Weekly Meme Coin Data Report — 9.7–9.13, 2026

By MemeFee Research · Published 2026-09-13

The eight-token board fell from $22.2B to $19.4B (-12.5%) on UTC closes, erasing most of the prior week's +10.4% rebound. Every closing print was red except WIF's trailing-7-day live read; SPX led the fall at -13.0%.

Method first, because every claim below depends on it: prices are UTC daily closes from CoinMarketCap, CoinGlass, CoinLore and BitKan history pages (linked in Sources); weekly change is close-to-close between the boundary dates; the combined board cap is the sum of our eight members' tracker caps on the latest published close at or before each boundary. Where a coin's history page had not yet published a Sep 12 close at press time (SHIB, FLOKI: Sep 11; PENGU: Sep 8; BONK, WIF: Sep 7), we use that close and date it in the table. No estimates, no interpolated numbers.

1. Core metrics — week-over-week

Metric	Sep 6	Sep 11–12	Change
Board combined market cap (8 tokens)	$22.19B	$19.43B	-12.5%
DOGE close	$0.09082	$0.08485 (Sep 12)	-6.6%
DOGE market cap	$15.58B	$13.23B	-15.1%
Board equal-weighted close change	—	—	-5.4% avg (7 red closes + WIF live read)

The week undid the prior week's rebound almost exactly: the board's +10.4% climb from $20.11B to $22.19B reversed to $19.43B, which is 3.4% below where the August 30 close sat. Three weeks, three directions: -5.6%, +10.4%, -12.5%. A descending staircase of volatility, not a trend.

2. The eight-token board — closes and weekly change

Coin	Sep 6 close	Week-end close (as-of)	Weekly change
DOGE	$0.09082	$0.08485 (Sep 12)	-6.6%
SHIB	$0.000005525	$0.000005172 (Sep 11)	-6.4%
PEPE	$0.00000365	$0.00000340 (Sep 12)	-6.8%
PENGU	$0.00878	$0.00833 (Sep 8)	-5.1%
SPX	$0.577	$0.5021 (Sep 12)	-13.0%
BONK	$0.00000341	$0.00000316 (Sep 7)	-7.3%
FLOKI	$0.0000264	$0.0000245 (Sep 11)	-7.2%
WIF	($0.2030 Sep 5 / $0.2160 Sep 7)	+9.2% trailing 7d (live Sep 15)	green

WIF's row is different on purpose: its history pages had no Sep 6–12 closes published at press time, so we quote Forbes' live trailing-7-day read (+9.23% as of Sep 15, cap ≈$214M) instead of inventing a closing print. It is the only green row on the board either way.

3. What the shape of the week says

The breakdown was orderly, not panicky. DOGE's worst day was -4.0% (Sep 11, close $0.08428 from $0.0878's false break of $0.09); PEPE's worst was -6.9% (Sep 10). Nothing on the board printed a -15% day.
Volume told the same story. DOGE traded $929M on the Sep 11 break, then $346M on Sep 12 (CoinMarketCap) — conviction thinned as price fell, the opposite of capitulation's signature.
The damage was proportional to the prior week's gain. BONK (+22.2% the week before) fell 7.3% on its latest close; PENGU (+2.0% prior week) fell 5.1%. The board did not discriminate randomly — it unwound in the order it had risen.
SPX is the exception that proves it. It rose +7.1% in the rebound week and fell the most this week (-13.0%), completing the cleanest round-trip on the board.

4. Three-week pattern: a failed V

Week	Board cap	Week change	Character
Aug 24–30	$20.11B (from $21.31B)	-5.6%	7 of 8 red; SPX only green
Aug 31 – Sep 6	$22.19B	+10.4%	8 of 8 green; BONK +22.2% led
Sep 7–13	$19.43B	-12.5%	7 of 8 red; WIF only green (live read)

Read the three weeks together and the market's message is unambiguous: the September bounce could not hold above the August 30 base. $19.43B is 3.4% below $20.11B. The rebound tested the base from above, failed, and the failure took six sessions.

