ARB Jumps Six Ranks on 16% Daily Gain as CMC Top 10 Freezes

CoinMarketCap's top 10 sits unchanged as of 15:00 UTC on 16 Sep, with the only boundary action at rank 99-100: FDUSD slipped in at #99 while BSV dropped out after a 3.6% daily decline left both assets near 0.33 billion in market cap. The mid-band told a sharper story.

The numbers

Token	Rank	Delta	24h
ARB Arbitrum	#57	▲ 6	▲ 16.4%
U United Stables	#48	▲ 3	0.0%
PI Pi Network	#63	▼ 7	▼ 13.3%
AAVE Aave	#42	▼ 4	▼ 6.2%
HBAR Hedera	#28	▼ 3	▼ 6.0%

ARB posted the session's largest combined rank and price move, climbing from 63 to 57 on a 16.4% gain to 1.07 billion in market cap. Stablecoin U added three ranks on flat pricing, implying the shift came from competitors above it losing value rather than its own appreciation.

On the downside

PI fell hardest, shedding seven ranks and 13.3% in 24 hours. The fallers cluster skews toward DeFi and L1 infrastructure — AAVE, SKY, STX, HBAR — all down 6% or more. Net rotation was roughly balanced: one entry, one exit, mixed internal flows.
