Investment Objective

The WisdomTree Barclays Negative Duration U.S. Aggregate Bond Fund (the “Fund”) seeks to track the price and yield performance, before fees and expenses, of the Bloomberg Barclays Rate Hedged U.S. Aggregate Bond Index, Negative Five Duration (the “Index”).

Fees and Expenses of the Fund

The following table describes the fees and expenses you may pay if you buy and hold shares of the Fund. The fees are expressed as a percentage of the Fund’s average net assets.

Shareholder Fees (fees paid directly from your investment)	None
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees	0.28%
Distribution and/or Service (12b-1) Fees	None
Other Expenses	0.00%
Total Annual Fund Operating Expenses	0.28%

Example

The following example is intended to help retail investors compare the cost of investing in the Fund with the cost of investing in other funds. It illustrates the hypothetical expenses that such investors would incur over various periods if they were to invest $10,000 in the Fund for the time periods indicated and then redeem all of the shares at the end of those periods. This example assumes that the Fund provides a return of 5% a year and that operating expenses remain the same. This example does not include the brokerage commissions that retail investors may pay to buy and sell shares of the Fund. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

	1 Year	3 Years	5 Years	10 Years
	$ 29	$ 90	$ 157	$ 356

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 226% of the average value of its portfolio, including TBA Transactions (as defined below), and 56% of the average value of its portfolio (excluding TBA Transactions).

Principal Investment Strategies of the Fund

The Fund employs a “passive management” – or indexing – investment approach designed to track the performance of the Index. The Fund generally uses a representative sampling strategy to achieve its investment objective, meaning it generally will invest in a sample of the securities in the Index whose risk, return and other characteristics resemble the risk, return and other characteristics of the Index as a whole. Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) will be invested in the component securities of the Index and investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities.

The Index is designed to provide long exposure to the Bloomberg Barclays U.S. Aggregate Bond Index while seeking to manage interest rate risk through the use of short positions in U.S. Treasury securities (“U.S. Treasuries”). The Index is comprised of a long portfolio and short portfolio. The “long portfolio” of the Index intends to replicate the Bloomberg Barclays U.S. Aggregate Bond Index, which broadly captures the U.S. investment grade, fixed income securities market and is comprised of U.S. Treasuries and U.S. Government-related bonds (e.g., obligations of the U.S. Government or its agencies or instrumentalities), corporate bonds, mortgage-backed pass-through securities, commercial mortgage-backed securities and asset-backed securities that are publicly offered for sale in the United States. The “short portfolio” of the Index holds short positions in U.S. Treasuries that seek to correspond to a duration exposure exceeding the duration of the long portfolio, with a targeted total duration exposure of approximately negative five years (e.g., if the average duration of bonds in the long portfolio is approximately five years, the short portfolio will seek an average duration of approximately ten years among its short holdings of U.S. Treasuries, with an aggregate targeted duration of Index holdings of approximately negative five years). Duration is a measure used to determine the sensitivity of a portfolio to changes in interest rates with a longer duration portfolio being more sensitive to changes in interest rates.

The Index methodology weights the short exposure to U.S. Treasuries of differing maturities in a manner that is intended to achieve the desired duration target for the Index, while seeking to mitigate the risk to shifts in the Treasury yield curve between the long and short maturity securities of the Index. The short exposure in the Index and the Fund, respectively, is expected to have greater sensitivity to interest rates than the long exposure of the Index and the Fund, respectively, in targeting the desired overall interest rate sensitivity, which has a target duration of negative five years. The short exposure of the Index and Fund are also expected to be more heavily weighted toward longer maturity U.S. Treasuries (or futures providing exposure to U.S. Treasuries in the case of the Fund) than the long exposure. The long portfolio and short portfolio of the Index are rebalanced on a monthly basis to where the dollar amount of the long portfolio’s bond positions is approximately equivalent to the dollar amount of the short exposure achieved within the short portfolio.

The Index is designed to have greater returns than an equivalent non-interest rate hedged investment when U.S. Treasury rates are rising significantly. Conversely, the Index is designed to have lower returns than an equivalent non-interest rate hedged investment when U.S. Treasury rates are falling significantly.

