Tariff Ruling Reshapes Trade Landscape, NVIDIA Fuels AI Optimism

This week, financial markets experienced significant positive momentum driven by two pivotal developments: a landmark U.S. court ruling that blocked President Trump’s sweeping tariffs, and NVIDIA’s robust first-quarter fiscal 2026 earnings report. The court’s decision to curb executive authority on trade policy was met with broad relief, easing concerns over inflation and global trade uncertainty. Concurrently, NVIDIA’s exceptional performance, particularly in its Data Center segment, underscored the accelerating demand for Artificial Intelligence (AI) infrastructure, reinforcing the bullish narrative for the technology sector. These dual tailwinds have collectively boosted investor confidence and risk appetite, setting a more optimistic tone for the near term, though the long-term implications of the tariff ruling’s appeal and ongoing geopolitical tech competition warrant continued monitoring.

The U.S. Court of International Trade delivered a significant blow to President Trump’s trade policy this week, ruling against his administration’s broad-based tariffs. This decision, issued by a three-judge panel, has far-reaching implications for global trade and executive power.

On Wednesday, May 28, 2025, the New York-based U.S. Court of International Trade issued a unanimous ruling blocking President Donald Trump from imposing sweeping tariffs under the International Emergency Economic Powers Act (IEEPA) of 1977. The court found that Trump’s “Liberation Day” tariffs and other levies, including those recently imposed on China, Mexico, and Canada in response to perceived threats like drug and illegal immigrant flows, exceeded his authority. 

The core of the ruling asserted that the IEEPA does not grant the President unilateral authority to impose tariffs as a means to address trade deficits or other broad economic issues. The court explicitly stated that such actions are “impermissible not because it is unwise or ineffective, but because [federal law] does not allow it”. This determination underscored the judicial branch’s role in delineating the boundaries of executive authority. The court emphasized that the U.S. Constitution grants Congress exclusive power to regulate commerce with other nations, a power not superseded by the President’s emergency remit to safeguard the economy. The long-standing nature of U.S. trade deficits, which have persisted for 49 consecutive years, was cited as evidence that the situation does not constitute a “sudden emergency” justifying such sweeping measures under IEEPA. This ruling represents a significant judicial check on the executive branch’s power, particularly in areas traditionally reserved for the legislature. It establishes a precedent that could limit future administrations’ ability to unilaterally impose broad economic measures under emergency declarations without clear statutory authorization or direct Congressional approval. For market participants, this suggests a potential return to more predictable, legislatively-driven trade policy, reducing the uncertainty previously stemming from executive discretion. 

The White House, through spokesperson Kush Desai, immediately lodged an appeal, asserting that trade deficits constitute a national emergency and that it is “not for unelected judges to decide how to properly address a national emergency”. The administration remains committed to using executive power to address what it perceives as a crisis. The court gave the administration 10 days to “effectuate” the order, though it did not specify how the tariffs should be unwound. 

The court’s decision specifically blocks the broad-based tariffs Trump imposed on “almost all U.S. trading partners,” including the so-called reciprocal tariffs (up to 50%) and the 10% baseline tariffs. It also explicitly blocked levies on China, Mexico, and Canada that were justified under the IEEPA. This means a wide array of goods from numerous countries are now theoretically exempt from these particular duties. 

Crucially, the ruling does not affect other Trump tariffs, such as the 25% taxes on imported steel, aluminum, and autos. These were imposed under Section 232 of the Trade Expansion Act of 1962, which requires a Commerce Department investigation into national security risks. These tariffs operate under a different legal statute and are not subject to the President’s sole discretion in the same manner as those invoked under IEEPA. While the ruling blocks the sweeping, broad-based tariffs, the continued presence of targeted tariffs on specific industries implies that the administration loses its immediate leverage for imposing across-the-board duties to extract concessions from trading partners. Future trade negotiations may necessitate a slower, more deliberate approach, potentially relying on different statutory authorities or more traditional diplomatic channels. For businesses, this translates to a reduction in systemic trade uncertainty but continued, albeit more predictable, risks in specific sectors still covered by unaffected tariffs. 

