$1.5B
Annual recurring
$337.5M
Personnel

⚡ Cost Scenarios
📊 Baseline (baseline) $337.5M/yr
92.5% probability / year
Normal operational year with no major incidents: routine ward maintenance, containment operations, R&D, replacement allowance and recurring logistics.
no breaches standard operations scheduled research
🚨 Minor Incident $347.5M/yr
5.0% probability / year +$10.0M vs baseline
Localized ward failure or small gateway breach requiring emergency response, short-term replacements and localized diplomatic/legal expenditures.
localized breach at a single gateway temporary ward failure limited diplomatic payout
🚨 Major Breach $837.5M/yr
0.5% probability / year +$500.0M vs baseline
Large-scale containment failure or coordinated breach (e.g., hostile action at NK or multi-site failure) requiring full mobilization, capital replacements, large diplomatic/covert expenditures and potential reconstruction.
coordinated multi-site breach loss of central vault capacity major diplomatic/military crisis
🚨 Exploration Scale Up $487.5M/yr
2.0% probability / year +$150.0M vs baseline
Deliberate decision to scale exploration and sustained presence inside SCP-4516-B (expanded expeditions, bases, long-term research expansion).

📋 Confidence Notes
Analyst provided detailed line items with ranges allowing midrange estimates, but SCP-4516's anomalous scale, geopolitical uncertainty (NK site), and open-ended exploration costs introduce significant uncertainty; medium confidence reflects reasonable mapping of ranges but substantial tail risk.
