what companies are included in tesla stock

Lead

If you searched for "what companies are included in tesla stock", you may mean two different things: which companies Tesla itself owns (subsidiaries and acquisitions), or which external funds, ETFs and institutional portfolios include Tesla stock (TSLA) as a holding. This guide answers both meanings, explains how to check up-to-date holdings, lists notable subsidiaries and major funds that hold TSLA, and gives context on Tesla’s market position as of the reporting date. The phrase "what companies are included in tesla stock" appears repeatedly to make the focus clear and easy to find.

Scope and definitions

In this article we use two distinct senses of the question "what companies are included in tesla stock":

• Company ownership: the companies and teams that Tesla, Inc. has purchased or wholly/partly owns (subsidiaries, acquired startups, and integrated teams).
• Portfolio inclusion: external investment products (ETFs, mutual funds, index funds) and institutional holders that include Tesla stock (TSLA) in their publicly reported portfolios.

Note: corporate ownership and fund holdings change over time. Use official filings and fund holdings pages for current information.

Overview of Tesla, Inc. (TSLA)

Tesla, Inc. is a publicly traded company on NASDAQ under the ticker TSLA. Tesla’s primary business lines are electric vehicles (EVs) and energy products (solar generation and energy storage). The company also invests in software and autonomy (Autopilot, FSD), vehicle manufacturing automation, and new product lines such as Tesla Energy and robotics. Major index inclusions, like the S&P 500, and large institutional ownership mean Tesla is widely held across ETFs and mutual funds.

Because TSLA is both a large-cap public company and a major component in many sector and index funds, the question "what companies are included in tesla stock" can refer to either the businesses under Tesla’s corporate umbrella or the external funds that hold Tesla shares.

Companies owned by Tesla (subsidiaries and notable acquisitions)

When people ask "what companies are included in tesla stock" in the sense of corporate ownership, they want to know what firms Tesla has acquired or owns as subsidiaries. Tesla has acquired a range of companies to build battery competence, manufacturing automation, autonomous driving capabilities, and solar technology. The list below is illustrative, not exhaustive, and reflects acquisitions and subsidiaries commonly referenced in public sources.

Major acquisitions and subsidiaries

SolarCity

SolarCity was acquired by Tesla in 2016 and became the core of Tesla’s energy generation and services business (solar panels and Solar Roof products). The integration combined Tesla’s storage offerings with SolarCity’s installation and solar product capabilities.

Grohmann Engineering (Tesla Grohmann Automation)

Acquired to strengthen automated manufacturing capabilities, Grohmann Engineering — rebranded as Tesla Grohmann Automation — focuses on high-speed automated production equipment to scale vehicle manufacturing.

Maxwell Technologies

Tesla acquired Maxwell Technologies primarily for battery-technology assets and capacitor expertise. Elements of Maxwell’s technology were investigated for integration into Tesla’s battery and cell development programs; some technology has been folded into Tesla’s in-house programs.

Hibar Systems

Hibar Systems is a firm with battery-manufacturing expertise; its assets and know-how have been used to support Tesla’s ambitions for advanced cell production and battery assembly tooling.

DeepScale

DeepScale, a small computer-vision and deep-learning startup, was acquired to augment Tesla’s Autopilot and vision stack. The acquisition supplied machine learning expertise focused on efficient neural networks for automotive perception.

Perbix Machine Company

Perbix, an industrial automation supplier, was bought to strengthen on-site automated manufacturing operations and produce specialized production machinery for Tesla factories.

Other smaller or strategic acquisitions

Tesla has acquired or integrated many smaller teams and firms (including battery startups, automation groups and software teams) to support its battery, manufacturing, and autonomy goals. Examples commonly cited in public reports include SilLion, Springpower, ATW Automation and other specialized engineering or battery-focused firms. Many of these acquisitions were technology or talent purchases that were absorbed into Tesla’s internal programs rather than operated as fully independent public subsidiaries.

Notes on legal structure and subsidiaries

Not every acquisition remains a standalone legal entity. Tesla’s approach has often been to integrate acquired teams or technologies into Tesla’s existing business units (for example, into Tesla Energy or into vehicle manufacturing divisions). Some purchases are held as wholly-owned subsidiaries for regulatory or operational reasons, while others are fully integrated and operate without public-facing branding.

Companies that include Tesla stock (where TSLA appears as a holding)

Another common interpretation of "what companies are included in tesla stock" is asking which funds, ETFs, mutual funds or institutional portfolios include TSLA as a holding. Because Tesla is a large-cap, high-volume stock, it is included in many funds and indexes. Below are categories and examples to illustrate how and where Tesla appears as a holding.

ETFs and funds with notable Tesla exposure

Hundreds of ETFs and mutual funds hold Tesla shares. These range from broad-market index funds to sector-specific ETFs and concentrated thematic funds. Examples (representative categories) include:

• Concentrated thematic ETFs — funds with large allocations to innovation or autonomous/AI/EV themes often hold material TSLA positions (for example, innovation or autonomous-vehicle focused funds).
• Consumer discretionary and sector ETFs — because Tesla is classified in many indices as consumer discretionary or automotive, sector ETFs that track consumer discretionary sectors commonly include Tesla among their top holdings.
• Large-cap index ETFs and mutual funds — funds that track broad U.S. large-cap indexes (S&P 500 or total market funds) include Tesla with a weight proportional to its market capitalization within the index.

Representative named funds often cited in public ETF trackers and reporting include large innovation-focused ETFs and major sector funds; daily-updated holdings services (ETF providers’ pages, ETF tracking sites) show specific weightings and ranks for TSLA in each fund.

