What happened Sometime later this year (or early next year), credit card payments processor Stripe is expected to make its debut on the public markets in an IPO -- and investors are excited. The surprising thing is that today, at least, they're not just excited about Stripe ... but about Shopify (NYSE: SHOP) stock as well, which is up 4.5% as of 3:45 p.m. EDT trading.

As The Wall Street Journal just reported today, Shopify participated in a funding event at Stripe in which bidders including mutual fund company Capital Group, venture capital firm Sequoia Capital -- and Shopify, too -- bought about $1 billion worth of Stripe shares prior to its IPO. Now what Admittedly, this still doesn't give Shopify anything like a controlling interest over Stripe, which was valued recently at about $95 billion. All told and including this latest investment, WSJ says that Shopify has invested only about $350 million in Stripe, which works out to less than a 0.4% interest in the company. Still, if Stripe explodes in value upon its IPO, that could yield a tidy profit for early investor Shopify -- and a nice boost to the value of investors' shares ... in both Shopify and Stripe. 10 stocks we like better than ShopifyWhen investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
