Co-Invest is an AI trading app from Liquid that drops a real brokerage account inside ChatGPT and Claude. You research markets, size positions, and place trades by chatting, then tap Confirm. It is free to use, covers 500+ markets across crypto, stocks, forex, and pre-IPO, and best suits hands-on retail traders who already live in an AI assistant. Rating: 7.1/10.

What is Co-Invest?

We found Co-Invest while digging through the late-May Product Hunt launches, and it is one of the more genuinely novel things we have seen in 2026. It is a trading account that lives inside ChatGPT and Claude. You do not open a separate app or log into a broker dashboard. You talk to the assistant you already use, ask it about a market, and it can pull live data, size a position against your balance, and route the order to a real exchange. Nothing executes until you tap Confirm.

It is built by Liquid, an AI-native trading company founded by Franklyn Wang, a former Two Sigma AI scientist. Liquid raised an $18 million Series Seed extension in April 2026, taking total funding to roughly $25.6 million, and shipped Co-Invest on May 26, 2026. So this is not a weekend hack. There is real money and a real team behind it, which matters a lot when the product is literally moving your money around. Co-Invest is available across all 50 US states and most other jurisdictions, with the usual sanctions exclusions.

The timing is not an accident. 2026 has been the year conversational AI turned into a distribution channel for financial services. Interactive Brokers wired Claude into live trading and portfolio management. Visa, Stripe, AWS, and Coinbase all shipped AI-compatible payment and trading tools. Co-Invest is Liquid’s bet that a lot of people would rather ask an assistant “what should I do with this position” than learn a broker’s order ticket. Whether that is a good idea for your wallet is a separate question, but the direction of travel is clearly real, and Liquid is early to it.

What are Co-Invest’s key features?

Trading inside ChatGPT and Claude

This is the whole pitch. Co-Invest installs as an app inside ChatGPT and Claude, so your trading account and your AI assistant are the same surface. You can say something like “show me BTC funding rates” or “build me a $2,000 position split across SOL and gold,” and the assistant does the work in the chat. The order still needs your explicit confirmation. The assistant can read your portfolio and suggest trades, but it cannot send an order, change settings, or move money on its own.

Market research with sources

Every suggestion comes with a named catalyst and a source link. The assistant surfaces positioning data, funding rates, on-chain wallet activity, order flow, and macro news summaries. This is the part we liked most. Most retail trading apps give you a chart and a buy button. Co-Invest at least forces a reason to exist next to the trade, which is a healthier way to think about risk even if you ignore half of it.

500+ markets in one account

Co-Invest covers more than 500 markets. That includes 200+ crypto perpetuals like BTC, ETH, and SOL, US stocks, commodities such as gold and oil, major forex pairs, Polymarket prediction positions, and pre-IPO secondaries. Getting equities, crypto perps, and prediction markets in a single account is rare. Most people juggle Robinhood, a crypto exchange, and a separate prediction market site. Co-Invest collapses that into one chat.

Paper trading and self-custody

You can test strategies with simulated balances against live market data before risking real cash. And your funds sit in your own wallet, not on a Liquid server. You fund the account by card, on-chain transfer, or an external wallet, and you set stop-loss and take-profit levels inside the chat. The self-custody piece is a meaningful trust signal for the crypto-native crowd.

We want to be clear about the guardrails because they are the difference between this being clever and being reckless. The assistant proposes, you dispose. It can read your balance and your open positions, it can draft a trade with a size and a stop, but it physically cannot push the order through, move money out, or change your account settings without you tapping Confirm. Paper trading sits one layer below that, so you can run an entire strategy on simulated money for a week and see how the AI’s suggestions would have played out before a single real dollar is at stake. For a new product handling real funds, that two-step design is the right default.

How much does Co-Invest cost?

Co-Invest itself is free. There is no subscription and no AI surcharge for using the assistant. You pay the standard Liquid trading fees when you actually execute, plus the usual funding rates if you hold perpetual contracts overnight. Liquid describes its execution fees as generally lower than Coinbase or Robinhood on the same products, which tracks with what we would expect from a newer platform trying to win active traders.

Compare that to the alternatives. Robinhood is free to trade stocks but makes money on payment for order flow and charges spreads on crypto. Coinbase is notorious for fat retail fees. A subscription research tool like a TradingView paid plan runs $15 to $60 per month before you have placed a single trade. Co-Invest charges you nothing to think and only bills on execution, which is the right model for a tool you might open ten times before you actually trade.

One honest note on cost: with perpetual contracts, the fee you pay per trade is rarely the expensive part. Funding rates on perps can quietly eat returns if you hold leveraged positions for days, and that is true on any platform, not just Liquid. Co-Invest surfaces those funding rates in the chat, which is more transparency than most retail apps bother with, but the responsibility to actually read them is still yours. The free app does not make leverage cheap. It just makes the math easier to see.

Who is Co-Invest best for?

Use Co-Invest if you are an active retail trader who already spends real time in ChatGPT or Claude and you want research, sizing, and execution in one place. It is a strong fit for crypto-native traders who want perps, equities, and prediction markets under one roof, and for founders or operators who manage their own money and want faster analysis without flipping between five tabs.

It is also a useful research surface even if you are skeptical about trading through a chatbot. Asking Claude to summarize funding rates, on-chain flows, and the catalyst behind a move, with source links attached, is genuinely faster than opening five tabs. Some people will use Co-Invest mostly as a research and sizing assistant and place the actual trades elsewhere. That is a perfectly valid way to get value out of it.

Skip Co-Invest if you are a buy-and-hold index investor. You do not need an AI assistant to dollar-cost-average into an ETF, and a low-fee broker like Fidelity or Vanguard will serve you better. Also skip it if AI-suggested trades make you nervous. The confirm step protects you from runaway automation, but the friction of conversational trading can still nudge people to trade more than they should. If you lack the discipline, this product will happily let you churn.

Best Co-Invest alternatives

Interactive Brokers: The serious trader’s broker, now with its own Claude integration for portfolio analysis. Far deeper market access and institutional-grade execution, but the interface is famously clunky and there is no conversational sizing baked in. Free to open, commissions vary by asset.

Robinhood: The default for US retail. Cleaner mobile app, commission-free stock trades, and a huge user base. But it is a closed app with no AI assistant layer and weaker crypto and derivatives coverage. Free to trade.

Public: A social investing app with stocks, crypto, bonds, and an AI research assistant called Alpha. Good middle ground if you want some AI research but prefer a traditional app over trading inside a chatbot. Free, with an optional premium tier around $10 per month.

Final verdict: Is Co-Invest worth it?

Co-Invest is one of the few 2026 AI launches that actually changes a workflow instead of bolting a chatbot onto an existing one. Putting research, sizing, and execution inside ChatGPT and Claude is a real idea, the self-custody and confirm-to-trade design is sensible, and the team has the funding and pedigree to keep building. For an active trader who already lives in an AI assistant, it is worth setting up a paper account today.

The caveats are real, though. It launched in May 2026, so it is young, and a young product that touches your money deserves a small starting balance until you trust it. Conversational trading also lowers the friction to trade, which cuts both ways. We are giving it 7 out of 10: a genuinely clever product with a strong team, marked down only for its newness and the discipline it quietly demands from you. Start with paper trading, then size up slowly.
