Solana, XRP and Cardano all traded lower on October 26 while Bitcoin dominance stayed above the 60% threshold, keeping the market stuck in a pattern that has favored the largest asset for months. Solana changed hands near $101, XRP around $1.29 and Cardano near $0.20, with the three posting modest declines of roughly 0.4% to 0.8% for the day. BNB was nearly flat.
The moves themselves are small. The bigger story is the backdrop: an Altcoin Season Index reading of about 52, far below the 75 mark that typically accompanies a broad altcoin rally.
The dominance problem
Bitcoin's share of the total market holding above 60% is the number that matters most for altcoin holders right now. When dominance stays elevated, capital tends to stay parked in BTC rather than rotating down the risk curve. That's exactly what the index is reflecting — a handful of large-cap names doing the heavy lifting while the rest of the market treads water.
Solana near $101 is a long way from where it traded during its strongest stretches, and the token's daily drift lower suggests buyers aren't rushing in at this level. XRP and Cardano are showing the same lack of conviction.
Solana ETFs: flows are the tell
The US Solana ETF complex held roughly $1.69 billion in assets as of October 21, with cumulative net flows of about $1.56 billion. That's a real institutional footprint, and it's the kind of number that would normally support a bullish narrative.
But the flow pattern in October has been uneven. Several days of outflows hit the funds before a small positive flow returned on October 21. For a product category that was supposed to be a steady bid for SOL, the choppiness is a warning sign. Institutional demand hasn't disappeared — it's just stopped being one-directional.
What CME's new index says about the altcoin trade
CME Group's Emerging Crypto Index tracks ten assets outside Bitcoin and Ethereum: XRP, BNB, Solana, Hyperliquid, Chainlink, Stellar, Uniswap, Sui, Avalanche and Aave. The composition is worth noting. It's a basket built for regulated exposure to the altcoin sector, and it lines up with the assets that would need to participate for an altcoin season to be genuine rather than a two- or three-name rally.
So far, the broader market gains beyond SOL, XRP and BNB haven't shown up. That's one of the conditions that would need to change before the index reading of 52 starts moving toward 75.
The Fed meeting looms
The Federal Reserve meets October 27–28, and economists widely expect rates to stay at 3.75%–4.00%. That expectation is doing a lot of work in the current market. Persistent inflation means additional rate increases remain possible, and any hint of that on Wednesday would likely hit altcoins harder than Bitcoin.
For now, the checklist for an actual altcoin season remains unmet. A sustained decline in Bitcoin dominance would be the first sign. An Altcoin Season Index above 75 would be the confirmation. Broader gains across the market — not just the three or four largest names — would be the proof. And continued institutional demand for altcoin ETFs and regulated products would need to stop looking so erratic.
None of those boxes are checked heading into the Fed decision. The next concrete test is Wednesday's statement and press conference, where the rate path for the rest of 2026 could either loosen the pressure on altcoins or tighten it further.
