## Introduction: The “Boring” Company That Just Passed the S&P’s Toughest Test

This week, the S&P 500 Index Committee made a decision that will reshape the benchmark for millions of American 401(k) accounts. On Thursday, S&P Dow Jones Indices announced that **Marvell Technology (MRVL)** would be added to the S&P 500 effective prior to the open of trading on Monday, June 22, 2026 .

The announcement came amid one of the most volatile weeks in recent memory for the semiconductor sector. The Nasdaq had just suffered its worst drubbing since the Iran war began. Broadcom had lost a quarter of its value in two days. Yet, in the midst of the carnage, Marvell was quietly earning a promotion to the most exclusive club in American finance.

Why does this matter? Because **passive investing** has taken over Wall Street. Approximately $7.5 trillion in assets are tied to the S&P 500 . When a stock joins the index, the managers of index funds—the Vanguards, the BlackRocks, the State Streets of the world—are forced to buy it, regardless of valuation, regardless of sentiment. It is the closest thing to a guaranteed bid in the stock market.

But unlike the speculative darlings of the AI boom, Marvell’s path to the S&P 500 was paved with something far more boring—and far more sustainable: **profitability**.

To join the S&P 500, a company must meet three strict requirements. It must have been publicly traded for at least 12 months. At least 10% of its shares must be available to the public (the “float”). And critically, it must report positive earnings under Generally Accepted Accounting Principles (GAAP) in its most recent quarter and cumulatively over the previous four quarters .

SpaceX, which is set to go public next week in the largest IPO in history, is not eligible because it has never reported a full year of GAAP profit . OpenAI and Anthropic are not eligible. But Marvell? Marvell passed the test .

The company’s data center revenue surged 46% last year, with its custom AI processor business doubling . Total revenue hit $8.2 billion in fiscal 2026, a 42% increase . The growth is accelerating. And the S&P committee took notice.

In this deep-dive, we will break down the profitability numbers that got Marvell into the index, explain the “passive buying tsunami” that follows an S&P 500 addition, and analyze whether the stock is a buy at current levels after a 16% pullback.

> **The Bottom Line Up Front:** Marvell is not the flashiest AI stock. It does not make the headline-grabbing GPUs that power ChatGPT. But it makes the **networking chips, optical interconnects, and custom ASICs** that hold the AI data centers together. Its business is steady, profitable, and deeply embedded in the infrastructure of the AI revolution. The S&P 500 nod is a recognition that the “picks and shovels” era of AI has arrived—and it is here to stay.

## Part 1: The S&P 500’s “No Hype” Rule

Before we get into Marvell’s specific numbers, it is worth understanding why this addition is so significant.

### The 4-Quarter Profitability Wall

The S&P 500 is not a “biggest companies” list. It is a curated index with entry tests . The committee—a small, anonymous group of executives at S&P Dow Jones Indices—has the power to bend the rules, but historically, they have refused to waive the fundamental requirement of **GAAP profitability**.

For a company to be considered, it must report positive earnings in the most recent quarter and cumulative positive earnings over the four prior quarters.

This is the wall that SpaceX, OpenAI, and Anthropic cannot climb. Despite their massive valuations, none of them have reported a full year of GAAP profit. Until they do, the S&P 500’s door remains closed .

### The Float Requirement

The second hurdle is the **public float** requirement. At least 10% of a company’s shares must be available to public investors . SpaceX’s IPO filing suggests its float will be only 3-4% . This not only keeps it out of the index but also caps the amount of passive demand it could generate even if it were included.

### The “New Class” of AI Stocks

Marvell’s addition represents a shift in the AI investment landscape. The first wave of the AI boom was about the **enablers**—Nvidia, Broadcom, TSMC. The second wave is about the **infrastructure**. Marvell sits squarely in that second wave.

