Which Arcus? Arcus Exchange vs Arcus Biosciences, Arcus Network and Other 'Arcus' Results

Arcus

Search for "Arcus" and you get an eye condition, a cancer-drug company, a Pokémon misspelling and a crypto token with nothing to do with the exchange this site covers. ArcusGuide is about Arcus the exchange at arcus.xyz: a decentralized exchange for Stock Tokens and perpetual futures on Robinhood Chain, built by dYdX Labs. If that is what you are after, what is Arcus is the place to start. If it is not, the table below should get you to the right Arcus fast.

Every "Arcus" at a glance

Sources for the table are in each section below. The exchange-related rows were checked on October 1 and 2, 2026.

Arcus, the exchange (arcus.xyz)

This is the Arcus this site covers. It launched on July 1, 2026, lets users in eligible countries trade tokenized US stocks with no Arcus fee, and offers perpetual futures with up to 50x leverage to users with an invite code. It is built by dYdX Labs (dYdX Trading Inc.), and Robinhood Crypto is a strategic investor. It is not available in the US, Canada or the UK.

How to recognize the official Arcus:

• Domains: arcus.xyz and its subdomains, mainly app.arcus.xyz, docs.arcus.xyz, help.arcus.xyz and waitlist.arcus.xyz.
• X account: @arcus_xyz, which is the renamed former @dYdX account. The Arcus and dYdX guide explains the history.
• Data listings: CoinMarketCap lists Arcus as an exchange, and CoinGecko has exchange pages for Arcus spot and Arcus futures. Neither site lists an Arcus governance coin.
• Typo trap: Arcus's own Protocol Terms misprint the docs address as "arcus.docs.xyz." The real address is docs.arcus.xyz. A misspelled domain like that is exactly what phishers register.

Official Arcus tokens that are not "the Arcus token"

Arcus does issue tokens, just not a governance coin. pTokens such as PBTC (BTC 1x long), PBTC3X (BTC 3x long), SBTC and SBTC3X (shorts) and PHOOD3X (HOOD 3x long) are ERC-20 tokens that wrap a leveraged Arcus perp position. Five of them have CoinGecko pages. If a search for "arcus token price" lands you on one of these, you are looking at a leverage product, not a share in Arcus. The pTokens guide explains how they work.

The ARCUS ticker: Arcus Network (unrelated)

On CoinGecko, the symbol ARCUS belongs to Arcus Network, which describes itself as an x402 AI-agent payments project on the Arc chain, with a website at arcusnetwork.co. It has no connection to the Arcus exchange, dYdX or Robinhood. When I checked it on October 2, 2026, it was a micro-cap token with a market value of a few hundred thousand dollars.

Some price aggregators and airdrop blogs have published "Arcus price" or "$ARCUS" pages for the exchange anyway. The exchange's Help Center is unambiguous: "No, Arcus does not currently have a token." The only official hint of a future token is dYdX founder Antonio Juliano's line that "an allocation of any future Arcus token will be reserved for the dYdX community," and no token, ticker or date has been announced. Points do not change that: Arcus's terms say points carry no right to any token or airdrop. The points and airdrop guide covers what is and is not confirmed.

Fake Arcus tokens on Robinhood Chain

This is the one that can cost you money. Because Robinhood Chain is permissionless, anyone can deploy a token called "Arcus" on the same network where the real exchange operates. A DEX Screener search for "arcus" on October 1, 2026 returned several, including:

• 0x904043F5442EcCcf998Fa898FdA4785d2b5F7777 (Robinhood Chain)
• 0x94FFA58c0BC366FEEfDCBD64B5004a9d6475A3C6 (Robinhood Chain)
• 0x6e4db65dB8758D943F61d2F9Abcb26449B93082D, named "Arcus Pons" (Robinhood Chain)

Others exist on Base, Arc and Solana. None are official. Robinhood Chain has also seen wider token scams, including a rug-pull ring tied to 53 token launches (The Cryptonomist), so a token showing up on that chain proves nothing about who made it.

