Solana perps open interest hits $500 million after network upgrade

Solana perpetual futures open interest reached $500 million, a nine-month high, after the July 29 network upgrade drew traders back to on-chain derivatives venues.

The milestone was flagged by @SolanaFloor, a crypto commentator on X, and confirmed by derivatives data tracked across Solana-based platforms. Galaxy Research's weekly brief separately highlighted PhoenixTrade, the Solana-based perps exchange built by Ellipsis Labs, which hit a record open interest of $10 million to $11 million in late July after launching its Flight Club incentive program.

Total open interest for SOL token futures across all platforms, including centralized exchanges, sat near $1.8 billion in early August, up from $429 million in May. Solana-based perp venues accounted for roughly 3 percent of total open interest market share and about 2 percent of volume market share during Q1 2026, down from peaks hit in 2024.

The rebound comes as traders return to Solana's derivatives venues after a relatively quiet stretch, but the network still commands a small slice of a market dominated by Hyperliquid, which reports more than 70,000 daily users versus PhoenixTrade's roughly 1,300.

PhoenixTrade's Flight Club drives record activity

PhoenixTrade launched its Flight Club incentive program, distributing $420,000 to users, which pushed the platform's daily trading volume to $67.1 million. The program lifted the exchange's open interest to between $10 million and $11 million, a roughly 25 percent jump from its previous high of $8.8 million set in June.

The incentive-driven growth mirrors a broader pattern on Solana, where trading activity has historically responded to rewards programs. The end of Jupiter's annual airdrop and the Drift hack earlier in the year removed enticements for trading, contributing to a decline in Solana's perps market share during Q2 2026 despite a volume surge.

Solana perps still trail Hyperliquid by wide margin

Solana's on-chain perps ecosystem has been building steadily but still operates in the shadow of more established platforms. Hyperliquid, which runs its own appchain, continues to dominate the decentralized perpetual futures market by a wide margin in both volume and open interest.

The network hasn't been without setbacks. Earlier in the year, the Drift hack dented trader confidence across Solana's DeFi ecosystem. Drift had been one of the larger perpetual futures platforms on the network, and the incident served as a reminder that smart contract risk remains a persistent concern for on-chain derivatives venues.

The elevated open interest also carries risk. If SOL price reverses, leveraged positions could trigger liquidation cascades that push prices lower. SOL traded at $73.63 as of Aug. 7, up 1.06 percent on the day. Traders should also watch for whale movements and large wallet transactions, which could provide early signals on whether the current momentum is sustainable.

The $500 million open interest milestone, while modest relative to Hyperliquid's scale, marks a turning point for Solana's derivatives market. If the network upgrade delivers sustained improvements in throughput and reliability, and if incentive programs continue to attract traders, Solana's perps venues could capture a larger share of the decentralized derivatives market in the coming quarters. The next test will be whether open interest holds above $500 million as the initial post-upgrade enthusiasm fades.
