Thematic investing with real holdings
You call the theme.
We build the basket.
Pick from 350+ themes like AI, semiconductors, or clean energy. MarketPlays turns your pick into a basket of real companies, part from what major ETFs hold and part from what real investors hold. You set the ratio, and the whole basket goes through the broker you already use.
Free to start on the web, iPhone, and Android.
Straight from the App Store listing.
Three steps to your first portfolio
Pick your themes
Choose the industries and ideas you believe in, from 350+ themes. No brokerage needed to start.
Set your blend
Decide how much of the basket follows what major ETFs hold and how much follows what real investors hold. One slider, your call.
Invest through your broker
Connect the account you already trade with and place the whole basket in one order, when you are ready.
All ETF. All crowd. Or anywhere between.
Both sides of the blend hold real companies. The crowd side comes from what investors here actually hold, synced from their connected brokerages and aggregated anonymously. The ETF side draws its companies from major ETF portfolios to keep the base broad and steady. Slide to either extreme or any split you like, tilt toward the themes you pick, and try it right here:

MarketPlays is not a brokerage. It is the layer where you build the blend and have the conversations. Your money stays in the account you already trust.

Anonymous aggregation
Holdings are aggregated anonymously into the crowd portfolio. Your account details are never shared.
Quotes may be delayed. MarketPlays is not an investment adviser.
Investing is better with a community
Every stock and sector on MarketPlays has a discussion attached. Ask what others see in a company, share what you find, and follow the topics you care about, in the same place you invest.
Common questions
Are these real portfolios?
Yes. Positions are synced from connected brokerage accounts through our SnapTrade integration, so your portfolio reflects what you actually hold instead of numbers you typed in.
How does the blend work?
Your personal portfolio holds real companies from two sources: an ETF side drawn from what major ETFs hold, and a crowd side drawn from what investors here actually hold. The default split is 40 percent crowd and 60 percent ETF, and you can shift it with one slider. Free members can change the blend once every 30 days, with changes applying at the next weekly refresh. Pro members can change it any time and changes apply right away.
Is MarketPlays a brokerage?
No. MarketPlays connects to the brokerage you already use. Your money and your positions stay at your brokerage, and orders are placed through the account you connect.
Does MarketPlays pick stocks or trade for me?
No. Nothing trades without you placing the order, and the AI research explains a stock, covering the bull case, the bear case, key risks, and upcoming catalysts, without ever picking it for you. MarketPlays is not an investment adviser, and nothing in the app is personalized advice.
