Yes, it is possible to invest $1 in stocks. There are some platforms that allow investors to buy fractional shares of stocks, which means you can buy a portion of a stock instead of a whole share. This allows you to invest small amounts of money and still have exposure to the stock market.
However, keep in mind that some brokerages may have minimum investment requirements or fees for purchasing fractional shares. It's important to research and compare different brokerage platforms to find the one that best fits your investment needs and budget.
