If you had to describe Ethereum whale behaviour in Q3 2026 in one word, it would be undecided.
We track 20,000+ Ethereum whale wallets and score their combined flow every day on a 0–100 Whale Sentiment Index (50 is neutral). Over the 92 days from July 1 to September 30, the index averaged 49.3 — almost exactly neutral — while swinging between 17 and 89.
Sentiment: three months, three moods
| Month | Average | Range |
|---|---|---|
| July | 52.6 | 17–85 |
| August | 46.4 | 20–89 |
| September | 49.0 | 17–76 |
- 40 days closed at 50 or above; 52 closed below.
- The quarter's high was 89 on August 26; the low was 17, hit on both July 22 and September 13.
- September closed at 21, well below neutral.
A neutral average hides the spread: the quarter covered almost the whole scale, from 17 to 89.
DEX swaps: August was the busy month
These are real trades on decentralized exchanges made by tracked whale wallets:
| Month | Swaps | Wallets | DEX buys | DEX sells |
|---|---|---|---|---|
| July | 7,427 | 198 | $26.2M | $20.4M |
| August | 10,957 | 310 | $188.4M | $133.2M |
| September | 12,960 | 255 | $148.2M | $139.7M |
Swap count rose every month, but the dollar volume peaked in August. In September, buys and sells were nearly balanced ($148.2M vs $139.7M).
September exchange flow: dollars left exchanges
Exact exchange-flow data is kept for 30 days, so the exchange numbers below cover September 6–30 only.
- Stablecoins: tracked whales withdrew $2.20B of USDC from exchanges and deposited $415.6M. For USDT it was $1.35B out and $687M in.
- Directional tokens: $688.8M withdrawn vs $340.2M deposited — a 66.9% withdrawal share. LINK, UNI, QNT and ONDO each had $37M–$45M net leaving exchanges.
- 97.4% of all whale-scoped dollar volume was exchange transfers, not trades. We wrote a separate study on why that matters: 97% of whale flow is exchange transfers.
Coins leaving exchanges is conventionally read as accumulation-side flow, and arriving coins as distribution-side flow. Those are labels for past movement, not forecasts.
What we changed during the quarter
The tracked universe was rebuilt around real holdings: admission now requires at least $250K in holdings, and market-maker and exchange-desk wallets were removed. That makes the numbers above closer to what actual large holders did, rather than what infrastructure wallets shuffled.
