U.S. AI vs China AI – the difference

China and U.S. AI

China’s AI industry has indeed cultivated a reputation for ‘doing more with less’, while the U.S. has poured vast sums into AI development, raising concerns about overinvestment and inflated valuations.

The contrast lies not only in the scale of funding but also in the efficiency and strategic focus of each country’s approach.

The U.S. Approach: Scale and Spending

The United States remains the global leader in AI infrastructure, driven by massive private investment and access to advanced computing resources.

Venture capital deals in U.S. AI and robotics startups have more than quadrupled since 2023, surpassing $160 billion in 2025.

This surge has produced headline-grabbing valuations, such as humanoid robotics firms raising billions in single rounds. Yet analysts warn of bubble risks, with valuations often detached from sustainable revenue models.

The U.S. strategy prioritises scale: building the largest models, securing the most powerful GPUs, and attracting top-tier talent.

This has led to breakthroughs in generative AI and large language models, but at extraordinary cost.

Estimates suggest that OpenAI alone has spent over $100 billion on development. Critics argue this reflects a ‘more is better’ philosophy, where innovation is equated with sheer financial muscle.

China’s Approach: Efficiency and Restraint

China, by contrast, has invested heavily but with a different emphasis. In 2025, Chinese AI investment is reportedly projected at $98 billion, far below U.S. levels.

Yet Chinese firms have achieved notable progress by focusing on cost-efficient innovation. For example, AI2 Robotics developed a model requiring less than 10% of the parameters used by Alphabet’s RT-2, demonstrating a commitment to leaner, more resource-conscious design.

Foreign investors are increasingly drawn to China’s cheaper valuations, which are roughly one-quarter of U.S. equivalents.

This efficiency stems from lower research costs, government-led initiatives, and a culture of frugality shaped by regulatory pressures and limited access to advanced hardware.

Rather than chasing scale, Chinese firms often prioritise practical applications and affordability, enabling broader adoption across industries.

Doing More with Less?

The evidence suggests that China has achieved competitive outcomes with far fewer resources, while the U.S. has arguably overpaid in pursuit of dominance.

However, the U.S. still leads in infrastructure, talent, and global influence. China’s strength lies in its ability to innovate under constraints, turning scarcity into efficiency.

Ultimately, the question is not whether one side has ‘overinvested’ or ‘underinvested’, but whether their strategies align with long-term sustainability.

The U.S. risks a bubble fuelled by excess capital, while China’s leaner approach may prove more resilient. In this sense, China is indeed ‘doing more with less’—but whether that will be enough to surpass U.S. dominance remains uncertain.

Bubble vulnerability

The sheer scale of U.S. AI investment has left the industry vulnerable to bubble shock, as valuations and spending appear increasingly detached from sustainable returns.

Analysts warn that the U.S. equity market is showing signs of an AI-driven bubble, with trillions poured into data centres, chips, and generative models at unprecedented speed.

While this has fuelled rapid innovation, it has also created irrational exuberance reminiscent of the dot-com era, where hype outpaces monetisation.

If growth expectations falter or capital tightens, the U.S. could face sharp corrections across tech stocks, credit markets, and employment, exposing the fragility of an industry built on extraordinary but potentially unsustainable levels of investment.

Amazon goes nuclear, to invest more than $500 million to develop small modular reactors (SMR)

AWS nuclear power

Amazon Web Services (AWS) has announced the signing of an agreement with Dominion Energy, the utility company of Virginia U.S., to explore the development of a small modular nuclear reactor near Dominion’s existing North Anna nuclear power station.

As Amazon’s cloud computing subsidiary, AWS has an ever-growing demand for clean energy, particularly as it expands into generative AI. This agreement aligns with Amazon’s journey towards net-zero carbon emissions.

Amazon joins other major tech companies like Google and Microsoft in turning to nuclear power to meet the increasing energy needs of data centres.

Energy hungry data centre power solution

AI data centre

The use of nuclear reactors for data centres is a controversial and complex topic that has both advantages and disadvantages

Nuclear reactors can provide a reliable, stable, and carbon-free source of electricity for power-hungry data centres, which are essential for the operation of various applications, such as artificial intelligence (AI).

Grid overload

Nuclear reactors can also reduce the dependence on the existing grid, which may be vulnerable to blackouts, fluctuations, or cyberattacks. On the other hand, nuclear reactors require a high initial investment, as well as strict safety and regulatory standards. Nuclear reactors also pose potential risks of radiation, waste disposal, and proliferation. Moreover, nuclear reactors may not be suitable for all locations, as they may face public opposition, environmental concerns, or geopolitical issues.

Small Modular Reactor (SMR)

One of the possible solutions to these challenges is to use small modular reactors (SMRs), which are advanced reactors with about a third of the power generation of a traditional, large nuclear plant. SMRs are designed to be more flexible, scalable, and cost-effective than conventional reactors, as they can be built off-site and transported to the desired location. SMRs can also be integrated with renewable energy sources, such as solar or wind, to create a hybrid system that can balance the power demand and supply.

However, the technology of SMRs is still in its early stages of development and deployment, and there are currently no data centres in the world that use built-in nuclear reactors. Therefore, it remains to be seen whether nuclear reactors will become a common or viable option for future data centres. The decision to use nuclear reactors for data centres should be based on a careful evaluation of the benefits and risks, as well as the alternatives and trade-offs, of each specific case.

It has been calculated that a ‘norma’ data centre (whatever that is), needs 32 megawatts of power flowing into the building. For an AI data centre, it’s closer to 80 megawatts.

AI systems are using all this extra electricity simply because they are doing so much more processing than standard computing. They are chewing through far more data.

As AI continues to develop, so too will the power requirement needed to run these monsters.
