Will ETH See Fund Inflows Again? Sharplink and BitMine Make It onto the Russell Index List

Abstract

Two Ethereum (ETH)-related public companies, Sharplink (SBET) and BitMine (BMNR), will be added to the U.S. Russell Indexes on June 29, 2026. SBET is confirmed for the Russell 2000 and Russell 3000, while BMNR is on the preliminary list for the Russell 3000 and has a high chance of entering the Russell 1000. This inclusion acts as an "automatic shopping list" for massive passive investment funds like ETFs and pension plans, compelling them to buy these stocks to match the index composition. Consequently, millions of mainstream investors who do not directly trade crypto will automatically gain exposure to these Ethereum-linked equities through their index funds. This move channels significant passive capital—trillions of dollars track these indexes—into SBET and BMNR, integrating Ethereum-related investment opportunities into traditional financial portfolios. While the funds buy the companies' stocks, not ETH directly, this is expected to provide short-term price support for the stocks and increase their liquidity and institutional ownership. Over the long term, it could also indirectly incentivize the companies to acquire more ETH.

Author: Lanhu Notes

Two publicly listed companies related to Ethereum (ETH)—Sharplink (SBET) and BitMine (BMNR)—will officially be added to the U.S. Russell Indexes at the market open on June 29, 2026.

The current situation is:

  • SBET (Sharplink) is confirmed to join the Russell 2000 (small-cap index) and the Russell 3000.
  • BMNR (BitMine) is on the preliminary list and is expected to join the Russell 3000, with a high probability of also entering the Russell 1000 (large-cap index).

How to understand this?

Imagine the U.S. has a massive passive investment "automatic shopping system"—such as passive index funds, ETFs, pension funds, 401k plans, etc.

They don't pick stocks themselves; instead, they automatically buy exactly which companies and in what proportions are listed in the Russell Indexes.

SBET and BMNR being added to these lists is equivalent to:

Opening the "floodgates of passive capital" for SBET and BMNR, allowing millions of ordinary investors who don't trade cryptocurrencies or understand Ethereum to automatically hold them. This effectively pushes Ethereum opportunities into the mainstream channels of traditional finance.

Specifically,

The amount of capital tracking the Russell 2000 and Russell 3000 globally is enormous (on the scale of trillions of dollars).

Once officially included, these funds must purchase the corresponding stocks to match the index.

Previously, only investors actively researching crypto would buy these stocks.

Now, after entering the index, the money from mainstream investors (including a large number of retail and institutional investors) who "don't bother picking stocks and only buy index funds" will also automatically flow into SBET and BMNR.

This naturally integrates Ethereum-related investment opportunities into mainstream U.S. traditional financial portfolios.

The buying by passive funds creates real demand, especially around the inclusion生效 date, often providing short-term support for the stock price (the so-called "index inclusion effect").

In the long term, it also enhances stock liquidity and institutional ownership (for many established companies, passive ownership can reach 20-25% or more).

It's important to note that passive funds are buying SBET and BMNR stocks, not ETH. To match the index, funds must buy these two stocks; they won't go directly to an exchange to buy ETH. However, this will indirectly encourage the companies to buy more ETH.

Related Questions

QWhich two Ethereum-related public companies are set to be added to the US Russell indexes, and when does the addition take effect?

AThe two companies are Sharplink (SBET) and BitMine (BMNR). They are scheduled to be officially added to the Russell indexes at the US market open on June 29, 2026.

QWhat is the significance of a company being added to the Russell indexes in terms of capital inflows?

AInclusion in the Russell indexes opens the 'floodgates of passive capital.' Passive investment vehicles like index funds, ETFs, and pension funds that track these indexes are mandated to automatically buy the stock, channeling billions from mainstream traditional investors who may not otherwise invest in crypto-related assets into these companies.

QInto which specific Russell indexes are Sharplink (SBET) and BitMine (BMNR) being added?

ASharplink (SBET) is confirmed for addition to the Russell 2000 and Russell 3000 indexes. BitMine (BMNR) is on the preliminary list for the Russell 3000 and has a high probability of also entering the Russell 1000 index.

QDoes the direct purchase of these companies' stock by passive funds equate to a direct purchase of Ethereum (ETH)?

ANo, it does not. Passive funds buying SBET and BMNR stock is a direct purchase of the company's equity to match the index composition. It is not a direct purchase of Ethereum (ETH) on cryptocurrency exchanges. However, the article suggests this capital inflow could indirectly encourage the companies themselves to acquire more ETH.

QWhat are the potential market effects, both short-term and long-term, of a stock's inclusion in a major index like the Russell?

AShort-term, inclusion often creates buying pressure around the effective date, providing price support (the 'index inclusion effect'). Long-term, it increases the stock's liquidity and raises its institutional ownership percentage, as passive funds typically hold their positions, with mature companies often having 20-25%+ passive ownership.

