A weekend meeting in November 2008 decided whether Citigroup could survive past Monday. After Lehman Brothers collapsed, global banks began to distrust each other's asset quality, and the short-term financing market nearly froze. Citi's stock price plummeted over 50% in a single week, depositors and counterparties started to withdraw, and Washington feared this globally operating bank would be the next giant to fall. The U.S. Treasury, Federal Reserve, and Federal Deposit Insurance Corporation ultimately intervened together: the Treasury injected another $20 billion, and the government provided loss protection for Citi's approximately $306 billion in loans, securities, and real estate-related assets on its books. Along with the previously received $25 billion, Citi cumulatively accepted $45 billion in TARP capital support. Eighteen years later, in Q2 2026, Citigroup achieved $24.8 billion in revenue and $5.8 billion in net profit, marking the highest quarterly revenue in a decade. More interestingly, this bank that survived thanks to government guarantees is now leveraging blockchain to offer 24-hour USD clearing, tokenized deposits, and digital private equity services. Citi's turnaround connects two waves of financial infrastructure transformation: the previous wave was the uncontrolled securitization, and this wave is traditional banks actively embracing on-chain settlement. The dream of a financial supermarket pushed Citi to become a global giant. In 1998, Citicorp merged with insurance group Travelers to form Citigroup. At that time, the U.S. financial industry was still governed by the Glass-Steagall Act

In the 1960s, flying from New York to Paris was still a grand occasion worth dressing up for. Travelers walked into the terminal wearing suits and dresses, with paper tickets tucked inside their passports. Flight attendants pushed silver carts through the cabin, serving meals on porcelain plates, while outside the window, the Atlantic Ocean was shortened by jet engines. The blue globe on the airplane's tail belonged to Pan American World Airways, commonly translated in Chinese as "Pan Am." In that era, Pan Am was almost the United States' business card to the world. It connected New York, London, Paris, Tokyo, Hong Kong, and South America, turning "global travel" from an adventurer's experience into a commodity affordable for the middle class. On December 4, 1991, this name that had flown for 64 years suddenly ceased operations. The world still needed air travel, and international routes even became busier. What disappeared was an industry giant that once defined global aviation standards but failed to adapt to changes in oil prices, policies, and capital rules. 1. It drew the first generation of globalization routes on the map Pan American Airways was founded in 1927, initially operating airmail and passenger services between Florida and Cuba in the United States. Founder Juan Trippe realized early on that an airline's core assets included not only airplanes but also air rights, airports, diplomatic relations, and infrastructure. At that time, many countries lacked mature airports, so Pan Am used "flying boats" capable of taking off and landing on water to establish long-distance routes between port cities. The company not only sold tickets but also participated in building meteorological, communication, maintenance, and navigation systems

In February 2026, Waymo completed a $16 billion financing round. Participants included Alphabet, Dragoneer, Sequoia Capital, Mubadala, and Temasek, among others. The presence of sovereign capital, tech giants, and venture capital on the shareholder list indicates that driverless taxis have moved from a technological experiment to a heavy-asset expansion phase. According to data disclosed by Waymo, the company completed 15 million rides in 2025; by early 2026, it had completed over 20 million rides cumulatively, with more than 400,000 orders per week, covering six major metropolitan areas in the United States. The next step is to establish operational infrastructure in more than twenty cities including Tokyo and London. Waymo financing and operational data⁠ Meanwhile, Chinese companies are also accelerating their overseas expansion. Baidu Apollo Go has launched fully driverless commercial operations in Dubai and is testing in markets such as London, Switzerland, and Hong Kong; Pony.ai has announced overseas plans and potential orders exceeding 4,000 vehicles, with plans to deploy over 2,000 vehicles in the European market through Uber. Baidu Q2 2026 performance⁠, Pony.ai overseas fleet plans⁠ Urban transportation is witnessing a new commodity: machine drivers that can be replicated, dispatched, and generate revenue calculated per kilometer. Twenty years of technology have finally met cities ready for expansion. The driverless driving boom can be traced back to the 2004 DARPA Challenge in the United States. At that time, no vehicle completed the desert course. A few years later, LiDAR, cameras, high-precision maps, and machine learning gradually matured, Go

On September 14, 2005, Delta Air Lines filed for bankruptcy protection in a New York court. At that time, this nearly 80-year-old airline was burdened with about $20.5 billion in debt and had accumulated nearly $10 billion in losses over the past four years. Rising oil prices, the expansion of low-cost airlines, pension burdens, and the post-9/11 travel slump all weighed heavily on its balance sheet. Even more perilous, the airline industry burns cash daily. Aircraft leases, employee salaries, airport fees, and maintenance expenses do not automatically disappear when passenger numbers decline. A company, even with valuable routes and fleets, can still crash on the runway if its cash flow cannot sustain until demand recovers. Twenty-one years later, Delta has become one of the most closely watched profitable companies in the U.S. airline industry. In the second quarter of 2026, the company’s revenue reached $19.8 billion, with adjusted operating income of $1.6 billion; Berkshire Hathaway, led by Warren Buffett, also purchased about $2.65 billion worth of Delta shares in the first quarter of 2026. This turnaround spans bankruptcy, financial crises, global mergers and acquisitions, pandemic flight suspensions, and energy shocks, and it has redefined how airlines make money. After 9/11, the old airline model lost its support. In the latter half of the 20th century, major U.S. airlines established a typical hub model. They operated complex domestic and international routes, employed large numbers of long-term staff, bore pension and healthcare benefits, and relied on business travelers to pay high ticket prices. As long as the economy grew and corporate travel was strong, this system could

