Bitcoin has seen a significant increase in bullish momentum this week, with the price rising from $78,000 to $82,855. The flagship cryptocurrency has pulled back from the region’s highs but has not yet shifted into a bearish structure. Interestingly, recent on-chain analysis shows a significant increase in derivatives activity in the Bitcoin market.
Bitcoin open interest rises on major exchanges
In a recent Quicktake post on the CryptoQuant platform, anonymous analyst Darkfost revealed an interesting change in Bitcoin derivatives market participation. This on-chain observation is based on the open interest indicator.
Open interest represents the total number of active futures contracts held by traders in the market. An increase in open interest is often interpreted as a signal of new capital entering the derivatives market, especially during periods of strengthening price momentum.
Notably, Bitcoin’s open interest has increased by the largest amount since early 2026 despite funding rates remaining in negative territory, as they have been for the past several weeks.
According to Darkfost, the recent growth in Bitcoin’s open interest has already surpassed Bitcoin’s previous all-time high set in 2025. Therefore, it has become increasingly clear that market participation across exchanges is indeed positive.

Binance sees $2.5 billion in open interest, leading other major exchanges
The cryptocurrency analyst went on to highlight Binance’s role in the ongoing dynamics. As Darkfost explains, Binance, the world’s leading cryptocurrency exchange by trading volume, holds approximately 34% of the market share.
As of May 5, the exchange reported an average monthly open interest of approximately $2.5 billion. The Quicktake post also cited other exchanges, with Gate.io reporting open interest growth of approximately $1.75 billion.
Bybit then followed in the open interest rankings with an average open interest of about $1.15 billion. According to Darkfost, these figures recorded by the quoted exchanges reflect growing optimism in the Bitcoin market, contrary to the situation seen at the beginning of the year.
As optimism grows, traders typically increase their risk exposure once again. However, Darkfost noted that this could make the BTC market more vulnerable. Large clusters of long or short positions become vulnerable to liquidation events.
When prices move rapidly for overly leveraged traders, forced liquidations can accelerate volatility and amplify price movements in both directions. Therefore, while an increase in open interest could help the Bitcoin price, market participants should be wary of sudden volatility spikes.
As of this writing, Bitcoin is valued at approximately $80,265, up 0.5% from yesterday.