Financial markets largely welcomed the court’s decision. U.S. stock futures jumped early Thursday, with S&P 500 futures gaining 1.7%, Dow Jones Industrial Average futures up 1.4%, and Nasdaq futures climbing nearly 2%. Global equities also saw gains, with Japan’s Nikkei 225 jumping 1.9%, Hong Kong’s Hang Seng adding 1%, Shanghai Composite gaining 0.8%, and South Korea’s Kospi surging 1.8%. The U.S. dollar strengthened against safe-haven currencies like the Japanese yen and euro, and oil prices rose more than $1, indicating a boost in risk appetite. 

Analyst Stephen Innes of SPI Asset Management noted that investors were “exhaling after weeks of white-knuckle volatility sparked by trade war brinkmanship,” suggesting the ruling brings “a fresh dose of macro stability”. This immediate positive reaction underscores the market’s strong preference for predictability and reduced trade friction. 

Economically, the blocking of these tariffs is expected to mitigate risks of higher prices and recession that the tariffs had previously introduced. The Federal Reserve had been holding off on interest rate cuts due to concerns about inflation staying higher than hoped because of these sweeping tariffs. The court’s ruling, by blocking these tariffs, removes a significant source of upward pressure on consumer prices. This reduction in inflationary risk could provide the Federal Reserve with greater flexibility in its monetary policy, potentially opening the door for interest rate adjustments that could further stimulate economic growth. The positive market reaction, including rising futures and oil prices, reflects this anticipated easing of economic headwinds. 

While the immediate market reaction was positive, characterized by investors “exhaling” , the White House’s immediate appeal  introduces a layer of persistent uncertainty. Analysts describe the ruling as a “brief respite before the next thunderclap”  and note that the administration might employ “other substitute acts” to maintain tariffs. This indicates that the fundamental trade policy dispute is not definitively resolved but has merely shifted to a protracted legal battle and potential executive workarounds. Market participants should be aware that while the immediate pressure is relieved, the specter of renewed trade tensions remains, requiring vigilance. 

NVIDIA (NVDA) delivered another stellar earnings report for its first quarter of fiscal year 2026, further solidifying its position at the forefront of the artificial intelligence revolution. The results, announced after market close on Wednesday, May 28, 2025, largely surpassed analyst expectations, despite ongoing challenges from U.S. export controls.

NVIDIA reported Q1 FY26 revenue of $44.1 billion, a remarkable 69% increase year-over-year and 12% quarter-over-quarter. This figure comfortably exceeded analyst estimates of approximately $43.28 billion. The Data Center segment, the primary driver of NVIDIA’s AI-related revenue, saw its revenue surge to $39.1 billion, representing a 73% increase from a year ago and 10% from the previous quarter. This performance was a key highlight, demonstrating “feverish demand for its high-powered chips”. 

Non-GAAP diluted earnings per share (EPS) came in at $0.81. Notably, excluding a $4.5 billion charge related to H20 export controls, non-GAAP diluted EPS would have been $0.96, significantly above analyst expectations of $0.73 or $0.93. Gross margins were 61.0% non-GAAP, which, excluding the H20 charge, would have been 71.3%. Despite facing “tariff-driven turbulence”  and incurring a substantial $4.5 billion charge due to “export control limitations” on H20 chips , NVIDIA still managed to deliver “robust growth” and exceed projections. This performance strongly indicates that the fundamental, global demand for AI infrastructure is so overwhelming that it currently overshadows the negative impacts of geopolitical restrictions. For investors, this reinforces the view that NVIDIA’s core business is exceptionally strong, and while China restrictions are a headwind, they are not derailing the company’s overall growth trajectory. 

NVIDIA disclosed a $4.5 billion charge in Q1 FY26 due to excess H20 inventory and purchase obligations, as demand for these chips diminished following new U.S. export licensing requirements. The company was also unable to ship an additional $2.5 billion of H20 revenue in Q1. Looking ahead, NVIDIA’s outlook for Q2 FY26 reflects an estimated $8.0 billion loss in H20 revenue due to these export control limitations. 

