What is the Glimpse Bitcoin price forecast?
The Glimpse Bitcoin price forecast works like a weather forecast for Bitcoin. A weather forecast gives the chance of rain on a given day. The Glimpse forecast tells you the chance that Bitcoin ends up at each price.
The forecast comes from real people putting real money on the line. Glimpse is a prediction market where anyone can bet bitcoin on where the price of Bitcoin will be at a set time.
Glimpse builds the forecast in five steps.
- Glimpse splits the possible prices into small slices. Each slice is a narrow band, such as $84,400 to $84,600.
- People buy the slices they believe in. Each slice pays out in bitcoin if Bitcoin's price ends the hour inside it.
- Popular slices get more expensive. The more people expect a slice to win, the more it costs. That cost shows the crowd's odds for that slice.
- The slices add up to one forecast. Glimpse combines every slice into a single expected price for each hour.
- The real price settles every bet. When the hour ends, people who picked the right slice get paid. People who picked wrong lose what they put in.
Wrong guesses cost money and right guesses earn it. That gives everyone a reason to bet on what they truly believe. The result is one forecast built from the honest best guess of every trader.

How does Glimpse predict the Bitcoin price?
Glimpse runs a prediction market for every hour. People bet bitcoin on which price slice Bitcoin will end the hour in. The prices of those slices show the crowd's odds, and Glimpse combines them into one Bitcoin price forecast.
The math behind the Glimpse Bitcoin prediction market
The Glimpse Bitcoin price forecast runs on a pricing engine called the liquidity-sensitive logarithmic market scoring rule, or LS-LMSR. This section explains what that means, how Glimpse applies it to Bitcoin, and why it produces a reliable Bitcoin price prediction over time.
What is a Bitcoin prediction market?
A Bitcoin prediction market lets people trade on the future price of Bitcoin. Each contract pays out only if a stated outcome happens. The price of a contract reflects how likely traders think that outcome is. Read together, the prices of all contracts form a forecast.
Most prediction markets, including Polymarket and Kalshi, ask yes-or-no questions such as "Will Bitcoin close above $85,000?" A single yes-or-no answer holds one piece of information. A Bitcoin price forecast needs the full picture of every price Bitcoin might reach and how likely each one is.
What is the logarithmic market scoring rule (LMSR)?
The logarithmic market scoring rule, or LMSR, is a method for running a prediction market without an order book. An automated market maker quotes a price for every outcome at all times. Traders buy from it and sell to it directly, so there is always someone on the other side of a trade.
The LMSR grew out of scoring rules used to grade weather forecasters. A scoring rule pays forecasters according to how much probability they gave to the outcome that actually happened. The logarithmic score has a special property. A forecaster earns the most, on average, by reporting exactly what they believe.
The LMSR turns that scoring rule into a shared market. Each trader moves the market's forecast toward their own view. If the move makes the forecast more accurate, the trader profits. If the move makes it less accurate, the trader loses. Trading profit equals the improvement a trader adds to the forecast.
The LMSR keeps every price positive, and the prices across all outcomes behave like a probability distribution. The operator's worst possible loss is fixed in advance, so the market can stay open and liquid from the very first trade.
What is the LS-LMSR?
The standard LMSR uses a fixed liquidity setting. That setting decides how much money it takes to move prices. A fixed setting is either too sensitive when a market is busy or too sluggish when it is quiet.
The liquidity-sensitive logarithmic market scoring rule, or LS-LMSR, solves this. Its liquidity grows with the amount of money traded in the market. A small bet moves the price a lot in a quiet market. The same bet moves the price only slightly in a busy one. A busier market therefore produces a steadier and more trustworthy forecast.
The LS-LMSR keeps the core strengths of the LMSR. Prices depend only on the total amount bought of each outcome, regardless of the order of trades. This property is called path independence. It means a trader cannot game the market by splitting, timing, or reordering orders.
How Glimpse applies the LS-LMSR to Bitcoin
Glimpse applies the LS-LMSR to the closing price of Bitcoin at a set hour. Glimpse calls this design the quantile LS-LMSR. It splits the full Bitcoin price scale into hundreds of narrow price bands. One automated market maker prices every band at once through a single formula.
Each band is a contract that pays 100 sats ($0.08 USD) if Bitcoin closes inside it. Buying a band raises its price and lowers the prices of the others. The prices across all bands form a complete probability curve for the Bitcoin price at that hour. Glimpse summarizes that curve as one expected price, which is the Bitcoin price prediction shown in this article.
Glimpse runs a separate market for every hour. All markets trade, settle and pay out in bitcoin. Deposits and withdrawals work over Lightning or on-chain.
Each market opens with a small subsidy from Glimpse spread evenly across all bands. That subsidy gives the first traders good odds and rewards them for adding information early. The most Glimpse can lose on any market is set before it opens.
Why the LS-LMSR makes Bitcoin price forecasting reliable over time
The LS-LMSR rewards honesty. In a market where traders hold independent information, betting on what you truly believe is the best strategy. Bluffing or holding back information cannot earn a profit. Bitcoin suits this well, because it trades around the clock with no earnings reports or insider disclosure windows. Traders form their views from independent data and independent methods.
Order book markets work differently. An order book is zero-sum, so every winner needs a loser on the other side. In thin markets, informed traders have a reason to hide what they know. Prices on an order book can also be pushed around on purpose, because misleading other traders can pay.
The LS-LMSR also gets sharper as it grows. More traders bring more independent views. More volume deepens liquidity, so each forecast becomes harder to move without real information. The forecast improves with every trade.
The track record reflects this. In the week from October 14 to October 21, 2026, the Glimpse Bitcoin price forecast picked the correct price range in 154 of 168 hours, for 92% accuracy. Across 1,440 hourly Bitcoin markets over a 60-day period ending in October 2026, it had 85% accuracy. Glimpse produced these results with a small community of traders. Each new trader adds information and makes the Bitcoin price forecast more accurate.
