Webull’s Meritz partnership puts AI research inside a local brokerage account

Webull’s 1 October 2026 announcement identifies a route for distributing its Vega AI, investor community and US-equity access through another broker: Meritz Securities’ MOUM platform in South Korea. The arrangement builds on a partnership first announced in November 2025.[1]

The platform was already operating. Yonhap reported Meritz’s formal Korean launch on 1 September, a month before Webull’s international disclosure. Its account of the rollout distinguishes browsing without registration, community participation through a social login, and full functions after linking a Meritz Super365 investment account.[2]

Vega’s disclosed role is to help analyse company filings, earnings reports and news. Webull also contributes access to its global investor discussions. Commercially, the partnership distributes these components inside Meritz’s customer experience, giving the technology supplier a route to investors who use a local brokerage account. The announcement does not disclose licensing fees or a revenue split.[1]

Research, account access and orders

MOUM’s current product page combines portfolio-linked information and AI chat with EASY and PRO order interfaces. These are research and customer-order functions in the published description; it does not announce discretionary trading authority for Vega. Linking an account makes information relevant to holdings, but that is a different permission from letting an AI decide and submit trades.[3]

The account’s opening date changes the US-stock bill

For a hypothetical $10,000 US-share purchase, the newer-account rates imply $7 for a standard trade or $25 for fractional trading, before other charges. The domestic-stock and US-dollar exchange-fee waivers for these accounts run through the stated 2026 campaign, rather than extending the older US-stock waiver to everyone.[4]

For customers first opening Super365 from May 2025, commission-free turnover is generally capped at KRW20 billion monthly; the qualifying turnover differs by account cohort. Exceeding it triggers base commissions from local-market D+2 through month-end, with the waiver restored next month.[4]

Community rewards connect back to brokerage

MOUM also rewards participation with points. The first post receives a random 500–1,000,000 points; subsequent posts and comments have separate limits. One point converts to KRW1, but conversion requires a Super365 account, at least 100 available points and increments of 100. Credits arrive the next business day; conversion caps are KRW500,000 daily and KRW5 million annually, and unused points expire after a year.[3]

That account requirement links social engagement to brokerage participation. The reward’s maximum advertised amount is neither a fixed payment nor investment performance; random allocation and conversion conditions determine what a participant actually receives.[3]
