Solana is attracting fresh attention across crypto markets as a large portion of its options open interest reached expiry on Friday, putting SOL’s derivatives market under the spotlight alongside much larger Bitcoin and Ethereum options settlements.
About 65% of Solana options open interest on Deribit was tied to the September 25 expiry, according to market data reported ahead of the event. Key strike areas included $90, $105 and $125, while SOL was trading around $116 during Friday’s session.
The Deribit settlement took place at 08:00 UTC. The scheduled expiry has therefore already passed, and attention is now shifting toward what happens to SOL after those positions are settled or rolled into later expiries.
The options event does not automatically signal that SOL should move higher or lower. Instead, it gives traders another reason to monitor liquidity, hedging activity, futures positioning, funding rates, spot volume and volatility.
Why Solana Options Put SOL in Focus
The immediate reason is the size of the expiring open interest relative to the SOL options market.
Approximately 65% of Deribit’s Solana options open interest was scheduled to expire on September 25. The figure is significant because the event removes or settles a large amount of existing derivatives exposure at one time.
Options can also influence short-term market conditions through dealer hedging. Market makers that provide liquidity to options traders may hedge their exposure through the underlying asset or related derivatives. As SOL moves closer to or farther from important strikes, those hedges can change.
However, open interest should not be interpreted as a straightforward bullish or bearish bet. A single options position can be part of a spread, hedge or market-making strategy. The open-interest figure therefore tells traders where contracts are concentrated, not necessarily what every market participant expects SOL to do next.
That distinction becomes particularly important with Solana because its options market remains considerably smaller and less liquid than the major Bitcoin and Ethereum options markets.
The Three SOL Strike Levels Traders Are Watching
The most closely watched strike areas surrounding Friday’s expiry were $90, $105 and $125.
| SOL Strike | Why It Matters | Market Context |
|---|---|---|
| $90 | Important downside reference |
Well below recent spot prices |
| $105 | Closer to recent SOL pricing |
More relevant to near-term positioning |
| $125 | Upside call area | Above the recent $115–$118 trading range |
With SOL trading around $116, the $105 strike was relatively close to the underlying market, while $125 represented an upside area that was still above recent spot prices.
These levels should not be treated as guaranteed support, resistance or price targets. They are reference points showing where options positioning was concentrated around the expiry.
SOL Was Around $116 as the Expiry Arrived
Solana entered the expiry after a strong September move.
Market data showed SOL trading around $116 on September 25, with the session reaching roughly $118.4. On September 24, SOL traded between approximately $112.7 and $117.7, according to historical market data.
That recent price action is important because it puts SOL substantially above the $105 strike while still below the $125 call area that attracted attention in the options market.
The broader trend has also been supported by increasing institutional interest in U.S. spot Solana ETFs.
Solana ETF Flows Add a Separate Demand Signal
Options positioning is only one part of the current SOL story.
U.S. spot Solana ETFs recorded net inflows for 12 consecutive weeks through the week ending September 18, according to Solana Compass. The streak had brought cumulative net inflows to more than $1.4 billion, while the week ending September 18 alone recorded approximately $60.7 million of net inflows.
That data provides a different market signal from derivatives positioning. ETF flows measure capital moving into regulated spot investment products, while options open interest reflects outstanding derivatives contracts.
The two signals should therefore not be treated as interchangeable. But together they show why SOL has remained on the radar of both derivatives traders and investors seeking regulated exposure to the asset.
The institutional-flow picture is particularly notable because Solana’s ETF market is much smaller than Bitcoin’s. Even relatively modest dollar flows can therefore represent meaningful changes in the size of the Solana ETF asset base.
What Friday’s Options Expiry Changes
The main effect of the expiry is that a significant amount of existing derivatives exposure has now reached settlement.
Traders can close positions before expiry, allow contracts to settle or roll exposure into later-dated contracts. Market makers can also adjust their hedges as the contracts disappear from the active expiry.
This can change liquidity and volatility around the event, but the effect is not necessarily permanent.
For SOL, the impact should also be viewed in the context of its smaller options market. Price discovery continues to occur across futures and perpetual markets on other exchanges, meaning a large move in SOL cannot automatically be attributed to the Deribit expiry.
Post-expiry trading conditions may therefore be more informative than the expiry itself. If SOL moves sharply, traders will need to examine spot volume, futures open interest, funding and broader crypto-market conditions before deciding what drove the move.
Bitcoin and Ethereum Expiries Make Friday More Important
Solana’s options expiry occurred alongside much larger Bitcoin and Ethereum derivatives settlements.
Market reports put the Bitcoin options expiry at roughly $15.9 billion and Ethereum at about $2.1 billion. Both were scheduled around the same major quarterly settlement window.
