ETOR vs IBKR: How eToro Group and Interactive Brokers Group Compare (2026)
Last updated August 2026
Short answer
IBKR is the larger of the two ($149.25B market cap): the incumbent the market prices for continued execution (27.57x forward earnings, beta 1.33). ETOR is the smaller challenger ($2.80B), cheaper on forward earnings (10.53x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
ETOR vs IBKR: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | ETOR | IBKR | What it tells you |
|---|---|---|---|
| Market cap | $2.80B | $149.25B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 10.53 | 27.57 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 14.68 | 34.92 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Price vs 52-week range | 31% of range | 75% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 2.15 | 6.68 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: ETOR is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how ETOR and IBKR affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. ETOR and IBKR share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined ETOR and IBKR exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does eToro Group (ETOR) do?
eToro operates a retail investing platform where users trade stocks, ETFs, currencies, commodities and crypto in one account, and where the signature feature is social investing: users can follow other investors, see their portfolios, and mirror their trades automatically through CopyTrader. The business monetises spreads and commissions on that activity, plus interest on client cash and a set of ancillary fees. It came to the public market on 14 May 2025, pricing an upsized IPO at $52.00 per share, raising roughly $620 million and opening at $69.69 on its first day. Since then the platform has kept growing on the metrics management steers by: funded accounts reached roughly 4.07 million in the first quarter of 2026, up about 13% year over year, and assets under administration were around $20.1 billion by May 2026, up roughly 18%.
What does Interactive Brokers Group (IBKR) do?
Interactive Brokers Group operates one of the largest electronic brokerage platforms in the world, offering trading in stocks, options, futures, currencies, bonds, funds, and prediction markets across more than 170 markets from a single unified account. Its edge is automation and cost: the firm runs on lean technology, passes through low commissions and margin rates, and serves a global mix of active individual traders, hedge funds, proprietary trading groups, financial advisors, and introducing brokers. Revenue comes mainly from two engines, transaction commissions and net interest income earned on customer cash balances and margin loans.
ETOR vs IBKR: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- ETOR drivers: Funded accounts and assets under administration; Multi-asset mix as a shock absorber.
- IBKR drivers: Account and client-asset growth; Net interest income on customer balances.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The dominant risk is that revenue is a function of customer activity, not customer count, so a quiet market can compress earnings even while funded accounts keep rising. For IBKR, the biggest swing factor is interest rates, since a large share of profit is net interest income that would compress if rates fall.
ETOR or IBKR: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick ETOR if you believe its drivers more; IBKR if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the ETOR and IBKR guides.
ETOR vs IBKR: the full fundamentals
ETOR. The headline revenue figure is misleading if read literally: eToro books crypto on a gross basis, so the roughly $13.7 billion 2025 line reflects transaction value passing through, while net contribution (roughly $258 million in the first quarter of 2026) is the figure that maps to profits. Judged on net contribution and net income, the company is profitable and growing at a healthy clip. Judged on the share price, the market has been unwilling to pay IPO-day multiples for earnings it views as activity-dependent, and second-quarter 2026 results were scheduled for 11 August 2026.
IBKR. As of July 2026, IBKR trades at roughly 40 times trailing earnings, a premium to its own history after the stock roughly doubled over the prior year. Growth has been strong, with record quarterly revenue and pre-tax margins above 70 percent, but the elevated multiple leaves less room for error if rates fall or trading volumes slow.
Headline figures (approximate, August 2026): ETOR shows market cap ~$2.9B (share price ~$37 vs $52 IPO), revenue (2025, gross crypto basis) ~$13.7B, net contribution (q1 2026) ~$258M, up ~19% YoY, gaap net income (q1 2026) ~$82M, up ~37% YoY; IBKR shows revenue (ttm net revenues) ~$6.5B, q1 2026 net revenues ~$1.67B, net interest income (q1 2026) ~$904M, commissions (q1 2026) ~$613M.
The bottom line: ETOR vs IBKR
ETOR and IBKR are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined ETOR and IBKR exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between ETOR and IBKR?
+
eToro operates a retail investing platform where users trade stocks, ETFs, currencies, commodities and crypto in one account, and where the signature feature is social investing: users can follow other investors, see their portfolios, and mirror their trades automatically through CopyTrader. Interactive Brokers Group operates one of the largest electronic brokerage platforms in the world, offering trading in stocks, options, futures, currencies, bonds, funds, and prediction markets across more than 170 markets from a single unified account. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is ETOR or IBKR the better stock?
+
Neither is universally better. IBKR is the larger incumbent; ETOR is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, ETOR or IBKR?
+
On forward P/E (as of August 2026), ETOR trades at 10.53x and IBKR at 27.57x, so ETOR is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both ETOR and IBKR?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of ETOR vs IBKR?
+
ETOR: The dominant risk is that revenue is a function of customer activity, not customer count, so a quiet market can compress earnings even while funded accounts keep rising. Crypto is the sharpest version of that: it went from roughly 10% to about a quarter of net trading contribution in two years and then cooled in early 2026, and the gross-basis revenue presentation (roughly $13.7 billion for 2025 against a far smaller net contribution) makes the top line look far more stable than the economics beneath it. Regulatory exposure is spread across many jurisdictions, and crypto rules in particular can change the product set eToro is allowed to sell in a given market with little notice. Competition is intense and largely from better-capitalised US incumbents plus zero-commission challengers, which caps pricing power. Finally, the stock has traded well below its $52 IPO price for most of its public life, so the market's willingness to re-rate on good quarters has, so far, been limited. IBKR: The biggest swing factor is interest rates, since a large share of profit is net interest income that would compress if rates fall. Commission revenue depends on trading volumes, which can drop sharply in calm or fearful markets. The company carries counterparty and margin risk if clients or clearing houses fail to meet obligations, and it operates under many regulators across dozens of countries, so rule changes or enforcement actions are an ongoing exposure. The unusual ownership structure, where public shareholders hold a minority interest in the operating partnership, and a premium valuation after a large price run mean the stock can be volatile if growth or margins disappoint.
