New AI-compute cryptocurrency Pearl sparks a GPU mining rush but profitability is already sliding — RTX 5090 daily revenue has halved to $17.19 since April

Pearl (PRL), an AI-compute cryptocurrency, launched its mainnet in late April 2026 and quickly drew miners after a Together AI partnership announcement.

The network uses matrix-multiplication work from AI workloads to secure the chain, but mining is limited to Nvidia GPUs and mostly trades on low-liquidity exchanges.

As more miners rented cloud GPUs like the RTX 4090 and RTX 5090, network difficulty climbed and profitability fell fast.

Tracker hashrate.no estimates RTX 5090 revenue at $17.19 per day, down about 49% from $33.80.

The rapid drop shows how quickly GPU mining booms can cool once participation rises and block rewards trend lower.
