THE DOMINANCE DEBRIEF

Week of September 21 – September 27, 2026

Issue #28

The crypto market grew 4.07% and SOLDOM outran it, up 5.51%, the largest move of the week. USDTDOM fell 3.63%, BNBDOM fell 3.23% and ETHDOM fell 2.32%. BTCDOM closed almost exactly where it opened, down 0.02%.

1. THE WEEK IN DOMINANCE

The total crypto market grew 4.07% this week, from roughly $2.75 trillion to roughly $2.86 trillion, and dominance sorted itself by pace. Solana Dominance rose 5.51%, the only pair here that genuinely outran the market; Solana itself gained 9.72% in price. Bitcoin Dominance closed at 58.89%, down 0.02%, tracking the market’s pace closely enough to leave its share almost untouched. Ethereum Dominance fell 2.32%, BNB Dominance fell 3.23%, and Tether Dominance fell 3.63%, each losing ground to a market that grew faster than they did.

2. MACRO CONTEXT — THE BACKDROP

Monday morning opened with a squeeze: Bitcoin ran from $81,169 to about $86,600 by Tuesday’s open, and roughly $647.9 million of short positions were liquidated across crypto in the following 24 hours, about $277.5 million of it in Bitcoin alone. US spot Bitcoin ETFs took in $2.39 billion across the five sessions, positive every single day, but the daily total shrank each day it ran: $999 million Monday, $714.7 million Tuesday, $346.9 million Wednesday, $190.7 million Thursday, $134.5 million Friday. That taper matters more than the headline total; a squeeze that keeps attracting less money each day it continues is not building momentum, it is spending it.

The market topped out near $2.90 trillion on Tuesday and into Wednesday morning, then gave some of it back Wednesday afternoon, with Bitcoin finishing that session near $84,400. Sources framed the pullback as profit-taking after the run rather than a reaction to any single headline.

Friday morning brought the quarter’s derivatives settlement: about $15.9 billion of Bitcoin options and about $2.1 billion of Ether options expired on Deribit at 08:00 UTC. Bitcoin’s max pain sat at $75,000, far below where spot was trading, and the book leaned call-heavy into the settlement. Sentiment tracked the week’s shape: Fear and Greed opened at 70, touched 78 (Extreme Greed) on Tuesday, and was back to 70 by Sunday.

The Structure

From August 19 to 27, Solana Dominance climbed from about 2.04% to a 2.37% daily close, with a high of 2.39%. It spent the first half of September consolidating, daily closes between 2.22% and 2.29% and lows as deep as 2.21%. September 18 broke that range, closing at 2.40% with a high of 2.42%, and the lows have stepped higher ever since: 2.21% in mid-September, 2.31% on September 20, and this week’s low of 2.34% on Wednesday. Friday cleared 2.42%, the level that had capped the pair since September 18, and the week closed at 2.49%, above it. That is a weekly close above former resistance. Sunday’s 2.53% high is the level still overhead.

This Week’s Price Action

Daily closes ran 2.39%, 2.39%, 2.37%, 2.40%, 2.50%, 2.48% and 2.49%, Monday through Sunday. Monday added a little ground during the squeeze, and Tuesday and Wednesday gave some of it back; the 2.34% low printed Wednesday afternoon inside the market’s pullback and held above the September 20 low. Thursday afternoon added about 1.4%. Friday did most of the week’s work, about 3.9% in a single session: the move started in the hour after the 08:00 UTC options expiry settled and ran through late morning UTC, with Solana’s price going from about $116.40 to about $120.90 while Bitcoin barely moved. The weekend held between roughly 2.46% and 2.53%, with a spike to the 2.53% high inside an hour Sunday morning that faded back to the 2.49% close. No catalyst for that Sunday spike has surfaced.

The Daily View

Read as a stair, not a ramp: three flat days, one step Thursday, one large step Friday, and a weekend that held the step rather than giving it back. The higher lows built since September 18 remain intact.

The Why

Two mechanisms did the work here, and both need naming. The market grew 4.07% on its own, which pulls every pair’s share down by default; Solana had to outrun that pace just to hold its ground. Solana’s price then rose 9.72%, more than twice the market’s growth rate, and that gap is where the 5.51% dominance gain comes from.

The asset-specific drivers behind that outperformance are concrete. US spot Solana ETFs took in $188.21 million across September 21 to 25, with every one of the seven funds positive on the week; Bitwise’s BSOL brought in $128.46 million of it and Grayscale $28.06 million. Friday alone drew $86.67 million, the largest single day. Flows print across the full US session rather than at a single moment, so Friday’s inflow landed after the morning’s move had already begun, not before it. On Thursday, September 24, Anza confirmed that Alpenglow had completed its handoff on Solana’s public testnet, retiring TowerBFT in favor of the Votor voting protocol and targeting roughly 150-millisecond finality against about 12.8 seconds today; Thursday afternoon’s step in dominance landed the same day. Mainnet activation has not happened. Anatoly Yakovenko has publicly dismissed talk of a September 28 mainnet launch, and mainnet timing is still unset. In the background, on September 20, ZetaChain tokenholders voted 99.4% to wind down their own chain and migrate ZETA to Solana as an SPL token.

