True Cost Beyond Hourly Rate: Electricity Context
The hourly rate is only part of the total cost of GPU compute. At the U.S. national commercial electricity average of 12.15¢/kWh, an H100 SXM5 (700W TDP) running at a typical data center PUE of 1.58 adds $0.1344/hr in electricity overhead per GPU — before accounting for cooling, networking, or storage.
For a cluster of 8× H100s running 24/7 for a month: electricity adds approximately $774/month to your infrastructure cost.

Market Intelligence: What AI Teams Are Querying This Week
Based on 5 GPU cost queries on GridStackHub.ai this week, H100 pricing and B200/Blackwell availability remain the top concerns. The emerging pattern: teams are comparing spot vs. on-demand economics as H100 spot rates continue to compress downward from Blackwell supply increases.

Methodology
The GridStackHub GPU Cost Index is computed from daily automated scraping of 31+ provider pricing pages. On-demand pricing only (spot tracked separately). WoW delta compares current 7-day average with prior 7-day average. MoM delta compares with 30-day prior average. All prices in USD/GPU/hour. Vague GPU-slice products (e.g., Vultr vGPU) excluded from index calculations.

What is the cheapest H100 GPU cloud provider in 2026?
According to the GridStackHub GPU Cost Index for May 3, 2026, the cheapest on-demand H100 is $1.7900/hr on Shadeform. Prices update daily as providers adjust rates.
How does electricity cost affect total GPU cloud cost?
At the U.S. commercial electricity average of 12.15¢/kWh and a data center PUE of 1.58 (Uptime Institute 2025 benchmark), an H100 SXM5 (700W TDP) adds approximately $0.1344/hr in electricity overhead. This is typically absorbed by cloud providers in their hourly rate, but colocated infrastructure operators pay this directly.
How often does the GridStackHub GPU Cost Index update?
The underlying pricing data updates daily via automated scraping of 31+ provider pricing pages. The weekly index aggregates this into trend analysis every 7 days, published every week.
