Hey team,

We announced this morning that Rocket has entered into an agreement to acquire Redfin, the leading brand in real estate.

On a personal level, I have deep love for Redfin. I spent several years in Seattle where the company is based, and I have admired the way it influenced the evolution of real estate over the years.

This acquisition shows our commitment to creating an AI-driven homeownership platform and our unwavering focus on purchase.

Before I dive into more of the details and vision, I want to take a step back and unpack the why.

Our north star metric is profitable market share growth, grounded in our mission to Help Everyone Home.

We heard from Brian Brown during ACM about the massive opportunity we have in one of the largest and most fragmented markets in the country. No company has double-digit market share in mortgage, one of the reasons it’s ripe for disruption.

Let’s take a moment to look at why Redfin is such a great fit for Rocket. I want to start with culture because our ISMs and values are foundational in everything we do.

I have gotten to know Glenn Kelman, Redfin’s CEO – who has led the company since 2005, just a year after it was founded. Redfin values innovation, doing the right thing and the team is obsessed with finding a better way.

Redfin has 4,500 team members, including 2,200 brokered real estate agents who support clients across the country.

Through this acquisition, we will form a scaled homeownership platform from home search portal and real estate agent network to mortgage, title and servicing.

Redfin is the largest online brokerage, with 50 million monthly visitors to its portal. This, combined with its broker agents, strengthens our position in important areas at the top of our funnel – driving more clients into the Rocket ecosystem and fueling the growth of purchase.

There are many reasons to be excited for what’s ahead, but I want to note that today’s announcement was that we entered into an agreement. We expect the transaction to close in the second or third quarter of 2025. Until then, we will continue to operate as two separate companies.

I know you probably have a lot of questions about what’s ahead. Please read through our FAQ to find answers to questions that may be on your mind. We won’t have all the answers yet, but we will communicate openly throughout this entire process.

In closing, I want to reiterate that the most important part of Rocket is our people and culture. Through all our evolutions across our 40-year history, that has been our constant and it will remain that way.

Onward,

-varun