CEO Jensen Huang expressed regret over the U.S. government effectively blocking AI chip sales to China, a market he estimated at $50 billion. He warned that these export controls are spurring China to accelerate its own chip development, a shift he predicts the U.S. will eventually regret, as it “strengthens them abroad and weakens America’s position”. NVIDIA is actively mitigating these impacts, with Huang noting that Middle East deals are expected to help fill the $8 billion revenue gap left by the loss of Chinese business. The company also aims to achieve gross margins in the mid-70% range later this year. NVIDIA’s actions and commentary reveal a proactive strategy to adapt to geopolitical challenges. The company is not merely absorbing the impact of export controls but is actively repurposing parts of the H20 chips  and aggressively pursuing new markets, such as the Middle East, to offset lost revenue. CEO Huang’s public criticism of the export curbs suggests a strategic effort to influence policy by highlighting the long-term competitive risks for the U.S. This demonstrates a resilient management team capable of navigating complex global dynamics, providing a degree of reassurance to investors about the company’s ability to sustain growth despite external pressures. 

Jensen Huang reiterated that “Global demand for NVIDIA’s AI infrastructure is incredibly strong”. He highlighted that “AI inference token generation has surged tenfold in just one year,” and he anticipates that “as AI agents become mainstream, the demand for AI computing will accelerate”. Huang emphasized the global recognition of AI as “essential infrastructure — just like electricity and the internet” , positioning NVIDIA “at the center of this profound transformation”. 

For Q2 FY26, NVIDIA expects revenue of $45.0 billion, plus or minus 2%. While this outlook slightly missed some analyst projections (e.g., $45.9 billion by FactSet), it still represents robust sequential growth. The company is also focused on improving profitability, forecasting GAAP and non-GAAP gross margins of 71.8% and 72.0% respectively for Q2, with a goal of reaching the mid-70% range later in the year. Recent highlights include the full-scale production of the Blackwell NVL72 AI supercomputer, the availability of Blackwell cloud instances on major platforms like AWS, Google Cloud, Microsoft Azure, and Oracle Cloud Infrastructure, and record-setting performance in MLPerf inference results. NVIDIA is also actively building AI factories in the U.S. and partnering globally. CEO Huang’s consistent message about “incredibly strong” global demand  and the accelerating need for AI computing, coupled with the impressive Data Center revenue growth , signifies that the AI boom is not merely a transient trend. The widespread adoption of Blackwell instances across major cloud providers  and the strategic partnerships to build AI factories globally  indicate a fundamental, multi-year infrastructure build-out phase. This suggests a durable growth trajectory for NVIDIA, driven by the foundational shift of AI becoming “essential infrastructure”  for enterprises and nations alike. 

NVIDIA’s shares reacted strongly to the earnings report, jumping nearly 5% in after-hours trading. This performance positioned NVIDIA to potentially surpass Microsoft as the world’s most valuable company by market capitalization. The positive results from NVIDIA “rejuvenated investor optimism across the board,” particularly for the broader technology and AI sectors. Wedbush Securities analyst Dan Ives noted that “This is a very important print and guide for the broader tech world and it shows the AI revolution is heading into its next gear of growth despite the Trump tariff war playing out”. NVIDIA’s outlook also positively impacted other chip stocks and suppliers in Asia, including Advantest Corp., SK Hynix Inc., and Foxconn Industrial. NVIDIA is consistently referred to as an “artificial intelligence technology bellwether”. Its earnings report is not just about the company itself but serves as a crucial indicator for the entire AI industry and, by extension, the broader technology market. The strong performance, despite external challenges, validates the significant investments being made by major tech companies in AI  and confirms that the “AI boom is still going strong”. Understanding NVIDIA’s results provides a valuable lens through which to assess the health and future trajectory of the rapidly expanding AI economy. 

The simultaneous emergence of a favorable court ruling on tariffs and NVIDIA’s stellar earnings report created a powerful confluence of positive sentiment in the markets, signaling a renewed appetite for risk and growth.

