Jane Street, a leading market maker responsible for over 10% of trading volume in the U.S. stock market, is under scrutiny as market conditions worsen. Alongside Citadel, Jane Street is a prominent automated market maker. In the current bearish market, market makers like Jane Street are often blamed for liquidity issues. To survive, some projects are shortening adjustment cycles, adjusting strike prices, or adopting subscription models. Regulatory bodies like the SEC or CFTC may impose stricter rules, requiring more transparency and higher penalties for violations. This could deter practices like the alleged 10 a.m. sell-offs, as the cost of non-compliance would be prohibitive.