Small Modular Nuclear Power: AI Competing for Electricity, Nuclear Power Begins Factory Production In August 2026, TerraPower, founded by Bill Gates, signed a cooperation agreement with South Korea's SK Innovation to jointly participate in small modular reactor projects in the United States and overseas. South Korean companies aim to provide key equipment, engineering construction, and operational capabilities, transferring supply chain experience accumulated from shipbuilding, refining, and large machinery industries into the new generation nuclear power sector. A few months ago, the U.S. Department of Energy selected eight companies to provide over $94 million in funding to help address licensing, supply chain, and site preparation issues for small modular reactors. Another federal fund of up to $800 million was allocated to TVA and Holtec to advance the first projects in Tennessee and Michigan. The U.S. Department of Energy announced the TVA and Holtec projects in May 2026. The revival of nuclear power has been advocated for many years. The force bringing it back into capital focus now comes from a very modern scenario: AI data centers are lining up to compete for electricity. Why AI is putting nuclear power back on the table Over the past decade, the global power system has mainly expanded around wind, solar, and natural gas. Renewable energy costs have rapidly declined, and construction cycles are shorter than nuclear power, but data centers require continuous year-round operation. Model training cannot be paused midway due to cloudy days, no wind, or grid congestion, so companies need stable, low-carbon power sources. Traditional large nuclear power plants can provide stable baseload power, but the problem lies in the engineering scale. Each power plant is too large to...

Around the year 2000 in the United States, spending weekends browsing bookstores was a very formal leisure activity. People would walk into the warmly lit Borders inside the mall, first flipping through a few novels in the new books section, then going to the music section to listen to CDs. The bookstore smelled of coffee, had wooden bookshelves, and sofas where you could sit for hours. Students came here to find research materials, parents brought their children to book clubs, and people just off work would casually buy a magazine. At that time, large chain bookstores seemed to have everything the internet couldn't replicate: space, atmosphere, inventory, professional staff, and the serendipitous feeling of encountering books. Ten years later, the same bookshelves were labeled with clearance discounts, the coffee machines were removed, and even the tables and chairs became items for sale. Readers did not disappear, and the global book market did not stop operating. What disappeared was the era when consumers had to drive to large bookstores to find a book. 1. It turned bookstores into cultural department stores Borders was founded in 1971 in Ann Arbor, Michigan, by brothers Tom and Louis Borders. They were early adopters of computer systems to track inventory and regional sales data. While many independent bookstores still relied on the owner's experience to stock books, Borders was already able to analyze reading preferences in different cities and then decide which books each store should carry. In the 1990s, suburbanization in the U.S., shopping malls, and large retail businesses expanded simultaneously. Malls needed anchor stores that could attract customers long-term, and consumers were accustomed to completing shopping, dining, and entertainment in one trip by car. Borders seized this cycle. It expanded the traditional bookstore

1973, Memphis Airport, USA. Fourteen purple and white small cargo planes were parked beside the runway, with 389 employees waiting for packages to be delivered to the sorting center. FedEx received only 186 shipments on its first night but had to fly to 25 U.S. cities. This system was expensive from day one: planes, fuel, pilots, airports, trucks, and sorting centers all had to be prepared in advance, but revenue would only appear after customers developed the habit of "overnight delivery." A few months later, the first oil crisis broke out, causing aviation fuel costs to soar. FedEx continued to lose money, financing was nearly cut off, and founder Fred Smith was even unable to pay the next week's fuel bill. Today's FedEx connects more than 220 countries and regions. In fiscal year 2026, revenue reached $94.7 billion, and the value of goods handled annually impacts global manufacturing, consumption, e-commerce, and supply chains. However, when this logistics empire was just starting, there was only $5,000 left in the account. A logistics concept that received low marks from a professor In 1965, Fred Smith was still a Yale University student. In his thesis, he proposed a new transportation model: consolidating goods from different cities to a central hub, sorting them overnight, and then flying them to their destinations. This "hub-and-spoke network" is very similar to a bank clearing center. Planes do not need to fly directly from every city to all destinations; they only need to fly to Memphis uniformly and then redistribute from Memphis. The more cities, the greater the network value, and the marginal efficiency of adding new routes also increases. At that time, U.S. freight mainly relied on passenger plane belly
