# Four more funds on the on-chain spot ETF flows

October 2026 · Web app · API

Spot Bitcoin ETF Onchain Flows, its USD view and the on-chain total now include the Grayscale Bitcoin Mini Trust, the Morgan Stanley Bitcoin Trust, BlackRock BITA and Osprey OBTC, each from its first reliable day. Methodology version 2026-10-14.

## What's new

The on-chain spot ETF flow charts now draw four more funds: the Grayscale Bitcoin Mini Trust (BTC), the Morgan Stanley Bitcoin Trust (MSBT), BlackRock BITA and Osprey OBTC. Spot Bitcoin ETF Onchain Flows and Spot Bitcoin ETF Onchain Flows USD show them as their own series, and the on-chain daily total, in bitcoin and in US dollars, now sums them as well.

Each fund starts on its first reliable day, so no early attribution ramp is counted as a flow. The Mini Trust starts on 13 Jun 2025, OBTC on 4 Jun 2025, MSBT on 8 Apr 2026 and BITA on 10 Jun 2026. A fund has no flow on its start day, and its first flow is the next day.

## Methodology

The totals restate from those days. History before each start day is unchanged.

The new series are available through the Newhedge API as `btc_etf_spot_flows_btc_onchain`, `msbt_etf_spot_flows_btc_onchain`, `bita_etf_spot_flows_btc_onchain` and `obtc_etf_spot_flows_btc_onchain`, with matching `_usd_onchain` series. The on-chain holdings by fund now carry the same four tickers, `BTC`, `MSBT`, `BITA` and `OBTC`. The data definitions carry methodology version 2026-10-14.
