American Bubble and European Delay

Will the artificial intelligence bubble burst? The question mark adds to the dilemmas that the crisis in the world order is fuelling with debt, rearmament, protectionism, wars, and illusory peace agreements. After many years in which stock markets have weathered persistent headwinds, becoming the emblem of capital’s resilience to its own crises, the accumulated risks are coming to the surface. High technology, the newest sector of listed companies, has become a magnet for investment, producing in just a few years giants with unprecedented market values.

The Magnificent Seven in the sector (Alphabet, Meta, Microsoft, Amazon, Apple, Nvidia, Tesla) have a combined market capitalisation of around $22 trillion, about 35% of the total of the 500 largest US corporations. The artificial intelligence (AI) champion Nvidia alone has a market capitalisation of $5 trillion. In November, when third-quarter corporate financial statements were presented, uncertainties about capital expenditure, profitability, debt, chip obsolescence times, and the energy costs of these technologies caused significant shocks in the sector’s share prices. This bubble, like all those that preceded it, will see alternating euphoria and panic. Once again, we will witness the power and drama of capital.

Two bubbles

According to the Financial Times, since OpenAI launched ChatGPT in November 2022, AI-related companies have increased their stock market value by 165%, compared to an overall increase of 70% in the S&P 500 index. A comparison with the dot-com bubble shows that, in the last three years of the bubble, from December 1996 to March 2000 when it burst, the S&P 500 general index grew by 110%, while the NASDAQ index of technology stocks tripled its capitalisation in the last 18 months of the bubble [William Quinn and John D. Turner, Boom and Bust, Cambridge University Press, 2020]. The cyclically adjusted price-to-earnings ratio of the S&P 500 index, dear to scholars of stock market ups and downs, reached 45 in the last phase of the dot-com bubble (i.e., the average company on the Wall Street stock exchange was valued at 45 years of its earnings). Today it stands at 38.

The diversity of the geopolitical context, technological content, and economic power does not allow for easy comparisons between the two bubbles, but today’s bubble appears to be in a more lukewarm phase than the dot-com bubble. However, it should be noted that markets are not compartmentalised. In a recent study, the Federal Reserve drew attention to the financial indebtedness of hedge funds, which has reached a record level of $6.2 trillion, up more than 25% from a year ago. At the same time, large banks have lent $1.7 trillion to non-bank financial businesses. Some of this flood of money will inevitably end up in the AI bubble. However, there are other sectors and activities that demand real or fictitious capital, not least States that need to finance their debts and the arms industry.

A sign of vulnerability to external collisions came in January, when Chinese start-up DeepSeek launched its own AI model at a much lower cost than that of OpenAI and Nvidia’s processors. The latter, in a single day of panic, lost $590 billion in market capitalisation. But that did not stop investment flows to the magnificent seven giants. Morgan Stanley estimates that between 2025 and 2028, big businesses will spend around $3 trillion on building AI data centres.

So far, the AI groups’ investments have been largely self-financed by the growth of their share capital and cash flows. In the four-year period indicated above, more than half of the expenditure will come from external financing, $1.15 trillion from private credit and $350 billion from bond issues and securitisation. The Wall Street Journal describes a circular financing model among these groups, illustrated as follows: Oracle buys Nvidia chips, Nvidia commits $100 billion to OpenAI, OpenAI has long-term purchase commitments from Oracle for $300 billion. These circuits are reminiscent of the suspect relationships with which banks, non-bank financial groups, and special-purpose vehicles created an artificial market to fix the prices of toxic securitised products during the 2005-2007 real estate bubble.

Banks, builders, data centres, and turbines

Large spending and debt plans disrupted the market in November, but — writes the WSJany concerns on Wall Street about a possible investment bubble have largely been trumped by the fear of being left behind. Virtually every Wall Street player is angling to get a piece of the action, from banks such as JPMorgan Chase and Morgan Stanley to traditional asset managers such as BlackRock. The Wall Street Journal rediscovers a side of stock market psychology: the desire to squeeze every last drop out of the bull market. In 2007, the then-CEO of Citigroup Chuck Prince theorised: As long as the music is playing, you’ve got to get up and dance.

