Fidelity’s Bitcoin ETF draws $310.7M as spot funds stabilize after midweek selloff
Fidelity’s Bitcoin ETF saw an outsized inflow Friday as spot BTC funds rebounded from a steep midweek selloff, but the week still nearly ended negative. For allocators tracking institutional capital flows, the distribution of demand across multiple issuers signals whether the recovery is sustained or issuer-dependent.
- Fidelity’s FBTC drew $310.7 million Friday, nearly 2.9 times BlackRock’s IBIT inflow of $108.4 million that day.
- U.S. spot Bitcoin ETFs recorded $746.3 million in net withdrawals Tuesday and Wednesday combined, erasing most gains from the week.
- Weekly inflows totaled just $6.1 million, leaving the market barely positive after outflows surrounding the Federal Reserve’s 25-basis-point rate increase.
- $433M Net inflows to U.S. spot Bitcoin ETFs on Friday, September 18 alone
- $6.1M Total weekly net inflows across all U.S. spot Bitcoin ETFs for the full week
- 25bps Federal Reserve interest rate increase to 3.75%-4.00% on September 16
- $120.6M BlackRock’s IBIT accumulated inflows over the entire five-session week
U.S. spot Bitcoin exchange-traded funds stabilized Friday with $433 million in net inflows, according to Farside Investors, marking a second consecutive day of recovery after steep midweek losses. The session extended a partial rebound that began Thursday, but fell short of fully offsetting the $746.3 million withdrawn on Tuesday and Wednesday combined. CryptoSlate reported that Fidelity’s Wise Origin Bitcoin Fund led Friday’s inflows with $310.7 million, signaling a shift in the distribution of institutional capital across fund issuers.
Fidelity Emerges as Largest Single Contributor on Friday
Fidelity’s $310.7 million inflow on Friday dwarfed BlackRock’s contribution to the same session. BlackRock’s iShares Bitcoin Trust recorded $108.4 million, less than one-third of Fidelity’s total. Bitwise’s BITB, ARK 21Shares’ ARKB, and VanEck’s HODL also posted positive flows, indicating that demand was no longer concentrated in a single fund.
The shift reversed the pattern from earlier in the week, when BlackRock led Monday’s return to inflows while Fidelity played a secondary role.
Weekly Rankings Still Show BlackRock’s Broader Edge
Despite Fidelity’s dominance on Friday, BlackRock accumulated more capital over the full five-session week. IBIT drew $120.6 million compared to Fidelity’s $79.9 million across the period. This distinction matters because a single session cannot establish whether demand has genuinely broadened or merely shifted on one day.
The evidence suggests participation widened Friday, but sustained change in allocator behavior requires consistent patterns across multiple sessions.
Timing With Fed Rate Decision Adds Context But No Clear Causation
The midweek withdrawals coincided with the Federal Reserve’s decision on September 15 and 16 to raise its target range by 25 basis points to 3.75% to 4.00%, according to the Fed’s announcement. While the timing provides context for the selloff, available data does not establish that the policy decision directly caused either the outflows or the subsequent rebound.
The two-day recovery generated $592.5 million in combined inflows, nearly offsetting the $746.3 million lost Tuesday and Wednesday but leaving a $153.8 million deficit. Monday’s $159.9 million inflow had pushed the five-session total barely above zero before Friday’s gains, meaning the week ended with net inflows of only $6.1 million, underscoring how narrow the margin was between a positive and negative result.
Investors should watch the next several ETF sessions closely to determine whether Fidelity and smaller issuers sustain their contribution alongside BlackRock, or whether demand consolidates back around IBIT. The participation broadened on Friday and recovered most midweek damage, but one session cannot confirm whether allocators are genuinely diversifying their Bitcoin ETF positions or responding to a temporary dislocation.
The BlockWest read. Fidelity’s surge Friday is material for fund performance but signals uncertainty about where institutional capital settles long-term. BlackRock maintains the week’s net advantage, and a single day of diversified inflows does not prove the weekly concentration in IBIT has broken. The market remains vulnerable to reversal if outflows resume, given how close the week came to negative territory.
