St. Louis is building its AI empire. Google and Amazon Web Services combined are pouring $25 billion into Montgomery County alone, with Google's campus ranking among the biggest data centers the company has ever constructed. Yet the moment city planners approved the $1.5 billion Armory Innovation Data Center in April, they made something crystal clear: crypto miners were not welcome at the table.
The contrast cuts deep. Missouri is racing to position itself as America's AI infrastructure backbone, luring tech giants with tax incentives and prime real estate. Meanwhile, crypto operations face an explicit ban written directly into zoning permits. This isn't a blanket moratorium on data centers. St. Louis codified the distinction between AI workloads and cryptocurrency mining straight into conditional use permits, treating them as fundamentally different animals.
The Numbers Behind the Bet
Across Missouri, 13 data center projects are either announced or in development. The statewide investment exceeds $25 billion. The Armory facility alone, sitting on 120 megawatts of capacity, is expected to generate roughly $432 million in tax revenue over a decade and create around 200 permanent jobs. Amazon's Montgomery County project should produce over 400 jobs. But here's the catch: fewer than 300 permanent positions are expected across all 13 facilities statewide.
The economics rest almost entirely on tax revenue and secondary effects from hosting major corporations. Direct employment gains are modest. The real prize for municipalities is the ongoing tax stream and the ecosystem that clusters around large compute operations.
Why Crypto Got Locked Out
St. Louis didn't just discourage crypto mining. The Armory permit came with additional teeth. Beyond the crypto ban, the city negotiated a $15 million community benefits agreement to ensure the surrounding neighborhood sees tangible returns from having a massive data center in its backyard. The message is clear: we want your infrastructure, your tax dollars, your jobs. We don't want your power-hungry mining operations.
The distinction matters. Data centers for AI training and inference demand consistent power but don't carry the same reputation baggage that crypto mining does. Cities are chasing the tech giant prestige and the stable long-term revenue. Crypto operations, by contrast, are volatile, energy-intensive, and politically toxic in many communities.
Missouri's approach suggests a growing pattern where jurisdictions will welcome AI infrastructure while actively rejecting crypto workloads. The state is essentially saying it wants the digital infrastructure race without the cryptographic mess.
