Estimated up-front (one-time) containment and infrastructure costs are on the order of $8.76 billion, driven primarily by construction of a large perimeter reef wall, platform construction, fleet procurement and major capital equipment. Annual recurring operations, maintenance, staffing and monitoring are roughly $402 million per year, driven by structural maintenance, continuous monitoring/research, vessel operations and legal/cover costs.

⚡ Cost Scenarios

📊 Baseline (baseline) $402.0M/yr

87.5% probability / year

Normal uneventful year with scheduled maintenance, monitoring and research only.

🚨 Minor Incident $452.0M/yr

10.0% probability / year +$50.0M vs baseline

Localized breach/damage (storm, limited structural failure or single-asset loss) requiring emergency repairs and limited replacement of equipment.

🚨 Major Breach $652.0M/yr

2.0% probability / year +$250.0M vs baseline

Significant containment failure or attack by internal organisms causing loss of multiple assets and widespread structural damage requiring major repairs and asset replacement.

🚨 Anomalous Expansion $1.9B/yr

0.5% probability / year +$1.5B vs baseline

SCP-850 exhibits significant expansion or unpredictable behavior that forces rapid scale-up of containment (additional wall construction, new fleet and urgent research facilities).

📋 Confidence Notes

Estimates are order-of-magnitude and highly sensitive to the true size/depth/behavior of the anomaly; key drivers (reef circumference, seabed depth, and anomalous growth) are poorly constrained, so overall confidence is low.
