The Great AI Decoupling Begins
Capital is cold. It does not care about manifestos or the utopian dreams of Silicon Valley. On October 29, 2025, Nvidia reached $5.03 trillion in market value, a number larger than the GDP of almost every nation on Earth. But beneath this towering valuation, the narrative of inevitable AI superintelligence is beginning to crack. The momentum that carried the S&P 500 to record highs earlier this year is meeting a brutal reality: the models are stalling.
Diminishing Returns in the House of Altman
The August release of GPT-5 was supposed to be the ‘Oppenheimer moment’ for artificial general intelligence (AGI). Instead, it was a quiet thud. Users found a system that, while faster and more agentic, still struggled with the same logical hallucinations that plagued its predecessors. According to internal benchmarks leaked following the botched rollout of GPT-5, the leap in reasoning capabilities was less than 3 percent over GPT-4o. The scaling laws, once thought to be the infinite ladder to godhood, are hitting a wall of data exhaustion and energy constraints.
| Benchmark | GPT-4 (March 2023) | GPT-5 (August 2025) | Improvement Delta |
|---|---|---|---|
| MMLU (General Knowledge) | 86.4% | 88.9% | +2.5% |
| HumanEval (Coding) | 67.0% | 71.2% | +4.2% |
| GSM8K (Math Reasoning) | 92.0% | 93.5% | +1.5% |
The Circular Finance Trap
Follow the money to find the risk. Investigative analysis into the third-quarter filings reveals a troubling pattern of circular financing. In September 2025, Nvidia funneled an estimated $100 billion into OpenAI. Much of that capital is immediately earmarked to purchase Nvidia’s own Blackwell-2 chips. This creates a closed-loop revenue cycle that inflates valuations without proving real-world enterprise utility. If OpenAI cannot turn GPT-5 into a profitable agentic workforce, the $1.4 trillion Stargate infrastructure plan becomes the world’s most expensive collection of silicon paperweights.
A Hawkish Pivot Rattles the Bulls
The macro environment is no longer providing a safety net. As of yesterday, November 13, 2025, the market’s optimism for a holiday interest rate cut has evaporated. Traders had priced in a 95 percent chance of a Federal Reserve easing in December. That number has plummeted to 53 percent following persistent inflation data and hawkish signals from Jerome Powell. The cost of borrowing to fund massive data centers is rising just as the revenue growth from those centers begins to plateau. On the news, the Nasdaq Composite dropped nearly 2 percent, led by a sharp sell-off in the ‘Magnificent Seven.’

The Technical Impasse of System 2 Thinking
The core of the skepticism lies in the failure of ‘Reasoning Models’ to achieve true autonomy. Modern AI relies on a ‘Chain of Thought’ mechanism that simulates reasoning by predicting the next logical step in a sequence. However, as Stanford researchers noted last month, these systems lack a world model. They are stochastic calculators, not conscious problem solvers. When faced with the ‘Novelty Test’ (problems that do not exist in the training data), GPT-5’s performance drops by 40 percent. This technical ceiling suggests that superintelligence is not a matter of adding more GPUs, but of a fundamental architectural breakthrough that has not yet occurred.
Venture Capital and the Exit Mirage
The private markets are sensing the frost. Venture funding for AI startups, which represented 58 percent of all VC activity earlier this year, has begun to rotate toward ‘Agentic Efficiency’ rather than ‘Foundation Models.’ The era of the $10 billion pre-revenue seed round is over. Investors are demanding to see the ‘Return on Compute’ (ROC). With OpenAI projecting annual losses to triple to $14 billion by 2026, the pressure to deliver a ‘God-in-a-box’ has never been higher, or more desperate.
The next critical data point for every investor arrives on November 19, 2025. Nvidia will report its Q3 earnings, and the market will be looking past the revenue beat to the shipment guidance for the Blackwell-2 architecture. If the hyperscalers like Microsoft and Meta signal a slowdown in chip orders, the $5 trillion market cap will be the first domino in a massive deleveraging event.
