What Is the Largest Real Estate Brokerage in the US?
By agent count, Keller Williams Realty is the largest real estate franchise in the US with over 180,000 agents, followed by RE/MAX and Century 21. But when you look at brand recognition, global reach, and revenue, industry leader Realogy (which owns Coldwell Banker, Century 21, and Sotheby's International Realty) dominates the landscape. For home buyers and sellers, what matters is not just which brokerage is the biggest, but which one has the best local agent working for you.

The Top Real Estate Brokerages in the US
The US real estate market is served by several major brokerage brands, each with its own strengths. Here is how the top companies compare:
Top US Real Estate Brokerages by Agent Count
- Keller Williams Realty - 180,000+ agents. Known for aggressive training and a strong company culture focused on agent success.
- RE/MAX - 130,000+ agents. Globally recognized for its agent-centric model and strong marketing presence.
- Century 21 - 130,000+ agents. One of the most recognizable brands with a strong franchise network.
- Coldwell Banker - 100,000+ agents. Founded in 1906, one of the oldest and most prestigious brands. Part of Realogy, the largest residential real estate services company in America.
- Berkshire Hathaway HomeServices - 50,000+ agents. A relatively newer brand backed by Warren Buffett's Berkshire Hathaway, known for luxury and integrity.
What "Largest" Really Means for You
When you ask "what is the largest real estate brokerage," the answer depends on how you measure it. Keller Williams has the most agents. Realogy (parent company of Coldwell Banker, Century 21, and Sotheby's) generates the most revenue. But for a home buyer or seller, what matters is which brokerage gives you the best shot at a successful transaction.
A large brokerage offers advantages: more resources, better technology, a larger network of agents, and stronger brand recognition. Coldwell Banker, for example, operates in over 40 countries and has more than 3,000 offices worldwide. That global reach means your listing gets exposure far beyond your local market.
But the most important factor remains the individual agent. A great agent at any of the top brokerages will deliver better results than an average agent at the biggest one. That is why it matters who you choose, not just which brand they work for.
Why Coldwell Banker Stands Out
Coldwell Banker has been a dominant force in real estate since 1906. The company's longevity speaks to its stability and trustworthiness. As part of Realogy, Coldwell Banker agents have access to industry-leading technology, marketing platforms, and a vast referral network that spans the globe.
For South Florida specifically, Coldwell Banker Realty has a strong presence with offices throughout Delray Beach, Boca Raton, and the surrounding coastal communities. That local footprint means agents like Ryan Parker can offer the perfect combination of global brand power and hyper-local market knowledge.

What to Look for in a Brokerage and Agent
Whether you choose an agent from Coldwell Banker, Keller Williams, or another top firm, here is what matters most:
- Local market knowledge. Does the agent know your target neighborhood inside and out?
- Communication style. Will they respond quickly and keep you informed?
- Track record. Recent sales, testimonials, and experience in your price range.
- Marketing approach. How will they market your home or help you find one?
- Negotiation skills. Can they protect your interests and get the best deal?
