to flag unusual trading patterns in the days before major announcements.

For engineers and other technical staff, the message is unambiguous: access to confidential project information does not confer a right to trade on it. The legal standard for insider trading does not require a formal executive title or a seat in the boardroom. Anyone who possesses material, non-public information and owes a duty to their employer or its shareholders can be prosecuted if they trade on that knowledge or tip others.

The outcome of this case will be closely watched across Silicon Valley, Detroit, and Stuttgart. As the lines between automotive manufacturing, software development, and financial engineering continue to blur, the risk of insider trading will only grow. Companies that fail to educate employees and enforce strict compliance protocols may find themselves facing not only individual prosecutions but also civil penalties and reputational damage that can complicate future partnerships.
