All investments involve the risk of loss and the past performance of a security or a financial product does not guarantee future results or returns. You should consult your legal, tax, or financial advisors before making any financial decisions. This material is not intended as a recommendation, offer, or solicitation to purchase or sell securities, open a brokerage account, or engage in any investment strategy.

Stocks, ETFs, Options, Bonds.
Self-directed brokerage accounts and brokerage services for US-listed, registered securities, options, and Bonds, except for treasury securities offered through Jiko Securities, Inc., are offered to self-directed customers by Open to the Public Investing, Inc. (“Public Investing”), a registered broker-dealer and member of FINRA & SIPC. Additional information about your broker can be found by clicking here. Public Investing is a wholly-owned subsidiary of Public Holdings, Inc. (“Public Holdings”). This is not an offer, solicitation of an offer, or advice to buy or sell securities or open a brokerage account in any jurisdiction where Public Investing is not registered. Securities products offered by Public Investing are not FDIC insured. Apex Clearing Corporation, our clearing firm, has additional insurance coverage in excess of the regular SIPC limits. Additional information can be found here.

Options.
Certain requirements must be met in order to trade options. Options can be risky and are not suitable for all investors. Options transactions are often complex, and investors can rapidly lose the entire amount of their investment or more in a short period of time. Investors should consider their investment objectives and risks carefully before investing in options. Refer to the Characteristics and Risks of Standardized Options before considering any options transaction. Supporting documentation for any claims, if applicable, will be furnished upon request. Tax considerations with options transactions are unique and investors considering options should consult their tax advisor as to how taxes affect the outcome of each options strategy.

Options Order Flow Rebates.
If you are enrolled in our Options Order Flow Rebate Program, Public Investing will share a percentage of our estimated order flow revenue for each completed options trade as a rebate to help reduce your trading costs. Rebate rates vary monthly from $0.06-$0.18 and depend on your current and prior month’s options trading volume. This rebate will be deducted from your cost to place the trade and will be reflected on your trade confirmation. To learn more, see our Options Rebate Program Terms & Conditions, Order Rebate FAQ and Fee Schedule.

Bonds.
“Bonds” shall refer to corporate debt securities and U.S. government securities offered on the Public platform through a self-directed brokerage account held at Public Investing and custodied at Apex Clearing. For purposes of this section, Bonds exclude treasury securities held in treasury accounts with Jiko Securities, Inc. as explained under the “ Treasury Accounts” section.

Investments in Bonds are subject to various risks including risks related to interest rates, credit quality, market valuations, liquidity, prepayments, early redemption, corporate events, tax ramifications and other factors. The value of Bonds fluctuate and any investments sold prior to maturity may result in gain or loss of principal. In general, when interest rates go up, Bond prices typically drop, and vice versa. Bonds with higher yields or offered by issuers with lower credit ratings generally carry a higher degree of risk. All fixed income securities are subject to price change and availability, and yield is subject to change. Bond ratings, if provided, are third party opinions on the overall bond's credit worthiness at the time the rating is assigned. Ratings are not recommendations to purchase, hold, or sell securities, and they do not address the market value of securities or their suitability for investment purposes.

A Bond Account is a self-directed brokerage account with Public Investing. Deposits into this account are used to purchase 10 investment-grade and high-yield bonds. The Bond Account’s yield is the average, annualized yield to worst (YTW) across all ten bonds in the Bond Account, before fees. A bond’s yield is a function of its market price, which can fluctuate; therefore a bond’s YTW is not “locked in” until the bond is purchased, and your yield at time of purchase may be different from the yield shown here. The “locked in” YTW is not guaranteed; you may receive less than the YTW of the bonds in the Bond Account if you sell any of the bonds before maturity or if the issuer defaults on the bond. Public Investing charges a markup on each bond trade. See our Fee Schedule.

Bond Accounts are not recommendations of individual bonds or default allocations. The bonds in the Bond Account have not been selected based on your needs or risk profile. You should evaluate each bond before investing in a Bond Account. The bonds in your Bond Account will not be rebalanced and allocations will not be updated, except for Corporate Actions.

Fractional Bonds also carry additional risks including that they are only available on Public and cannot be transferred to other brokerages. Read more about the risks associated with fixed income and fractional bonds. See Bond Account Disclosures to learn more.

High-Yield Cash Account.
A High-Yield Cash Account is a secondary brokerage account with Public Investing. Funds in your High-Yield Cash Account are automatically deposited into partner banks (“Partner Banks”), where that cash earns interest and is eligible for FDIC insurance. See here for a list of current Partner Banks. Your Annual Percentage Yield is variable and may change at the discretion of the Partner Banks or Public Investing. Apex Clearing and Public Investing receive administrative fees for operating this program, which reduce the amount of interest paid on swept cash. Neither Public Investing nor any of its affiliates is a bank. Learn more.

Cryptocurrency.
Cryptocurrency trading, execution and custody services are provided by Zero Hash LLC (“Zero Hash”). Zero Hash is licensed to engage in a virtual currency business by the New York State Department of Financial Services, and is a licensed money transmitter in all other US states and certain US territories. Zero Hash is not a registered broker-dealer or a member of FINRA. Cryptocurrencies are not stocks and your cryptocurrency investments are not FDIC insured or SIPC protected.

Cryptocurrency investing is highly speculative, involves a high degree of risk, and has the potential for loss of the entire amount of an investment. Cryptocurrencies offered by Zero Hash are not securities and are not FDIC insured or protected by SIPC. Your cryptocurrency assets are held by Zero Hash, not Public. Your Zero Hash Crypto account is separate from your brokerage account with Public Investing, which holds US-listed stocks and ETFs. Please review the Risk Disclosures before trading.

Treasury Accounts.
Investing services in treasury accounts offering 6 month US Treasury Bills on the Public platform are through Jiko Securities, Inc. (“JSI”), a registered broker-dealer and member of FINRA & SIPC. See JSI’s FINRA BrokerCheck and Form CRS for further information. JSI uses funds from your Treasury Account to purchase T-bills in increments of $100 “par value” (the T-bill’s value at maturity). T-bills are purchased at a discount to the par value and the T-bill’s yield represents the difference in price between the “par value” and the “discount price.” Aggregate funds in your Treasury Account in excess of the T-bill purchases will remain in your Treasury Account as cash. The value of T-bills fluctuate and investors may receive more or less than their original investments if sold prior to maturity. T-bills are subject to price change and availability - yield is subject to change. Past performance is not indicative of future performance. Investments in T-bills involve a variety of risks, including credit risk, interest rate risk, and liquidity risk. As a general rule, the price of a T-bills moves inversely to changes in interest rates. Although T-bills are considered safer than many other financial instruments, you could lose all or a part of your investment. See Jiko U.S. Treasuries Risk Disclosures for further details.

Investments in T-bills: Not FDIC Insured; No Bank Guarantee; May Lose Value.
