The Options Market Prices a Near-Term Bitcoin Dip at Nearly 40 Percent. The Betting Crowd Puts It at 13.

By Kresmion Research, July 31, 2026

Two separate markets are pricing the same question, and they do not agree. The question is whether Bitcoin, trading near $63,700 on Friday, dips to $62,500 by the close on Saturday, August 1. On Polymarket, where people bet directly on the outcome, the price implies about a 13 percent chance. On the Deribit options chain, the same touch works out to about 38 percent. One venue thinks a small dip is unlikely. The other treats it closer to a coin flip on one side.

The gap is not a glitch, and it is not the options market bracing for a fall. It is one of the cleaner live examples of a well-known feature of options pricing. This piece works through what the two numbers are, why they differ, and the honest reasons the wider gap does not mean what it first looks like.

The two numbers

Kresmion computes, for each Polymarket price-threshold market, the probability of that same event implied by the Deribit options chain, using the listed option volatilities. For the market asking whether Bitcoin reaches $62,500 by the August 1 close, Polymarket prices about 13 percent and the options chain implies about 38 percent. The move in question is small: from about $63,700 to $62,500 is a drop of under two percent. So the disagreement is not about a crash. It is about whether even a modest pullback happens in the next couple of sessions.

It is not one contract

If this were a single odd quote, it would not be worth much. It is not. Across every near-term crypto price market where the two venues diverge enough to compare, the options chain sits higher than the betting crowd, and it sits higher on the same side every time. The market on Bitcoin reaching $62,000 by August 2 is about 23 percent on Polymarket against about 36 percent implied by options. The market on Ethereum, trading near $1,880, dipping to $1,800 by the weekend is about 4 percent on Polymarket against about 21 percent implied by options. Even the longer-dated Ethereum markets show it: a dip to $1,500 by year end is about 43 percent on Polymarket against about 59 percent implied by options. Six markets clear the comparison threshold today, and all six point the same way. The options chain consistently prices a larger chance of a fall than the crowd does. A separate question is what a betting price looks like when nobody has a paying reason to correct it, which is what we found on Polymarket's year end Bitcoin ladder on August 5.

Why the options number is higher

The two numbers are measuring slightly different things, and that difference is the point. The options figure is a risk-neutral probability. It is the chance of the move backed out from the price of options, and the price of options includes the premium that sellers charge for carrying risk. Because sellers demand that premium, option-implied volatility tends to sit above the volatility that actually arrives. By one widely cited estimate, implied volatility on major index options exceeds the volatility that later shows up in something like 85 percent of periods. That gap has a name, the volatility risk premium, and it means a probability read off the options chain is not a forecast of what will happen. It is the odds priced into insurance, premium included.

The betting market is a more direct estimate of what participants think will actually occur. So when Polymarket says 13 percent and the options chain says 38 percent, a large part of the difference is not a disagreement about Bitcoin at all. It is the premium baked into the price of options, showing up as a higher implied probability. The premium is not the whole story. Betting markets carry their own frictions, including thin liquidity in these specific contracts, the cost of locking up capital until they settle, and a known tendency for longshot outcomes to trade cheap, and those explain part of the residual too. What points past a simple disagreement is the shape of the gap: it runs one way, and it is present on every contract, which is the fingerprint of a pricing feature rather than a view on where Bitcoin goes. Kresmion publishes both figures side by side precisely so the gap is visible rather than hidden inside one venue.

The tape that disagrees

The tempting read is that the options market is quietly hedging a fall. The tape says otherwise, and this is the counter-evidence the story needs. Friday is a large month-end options expiry, about $9.6 billion in Bitcoin contracts, and its max pain level sits right at $64,000, near the current price, a level that tends to pin rather than push. The put-to-call ratio into the expiry is about 0.28, which is a call-heavy book with limited demand for protection against a fall. Implied volatility has stayed low for weeks while Bitcoin held its range in the low-to-mid $60,000s. None of that describes a market loading up against a drop. It describes a calm, range-bound market whose options still carry the usual volatility premium. That premium, rather than fear, accounts for much of the gap.

Positioning fits the calm reading rather than a fearful one. On Binance, Bitcoin perpetual accounts are about 63 percent long and Ethereum about 71 percent long, with funding close to flat on both. Crowded long books with quiet funding are not the signature of a market paying up to hedge a fall.

What would change the read

The clean part of this is that it resolves quickly. The near-term markets settle at the August 1 close, so within a couple of sessions the disagreement is scored. If Bitcoin slips to $62,500, the options chain will have been closer, and the volatility it priced was warranted. If it holds near $64,000, as the low realized volatility and the max-pain pin suggest is the base case, the betting crowd will have been closer, and the gap was the premium all along. Either way the number to watch is simple: whether Bitcoin trades under $62,500 before the weekend is out. The two venues have staked out different answers, and the tape settles it.

Key takeaways

Frequently asked questions

Does the 38 percent options figure mean Bitcoin will probably not dip? No. It means the options-implied, risk-neutral chance of the touch is about 38 percent. That number includes the premium that option sellers charge, so it tends to overstate the real-world chance of the move. It is the odds priced into protection, not a forecast.

Why would a betting market and an options chain ever agree, then? They price related but different things. The betting market is a direct estimate of the probability people assign to an outcome. The options chain is a price for risk, and it carries a premium on top of the raw probability. The two can move together, but the options side usually reads higher for events that involve volatility, which is what this data shows.

Is this a sign that a Bitcoin drop is coming? No. This is descriptive market structure, not a forecast. The current tape is calm and range-bound, positioning is crowded long, and the options book is call-tilted rather than braced for a fall. The gap is mostly the volatility premium, which is present in quiet markets and stormy ones alike.

What is the volatility risk premium in one line? It is the tendency for the volatility implied by option prices to sit above the volatility that actually arrives, because sellers of options charge for taking on risk. This page is information, not investment advice.
