Perpetual futures linked to traditional-market assets made up 37% of Binance’s perp volume in August.
In one recent 24-hour snapshot they took 10 of the 15 highest-volume contracts on the venue, withSNDK ranking ahead of BTC-USDT, per Binance Research.
Exposure to US-listed companies is now a meaningful share of what a crypto exchange trades. None of it came off an exchange floor.
The objection, stated properly
The zero-sum reading of on-chain equities actually makes sense, and pieces that dismiss it usually dismiss a weaker version. Liquidity is rivalrous. Fragmentation carries a real cost. Every venue that has promised to expand a market has also been accused of splitting one, and incumbent operators say so on the record. Nasdaq President Tal Cohen has cautioned that expanded hours could bring lower liquidity and higher volatility along with increased transaction costs.
The venues on the other side of that argument do not dispute the premise. “Extending market hours is the operational part; creating durable liquidity during those hours is the structural challenge,” says Shunyet Jan, Head of Exchange & Trading at Binance. “Global participants, especially those active as New York closes, are a natural source of that liquidity. That maps closely to our user base, with strong participation from emerging markets and nearly half of our tokenized-stock volume occurring outside U.S. trading hours. By connecting demand from geographies and time zones that traditional sessions have not fully served, we can broaden access to U.S.-linked assets and support a deeper, more global liquidity base.”
So the question is not whether the objection is reasonable. It is whether it holds, and that turns out to be measurable. Trades carry timestamps and participants carry geography. Volume cannibalizing an exchange would show up in the same hours, in the same places.
“We’ve seen across different markets that once the framework is clear,” Jan says, “institutions have more confidence to participate and build.”
Confidence arriving as new accounts in markets an incumbent never served is a different economic event from confidence moving an account between venues. Separating the two means looking at when the trading happens, and the American market has permitted off-hours trading for decades. Fully 80.7% of the calendar week already falls outside regular US equity hours.
There is very little overnight volume to take
That window captured just 10.8% of US share volume in July 2026. The regular session held 89.2%.
The existing overnight venue is smaller again. NYSE research puts current overnight alternative trading system activity below 0.11% of total US share volume, with an average of 1,403 symbols traded on a June day, or roughly 12% of listed securities.
It is also not a scaled-down copy of the day session. Exchange-traded products account for 61% of overnight volume against 21% during core hours, while sub-dollar stocks drop to 2.7% of overnight volume against 13.5% in core hours. The overnight book is not merely thin. It trades different things.
That matters for the cannibalization argument. A cohort buying US large caps at 3 a.m. is not competing for flow that was going somewhere else at 3 a.m., because at 0.11% of total volume there was very little flow there to take.
What growth looks like when it is additive
The difference between expansion and rotation shows up at issuer level. In July, bStocks recorded roughly $7.4 billion in DEX volume, 85% of all tokenized equity trading on decentralized exchanges. Over the same month, sector-wide DEX volume rose from about $2.9 billion in June to roughly $8.8 billion, while the previous leader’s volumes were broadly unchanged, per Binance Research.
Growth that leaves the incumbent issuer flat is expansion of the addressable market, not redistribution inside it. The user data points the same way. Binance reports that 41.5% of bStocks users began their traditional finance investment journey through the token itself, which describes people arriving rather than relocating.
The clock tells the same story from another angle. Monthly weekend volume in perpetuals tied to traditional-market assets across crypto exchanges grew from roughly $4.5 billion to $28 billion by mid-August 2026. Weekend volume cannot be taken from venues that are closed.
The honest limit
None of this has been tested at scale. Combined bStocks volume equals 0.3% of trading volume in the underlying stocks and ETFs, up from 0.01% six weeks earlier, and matching 10% would take a further 33.4x expansion. The additive finding holds over a period in which there was not much to compete over.
The second limit concerns who is arriving. Institutional participation in digital assets is rising rather than falling: institutions accounted for 72% of spot volume on one large over-the-counter desk in the first half of 2026, against 59% a year earlier Professional counterparties broadened the range of assets they trade by 24% over two years. Retail broadened by 76%
Institutions are choosier. A cohort becoming steadily more institutional will eventually optimize for execution quality rather than access, and that is the point at which the two markets begin competing for the same flow. On a 0.3% base, that point has not arrived.
Additive until proven otherwise
The evidence available today points to expansion rather than displacement: new hours, new geographies, participants who were not in the market before. That reading holds for now because the two markets have barely met.
The reason to keep watching is that additive and redistributive only start to look different once the on-chain segment is large enough for the difference to cost someone something.
