Morgan Stanley Buys $3.8M in Bitcoin Amid ETF Outflows -

Morgan Stanley Bitcoin buying reached $62.2M as MSBT extended its buying streak to four days again.
MSBT bought $3.8M in Bitcoin on Friday, while BlackRock’s IBIT saw $19.2M in net outflows then.
US spot Bitcoin ETFs recorded $462.7M in weekly outflows, while September flows stayed positive too.

Morgan Stanley continued accumulating Bitcoin as broader U.S. spot Bitcoin ETF flows turned negative, highlighting a divergence between the investment bank’s buying activity and recent withdrawals from major exchange-traded funds.

According to an X post published Monday by blockchain intelligence platform Arkham, Morgan Stanley’s crypto vehicle, MSBT, purchased $3.8 million worth of Bitcoin on Friday. The transaction marked the fund’s fourth consecutive day of positive inflows.

Arkham’s on-chain data showed that MSBT accumulated $62.2 million across 11 buying days during the past 20 trading sessions. The fund recorded no sell-off days during that period, according to the data cited in the post.

Morgan Stanley’s holdings have grown to approximately 7,855 BTC, with the assets valued at about $610 million, Arkham’s dashboard showed. The figures provide a snapshot of the fund’s continued accumulation despite fluctuations in broader market flows.

Morgan Stanley Continues Bitcoin Accumulation

The latest purchase added another $3.8 million in Bitcoin to MSBT’s holdings. It also extended the vehicle’s buying streak to four consecutive days.

Across the previous 20 trading sessions, MSBT accumulated $62.2 million over 11 buying days. Arkham’s data showed no days of selling during that period.

The accumulation has brought Morgan Stanley’s reported holdings to roughly 7,855 BTC. At the valuation cited by Arkham, those holdings are worth approximately $610 million.

The activity stands in contrast to flows recorded by some major U.S. spot Bitcoin exchange-traded funds. On the same day Morgan Stanley added $3.8 million in Bitcoin, BlackRock’s iShares Bitcoin Trust ETF, known as IBIT, recorded $19.2 million in net outflows.

The different flows show that institutional Bitcoin activity was not moving uniformly during the period covered by the data. Morgan Stanley’s crypto vehicle continued to record purchases, while at least one major spot Bitcoin ETF experienced withdrawals.

Spot Bitcoin ETFs Record $462.7M in Outflows

The Morgan Stanley purchases came as U.S. spot Bitcoin ETFs recorded $462.7 million in net outflows over four trading sessions from Tuesday through Friday.

The withdrawals followed three consecutive weeks of inflows. The reversal came after what had been the strongest three-week inflow run of 2026, according to the supplied data.

The funds recorded $166.8 million in combined outflows during the first two days of the holiday-shortened week. Selling then increased on Thursday, when U.S. spot Bitcoin ETFs recorded $282.7 million in net outflows.

Friday’s outflows slowed to $13.2 million, but the withdrawal extended the negative streak to four consecutive trading sessions.

ARK 21Shares Bitcoin ETF recorded the largest weekly outflow at $234.2 million. Grayscale’s Bitcoin Trust ETF followed with $129.1 million in net outflows.

BlackRock’s IBIT recorded $52.5 million in net outflows during the week, while Fidelity’s Wise Origin Bitcoin Fund posted $50.7 million in withdrawals.

Despite the weekly reversal, U.S. spot Bitcoin ETFs remained in positive territory for September, with approximately $307.3 million in net inflows through Friday.

Morgan Stanley Buying Contrasts With ETF Flows

Morgan Stanley’s continued accumulation occurred against a backdrop of mixed institutional Bitcoin flows. The investment bank’s MSBT vehicle purchased Bitcoin for four consecutive days, while major spot ETFs experienced substantial withdrawals during the same period.

The contrast was particularly visible on Friday. MSBT purchased $3.8 million worth of Bitcoin, while BlackRock’s IBIT recorded $19.2 million in net outflows.

Arkham’s data also showed that MSBT accumulated $62.2 million across 11 buying days in the previous 20 trading sessions without recording a sell-off day.

At the same time, U.S. spot Bitcoin ETFs collectively recorded $462.7 million in net outflows over the four-session period. The figures show differing flows across institutional Bitcoin investment vehicles.