Less well-known but cash-rich companies are entering the fray, fund managers such as Blue Owl have amassed trillions of dollars of investing firepower and have been hunting for big deals where they can put that money to work. Blue Owl is building eight data centre buildings in Abilene, on the border of West Texas, the epicentre of oil fracking, which will consume 1.2 GW of energy, enough to power about one million homes. Oracle will lease the centres for fifteen years. The construction of these infrastructures and the energy plants that will power them are the main facts supporting the thesis that what is underway is an industrial bubble, and not just a speculative one.

The enthusiasm that inflates the bubble shines through in announcements and forecasts. Morgan Stanley signed $75 billion worth of deals in one week to finance data centres. Google, Amazon, Meta, and Microsoft have spent $350 billion on data centres this year and plan to spend another $400 billion in 2026. The Financial Times has put the surge in gas turbine production under the microscope. In connection with AI, gas turbines in the US have been revitalised after a period of stagnation during the boom in renewable energy. According to consulting firm Dora Partners, the sector received 1,025 orders in 2025, including 183 for large turbines, an increase of 50% compared to the average over the last five years. The Department of Energy predicts that data centres will consume 6.7-12% of US electricity by 2028, compared to 4.4% in 2023.

This phenomenon is not unique to the United States: the IEA predicts that global electricity consumption by data centres will double by 2030, reaching 945 TWh, more than Japan’s current energy consumption. The three big groups in the turbine sector in the US (America’s GE Vernova, Japan’s MHI-Mitsubishi, and Germany’s Siemens Energy), which were in a severe demand crisis a few years ago, are now in a supply crisis, with orders for the next three years. According to the London newspaper, this bottleneck in the supply of American and Japanese turbines is worrying emerging Asian countries, which are facing growing demand for electricity. This could also be an opportunity for China to exploit.

US-EU technology gap

The battle for artificial intelligence has an uncertain timeline; it is conceivable that it will have applications in every field of human creative and destructive activity, but essentially it is a battle for productivity and a battle for capital. The US capital market is once again demonstrating its power. Nevertheless, the fact that, after the first black day in November, one of the most active technology companies called for government intervention is indicative of how tough the battle is.

OpenAI’s chief financial officer, Sarah Friar, called for the government to play a role, complementing an ecosystem of banks [and] private equity, as a backstop, a guarantee that allows the financing to happen. The White House’s artificial intelligence czar, David Sacks, immediately ruled out bailouts for AI companies: The US has at least five major frontier model companies developing cutting-edge AI models. If one fails, others will take its place. This cynicism is part of the strength of American capitalism, but it has never prevented the government from intervening.

In his report on competitiveness, Mario Draghi denounced the innovation gap between the European Union and its competitors, the US and China above all. Europe did not capitalise on the first digital revolution driven by the internet and is now also lagging behind in revolutionary digital technologies. About 70% of basic artificial intelligence models have been developed in the US, and just three US 'hyperscalers' account for over 65% of the global and European cloud market. [...] Quantum computing is set to be the next big innovation, but five of the world’s top ten technology companies in terms of quantum investment are based in the US and four in China (none in the EU).

For now, Europe will be watching the battle for AI only from afar.

Reckless Bets on Migrants in California

Internationalism No. 78-79, August-September 2025 Page 11 From the series Chronicles of the new American nationalism The tariffs imposed by President Donald Trump on allies, partners and opponents of the United States have opened a phase of negotiations with the affected countries and caused reactions from some key States. The legal opposition from almost all areas of the US poses a test: whether States, courts, and Congress can influence trade policy and constrain the expansion of executive powers. Amid conflicting rulings, the tariffs have been reinstated – an outcome that, The New York Times remarks, has “left Washington, Wall Street, and much of the world trying to discern the future of US trade policy”. California’s dispute with the federal government has expanded to immigration policy and the domestic use of military force. The political, economic, and power struggle...

Electoral Upheaval and Turmoil Inside Labour

Unlike presidential systems such as the American one, "the British system elevates members of the cabinet to the highest echelons of their party". The prime minister's authority "rests primarily on the maintenance of party discipline" because "the dissent of an influential clique, or the machinations of a single magnetic personality, can limit the premier's ability to pursue desired political objectives". "In extraordinary circumstances", warns Kissinger, ...

