Crypto ETF Flow Tracker — BTC, ETH and SOL Flows

Track daily US crypto ETF inflows and outflows for analysts monitoring BTC, ETH, and SOL funds.

Quick start

Run this small input (observed under two minutes):

{"etfTypes":["us-btc-spot"],"daysBack":1,"includeIndividualEtfs":false}

One real flow item from the 2026-10-05 run (selected fields; a market-summary item also follows):

{"etf_type":"us-btc-spot","etf_subtype":"spot","date":"2026-10-02","net_inflow_usd":189844086.2,"value_traded_usd":3025876699.6,"total_net_assets_usd":108893049844.69,"cum_net_inflow_usd":57787814959.12,"is_inflow":true,"flow_momentum":"strong_inflow"}

etf_type identifies the fund group and date the trading day. net_inflow_usd is signed daily flow; cum_net_inflow_usd is cumulative flow. total_net_assets_usd is assets under management, value_traded_usd is volume, and is_inflow/flow_momentum summarize direction. Values change with the source.

Limits

Supported groups are us-btc-spot, us-eth-spot, and us-sol-spot; the SOL group is futures-backed, not a US spot SOL ETF. SoSoValue may return fewer days or fail; without live data or a prior cache, daily rows are absent. Alerts require your own Telegram credentials or webhook.

Pricing

Active Apify contract verified 2026-10-05:

Event	Price

More about Crypto ETF Flow Tracker

Crypto ETF Flow Tracker fetches daily net inflow and outflow data for US-listed Bitcoin and Ethereum spot ETFs and the supported SOL futures-backed group from SoSoValue. No API key is required; source availability and run time vary.

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.

How to Use Crypto ETF Flow Tracker

1. Open the actor on Apify Store and click Try for free
2. Set your inputs — choose ETF types (us-btc-spot, us-eth-spot, us-sol-spot), lookback window (1–300 days), and optional Telegram alert thresholds
3. Click Start — the actor fetches live data from SoSoValue and returns structured records
4. Access results in the Apify dataset viewer, download as JSON or CSV, or hit the dataset API endpoint from your code
5. Schedule it — set a daily cron (0 13 * * 1-5) in Apify Schedules to run every US market morning automatically

No account registration, no third-party API keys, no proxy setup needed.

Input

Field	Type	Default	Description

sortBy	string	date_desc	Sort order: date_desc, date_asc, or abs_inflow_desc
alertOutflowUsd	integer	0	Send alert when daily net outflow exceeds this amount. 0 = disabled
alertInflowUsd	integer	0	Send alert when daily net inflow exceeds this amount. 0 = disabled
telegramBotToken	string (secret)	—	Telegram bot token for flow spike alerts
telegramChatId	string	—	Telegram chat ID to receive alerts

{
  "etfTypes": ["us-btc-spot", "us-eth-spot", "us-sol-spot"],
  "lookbackDays": 7,
  "sortBy": "date_desc"

Outflow panic alert — BTC ETFs losing >$1B in a single day:

  "etfTypes": ["us-btc-spot"],
  "lookbackDays": 1,
  "alertOutflowUsd": 1000000000,
  "telegramBotToken": "<your-bot-token>",
  "telegramChatId": "<your-chat-id>"

Output

Each record represents one day's aggregated flow for a single ETF category. A 30-day run across all three ETF types returns 90 records.

Data sourced from SoSoValue — the industry-standard public ETF flow aggregator. Updates approximately 1 hour after US market close. Up to ~300 days of historical daily data available per ETF type. Cache fallback: if SoSoValue is temporarily unavailable, the actor serves the last successful dataset and flags data_source in the run summary.

Cost Estimation

See the active-contract Pricing section above. Total cost includes the start event plus any flow rows after the 14-row exemption; the number of available rows varies.

FAQ

Where does the data come from? ETF flow data is sourced from SoSoValue. Coverage and update timing depend on the public source; the supported SOL group is futures-backed.

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 (futures-backed SOL products). Choose groups with etfTypes.

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.

Works Great With

Build a complete institutional signal stack with these actors from the same author:

• Hyperliquid Whale Tracker — Spot institutional moves on-chain alongside ETF flows. When ETF inflows spike, check if the same whales are accumulating on Hyperliquid perps — confirming the conviction behind the flows.
• CEX Reserve Tracker — Track exchange reserves to confirm institutional accumulation. Rising ETF inflows combined with falling CEX reserves (coins moving to cold storage) is one of the strongest bullish convergences in the market.
• Bitcoin Mempool Analytics — Layer on-chain signals with ETF demand data. High mempool fees alongside strong ETF inflows signal genuine demand — not just paper trading. Low mempool activity during "inflow days" can indicate ETF flows aren't translating to chain activity.
• Economic Calendar Tracker — ETF flows often spike or crater on macro prints. Combine CPI, FOMC, and NFP event data with daily ETF flows to build a macro-driven institutional flow model.
