AI Export Reversal: How the Rescission of the Diffusion Rule Could Shift Tech Markets

The Trump administration’s abrupt decision to rescind the Biden-era AI Diffusion Rule has sent shockwaves through global tech markets, reshaping the calculus for U.S. semiconductor giants and their international competitors. The May 7 announcement, which aims to replace a tiered export control framework with a “simpler rule,” could redefine the competitive landscape for AI infrastructure and unlock new opportunities—or risks—for investors.

Ask Aime: What impact will the AI Diffusion Rule's rescind have on U.S. semiconductor companies?

The Event: A Pivot in U.S. Tech Policy

On May 7, 2025, the U.S. Department of Commerce confirmed plans to rescind the AI Diffusion Rule, a Biden-era policy designed to curb China’s access to advanced AI chips and model weights. The rule, set to take effect on May 15, had divided countries into three tiers: allies (Tier 1), partners requiring licenses (Tier 2), and restricted nations like China (Tier 3). Critics, including tech giants like Nvidia and AMD, argued the system was overly complex, stifling innovation and market access.

The administration’s reversal, framed as a move to “unleash American AI dominance,” reflects a strategic shift toward deregulation. As Nvidia CEO Jensen Huang noted, being locked out of China’s booming AI market would be a “tremendous loss,” a sentiment echoed by investors who sent Nvidia’s stock up 3% on the news.

The Case for Deregulation

Proponents of the rescission argue that the old framework’s bureaucratic hurdles were strangling U.S. competitiveness. The Biden-era rules required companies to navigate tiered export controls, comply with “Total Processing Performance (TPP) allocations,” and secure licenses for shipments to certain countries. For instance, exporting advanced AI chips to China—a market valued at $18 billion in 2024—would have been nearly impossible under Tier 3 restrictions.

The Trump administration’s simplified approach aims to eliminate these barriers, potentially boosting revenue for U.S. chipmakers. “This isn’t just about China—it’s about ensuring American companies can compete globally without overregulation,” said a Commerce Department spokesperson.

The Risks of Rolling Back Controls

Opponents, including national security experts, warn that easing restrictions could accelerate China’s AI capabilities. The original rule targeted not just chips but also “model weights” of advanced AI systems, requiring licenses for exports of models trained on ≥10²⁶ computational operations. Without these controls, Beijing could access technologies that narrow the U.S. lead in AI.

Former Biden officials also note that the tiered system was designed to balance security and commerce. As one advisor noted, “The TPP allocation framework was a deliberate compromise—it’s unclear how the new rule will prevent tech leaks.”

The Investment Play: Positioning for the New Landscape

The rescission creates both opportunities and uncertainties for investors.

1. Short-Term Gains for Semiconductor Stocks:
2. Nvidia, AMD, Intel: Companies with global exposure to AI infrastructure stand to benefit immediately. The removal of export barriers could unlock billions in revenue from markets like China and Southeast Asia.

3. Data Point: Analysts at Goldman Sachs estimate that easing restrictions could add 8-12% to Nvidia’s annual revenue by 2027.

4. Long-Term Risks of Overexposure:

5. Geopolitical Volatility: U.S.-China tensions could reignite if Beijing perceives the policy shift as a sign of U.S. weakness, prompting retaliatory measures.
6. Security Concerns: Without controls on model weights, the diffusion of frontier AI technologies might attract scrutiny from regulators or investors worried about ethical misuse.

Conclusion: A New Era of Tech Diplomacy

The rescission of the AI Diffusion Rule marks a pivotal moment for investors. While the immediate boost to semiconductor stocks is clear—Nvidia’s 3% jump on May 7 underscores this—the long-term implications hinge on how the U.S. balances innovation with security.

Investors should prioritize companies with diversified revenue streams, strong R&D pipelines, and exposure to high-growth markets. For instance, AMD’s partnerships with cloud providers like Alibaba (which could now more easily access U.S. chips) position it to capitalize on deregulation. Meanwhile, firms like Intel, which faces stiff competition from Chinese rivals like Semiconductor Manufacturing International Corporation (SMIC), must prove their value in a less restricted environment.

The policy shift also signals a broader trend: the U.S. is recalibrating its approach to tech leadership, favoring economic growth over containment. As one analyst noted, “This isn’t just about chips—it’s about who writes the rules of the next tech revolution.” For investors, staying ahead of those rules will be key to success.
