Blackwell Ultra GPU rental prices climb 17 straight days to a record high

Renting Nvidia’s top-tier AI hardware just got pricier for the 17th day in a row. As of October 15, 2026, on-demand rental prices for Blackwell Ultra (B300) GPUs have pushed to an all-time high. The figures come from Compute Desk, which runs an index built on verified rental transactions from US neocloud providers. Matthew Sigel, head of digital assets research at VanEck, flagged the trend and pointed to two drivers: strong demand for open-source models and supply constraints at Supermicro, which produces B300 systems. What the numbers show On-demand B300 rentals currently run around $7 to $10 per GPU-hour. Back in November 2025, the same compute cost approximately $4.55 per hour. That works out to a rise of approximately 64%. Anyone who budgeted for AI training runs last winter is probably revisiting that spreadsheet. The hardware itself has gotten more valuable too. Mid-October reports indicate the B300 has gained nearly 40% in value over the past three months. Compute Desk’s index matters here because GPU rental pricing has historically been opaque. Many deals happen privately, and posted list prices do not always match what customers actually pay. An index anchored to verified ...
