Webull and Sentinel AI have launched a pilot program that lets public companies engage retail investors where they trade. Announced on October 28, 2026, it pairs Webull's Corporate Connect service with Sentinel's retail sentiment tracking. Companies get a verified page in the Webull app, which has more than 29 million registered users worldwide. Sentinel shows them the bullish and bearish narratives forming around their stock on social platforms and online news, and their investor relations teams use that to shape approved updates. Followers are notified each time a company posts. The move follows a rise in retail trading, which accounted for as much as 36% of US stock market trading in 2025, according to JPMorgan, against a ten-year average of roughly 12%. The pilot starts with a select group of public companies, with expansion planned after the initial results.

Webull and Sentinel AI launch pilot program bringing public companies to retail investors at the point of trade. Program pairs Webull Corporate Connect with Sentinel[[ʼ]]s retail narrative intelligence, so public companies can answer what retail investors are asking on the page where they trade. October 28, 2026 13:11 ET | Source: Sentinel AI ST. PETERSBURG, Fla. and MIAMI, Oct. 28, 2026 (GLOBE NEWSWIRE) - via IBN - Webull and Sentinel AI today announced a joint pilot program that gives public companies a new way to engage retail investors. The pilot program gives a listed company a direct channel to retail investors through their page on Webull[[ʼ]]s Corporate Connect Service, where retail investors can interact with it at the point of trade, Sentinel AI[[ʼ]]s real time visibility into the bullish and bearish narratives forming around its stock across social platforms and online news, and a response shaped with their IR team. Retail investors accounted for as much as 36% of US stock market trading in 2025, according to JPMorgan, against a ten-year average of roughly 12%. The conversation that shapes how those investors see a company happens every day across social platforms and online news, and most companies still reach retail investors with generic updates through channels they do not use when they decide to buy. Webull Corporate Connect gives public companies a verified page inside the Webull app where they can publish news and updates, answer investor questions, and build a following among Webull[[ʼ]]s more than 29 million registered users worldwide. Investors who follow a company receive a notification each time it posts. Michael Christoph, Head of Capital Markets, Webull: "Corporate Connect was built to give public companies a direct line to retail investors. Pairing it with Sentinel[[ʼ]]s narrative data means the companies on our platform will be posting content that answers what our users are actually asking. That is good for the companies, and it is good for the investors who follow them on Webull.[[ˮ]] The program is built to connect public companies and retail investors more meaningfully. Webull puts company updates in front of retail investors on the company[[ʼ]]s Corporate Connect page, Sentinel gives each company a real time read on retail sentiment and the narratives behind it, and the company[[ʼ]]s IR team turns that read into updates the company approves. Investors get a company that hears them and answers, in the place where they already follow and trade the stock. Krishan Arora, Founder and CEO, Sentinel AI: "Retail investors act on stories before they act on fundamentals, and those stories form on social media every day. Sentinel detects the narratives moving a stock; this program closes the loop by putting the company[[ʼ]]s response in front of investors at the point of trade. Webull brings the audience and Sentinel brings the intelligence, allowing direct communication, access and trading within a trusted environment.[[ˮ]] Mark Roberts, Managing Partner, The Blueshirt Group: "Retail investors are a growing part of our clients[[ʼ]] shareholder base, and most companies still reach them with the same tools they used a decade ago. The Sentinel offering provides real-time insight into what retail investors are saying, which in turn can better inform the effectiveness of public companies[[ʼ]] messaging.[[ˮ]] The pilot begins with a select group of public companies, with expansion planned after the initial results.
