September and the BTC: what prediction markets are betting on?**
Now that September has started, the question dominating the crypto radar is whether the weakest month in Bitcoin’s history will repeat. And the most objective data to answer it doesn’t come from analysts’ opinions, but from prediction markets, where traders commit real capital.
On Kalshi, the regulated platform, traders are pricing roughly a 53% chance of BTC touching US$ 72.500 at some point during September. The probability of falling below US$ 75.000 is much higher, at around 80%. On Polymarket, the scenario “below US$ 75.000” leads with 77.5%. And aggregators like AimPredict have even reported 72% for a touch at US$ 72.000.
So there isn’t a single number. The range runs from 53% to 80%, depending on the platform and the exact level. But the direction is clear: most traders see a high likelihood that BTC won’t hold the current range, and what the month delivers will be a make-or-break test for August’s recovery.
Pessimism has also grown in the last few days. Demand turned negative, ETF outflows are weighing, and geopolitical tensions—like the U.S.-Iran risk—have reinforced the risk-off tone. Add to that the historical backdrop: September is, by far, the weakest month for BTC.
Worth adding some context: prediction markets measure the “probability of touching a price at some point during the month,” not the probability of closing the month lower. That tends to inflate the figures. And there’s also a technical counterpoint, with indicators still showing a slightly bullish bias in the short term.
Majority sentiment, but not unanimous. And, as always in crypto, volatility is the only certainty.