A significant portion of the bonds represented in the long portion of the Index are U.S. agency mortgage-backed pass-through securities. U.S. agency mortgage-backed pass-through securities are securities issued by entities such as Government National Mortgage Association (“GNMA”) and Federal National Mortgage Association (“FNMA”) that are backed by pools of mortgages. Most transactions in mortgage-backed pass-through securities occur through standardized contracts for future delivery in which the exact mortgage pools to be delivered are not specified until a few days prior to settlement, referred to as a “to-be-announced transaction” or “TBA Transaction.” In a TBA Transaction, the buyer and seller agree upon general trade parameters such as agency, settlement date, paramount and price. The actual pools delivered generally are determined two days prior to the settlement date; however, it is not anticipated that the Fund will receive pools, but instead will participate in rolling TBA Transactions. The Fund expects to enter into such contracts on a regular basis. The Fund, pending settlement of such contracts, will invest its assets in high-quality, liquid short term instruments.

In seeking to track the short portfolio of the Index, the Fund will invest in short positions in futures contracts on U.S. Treasuries. The Fund may also short U.S. Treasuries.

To the extent the Index concentrates (i.e., holds 25% or more of its total assets) in the securities of a particular industry or group of industries, the Fund will concentrate its investments to approximately the same extent as its Index.

Principal Risks of Investing in the Fund

You can lose money on your investment in the Fund. The Fund is subject to the risks described below. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return

2  WisdomTree Trust Prospectus

and/or ability to meet its objectives. For more information about the risks of investing in the Fund, see the sections in the Fund’s Prospectus titled “Additional Principal Risk Information About the Funds” and “Additional Non-Principal Risk Information.”

■	Investment Risk. As with all investments, an investment in the Fund is subject to investment risk. Investors in the Fund could lose money, including the possible loss of the entire principal amount of an investment, over short or long periods of time.

■

Market Risk. The trading prices of fixed income securities and other instruments fluctuate in response to a variety of factors, such as events that impact the entire market, market segments, or specific issuers. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

■

Shares of the Fund May Trade at Prices Other Than NAV. As with all exchange-traded funds ("ETFs"), Fund shares may be bought and sold in the secondary market at market prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and there may be times when the market price of the shares is more than the NAV (premium) or less than the NAV (discount). This risk is heightened in times of market volatility or periods of steep market declines.

■

Cash Redemption Risk. The Fund generally redeems shares for cash or otherwise includes cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments in order to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

■

Counterparty and Issuer Credit Risk. The financial condition of an issuer of a debt security or other instrument or a counterparty to a derivative or other contract may cause such issuer or counterparty to default, become unable to pay interest or principal due or otherwise fail to honor its obligations or cause such issuer or counterparty to be perceived (whether by market participants, rating agencies, pricing services or otherwise) as being in such situations. The value of an investment in the Fund may change quickly and without warning in response to issuer or counterparty defaults, changes in the credit ratings of the Fund’s portfolio investments and/or perceptions related thereto.

■

Derivatives Risk. The Fund invests in derivatives, including as a substitute to gain short exposure to U.S. Treasuries. Derivatives are financial instruments that derive their performance from an underlying reference asset, such as a commodity, index, interest rate or inflation rate. The return on a derivative instrument may not correlate with the return of its underlying reference asset. Derivatives are subject to a number of risks described elsewhere in the Fund’s Prospectus, such as counterparty and issuer credit risk, interest rate risk, market risk and issuer-specific risk. Derivatives can be volatile and may be less liquid than other securities. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money. In addition to the other risks associated with the use of derivatives described elsewhere in this Prospectus, there are risks associated with the Fund’s use of futures contracts. With respect to futures contracts and short exposure through futures contracts, these risks include but are not limited to: (1) the success of the adviser’s and sub-adviser’s ability to predict movements in the prices of individual currencies or securities, fluctuations in markets and movements in interest rates; (2) an imperfect or no correlation between the changes in market value of the currencies or securities and the prices of futures contracts; and (3) no guarantee that an active market will exist for the contracts at any particular time. In addition, while the Fund may short securities such as U.S. Treasuries, the Fund’s anticipated short exposure through derivative instruments may lead to less correlation with the Index.

■

Geopolitical Risk. Some countries and regions in which the Fund invests have experienced security concerns, war, threats of war, aggression and/or conflict, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations (including due to events outside of such countries or regions) that have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally, each of which may negatively impact the Fund’s investments.

