SpaceX 潜在的巨大首次公开募股（目标估值：1.78 兆美元）和其他市场动态引发了人们对我们是否正在进入一个由人工智慧、能源、国防和制造业升级所驱动的全球新投资超级周期的思考。全球在 2025 年于人工智慧、清洁能源和国防领域的支出已达 6.9 兆美元，预计到今年年底将达到 10 兆美元，并在 2030 年达到 16 兆美元。这些领域相互强化；人工智慧的扩张需要巨大的能源规模，这与中国的清洁能源转型相契合，而地缘政治的转变则要求增加国防开支。

此外，供应链的脆弱性促使了大量的国内制造业再投资。在美国，有 25% 的进口制造商品存在关键的供应脆弱性。要在美国国内完全生产这些高度暴露于贸易风险的商品，将需要 2 兆美元来升级工厂、设施和基础设施，其中约有一半（1 兆美元）的资金可能会流入美国制造业。金融能力依然庞大：美国金融资产价值达到创纪录的国内生产总值（GDP）的 6.5 倍，截至 2025 年 12 月，美大家庭持有 68 兆美元的股票（占家庭财富创纪录的 37%），另有 8 兆美元存放于货币市场基金。

然而，资源竞争导致了短期限制，例如数据中心与住房建设争夺土地，以及「晶片通膨」提高了消费性电子产品的价格。尽管这些动态使利率在更长的时间内保持在较高水平并引发市场波动，但这些领域的全球增长可能会防止经济衰退。正如投资人 Jay Pelosky 所指出的，一个由自我生产、自我消费和自我融资的区域所组成的「三极世界」可能会出现，这预示著资本市场一体化可能迎来一个黄金时代。

SpaceX's potentially massive IPO (target valuation: $1.78tn) and other market dynamics raise questions about whether we are entering a new global investment super-cycle driven by AI, energy, defence, and manufacturing upgrades. Globally, $6.9tn has been spent on AI, clean energy, and defence in 2025, with projections estimating these outlays will reach $10tn by the end of this year and $16tn by 2030. These sectors are mutually reinforcing; AI's expansion requires massive energy scaling, which aligns with China's clean-energy transition, and geopolitical shifts demand increased defence expenditures.

Furthermore, supply chain vulnerabilities prompt significant domestic manufacturing reinvestment. In the US, 25% of manufactured goods imports have critical supply vulnerabilities. Fully producing these trade-exposed goods domestically would require $2tn in upgrades for factories and infrastructure, with around half ($1tn) likely to flow into US manufacturing. Financial capacity is substantial: US financial assets stand at a record 6.5x of GDP, with households holding $68tn in equities (37% of household wealth) by December 2025, alongside $8tn in money market funds.

However, resource competition causes short-term constraints, such as data centres competing with housing and "chipflation" raising consumer electronics prices. While these dynamics keep interest rates higher for longer and cause market volatility, the global growth in these sectors might prevent a recession. Ultimately, as investor Jay Pelosky notes, a "tripolar world" of self-producing, self-consuming, and self-financing regions could emerge, signaling a potential golden era of integrated capital markets.
