Bitcoin Weekly Outlook: BTC, ETF Flows and US Data

Review: September 21–25, 2026, with a September 26 update | Outlook: September 28–October 2, 2026

The Bitcoin weekly outlook starts with BTC holding around $84,100 during Saturday morning UTC checks, after an early-week rally lost momentum. Strong US spot Bitcoin ETF inflows supported the demand picture, but the market also absorbed a major options expiry and an exchange security incident.

The coming week combines the September quarter-end with US inflation and employment releases. The central question is whether fresh buying can rebuild momentum after the retreat from this week’s highs.

Bitcoin trades continuously. The completed business-week review below is separate from Saturday’s changing price and from the still-unfinished Sunday weekly candle.

Bitcoin price review: a strong start, followed by a pullback

CoinGecko’s UTC daily history provides the closing-price basis for this comparison.

Monday’s gain was approximately 6.69%, calculated from the same series. Subsequent selling reduced that advance without erasing the completed business week’s gain.

This is a five-day review measured from the preceding Sunday close, not a finalized seven-day crypto-week return. All percentage calculations use one provider’s closes; exchange prices and data-provider aggregation can differ.

The price pattern creates a practical distinction. Bitcoin remained higher than its starting reference, but buyers entering after Monday’s surge experienced a different market. Continued recovery now needs evidence of renewed demand rather than an assumption that the initial rally will automatically resume.

Spot Bitcoin ETF flows: positive, but slowing through the week

Farside Investors’ table showed the following US spot Bitcoin ETF net flows when checked on September 26:

The completed business-week total was therefore approximately $2.386 billion, calculated by summing these five rows.

Friday’s table matters: Bitwise’s $11.8 million outflow was outweighed by inflows elsewhere. An individual fund’s negative number should not be described as the market-wide total.

The interpretation is constructive but qualified. Net flows remained positive while their daily size declined. Continued inflows could help absorb selling, but slower buying may offer less support if supply increases.

ETF flows describe one channel of demand; they do not identify every investor’s motive or capture all spot and derivatives activity. The table can be revised, and ETF reporting follows US business days while BTC continues trading over the weekend.

The options expiry has passed: what changes next?

CoinDesk reported before Friday’s settlement that roughly $15.9 billion of Bitcoin options were scheduled to expire on Deribit on September 25 at 08:00 UTC. Its estimate was attributed to Deribit’s CEO.

That expiry belongs in the review, not next week’s upcoming-event list. The notional figure describes the scale of contracts scheduled to mature; it is not $15.9 billion of compulsory spot Bitcoin selling.

Deribit’s settlement documentation explains that expiring contracts are ultimately cash-settled rather than requiring physical delivery of the underlying asset. Hedging adjustments around expiry can nevertheless affect trading.

For the new week, the useful question is how fresh positioning develops after those contracts disappear. Buyers may establish new exposure, sellers may rebuild hedges, or both sides may reduce activity.

Expiry alone does not establish the direction of the next move. A durable price recovery accompanied by fresh demand would carry more information than the expiration headline itself.

Corporate Bitcoin demand was not a one-way story

Strategy’s September 21 SEC filing disclosed the purchase of 950 BTC for approximately $75.7 million, taking holdings to 846,000 BTC as of September 20.

The buying occurred during September 14–20. It was announced this week; it should not be counted as a verified purchase made during September 21–25. The filing said the acquisition used the company’s USD Cash.

A contrasting announcement came from Sequans on September 24. The semiconductor company said it had completed its Bitcoin treasury exit by selling the remaining 314 BTC held at June 30.

These are company-specific capital-allocation decisions. Together they show why corporate headlines should be read individually rather than treated as proof that every treasury is accumulating. Neither announcement, by itself, establishes the timing or size of next week’s market orders.

Bitget security incident: distinguish the plan from restored service

Bitget disclosed unauthorized transfers detected on September 24 and temporarily suspended withdrawals. Its September 25 official update revised the amount transferred to attacker-controlled addresses to approximately $387.5 million, from an initial $351.6 million.

