NVIDIA's latest GPU rental prices on the [Ornn Compute Price Index](https://ornn.com) hit $4.95 per hour this week, up from $2.31 in early March : a 114% surge in six weeks.[^1]

The price spread over prior-generation chips doubled from $0.28 to $1.80 per hour. The new chip is NVIDIA's B200 (Blackwell); the prior generation is the H200 (Hopper).

_The B200 spot market since launch, with model release dates marked._

The GPU market is becoming lucid - even if the fog hasn't lifted.

**1. Frontier model releases correlate with demand shocks**

The price spikes line up with major model launches. Every major model release since September 2025 preceded or coincided with jumps in B200 pricing.

GPT-5.5's expanded context window requires the memory headroom that only Blackwell provides.[^2]

The correlation isn't perfect. Supply shocks matter too. But the pattern is clear : newer models need newer chips.

**2. The gap between cheapest & most expensive providers is blowing out**

In September 2025, B200 prices across providers clustered tightly. Today the spread has more than doubled. Some providers still offer B200 at near-H200 prices. Others command scarcity premiums.

This bears the hallmarks of an opaque market with big supply/demand shocks. When is a hyperscaler receiving a new delivery? Which AI startup overbought capacity & is now selling at a discount? Opaque everywhere you look.

**3. The B200-over-H200 price gap collapsed, then recovered**

When B200 came to market in September 2025, it cost more per hour than H200. Buyers paid up for the extra memory & inference density.

By November, that gap collapsed to $0.28 as supply flooded the market. For a brief window, B200 & H200 reached near price parity.

Since February when GPT-5.3-Codex launched, the spread re-widened. The current $1.80 gap is back near launch levels.

The widening gap is also a depreciation signal : older chips lose value when new models demand new architectures.

_The spread collapsed in late 2025, then re-widened sharply in Q2 2026._

For cloud providers, pricing power is returning. After six months of margin compression, the sellers' market is back.

For AI startups, the spot market leads contract pricing by ~90 days. B200 likely settles above $5.00 for the summer.

For model builders, inference at the frontier is getting more expensive.

Inflationary demand outpaces deflationary algorithmic & chip improvements, but the fog of the GPU market continues.
