FIS vs IBKR Comparison

Fidelity National Information Services provides core processing and ancillary services to banks, but its business has expanded over time. By acquiring SunGard in 2015, the company now provides record-keeping and other services to investment firms. With the acquisition of Worldpay in 2019, FIS was providing payment processing services for merchants and holding leading positions in the United States and United Kingdom. But the company sold off a majority interest in Worldpay and now has only a minority stake.
