$ARB Soars 40% in a Week —BUT WHY ??? BECAUSE, Robinhood Rumors, Market Maker Moves, and Whale Rotations Drive the Rally

The price of ARB has surged 40% over the past week, and the buzz isn't just retail hype — it’s a mix of speculation, smart money rotations, and major on-chain shifts.

The rally was largely sparked by rumors that Robinhood might partner with #ARBİTRUM to build a blockchain platform allowing European investors to trade U.S. stocks — a potential game-changer for both ecosystems.

On-chain data backs the momentum:

418.4K active addresses were recorded on #Arbitrum in the last 24 hours, up 25% from the previous week (via DefiLlama).

A multisig wallet, possibly linked to Gelato Network, transferred 20M ARB ($5.39M) to market maker GSR.

Since then, GSR’s trading activity in ARB has increased notably, with 9.48M ARB ($3.1M) sent to Binance in the past 7 days.

Meanwhile, whales and institutions are also making big moves:

Anchorage Digital custody wallets transferred 50.1M $ARB ($15.3M) to Wintermute’s hot wallet over the past two weeks.

A wallet likely tied to Monetalis received 42.19M ARB ($12.88M) in the past week, now holding 77.12M ARB ($27.81M) — making it the 13th largest holder.

But not everyone is holding.

A wallet (0xC4Db...), possibly linked to Paradigm Capital, Teneo, or DeFiance Capital, has deposited 63.27M $ARB ($19.8M) to Bybit, Binance, and OKX since June 14 — signaling that some investors may be selling into strength.

Address: 0xC4Db5dB4c8945c120B0425a68435b2A15852E611

In summary: #ARB 's rise isn't just hype — it’s institutional.

Fueled by partnership speculation and liquidity moves from major market makers and funds, this week’s rally may reflect deeper structural shifts in who holds the chips.