Fake websites follow the same pattern. MetaMask's phishing blocklist now includes dozens of Arcus-themed domains: fake waitlists, fake "TGE" claim pages, fake points pages and fake bridges, with names like waitlist-arcus.xyz, tge-arcus.xyz, arcus-app.xyz and dydx-arcus.com. The full list and a checklist for vetting links are in Arcus scams and fake sites. Note that genesis.arcusfoundation.xyz is a phishing domain; it has nothing to do with the real Arcus Foundation charity either.

Arcus Biosciences (RCUS)

If you searched "arcus stock," "arcus earnings" or "arcus stock price," you probably meant Arcus Biosciences, an oncology biotech company in Hayward, California, listed on the NYSE as RCUS. Its filings are on SEC EDGAR. It is unrelated to the exchange. One possible point of confusion: the Arcus exchange lists tokenized versions of US stocks, but RCUS was not among the 242 tokens on Arcus's spot router or its perp markets on October 2, 2026.

Arcus senilis and other medical terms

The single most common "arcus" search is medical. Arcus senilis (or corneal arcus, and arcus juvenilis in younger people) is a gray or white ring around the edge of the cornea, often linked to cholesterol deposits (Wikipedia). Anatomy has others, like the arcus tendineus. If that is what brought you here, a doctor or an ophthalmology source is the right next stop.

Arceus, Marcus and Argus

Search engines also mash "Arcus" together with similar names:

• Arceus is a Pokémon, and misspellings drive many "arcus vs" and "is arcus" searches.
• Marcus by Goldman Sachs is a consumer bank, so "arcus referral code" sometimes autocorrects to "marcus referral code."
• Argus shows up as a fuzzy match for several queries.

None of these relate to the exchange.

"Arcus login" and "Arcus app"

Two other products compete for these searches:

• Arcus Air, now the IQVIA Hospital Information System, is hospital software with its own login page (IQVIA).
• Arcus Apparel Group in Houston and a weather app named Arcus also appear for "arcus app."

The Arcus exchange's app lives at app.arcus.xyz. Its iOS app, Arcus Mobile, is listed on the App Store as a pre-order (seller Pocket Protector Labs Inc.), and an Android listing exists under the package name xyz.arcus.app. Anything else claiming to be the Arcus trading app deserves suspicion.

Arcus referral: the trading program vs the hiring bonus

"Arcus referral" has two official meanings, both from the same company:

• The trading referral program. You join with someone's code, Arcus takes 5% off your trading fees, and the referrer earns a share of your fees. Our code is ARCUSGUIDE, and ArcusGuide earns a share of fees from referred traders. The referral code guide explains how it works and why a referral link is not a perps invite code.
• The employee referral program. The "$15,000 referral bonus" on the Arcus careers page is for referring job candidates, under separate terms. It has nothing to do with trading.

The rest of the Arcus crowd

A handful of other organizations share the name and occasionally surface in finance searches:

• Arcus Foundation: a philanthropy focused on LGBTQ rights and great apes (arcusfoundation.org).
• Arcus FI / Arcus Pay Network: a bill-pay fintech that Mastercard bought in November 2021 (Finextra).
• Arcus Infrastructure Partners: a European infrastructure fund manager in London.
• Arcus ASA: a Nordic spirits group, now Anora Group, delisted from the Oslo exchange in 2021.
• Arcus Investment: a Japan-focused equity fund manager.
• Arcus cloud: a low, horizontal cloud formation (Wikipedia).

None of them are connected to arcus.xyz.

Getting to the real Arcus safely

Type arcus.xyz yourself or use a bookmark rather than clicking search ads or links in replies. Arcus's affiliate terms ban affiliates from buying search ads on Arcus brand keywords, so treat a search ad for "Arcus" with suspicion. Once you are on the right site, how to trade on Arcus walks you through your first trade, and what is Robinhood Chain explains the network underneath.
