Crypto Whales Snap Up UNI, ORCA, and PUMP in September 2026

During the first 30 hours of September, crypto whales bought three alternative coins. Bitcoin has closed lower in September five times in the last eight years.

The broader market started the month 2.2% lower than Tuesday's high, so the whale buying was against the trend.

Uniswap (UNI)

On September 2, Nansen-labeled crypto whale wallets increased their UNI holdings from 3.20 million to 3.46 million tokens, a gain of 257,777 UNI valued at roughly $1.62 million. The number of wallets in this group rose from eight to nine, indicating a new major holder came in.

Supporting flows confirm the pattern. New wallets added $2.91 million, while exchange reserves dropped by 351,274 UNI, according to Nansen wallet data. UNI has risen 9% in the past day and 47% over the week, and it reappears on this list following whale purchases in July.

On-chain activity supports the accumulation. Uniswap recorded $2.69 billion in daily trading volume and $10.7 million in fees, per DeFiLlama protocol data. These fees fuel the UNI burn mechanism approved in December, meaning increased trading reduces the circulating supply.

Two cohorts took a hedging approach. Derivatives traders reduced their UNI exposure by $854,910 while maintaining a net long position, and the whales were net sellers of $130,256 on decentralized exchanges despite rising balances, suggesting they locked in some profits.

Orca (ORCA)

Orca presents the clearest contrarian case among the trio. Whale wallets labeled by Nansen increased their ORCA holdings from 160,325 to 201,097 tokens, a 25.4% surge, even as the token price dropped 1.3%.

The number of wallets in the cohort remained at 10, so current holders were the buyers. Exchange reserves fell by $263,753 in a single day, the second biggest withdrawal in 30 days, removing sell-side inventory. For this token, retail and whales appear aligned.

However, the weekly trend is less bullish. Over seven days, whale flows remain negative by $417,113, indicating that one strong day hasn't reversed a week of distribution.

Pump.fun (PUMP)

PUMP shows the greatest divergence in signals. Whale balances increased by 62.75 million tokens, valued at approximately $272,000, and new wallets added $1.83 million despite a 3.5% price decline.

The opposing forces are stronger. Smart traders offloaded $475,249, wallets with the highest profits sold $1.80 million, and exchange flows reversed from an $885,645 outflow to a $739,671 inflow within the same period. Tokens entering exchanges typically precede selling.

Pump.fun itself is a significant buyer. The firm states it uses half of all its revenue to purchase PUMP on the open market and then burns those tokens, permanently removing them. In the most recent day, it burned $997,700 worth.

While this reduces supply, it has never stopped price declines when sellers outpaced the company's purchases. At the start of September, whale wallets held 4.745 billion PUMP. If holdings drop below that level, the sellers would be dominant.

Analyst’s View: This does not signal a broad altcoin rally. Instead, it targets three tokens with a guaranteed buyer, occurring in a month when Bitcoin typically declines.

A buyback program provides a single consistent purchaser, not evidence of wider demand. In all three instances, the whale group sold on decentralized exchanges even as their balances increased, meaning higher balances reflect larger holdings, not open-market buying.

Among the three, UNI has the strongest supporting evidence, ORCA shows the most pronounced divergence, and PUMP presents the most conflicting signals.
