Bitcoin is preparing to sign its best third quarter since 2017, with a gain of more than 42% since the beginning of July. The return of the price below $83,000, however, weakens this performance before the publication of decisive American data.
In brief
- Bitcoin gains more than 42% in the third quarter of 2026, its best performance since 2017.
- The $82,500 threshold becomes a key support after BTC’s recent decline.
- US data on inflation and employment could significantly revive volatility.
- A break below $82,500 would weaken the bullish structure observed in recent months.
Bitcoin maintains over 40% gains in third quarter
Bitcoin ended the week at $84,450, its highest weekly closing level since late January. Then, the price fell to 82,557 dollars, against a backdrop of tensions between the United States and Iran and liquidity movements on exchange platforms.
BTC is moving around $83,800 on September 29, after reaching $84,239 the previous day. It thus remains below its annual opening price, set around $88,700, less than two days before the quarterly close.
Multiple levels summarize now the balance of power:
- $88,700 is the 2026 opening price;
- $86,000 is the estimated average cost of US Bitcoin ETF buyers;
- $82,500 constitutes immediate technical support;
- $80,500 corresponds to the average price of corporate treasuries;
- 76700 dollars marks the average cost of active investors.
Buyers who entered the market over the last four weeks remain generally profitable. Their average acquisition price is nearly $78,300, according to CryptoQuant data.
The third quarter of 2026 becomes the best in nine years
Bitcoin shows quarterly growth of around 42.6%. We have to go back to the third quarter of 2017, marked by a gain close to 79.6%, to find superior performance over this period of the year.
The current increase represents almost five times the average performance of third quarters since 2013, estimated at 8.6%. It also contrasts with several difficult years. Bitcoin notably lost 10.8% in the third quarter of 2019 and 14.7% in 2014.
However, this performance does not guarantee an automatic continuation of the increase. The fourth quarter has historically produced an average return close to 77%, but this average remains strongly influenced by the exceptional surges of the first cycles, notably in 2013 and 2017.
The September 30 close will determine BTC’s final outcome in the third quarter of 2026. A rapid decline could further reduce the quarterly gain, although a complete reversal seems unlikely given the advance accumulated since July.
US inflation and employment can reignite volatility
The Bureau of Economic Analysis will release the Personal Consumption Expenditure Index for August on September 30. The market foresees an increase of 3.6% over one year and 0.3% over one month. In July, PCE inflation reached 3.7% year-on-year.
Inflation above expectations would reinforce expectations of monetary tightening. On September 28, contracts tracked by CME FedWatch assigned a 70.3% probability to another 0.25 point rate hike from the Federal Reserve in October, up from 57.7% a week earlier.
The September US jobs report will follow on October 2. The official Bureau of Labor Statistics calendar confirmed that economists expect around 83,000 job creations, after the 162,000 positions added in August.
A stronger-than-expected labor market could support bets on further rate hikes. This scenario would potentially weigh on bitcoin and other assets sensitive to liquidity conditions.
The support of 82,500 dollars becomes decisive
Analyst Rekt Capital compares the current structure of bitcoin to its exit from the bear market of 2022. The price then built a long accumulation zone around $30,000 in 2023.
“In this cycle, the level of around $82,500 corresponds to the top of the 2022 accumulation zone,” he explains. Maintaining above this threshold would allow bitcoin to form a new consolidation phase before a possible recovery.
A lasting break below $82,500 would weaken this historical comparison. According to the analyst, BTC could then return to its previous range of between $60,000 and $80,000. This projection remains a graphical scenario, and not a certain forecast.
