Majestic Labs AI unveils Prometheus server with 1,000x Nvidia GPU memory capacity

Majestic Labs AI has unveiled Prometheus, a server with 1,000x the memory capacity of NVIDIA GPUs. The announcement is relevant to Polymarket’s largest-company-by-market-cap contracts, where NVIDIA being the largest by market cap on June 30 sits at 92% YES.

Market reaction

NVIDIA’s June 30 odds are unchanged at 92% YES. The December 31 market trades at 0.9% YES, also unchanged over the past week. Combined daily volume in NVIDIA’s largest company by market cap market is $101,970 in face value, with only $475 in actual USDC traded. It takes just $275 to move the December 31 market by 5 points.

Why it matters

Majestic Labs is targeting the “memory wall,” the bottleneck that limits how large a model can run on a single server. If Prometheus delivers on its specs, it could reduce dependence on NVIDIA’s GPU-centric architecture for large-scale AI inference and training. That said, Prometheus has no announced shipping date or benchmark results yet, so the practical threat to NVIDIA’s revenue remains speculative.

What to watch

At 9¢, a YES share for NVIDIA being the largest by December 31 pays $1 if it resolves, a 11.1x return. For that bet to work, traders would need to believe NVIDIA’s competitors won’t gain substantial ground by year’s end. Watch for NVIDIA responses (new hardware announcements, partnership deals) and any US export restrictions on semiconductors that could affect NVIDIA’s revenue outlook.
