When SOL outperformed BTC
Last reviewed 2026-09-21Source: CoinGecko daily close series for SOL and BTC; Messari and Solana Foundation documentationOutperformance windows are identified from the cited daily series. Coinciding events are listed as context, not as causes.
How outperformance is measured
Outperformance is measured on the SOL/BTC ratio, which is SOL's daily close divided by Bitcoin's on the same date. A window is counted as an outperformance period when the ratio rises over it, which means SOL gained more than Bitcoin if both rose, or lost less than Bitcoin if both fell. The series are the CoinGecko daily closes from August 2020 to the last complete month before this page's review date.
Using the ratio rather than comparing two separate return figures is deliberate. It removes the common market factor and leaves the relative move, so a window in which both assets rose 50% and 30% respectively is correctly described as SOL outperforming, even though both returns are positive. The construction is described in more detail on the ratio page.
The windows below are identified by the ratio's direction over a sustained period rather than by single-day moves. A one-day divergence is noise; a window is only listed when the ratio moved in one direction over a stretch long enough to be visible on a weekly chart.
The documented windows
| Window | Ratio direction | What coincided with it |
|---|---|---|
| Early 2021 | Rose | A broad expansion across the risk-asset complex, with SOL's market still forming and its venue coverage widening. The move coincided with the wider market's advance rather than with a single network event. |
| Mid 2021 | Rose, with interruptions | Continued expansion interrupted by network congestion episodes. The ratio advanced over the window but with visible setbacks around the periods when the network was degraded. |
| Late 2021 | Rose to the record high | The peak of the cycle for the ratio. The advance coincided with the final stage of the market expansion, when smaller assets typically outperform before the turn. |
| 2023 | Rose from the trough | A recovery phase with comparatively few asset-specific shocks. The ratio regained part of what it lost in 2022, and the move coincided with a market-wide repricing rather than with a Solana-specific development. |
| Recent period | Mixed, with shorter windows | Shorter and less sustained outperformance windows, several of which coincided with network or ecosystem announcements. None of these windows is long enough to establish a pattern. |

Coincidence is not causation
Every window in the table above has something that coincided with it. That is not a finding; it is a property of looking at a price chart with a news feed open. There is almost always an announcement, a listing, an upgrade or a macro event near any sustained price move, and selecting the one that appears to fit after the fact is the most common error in this kind of writing.
The honest statement about these windows is narrower than it first appears. The ratio rose over each of them, which means SOL outperformed Bitcoin over that period. What caused the outperformance is not established by the price record, and this page does not claim to establish it. A reader who wants a causal account would need evidence that is not in a price series: order flow, positioning, or a documented mechanism connecting the event to the price.
There is also a selection problem in the other direction. Windows in which SOL underperformed are just as numerous, and the drawdown comparison covers the largest of them. A page that listed only the outperformance windows and their coinciding events would give a systematically misleading impression, which is why the underperformance record is treated with equal weight elsewhere in this strand.
The common factor explanation
The most parsimonious explanation for the largest windows is the market factor rather than anything specific to Solana. Smaller, higher-beta assets tend to outperform at the late stage of a liquidity expansion and to underperform at the turn, and the largest outperformance window in this record sits exactly where that pattern would place it. That is a description of a well-documented market-structure regularity, not a claim about Solana's technology.
The shorter windows are harder to explain with the market factor alone, because they occurred when the wider market was not moving much. Those are the windows where an asset-specific explanation is most plausible, and they are also the windows where the evidence is weakest, because a short window contains less information and is more easily explained by noise.
The distinction between the two kinds of window is the useful output of this page. A long outperformance window that coincides with a market-wide expansion is best read as a market phenomenon. A short window that coincides with a network event is a candidate for an asset-specific explanation, and it is a hypothesis rather than a result.
What this page does not claim
This page does not claim that any event caused any price move. The windows are documented from the ratio, and the coinciding events are listed as context. Establishing causation would require evidence outside the price record.
The page also does not claim that SOL outperforms under any particular condition. The record covers one cycle, and there is only one observation of each phase, which is not enough to support a rule.
Dataset, period, method and limitations
- Dataset
- CoinGecko daily close series for SOL and BTC, with ecosystem and network context cross-checked against Messari and Solana's official status record.
- Period
- August 2020 to the last complete month before the review date, covering the 2021 expansion, the 2022 contraction and the recovery that followed.
- Method
- Outperformance is measured on the SOL/BTC ratio. A window is listed when the ratio moves in one direction over a sustained stretch, long enough to be visible on a weekly chart, rather than on single-day moves. Coinciding events are listed as context only.
- Limitations
- The window boundaries are editorial, and a different rule would produce a different list. The record covers one cycle, so it cannot support a claim about how often SOL outperforms or under what conditions. The page does not adjust for liquidity or for the cost of transacting.
Where this sits in the wider record
This page is the outperformance half of the relative record; the drawdown comparison is the underperformance half. The correlation page covers how tightly the two assets moved together over the same windows, and the bull and bear phase page places the windows inside Bitcoin's cycle structure.
For the architectural comparison between the two networks, which is a separate question from their price behaviour, see Bitcoin vs Solana architecture.
