Arbitrum (ARB) is on a tear today. The ARB price is up nearly 18%, trading around $0.3602, and the trading volume has exploded, jumping over 490% in just 24 hours. It’s clear traders are paying attention again. On-chain activity is heating up, and social buzz around ARB is picking up fast, all thanks to some big speculation in the air.
Bloomberg reported that Robinhood might be working on a blockchain-based platform that would let European users trade U.S. stocks. What’s interesting is that Arbitrum is one of the top contenders for the tech behind it. Solana is also reportedly being considered, but nothing’s official yet. Neither Robinhood nor the teams behind Arbitrum or Solana have confirmed or denied anything.
Still, the rumor alone has been enough to light a fire under ARB. A tweet doing the rounds suggests Robinhood might actually be building its blockchain stack directly on Arbitrum. That kind of talk tends to drive momentum, and it’s showing in Arbitrum’s price and the spike in volume.

On top of that, there’s buzz around the upcoming Yapyo launch on GU Trade, which will have Arbitrum support baked in. That’s adding more fuel to the fire. With the ecosystem expanding and traders piling in, ARB price surge isn’t just about rumors; it’s riding a real wave of attention across DeFi and Layer-2 circles.
Arbitrum Price Technical Setup Shows Breakout Conditions
ARB broke above a key resistance near $0.345, shifting market structure and initiating a steep rally. The breakout moved past the 50-period simple moving average and extended toward $0.39 before encountering trendline resistance.

Current price action shows some hesitation near this resistance zone. The RSI previously reached overbought levels above 76 and has since cooled to 60.27. Traders may be observing potential divergence before initiating further positions.
The descending trendline around $0.39–$0.40 remains a key resistance area. The Arbitrum Price was rejected on the first test, suggesting this level will need strong volume to break.
On the downside, the $0.345 zone now serves as a support level, followed by the 50 SMA around $0.304. A breakdown below this range would bring the demand zone between $0.26–$0.28 back into view.