Needham analyst recently reiterated a Buy rating on Marvell with a $150 price target, citing the company’s ability to secure a third North American hyperscaler customer for its custom silicon . This is not a company riding a single product wave. It is a diversified semiconductor supplier with multiple growth drivers.

| S&P 500 Requirement | Marvell Status | SpaceX Status |

| :--- | :--- | :--- |

| **12 months public trading** | Met (traded for decades) | Not yet (IPOs June 12) |

| **4 consecutive quarters GAAP profit** | Met (profitable) | Not met ($4.9B loss in 2025) |

| **10% public float** | Met | Estimated 3-4% |

## Part 2: The Profitability Story – How Marvell Passed the Test

Now, let us look at the numbers that got Marvell over the line.

### The $8.2 Billion Year

Marvell’s fiscal 2026 results (the fiscal year ending January 31, 2026) were a testament to the AI boom’s impact on the networking and custom silicon segments.

| Metric | Fiscal 2026 | Fiscal 2025 | Change |

| :--- | :--- | :--- | :--- |

| **Total Revenue** | $8.2 billion | $5.8 billion | **+42%** |

| **Data Center Revenue** | $6.0+ billion | $4.1 billion | **+46%** |

| **Custom Processor Revenue** | Doubled | Baseline | **+100%** |

| **Non-GAAP EPS** | $2.84 | $1.57 | **+81%** |

*Source: *

The data center business is the engine. It now represents roughly 75% of total revenue, up from about 70% a year ago. This concentration is a risk—if AI data center spending slows, Marvell will feel the pain. But for now, the growth is accelerating, not decelerating.

### The $2.5 Billion AI Forecast

In its “Accelerated Infrastructure for the AI Era” investor event, Marvell laid out ambitious targets:

- **AI revenue expected to exceed $2.5 billion in fiscal 2026**, compared to over $1.5 billion in fiscal 2025 and over $550 million in fiscal 2024 .

- That represents **66% year-over-year growth** in AI revenue.

The company also announced it has secured a **third North American hyperscaler customer** for its custom silicon—and this new customer is expected to generate more revenue than the first two combined .

**The TAM Opportunity:** Marvell updated its Data Center Total Addressable Market (TAM) forecast to exceed **$75 billion in 2028**, with the company’s goal to secure 20% share of this TAM long-term . That implies a long-term data center revenue opportunity of $15 billion—nearly double its current total company revenue.

### The Q1 2026 Beat

The most recent quarter (Q1 of calendar 2026, which ended in April) continued the momentum:

| Metric | Q1 2026 Actual | Analyst Estimates | Result |

| :--- | :--- | :--- | :--- |

| **Revenue** | $2.42 billion | $2.41 billion | **Beat** |

| **Adjusted EPS** | $0.80 | $0.79 | **Beat** |

| **Q2 Revenue Guidance** | $2.7 billion (midpoint) | $2.62 billion | **Beat** |

| **Q2 EPS Guidance** | $0.93 (midpoint) | $0.90 | **Beat** |

*Sources: *

CEO Matthew Murphy highlighted that “robust demand is reflected in our guidance for the second quarter,” emphasizing the company’s ability to scale supply and execution in response to accelerating customer requirements for AI infrastructure .

The company expects a **40% spike in data center revenue in fiscal 2027**, while overall revenue is anticipated to grow by 34% to $11 billion .

**The Human Touch:** For the engineer at Marvell, the S&P 500 inclusion is a validation of years of work. The company was not a household name during the 2010s. It was a solid, profitable chipmaker, but it was not flashy. The AI boom changed that. The custom chips that Marvell designs for Amazon, Microsoft, and now a third hyperscaler are the hidden engines of the AI revolution. They do not make headlines. They make revenue.

## Part 3: The Passive Tsunami – What Happens on June 22

Now, let us talk about the money. When a stock joins the S&P 500, passive funds are forced to buy it.

### The $7.5 Trillion Wall

According to Bloomberg Intelligence, about **$7.5 trillion in passive funds** track the S&P 500, with another **$3.4 trillion in active assets** benchmarked against it .

When the index adds a stock, every one of those funds must buy shares to maintain their tracking. This is not a “maybe.” It is a mathematical certainty.

### The Weighting Math

Marvell’s weight in the S&P 500 will be determined by its **float-adjusted market capitalization**. The company’s market cap is approximately $240 billion . Its float is nearly the entire share count .