After Marvell's 32% Surge, the Chinese Chip Family Behind It Emerges

The stock price of Marvell Technology surged 32.5% on June 2nd, driven by NVIDIA CEO Jensen Huang highlighting its custom ASICs and optical interconnects as core to AI data center architecture. This event brought attention to the Chinese semiconductor family behind Marvell: the Dai siblings. The story centers on three siblings, all UC Berkeley graduates, whose three-decade entrepreneurial journey aligns with major semiconductor industry shifts. In 1995, youngest sister Dai Wei Li co-founded Marvell with her husband Sehat Sutardja and his brother, focusing on storage controllers. Eldest brother Dai Wei Min founded EDA company Ultima, later sold to Cadence, and later founded VeriSilicon (芯原) in China, becoming a leading semiconductor IP provider. Second brother Dai Wei Jin co-founded EDA firm Silicon Perspective (sold to Cadence) and GPU IP company Vivante, later acquired by VeriSilicon. The combined "Dai-Sutardja" family network extends beyond Marvell. Their ventures and investments form a comprehensive ecosystem for the post-Moore's Law, chiplet era. Key holdings include: Dream Big Semiconductor (AI SuperNICs, acquired by Arm), Alphawave (high-speed SerDes IP, acquired by Qualcomm), and Silicon Box (a chiplet advanced packaging foundry). VeriSilicon itself thrives on the AI ASIC and IP boom in China. Collectively, the family's AI infrastructure-related portfolio is estimated at over $22 billion. Their strategy represents a distinct path: building critical components for open standards and key manufacturing capacity in the chiplet era, rather than pursuing standalone AI chip dominance. While this path may not create the next NVIDIA, it has enabled repeated successful exits and sustained influence within the global semiconductor industry.

Microsoft is Afraid of Being Marginalized by AI Giants

Microsoft, once the defining force of the PC era, now faces a familiar challenge in the AI age: the risk of being relegated to a profitable but invisible infrastructure provider. This anxiety was laid bare at Build 2026, where CEO Satya Nadella unveiled a major strategic pivot. The catalyst was a quiet April agreement that dissolved Microsoft's exclusive licensing and cloud-hosting deal with OpenAI, its once-vital partner. This erased Microsoft's key AI moat. With OpenAI and Anthropic defining AI applications and gaining enterprise traction—even within Microsoft's own ranks—Nadella had to answer: without exclusivity, what is Microsoft's role? The answer was a suite of seven in-house AI models, a developer-focused AI workstation (Surface RTX Spark Dev Box), and, most crucially, the Agent 365 platform for enterprise AI governance. The models, notably targeting Anthropic's strengths in coding and enterprise, signal a defensive move. However, the broader strategy is to make the models themselves less decisive. Financially, Microsoft's AI revenue is strong, driven largely by Azure running others' models. Yet its user-facing products like Copilot show weak penetration and engagement. Microsoft earns infrastructure money but lacks direct user mindshare. Nadella's core fear is being "hollowed out." As OpenAI and Anthropic prepare for IPOs and gain financial independence, they may build their own infrastructure, threatening Azure's lucrative AI revenue stream. Microsoft's window is to entrench itself deeper: not as the model creator, but as the indispensable platform for securely deploying, managing, and governing all AI models within the enterprise through Agent 365. Build 2026 revealed Microsoft's bet: in the AI era, the ultimate power lies not in any single model, but in the enterprise "operating system" that controls them. Nadella is determined to ensure Microsoft is the driver of this new era, not just a passenger.

US Stocks Surge 16% in Two Months: Only 4 Occurrences in History, the Most Recent Was Just Before the 1987 Crash

U.S. stocks have surged 16% over April and May, a gain seen only four times since WWII, according to Deutsche Bank strategist Henry Allen. Three prior instances followed recessions, but the sole non-recession precedent was in early 1987, months before the "Black Monday" crash. The current rally is underpinned by AI enthusiasm and strong data, but its speed without an economic recovery is historically unprecedented. Meanwhile, credit spreads remain near record lows despite growing consumer strain—the U.S. savings rate hit just 2.6% in April, a level last seen before the Global Financial Crisis, and consumer sentiment is at its lowest since 1952. Market risks are concentrated. While stocks and credit markets appear immune to geopolitical tensions, sovereign bonds tell a different story. Treasury yields have tracked oil prices and recently hit multi-year highs, creating a widening divergence with equities. Surprisingly stable oil prices, despite the prolonged closure of the Strait of Hormuz, have been a key pillar for risk assets. However, if the blockage persists, this support could fade, raising the risk of a stagflation shock not currently priced in.

CPU, Quietly Returning to the Center of the AI Computing Power Stage

Over the past three years, AI computing power narratives have been dominated by GPUs. However, starting in 2026, this story began to shift. While training large models remains GPU-intensive, the rapid growth of inference and AI agent workloads, which require high levels of task orchestration, concurrency, and data flow management, has highlighted a renewed critical role for CPUs. These are tasks GPUs are not designed to handle. Intel's recent launch of the Xeon 6+ processor, built on its Intel 18A process and featuring up to 288 efficiency cores (E-cores), exemplifies this strategic pivot. It is positioned not as a mere companion to GPUs but as the essential "control plane" for AI infrastructure, optimized for high-density, energy-efficient, and high-throughput workloads characteristic of AI agents and inference. This "CPU resurgence" is not about CPUs outperforming GPUs in raw computation. It reflects a systemic bottleneck: as AI scales from training single models to deploying countless intelligent agents, the demand for coordination and data handling surges. Major cloud providers are also developing their own high-density ARM-based server CPUs for similar workloads. However, Intel's success with this strategy faces significant challenges. Competition includes NVIDIA's integrated CPU-GPU solutions, the expanding adoption of cloud vendors' in-house ARM CPUs, and the crucial market test of Intel's 18A manufacturing process against rivals like TSMC's N2. In conclusion, CPUs are indeed reclaiming a central, though redefined, role in AI compute—managing the complex orchestration that enables massive-scale AI deployment. While the trend is clear, which company will ultimately lead this CPU resurgence remains an open question to be decided in the data centers of 2027 and beyond.
