Fidelity surge brings in $310M BTC saving Bitcoin ETFs from a disastrous week

U.S. spot Bitcoin exchange-traded funds drew $433 million of net inflows on Friday, Sept. 18, according to Farside Investors. The session extended the market's rebound to a second day, but it did not fully repair the withdrawals recorded earlier in the week.

In the Farside data, Fidelity's Wise Origin Bitcoin Fund, or FBTC, supplied $310.7 million on Friday. That was nearly 2.9 times the $108.4 million added by BlackRock's iShares Bitcoin Trust, known as IBIT. Bitwise's BITB, ARK 21Shares' ARKB and VanEck's HODL also posted smaller positive flows, giving the session more than one meaningful source of demand.

The issuer split marked a reversal from the earlier rebound. Monday's return to inflows was led by BlackRock, with Fidelity playing a secondary role. By Friday, Fidelity was the largest contributor while IBIT remained positive.

The broader two-day picture was less decisive. Thursday and Friday generated $592.5 million of combined inflows after investors withdrew $746.3 million on Tuesday and Wednesday. The rebound therefore left a $153.8 million gap against those two losing sessions.

Monday's $159.9 million inflow was enough to push the five-session total barely above zero. The week ended with $6.1 million of net inflows, underscoring how little separated the recovery from a negative weekly result.
