MicroStrategy's token alone holds 16.6% of xStocks' $172.8m book on X Layer
Backed Finance's X Layer market cap grew 187.2% in a month to $172.8m across more than 900 tokenized US equities and ETFs. The largest single line is about $28.6m of that, and it comes with price exposure and no vote.

What happened
- Tokenized stocks issued by xStocks on OKX's X Layer reached a market cap of $172.8 million, a rise of 187.2% in a single month, according to Cryptobriefing.
- The marketplace, built by Backed Finance, now lists more than 900 tokenized US equities and ETFs on the chain, weighted roughly 88% equities and 12% ETFs.
- Each token is backed 1:1 by the underlying security in regulated custody and is a tracker certificate giving economic exposure without legal ownership rights such as voting.
- MicroStrategy's tokenized counterpart MSTRx is near the top of the book at approximately $28.6 million of market cap, with Circle's CRCLx also prominent.

Why it matters
- contradiction The diversification claim and the largest position cannot both be read as stated for X Layer: 16.6% is about 1.8 times a ceiling described as roughly 9%, so either the cap is measured across all chains or this chain has outgrown it.
- exposure A holder's claim runs through Backed Finance's issuance and custody, so the position carries the issuer's solvency alongside the stock's price.
- constraint The $28.6m of MicroStrategy exposure in MSTRx comes without voting rights, and so does every other line in the book.
- capability These certificates can be priced during the 135.5 hours a week the US market is shut, giving 5.2 times as much trading time as the 32.5-hour cash session.
$172.8m divided by 2.872 puts the X Layer book near $60.2m a month ago, so about $112.6m of certificates were created in thirty days [1][1].
MSTRx, the tokenized counterpart of MicroStrategy, is roughly $28.6m of the total, or 16.6% of the X Layer market cap [8][2]. The same account describes diversification guardrails under which no single asset exceeds about 9% of the total portfolio [7]. Those figures do not sit together: 16.6% is about 1.8 times the stated ceiling [3]. Two readings are available. The 9% may be measured across the whole xStocks platform, which now runs on several blockchains [11], in which case X Layer is simply the chain where the MicroStrategy token has pooled. Or the ceiling is a design intention that one month of growth has run past. Cryptobriefing's account states both numbers without reconciling them.
Spread the rest of the book and it thins quickly. $172.8m across more than 900 tickers averages about $192,000 a listing, and with MSTRx removed the remaining 899 average roughly $160,000 each [4][5]. A line that size cannot absorb an institutional order, so whatever depth exists sits in a handful of names.
The platform-wide volume figure is larger and measures something else. Cryptobriefing puts cumulative trading across xStocks at $35bn to $40bn over roughly 800 assets since the June 30, 2025 launch [11], and $35bn is about 203 times the current X Layer market cap [6]. One number is cumulative and multi-chain, the other is single-chain and instantaneous, so the ratio does not say which chain the turnover happened on.
What a holder actually has is a tracker certificate, backed 1:1 by the underlying security in regulated custody, issued by Swiss-regulated Backed Finance, which is associated with Payward, Kraken's parent [6][12][13]. It is not a share. It conveys price exposure and no shareholder rights, and the 1:1 model works only while the custodial and issuance infrastructure stays solvent and transparent [14]. A buyer of MSTRx is therefore taking MicroStrategy's price and Backed Finance's operational soundness in the same line item.
In a catalogue of more than 900 US equities and ETFs, the biggest position is MicroStrategy's token and Circle's is also near the top [8], which are the two names most closely tied to crypto itself. In my view that makes this a crypto venue with equities inside it, and the 187.2% month describes crypto flows more than it describes brokerage customers migrating on-chain. Trading happens through the OKX Wallet, which the publisher describes as low cost and open continuously [9].
What to watch
- Whether MSTRx's share of the X Layer book falls toward 9% as new certificates are minted, or the concentration holds.
- Any per-asset volume or spread disclosure for X Layer, which would show whether listings outside the top few trade at size.
- A regulator acting on tokenized securities in a way that reaches Swiss-issued tracker certificates sold through OKX.
