On September 1, 2026, during the morning session, SHEIN (SHEIN International Holdings Limited) debuted with the aura of a "global cross-border e-commerce giant," ringing the bell on the Hong Kong Stock Exchange. The stock is referred to as SHEIN-W with code 0625, with an IPO price of HKD 48.56 per share, raising approximately HKD 13.6 billion, corresponding to an estimated valuation of around USD 26 billion. Almost simultaneously, at 10:45 AM Beijing time, another screen lit up with the USDT-denominated Quanto perpetual contract code HK0625USDT on the Binance contract platform, offering up to 20 times leverage and 24-hour continuous trading, dragging a newly listed Hong Kong stock into the arena of crypto derivatives. On the Hong Kong side, SHEIN's stock price dropped to around HKD 43.72 on its first trading day, a decline of about 10% from its issue price, signifying a "breakdown" on the first day, leading to a massive valuation debate in the traditional IPO narrative. On Binance’s side, similarly referring to SHEIN-W's Hong Kong stock price, the long and short positions of HK0625USDT can continue to leverage on this newly listed stock's value after the Hong Kong stock market closes, free from trading session restrictions. On this day, SHEIN's price was no longer solely part of the daytime auction on the Hong Kong Stock Exchange; it was split into two curves: one pulled by underwriters, institutions, and retail investors under the IPO framework, and the other leveraged by global crypto traders in perpetual contracts, reflecting expectations. This synchronously born "dual-market" structure marks the beginning of the overlap between the traditional IPO pricing discovery mechanism and the pricing logic of crypto derivatives, with a new linkage chain rapidly being built using SHEIN as a sample.

SHEIN's Hong Kong Stock First Day Breakdown: The Shine of USD 26 Billion Diminishes

As a prominent cross-border e-commerce platform within the global fast fashion sector, SHEIN was previously hyped as a rare "new economic large-cap stock" story in Hong Kong: with an IPO price of HKD 48.56 per share, raising approximately HKD 13.6 billion—which corresponds to an issuance valuation of around USD 26 billion—on paper, it was a standard capital feast. On the first day of trading, SHEIN-W (0625) still started under the spotlight but quickly reversed during the trading session—the stock price briefly dropped to about HKD 43.72, a drop of about 10% from its issue price. While this drop itself isn't shocking, combined with labels such as "global brand," "USD 26 billion valuation," and "extremely high attention," the psychological gap formed was much greater than the number itself; a new large IPO, originally perceived as stable, instantly filled a prominent gap on the trading board.

A roughly 10% pullback in the middle of trading equated to a preemptive opening of the valuation discussion's "safety valve," with the market beginning to vote with its feet to test whether SHEIN's growth story warranted this USD 26 billion pricing label. Hedge funds and long-term capital found it challenging to simply regard it as a "star IPO" they had to participate in, nor would they assume the first-day gains could be mindlessly collected as a habitual result. The first-day breakdown shifted the focus on SHEIN from "how much higher can it go" back to colder questions like "where is the growth ceiling" and "will the current valuation be digested in the coming years." For funds accustomed to viewing large-cap new economy stocks as stable arbitrage opportunities, SHEIN's first-day performance served as a clear reminder that in the Hong Kong stock market, the glow of large-cap listings no longer equates to an automatically effective first-day profit ticket.

Binance's Perpetual Introduction: USDT Leverage Betting on SHEIN

While the Hong Kong Stock Exchange was still digesting the first-day breakdown, the clock struck 10:45 on another front. Binance's contract platform launched the HK0625USDT U-denominated Quanto perpetual contract, using USDT as the margin and settlement unit, yet firmly tethering the underlying price to SHEIN-W (0625) on the Hong Kong Stock Exchange. For users accustomed to trading on-chain, this meant there was no need to open a Hong Kong stock account or exchange currency; as long as they held USDT, they could directly bet on the rise or fall of this new stock on a familiar interface. On the surface, this was merely Binance’s continuation of its line of RWA derivatives tracking traditional stocks, yet in essence, it created a leveraged channel specifically for SHEIN between the Hong Kong stock market and the crypto world.

The tension of this channel arises from leverage and time. The HK0625USDT contract supports up to 20 times leverage and allows for 24-hour continuous trading, sharply contrasting with the Hong Kong stock spot market, which is only active during limited daytime sessions and struggles to amplify leverage. Any intra-day decline of about 10% can be massively amplified in contract terms as severe emotional fluctuations. According to a single source, the minimum trading quantity for this contract is only 0.01 HK0625, corresponding to a nominal value of about 5 USDT, thus enabling even very small pure crypto accounts to participate in the long and short tug-of-war over SHEIN’s valuation, allowing the story of this new stock to continue being rewritten in a realm priced in USDT, characterized by high leverage and 24-hour fluctuations.