■

Hedging Risk. The Index’s short positions in U.S. Treasuries, as well as the Fund’s holdings to obtain such exposure, are not intended to mitigate credit risk or mitigate changes in bond values associated with investor perceptions regarding, or premiums placed on, credit risk (i.e., credit risk premiums) or otherwise mitigate risks associated with other factors influencing the price of such bonds, which may have a greater impact than rising or falling interest rates. Investors should anticipate that due to the negative duration target, the Fund will be highly sensitive to interest rate changes. The higher (whether positive or negative) a bond fund’s duration, the greater

WisdomTree Trust Prospectus  3

its sensitivity to interest rates changes and fluctuations in value, whether positive or negative, will be more pronounced. For example, the Fund, in seeking to track the Index with a negative five-year duration target, could potentially decrease in value by five percent (or more) if interest rates fall one percent. Accordingly, the short positions will likely result in negative Fund performance if interest rates fall, including significant negative Fund performance in a falling interest rate environment. The Index’s short positions also may fail to provide the targeted duration in light of changes in the shape of the U.S. Treasury curve. The interest rate profile between the long and short exposures of the Index and Fund could also evolve significantly between monthly rebalancing. This could lead to temporary dislocations between the Fund’s intended and actual sensitivity to interest rates, which could impact performance. There may also be significant differences between the bond markets and U.S. Treasury markets (including futures markets for U.S. Treasuries) that could result in the Fund’s short positions performing ineffectively, exacerbating losses or causing greater tracking error. In addition, when interest rates fall, an unhedged investment in the same long portfolio of bonds will outperform the Fund.

■

Index and Data Risk. The Fund is not “actively” managed and will seek to track the price and yield performance, before fees and expenses, of the Index. The Index provider has the right to make adjustments to the Index or to cease making the Index available without regard to the particular interests of the Fund or its shareholders. If the computers or other facilities of the Index provider, Index calculation agent, data providers and/or relevant stock exchange malfunction for any reason, calculation and dissemination of Index values may be delayed and trading in Fund shares may be suspended for a period of time. Errors in Index data, Index calculations and/or the construction of the Index may occur from time to time and may not be identified and/or corrected by the Index provider, Index calculation agent or other applicable party for a period of time or at all, which may have an adverse impact on the Funds and their shareholders. The potential risk of continuing error may be particularly heightened in the case of the Index, which is generally not used as a benchmark by other funds or managers.

■

Interest Rate Risk. Interest rate risk with respect to the Fund is the risk that short exposure to fixed income securities will decline in value because of decreases in interest rates. In addition, longer average portfolio (including a longer negative duration) will cause the Fund to be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration.

■

Investment Style Risk. The Fund invests in the securities included in, or representative of, the Index regardless of their investment merit. The Fund does not attempt to outperform the Index or take defensive positions in declining markets. As a result, the Fund’s performance may be adversely affected by a general decline in the market segments relating to the Index.

■	Issuer-Specific Risk. Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.

■

Mortgage- and Asset-Backed Securities Risk. Movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain types of mortgage- and asset-backed securities. Mortgage- and asset- backed securities can also be subject to the risk of default on the underlying mortgages or other assets. Mortgage- and asset-backed securities are subject to fluctuations in yield due to prepayment rates that may be faster or slower than expected. Default or bankruptcy of a counterparty to a TBA Transaction would expose the Fund to possible loss.

■	Non-Correlation Risk. As with all index funds, the performance of the Fund and its Index may differ from each other for a variety of reasons.

■

Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers, and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.

■

Portfolio Turnover Risk. The Fund’s investment strategy may result in a high portfolio turnover rate. High portfolio turnover would result in correspondingly greater transaction expenses and may result in the distribution to shareholders of additional capital gains for tax purposes. These factors may negatively affect the Fund’s performance.

■

Short Sales Risk. The Fund will engage in “short sale” transactions. The Fund will lose value if the security or instrument that is the subject of a short sale increases in value. The Fund also may enter into short positions in equities and equity indexes as well as a short derivative position through swaps and futures contracts on equities

4  WisdomTree Trust Prospectus

and equity indexes. If the price of the security or derivative that is the subject of a short sale increases, then the Fund will incur a loss equal to the increase in price from the time that the short sale was entered into plus any premiums and interest paid to a third party in connection with the short sale. The risk of loss on a shorted position arises from the increase in value of the security sold short and is potentially unlimited unlike the risk of loss on a long position, which is limited to the amount paid for the investment plus transaction costs. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the investment. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund. Further, in times of unusual or adverse economic, market or political conditions, neither the Index nor the Fund may be able to fully or partially implement its short selling strategy.

