UNITED STATES GASOLINE FUND, LP 

Supplement dated October 1, 2020

to

Prospectus dated April 24, 2020

This supplement contains information that amends, supplements or modifies certain information contained in the prospectus of United States Gasoline Fund, LP (“UGA”) dated April 24, 2020 (the “Prospectus”).

You should carefully read the Prospectus and this supplement before investing. This supplement should be read in conjunction with the Prospectus. You should also carefully consider the “Risk Factors” beginning on page 4 of the Prospectus before you decide to invest.

The following changes are hereby made to the Prospectus and each corresponding section:

Investors who buy or sell shares during the day from their broker may do so at a premium or discount relative to the market value of the underlying gasoline futures contracts in which UGA invests due to supply and demand forces at work in the secondary trading market for shares that are closely related to, but not identical to, the same forces influencing the prices of gasoline and the gasoline futures contracts that serve as UGA’s investment benchmark. INVESTING IN UGA INVOLVES RISKS SIMILAR TO THOSE INVOLVED WITH AN INVESTMENT DIRECTLY IN THE GASOLINE MARKET, BUT IT IS NOT A PROXY FOR TRADING DIRECTLY IN THE GASOLINE MARKETS. Investing in UGA also involves the correlation risk described below and other significant risks. You should consider carefully the risks described below before making an investment decision. See “Risk Factors Involved with an Investment in UGA” beginning on page 4.

UGA seeks to achieve its investment objective by investing so that the average daily percentage change in UGA’s NAV for any period of 30 successive valuation days will be within plus/minus ten percent (10%) of the average daily percentage change in the price of the Benchmark Futures Contract over the same period.

Investors may choose to use UGA as a means of investing indirectly in unleaded gasoline.

As of the date of this prospectus, significant market volatility has occurred in the oil markets and the oil futures markets. Such volatility is attributable to the COVID-19 pandemic, disputes among oil-producing companies, a corresponding collapse in demand for oil and a lack of on-land storage for oil. Although the volatility has abated in recent months, future volatility cannot be predicted. Volatility in the gasoline market was also elevated, but it did not reach the same extreme levels as the volatility in the oil futures market did. However, the COVID-19 pandemic could cause increased volatility in the future, the impact of which could limit UGA’s ability to have a substantial portion of its assets invested in the Benchmark Futures Contract. In such a circumstance, UGA could, if it determined it appropriate to do so in light of market conditions and regulatory requirements, invest in other Futures Contract and/or Other Gasoline Related Investments.

UGA is not leveraged.

UGA has not leveraged, and does not intend to leverage, its assets through borrowings or otherwise, and makes its investments accordingly. Consistent with the foregoing, UGA’s announced investment intentions, and any changes thereto, will take into account the need for UGA to make permitted investments that also allow it to maintain adequate liquidity to meet its margin and collateral requirements and to avoid, to the extent reasonably possible, UGA becoming leveraged. If market conditions require it, these risk reduction procedures may occur on short notice if they occur other than during a roll or rebalance period.

UGA may temporarily limit the offering of Creation Baskets.

UGA may determine to limit the issuance of its shares through the offering of Creation Baskets to its Authorized Participants in order to allow it to reinvest the proceeds from sales of its Creation Baskets in currently permitted assets in a manner that meets its investment objective.

UGA will announce to the market through the filing of a Current Report on Form 8-K if it intends to limit the offering of Creation Baskets at any time. In such case, orders for Creation Baskets will be considered for acceptance in the order they are received by UGA and UGA would continue to accept requests for redemption of its shares from Authorized Participants through Redemption Baskets during the period of the limited offering of Creation Baskets.

UGA’s investment objective is for the daily percentage changes in the NAV per share to reflect the daily percentage changes of the spot price of gasoline (also known as reformulated gasoline blendstock for oxygen blending, or “RBOB”, for delivery to the New York harbor), as measured by the daily changes in the price of the futures contract for gasoline traded on the New York Mercantile Exchange (the “NYMEX”), that is the near month contract to expire, except when the near month contract is within two weeks of expiration, in which case the futures contract will be the next month contract to expire (the “Benchmark Futures Contract”), plus interest earned on UGA’s collateral holdings, less UGA’s expenses. UGA seeks to achieve its investment objective by investing so that the average daily percentage change in UGA’s NAV for any period of 30 successive valuation days will be within plus/minus ten percent (10%) of the average daily percentage change in the price of the Benchmark Futures Contract over the same period. UGA’s investment strategy is designed to provide investors with a cost-effective way to invest indirectly in unleaded gasoline and to hedge against movements in the spot price of unleaded gasoline.

