The Multi-Trillion AI Tsunami Sweeping the Market

June 1, 2026 at 4:33 pm Leave a comment

Not only has Artificial Intelligence (AI) dominated headlines, but a multi-trillion-dollar investment tsunami is creating a rising tide that has lifted many AI-related stocks to market leadership. Since the seismic launch of OpenAI’s ChatGPT in November 2022, investors have rushed to participate in what may be one of the largest technology investment cycles in history.

At my firm, Sidoxia Capital Management, we have been positioned in the AI rush for several years—well before ChatGPT became a household name. Close followers of my work know I have been tracking the AI revolution for years (see my previous analysis on my Investing Caffeine blog.

Goldman Sachs recently published an in-depth report highlighting the various AI scenarios and assumptions underlying an estimated $4 trillion to $8 trillion spending boom on compute (AI chips), data center infrastructure, and power investments over the next five years. As shown in the chart below, Goldman’s baseline capital expenditures scenario models a staggering $7.6 trillion in spending from 2026 to 2031. While variables like the lifespan of NVIDIA GPUs can shift annual AI spending estimates by hundreds of billions of dollars, the numbers remain enormous under virtually any scenario.

Market Momentum: Another Record-Breaking Month

For the month, the major indexes once-again vaulted to new record highs, driven by the AI capital expenditure cycle and a record level of profits:

·      S&P 500: +5.2% (+10.7% year-to-date)

·      NASDAQ: +8.4% (+16.1% year-to-date)

·      Dow Jones Industrial Average: +2.8% (+6.2% year-to-date)

As I highlighted in last month’s post, it isn’t just speculative spending driving stock prices higher; it is an active AI productivity revolution that is causing corporate earnings to roar. This is especially true within the large-cap technology sector, which serves as the primary engine behind the S&P 500’s record-breaking performance.

It may seem counter-intuitive, but even as stock prices have reached record heights, valuations have actually become cheaper (sitting at a 20.9 forward P/E) compared to the peak price-to-earnings ratios seen in 2025. How is this possible? Quite simply, the denominator of the P/E ratio (earnings) has been growing at a faster clip than the numerator (stock prices), compressing the overall valuation multiple – see chart below.

The Quest for Efficiency

Ultimately, the objective of every publicly traded company is straightforward: increase profits and cash flow. For most businesses, labor remains the largest operating expense. One of the most effective ways to reduce labor costs and improve efficiency is through technology investment. The chart below highlights the growing role technology plays within the economy as companies increasingly invest in automation, software, cloud computing, and AI. These investments often improve productivity, expand margins, and enhance long-term profitability.

As this disruptive AI revolution permeates all sectors of the economy, we are witnessing the early stages of a productivity renaissance. Even as unemployment rates slowly creep higher (reaching 4.3% from a 2023 low of 3.4%), corporate profit growth is accelerating while nominal GDP continues to chug along at a steady rate (see chart below).

The Infrastructure Winners

Underlying this economic growth are the individual companies building the foundation of the AI boom. Just five months into the year, a select group of infrastructure and semiconductor hardware companies have posted astronomical returns in 2026*:

Underlying the growth in profits and the economy are the individual companies driving the AI infrastructure boom. Even though we are only five months through the year, here is a small list of companies benefiting from and contributing to the rocketing growth in 2026 (YTD % Gains)*:

·      Sandisk Corp. (SNDK) +604%

·      Micron Technology Inc. (MU) +240%

·      Dell Technologies Inc. (DELL) +234%

·      Intel Corp. (INTC) +211%

·      Western Digital Corp. (WDC) +208%

·      Sterling Infrastructure Inc. (STRL) +181%

·      Powell Industries Inc. (POWL) +168%

·      Comfort Systems USA Inc. (FIX) +96%

·      Vertiv Holdings Co. (VRT) +95%

*Sidoxia Capital Management and/or its clients hold positions in some of these companies (see Complete Strategy Performance and Disclosure at the bottom of this article or Click Here).

A major tailwind supporting these companies is the roughly $700 billion of capital expenditures expected in 2026 from hyperscale technology leaders such as Alphabet, Microsoft, Meta Platforms, and Amazon. These firms continue to aggressively invest in AI infrastructure to maintain competitive advantages and satisfy surging demand for AI-powered services – see AI Tech Spending article.

The Importance of Diversification (Even in a Hot Market)

At Sidoxia, our concentrated equity portfolios have significantly outperformed the S&P 500 index in 2026, as well as on a 1-year, 3-year, and 5-year basis. However, our winning exposure in AI infrastructure stocks has been partially offset by underperformance in the cryptocurrency, healthcare, and software/SaaS sectors. This includes drags from holdings like Exzeo Group, Inc. (XZO, -43% YTD), Salesforce Inc. (CRM, -28%), and Roper Technologies Inc. (ROP, -27%).

Ultimately, this underscores the necessity of a balanced portfolio: the positive contributions from our top-performing names heavily outweighed the negative drag from the laggards, allowing our concentrated strategy to come out ahead.

No Signs of Slowing, But Watch the Horizon

Euphoria surrounding the AI spending wave shows no signs of abating in the near term. The highly anticipated upcoming Initial Public Offerings (IPOs) from private giants like SpaceX (SPCX), Anthropic, and OpenAI will likely add fuel to investor excitement. This naturally begs the question: are we inflating another technology bubble?

Trees don’t grow to the sky forever, and the same fundamental law applies to investing—eventually, the parabolic gains will slow or reverse.

The AI tsunami is currently in full force, and while it has created massive wealth today, historical market cycles remind us that unmanaged momentum can eventually cause financial damage to unprepared investors. Right now, there is no shortage of demand for AI services and infrastructure, keeping the market tide exceptionally high. Sidoxia and its clients have benefited tremendously from this secular trend, but we remain highly vigilant and active in managing risk for when the tide inevitably turns.

Stay tuned, and ensure your portfolio is properly structured to navigate the waves ahead.
