The traditional trading week is becoming less relevant for certain market events.
U.S. equity markets operate for only 32.5 hours per week, equal to 19.3% of the total week, while those regular sessions still account for 87.2% of U.S. equity volume. The remaining 80.7% of the week has historically offered limited access to traditional equity markets.
That gap is now becoming a market of its own.
RWA-linked perpetuals allow traders to maintain exposure to equity-linked assets, ETFs and even selected pre-IPO companies outside normal U.S. market hours. Recent events around the September 16 FOMC decision, September 17 SEC Innovation Exemption, September 21 S&P DJI rebalance and Anthropic's expected IPO provide four different examples of how this market is developing.
The important question is not simply whether assets can trade 24/7.
It is whether price discovery is increasingly happening before traditional markets reopen.
The Fed Decision Tested Overnight Price Discovery
On September 16, 2026, the Federal Open Market Committee raised the federal funds target range by 25 basis points to 3.75%-4.00%.
The decision was unanimous at 12-0, but the dot plot delivered the stronger signal. 16 of 18 FOMC participants projected at least one additional rate increase by the end of 2026.
That was a major change from the start of the year, when markets had been pricing roughly four rate cuts.
The Treasury market was also moving. The U.S. 10-year yield had increased from 4.76% to 5.01% during September, a 25-basis-point rise, adding to the sensitivity around inflation, oil prices and future Fed policy.
The Fed statement arrived at 18:00 UTC, only two hours before the U.S. cash-market close.
That left a relatively narrow window for traditional equities to respond.
Perpetual markets, however, remained open.
From Wednesday's close to Thursday's U.S. equity open, several contracts recorded substantial moves:
Contract| Overnight moveSPYUSDT| +1.11%TMFUSDT| +2.45%TBTUSDT| -1.32%UVXYUSDT| -5.94%
Across 16 equity-linked perpetuals, the median contract captured 97% of the subsequent opening gap.
The individual figures were also striking:
SPY: 91%QQQ: 97%IWM: 99%TMF: 104%UVXY: 96%
The directional hit rate across the 16-name sample was 100%, while approximately US$1.02 billion traded while U.S. cash markets were closed.
This does not mean perpetual prices perfectly predict the next session. The data instead shows that a significant amount of the next session's directional move had already been reflected in an always-open market.
The SEC Announcement Produced a Different Reaction
The next test came from regulation rather than monetary policy.
On September 17, the SEC announced temporary conditional exemptions covering certain distributed-ledger venues trading tokenized NMS stocks and certain liquidity providers. The exemptions are scheduled to run until September 17, 2031, subject to their conditions and possible modification.
The timing was important because the announcement arrived around the U.S. market close.
The response was concentrated in crypto-linked equities rather than the broader equity market.
From Thursday's 20:00 UTC close through Friday's 13:30 UTC open:
HOOD +4.67%CRCL +4.43%BMNR +4.18%MSTR +4.04%COIN +3.24%
Meanwhile:
SPY -0.16%
This created a clear separation between the broader market and companies more directly connected to the crypto and tokenization theme.
But there was an important difference from the FOMC example.
The perpetual market's median priced-in ratio was approximately 140% of the eventual opening gap.
In other words, the overnight market correctly captured the direction, but the magnitude was subsequently adjusted when traditional cash-market liquidity returned.
That distinction is important.
Continuous trading can provide earlier price discovery without guaranteeing precise price discovery.
The overnight market can tell traders where positioning is developing, while the opening auction and deeper cash liquidity can still change the final magnitude.
The Weekend Became a Tradable Event
The next example moved beyond overnight trading.
The S&P DJI rebalance became effective before the September 21, 2026 Monday open. The rebalance had already been announced on September 4, meaning traders had several weeks to position around the event.
During the market closure surrounding the rebalance, 198 TradFi perpetuals recorded US$7.25 billion in trading volume.
That is a much broader market than a single stock or ETF.
The index additions gained an average of 1.01%, compared with 0.39% for SPY.
That represented approximately 0.6 percentage points of relative performance against the benchmark.
But the individual results were far from uniform.
The most heavily traded addition by notional was SNDK, with approximately US$744 million traded.
Its return?
Only +0.30%.
That is an important detail because it shows that simply being added to an index did not automatically determine the strongest individual performance.
With 24/7 perpetual markets, traders could take different positions on individual constituents throughout the weekend instead of waiting for Monday's opening session.
The market was therefore not only trading the index event.
It was trading the differences between individual names.
Anthropic Shows How Early Price Discovery Can Begin
The most unusual part of the report is arguably the pre-IPO market.
