On May 20, 2025, Bitcoin price crossed the $105,000 mark again. During the intraday session, Bitcoin (BTC) reached $107,108 before closing above the $105,000 threshold. This price move triggered increased capital inflow into Bitcoin ETFs.
According to SosoValue, spot Bitcoin ETFs listed in the U.S. recorded a total daily net inflow of $667.44 million. This was the largest single-day inflow since May 2 and marked the fourth consecutive day of positive ETF inflows.
As of the latest data, Bitcoin trades at $105,543. Its 3% daily increase aligned with growing institutional activity, which remains visible across ETF and derivatives markets.
BlackRock IBIT Tops Bitcoin ETF Inflows
BlackRock IBIT led the inflow chart on May 20. The ETF attracted $305.92 million in one day, raising its total net inflows to $45.86 billion. This was the highest among all spot Bitcoin ETFs that day.
Fidelity FBTC followed with $188.08 million in net inflows. Its cumulative net inflows have now reached $11.78 billion. These two ETFs—BlackRock IBIT and Fidelity FBTC—accounted for the majority of capital movement during the session.
Other ETFs contributed smaller amounts to the overall $667 million inflow total. The data confirms continued institutional interest in Bitcoin ETFs, especially on days with strong price levels.
BTC Futures Open Interest Reaches 2025 Peak
Open interest in BTC futures also increased. Coinglass reports that futures open interest rose to more than $70 billion on May 20. This was the highest value in 2025. It reflected a 1% rise over the last 24 hours.
When both price and open interest climb together, it usually indicates new capital entering the market. The rise in BTC futures open interest shows that traders are opening new contracts as Bitcoin price gains momentum.
Volume remained stable across major derivatives platforms. The steady trading activity in futures supports the trend observed in the spot Bitcoin ETF space.
BTC Call Options Demand Rises in Derivatives Market
BTC call options also saw increased demand. According to Deribit, open interest in BTC call options rose on May 20. Call options give traders the right to buy Bitcoin at a specific price within a set time frame.
This increase in call options activity occurred alongside price movement and ETF inflows. The derivatives market responded to Bitcoin’s recovery of the $105,000 level with renewed positioning.
Together with spot and futures data, the rise in BTC call options adds to the picture of expanded market participation. These changes in options volume came on the same day as major ETF inflows, suggesting connected interest across markets.
