Institutional Crypto Flows — Bitcoin ETF & Corporate Treasury Tracker

Institutional Crypto Flows tracks daily Bitcoin ETF flows for all US spot ETFs (IBIT, FBTC, BITB, ARKB, GBTC, and 10+ others) using Farside Investors data — the most widely cited public source for institutional BTC demand. Get per-fund daily flows, 7d/30d cumulative flows, flow trend classification, consecutive streak counts, and market-level institutional sentiment. No API key required.

Bitcoin ETF flows are the most direct institutional demand signal available: when BlackRock's IBIT sees $500M+ of daily inflows, institutions are actively accumulating. This actor structures that daily signal for trading bots, portfolio dashboards, and macro research.

Why use Institutional Crypto Flows?

1. Institutional accumulation/distribution signal — Total daily ETF net flow is the cleanest measure of institutional BTC demand. Consecutive inflow streaks with growing volumes = accumulation regime; outflows = distribution. Use as a macro filter for position sizing.
2. ETF market share analysis — Track which fund (IBIT vs FBTC vs ARKB) dominates flows each week. BlackRock's IBIT dominance vs Fidelity's FBTC growth tells a story about institutional preference and AUM trajectory.
3. Streak-based momentum — consecutive_inflow_days streaks above 5–7 days have historically preceded BTC price acceleration. Monitor streak lengths as momentum indicators.
4. Flow-based reversal detection — When strong_outflow appears after a run of inflows, it often precedes price correction. The flow_trend field gives you this classification automatically.
5. Corporate treasury monitoring — Falls back to bitcointreasuries.net data when Farside is unavailable, providing corporate (MicroStrategy, etc.) and government BTC holdings as an alternative institutional demand lens.

FAQ

Is Farside data official or scraped? Farside Investors publishes the data publicly on their website as a free service to the crypto research community. This actor scrapes their published HTML tables — no authentication or API key required.

How current is the flow data? Farside updates daily after US market close. The actor fetches whatever is available at time of run; for same-day data, run after ~6–8pm ET.

What's the difference between flow_today_usd and AUM? flow_today_usd is the net new money in/out on a single day. aum_usd is the cumulative sum of all historical net flows since ETF inception — a proxy for total assets held.

Does GBTC always show outflows? GBTC (Grayscale) was originally a closed-end trust that converted to an ETF in January 2024. It charged higher fees than newer competitors, causing sustained outflows as investors rotated to lower-fee alternatives (IBIT, FBTC). This is a structural trend, not a signal to short GBTC specifically.
