3 Meme Coins to Watch in September 2026: Who Is Buying and Who Is Quietly Selling

Meme coins enter September rising but trailing, and the gap is not small. The sector’s top-10 basket gained 10.24% over 30 days while a comparable altcoin basket gained 40.28%, a 30-percentage-point lag, per CoinGecko data.That mismatch makes the meme coins to watch in September a selection problem, not a sector bet.

Three names stand out, one leading with a supply question, one diverging quietly, and one rallying into visible selling.

Pudgy Penguins (PENGU): The Leader With a Supply Test

Pudgy Penguins (PENGU) is up 47.45% in seven days and 60.02% in 30, beating the broader altcoin basket by nearly 20 points even without an altcoin season setup, per CoinGecko.

The move has a fresh feeder, since the Schleich collectible figurines from the Pudgy Penguins partnership go on sale August 28, right at September’s doorstep.

That attention is already showing up in the wallets. Nansen’s labelled cohorts show fresh wallets adding $427,000 and top-PnL wallets $611,000 over seven days, and Binance top traders sit far more bullish than the crowd, so new and sophisticated money agree.

The same Nansen data also holds September’s test.

Nansen also shows $7.50 million flowing into exchange wallets. This can signal possible sell pressure. Therefore, the buyers the figurines attract must absorb that supply for the rally to extend.

Shiba Inu (SHIB): The Quiet Divergence

Shiba Inu (SHIB) looks weakest on the surface, up just 13.58% in seven days and still down 22.26% this year, per CoinGecko. Underneath, tracked DEX buys exceeded sells by $30.39 million over seven days, a +69.82% demand skew, per Dune data. This price-to-buying divergence is one of the key September catalysts for this OG meme coin.

The same quiet buying shows on exchanges, where $1.97 million left trading venues, an outflow that can indicate possible accumulation, per Nansen. Japan gives that accumulation a September storyline, as the FSA register lists SHIB among six assets authorized for Nomura-backed Laser Digital Japan, potential future institutional access with no launch date yet.

The catch is who is selling. Top-PnL wallets cut $824,000, so the catch-up case stays unconfirmed until that cohort turns.

Official Trump (TRUMP): The Rally Meeting Distribution

Official Trump (TRUMP) has the loudest tape, up 29.44% in seven days with volume running 6.5 times its monthly norm. Fresh wallets added $5.85 million, the largest new-money reading of the three.

However, that new money is walking into busy exits. Nansen shows $18.33 million moving into exchanges, whales cutting $375,000, and Binance top-trader conviction falling through the same rally the fresh wallets are chasing.

Wallets described as team-linked, supposedly netted $3.39 million through liquidity cycling, though the project has not confirmed the attribution.

Fresh demand meeting sophisticated selling is the classic fade setup, and heading into September it holds only while new buyers keep arriving.

TRUMP Demand Versus Supply: BeInCrypto

Analyst’s View: Here is the detail that frames September for these meme coins to watch. Over the past 60 days, memes captured only about 70 cents of every dollar the altcoin basket gained, so even a genuine meme season starts the month from behind.

That is why the exchange columns matter more than the charts. PENGU confirms its bullish setup if its inflow reverses. SHIB confirms if the profitable wallets stop selling. And finally, TRUMP’s setup turns bullish only while fresh buyers outrun the exits.