Multiple Games in the Third Gulf War

Internationalism No. 88, June 2026 Page 6 The conflict in the Gulf has entered its third month, marked by a precarious truce that reflects a strategic stalemate, with Tehran’s “selective blockade” of Hormuz and the US Navy’s “counter-blockade” of Iranian ports. According to the Pakistani daily Dawn , bilateral negotiations — mediated by Islamabad with the explicit support of Riyadh and the “discreet and indirect” backing of Beijing — appear to centre on the price of reopening the energy artery. For Washington, writes the Saudi newspaper Asharq al-Awsat , the negotiations should yield some kind of “tangible result” on the nuclear issue, allowing both sides to “claim victory”, given that the priority is resuming commercial traffic. To this end, granting Tehran the opportunity to collect some form of revenue has not been ruled out. Iranian “pragmatic” factions are raising the idea of maritime tr...

An Italianised Europe

Internationalism No. 88 - June 2026 Page 2 In almost four years in government, Italy’s renewed stability has been a key asset for Giorgia Meloni, also encouraging the European adaptation of the italian-style immigrants . However, the backlash from the referendum defeat, a real own goal, has opened a glaring rift that runs through both the end of the current legislature and the prospects for the next. There is debate over the political exhaustion of her government, forced to navigate the narrow path of budgetary statistics and under the threat of what the Financial Times has termed a “coming energy crisis” triggered by the blockade of the strait of Hormuz. At the referendum polls, the left-wing broad coalition “discovered” that it could compete with the centre-right, but no poll shows any substantial changes in the balance of power. The scenario of a “deadlock”, or a narrow majority for one...

Opportunities for the Euro and Yuan

Internationalism No. 77, July 2025 Page 13 Estimates by international institutions for April to June confirm the slowdown in global output and trade. The World Bank forecasts a decline in GDP growth from 2.8% in 2024, to 2.3% in 2025, and a sharp fall in trade from 3.4% to 1.8%. The main cause of the new slowdown is the tariff war declared by Donald Trump, who has so far imposed a universal minimum tariff of 10%. The uncertainty arising from his peculiar art of the deal , consisting of lunges, postponements, relaunches, U-turns, and pauses, makes the policy of the world's leading power unpredictable. It is also paying the highest price, with US growth halving, from 2.8% to 1.4%. The Eurozone has been floating at a rate of less than 1% since 2023 and, according to the World Bank, will remain below this level in 2025 and 2026, while the OECD and the ECB predict a return to 1% in 2025.

Beijing, Ambivalent About the G2, Opts for Temporary Stability

Internationalism No. 88, June 2026 Pages 4 and 5 Kolkata's The Telegraph announces "a rupture with the principle of post-War pacifism: that Japan and Germany had adhered to for decades". The West Bengal-based newspaper was founded in 1982 by Aveek Sarkar, a former protégé of Harold Evans at The Sunday Times in London. The editorial highlights certain aspects worth noting. First and foremost, there is a psychological dimension to the crises in the world order . The ideologies of the post-war order, imposed on the defeated bourgeoisies of Germany and Japan for decades, have permeated the whole of society to the point of becoming second nature that shape the German and Japanese ruling classes themselves. But today, a re-evaluation of these ideologies is in turn being imposed by an uneven development that, over the long term, has been economic, political, and military. This is a Z...

The Four Petrochemical Giants

Internationalism No. 86, April 2026 Page 15 From the series Major industrial groups in China When the People's Republic of China was founded in 1949, oil extraction in the country was practically non-existent, and the country was completely dependent on imports. The exploration and development of domestic oil resources required a major effort. As Jin Zhang reports in his book Catch-up and Competitiveness in China [Routledge, 2004]: The required massive human resources were supplied by the People's Liberation Army (PLA). In 1952, Mao Zedong ordered the reorganisation of the 57 th Division of the 19 th Army of the PLA into the 1 st Division of Oil . The effort led to the discovery of several oil fields, the most significant of which was in Daqing, Heilongjiang Province, in northeastern China, in 1959. It became operational the following year, reaching a ...
