Crypto ETF Flow Tracker — BTC ETH Spot ETF Daily Net Inflows

Track Bitcoin ETF Flows in Real-Time — BTC, ETH & SOL Spot ETFs

Crypto ETF Flow Tracker scrapes daily net inflow and outflow data for every US-listed spot crypto ETF — BlackRock IBIT, Fidelity FBTC, ARK ARKB, Grayscale GBTC, and Ethereum/Solana ETF products — and delivers it as clean, structured JSON ready to plug into your trading bot, dashboard, or alert pipeline. No API key required. Runs in under 30 seconds.

Since the January 2024 SEC approval of US spot Bitcoin ETFs, institutional flow data has become the most reliable leading indicator for major price moves. This actor gives you machine-readable daily flow series for all three major crypto ETF categories, including cumulative AUM, day-over-day change, and Telegram alerts for spike events.

Why Use Crypto ETF Flow Tracker?

Institutional money moves markets before retail catches on. ETF flow data tells you what the smart money is doing:

• Catch early trends — sustained inflows ($500M+/day) have historically preceded 5–15% rallies within a week
• Avoid drawdowns — sustained outflows signal institutional de-risking, often aligned with multi-week corrections
• Spot rotation — BTC outflows alongside ETH inflows reveal sector rotation before it shows up in price
• Power your stack — pipe output into Google Sheets, Slack, Notion, or a custom alert bot with minimal code
• Monitor all issuers at once — BlackRock, Fidelity, ARK, Grayscale, VanEck, Invesco, and more aggregated into a single daily record per ETF type

Whether you are a quant trader, a crypto fund, or a DeFi protocol risk manager, this actor replaces hours of manual data collection with a single API call on Apify.

FAQ

Where does the data come from? All ETF flow data is sourced from SoSoValue, the same aggregator used by Bloomberg, CoinDesk, and major crypto media. It covers every SEC-approved US spot crypto ETF and updates roughly 1 hour after market close each trading day.

Does it cover Ethereum and Solana ETFs, not just Bitcoin? Yes. The actor tracks us-btc-spot (BlackRock IBIT, Fidelity FBTC, ARK ARKB, Grayscale GBTC, and others), us-eth-spot (BlackRock ETHA, Fidelity FETH, and others), and us-sol-spot (Solana spot ETFs). Enable or disable categories via the etfTypes input.

Can I get alerts when flows spike? Yes. Set alertInflowUsd or alertOutflowUsd together with a Telegram bot token and chat ID to receive real-time notifications when a single-day flow crosses your threshold — useful for catching panic sell-offs or major institutional accumulation events.
