Who Actually Owns the "Best Broker" Review Sites You're Reading in 2026

Here's a thought experiment. Open a clean browser, search "best stock broker 2026," and count how many of the top ten results share a parent company. If you do the work — we did — the answer is most of them. Bankrate, Investopedia, StockBrokers.com, ForexBrokers.com, investor.com, The Points Guy, CreditCards.com, NerdWallet, Forbes Advisor, Motley Fool. Ten brands, four owners, one business model: get you to open an account so they collect a commission.

This isn't a conspiracy. It's a public, boring, perfectly legal arrangement that hides in plain sight because nobody's incentivized to mention it. Not the review sites (conflict of interest would be on every page). Not the brokers (they pay the sites). Not Google (the ranking system rewards exactly this kind of content). Certainly not the reader, who wants a quick answer to "which broker should I open?"

So: who actually owns what? Here's the 2026 map.

The four companies that own most of the "independent" broker review web

What's actually happening under the hood

The business model across all of these is identical, and it's simple enough to fit on a napkin. A reader types "best online broker" into Google. The review site's article ranks in the top three. The reader clicks through to a comparison table, picks a broker, and clicks "Open Account." That outbound link is tagged with the review site's affiliate ID. The broker pays the review site somewhere between $50 and $500 for each funded account — more for customers who make their first trade, more still for customers who deposit above a threshold.

This is standard affiliate marketing, and it's been a normal part of the internet for 25 years. The problem isn't that it exists. The problem is what happens to rankings when the commission numbers are very different from one broker to the next.

Here's a concrete illustration. A broker running a $50 signup bonus per funded account on affiliate networks is going to generate different ranking behavior from a broker offering $200 per funded account plus a percentage of first-year deposits. Any human editor, no matter how well-intentioned, sees those numbers in the back-office dashboard. The bias doesn't have to be conscious or corrupt to show up in the final ranking — it just has to be structural.

Some of the owners we listed do disclose this. NerdWallet has a standing notice: "We may receive compensation from our partners for placement of their products or services." Investopedia has similar language. Bankrate has layered disclosures. These are technically compliant with FTC guidance. They are also the kind of notices that 99% of readers skim past or don't process.

The four-company concentration in one table

Three private media conglomerates and one public one. Eleven sites. One business model. And these are just the English-language US-facing properties — Reink alone runs UK and international siblings of the same brand.

What a reader can actually do about this

The honest answer is: not much, alone. The consolidation has already happened. The SEO moat is already built. The next "best broker" article you read on Google is statistically likely to be owned by one of the four companies above, because those companies invested tens of millions of dollars in ranking exactly on that query.

What a reader can do is ask different questions.

1. Read the "About" page before the comparison table

Every site on this list discloses its parent. Most bury it. A 20-second check answers the question of what you're actually reading.

2. Check multiple sites, then check the primary sources

The broker's own fee schedule, disclosure documents, and FINRA BrokerCheck profile are published. They are also, admittedly, much drier than a comparison table. But a five-minute skim of a broker's "Fee Schedule" PDF catches things most review sites gloss over — inactivity fees, wire transfer fees, margin rate tiers that only apply above specific balances.

3. Watch for commission disclosure on specific recommendations

FTC guidance requires "clear and conspicuous" disclosure when content is compensated. "Clear and conspicuous" is a judgment call. If the disclosure is in a footer, under a "How We Make Money" dropdown, or next to a 3-point asterisk, it exists but it's not doing real informational work.

4. Prefer sources with different incentive structures

Academic research on brokers (NBER working papers, SEC comment letters, FINRA's own Office of the Investor Advocate) has zero affiliate incentive. It's also harder to read. The trade-off is real. A reader who spends 20 minutes with FINRA's investor education materials learns more than one who reads five review sites, though less entertainingly.

Our own cards on the table

SideBySide runs affiliate links too. We'd be lying if we pretended otherwise. The difference we try to maintain is structural: we rank by data (margin rates, fee schedules, account minimums, bonus terms) rather than by commission tier, and we explicitly feature non-affiliate options — brokers we don't earn from — when they're the right answer for a reader.

On our broker comparison page, only two of the fifteen featured brokers are monetized. The rest are included because excluding them would be editorially dishonest. Public.com gets a "lowest margin" callout despite paying nothing. Fidelity is featured despite having no affiliate program at all. Interactive Brokers is included despite a referral structure that barely pays.

This isn't a flex. It's the only way an affiliate-monetized review site can be honest with itself about the gap between "here's what I recommend" and "here's what earns the commission." The gap is real. The way to bridge it is to rank the things the way you'd rank them for a family member who asked.
