About Webull US
Webull's US operations were incorporated in 2017 in New York and quickly established itself as the go-to platform for active retail traders who wanted professional tools without the cost. Unlike Robinhood's gamified design, Webull leaned into data density — offering Level 2 quotes, advanced screeners, and detailed options analytics for free at a time when competitors charged monthly subscriptions for equivalent tools.
By 2026, Webull had exceeded 27 million global users and launched 24/5 trading on select US equities, a first for a mainstream retail broker. Its paper trading environment and comprehensive free data suite make it an ideal platform for new algorithmic traders who want to develop and test strategies before deploying real capital. The AInvest integration combines Webull's real-time data infrastructure with AI-powered signal generation for a complete active trading solution.
