Institutional investors are continuing to pile into Bitcoin (BTC) despite prices pushing up to a five-month high.

According to CoinShares’ Tuesday “Digital Asset Fund Flows Weekly” report, more than $226 million in capital flowed to institutional Bitcoin products this past week. Bitcoin products dominated inflows for the third consecutive week, posting a week-over-week increase of 227%.

The heavy inflows coincided with the price of BTC gaining 12.5% for the week, with BTC sitting at around $54,000 on Friday.

CoinShares attributes the positive shift in sentiment toward Bitcoin to recent statements from United States Securities and Exchange Commission Chairman Gary Gensler suggesting the long-awaited approval of the U.S.’ first Bitcoin exchange-traded fund (ETF) may be just around the corner.

The surging activity surrounding Bitcoin has seen the combined assets under management (AUM) of institutional crypto products push up to $66.7 billion last week — with CoinShares estimating the total is just 5% shy of the sector’s record AUM from May.

Products tracking altcoins have posted mixed performances for the week, with Solana (SOL) and Cardano (ADA) products generating inflows of $12.5 million and $3 million, respectively. However, funds offering exposure to Ether (ETH), Polkadot’s DOT and XRP suffered outflows of $13.6 million, $2.1 million and $600,000, respectively.

Crypto investment products have now posted inflows for eight weeks in a row.

Many onlookers are attributing BTC’s recent bullish momentum to expectations that the SEC will soon approve a futures-based Bitcoin ETF.

While the SEC has previously shot down every application it has received for physically backed Bitcoin ETFs, the SEC is currently deliberating four applications for exchange-traded funds based on the Chicago Mercantile Exchange’s (CME) regulated futures contracts.

With CME’s futures markets offering a product that is already insured and overseen by U.S. regulators, pundits such as senior ETF analyst for Bloomberg Eric Balchunas believe that Bitcoin futures ETFs are “likely on schedule” to receive a regulatory green light this month.
