berry

Berry is a mobile investing app from Berry Tech Inc., available on iOS and Android, that lets people trade stocks, ETFs, crypto and Polymarket prediction markets from one account. Securities trade over Alpaca Securities LLC's brokerage infrastructure, which is how the app can advertise fractional entry and zero-commission stock trades. On Polymarket its verified profile sits at #135 by attributed volume, having routed $1.1M since the index first picked up its order flow.

The prediction market side is handled differently: Berry's own disclosures state that crypto and prediction market services run through regulated third-party partners rather than Alpaca, separating that activity from the brokerage account traders use for stocks. That split matters more than the marketing copy about accessible investing, because it is the third-party arrangement, not Alpaca's brokerage protections, that governs what happens to money routed into Polymarket markets.

A trader opens a Berry account on the iOS or Android app, funds it via the same deposit flow used for stocks and ETFs, and from there taps into prediction markets alongside the rest of their portfolio. There's no separate wallet connection step described in the app's own materials; the interface bundles prediction market trading into the same account traders use for equities.

Where the order goes: Berry states plainly that crypto and prediction market activity runs through regulated third-party partners rather than Alpaca Securities, the broker that clears its stock trades. Polymarket itself confirms Berry's builder profile, and the attributed order flow reaching $1.1M in total volume and 0 fills gets tagged to Berry's code when it lands on the CLOB, which is how the platform's leaderboard and this page can measure it separately from other builders.

What it holds: Berry's securities protections, the SIPC-style coverage and Alpaca custody it advertises, apply to the brokerage account, not stated to extend to crypto or prediction market positions. Beyond noting two-factor authentication and encrypted data in the app description, the operator does not detail whether Polymarket positions or related balances sit with Berry, the third-party partner, or an on-chain wallet under the trader's control.

• Unified portfolio view

  Tracks stocks, ETFs, crypto and prediction market positions in one real-time portfolio screen instead of a separate Polymarket-only view.

• Automatic deposit scheduling

  Lets traders set recurring deposits so prediction market and stock positions get funded on a schedule rather than through manual transfers each time.

• Two-factor login

  Adds two-factor authentication and data encryption on top of the account password, which matters given the app has no published fee or custody schedule for prediction markets.

• Built-in investing lessons

  Interactive financial education content sits inside the app, aimed at people learning to size positions rather than at experienced Polymarket traders.

Existing Berry stock investors

Already holding stocks or crypto in Berry, these traders can add Polymarket positions without opening a new account or wallet elsewhere.

Traders without a local bank account

The app markets itself to people investing in US assets without a bank account, so Polymarket access through the same app fits that same audience.

Small, dollar-sized position traders

Berry advertises fractional, low-minimum investing, which suits traders sizing prediction market positions well below what a brokerage-style minimum would allow.

Traders wanting one combined app

People who would rather track stocks, ETFs, crypto and prediction markets in a single portfolio screen instead of switching between separate tools.

Berry does not publish a fee schedule specific to Polymarket trading. The Alpaca-brokered stock side advertises zero-commission trades, but the app's own disclosures route crypto and prediction market activity through separate third-party partners, and nothing in Berry's public materials states what those partners charge or how a spread might be built into pricing. A trader sizing a position has no advertised number to check it against, only the attributed volume and fill activity the index tracks, $1.1M and 0 respectively. Anyone routing meaningful size through Berry should ask the app directly what a Polymarket trade costs before assuming the zero-commission stock pitch applies to prediction markets too.

• Fractional, low-minimum investing means a trader can enter Polymarket positions without committing a brokerage-sized amount up front.
• Stocks, ETFs, crypto and prediction markets sit in one portfolio view, useful for traders who already bank their other assets with Berry.
• Two-factor authentication and encrypted data give the account itself more protection than a password alone.
• The stock and ETF side of the app clears through Alpaca Securities, a named, regulated broker, which is more transparent than an anonymous custodian.
• Built-in financial education content helps newer investors size positions before they route money into prediction markets.

• Berry publishes no fee schedule for prediction market or crypto trading, so a trader cannot compare its cost to any other builder before routing an order.
• Its own disclosures state that crypto and prediction market services run through third-party partners rather than Alpaca, so the SIPC-style protection Berry advertises for stocks does not describe what happens to Polymarket positions.
• Recent attributed volume and fills have gone quiet, with $0, $0 and 0 all reflecting no fresh activity through 2026-09-14.
• The app's App Store and Play Store descriptions barely mention prediction markets at all, so most of what Berry documents publicly is about stock and ETF investing, not Polymarket trading.
• A user review on the App Store describes Berry's referral and bonus terms as misleading, a reputational flag for an app that also handles trading money.

Custody splits by asset class: Berry's stock and ETF holdings sit with Alpaca Securities, which carries SIPC-style protection, but Berry's own disclosures state that crypto and prediction market activity runs through separate regulated partners rather than Alpaca, and the app does not say whether that arrangement extends the same protection to Polymarket positions. Berry does not publish a fee schedule or custody terms specific to prediction market trading, leaving traders to rely on the app's general security claims, two-factor authentication and encrypted data, rather than anything documented for Polymarket specifically. Attributed volume and fills have gone flat through 2026-09-14, worth watching before committing new money.

Berry works best as a side door into Polymarket for someone already using the app to invest in stocks, ETFs or crypto, not as a dedicated prediction market terminal. Its Polymarket order flow sits at #135 on the attributed-volume leaderboard with $1.1M routed in total, and the operator has not published pricing specific to prediction markets, so a trader has to accept that uncertainty going in. Someone who wants a single account for all their retail investing may find that acceptable. A trader who wants dedicated Polymarket tooling, published fees or evidence of steady recent flow should look elsewhere first.
