Perps Open Interest: DEX vs CEX
A comprehensive breakdown of perpetual futures open interest across decentralized (DEX) and centralized (CEX) platforms. As of June 2026, total perps OI stands at ~$115.9B — CEX platforms account for ~$96.5B (83.2%) while onchain DEX protocols hold ~$19.4B (16.8%). Hyperliquid dominates the DEX side with ~$8.9B OI, making it the only DEX to rival mid-tier CEXes. Binance alone commands $21.4B — more than the entire DEX ecosystem combined.
🥊 DEX vs CEX Split
CEX platforms hold a commanding 83.2% share of all perps OI. Despite rapid DEX growth led by Hyperliquid, onchain perps still represent only 1-in-6 dollars of open interest. The gap narrowed in 2025 but CEX infrastructure advantages in execution speed and liquidity depth remain significant barriers for DEX expansion.
📊 DEX Open Interest Breakdown
Hyperliquid dominates onchain perps with ~$8.9B OI — roughly 46% of all DEX OI. TradeXYZ ($3.1B) and Aster ($1.8B) are distant runners-up. Notably, Polymarket ($424M) and Kalshi ($792M) also appear in the DEX OI data reflecting prediction market positions. The long tail includes 90+ protocols, but the top 5 account for the vast majority of activity.
🏦 CEX Open Interest Breakdown
Binance controls $21.4B in perps OI — 22% of the global total and 4x larger than the entire DEX ecosystem. Bybit ($9.6B), MEXC ($8.4B), Gate ($7.9B), and OKX ($6.2B) round out the top 5. Deribit ($2.9B) stands out as the dominant options/perps venue for institutional BTC and ETH positioning. Combined, the top 5 CEXes account for ~$53B — more than 45% of all global perps OI.
🔭 All Platforms Combined — OI Leaderboard
Across all 50+ platforms tracked (CEX + DEX), Binance sits alone at #1 followed by Bybit, then Hyperliquid as the highest-ranked DEX at #3 — a remarkable achievement for an onchain venue. The combined leaderboard shows DEX protocols beginning to break into the top tier, with 4 DEXes in the top 15 platforms globally.