5. Versus the broader market

Bitcoin closed September 12 near $77,310, up modestly on the day and described by Moneynomical's wrap (Yahoo Finance data) as a 'quiet, broadly positive' session — nine of ten tracked majors gained. The meme board fell 12.5% into that backdrop. This is rotation within risk, not risk-off: money left the highest-beta corner while the anchor held. The last time the two diverged this hard in opposite directions was the August 24–30 week, and the board mean-reverted upward the following week — though a single precedent is a observation, not a law.

6. Level watch

Level	Why it matters	Status at week-end
DOGE $0.08	Round-number floor; the August base sat just above it	$0.08485, cushion 6%
SHIB $0.000005	Defended Aug 30; 200-day MA region above	$0.000005172 (Sep 11) — 3.4% above
PEPE $0.00000364	200-day EMA, rejected Sep 9	Closed below at $0.0000034 (Sep 12)
SPX $0.52	September 12 low $0.4664 intraday	Closed $0.5021 — inside the air pocket

7. What would change our read

A board close back above $20.1B (the August 30 base) on rising combined volume would invalidate the failed-V read.
DOGE holding $0.08 on a daily-close basis for three sessions would mark the first higher low since the September 11 break.
PEPE's 10M–100M cohort flipping to net accumulation (Santiment cohort data) while price reclaims the 200-day EMA — the two have not aligned positively since August 25.
Bitcoin losing $75,000 would reframe the meme drawdown as part of a broader risk-off rather than sector rotation — and would remove the 'rotation' thesis from this report entirely.

8. Methodology & data notes

Closing prices: CoinMarketCap (DOGE, SHIB, PEPE), CoinGlass (PENGU, SPX, WIF), CoinLore (FLOKI), BitKan/TokenInsight (BONK). Cross-checks noted in [market_intelligence] where sources differ.
Board cap = sum of member caps on each tracker's own figure. BONK's cap varies by up to ~15% across trackers because circulating-supply estimates differ; we use close × ~88.8T circulating consistently and say so.
The board is the eight largest meme assets by market cap excluding wrapped/pegged duplicates: DOGE, SHIB, PEPE, PENGU, SPX, BONK, FLOKI, WIF (Forbes meme-category order).
All history pages are linked in Sources. Every figure in this report can be re-derived from them in minutes.

FAQ

Why does the report use closing prices instead of live prices?

Because closes are checkable forever. A live price matches only the second you read it; a UTC daily close on a public history page can be re-verified months later by anyone. Our weekly comparisons are all close-to-close for exactly that reason.

Why is the combined board cap not the whole meme sector?

Because 'the whole meme sector' depends on a tracker's inclusion rules — Forbes' table, CoinGecko's category and CoinMarketCap's category disagree on membership and on wrapped tokens. Summing our fixed eight members with dated as-of points is narrower but reproducible. We label it 'board combined cap' everywhere so it is never confused with a sector total.

SHIB and FLOKI show Sep 11 closes while DOGE shows Sep 12 — is that sloppy?

It is honest. At press time those history pages had not published a Sep 12 row. Substituting a live read would make the number unverifiable tomorrow; dating the last published close keeps every cell checkable. The as-of date is printed in the table for every such row.

The prior week's report said +10.4%; this one says -12.5%. Is the board just noise?

Three weeks of -5.6%, +10.4%, -12.5% is high volatility, but it is structured noise: the unwind ran proportional to the prior week's gains, the volume thinned as prices fell, and the whole move happened while Bitcoin held level. Structure is what separates a readable market from a random one.

How do I verify the -12.5% board figure myself?

Sum the eight caps on Sep 6 closes (linked in Sources) — you should land near $22.19B — then repeat with each coin's latest published close at or before Sep 12, landing near $19.43B. The deltas are the arithmetic of the report; if your sum differs materially, check which as-of dates you used, because that is the only free variable.
