Solana at a Three-Month High: What Is Holding the SOL Price Up as ETF Inflows Dry Up

Solana stands at $117.79 on Monday and therefore above every hourly price of the past 90 days. The previous high of that span was $114.02 on September 18 at 20:00 UTC, and the live price sits 3.3 percent above it, having reached 118.19 during the day (CoinGecko, hourly series of 2,161 values, retrieved on September 21, 2026 at 17:24 UTC). Over 24 hours the gain is 7.35 percent, over seven days 15.36 percent, over 30 days 26.37 percent.

On the monthly scorecard Solana is the strongest of the five largest assets: BNB manages 15.96 percent over the same period, Ethereum 14.34, Bitcoin 11.74, XRP 3.60. Anyone who wants to place the wider market will find the reading for all major assets in our overview of crypto prices. For Solana itself a different question arises on Monday: where is the money coming from when the ETFs are barely supplying any?

Solana ETF inflows: twelve positive weeks, and ever smaller

The US spot ETFs on Solana have booked net inflows for twelve consecutive weeks and collected roughly $1.4 billion in the process, with assets under management at $1.62 billion (Solana Compass, September 20, 2026). The direction holds. The order of magnitude no longer does: in the week to August 28 the figure was still $153.87 million, in the week to September 4 it was $6.18 million. For the week to September 18, Solana Compass gives $60.7 million while SoSoValue's count arrives at $13.2 million. The gap comes down to which products are included, and both numbers are a fraction of what late August delivered.

Around 80 percent of the inflows land in a single product, Bitwise's BSOL, the only one that passes staking income through to investors: $1.145 billion in assets, 10.09 million SOL staked, a net annual yield of 5.31 percent. The products from Grayscale, Fidelity, VanEck and Morgan Stanley offer price exposure alone and take in correspondingly little.

To gauge what these inflows can actually move: $13 million to $61 million in a week equals 0.02 to 0.09 percent of the $69.2 billion market capitalisation. A seven percent daily gain does not come out of that. For comparison, the US Bitcoin ETFs booked $6.1 million in the same week, their quietest since October 2024. For both coins, ETF money is not carrying the current move.

What is moving the Solana price instead: forced buybacks and volume

Monday was a day of short liquidations across the market. According to CoinGlass data summarised by CoinDesk, positions worth $746.6 million were closed by force within 24 hours, $647.9 million of them bets on falling prices. Open interest across all futures markets rose 7.59 percent to $156 billion. How this squeeze lifted four of the five largest coins above their quarterly high at once is set out in our analysis of the Bitcoin advance beyond $84,000.

Solana carries one feature that stands out in the comparison: its 24-hour trading volume of $6.40 billion equals 9.2 percent of its market capitalisation. For Bitcoin the figure is 3.1 percent ($54.09 billion against $1,728 billion), for Ethereum 7.2 percent. Relative to its size, then, Solana trades three times as heavily as Bitcoin. That is why SOL runs harder than the market on days like this one, and it is the same reason it falls harder on pullback days.

The Solana network: 250 milliseconds per slot since September 18

On September 18 the Solana mainnet cut its target slot time from 300 to 250 milliseconds, the third stage of proposal SIMD-0525 after the steps from 400 to 300 milliseconds. Block production rises by almost 17 percent as a result, and an epoch now takes around 30 hours instead of 36 (KuCoin News). This is not the Alpenglow update, which rebuilds consensus and targets finality of roughly 150 milliseconds; that has a timetable of its own.

For the price the slot time is no driver, though for context it matters: the September 18 high that was beaten on Monday fell on exactly that day. What stakers and holders should have been checking since then is covered in our analysis of the seven-month high of September 18.

The Solana price levels: 114, 120 and the distance to the all-time high

Three numbers frame the price. First, $114.02, the old high of September 18: if the price holds above it, the breakout was real; if it slips back below, this was a squeeze spike of the kind seen in Monero, which set a fresh 90-day high on Monday and trades seven percent lower. Second, the $120 mark, named as the next target in our Solana price prediction of September 18, which the daily high of 118.19 came within 1.5 percent of. Third, the all-time high: despite the rally, SOL sits 59.8 percent below it (CoinGecko). Solana is not an asset breaking records at the moment. It is one working its way back out of a deep valley, roughly 74 percent above its low of the past 90 days.

What to check before you buy SOL or start staking

First, the inflows: Solana Compass and SoSoValue publish the ETF flows weekly, Farside daily. If the run of twelve positive weeks breaks, the institutional demand argument for SOL is gone for the time being, and the price hangs on spot and derivatives alone. If the run continues at a level of $10 million to $60 million, it is background noise rather than a driver.

Second, open interest after the squeeze: if the price holds above $114 while open interest is unwound, the advance stood on genuine demand. If both fall together, it was forced. That test needs two to three days, not two hours.

Third, the yield: anyone holding SOL earns a running reward through staking, which BSOL passes on to its investors at a net 5.31 percent. Staking on your own delivers a higher gross yield, in exchange for carrying custody and withdrawal periods yourself. Which providers pay what and how the lock-up periods look is set out in our comparison of staking platforms. The terms for the purchase itself, with fees and euro deposits, are gathered in our overview of the best crypto exchanges.

Solana at a three-month high: what remains once the squeeze is over

The balance on Monday: Solana leads the big five over one month with 26 percent, stands above every hourly price since late June, and offers a staking yield that is filling the sector's largest ETF. What is missing is money from outside, because the ETF inflows have shrunk to a fraction since the end of August, and Monday ran on forced buybacks. The coming days will decide whether $114 becomes a floor. Only then is the breakout more than a squeeze.