Variables such as drought, floods, weather, pandemics, embargoes, tariffs and other political events may have a larger impact on gasoline prices and gasoline linked instruments, including Futures Contracts and Other Gasoline-Related Investments, than on traditional securities.

As of the date of this prospectus, significant market volatility has occurred in the oil markets and the oil futures markets. Such volatility is attributable to the COVID-19 pandemic, disputes among oil-producing companies, a corresponding collapse in demand for oil and a lack of on-land storage for oil. Although the volatility has abated in recent months, future volatility cannot be predicted. Volatility in the gasoline market was also elevated, but it did not reach the same extreme levels as the volatility in the oil futures market did. However, the COVID-19 pandemic could cause increased volatility in the future, the impact of which could limit UGA’s ability to have a substantial portion of its assets invested in the Benchmark Futures Contract. In such a circumstance, UGA could, if it determined it appropriate to do so in light of market conditions and regulatory requirements, invest in other Futures Contract and/or Other Gasoline Related Investments.

For example, a shortage of UGA shares in the market and other factors could cause UGA’s shares to trade at a premium. Investors should be aware that such premiums can be transitory. To the extent an investor purchases shares that include a premium (e.g., because of a shortage of shares in the market due to the inability of Authorized Participants to purchase additional shares from UGA that could be resold into the market) and the cause of the premium no longer exists causing the premium to disappear (e.g., because more shares are available for purchase from UGA by Authorized Participants that could be resold into the market) such investor’s return on its investment would be adversely impacted due to the loss of the premium.

An investment in UGA is not a proxy for investing in the gasoline markets, and the daily percentage changes in the price of the Benchmark Futures Contract, or the NAV of UGA, may not correlate with daily percentage changes in the spot price of gasoline.

An investment in UGA is not a proxy for investing in the gasoline markets. To the extent that investors use UGA as a means of indirectly investing in gasoline, there is the risk that the daily changes in the price of UGA’s shares on the NYSE Arca, on a percentage basis, will not closely track the daily changes in the spot price of gasoline on a percentage basis. This could happen if the price of shares traded on the NYSE Arca does not correlate closely with the value of UGA’s NAV; the changes in UGA’s NAV do not correlate closely with the changes in the price of the Benchmark Futures Contract; or the changes in the price of the Benchmark Futures Contract do not closely correlate with the changes in the cash or spot price of gasoline. This is a risk because if these correlations do not exist, then investors may not be able to use UGA as a cost-effective way to indirectly invest in gasoline or as a hedge against the risk of loss in gasoline-related transactions. The degree of correlation among UGA’s share price, the price of the Benchmark Futures Contract and the spot price of gasoline depends upon circumstances such as variations in the speculative gasoline market, supply of and demand for Futures Contracts (including the Benchmark Futures Contract) and Other Gasoline-Related Investments, and technical influences on trading gasoline futures contracts. Investors who are not experienced in investing in gasoline futures contracts or the factors that influence that market or speculative trading in the gasoline markets and may not have the background or ready access to the types of information that investors familiar with these markets may have and, as a result, may be at greater risk of incurring losses from trading in UGA shares than such other investors with such experience and resources.

Natural forces in the gasoline futures market known as “backwardation” and “contango” may increase UGA’s tracking error and/or negatively impact total return.

The design of UGA’s Benchmark Futures Contract is such that every month it begins by using the near month contract to expire until the near month contract is within two weeks of expiration, when, over a one day period, it transitions to the next month contract to expire as its benchmark contract and keeps that contract as its benchmark until it becomes the near month contract and close to expiration. In the event of a gasoline futures market where near month contracts trade at a higher price than next month to expire contracts, a situation described as “backwardation” in the futures market, then absent the impact of the overall movement in gasoline prices the value of the benchmark contract would tend to rise as it approaches expiration. Conversely, in the event of a gasoline futures market where near month contracts trade at a lower price than next month contracts, a situation described as “contango” in the futures market, then absent the impact of the overall movement in gasoline prices the value of the benchmark contract would tend to decline as it approaches expiration. When compared to total return of other price indices, such as the spot price of gasoline, the impact of backwardation and contango may cause the total return of UGA’s per share NAV to vary significantly. Moreover, absent the impact of rising or falling gasoline prices, a prolonged period of contango could have a significant negative impact on UGA’s per share NAV and total return and investors could lose part or all of their investment. See “Additional Information About UGA, its Investment Objective and Investments” for a discussion of the potential effects of contango and backwardation.

