The Week in Bitcoin - September 21–27, 2026
Bitcoin closed the week at $84,221: 30% below our $120,000 base case and 20% above our $70,000 bear case, with 13 weeks left in the year. The gap to the base case narrowed from 32% a week ago.
Reaching our base case by December 31 would take a 42% rally from here.
Top story of the week
Bitcoin ETFs took in $2.4 billion and turned positive for 2026.
It was the funds' largest weekly inflow since October, and it pulled year-to-date net flows back above zero after they sat about $5.8 billion in the red two months ago. The buying arrived in a hostile rate backdrop: the 10-year Treasury yield hit a 19-year high the same week.
Other headlines this week
Strategy wants to pay preferred dividends every day. It asked shareholders to approve daily accrual on STRF, STRC, STRK and STRD at an October 28 meeting, an attempt to lift STRC, which has traded below $100 since May despite a 12% dividend.
Washington keeps moving without Congress. The CFTC is re-examining rules for 24/7 on-chain markets now that the Clarity Act has stalled, while SEC Commissioner Hester Peirce, the agency’s most consistent crypto advocate, leaves on October 2.
Another European bank opens the door. Raiffeisen plans to roll out Bitcoin trading with Bitpanda across its network; launch dates and markets aren’t set yet.
What it means
The ETF number is the headline, but the more telling signal is when the buyers came back: in a week of 19-year-high Treasury yields, an oil market on edge over the Strait of Hormuz, and a Fed that hiked the week before. Bitcoin didn’t need easy money to find demand.
In Washington, the momentum has moved from Congress to the agencies, just as the SEC loses its most consistent advocate for the industry. The next steps on market structure will come through rulemaking, not legislation.
Market Brief
As of Sunday, September 27, Bitcoin stood at $84,221, with a market capitalization of $1.69 trillion and 1,187 sats per dollar.
Bitcoin opened Monday at $81,244 and closed Sunday at $84,221, a 3.66% gain.
Monday did most of the work: a close at $86,200 and a high of $87,029, its highest level since late January. From Wednesday on, closes settled into a narrow $84,100–$84,300 band.
Our market view
On September 18, Bitcoin closed above its 1-year average ($79,947) for the first time since November 2025, roughly what the past year's buyers paid. With most of them back in profit, there's less selling pressure overhead. This week's quiet finish after Monday's jump looks like digestion, not rejection.
Holding $80,000: we expect a range up to this week’s $87,000 high, with a retest of the high more likely while ETF demand holds.
Below $80,000: the next floor is $70,000–73,800, where recent buyers’ average cost ($72,880), the 200-day average ($71,036) and our bear case meet.
Above $87,000: little resistance until $100,000.
These are levels to watch, not predictions.
Seasonal Context
September is up 7.23% with three days left, against a historical median of −4.76% by this date. If it holds, it would be the third-best September since 2012, behind only 2012 and 2024.
The heatmap shows the turn: after June’s 21% drop, July, August and September have all finished higher, the year’s longest monthly winning streak. October is next, historically Bitcoin’s strongest month: up in 10 of 14 years, with a median gain of 13.4%.
Year to date, Bitcoin is down 3.52%, an improvement from −6.93% a week ago, but still well behind the historical median gain of 44.07% by this date.
Looking Ahead
This week: US employment and inflation data, with markets weighing the odds of another Fed hike.
October 2: Hester Peirce’s last day at the SEC.
October 28: Strategy’s shareholder vote on daily preferred dividends.