The exchange said the revision reflected more complete transaction tracing rather than additional unauthorized transfers. It also said the vulnerability had been remediated and that Mandiant and SlowMist were assisting its investigation. These are the company’s statements.

On September 26, BlockBeats reported Bitget’s phased withdrawal plan, with Bitcoin-network BTC withdrawals scheduled for September 28 at 08:00 UTC.

A schedule is not confirmation that restoration has happened. Actual availability needs to be checked against the exchange’s subsequent status updates.

For the broader BTC outlook, this is an operational-confidence issue as well as a headline risk. Exchange access, custody arrangements and market liquidity are separate considerations from a bullish or bearish price view.

Why PCE inflation and payrolls matter for Bitcoin

US macroeconomic releases can influence the dollar, Treasury yields and investors’ appetite for risk. For Bitcoin, the reaction depends on how the data changes expectations—not simply whether the headline number is positive or negative.

Softer inflation without a sharp growth deterioration could ease pressure from interest-rate expectations and provide a more supportive environment for risk assets.

Persistent inflation with resilient employment could keep yields elevated and challenge valuations across speculative assets, including crypto.

A severe labour-market disappointment could produce an initial risk-off reaction even if it later increases expectations of easier policy. Weak data is therefore not automatically bullish for Bitcoin.

These are transmission scenarios, not a forecast of next week’s releases. The sequence matters: Wednesday’s inflation data arrives before Friday’s employment report, so the first interpretation may be revised by the second.

September 30 also marks quarter-end. Portfolio adjustments may add volatility, but there is no verified basis here for assuming they must produce net Bitcoin buying or selling.

BTC technical reference zones

The following intraday observations come from Investing.com’s historical BTC/USD series. They are rounded into zones for analysis and are separate from the CoinGecko closing-price series used above.

These zones describe where recent trading occurred. They are not guaranteed support, resistance or execution prices.

A recovery through the nearer resistance zone would suggest that buyers are reclaiming ground lost late in the week. A move toward the upper zone would then test whether the market can revisit its recent peaks without immediately attracting renewed selling.

A sustained loss of the first support zone would make the earlier breakout area more relevant. Confirmation should come from how price behaves after the break, rather than from one isolated wick.

Bitcoin calendar: September 28–October 2

All times are UTC. Add 5 hours 30 minutes for India Standard Time.

Dates and times were checked against agency schedules, the economic calendar and the dated withdrawal-plan report.

Agency schedules can change. ETF totals also arrive progressively; early partial reports should not be confused with the completed daily aggregate.

The October 2 employment release falls at 18:00 IST, while the September 30 PCE release is also scheduled for 18:00 IST. Bitcoin can react immediately, including while traditional markets are preparing to open.

Three scenarios for the week ahead

Bullish continuation: BTC holds the lower support area, regains approximately $85,250 and sustains the recovery. Continued fund inflows and a supportive macro reaction would strengthen the case for retesting the recent highs. Rejection back below the recovered zone would weaken that interpretation.

Consolidation: Price oscillates between the nearby support and resistance zones while participants wait for the next demand and macro signals. A quiet period after expiry would not, on its own, prove either accumulation or distribution.

Deeper correction: BTC remains below resistance and loses approximately $82,950 on sustained trading. That would put the earlier $81,000 area back into focus. A rapid recovery above the broken zone would undermine the bearish reading.

These scenarios are conditional. Weekend moves can change the starting position before Monday, and leveraged markets may amplify reversals in either direction.

What would make the next move more convincing?

Three observations deserve attention together: whether price holds a reclaimed level, whether new fund-flow reports remain supportive, and whether yields and the dollar reinforce or oppose the move.

Agreement between those observations would provide a stronger case than any single headline. Disagreement would call for caution about extrapolating the initial reaction.

For example, positive ETF flows alongside a falling price can indicate that selling elsewhere is outweighing that demand. A rising price with weaker flows can reflect other buyers or changes in derivatives positioning. Neither relationship should be reduced to a mechanical rule.

For continuity, revisit our previous Bitcoin weekly forecast, then compare the new evidence with the levels and scenarios in this update.