That creates a broader market context for SOL.
Bitcoin remains the largest source of liquidity and risk direction across the crypto market. A significant move in BTC following its much larger derivatives settlement can affect altcoins, including Solana.
Conversely, if Bitcoin remains relatively stable, SOL-specific factors such as ETF flows, network developments and its own derivatives positioning can become more visible.
This is why traders are watching SOL together with BTC and ETH rather than treating Friday’s Solana expiry as an isolated event.
Alpenglow Remains a Major Upcoming Solana Catalyst
Another reason SOL remains in focus is Solana’s planned Alpenglow consensus upgrade.
There is an important timing clarification here. Earlier reports described September 28 as a possible Alpenglow-related date, but it should not be presented as a confirmed Alpenglow mainnet activation date. Solana Compass reported that the September 28 entry in Anza’s Agave v4.3 schedule refers to the resumption of feature activation on mainnet-beta, rather than a confirmed Alpenglow activation date.
As a result, the exact mainnet activation date should be treated as unconfirmed until Solana developers announce it.
The upgrade remains an important development for the network because Alpenglow is designed to change Solana’s consensus architecture and improve finality performance.
For SOL traders, the distinction matters. A protocol upgrade can become an important market narrative before activation, but the existence of a development milestone does not provide a guaranteed short-term price signal.
Solana’s Network Performance Is Also Evolving
Alpenglow is part of a broader effort to improve Solana’s consensus and network performance.
The Agave v4.3 release carrying Alpenglow is designed to introduce major consensus changes, including improvements to finality and fault tolerance.
Solana has also been making changes to network timing and performance. Recent reporting around the network’s slot-time adjustment highlighted a move toward faster block processing, although a shorter slot does not automatically translate into a proportional increase in total network capacity.
For investors, the important distinction is between technical development and immediate token-price impact. A protocol upgrade can improve the network’s capabilities without producing an immediate or predictable change in SOL’s market price.
What Traders Should Watch After the Expiry
1. Spot Trading Volume
A major SOL price move accompanied by stronger spot volume provides more information than a move occurring in thin trading conditions.
2. Futures Open Interest
Futures open interest can show whether traders are adding new leveraged positions or reducing existing exposure after the options settlement.
3. Funding Rates
Perpetual futures funding rates provide another indication of positioning. Extremely one-sided funding can signal crowded leverage, although funding by itself does not predict the next price move.
4. Options Volatility
After the September expiry, traders can compare implied volatility across later SOL expiries. Changes in volatility pricing can show whether the market is assigning more or less risk to future price swings.
5. ETF Flows
Continued inflows into U.S. spot Solana ETFs would represent an additional demand signal. A reversal into sustained outflows would provide a different indication and should be assessed separately from derivatives data.
6. Bitcoin’s Post-Expiry Behavior
Because Bitcoin’s options settlement was substantially larger than Solana’s, BTC’s reaction can influence overall crypto-market liquidity and risk appetite during the next trading sessions.

What the SOL Options Expiry Means Now
Friday’s expiry has removed a significant portion of the SOL options positions that had been concentrated around the $90, $105 and $125 strikes.
But the expiry itself does not provide a simple directional signal for Solana.
With SOL around $116, the market entered settlement between the $105 and $125 areas that drew the most attention. The more important question now is how traders reposition for later expiries and whether spot and futures markets confirm any move that follows.
At the same time, the options event is only one part of the broader SOL story. The 12-week streak of U.S. spot Solana ETF inflows provides a separate institutional-flow signal, while the continuing Alpenglow development gives the network another long-term catalyst.
That combination explains why Solana remains in focus even after the Friday settlement has passed.
Bottom Line
Solana’s September 25 options expiry was notable because roughly 65% of Deribit’s SOL options open interest was tied to the event, with key strike areas around $90, $105 and $125.
The scheduled 08:00 UTC settlement has now passed, shifting attention from the expiry itself to the market’s post-settlement positioning.
SOL was trading around $116 during Friday’s session, while U.S. spot Solana ETFs had recorded 12 consecutive weeks of net inflows and more than $1.4 billion in cumulative inflows through the latest reported period.
Meanwhile, Alpenglow remains an important upcoming Solana development, but its exact mainnet activation date has not been confirmed. The September 28 date should not be described as a confirmed Alpenglow activation date.
For traders and investors, the next useful signals are spot volume, futures open interest, funding rates, options volatility, ETF flows and Bitcoin’s reaction to the broader derivatives settlement.
The options expiry is a market event, not a prediction. What happens next will depend on liquidity, positioning, new demand and broader crypto-market conditions.