Anthropic does not yet have publicly traded shares, but a perpetual market is already allowing eligible traders to form views around its implied valuation.
In September 2026, Anthropic perpetual trading reached US$643 million in month-to-date volume, already exceeding the US$590 million recorded during all of August.
Across 12 venues:
Binance accounted for 32% of September volume.
Industry open interest reached approximately US$80 million, with Binance representing 39% of that open interest.
On Binance alone, open interest increased from US$16.6 million to US$31.2 million over 30 days.
That is an 88% increase.
The price had also moved substantially.
From August 1 to September 21, the Anthropic perpetual increased from approximately US$1,437 to US$2,091, representing a 45.5% increase.
Then came reports that Anthropic had pushed its expected IPO timing toward November.
The weekend reaction was relatively small.
The perpetual moved from approximately US$2,103 to US$2,084, a decline of just 0.89%.
At the same time, the OpenAI perpetual gained approximately 3.00%.
The limited Anthropic reaction does not prove exactly how much of the IPO-delay information had already been priced in. It does, however, show that a market was already available to absorb company-specific information before a conventional public listing.
And there is an important distinction:
Trading the Anthropic perpetual does not provide ownership of Anthropic shares or an entitlement to an eventual IPO allocation.
It is derivative exposure to a market-implied price
Four Events, Four Different Types of Information
These examples cover very different catalysts:
September 16: monetary policySeptember 17: securities regulationSeptember 21: index rebalancingSeptember 2026: pre-IPO company developments
Yet the underlying mechanism was similar.
Information arrived when traditional equity markets were closed or unavailable, and perpetual markets provided a venue for traders to adjust exposure immediately.
That is where the significance of RWA-linked perpetuals becomes clearer.
They are not simply extending trading hours.
They are creating a separate layer of continuous market-based expectations around traditional assets and events.
The Data Behind the Shift
Several figures from the September 22 Binance Research report illustrate the scale:
19.3% — share of the week occupied by regular U.S. equity sessions87.2% — share of U.S. equity volume occurring during those sessionsUS$1.02B — perpetual volume outside regular U.S. hours after the FOMC97% — median opening-gap capture across 16 equity-linked perpetuals100% — directional hit rate in the 16-name FOMC sampleUS$7.25B — TradFi perpetual volume around the S&P rebalance weekend198 — TradFi perpetual contracts included in that weekend activity1.01% — average return of S&P rebalance additions0.39% — SPY return over the same comparisonUS$744M — SNDK notional traded, the largest among the selected additionsUS$643M — Anthropic perpetual volume in September MTDUS$590M — Anthropic perpetual volume during August32% — Binance share of September Anthropic volume39% — Binance share of industry Anthropic open interestUS$16.6M → US$31.2M — Binance Anthropic open interest over 30 days+88% — increase in that open interest+45.5% — Anthropic perpetual price change from August 1 to September 21
These figures point to activity, not merely theory.
What This Means for Market Structure
The biggest change may be the reduction in the importance of the traditional opening bell.
For decades, the closing bell created a natural pause. A major announcement after hours could generate a large gap when trading resumed because investors had to wait for the next session to express their views through conventional markets.
That structure is becoming less absolute.
A Fed decision can be repriced overnight.
regulatory announcement can move crypto-linked equities before the next open.
An index rebalance can be traded throughout the weekend.
A private company's valuation can develop a liquid derivative market before its shares are publicly listed.
This does not eliminate opening gaps.
Instead, it potentially moves part of the price-discovery process earlier.
The September data also shows why the distinction between direction and magnitude matters.
The FOMC sample showed a 97% median capture of the opening move, while the SEC-related episode had a 140% median priced-in ratio.
So 24/7 pricing should not automatically be interpreted as a perfect forecast of the next cash-market price.
It is better understood as another layer of information about how traders are positioning when traditional markets are closed.
The Bigger Takeaway
The RWA narrative is often discussed in terms of tokenizing assets.
But the more interesting development may be what happens after an asset becomes tradable on-chain.
Once a market can operate continuously, the traditional distinction between “market hours” and “market closed” becomes less meaningful.
The September 2026 examples show four different stages of that transition:
Macro information → overnight repricingRegulatory information → sector-specific repricingKnown index events → weekend positioningPrivate-company developments → pre-IPO price discovery
The numbers are still early, and perpetual markets have their own risks, including funding costs, liquidity differences and the possibility that overnight prices diverge from the eventual cash-market opening.
But the direction of market structure is becoming clearer.
The question is no longer whether investors can trade outside the traditional session.
They already can.
The more important question is:
If information can be priced 24/7, how much of the “opening bell” will still remain as a true starting point for price discovery?
