The example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. This example does not include brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

| Portfolio Turnover [Text Block] | oef_PortfolioTurnoverTextBlock | The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 17% of the average value of its portfolio.

| Strategy Narrative [Text Block] | oef_StrategyNarrativeTextBlock | The Fund is an index fund that seeks to track the investment results of the Underlying Index..
Strictly in accordance with its guidelines and mandated procedures, Nasdaq, Inc. (“Nasdaq” or the “Index Provider”) compiles the Underlying Index, which is designed to track the performance of companies engaged in Internet-related businesses that are listed on the New York Stock Exchange (“NYSE”), NYSE American, Cboe BZX Exchange (“Cboe”) or The Nasdaq Stock Market®. Companies in the Underlying Index include companies whose primary business includes Internet-related services including, but not limited to, Internet software, Internet search engines, web hosting, website design or Internet retail commerce as determined by the Consumer Technology Association (“CTA”). The Underlying Index may include common stocks, ordinary shares, American depositary receipts (“ADRs”), shares of beneficial interest or limited partnership interests and tracking stocks.
As of June 30, 2026, the Underlying Index was comprised of 77 constituents with market capitalizations ranging from $173 million to $4.3 trillion.
The Fund employs a “full replication” methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index. The Fund is “non-diversified” and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”). In accordance with Rule 35d-1 under the 1940 Act, the Fund has adopted a policy to invest, under normal circumstances, at least 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, in the components of the Underlying Index and in derivatives and other investments that have economic characteristics similar to the components of the Underlying Index (the “80% investment policy”).
Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries. As of April 30, 2026, the Fund had significant exposure to the internet-related services industry and the communication services, information technology, and consumer discretionary sectors. The Fund’s portfolio holdings, and the extent to which it concentrates its investments, are likely to change over time.

| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Additionally, natural or environmental disasters, widespread disease or other public health issues, war, military conflicts, acts of terrorism, economic crises or other events could result in increased premiums or discounts to the Fund’s net asset value (“NAV”). Certain changes in the U.S. economy in particular, such as when the U.S. economy weakens or when its financial markets decline, may have a material adverse effect on global financial markets as a whole, and on the securities to which the Underlying Index has exposure. Increasingly strained relations between the U.S. and foreign countries, including as a result of economic sanctions and tariffs, may also adversely affect U.S. issuers, as well as non-U.S. issuers.
During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Underlying Index will rise in value.

Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, the Fund would not necessarily buy or sell a security unless that security is added to or removed from, respectively, its Underlying Index, even if that security generally is underperforming. Additionally, the Fund generally rebalances its portfolio in accordance with its Underlying Index, and, therefore, any changes to its Underlying Index’s rebalance schedule will typically result in corresponding changes to the Fund’s rebalance schedule.

| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Industry Concentration Risk. In following its methodology, the Underlying Index will be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. As a result, the Fund will also concentrate its investments in such industries or industry groups to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund faces more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources; adverse labor relations; political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or industry group may be out of favor and underperform other industries or the market as a whole.

| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Internet-Related Services Industry Risk. Internet companies are subject to rapid changes in technology, hacking or other cybersecurity events, worldwide competition, rapid obsolescence of products and services, loss of patent protections, cyclical market patterns, evolving industry standards, frequent new product introductions, and the risk of owning companies that have recently begun operations. Competitive pressures, such as technological developments, fixed-rate pricing and the ability to attract and retain skilled employees, can significantly affect internet companies, and changing domestic and international demand, research and development costs, availability and price components and product obsolescence also can affect their profitability. The widespread adoption of new internet, networking, telecommunications technologies, or other technological changes could require substantial expenditures by an internet company to modify or adapt its services or infrastructure, which could have a material adverse effect on an internet company's business. Prices of securities of companies in this industry tend to be more volatile than securities of companies in other industries, and may fluctuate widely due to general economic conditions, consumer spending and the availability of disposable income, changing consumer tastes and preferences and consumer demographics. Legislative or regulatory changes and increased government supervision also may affect companies in this industry.

| Risk [Text Block] | oef_RiskTextBlock | Communication Services Sector Risk. The value of the securities of communication services companies are particularly vulnerable to rapid advancements in technology, the innovation of competitors, rapid product obsolescence, and government regulation and competition, both domestically and internationally. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company’s profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses. Communication services companies also rely on the use of intellectual property such as patents, copyrights and trademarks owned internationally or licensed through third parties.

| Risk [Text Block] | oef_RiskTextBlock | Information Technology Sector Risk. Information technology companies are subject to intense competition, and their products are at risk of rapid obsolescence, which make the prices of securities issued by these companies particularly volatile. Product obsolescence can result from rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Factors that may also significantly affect the market value of securities of issuers in the information technology sector include the failure to obtain, or delays in obtaining, financing or regulatory approval, product incompatibility, changing consumer preferences, increased government scrutiny, high required corporate capital expenditure for research and development or infrastructure and development of new products, and competition from alternative technologies. Information technology companies are also heavily dependent on patent and other intellectual property rights, and the loss or impairment of these rights may adversely affect the company's profitability.

| Risk [Text Block] | oef_RiskTextBlock | Consumer Discretionary Sector Risk. Companies engaged in the consumer discretionary sector are affected by fluctuations in supply and demand, and changes in consumer preferences, social trends and marketing campaigns. Changes in consumer spending as a result of world events, political and economic conditions, commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources and labor relations also may adversely affect these companies.

