Castle Labs reported that onchain RWA perpetual trading volume climbed from less than $1 billion in October 2025 to more than $120 billion in August 2026, representing roughly 120x growth in under a year. RWA perpetuals accounted for about 20% of total onchain perpetual volume at one point in July and around 12% to 13% in most months.
Why it matters
Monthly volume has remained above $100 billion since June. That sustained run rate makes RWA perpetuals a material segment of onchain derivatives, not just a one-month spike.
Market impact
Current open interest stands at approximately $4.9 billion, with TradeXYZ and Variational accounting for nearly 90%. The rapid volume growth is paired with concentrated open interest. The key market read is whether volume remains above $100 billion and whether open interest broadens beyond those two platforms.
