Fidelity vs Cash App Investing: Which Broker Wins in 2026?

Regulation & Safety

Regulatory strength is one of the biggest differentiators in this comparison. Fidelity is overseen by both the SEC and CFTC, giving it coverage across securities and derivatives-adjacent oversight, which matters for investors who may eventually branch into broader asset classes.

Cash App Investing is regulated by the SEC and FINRA, which is a legitimate and respected framework for a U.S. brokerage, but it lacks the additional CFTC layer that Fidelity carries. In our scoring system, this translated into Fidelity earning a full 3/3 on regulatory strength, while Cash App Investing scored 0/3.

For investors who prioritize long-term custody of larger portfolios, Fidelity's deeper regulatory footprint and century-spanning institutional track record (founded in 1946) offer additional peace of mind that a newer, mobile-first platform like Cash App Investing (launched 2019) simply hasn't had time to build.

Account Costs & Minimum Deposit

Neither broker charges a commission on standard trades, and both advertise spreads from 0 pips, so headline trading costs are effectively a wash on paper. The real differentiator is account accessibility.

Fidelity requires no minimum deposit at all, meaning new investors can open an account and start with whatever amount suits their budget. Cash App Investing requires a nominal $1 minimum, which is still extremely low, but technically higher than Fidelity's $0 threshold.

Both brokers also waive deposit and withdrawal fees entirely, which is a strong point for cost-conscious traders on either platform. Where Fidelity pulls further ahead is in the breadth of account types and research tools bundled in at no extra cost, which Cash App Investing does not match.

Trading Platforms & Tools

Fidelity offers both a proprietary web platform and a proprietary mobile app, giving traders flexibility to manage portfolios from a desktop browser or on the go. This dual-platform approach caters to investors who want full charting and research capability as well as mobile convenience.

Cash App Investing, true to its roots as a peer-to-peer payments app, offers only a proprietary mobile platform. There's no desktop or web-based trading terminal, which may limit more active or analytically-driven investors.

If you value robust order types, in-depth research, and the ability to trade comfortably from a larger screen, Fidelity's platform ecosystem is noticeably more complete.

Market Access & Leverage

Fidelity provides access to stocks, indices, and commodities, with leverage available up to 1:2. This gives investors a moderately diversified set of asset classes beyond plain equities.

Cash App Investing focuses on stocks, ETFs, and crypto, with leverage capped at 1:1 (effectively no leverage). This makes it a cash-account-style experience geared toward straightforward, low-risk investing rather than leveraged trading.

The right choice here really depends on investor intent: those wanting crypto exposure alongside stocks may lean toward Cash App Investing, while those wanting commodities and indices exposure with some leverage flexibility will prefer Fidelity.

Company Background & Reputation

Fidelity was founded in 1946 and is headquartered in Boston, USA, making it one of the most established names in the brokerage industry with decades of operating history through multiple market cycles.

Cash App Investing, by contrast, was founded in 2019 and is headquartered in San Francisco, USA. It's a much younger entrant, built as an investing feature within the broader Cash App consumer finance ecosystem.

Longevity isn't everything, but Fidelity's 80-year operating history gives it a demonstrated resilience that newer platforms haven't yet had the chance to prove.

Our Verdict

Taking all factors together, Fidelity earns our award for Best Overall, Best for Beginners, Best for Low Fees, and Best for Regulation in this matchup. Its combination of zero minimum deposit, dual-platform access, stronger regulatory coverage, and broader market selection make it the more complete package.

Cash App Investing isn't a bad broker by any means — its $1 minimum deposit and streamlined mobile app make it approachable for casual investors who already use Cash App for everyday payments. But for traders seeking a more serious, full-featured investing experience, Fidelity is the stronger choice.