U.S. stock futures surged higher on Thursday, directly boosted by the federal court’s decision to block most of President Trump’s “reciprocal” tariffs and the “healthy earnings from artificial intelligence heavyweight Nvidia”. This dual positive impetus “sparked euphoria in Asia-Pacific markets” , leading to broad gains across indices. Analysts underscored this combined effect, with FXStreet noting that “Nvidia, tariff ruling fuel optimism”. Wedbush analyst Daniel Ives explicitly linked the two, stating that NVIDIA’s robust performance, despite the “Trump tariff war playing out,” confirms that “the AI revolution is heading into its next gear of growth”. This suggests that the market is finding strong fundamental drivers (AI) even as macroeconomic uncertainties (tariffs) begin to recede. The simultaneous positive news from both a macro policy perspective (tariff relief) and a micro corporate performance perspective (NVIDIA’s AI-driven growth) has created a potent “risk-on” environment. The reduction in trade uncertainty and potential inflationary pressures from the tariff ruling, combined with the validation of the robust AI growth narrative by NVIDIA, encourages investors to re-allocate capital towards growth-oriented assets. This is evidenced by the broad market gains, including rising futures and oil prices, reflecting increased investor confidence and a willingness to embrace risk. 

While the initial market reaction was positive, several forward-looking considerations warrant attention:

• Tariff Ruling Appeal: The White House has already appealed the court’s decision. The long-term outcome of these legal disputes remains uncertain, with the case potentially heading to the Supreme Court. Furthermore, analysts suggest the Trump administration might explore “other substitute acts” to impose tariffs, meaning the threat of trade protectionism is not entirely removed. This ongoing legal and political uncertainty could reintroduce volatility and requires continued monitoring. 
• AI Market Momentum and Competition: NVIDIA’s outlook for Q2 FY26 remains strong, with expected revenue of $45.0 billion, signaling sustained demand for AI infrastructure. The company’s continued innovation with Blackwell and expansion of cloud partnerships reinforce its leadership. However, CEO Huang’s concerns about U.S. export controls spurring China to develop its own chips and potentially strengthening foreign competitors highlight an evolving competitive landscape and geopolitical risks that could impact long-term market share. 
• Monetary Policy Implications: The Federal Reserve has maintained a cautious stance on interest rates, partly due to inflation concerns exacerbated by tariffs. While the tariff ruling could ease some of these inflationary pressures, the Fed is unlikely to make immediate policy changes, with current market expectations not suggesting a rate cut before September. The Fed will likely continue to monitor economic data and the ultimate resolution of the tariff situation before adjusting its stance. 

The current market optimism is a direct result of a positive shift in macroeconomic policy (the tariff ruling) coinciding with strong performance in a key innovation sector (AI, led by NVIDIA). This highlights how both governmental actions and technological advancements are critical, interconnected drivers of market sentiment. However, the future trajectory of the market will depend on the continued interplay of these forces. The unresolved legal battle over tariffs means policy uncertainty could resurface, while the burgeoning AI market faces its own challenges, including intensifying competition and the long-term effects of export controls. Market participants must appreciate that sustained positive momentum requires stability on both policy and innovation fronts.

The past week has delivered a powerful one-two punch of positive news for the stock market. The U.S. Court of International Trade’s decision to block President Trump’s sweeping tariffs offers a significant reprieve from trade uncertainty and potential inflationary pressures, fostering a sense of relief across global markets. Simultaneously, NVIDIA’s exceptional Q1 FY26 earnings underscore the relentless and accelerating demand for AI infrastructure, solidifying the company’s pivotal role in this transformative technological era.

While these developments have collectively fueled investor optimism and a “risk-on” sentiment, it is crucial for market participants to remain discerning. The tariff ruling’s appeal process means that the trade policy landscape is not yet fully settled, and the potential for renewed tensions or alternative executive actions remains. Similarly, while AI demand is robust, the long-term impact of export controls and the intensifying competitive environment in the chip sector warrant careful attention.

In summary, the market is currently benefiting from a clearer trade outlook and validated growth in a key innovation sector. We advise clients to appreciate this positive momentum while maintaining a strategic awareness of the ongoing legal and geopolitical dynamics that continue to shape the investment landscape.
