Index · Crypto & Web3 · AI Visibility · Companion to the Stablecoin Citation Share Index 2026. Methodology: 5W AI Communications Citation Index (locked, 40/20/20/15/5) · Dataset: 50 buyer prompts × 5 engines × 3 reads · 750 observations · May 18 – June 7, 2026.
Ask a chatbox where to buy Bitcoin, which exchange is safest, or how to start with crypto, and the answer is a ranked short list — and the same three names show up on top of every engine. Two exchanges own the "safe" frame. A third owns the global frame. The contested ground is everything below the top three.
This is the inaugural Crypto Exchanges Citation Share Index — the first ranked reading of which crypto exchanges the AI engines actually cite. Same locked 5W Citation Index methodology.
Headline finding: Coinbase owns regulated. Kraken owns the experienced-trader frame. Binance owns global. Robinhood owns the gateway buyer — and is treated as a stocks-and-crypto answer, not a crypto-native one.
The Citation Share Leaderboard
| # | Exchange | Focus | Citation Share | Index Score |
|---|---|---|---|---|
| 1 | Coinbase | U.S. regulated | 26.3% | 91.8 |
| 2 | Kraken | U.S. trader-focused | 17.4% | 83.7 |
| 3 | Binance | Global / non-U.S. | 15.8% | 81.9 |
| 4 | Robinhood Crypto | Gateway buyer | 9.7% | 72.4 |
| 5 | Crypto.com | Card + global retail | 8.4% | 68.6 |
| 6 | Gemini | U.S. regulated / Winklevoss | 6.2% | 61.3 |
| 7 | OKX | Global derivatives | 4.8% | 54.7 |
| 8 | Bybit | Derivatives / Dubai | 3.6% | 47.2 |
| 9 | Bitstamp | Europe / institutional | 3.1% | 43.8 |
| 10 | KuCoin | Altcoin-heavy | 2.9% | 40.1 |
Read the gap. Coinbase alone holds 26.3% of citations — the largest single-brand exchange share in the chatbox. The U.S. regulated stack (Coinbase, Kraken, Gemini) holds 49.9% combined. Binance leads outside the U.S. but is described with explicit jurisdiction caveats on most U.S. buyer prompts.
Engine-by-Engine
| Engine | #1 | #2 | #3 | Notable |
|---|---|---|---|---|
| ChatGPT | Coinbase | Kraken | Binance | Strong regulated bias on U.S. prompts |
| Claude | Coinbase | Kraken | Gemini | Most conservative — Gemini in top 3 |
| Gemini | Coinbase | Binance | Robinhood | Robinhood as gateway answer |
| Perplexity | Coinbase | Kraken | Binance | Heavy Reddit-source weighting |
| Google AI Overviews | Coinbase | Kraken | Crypto.com | Sparse outside top 3 |
Coinbase is #1 on every engine. The disagreement is below the top spot — Kraken on four engines, Binance on one, and the Winklevoss-owned Gemini exchange punching above its weight inside Claude (the most regulated-frame engine).
Movers, Risers, and the Long Tail
Climbing: Robinhood Crypto — the gateway-buyer frame is producing strong citation share on "how do I start with crypto" prompts. Robinhood is the answer for someone who already has a Robinhood stock account, which is a large addressable cohort.
At risk: Binance — the regulatory overhang continues to anchor U.S. citations with jurisdiction caveats. Binance.US is a separate entity but engines often conflate them, producing confused answers. KuCoin, Bybit, OKX — described with U.S.-restriction language across four of five engines.
Invisible: Bitfinex, HTX (formerly Huobi), MEXC, Gate.io, BitMart. All receive single-digit citation counts. The chatbox does not surface them on general retail-buyer prompts.
What This Means for Operators
1. Regulated framing is the dominant moat. Coinbase's lead is built on the regulated frame. Kraken sustains its #2 position with the same frame plus the trader-focused product depth. The exchanges that argue against regulation in their marketing get squeezed inside the chatbox.
2. Jurisdiction clarity is a citation surface. Engines reward exchanges that publish clear U.S. vs non-U.S. product distinctions. Binance vs Binance.US confusion costs both entities citation share.
3. Earn the Reddit citation layer. r/CryptoCurrency, r/Bitcoin, and r/ethereum are doing real work — see the Reddit Citation Share Index. Exchanges with strong AMA history and corrected-thread presence in those communities score better.
4. Card and rewards programs leak into the citation layer. Crypto.com's card program is doing work in citation share that the trading product alone would not. Adjacent consumer-product surfaces compound the brand inside the chatbox.
Why is Coinbase so far ahead?
Three factors compound. The regulated framing — public company, SEC-registered, audited — is extracted cleanly by the engines. The brand is consistent across U.S. and international queries. And the third-party citation layer (CoinDesk, Bloomberg, mainstream press, Reddit) refers to Coinbase as the default "safe" U.S. answer more than any other exchange.
Why does Binance lead globally but not in the U.S.?
Engines attach jurisdiction caveats by default. The 2023 settlement and subsequent regulatory framing are durable in the retrieval layer. Binance.US is treated as a separate entity but the confusion between the two costs both citation share on neutral U.S. buyer prompts.
Why is the Winklevoss-owned Gemini exchange in the top six?
The regulated frame works for them. Claude in particular treats Gemini as a top-three answer on safety prompts because the exchange publishes audit and regulatory posture clearly. The brand-naming conflict with Google's Gemini engine produces minor retrieval noise but does not cost meaningful citation share — engines disambiguate by context.
