Prices are rising, but is this rally driven by people actually buying and holding, or by leveraged money pushing against itself? These two types of rallies have very different staying power. A spot-driven rally comes from buyers willing to take on price risk with their own capital. A leverage-driven rally comes from borrowed money, and borrowed money has a liquidation price. Once price hits that level, forced selling creates more forced selling.

To judge which type of rally you are looking at, you do not need to predict price direction. You only need to look at three core indicators in the derivatives market: Open Interest (OI), Funding Rate, and liquidation data. Together, they tell you who is pushing the price, and how fragile that push is.
The Difference Between Spot-Driven and Leverage-Driven Rallies
Spot buying means directly purchasing the asset. The buyer pays the full amount, receives the coins, and can withdraw them or leave them on the exchange. This trade does not involve borrowing, has no forced liquidation price, and the buyer can at most lose their entire principal. They will not be "forced out" by price swings.
Leveraged buying means opening a long position through derivatives contracts, mainly perpetual futures. The trader only puts up a portion of the position as margin and borrows the rest to amplify exposure. This position has a maintenance margin requirement. When losses eat into the margin to a certain level, the exchange's liquidation engine will force-close the position. The selling pressure from liquidation can push prices lower, potentially triggering more liquidations.
Both types of buying may look the same on a candlestick chart, but they leave different traces in derivatives data.
Core Indicator 1: How to Read Open Interest Together with Price
Open interest is the total value of all unsettled derivatives contracts in the market. It measures "how much leveraged money is staying in the game."
The combination of price and OI points to different market structures:
Price up + OI up: New leveraged money is entering. The trend may have momentum, but if OI rises too quickly, it means liquidation clusters are building up and the market becomes fragile. If price reverses, cascading liquidations can amplify the drop.
Price up + OI down: This is a typical sign of a spot-driven rally. Price is rising, but total derivatives positioning is falling. The decline usually comes from short covering, where shorts are forced to buy back, or from longs taking profit and leaving. No new leveraged longs are stepping in to absorb the move. The buying is coming from the spot market.
In a rally in August 2026, Bitcoin rose 24% from its low, while open interest fell from 762,000 BTC to 715,000 BTC, a two-month low, alongside roughly $3 billion in short liquidations. This combination of "price up, OI down" was interpreted by analysts as a signal that spot buying was absorbing short-covering demand.
Price down + OI up: New shorts are opening positions. The downtrend is being driven by leverage. If short positioning becomes overly crowded, a short squeeze could trigger a rebound.
Price down + OI down: Longs are leaving. Downward momentum may be fading.
Core Indicator 2: Funding Rate Tells You Which Side Is Paying
Perpetual futures have no expiry date. They use the funding rate to anchor the contract price to the spot price. When the perpetual contract price is higher than spot, the funding rate is positive, and longs pay shorts. When the contract price is lower than spot, the rate is negative, and shorts pay longs.
The absolute value of the funding rate reflects how crowded leveraged longs or shorts are. A persistently high positive rate means people going long are willing to keep paying to hold their positions. Market sentiment is strongly bullish, but it also means long positioning is crowded. If price pulls back, crowded longs may rush to exit at the same time.
On the other hand, a deeply negative funding rate means shorts are crowded, and the risk of a short squeeze is high.
What is truly informative is not whether the rate is positive or negative, but the combination of funding rate, price, and OI. If price is rising while the funding rate stays low or even neutral, it means the rally is not accompanied by extreme leveraged long demand. In that August 2026 spot-driven rally, the funding rate was around 10% annualized, far below the 50%–100% levels commonly seen at previous cycle tops.
If price rises, OI rises, and the funding rate also spikes, all three appearing at the same time means new leveraged longs are flooding in, and the market structure is becoming fragile.
Core Indicator 3: Liquidation Data Tells You Who Is Being Forced Out
Liquidation is the forced closure of a leveraged position. Every liquidation produces a market order in the opposite direction of that position. Long liquidations create selling. Short liquidations create buying.
When looking at liquidation data, pay attention to two things: size and direction.
Large-scale short liquidations happen when price rises. Shorts are forced to buy back, and these passive buy orders accelerate the rally. But the fuel from short liquidations is limited. Once short positions are cleared out, that push disappears. If no spot buying follows after short liquidations end, price may fall back.
Large-scale long liquidations happen when price falls. Longs are forced to sell, accelerating the decline. Long liquidations can form a self-reinforcing spiral: price drops, longs get liquidated, selling pressure increases, price drops further, more longs get liquidated.
In judging what is driving a rally, liquidation data plays a confirming role. If price is rising but liquidations are mostly shorts with very few long liquidations, it means the rally is "cleaning out shorts" rather than "attracting new longs." This is closer to the profile of a spot-driven move.
A Practical Process for Making the Judgment
You do not need to become a derivatives expert to make this assessment. Open any platform that provides derivatives data. Coinglass is a common aggregator covering OI, funding rates, and liquidation data from more than 30 exchanges. Then follow this sequence:
Step 1: Look at the combination of price change and OI change. Is price rising while OI is falling or rising? Falling suggests spot-driven. Rising suggests new leverage may be entering.
Step 2: Look at the funding rate. Is the rate extreme? If price is up, OI is down, and the rate is moderate, this combination leans spot-driven. If price is up, OI is up, and the rate is spiking, it leans leverage-driven.
Step 3: Look at the liquidation distribution. Are recent liquidations mostly shorts or mostly longs? If the rally is mainly liquidating shorts without signs of large new long positions opening, spot buying is likely the main driver.
Step 4: Check the spot market for confirmation. Is Spot Relative Volume (SRV) significantly above average? In that August 2026 rally, SRV reached 2.94, nearly three times the 30-day average. This provided additional evidence that spot buying was dominant.
An Important Limitation
These indicators are diagnostic tools, not predictive tools. They tell you what the current market structure looks like, not where price will go. A spot-driven rally can still reverse because of macro events, regulatory news, or simply demand drying up.
In September 2026, the Federal Reserve's "shock amplification index" warned that even when spot demand is solid, the buildup of leveraged positions can still amplify a mild shock into a chain reaction. Spot buying provides a floor of support, but what determines how violently a shock spreads is the leverage layer. This means: spot-driven does not equal safe, and leverage-driven does not equal inevitable collapse. The difference lies in how and how fast they fail.
If you want to track these indicators, Coinglass's free dashboard provides real-time data on OI, funding rates, liquidations, and long/short ratios. A Pro subscription unlocks real-time alerts and longer historical data. The data itself is a directional reference, not a precise liquidation forecast. Coinglass's liquidation heatmap is an estimate modeled from OI and assumed leverage distribution, not a direct output from exchange liquidation engines.
To judge real demand in the market, you ultimately need to look at price, OI, funding rates, and liquidations together, rather than relying on any single indicator.
