What they are

Interactive Brokers (IBKR) is the institutional-grade retail brokerage — the platform serious retail and small-professional traders graduate to for global market access, lowest margin rates in the industry, and deep instrument coverage (stocks, options, futures, forex, bonds, funds, crypto in some jurisdictions, 150+ markets in 33 countries).

Public, founded 1977 by Thomas Peterffy. Quant/market-maker DNA still visible.

Positioning (what they say about themselves)

• "The Professional's Gateway to the World's Markets."
• Direct-market access, sophisticated order routing, IB SmartRouting.
• Lowest margin rates (benchmark + ~1.5% blended, material versus 8-12% at Robinhood/Schwab).
• Two commission models: IBKR Lite (retail, commission-free US stocks, PFOF revenue) and IBKR Pro (professional, low per-contract fees, no PFOF).

IBKR Lite - US stocks & ETFs: $0 commission - Options: $0.65/contract (flat) - No subscription - PFOF enabled

IBKR Pro - Fixed: $0.65/contract options, $0.005/share stocks (min $1/order, max 1% trade value) - Tiered: $0.15–$0.65/contract options sliding with monthly volume (<10k = $0.65; 10k-50k = $0.50; 50k-100k = $0.25; >100k = $0.15) - No PFOF - Market-data: $4.50-$15/mo per bundle (US Equity, US Options, OPRA)

No SaaS subscription tier. Revenue is commissions + margin interest + market-data.

How Raxx differentiates (the one-paragraph answer)

IBKR is the best execution venue in retail and has no opinion about what trade to place; Raxx is the opinion layer and has no opinion about where to execute. Those are complementary, not competitive. IBKR assumes you arrive knowing the trade — they fill it cleanly, cheaply, across 33 countries. Raxx assumes you arrive with a P/L goal ("$1k/week premium, $3k max loss on SPX") and hands you three structures qualified on paper. The pitch to an IBKR power user: "Keep IBKR for execution. Use Raxx to decide what to execute." We also solve the UX problem IBKR has never solved — TWS is a 1990s-roots Java app with a legendary learning curve; Raxx is passkey-only, modern, one-persona-optimized, and deliberately the anti-TWS.

What they do well

• Breadth. Nobody in retail matches IBKR's instrument + geographic coverage.
• Execution quality. IB SmartRouting consistently rated best at fill-vs-NBBO.
• Margin rates. For a $100k+ book with regular margin usage, real annual savings.
• API depth. TWS API and IB Gateway are battle-tested, well-documented, support essentially any programmatic retail strategy.
• Stability. Peterffy built to survive; counterparty risk is minimal.

Where Raxx has room

1. UX is famously hostile. TWS is 1990s-roots Java. Cottage industry of "IBKR for beginners" courses.
2. No AI / no proposal engine. IBKR assumes you know the trade.
3. No opinionated options workflow. TWS supports every structure via 400 knobs; no "propose 2-3 structures to my weekly target" flow.
4. No paper-trade retention as first-class feature. Paper account exists; not strategy-level audit-traced.
5. Market-data is a la carte. Running IBKR at home means assembling $4.50-$15/mo subscriptions. Raxx folds reasonable options-data into Pro.

Where they have room (honest)

• Execution cost. IBKR Pro Tiered at volume is cheaper per contract than anything we could negotiate. We don't compete here.
• Margin rates. A trader whose edge depends on cheap margin should use IBKR, full stop.
• Regulatory comfort. IBKR since 1977. We are a startup. For the same fund balance, counterparty trust is not comparable — which is exactly why our broker-agnostic story is the right answer. We don't hold their money.

Implications for positioning

• Integrate with IBKR as a broker target (Pro or Pro+). Single integration that most unlocks the "serious retail options trader" persona.
• Position as "the research layer for your IBKR account." Never "replace IBKR."
• Lean into UX as differentiation. "Keep the broker with the best margin rates in the industry. Stop spending your Sunday in TWS."

Watch-list signals

• IBKR launching their own AI/proposal layer. Unlikely (they don't do feature-layer UX well), but a quant-startup acquisition would narrow the wedge.
• Changes to IBKR Lite PFOF policy (SEC PFOF scrutiny ongoing).
• Margin-rate shifts tied to Fed policy — rising rates widen IBKR's edge and make "bring your own broker" pitch more valuable.
