Bitcoin Surges to Highest Level Since January as Spot ETFs Pull in Nearly $1 Billion in a Single Day

Bitcoin climbed as high as $87,363 on September 22, its strongest price since January 2026, before consolidating near $86,000. The advance pushed the total crypto market capitalization back above $3 trillion, with some measures placing it at $2.9 to $3 trillion depending on the source and timing. The Crypto Fear and Greed Index surged to 78, approaching but still below the August 26 peak of 82.

The rally's institutional backbone was a record-setting day for US spot Bitcoin ETFs, which attracted $998.9 million in a single session on Monday, the largest daily inflow of 2026 and the strongest since October 2025. BlackRock's IBIT led all funds with approximately $381 million in net inflows, followed by ARK Invest's ARKB at $289 million and Fidelity's FBTC at roughly $239 million. Separately, asset manager Strive disclosed a purchase of 1,355 Bitcoin, adding to the wave of institutional accumulation.

The price surge liquidated approximately $919 million to $1 billion in short positions, temporarily taking down Coinbase during peak trading volume. Crypto-adjacent equities including MicroStrategy, Coinbase and Circle slipped even as Bitcoin held above $86,000, a divergence traders noted as unusual. Ethereum recovered toward $2,800 with expanding open interest, and XRP reclaimed a key resistance level as altcoins broadly participated in the move.

Options markets reflected growing conviction that the rally has further to run. A $3.2 million Bitcoin butterfly options trade placed through institutional desks is structured to pay out if Bitcoin reaches $95,000 by the end of October, a setup that traders warned could trigger a gamma squeeze if spot prices continue rising. Analysts identified $90,000 as the next key technical level Bitcoin must clear to sustain momentum.

In an on-chain footnote to the rally, a long-dormant Bitcoin wallet moved 600 BTC worth approximately $51.3 million after 14 years of inactivity. The coins were originally worth around $4,800 when last transacted, underscoring the magnitude of Bitcoin's long-term appreciation. The Bitcoin Rainbow Chart, a valuation model, indicated that BTC remains in historically undervalued territory even at current prices heading into October.
