JPMorgan, a major US bank, disclosed holding 5.3 million shares of BlackRock Bitcoin ETF (IBIT) valued at $343 million as of Sept. 30, representing a 64% increase since June, according to a new filing tracked by Macroscope.

The bank’s expanded Bitcoin ETF position reflects the growing institutional adoption of crypto assets through regulated investment vehicles. Traditional financial institutions have increasingly embraced cryptocurrency exposure through ETFs as they offer familiar regulatory frameworks.

JPMorgan’s SEC filing also discloses positions in Bitcoin ETF options, indicating the bank has developed strategic hedging or trading activities in the crypto sector beyond its direct ETF holdings.
