Polymarket Traders Bet on Deeper Crash for Bitcoin and Ethereum in November

The period that traders once called crypto’s golden window has now become its worst nightmare.

Instead of the classic October–November rally, the market is being dragged deeper into a downturn with every passing week. Bitcoin’s slide to $81,000 has sent a shockwave through the entire sector, and the reaction from investors is unlike anything seen in recent cycles.

Rather than trying to buy the dip, most market participants now believe the decline will stretch into the short term — and prediction markets confirm that sentiment beyond any doubt.

Polymarket, a platform that people use to speculate on real-world outcomes, has completely flipped to the bearish side. The shift is so extreme that bullish expectations have practically disappeared, especially for Bitcoin and Ethereum, which together dictate the rhythm of the entire crypto space.

Bitcoin sentiment: confidence is gone

Not long ago, ambitious forecasts pinned Bitcoin above $200,000 before year-end. Today, speculation has taken a very different turn. The scenario that traders are betting on most heavily is BTC dropping beneath $80,000 during November, which has now become the dominant bet on Polymarket.

A deeper fall toward $75,000 is the second most-backed outcome, and optimism for any major rally is nearly nonexistent — the likelihood of Bitcoin trading above $115,000 is being priced at barely 2%. It’s not just fear; it’s a market that has stopped believing in a meaningful short-term recovery.

Ethereum forecasts fall even faster

If Bitcoin’s outlook is grim, Ethereum’s is worse. The majority of Polymarket speculators expect ETH to continue bleeding rather than stabilizing.

The leading prediction prices ETH below $2,600 with a 68% likelihood. The next most-backed outcome pushes the decline further, with a 33% chance of slipping below $2,400. Even a flash crash scenario — below $2,200 — is actively priced at 17%.

Meanwhile, the idea of Ethereum making a dramatic comeback has essentially evaporated. Only 2% of the market sees ETH surging above $4,000, showing that confidence in an explosive recovery has been nearly wiped out.

What this tells us about the market

Crypto isn’t just falling — expectations are collapsing with it. The psychological shift might be more important than the price action itself. For a market that has historically treated October and November as launchpads for major rallies, the current reversal symbolizes a turning point that few expected.

The biggest takeaway is not the percentage drops, but the collective belief that they are not finished. Polymarket’s pricing reflects a market preparing for continuation, not an imminent rebound. Until that mentality changes, speculative money will stay defensive — and long-awaited seasonal optimism won’t return.