How funds weight Tesla (examples and implications)

Weighting of Tesla varies widely by fund type. In broad-market index funds, Tesla’s weight can be a single-digit percentage depending on its market cap relative to the index. In concentrated thematic ETFs, Tesla can represent a large share of the fund (sometimes top-5 or top-3 holding). The implication: owning a broad S&P 500 ETF gives you modest exposure to TSLA, while owning a concentrated innovation ETF can mean substantial exposure.

Indices that include Tesla

Tesla was added to major indices (including the S&P 500) in late 2020, which increased its presence across index-tracking ETFs and mutual funds. Inclusion in widely tracked indices drives institutional and passive fund ownership because ETFs and index funds that track those indices are forced to buy the component stocks in proportion to index weights.

Major institutional and insider holders of Tesla

Institutional ownership of TSLA is significant and is reported in public filings and market-data pages. Major institutional holders commonly include large asset managers and index fund providers, which hold Tesla shares for many client funds.

Major institutional holders (examples)

Principal institutional holders frequently reported in filings and market-data summaries include large asset managers such as Vanguard Group, BlackRock, and State Street. These institutions typically show up near the top of ownership lists because they manage broad index funds and ETFs that hold TSLA. Exact positions and percentages change with quarterly filings and fund rebalancing.

Insider ownership and management stakes

Insider ownership (executives, board members and early investors) is disclosed via SEC filings (Forms 4, 13D/G). Company executives, including the CEO and some early stakeholders, may hold substantial equity positions. Insider holdings and changes are public and provide governance context, though they should not be interpreted as investment advice.

How to find up-to-date information

For authoritative, current data on "what companies are included in tesla stock" (both corporate ownership and who holds TSLA), consult these sources:

• Tesla Investor Relations and SEC filings (10-K, 10-Q, Forms 4 and 13D/G) for corporate structure, subsidiary details and insider transactions.
• ETF providers’ daily holdings pages and fund prospectuses for current ETF and mutual fund holdings and weightings (search the fund name on its official site; many provide CSV or PDF daily holdings).
• ETF tracking sites and fund-data providers that list ETFs containing TSLA and show weightings (these are useful but should be cross-checked against provider pages).
• EDGAR (SEC) for institutional 13-F filings that list quarterly holdings by large managers (useful to see which institutions held TSLA at quarter end).
• Market-data pages (financial news and stock quote pages) for high-level summaries of major holders, market cap and key statistics.

When checking fund or ETF holdings pages, use official fund pages for the single source of truth. For a trader-friendly way to access markets and ETFs that hold TSLA, consider trading and wallet services that list ETF holdings and support direct market access; for on-ramp and custody, Bitget and Bitget Wallet offer tools for investors interested in spot trading and asset custody.

Common misunderstandings and clarifications

Below are common confusions around the question "what companies are included in tesla stock":

• TSLA is the ticker for Tesla, Inc. — it does not literally "include" other independent public companies under that ticker. Corporate acquisitions owned by Tesla are separate legal entities or integrated operations; they are not listed under TSLA as separate tickers.
• When people ask "what companies are included in tesla stock", confirm which meaning they intend: corporate subsidiaries vs. which funds include TSLA.
• Holdings and ownership percentages change frequently. Institutional holdings are reported quarterly; ETF holdings can update daily. Verify via primary sources before making decisions.

Historical notes and notable transactions

Key transactions and integration milestones that often come up when discussing "what companies are included in tesla stock" include Tesla’s acquisition of SolarCity (2016), the purchases of Grohmann Engineering, Maxwell Technologies and smaller battery/automation startups. These moves supported Tesla’s vertical integration strategy: combining vehicle production, cell and pack development, manufacturing automation and energy products under Tesla’s corporate umbrella.

Another important milestone was Tesla’s inclusion in the S&P 500 in late 2020, which materially increased passive ownership of TSLA across index funds and ETFs.

Recent market context (reporting date and note)

As of 2025-12-30, according to the provided news excerpt about the "Magnificent Seven", Tesla remains one of the largest and most influential U.S. stocks by market capitalization. The excerpt reports a market-cap figure and trading data that illustrate Tesla’s scale (for example, a market cap around $1.6 trillion and active daily trading volumes noted in the excerpt). This context helps explain why many funds and ETFs include TSLA: large market-cap stocks naturally attract inclusion in broad and sector-specific funds.

The same news excerpt discussed evolving investor preferences around AI and chipmakers (e.g., Taiwan Semiconductor, Broadcom) and noted that some managers rebalanced the traditional "Magnificent Seven". That reporting underscores how fund managers’ thematic focus can change the relative weight of Tesla in different concentrated funds, even while Tesla remains widely held in index funds.

Practical checklist — how to verify "what companies are included in tesla stock" for your purpose

1. Decide which meaning you need: corporate ownership (subsidiaries) or portfolio inclusion (which funds hold TSLA).
2. For subsidiaries: review Tesla’s SEC filings and annual report (10-K) and Tesla’s investor relations materials for lists of material subsidiaries and acquisitions.
3. For fund holdings: view the ETF or mutual fund’s daily holdings page or prospectus. Use the fund provider’s official site as primary source.
4. For institutional ownership: check 13-F filings on EDGAR and market-data summaries that list the top institutional holders as of the most recent quarter.
5. If you trade or hold TSLA, use a trusted trading venue (for crypto/web3 and spot markets, consider Bitget) and a secure wallet for custody (Bitget Wallet recommended for Web3 assets). Always confirm holdings across the original issuer or fund pages before acting.
