U.S. spot Bitcoin ETFs pulled in $100.5 million in net inflows on May 14, 2024, extending a streak of positive demand that accelerated the following day when total inflows surged to $303 million, led by Fidelity’s FBTC fund with $131.3 million.
The $131 million figure circulating in initial reports appears to conflate two separate data points. According to unconfirmed reports, spot Bitcoin ETFs recorded $131 million in total net inflows on May 14, but no authoritative source supports that exact combination of date and figure.
Farside Investors’ daily flow tracker shows the actual May 14 total at $100.5 million across all U.S. spot Bitcoin ETF products. The $131.3 million figure instead matches FBTC’s single-fund inflow recorded on May 15.
FBTC Led a $303 Million Surge on May 15
Key Points
- Total spot Bitcoin ETF net inflows were $100.5 million on May 14 and $303 million on May 15
- Fidelity’s FBTC led all issuers with $131.3 million in single-day inflows on May 15
- BlackRock’s IBIT recorded $0 in net flows on May 15, while Grayscale’s GBTC added $27 million
The May 15 session marked a sharp acceleration. Total net inflows tripled from the prior day’s $100.5 million to $303 million, a two-week high, as Bitcoin moved above $66,000.
Fidelity’s FBTC captured the largest share at $131.3 million, making it the dominant flow driver. Grayscale’s GBTC, which had been a consistent source of outflows in earlier months, contributed a positive $27 million. BlackRock’s IBIT, typically the volume leader, was flat at $0.
Fund-Level Flow Breakdown
The divergence between FBTC and IBIT on May 15 stood out. FBTC alone accounted for more than 43% of the day’s total inflows, while IBIT’s flat reading suggested institutional rotation rather than broad-based new capital entering all products simultaneously.
Independent reporting from crypto.news confirmed FBTC’s leadership and the $303 million category total, corroborating the Farside data.
What the Two-Day Flow Pattern Signals for Sentiment
The back-to-back positive sessions on May 14 and May 15, totaling roughly $403.5 million in combined net inflows, came approximately four months after the SEC approved spot Bitcoin ETPs on January 10, 2024. The regulated structure created by that approval is part of a broader infrastructure expansion, as CME Group plans to launch market cap-weighted crypto index futures to complement spot ETF positioning.

Institutional Demand Remains Uneven
The IBIT flat reading on May 15 is a reminder that ETF inflows are not monolithic. On any given day, one issuer can dominate while others see zero or negative flows. This uneven pattern comes as broader regulatory efforts like the Clarity Act advancing through the Senate Banking Committee aim to provide more defined rules for digital asset markets.
Decrypt noted that the May 15 inflow print coincided with Bitcoin trading above $66,000, suggesting the flow activity tracked price momentum rather than acting as a contrarian signal. Meanwhile, research from Binance shows illicit crypto transactions represent under 1% of total activity, underscoring the legitimacy of the regulated ETF channel through which this capital is flowing.
The two-day sequence reinforces that spot Bitcoin ETF flows remain a meaningful, if volatile, indicator of institutional appetite in the months since the January approval.
