ARB -2.5% in 15 min after 21:15 as Binance spot volume hits 2.9× normal; no onchain trigger

ARB held flat around $0.183–0.184 for most of the window, then fell to about $0.179 between 21:15 and 21:35. Most of the drop came in two minutes of heavy Binance spot selling at 21:31–21:32. ARB fell more than BTC and ETH and was already down 6.8% over 24h. Futures open interest fell, funding was normal and liquidations were tiny, so this does not look like a leverage flush. No onchain exchange inflow explains it, so the trigger is unknown.

What happened

Price traded in a tight $0.1830–0.1840 range from 19:30 to 21:15, slipped to $0.181045 by 21:30 and was at $0.17938 by 21:35. That is -1.96% over the window, -2.44% over 1h and -6.81% over 24h. The summary rounds the high and low to $0.2; the 15-minute data shows a high of $0.184019 and a low of $0.181045, and the current price is below that low. E1
Binance ARB/USDT traded $711.2K in the last hour against a typical hour of $242.3K (2.9×). Selling was concentrated in two minutes: 21:31 traded $224.6K at -0.552% and 21:32 traded $145.8K at -0.389%. E2
CoinGraph price-move signals fired at 21:29 (1h -1.61%, z 2.62) and at 21:34 (1h -2.51%, 15m -2.35%, z 4.03, high severity). E18
Binance futures open interest is $46.8M, down 2.14% vs 1h ago and 1.03% vs 4h ago. Forced liquidations in the window totalled only $9.2K across 14 orders ($8K longs, $1.2K shorts). E3 E6

Likely causes

1.A short burst of aggressive spot selling on Binance at 21:31–21:32 pushed price down. The seller's identity and motive are not visible in the evidence. (60%) E2 E1 E18
2.Weak market backdrop plus ARB-specific relative weakness. BTC fell 0.55% and ETH 1.09% over the same window, against ARB's 1.96%, and total crypto market cap is down 2.97% in 24h. (40%) E14 E1
3.Some long positions closing or de-risking. Open interest fell 2.14% in 1h and liquidations skewed long, but at $9.2K they are too small to have driven the move. (30%) E3 E6
4.No specific catalyst was found. There was no onchain exchange inflow and no news item in the evidence. (50%) E7 E8

Onchain

On Ethereum there were 89 ARB transfers worth $1.1M in the window, with $0 flowing onto or off tracked exchange wallets. E7
The largest transfer was 3.69M ARB ($677.9K) at 20:48. It came from a very active address (0x4a4aaa01…, 329,639 transactions, ARB balance down 67% to 1.8M) and went to an established wallet holding 58,289 ETH (0xb0a27099…, ARB balance up 65% to 9.4M). Neither address is labeled, and the transfer came about 40 minutes before the drop. E8 E10 E11
0x91d40e48…, a very active address with 2.1M transactions, sent 1.01M ARB ($186.3K) at 21:15 and 509K ARB at 20:48. The 509K ARB was forwarded on to another address at 20:50. Its ARB balance fell 13% to 9.9M. All of these addresses are unlabeled. E8 E12
Known exchange wallets hold 3.7M ARB in total. The Binance wallet holds 102K ARB, down 54.78% in 24h; Gate holds 3.6M ARB, up 3.37%. These balances are small next to the volume traded. E9

Market context

BTC fell 0.55% and ETH 1.09% over the window. Total crypto market cap is down 2.97% in 24h, and ARB is not trending. E14
Funding is at or below normal: Binance 0.0055%, Bybit 0.0100% and OKX 0.0040% per 8h. Binance top-account long/short ratio is 1.83; other positioning data is unavailable. E4 E5
The Fear & Greed index is 55 (Greed), down from 64 a week ago. Arbitrum Bridge TVL is $3.47B, down 0.73% over 1 day and 3.34% over 7 days. E15 E16

What to watch

Whether ARB holds or loses about $0.179, and whether Binance volume stays above roughly 2× normal
Further drops in open interest or a turn in funding to negative, either of which would point to shorts building
Any movement of ARB from the high-activity unlabeled senders (0x4a4aaa01…, 0x91d40e48…) to labeled exchange wallets
ARB vs ETH and BTC, to see whether the underperformance continues
Whether Gate's exchange wallet balance keeps rising

Caveats

The evidence does not identify who sold at 21:31–21:32 or why; there is no news data.
The 'very active' addresses are unlabeled and may be exchange hot wallets or contracts that the entity map does not cover, so the $0 exchange-flow figure may understate exchange activity.
Taker buy/sell and global long/short data were unavailable (null).
The window ends at the drop, so the 15-minute price path does not yet show any follow-through or recovery.