At a $240 billion market cap, Marvell would rank approximately 40th in the S&P 500—above companies like Nike ($150B), Starbucks ($110B), and Lockheed Martin ($130B).

**The Estimated Inflows:** If Marvell’s final weight is 0.4% to 0.5% of the index (a reasonable estimate for a top-50 company), passive funds would need to purchase roughly **$30 billion to $37.5 billion** of MRVL stock.

That is a massive, one-time demand shock.

### The Active Fund Effect

Active fund managers who benchmark to the S&P 500 also face pressure to add the stock. If they do not, they risk underperforming the index.

The combination of passive and active demand creates a “virtuous cycle” for newly added stocks: prices rise, which increases the weight, which triggers more buying, which raises prices further.

### The Historical Precedent

When Tesla was added to the S&P 500 in December 2020, the stock had already rallied 700% that year. Yet, the addition itself triggered a further 20% rally over the following weeks.

When Broadcom was added in 2018, the effect was more muted—but Broadcom was already a massive company with a large float. Marvell is joining at a much earlier stage of its growth trajectory.

| Event | Date | Stock Performance (Following Months) |

| :--- | :--- | :--- |

| **Tesla added to S&P 500** | Dec 2020 | +20% |

| **Broadcom added to S&P 500** | 2018 | +10% (moderate) |

| **Marvell addition** | June 22, 2026 | TBD |

## Part 4: The 16% Pullback – A Buying Opportunity?

Here is the twist. On Friday, the same day the S&P addition was announced, Marvell shares fell **16.7%** , dropping from a prior close of $316.43 to as low as $261.39 .

### The Context

The pullback was not company-specific. The entire semiconductor sector was crushed by the one-two punch of a hot jobs report (spiking rate-hike fears) and Broadcom’s “whisper number” disappointment .

Volume surged to 88 million shares—roughly **350% of the average daily volume** . That suggests that large institutions were selling into the S&P addition news, perhaps to lock in profits after a massive run. The stock is up roughly 400% over the past two years.

### The Technical Picture

Despite the sharp drop, the stock remains well above its 50-day moving average of $161.54 and its 200-day moving average of $111.50 .

The RSI (Relative Strength Index) has fallen from overbought levels, suggesting that the selling may have exhausted itself.

### The Valuation Reset

Before the pullback, Marvell was trading at roughly 30x forward earnings . After the 16% drop, that multiple has contracted to roughly 25x.

For a company growing revenue at 42% and earnings at 81%, a 25x multiple is not expensive. The PEG ratio (price/earnings-to-growth) is well under 1—a classic value investing signal.

| Valuation Metric | Before Pullback | After Pullback | Historical Average |

| :--- | :--- | :--- | :--- |

| **Forward P/E** | ~30x | ~25x | ~20x |

| **PEG Ratio** | ~0.8 | ~0.6 | ~1.0 (fair value) |

| **P/S Ratio** | ~12x | ~10x | ~5x |

**The Human Touch:** For the retail investor watching the stock drop 16% on the day of the “good news,” the emotional whiplash is real. The S&P addition is a long-term positive. The 16% drop is a short-term pain. The question is whether you have the conviction to hold through the volatility—or even add to your position.

## Part 5: The Road Ahead – $15 Billion by 2028?

The S&P addition is a milestone, but the investment case for Marvell rests on its execution over the next several years.

### The Third Hyperscaler

The announcement of a **third North American hyperscaler customer** for custom silicon is the most important development . The first two customers are widely believed to be Amazon (Trainium/Inferentia) and Microsoft (Maia). The third could be Google, Meta, or a dark horse like Oracle.

Crucially, Needham reports that this third customer is expected to generate **more revenue than the first two combined** . That suggests that Marvell is winning a larger share of the fastest-growing segment of the AI chip market: custom ASICs.

### The $15 Billion Revenue Target

Marvell believes it can achieve **$15 billion in revenue in the next fiscal year** (fiscal 2028), driven by more than 20 chip designs that will go into production over the next couple of years .

