The county went looking for four points of diversification after the housing crash. It ended up with a budget that data center revenue now covers outright, and siting hearings elsewhere have become fiscal arguments as a result.

Compiled by The Product DeskSomething wrong?How this is made
The fix Buddy Rizer found was already lying in the ground. Loudoun had AOL's former headquarters, miles of fiber left over from the dot-com bust, an internet exchange point and a local utility able to serve it [10]. Estimates put as much as 70 percent of the planet's internet traffic through the county at its peak [11]. Re-tenanting an asset like that behaves differently from building an industry from scratch, because the second campus is easier to win than the first, and the county now holds about 250 data centers across a small portion of its 515 square miles, the densest concentration in the world [4].
Which is how a four-point plan became a majority. Rizer's stated target was commercial at something like 23 percent of revenue, up from about 19 [2]. The county now sits just over half [3], more than 27 percentage points past the number it was aiming at [14]. The Verge's account traces the growth deal by deal, without pinpointing who chose the larger figure.
The pitch was diversification. What Loudoun actually did was move the concentration: in 2007, more than 80 percent of revenue came from residential real estate, and that market had just broken [1]. The replacement dependence is a single tenant class whose appetite is set by how much compute the generative AI buildout needs.
Residents got paid for it, in terms that are hard to argue with. The county built 22 new schools in 15 years [7], close to one and a half a year [17], and the real property tax rate fell from about $1.29 to 80 cents per $100 of assessed value since 2008 [6], a cut of roughly 38 percent [15]. Set against that, data center revenue alone came in $35 million above the entire county operational budget in 2024 [5]. As a result, the next application is not really a zoning matter for the board so much as a question about which line item absorbs the difference if it is denied.
Revenue share is the metric that travels well and explains the least. It says nothing about whether the households paying the lower rate would approve the next campus. What the reporting actually shows on that side is thinner and more particular: residents who had not heard their county's nickname until recently [12], and residents who now think about data centers daily because of the hum off the deck or the transmission towers overhead [13]. The number a board would actually want is the share of households that would approve the buildout again after five years of living beside it, and no one publishes it.
So the two questions worth writing down before the next hearing are what share of revenue comes from one class of buyer, and how many years it would take to replace that buyer if the orders stopped. Loudoun's answer to the first is more than half [3]. The second remains unanswered, and the counties copying the pitch into markets where economic developers now outnumber data center companies at the conferences [9] are copying the first answer without it.
Ranked by verification strength, evidence, and original report placement.
In 2007, more than 80 percent of Loudoun County, Virginia's revenue came from residential real estate, and Buddy Rizer, who had joined the county's economic development authority, was tasked with finding the county a new way to make money as the housing bubble burst.
The goal at the time was to raise the commercial tax base from about 19 percent of revenue to something like 23 percent, Rizer recalls.
Today, just over half of Loudoun County's tax revenue comes from commercial sources.
Loudoun County is home to about 250 data centers, spread over a small portion of its roughly 515 square miles, the densest concentration in the world.
Tax revenue from data centers alone exceeded Loudoun County's operational budget by $35 million in 2024.
The real property tax rate for Loudoun residents has declined from about $1.29 to 80 cents per $100 in assessed value since 2008.

Evidence-backed comparisons of source perspectives and observed adoption signals. Read the methodology
Which Builder, Operator, and Investor concerns the observed source mix emphasized—not a truth score.
Evidence, demonstrated adoption, hype gap, incentives, and confidence are assessed independently, each on its own current evidence. How these are measured.
One outlet, one insider, one outside number
Every fiscal claim in this story — the 19-to-23 percent goal, the commercial share above half, the $35 million overshoot, the tax rate down to 80 cents, the 22 schools — reaches us through a single Verge feature, and inside it largely through Buddy Rizer, who is explicitly quoted as recalling the target. Pew's 3,000-and-1,500 count is the only figure anchored outside the story's own cast, and the 70 percent traffic estimate has no owner at all. The specifics are concrete and internally consistent; nobody has checked them against a county budget document in our coverage.
Concrete already poured
Whatever you think of the framing, this is not a forecast about buildings that might appear. About 250 facilities are running in one Virginia county, Pew counts 3,000 nationally with 1,500 more moving, and the local consequences are physical enough that residents identify them by sound and sightline. Two states have already begun slowing approvals, which is itself evidence the deployment is large enough to hit a constraint.
Restrained, with two soft edges
The arithmetic mostly speaks for itself and The Verge lets it — a target of 23 percent, an outcome above 50, a budget covered outright. Two things run ahead of the evidence: the ownerless claim that up to 70 percent of the planet's traffic once crossed this county, and the residents' 'canary in the coal mine' self-description, which asks Loudoun's particular inheritance of AOL-era fiber and a friendly utility to stand in for every county's future. Small overhang on a mostly sober account.
The architect narrates his own record
Two pulls shape what we read. Rizer is the county's economic development authority, and the numbers proving the strategy worked — the target, the commercial share, the conference standing — are his to characterise; he is also the story's chief guide to whether the boom went too far. The Verge, for its part, is writing a feature that turns on backlash, and the residents' hum-and-towers material carries the second half. Neither interest is hidden, and no operator or utility voice is present to pull the other way.
Trust the direction, verify the digits
Single-publisher coverage of verifiable public finance is an odd combination: the claims are exactly the kind a county budget would settle, and none of them has been settled here. We hold the shape of the story with some confidence — the base shifted, rates fell, salience rose, other states are hesitating — and hold each individual dollar figure loosely until a second account or a primary document appears.
