What Minkabu does

Minkabu (株式会社みんかぶ) is a Tokyo-based financial information and social media platform founded in 2012 that targets Japanese retail investors. It aggregates stock prices, charts, news, shareholder benefits, IPO data, and corporate IR content, and layers on community features such as the みんなの株価予想 (user stock prediction) feed, where individual investors post buy/sell calls that are aggregated into collective sentiment signals. The platform combines a content/media surface (mag.minkabu.jp), a portfolio management tool (みんかぶポートフォリオ), a multi-account asset aggregation service (Asepla / アセットプランナー), a stock screening tool (銘柄スクリーニング), and a corporate IR service (IRwith), supported by data partnerships with Tokyo Stock Exchange, Nagoya Stock Exchange, Fisco, Kabutan, Morningstar Japan, JPX, CME Group, S&P Global, and Tokyo Commodity Exchange.

The product surface has expanded well beyond domestic equities into adjacent asset classes via dedicated subdomains covering US stocks, FX, crypto, futures, investment trusts, and insurance, plus comparison hubs for online brokerages, credit cards, and loans. Underlying technology is described as a proprietary financial information aggregation platform combining exchange feeds and third-party data with user-generated and "AI-assisted" prediction analytics, delivered via web and mobile on a self-serve basis.

Minkabu monetizes through a freemium model: a free tier with limited features, a 30-day free trial, and a premium subscription (みんかぶプレミアム) at ¥2,980/month (tax included) offering ad-free browsing and exclusive tools, alongside display advertising and affiliate/referral commissions routed to partner financial products. Go-to-market is product-led with no explicit sales team, relying on organic search, content marketing, email/newsletter, and built-in social/community features for acquisition and engagement. The company is privately held with 11-50 employees.

Direct peers

• Kabutan (株探): Japanese stock analysis and screening platform providing detailed financial data, news, and analyst forecasts. Directly competes with Minkabu on equities coverage and is also a data partner, illustrating the overlap between competitor and supplier.
• TradingView: Global charting and social-trading platform with multi-asset coverage, community scripts, and idea sharing — competes with Minkabu's screening, charting, and community features across retail investor users.
• Yahoo! Finance Japan: Japan's dominant financial information portal combining market data, news, portfolio tools, and community content for retail investors — the primary head-to-head competitor to Minkabu in the Japanese retail-investor information market.
• The Motley Fool: Retail-investor-focused investment advisory and community platform offering premium stock recommendations and educational content — comparable premium-subscription-plus-community model targeting individual investors.
• StockTwits: Social networking platform dedicated to traders and investors, aggregating real-time sentiment and discussion around individual stocks. Direct functional analog to Minkabu's social/community layer for retail investors.
• Zacks Investment Research: US-based investment research platform providing stock rankings, analyst estimates, and educational content for retail investors — comparable business model focused on screening, ranking, and consensus-style forecasting.
• Seeking Alpha: Crowd-sourced investment analysis platform combining contributor research, stock opinions, and quantitative ratings — the closest Western analog to Minkabu's user-generated prediction and discussion model for retail investors.
• Investing.com (Japan): Global multi-asset financial information and data platform with a dedicated Japan portal covering stocks, FX, futures, and commodities — competes with Minkabu's cross-asset coverage and real-time data features.

Broad incumbents

• Bloomberg: Global financial data, news, and analytics provider with broad multi-asset coverage. Overlaps with Minkabu on market data and news but serves a more professional/institutional audience and offers much deeper product breadth.
• Monex Securities: Japanese online broker with proprietary research, market data, and community/information features for its trading customers — both a potential affiliate partner and competitor to Minkabu's research and stock-coverage content.
