The Zestimate King: How Jeremy Wacksman is Turning Real Estate’s "Internet Porn" into a Billion Transaction Machine

LAS VEGAS — Jeremy Wacksman is scrolling through his own past on his iPhone. On his Zillow account, the 48-year-old CEO has "favorited" every home he has ever lived in. He points to a 2,500-square-foot house in the Cincinnati suburbs where he grew up. In 1997, his father sold it for $227,000. Today, Zillow’s proprietary Zestimate values it at $700,000.

"The doors weren’t red when we lived there," Wacksman notes, squinting at the street view.

It is a fitting hobby for the man leading the "Google of Real Estate." Since its launch in 2006, Zillow has done to homebuying what Uber did to taxis: it disrupted an opaque, expert-guarded market and handed the data to the people. Today, Zillow reaches 243 million monthly users—quadruple its nearest competitor. It is so addictive that Saturday Night Live famously parodied it as "internet porn" for millennials.

From Data Disruptor to Transaction Titan

When Wacksman left Microsoft for Zillow in 2009, the mission was "Power to the People." By providing sales histories and Zestimates for free, Zillow stripped real estate agents of their role as "information arbiters."

However, the business model has a surprising twist: 70% of Zillow’s $2.2 billion revenue comes from the very agents it disrupted. They pay Zillow for leads. Now, Wacksman is shifting the strategy again. He doesn't just want to be a lead-generation site; he wants to facilitate the entire transaction.

Under Wacksman’s leadership, Zillow has moved aggressively into the "plumbing" of real estate:

Acquisitions: Bought Follow Up Boss (a massive CRM) for $500 million.

The Flex Program: Zillow now takes a "success fee"—15% to 40% of an agent’s commission—aligning the company’s profit directly with closed deals.

Tech Integration: Adding home tour reservations and agent-buyer messaging to create a seamless "housing super-app."

The "Gorilla" in the Room

Zillow’s dominance has painted a target on its back. In 2024 and 2025, the company has faced a barrage of antitrust litigation. The FTC and several state attorneys general have labeled it a "gorilla-sized company," alleging anticompetitive practices.

Wacksman, dressed in "aggressively business casual" navy knitwear and Zegna sneakers, remains unfazed by the nine-figure legal threats. "As you’re an innovator and changing, there’s naturally a sharper focus on you," he says with a smile.

The 2026 Outlook: A Stalled Market

Despite Zillow's tech prowess, Wacksman faces a macroeconomic wall. In 2024, US home sales hit a 30-year low. As we move into 2026, Zillow’s economists expect only "very modest" growth. The problem isn't a lack of interest—it's a lack of supply.

"Affordability challenges" are keeping people from moving, a stark contrast to 2003 when Wacksman bought his first starter home for $280,000. Today, he is lobbying Washington for policy reforms to encourage building.

Whether the market moves or stays stalled, Wacksman is betting that Zillow will be the one holding the keys. "If you’re not willing to take a big swing," he says, "you risk missing whatever the next wave is."
