Research on MarketPlays
Two minutes to know any stock cold.

Free to start on the web, iPhone, and Android.

Research that starts from real holdings
AI research on every stock
A plain-language read on any name in the market: summary, bull case, bear case, key risks, and catalysts. It explains; it never picks for you.
Theme portfolios from real data
350+ themes turned into baskets of real companies, part drawn from what major ETFs hold and part from what real investors hold across connected brokerages.
Track before you commit
Browse themes, read the research, and watch how portfolios move without connecting anything. Bring a brokerage only when you want to invest.
How a theme becomes a portfolio
ETF holdings, unpacked
We look at what major ETFs actually hold and pull out the companies behind each theme, so the base stays broad and steady.
The crowd, aggregated
Positions from connected brokerages join in as an anonymous aggregate: what real investors hold, never any individual's portfolio.
Blended per theme
Each of the 350+ themes blends both sources, 40 percent crowd and 60 percent ETF by default, adjustable with one slider.
Research questions
Is the research free?
Yes. Browsing theme portfolios, reading AI research, and tracking performance are free. Free accounts also include 2 trades a month once you connect a brokerage.
What does the AI research cover?
For any stock: a plain-language summary of the business, the bull case, the bear case, key risks, and upcoming catalysts. It never picks stocks for you, and nothing in the app is personalized advice.
Where do the portfolio holdings come from?
Two sources of real companies: an ETF side drawn from what major ETFs hold, and a crowd side drawn from what investors here actually hold, synced from connected brokerages and aggregated anonymously. The default split is 40 percent crowd and 60 percent ETF, adjustable with one slider.
Do I need a brokerage account?
Not to browse. Research, themes, and portfolio tracking work without one. To invest, connect one of 9 brokerages, including Robinhood, Webull, and E*TRADE, and place the whole basket in one order.