■

U.S. Treasury Exposure Risk. The methodology used to select U.S. Treasuries for the Index (or U.S. Treasuries or U.S. Treasury futures, in the case of the Fund) for different maturities within the short exposure could produce performance that is dissimilar from other U.S. Treasuries of similar maturities. For example, unique supply and demand conditions could create a market whereby selected U.S. Treasuries or positions trade either more or less expensively than other U.S. Treasuries or positions of the same maturity, which could negatively impact the performance of the Fund.

■

Yield Curve Risk. The Index and Fund will have short exposure to U.S. Treasuries with different maturity dates and weightings and the Index and Fund are expected to be more heavily weighted to longer maturity U.S. Treasuries. The short exposure in the Index and the Fund, respectively, is expected to have greater sensitivity to interest rates than the long exposure of the Index and the Fund, respectively, in targeting the desired overall interest rate sensitivity, which has a duration of less than zero. Interest rates do not change uniformly for U.S. Treasuries of differing lengths of maturity in response to market and economic conditions. For example, interest rates for shorter maturity U.S. Treasuries may rise or fall more or less than interest rates for longer maturity U.S. Treasuries and rates may rise for U.S. Treasuries of certain maturities but fall for U.S. Treasuries of different maturities. Changes in interest rates among U.S. Treasuries with different maturities could impact returns produced both by the long exposures and short exposures of the Index and Fund in different ways, which could lead to unexpected performance, including Fund losses. This risk is heightened for the Index and the Fund, respectively, given the difference in maturity exposures between the long exposure and short exposure with the Index and Fund, respectively. The methodology of the Index and the investment approach of the Fund seek to address this risk, but are subject to the constraints of providing the desired overall interest rate profile and evolving market conditions, and there is no guarantee that any such risk will be reduced or the desired outcome will occur.

Fund Performance

Historical Fund performance, which varies over time, can provide an indication of the risks of investing in the Fund. The bar chart that follows shows the annual total returns of the Fund for each full calendar year since the Fund commenced operations. The table that follows the bar chart shows the Fund’s average annual total returns, both before and after taxes. This table also shows how the Fund’s performance compares to the Index and that of a relevant broad-based securities index. Index returns do not reflect deductions for fees, expenses or taxes. All returns assume reinvestment of dividends and distributions. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

The Fund’s year-to-date total return as of September 30, 2016 was (3.09)%.

Best and Worst Quarter Returns (for the periods reflected in the bar chart above)

	Return	Quarter/Year
Highest Return	2.13%	2Q/2015
Lowest Return	(3.09)%	4Q/2014

After-tax returns are calculated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown and are not relevant if you hold your shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period.

Management

Investment Adviser and Sub-Adviser

WisdomTree Asset Management, Inc. serves as investment adviser to the Fund. Mellon Capital Management Corporation (“Mellon Capital”) serves as sub-adviser to the Fund.

Portfolio Managers

The Fund is managed by Mellon Capital's Fixed Income Portfolio Management team. The individual members of the team jointly and primarily responsible for the day-to-day management of the Fund’s portfolio are described below.

Paul Benson, CFA, CAIA, Managing Director, Head of Fixed Income Portfolio Management, has been a portfolio manager of the Fund since October 2015.

Stephanie Shu, CFA, Director, Senior Portfolio Manager, Fixed Income, has been a member of the portfolio management team for the Fund since inception and a portfolio manager of the Fund since October 2015.

Buying and Selling Fund Shares

The Fund is an ETF. This means that shares of the Fund are listed on a national securities exchange, such as NASDAQ, and trade at market prices. Most investors will buy and sell shares of the Fund through brokers. Because Fund shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (premium) or less than NAV (discount).

The Fund issues and redeems shares at NAV only in large blocks of shares (“Creation Units”), which only certain institutions or large investors (typically market makers or other broker-dealers) may purchase or redeem. Currently, Creation Units generally consist of 100,000 shares, though this may change from time to time. Creation Units are not expected to consist of less than 50,000 shares. The Fund issues and redeems Creation Units in exchange for a portfolio of securities and/or U.S. cash.

Tax Information

The Fund intends to make distributions that may be taxed as ordinary income or capital gains.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), WisdomTree Asset Management, Inc. or its affiliates may pay Intermediaries for certain activities related to the Fund, including participation in activities that are designed to make Intermediaries more

6  WisdomTree Trust Prospectus

knowledgeable about exchange traded products, including the Fund, or for other activities, such as marketing, educational training or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the Intermediary and your salesperson to recommend the Fund over another investment. Any such arrangements do not result in increased Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.
