BlackRock Inflows Couldn’t Salvage Bitcoin ETFs
Only four Bitcoin ETFs were active yesterday. Three funds witnessed losses, while BlackRock Bitcoin ETF (IBIT) recorded the only inflows worth $409.72 million. Ark 21Shares Bitcoin ETF (ARKB) had the highest outflows worth $132.05 million. Fidelity Bitcoin ETF (FBTC) also forfeited over $100. The fund lost $123.66 million, while Grayscale Bitcoin ETF (GBTC) forfeited $39.06 million.
Yesterday’s losses reduced Bitcoin ETFs total value traded from $2.74 billion to $2.58 billion. The net assets also dropped from $121.84 billion to $121.47 billion.

Despite the outflows, Bitcoin ETFs cumulative net inflows slightly appreciated from $41.40 billion to $41.51 billion.

The State of Wisconsin Dumps BlackRock Bitcoin ETF Shares
Earlier today, Crypto2Community reported that the State of Wisconsin Investment Board (SWIB) has sold off all its stake in IBIT. SWIB disclosed the sell-offs in a new filing presented to the United States Securities and Exchange Commission (SEC) on May 15.
For context, SWIB controls the assets of the Wisconsin Retirement System. It realized about $321 million from selling its entire 6,060,351 IBIT shares in this year’s first quarter (Q1). Based on present market conditions, the sold stakes have appreciated to over $350 million. Moreover, before now, SWIB had dumped all its $63.7 million stakes in Grayscale’s Bitcoin Trust (GBTC).