That would represent nearly **double the current $8.2 billion run rate**.

### The ASIC Market Share Opportunity

Counterpoint Research estimates that the AI-focused ASIC market will see a **3x increase in shipments between 2024 and 2027** . Marvell is currently estimated to hold 20-25% of that market, up from less than 5% in 2023 .

Bloomberg notes that Marvell designs custom AI processors for Amazon and Microsoft, and the company is well-positioned to capture business from the other hyperscalers as they seek to reduce their dependence on Nvidia .

| Growth Driver | Current Status | 2028 Target |

| :--- | :--- | :--- |

| **Custom Silicon Customers** | 2 (Amazon, Microsoft) + 1 announced | 4+ hyperscalers |

| **Data Center TAM** | $75 billion | 20% market share goal |

| **Total Revenue** | $8.2 billion (FY2026) | $15 billion (FY2028 target) |

| **AI Revenue** | >$2.5 billion (FY2026 target) | >$5 billion (estimate) |

## Frequently Asked Questions (FAQ)

**Q: When will Marvell join the S&P 500?**

A: Marvell will be added to the S&P 500 effective prior to the open of trading on **Monday, June 22, 2026** .

**Q: Why did Marvell stock drop 16% on the day of the S&P addition announcement?**

A: The drop was part of a broader semiconductor selloff triggered by a hot jobs report (raising rate-hike fears) and Broadcom’s “whisper number” disappointment. Volume surged to 350% of the average, suggesting large institutions were profit-taking after a massive 400% run over two years .

**Q: Is Marvell profitable?**

A: Yes. Marvell has reported positive GAAP earnings in its most recent quarter and cumulatively over the past four quarters, meeting the S&P 500’s strict profitability requirement . This is a key distinction from unprofitable AI companies like SpaceX, OpenAI, and Anthropic, which are not eligible for the index .

**Q: Who are Marvell’s custom silicon customers?**

A: Marvell designs custom AI processors for **Amazon** (Trainium/Inferentia) and **Microsoft** (Maia). The company recently announced a **third North American hyperscaler customer**, expected to generate more revenue than the first two combined .

**Q: How much AI revenue does Marvell expect?**

A: Marvell expects AI revenue to exceed **$2.5 billion in fiscal 2026**, representing 66% year-over-year growth . The company’s total data center revenue target for 2028 is $75 billion TAM, with a goal of 20% market share ($15 billion) .

**Q: Should I buy Marvell stock after the pullback?**

A: (Disclaimer: Not financial advice.) The S&P inclusion creates a floor of passive demand, and the 16% pullback has reset valuations to more reasonable levels (25x forward earnings for 42% revenue growth). However, the semiconductor sector is volatile, and the Fed’s rate-hike fears could pressure the entire market. Long-term investors may see the dip as an opportunity; short-term traders should be aware of continued volatility.

## Conclusion: The Quiet Giant Joins the Club

We started this article with an announcement: Marvell Technology is joining the S&P 500. We end with a recognition that this addition is a milestone for the AI infrastructure era.

Marvell is not the flashiest AI stock. It does not make the headline-grabbing GPUs that power ChatGPT. It does not have a celebrity CEO. But it makes the **networking chips, optical interconnects, and custom ASICs** that hold the AI data centers together.

The S&P 500 nod is a recognition that the “picks and shovels” era of AI has arrived—and it is here to stay.

**For the Index Investor:**

Your S&P 500 fund will automatically add Marvell on June 22. The passive buying will provide a tailwind for the stock.

**For the Active Investor:**

The 16% pullback may be an opportunity. The valuation is reasonable. The growth is accelerating. And the S&P inclusion provides a floor of demand.

**For the Curious:**

Watch the third hyperscaler customer. If it is a major player like Google or Meta, Marvell’s custom silicon business could double again. If it is a smaller player, the growth story is less certain.

**The Bottom Line:**

Marvell passed the profitability test that SpaceX and OpenAI failed. It is joining the most exclusive club in American finance. And it is doing so at a moment when the AI infrastructure buildout is just getting started.

The quiet giant is not quiet anymore.
