What it is
Share is a mobile app built as an official Polymarket partner, downloadable on iOS, that lets a trader sign in with an existing Polymarket account and trade the same positions from a phone rather than a browser. The operator states that funds and volume stay on the trader's Polymarket account rather than moving into a separate Share balance, and the app layers live charts, a portfolio view and wallet tracking on top of the standard Polymarket order book.
Share is built around following other traders: a user browses profiles, watches real time holders and can copy the trades of accounts they follow, with payouts promised on trades copied from them. Since 2026-04-23, the builder has logged 78.8K fills over 145, drawn from a cohort of 125 wallets concentrated lately in tennis.
How it works
A trader connects by signing in with their existing Polymarket account rather than creating a new one for Share; the app authenticates against that account and pulls in the same positions, balances and transaction history the trader already has on Polymarket.com. There is no separate deposit step described beyond that link, and the operator states explicitly that funds and volume stay on the Polymarket account itself.
Once connected, orders placed inside Share route through Polymarket's own CLOB rather than a private matching system, tagged with Share's builder code so the fill gets attributed back to this profile. The app adds a mobile layer on top: live charts that update as markets move, a portfolio screen showing the current value of open positions, and a leaderboard for finding traders to follow or copy. Copy trading works by mirroring another wallet's trades rather than pooling funds with them, and the operator promises a payout to the trader being copied each time someone replicates one of their positions.
Share does not appear to custody funds separately from Polymarket; it reads and writes against the account a trader already controls, so the exposure a trader carries is the same exposure they would carry trading directly on Polymarket, plus whatever access they grant the Share app itself.
What it does
Real time holder alerts
Notifies a trader the moment a wallet they follow opens or exits a position, useful for spotting when a group's conviction changes before they say so.
Wallet watch notifications
Follows any onchain wallet and pushes an alert on every trade it makes, letting a trader react to a specific address rather than a whole market.
One-tap copy trading
Mirrors a followed trader's position directly from their profile, replacing manual order entry with a single action.
Copy trade payouts
Pays the original trader when someone copies their position, turning a public track record into a revenue source.
Live portfolio view
Shows the current value of open positions in real time, so a trader can check exposure without pulling up Polymarket's own site.
Who it is for
- Mobile-first Polymarket traders
- Wants full market access, live charts and portfolio tracking without opening a browser or switching to Polymarket.com.
- Traders who follow specific wallets
- Watches known or notable addresses and gets an alert the instant they open or close a position.
- Traders who copy others' calls
- Mirrors a followed trader's calls directly rather than researching markets independently, accepting the tradeoffs that come with someone else's timing.
- Traders building a public track record
- Uses Share's profile and leaderboard to be visible and collects a payout whenever someone copies a posted call.
- Traders with retail-sized positions
- Fits the app's typical fill size ($129), better suited to frequent smaller bets than large block orders.
What it costs
Share's curated listing states a flat 1%, but neither the operator's product page nor its App Store listing breaks out a trading fee schedule anywhere a prospective user can read before connecting an account; the marketing centers on features and copy trade payouts, not on cost. Polymarket's own per-market trading fee applies the same regardless of which builder routes an order, so it is not something Share controls or discloses separately. A trader should look inside the app itself, at the order entry or confirmation screen, for the actual rate charged on a given trade before routing meaningful size, rather than relying on the headline figure alone.
Strengths
- Signs in with an existing Polymarket account, so a trader keeps the same positions and history instead of migrating to a new balance.
- Adds real time wallet alerts and live charts that push notifications Polymarket's own site does not send.
- Pays copied traders directly, giving an incentive to post calls publicly rather than trade anonymously.
- Runs as a native iOS app, which suits a trader who wants to check markets between other tasks on a phone.
- Carries official Polymarket partner status, so account linking uses Polymarket's own sign-in rather than a third-party credential store.
Limitations
- The operator publishes no itemized fee schedule outside the app itself, leaving the advertised rate as the only figure a trader can check in advance.
- Ships only as an iOS app, so a trader on Android or desktop has no native client to use.
- Depends entirely on the Polymarket account it connects to, so any restriction or issue on that underlying account carries straight through to Share.
- App Store reviews flag missing detail on fees and limit orders, gaps the operator has not closed at the product page level.
Custody and transparency
Share does not hold trader funds separately from Polymarket; a connected account keeps its balance, positions and history on Polymarket itself, so custody risk sits with Polymarket rather than with this app. The tradeoff is operational: granting Share access to a Polymarket account extends the attack surface to a second app and its sign-in flow, and the operator does not publish a fee schedule or a transaction log format beyond what appears inside the app, so a trader relying on Share for record-keeping should still cross-check balances and fills against Polymarket.com directly rather than treating the app's view as the sole source of truth.
Verdict
Share works best as a phone-native front end for an account a trader already runs on Polymarket, adding wallet alerts, charts and copy trading on top rather than replacing the exchange itself. Its case for a mobile trader who wants to follow other wallets, get notified on their moves and mirror calls with one tap is straightforward, and the payout for copied trades gives an active trader on the platform an extra reason to post publicly. A trader who wants a published fee schedule before committing capital, or who needs a desktop or Android client, should look elsewhere; checking #51 on the leaderboard and the scale of 125 before routing meaningful size through it is worthwhile regardless.