While contango and backwardation are consistently present in trading in the futures markets, such conditions can be exacerbated by market forces. For example, extraordinary market conditions in the crude oil markets, including “super contango” (a higher level of contango arising from the overabundance of oil being produced and the limited availability of storage for such excess supply), occurred, and may continue to occur for an unknown duration, in the crude oil futures markets due to over-supply of crude oil in the face of weak demand during the COVID-19 pandemic when disputes among oil-producing countries regarding limitations on the production of oil also were occurring. Volatility in the gasoline market was also elevated, but it did not reach the same extreme levels as the volatility in the oil futures market did. However, the COVID-19 pandemic could cause increased volatility in the future, the impact of which could limit UGA’s ability to have a substantial portion of its assets invested in the Benchmark Futures Contract. In such a circumstance, UGA could, if it determined it appropriate to do so in light of market conditions and regulatory requirements, invest in other Futures Contract and/or Gasoline Related Investments.

See “Additional Information About UGA, its Investment Objective and Investments” for a discussion of the potential effects of contango and backwardation.

Accountability levels, position limits, and daily price fluctuation limits set by the exchanges have the potential to cause tracking error, by limiting UGA’s investments, including its ability to fully invest in the Benchmark Futures Contract, which could cause the price of shares to substantially vary from the price of the Benchmark Futures Contract.

Risk mitigation measures imposed by UGA’s FCMs have the potential to cause tracking error by limiting UGA’s investments, including its ability to fully invest in the Benchmark Futures Contract and other Futures Contracts, which could cause the price of UGA’s shares to substantially vary from the price of the Benchmark Futures Contract.

UGA’s FCMs have discretion to impose limits on the positions that UGA may hold in the Benchmark Futures Contracts as well as certain other months. To date, UGA’s FCMs have not imposed any such limits. However, were UGA’s FCMs to impose limits, UGA’s ability to have a substantial portion of its assets invested in the Benchmark Futures Contract and other Futures Contracts could be severely limited, which could lead UGA to invest in other Futures Contracts or, potentially, Other Gasoline Related Investments. UGA could also have to more frequently rebalance and adjust the types of holdings in its portfolio than is currently the case. This could inhibit UGA from pursuing its investment objective in the same manner that it has historically and currently.

In addition, when offering Creation Baskets for purchase, limitations imposed by exchanges and/or any of UGA’s FCMs could limit UGA’s ability to invest the proceeds of the purchases of Creation Baskets in Benchmark Futures Contracts and other Futures Contracts. If this were the case, UGA may invest in other permitted investments, including Other Gasoline Related Investments, and may hold larger amounts of Treasuries, cash and cash equivalents, which could impair UGA’s ability to meet its investment objective.

UGA is not actively managed and its investment objective is to track the Benchmark Futures Contract so that the average daily percentage change in UGA’s NAV for any period of 30 successive valuation days will be within plus/minus ten percent (10%) of the average daily percentage change in the price of the Benchmark Futures Contract over the same period.

UGA is not actively managed by conventional methods. Accordingly, if UGA’s investments in Gasoline Interests are declining in value, in the ordinary course, UGA will not close out such positions except in connection with paying the proceeds to an Authorized Participant upon the redemption of a basket or closing out its positions in Futures Contracts and other permitted investments (i) in connection with the monthly change in the Benchmark Futures Contract or when UGA otherwise determines it would be appropriate to do so, e.g., due to regulatory requirements or risk mitigation measures, or to avoid UGA becoming leveraged, and it reinvests the proceeds in new Futures Contracts or Other Gasoline-Related Investments to the extent possible. USCF will seek to cause the NAV of UGA’s shares to track the Benchmark Futures Contract during periods in which its price is flat or declining as well as when the price is rising.

UGA’s ability to invest in the Benchmark Futures Contract could be limited as a result of any or all of the following: evolving market conditions, a change in regulator accountability levels and position limits imposed on UGA with respect to its investment in Futures Contracts, additional or different risk mitigation measures taken by market participants, generally, including UGA, with respect to UGA acquiring additional Futures Contracts, or UGA selling additional shares.

UGA may not meet the listing standards of NYSE Arca, which would adversely impact an investor’s ability to sell shares.

UGA’s shares are listed for trading on the NYSE Arca under the market symbol “UGA.” NYSE Arca may suspend UGA’s shares from trading on the exchange with or without prior notice to UGA, upon failure of UGA to comply with the NYSE’s listing requirements, or when in its sole discretion, the NYSE Arca determines that such suspension of dealings is in the public interest or otherwise warranted. There can be no assurance that the requirements necessary to maintain the listing of UGA’s shares will continue to be met or will remain unchanged. If UGA were unable to meet the NYSE’s listing standards and were to become delisted, an investor’s ability to sell its shares would be adversely impacted.

