Investment Risks - Putnam Focused U.S. Research ETF	Feb. 28, 2026
Common stock risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Common stock risk: Common stock represents an ownership interest in a company. The value of a company’s stock may fall or fail to rise as a result of factors directly relating to that company, such as decisions made by its management or lower demand for the company’s products or services. A stock’s value may also fall because of factors affecting not just the company, but also other companies in the same industry or in a number of different industries, such as increases in production costs. Companies whose stocks the Investment Manager believes are undervalued by the market may have experienced adverse business developments or may be subject to special risks that have caused their stocks to be out of favor. Growth stocks may be more susceptible to earnings disappointments, and value stocks may fail to rebound. The fund will be more susceptible to these risks than other funds because it concentrates its investments in a limited number of issuers or sectors, and the fund may perform poorly as a result of adverse developments affecting those issuers or sectors. These risks are generally greater for small and midsize companies.
Industry or sector concentration risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Industry or sector concentration risk: From time to time, the fund may invest a significant portion of its assets in companies in one or more related industries or sectors, which would make the fund more vulnerable to adverse developments affecting those industries or sectors. For example, the fund may invest a significant portion of its assets in companies in the information technology sector that may be significantly affected by technological obsolescence or innovation, short product cycles, falling prices and profits, competitive pressures and general market conditions.
Large shareholder transaction risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Large shareholder transaction risk: The fund is subject to the risk that shareholders will purchase or redeem large quantities of shares of the fund. The fund may be an investment option for mutual funds that are managed by the Investment Manager and its affiliates as “funds of funds.” Additionally, other investors from time to time may make substantial investments in the fund. Such shareholders may at times be considered to control the fund. In addition, a large number of shareholders may collectively purchase or redeem fund shares in large amounts rapidly or unexpectedly. Large shareholder transactions may adversely affect the fund’s liquidity and net assets. These redemptions may also adversely affect the fund’s performance if the fund is forced to sell securities, which may also increase the fund’s brokerage costs.
Cybersecurity risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Cybersecurity risk: Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to fund assets, fund or customer data (including private shareholder information), or proprietary information, cause the fund, the Investment Manager, authorized participants and listing exchanges and/or their service providers (including, but not limited to, fund accountants, custodians, sub‑custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent fund investors from purchasing or redeeming shares or receiving distributions. The fund and the Investment Manager have limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the fund and/or the Investment Manager. Cybersecurity incidents may result in financial losses to the fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents. Because technology continues to evolve rapidly, including through developments in artificial intelligence and machine learning, new methods of carrying out cyber-attacks continue to emerge. As a result, certain cybersecurity risks may not yet be identified and some cyber-attacks may not be detected promptly, which may limit the fund’s ability to anticipate, prepare for or respond effectively to a cybersecurity incident. Like other funds and business enterprises, the fund, the Investment Manager and their service providers are subject to the risk of cybersecurity incidents from time to time. The rapid development and increasingly widespread use of artificial intelligence technologies may increase the sophistication and effectiveness of cyber attacks, which may exacerbate these risks.
Management and operational risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Management and operational risk: There is no guarantee that the investment techniques, analyses, or judgments that the Investment Manager applies in making investment decisions for the fund will produce the intended outcome or that the investments selected for the fund will perform as well as other securities that were not selected for the fund. The Investment Manager, or the fund’s other service providers, may experience disruptions or operating errors that could negatively impact the fund. The fund may not achieve its goal, and it is not intended to be a complete investment program. An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Fluctuation of net asset value and share price risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Fluctuation of net asset value and share price risk: Shares may trade at a larger premium or discount to the fund’s net asset value than shares of other ETFs. The net asset value of the fund will generally fluctuate with changes in the market value of the fund’s holdings. The fund’s shares can be bought and sold in the secondary market at market prices. Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for the fund’s shares may result in the fund’s shares trading significantly above (at a premium) or below (at a discount) net asset value or the intraday value of the fund’s holdings. In addition, in stressed market conditions or periods of market disruption or volatility, the market for fund shares may become less liquid in response to deteriorating liquidity in the markets for the fund’s underlying portfolio holdings.
Trading issues risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Trading issues risk: The fund has no public trading history. There can be no assurance that an active trading market will develop or be maintained or that the market for fund shares will operate as intended, which could lead to the fund’s shares trading at wider spreads and larger premiums and discounts to net asset value than other actively managed ETFs. As a result, it may cost investors more to trade fund shares than shares of other ETFs. There is no guarantee that the fund will be able to attract market makers and authorized participants. Market makers and authorized participants are not obligated to make a market in the fund’s shares or to submit purchase and redemption orders for creation units. The market prices of the fund’s shares are expected to fluctuate, in some cases materially, in response to changes in the fund’s net asset value, the intraday value of the fund’s holdings and supply and demand for the fund’s shares. The Investment Manager cannot predict whether the fund’s shares will trade above, below or at their net asset value or the intraday value of the fund’s holdings. During periods when the fund is trading below its net asset value, investors may incur significant losses if they sell shares. The securities held by the fund may be traded in markets that close at a different time than the exchange on which the fund’s shares are listed. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the exchange is open but after the applicable market closing, fixing or settlement times, bid‑ask spreads on the exchange and the corresponding premium or discount to the shares’ net asset value may widen.
Authorized participant concentration risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Authorized participant concentration risk: Only an authorized participant may engage in creation and redemption transactions directly with the fund. The fund may have a limited number of financial institutions that act as authorized participants, none of which are obligated to engage in creation and/or redemption transactions. To the extent that those authorized participants do not engage in creation and redemption orders, there may be a significantly diminished trading market for fund shares or fund shares may trade at a discount (or premium) to net asset value and possibly face trading halts and/or delisting.
Market risks [Member]
Prospectus [Line Items]
Risk [Text Block]	Market risk: The value of investments in the fund’s portfolio may fall or fail to rise over extended periods of time for a variety of reasons, including general economic, political or financial market conditions, investor sentiment and market perceptions, government actions, geopolitical events or changes, outbreaks of infectious illnesses or other widespread public health issues, and factors related to a specific issuer, asset class, geography, industry or sector. These and other factors may lead to increased volatility and reduced liquidity in the fund’s portfolio holdings, may negatively impact the fund’s performance, and may exacerbate other risks to which the fund is subject.
Risk Lose Money [Member]

Risk [Text Block]	It is important to understand that you can lose money by investing in the fund.
Risk Not Insured Depository Institution [Member]
Prospectus [Line Items]
Risk [Text Block]	An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Risk Nondiversified Status [Member]
Prospectus [Line Items]
Risk [Text Block]	Non‑diversified risk: As a non‑diversified fund, the fund invests in fewer issuers and is more vulnerable than a more broadly diversified fund to fluctuations in the values of the securities it holds. Moreover, the gains and losses on a single investment may have a greater impact on the fund’s net asset value and may make the fund more volatile than more diversified funds.