Pre-Market 15% Flash Drop: Crypto Players Bet on Breakdown First

Before Binance leveraged emotions to a 20-time leverage on HK0625USDT, an even earlier "vote" was cast by the pre-market of Trade.xyz. Before SHEIN officially rang the bell on the Hong Kong Stock Exchange, this closely connected platform to the crypto world experienced an approximate 15% flash drop in related contracts—before the opening bell of the Hong Kong stock market even rang, the breakdown script was already half written on-chain and in front of screens. Ironically, data shows that the pre-market price was roughly consistent with the subsequent spot price after the opening of the Hong Kong Stock Exchange, resembling an exam paper released early, throwing the question of "will there be a breakdown" to the few players willing to bet early, to later confirm the answers when officially listed.

However, this privilege of early pricing is not without cost. The volumes, participant numbers, and matching details of the pre-market trading remain undisclosed, meaning those accounts betting on Trade.xyz were, in essence, taking on all the risks of slippage, extreme volatility, or emotional misjudgment in an environment with unclear depth and opponents; the benefit was that once correct predictions were made, they could lock in the price difference gains from breakdown expectations before Hong Kong stock investors entered the market. On the first day, SHEIN’s spot price dropped to around 10% from its issue price, mirroring the approximately 15% flash drop in the pre-market, causing the sentiments of these crypto players to naturally overlay onto the Hong Kong stock board when officially listed, transforming what originally belonged to traditional IPO first-day trading into a price experiment jointly inscribed by on-chain expectations and off-chain emotions.

Day Trading vs. Overnight Betting: Hong Kong Stocks and On-Chain Pulling Each Other

The daytime trading of Hong Kong stocks has its boundaries; SHEIN-W is only matched during fixed intervals. After the morning auction and the afternoon closing bell, the stock 0625 on the Hong Kong Stock Exchange is put on pause. However, on the same timeline, the HK0625USDT perpetual contract does not distinguish between night and day; it has been available for 24-hour continuous trading since its launch at 10:45 AM Beijing time on September 1. The result is that the same underlying price is determined during the day by Hong Kong stock investors, locked in the after-hours session by the Hong Kong Stock Exchange in the afternoon, and then "opened" again at night by crypto traders, revaluing it on-chain. The first-day drop of about 10% in spot price is not an isolated point but has already been previewed by the approximate 15% flash drop in the previous evening’s Trade.xyz pre-market, and subsequently chewed and dissected multiple times with high-frequency repricing in HK0625USDT’s after-hours trading.

Investors across different circles are thus tied to a cross-market price chain. The allotted shares in Hong Kong stock accounts saw the stock drop to HKD 43.72 during the first day, mostly passively bearing floating losses in the spot market; while crypto traders could continue placing orders through HK0625USDT after the Hong Kong stock market closed, using USDT as margin, leveraging up to 20 times to amplify their judgments on the same event. Pre-market participants provided the breakdown discount early on Trade.xyz, Hong Kong stock investors validated this pricing during the day trading with transaction volumes, while on-chain contracts took up the baton of "price discovery" after the Hong Kong stock market closed: some used it to hedge positions off-chain, while others purely bet on the fermentation of emotions. Since HK0625USDT supports high leverage, a similar movement of around 10% in the underlying can amplify into multiple times of profit and concentrated clearing at the contract level, leading to a rewriting of the traditional concept of "first-day breakdown" into a more intense, continuous volatility experiment within the crypto world, tightly linking the daytime trading of Hong Kong stocks with overnight bets on-chain.

The Next Stop for RWA Perpetuals: Will More IPOs Be On-Chain?

SHEIN's first-day breakdown on the Hong Kong Stock Exchange, coupled with Binance's launch of HK0625USDT U-denominated Quanto perpetual contracts at 10:45 AM on September 1, locked itself in the same temporal perspective, becoming a scene sample of the first profound synchrony between traditional equity financing and crypto leveraged speculation: on one side is the offline IPO priced at HKD 48.56, which briefly fell to around HKD 43.72, dropping about 10%; on the other side is the on-chain perpetual that uses an underwriting reference for SHEIN-W's Hong Kong stock price, priced in USDT for settlement, supporting up to 20 times leverage, and facilitating 24-hour trading. The fact before us is that Binance has continued to release contracts tracking US stocks and Hong Kong stocks in recent years; this HK0625USDT is just a piece of its RWA derivative strategy puzzle. This suggests that every attention-worthy IPO could potentially be instantaneously "copied" into a perpetual betting table, allowing valuation divergences originally existing only in roadshows, price inquiry books, and first-day trading sessions to be dragged into an always-open on-chain market for continued tearing. Yet it must also be acknowledged that currently, we do not see the fund rates or marking price rules for HK0625USDT, nor do we have actual transaction volumes, positions, or clearing data. Regulatory attitudes and cross-market liquidity are also undecided, and under such information boundaries, simply extrapolating SHEIN as a long-term reusable arbitrage paradigm is irresponsible towards risk and reality. What truly requires observation is how this compounded mechanism will be reenacted or proactively corrected by the market when the next IPO goes on-chain.