UGA could become leveraged if it had insufficient assets to completely meet its margin or collateral requirements relating to its investments.

Although UGA does not and will not borrow money or use debt to satisfy its margin or collateral obligations in respect of its investments, it could become leveraged if UGA were to hold insufficient assets that would allow it to meet not only the current, but also future, margin or collateral obligations required for such investments. Such a circumstance could occur if UGA were to hold assets that have a value of less than zero.

USCF endeavors to have the value of UGA’s Treasuries, cash and cash equivalents, whether held by UGA or posted as margin or other collateral, at all times approximate the aggregate market value of its obligations under its Futures Contracts and Other Gasoline-Related Investments. Although permitted to do so under its Limited Partnership Agreement, UGA has not and does not intend to leverage its assets by making investments beyond its potential ability to meet the potential margin and collateral obligations relating to such investments. Consistent with this, UGA’s investment decisions will take into account the need for UGA to make permitted investments that also allow it to maintain adequate liquidity to meet its margin and collateral requirements and to avoid, to the extent reasonably possible, UGA becoming leveraged, including by its holding of assets that have a high probability of having a value of less than zero.

USCF serves as the general partner or sponsor to each of UGA and the Related Public Funds. USCF may have a conflict to the extent that its trading decisions for UGA may be influenced by the effect they would have on the other funds it manages. By way of example, if, as a result of reaching position limits imposed by the NYMEX, UGA purchased gasoline futures contracts, this decision could impact UGA’s ability to purchase additional gasoline futures contracts if the number of contracts held by funds managed by USCF reached the maximum allowed by the NYMEX. Similar situations could adversely affect the ability of any fund to track its Benchmark Futures Contract.

In particular, unforeseen circumstances, including, but not limited to, (i) market conditions, regulatory requirements, risk mitigation measures taken by UGA or third parties or otherwise that would lead UGA to determine that it could no longer foreseeably meet its business objective or that UGA’s aggregate net assets in relation to its operating expenses or its margin or collateral requirements make the continued operation of UGA unreasonable or imprudent, or (ii) adjudication of incompetence, bankruptcy, dissolution, withdrawal or removal of USCF as the general partner of UGA could cause UGA to terminate unless a majority interest of the limited partners within 90 days of the event elects to continue the partnership and appoints a successor general partner, or the affirmative vote of a majority in interest of the limited partners subject to certain conditions.

While USCF makes every effort to predict and maintain an adequate amount of shares outstanding, if a substantial number of requests for Creation Baskets are received by UGA during a relatively short period of time that substantially differs from past creation volumes, due to market volatility or otherwise, it could result in circumstances where, because of high demand for its shares, UGA may not have sufficient shares available for sale to satisfy demand. Authorized Participants may, therefore, be unable to purchase additional Creation Baskets.

UGA may determine that to allow it to reinvest the proceeds from sales of its Creation Baskets in currently permitted assets in a manner that meets its investment objective it may limit its offers of Creation Baskets.

UGA may determine that UGA will limit the issuance of its shares through the offering of Creation Baskets to its Authorized Participants. As a result of certain circumstances described herein, including (1) the need to comply with regulatory requirements (including, but not limited to, exchange accountability levels and position limits); (2) market conditions (including but not limited to those allowing UGA to obtain greater liquidity or to execute transactions with more favorable pricing); and (3) risk mitigation measures taken by UGA’s current and other FCMs that limit UGA and other market participants from investing in particular gasoline futures contracts, UGA’s management can determine that it will limit the issuance of shares and the offerings of Creation Baskets because it is unable to invest the proceeds from such offerings in investments that would permit it to reasonably meet its investment objective.

If such a determination is made, the same consequences associated with a suspension of the offering of Creation Baskets, as described in the foregoing risk factor, An unanticipated number of creation requests during a short period of time could result in a shortage of shares, could also occur as a result of UGA determining to limit the offering of creation baskets.

UGA seeks to achieve its investment objective by investing so that that the average daily percentage change in UGA’s NAV for any period of 30 successive valuation days will be within plus/minus ten percent (10%) of the average daily percentage change in the price of the Benchmark Futures Contract over the same period.

Although permitted to do so under its Limited Partnership Agreement, UGA has not and does not intend to leverage its assets and makes its investments accordingly. Consistent with this, UGA’s investment decisions will take into account the need for UGA to make permitted investments that also allow it to maintain adequate liquidity to meet its margin and collateral requirements and to avoid, to the extent reasonably possible, UGA becoming leveraged, including by its holding of assets that have a high probability of causing the net asset value of the fund to be less than zero.
