This is a list of the five most risky businesses in the world. These companies are at high risk of losing money and constantly trying to keep up with the market. Did you know that Uber and tesla are businesses that are considered high-risk? Uber has been in the e-hailing business for almost ten years and has had its fair share of ups and downs. Uber has been sued by nearly every country it operates in, making it one of the riskiest companies to invest in. Tesla is also a precarious business because they have only been around for 15 years and have not made a profit yet. They have more than $10 billion in debt, which makes them very dependent on their stock price to stay afloat.