The contrast that sharpens this: US spot Ether ETFs took in $689.9 million over the same five days, more than three and a half times Solana’s haul, and Ethereum Dominance still fell 2.32%. Inflow size alone does not decide dominance; what decides it is whether the asset outruns the market underneath it.

The Outlook

2.42% is the level the breakout now has to hold, former resistance sitting under the weekly close. 2.53% is the week’s high and the level a continuation needs to clear. 2.34% is the week’s low; a close back below 2.42% would say the breakout failed, and a close below 2.34% would break the stair of higher lows built since mid-September. Solana’s mainnet feature activations resume Monday under the Agave v4.3 schedule. The lean here is toward continuation, conditional on 2.42% holding.

4. THE DOMINANCE MATRIX

Ranked by magnitude, this week splits into a cluster and an outlier: Tether Dominance down 3.63%, BNB Dominance down 3.23%, Ethereum Dominance down 2.32%, and Bitcoin Dominance down 0.02%. The cluster’s three losses sit within a percent and a half of each other, but they arrived through different paths and on different timing.

Tether Dominance gave up its entire weekly decline in one session. Monday’s squeeze took it from 6.62% to a 6.28% daily close, and the low of 6.21% printed early Wednesday. From there it recovered, back to about 6.43% during Wednesday’s pullback, and spent the rest of the week holding between roughly 6.38% and 6.44%. The whole weekly loss sits in the opening session; after Monday, the pair actually gained ground as the broader market cooled. Tether’s own price held at $0.9997 throughout.

BNB Dominance lost share by lagging rather than by any single break. BNB itself rose 0.82% against a market up 4.07%, and BNBDOM bled from its 3.76% high in the small hours of Monday to a 3.57% low Wednesday afternoon, then went flat: daily closes of 3.62%, 3.60%, 3.58% and 3.60% from Thursday onward.

Ethereum Dominance ground lower almost every day of the week: 11.60%, 11.52%, 11.49%, 11.47%, 11.43%, 11.45% and 11.39%, Monday through Sunday. Its 11.80% high came in the opening hour and its 11.35% low late Sunday, two hours before the close. Ether rose 1.62% in price and still lost share, one of the cleaner illustrations in this issue that a price gain does not guarantee market share.

Bitcoin Dominance matched the market almost exactly on the week, Bitcoin’s price up 4.04% against a market up 4.07%, but the flat close hides a 1.77% swing inside it: a 59.74% high Monday evening at the height of the squeeze and a 58.70% low Friday afternoon, the same session Solana made its run. Bitcoin took in the week’s $2.39 billion of ETF money and used it to hold its share rather than grow it.

What this table doesn’t show is where the rest of the ground went. The pairs covered here held 83.26% of the total market at Monday’s open and 82.75% by Sunday’s close, and Solana Dominance’s gain only accounts for part of what Ethereum Dominance, Tether Dominance and BNB Dominance gave up. The combined share of these pairs fell because the wider market outpaced them, and that gap showed up in a broader week for trading and tokenization tokens, Hyperliquid’s HYPE and Uniswap’s UNI among them. This was an expanding market in which Bitcoin held its pace, Solana alone outpaced it, and the rest of the week’s share moved through the wider market rather than between these pairs.

5. THE WEEK AHEAD — EVENTS CALENDAR

Monday, September 28 — Solana mainnet-beta feature activations resume under the Agave v4.3 release schedule.

Tuesday, September 29 — Korea Blockchain Week opens in Seoul (main conference runs September 30 to October 1).

Wednesday, September 30 — US Core PCE, August (Consensus: 3.4% y/y | Prior: 3.3%).

What to Watch for Dominance: SOLDOM enters the week with 2.42% as the level the breakout has to hold and 2.53% as the level a continuation needs to clear. Friday’s payrolls print is the event that reprices the whole complex at once, and that matters most for USDTDOM given how completely this week’s decline was decided in a single session.

6. CLOSING REMARK

Solana Dominance grew faster than the market this week; Bitcoin Dominance only matched its pace, and the ground given up by Ethereum Dominance, Tether Dominance and BNB Dominance moved into a wider market that outpaced all three. That is the story a 4.07% market growth week tells when read through dominance rather than price alone.

What carries into next week is whether SOLDOM holds above 2.42%. The breakout is real on the close; whether it survives contact with a quieter week is the open question.