| Risk [Text Block] | oef_RiskTextBlock |
Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in the obligations or securities of a small number of issuers or any single issuer than a diversified fund can. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance.

| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Equity Risk. Equity risk is the risk that the value of equity securities, including common stocks, may fall due to both changes in general economic conditions that impact the market as a whole, as well as factors that directly relate to a specific company or its industry. Such general economic conditions include changes in interest rates, periods of market turbulence or instability, or general and prolonged periods of economic decline and cyclical change. It is possible that a drop in the stock market may depress the price of most or all of the common stocks that the Fund holds. In addition, equity risk includes the risk that investor sentiment toward one or more industries will become negative, resulting in those investors exiting their investments in those industries, which could cause a reduction in the value of companies in those industries more broadly. Equity risk also includes the risk of large-capitalization companies, which may adapt more slowly to new competitive challenges or may be more mature and subject to more limited growth potential, and consequently may underperform other segments of the equity market or the market as a whole. The value of a company's common stock may fall solely because of factors, such as an increase in production costs, that negatively impact other companies in the same region, industry or sector of the market. A company's common stock also may decline significantly in price over a short period of time due to factors specific to that company, including decisions made by its management or lower demand for the company's products or services. For example, an adverse event, such as an unfavorable earnings report or the failure to make anticipated dividend payments, may depress the value of common stock.

| Risk [Text Block] | oef_RiskTextBlock |
Small- and Mid-Capitalization Companies Risk. Investing in securities of small- and mid-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. Stocks of small- and mid-capitalization companies tend to be more vulnerable to changing market conditions, may have little or no operating history or track record of success, and may have more limited product lines and markets, less experienced management and fewer financial resources than larger companies. These companies’ securities may be more volatile and less liquid than those of more established companies. They may be more sensitive to changes in a company’s earnings expectations and may experience more abrupt and erratic price movements. Smaller companies’ securities often trade in lower volumes and in many instances, are traded over-the-counter or on a regional securities exchange, where the frequency and volume of trading is substantially less than is typical for securities of larger companies traded on national securities exchanges. Therefore, the securities of smaller companies may be subject to wider price fluctuations and it might be harder for the Fund to dispose of its holdings at an acceptable price when it wants to sell them. Since small- and mid-capitalization companies typically reinvest a high proportion of their earnings in their business, they may not pay dividends for some time, particularly if they are newer companies. It may take a substantial period of time to realize a gain on an investment in a small- or mid-capitalization company, if any gain is realized at all.

| Risk [Text Block] | oef_RiskTextBlock | ADR Risk. ADRs are certificates that evidence ownership of shares of a foreign issuer and are alternatives to purchasing the underlying foreign securities directly in their national markets and currencies. ADRs may be subject to certain of the risks associated with direct investments in the securities of foreign companies, such as currency, political, economic and market risks, because their values depend on the performance of the non-dollar denominated underlying foreign securities. Moreover, ADRs may not track the price of the underlying foreign securities on which they are based, and their value may change materially at times when U.S. markets are not open for trading.

| Risk [Text Block] | oef_RiskTextBlock | Issuer-Specific Changes Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform worse than the market as a whole, causing the value of the Fund’s securities to decline.

| Invesco NASDAQ Internet ETF | Invesco NASDAQ Internet ETF | Valuation Risk [Member] | ||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Valuation Risk. The price the Fund could receive upon the sale of a portfolio investment may differ from the Fund’s valuation of the investment, particularly for investments that trade in thin or volatile markets or that are valued using a fair valuation methodology. Fixed income securities are often valued assuming orderly transactions of institutional round lot size, but the Fund may hold or transact in the same securities in smaller, odd lot sizes. Odd lots often trade at lower prices than institutional round lots. Financial information related to securities of non-U.S. issuers may be less reliable than information related to securities of U.S. issuers, which may make it difficult to obtain a current price for a non-U.S. security held by the Fund. When market quotations are not readily available or deemed non-representative of fair value for Fund investments, those investments are fair valued by the Adviser. There are multiple methods that can be used to fair value a portfolio investment and such methods may involve more subjectivity than the use of market quotations. The value established for an investment through fair valuation may be different from what would be produced if the investment had been valued using market quotations. In addition, there is no assurance that the Fund could sell a portfolio investment at any time for the value ascribed to it for purposes of calculating the Fund’s net asset value, and it is possible that the Fund could incur a loss because an investment is sold at a discount to its ascribed value. The ability to value investments may also be impacted by technological issues and/or errors by pricing services or other third-party service providers.

| Risk [Text Block] | oef_RiskTextBlock | Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, and Shares may be more likely to trade at a premium or discount to the Fund's NAV and to face trading halts and/or delisting. Additionally, to the extent that the Fund holds non-U.S. securities, such securities may have lower trading volumes or could experience extended market closures or trading halts. To the extent that the Fund invests in non-U.S. securities, it may face increased risks that APs may not be able to effectively create or redeem Creation Units, or that the Shares may be halted and/or delisted.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, periods of high volatility, and disruption in the creation/redemption process of the Fund. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s portfolio holdings, which may cause a variance in the market price of Shares and their underlying NAV. In addition, an exchange or market may issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation/redemption process, potentially affect the price at which Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's NAV.

The Fund and its investment adviser, Invesco Capital Management LLC (the “Adviser”), seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

| Risk [Text Block] | oef_RiskTextBlock | Shares May Trade at Prices Different than NAV. Shares trade on a stock exchange at prices at, above or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result, the trading prices of the Shares may deviate from the Fund’s NAV. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.
