Cost to Build a Stock Trading App Like Robinhood in 2026

What a Robinhood-style trading app includes

Robinhood made investing feel like a consumer app: open an account on your phone, add money from your bank and place a trade in a few taps. The screens are the easy part. Behind them sit a regulated broker that holds the money and the shares, a market data feed, identity checks, and money movement that must reconcile to the cent every day.

• Investor app: sign-up, identity verification, bank linking, deposits and withdrawals, search, quotes, watchlists, market and limit orders, portfolio, activity, notifications.
• Brokerage layer: account opening, order routing, execution, custody and clearing, all through a brokerage partner's API.
• Records: trade confirmations, monthly statements and tax documents, which most partners generate for you.
• Operations console: customer support, account reviews, transfer issues, audit logs and reports for your partner.

How much does it cost to build an app like Robinhood?

Feature-by-feature cost breakdown (MVP)

Hours include design, development and testing for each component. Costs apply our blended rate of $28 to $38 an hour, and the headline range allows plus or minus 15 percent on hours. Open this setup in the calculator to change it. The four integrations are the brokerage partner, market data, bank linking and identity checks. The fintech line covers the ledger, reconciliation, KYC flows and audit trails, and fintech safeguards add about 20 percent across the build for security reviews and testing of every money-moving path.

MVP vs full product: what gets added

Team and timeline

The MVP suits 3 senior mobile engineers, a designer (part-time), QA and a delivery lead, plus a compliance lead on your side. The build takes 11 to 21 weeks. Partner due diligence, contracts and app review usually set the real launch date, so start them in the first week of discovery. A good order of work: account opening and funding first, then quotes and orders against the partner's sandbox, then statements, the console and a closed beta with real money and small limits.

Recommended technology

Running costs to plan for

• Brokerage partner fees: usually a platform fee plus per-account or per-trade charges. Partners quote these on request.
• Market data licences, which grow with the number of users who see real-time prices.
• Identity checks per new user and bank-linking fees per connected account.
• Security testing, penetration tests and compliance monitoring.
• Hosting with high availability during market hours, and a maintenance retainer of $1.5k to $8k per month.

How Robinhood makes money

Trading is free to customers, so the money comes from around the trade. Robinhood reported total net revenues of $1.42 billion for the third quarter of 2026. Transaction-based revenues were $867 million, led by options ($399 million), event contracts ($173 million), equities ($121 million) and crypto ($120 million). For equities and options this is payment for order flow: fees that market makers pay for routing customer orders to them. Net interest revenues were $415 million, and other revenues of $142 million include Robinhood Gold, a $5 a month subscription with 5.2 million subscribers.

A new app will not have that scale, so plan revenue that works early: a revenue share agreed with your brokerage partner, a paid tier with research and higher cash interest, and fees for advisory or premium features. Your ledger has to track each of these from day one.

Regulation: SEC, FINRA and your brokerage partner

In the US, a firm that handles securities trades for customers is generally a broker-dealer. The SEC's guide says a broker-dealer may not start business until its Form BD registration is granted, it has joined a self-regulatory organisation such as FINRA, it is a member of SIPC, it meets state requirements and its staff hold the required qualifications. That is a long, regulated process, which is why many startups launch through a brokerage-as-a-service partner instead.

• Brokerage partner: Alpaca's Broker API offers fractional stocks, options, crypto and back-office operations, with securities trading through Alpaca Clearing. DriveWealth, a registered broker-dealer and FINRA and SIPC member, offers onboarding, funding, trading, statements and tax reporting by API. Your app is the experience; the partner is the broker of record.
• Identity checks: broker-dealers must run a written customer identification programme with risk-based identity verification, so KYC is part of sign-up from day one.
• Regulation Best Interest: when a broker-dealer recommends a security or strategy to a retail customer, it must act in that customer's best interest. Features that suggest what to buy need compliance review before launch.
• SIPC disclosure: SIPC protects customers of a failed member firm up to $500,000, including a $250,000 limit for cash. Show the partner's disclosures where users fund and trade.
• Your own status: depending on how you earn money and what you recommend, your company may still need its own registration. Take securities counsel advice before you sign with a partner.

How to reduce the cost

1. Launch on a brokerage partner instead of becoming a broker-dealer.
2. Start with US stocks and ETFs only; add options or crypto once you have users and approvals.
3. Use the partner's statements, tax forms and KYC rather than building your own.
4. Show delayed or partner-supplied prices first; pay for real-time data once engagement proves it.
5. Ship one platform first, then add the second once retention is clear.
