On June 12, the globally acclaimed commercial space giant SpaceX is about to create a historic IPO on NASDAQ. While the traditional capital market awaits the ringing of the IPO bell, the crypto market is already engaging in a real pricing rehearsal surrounding SpaceX's valuation.
With the innovative financial derivative of Pre-IPO perpetual contracts, the multitrillion-dollar listing game of SpaceX is unfolding early. As SpaceX disclosed the latest S-1A document, the mismatch between actual equity and initial estimated equity led to divergences among major crypto trading platforms regarding Rebase (share adjustment) rules, thereby opening a cross-platform arbitrage window with price differences of up to 10%.
With the same asset and IPO expectation, different trading platforms have launched a commercial battle, and the lack of uniform rules has given rise to an arbitrage feast.
Trading Platforms' Pre-IPO Contract Battles: SpaceX's IPO Revision Document as the Trigger
The commercial battle among crypto exchanges surrounding the SPCX Pre-IPO contracts primarily revolves around the "value dilution of the contract's underlying equity".
Initially, major trading platforms launched SpaceX's Pre-IPO contracts generally based on the market's estimated initial equity of 11.87 billion shares.
However, the first revised version of the S-1A document submitted by SpaceX on June 1 was like a deep-water bomb: data showed that, after experiencing a capital increase, SpaceX's actual total equity changed to 13.08 billion shares, which increased by about 10% compared to the initial estimate.
The increase in equity implies that the implied value per share has been diluted, directly leading all major trading platforms to face the same choice: to adjust contract rules to converge on the real per-share price (Rebase), or to maintain the status quo until listing?
In response to this change, the reactions of major mainstream trading platforms were distinctly different:
Binance: Cautiously step by step, triggering the Rebase mechanism
Last night (June 8), Binance issued a Rebase announcement, stating that it would convert SpaceX's Pre-IPO contract at a ratio of 1.1 to align with the diluted actual equity value.
In fact, Binance's Rebase action had long been on the horizon.
On May 21, when Binance launched SpaceX's Pre-IPO contract, it had already indicated in its announcement that the actual number of shares after listing might differ from the estimate, reserving the right to Rebase the contract.
On May 29, Binance released a document explaining the Rebase rules for IPO targets, promising to trigger adjustments if the share deviation exceeded 3%.
On June 3, after SpaceX delivered the updated S-1A document, the share deviation far exceeded 3%, leading to a high probability of Rebase by Binance.
On June 4, Binance released a Chinese version of the document. A series of actions sent a strong signal to the market, indicating that Binance was discussing and preparing a Rebase plan internally.
Ultimately, Binance decided to implement Rebase tomorrow (June 10), attracting significant attention from arbitrage funds.
OKX: Taking the initiative, completing a large-scale Rebase in advance
On June 2, OKX executed a Rebase of up to 12.52 times on SpaceX's pre-IPO contracts. After the adjustment, the actual total equity corresponding to SpaceX's pre-IPO contracts on OKX was 12.52 billion shares.
Although there is an apparent discrepancy with the 13.08 billion shares of actual total equity disclosed in the S-1 document, it did not impact individual stock prices.
According to PANews' investigation, 12.52 billion shares represent SpaceX's Basic Shares Outstanding, which only counts the ordinary and preferred shares that are about to be officially issued and on the shareholder register; while 13.08 billion shares represent its Fully Diluted Shares, which includes not only stocks but also unexercised options from the Employee Stock Ownership Plan (ESOP), convertible bonds, warrants, etc.
Essentially, these two metrics do not affect the final price mapping; they merely differ in calculation methods.
Trade.xyz (Hyperliquid): Silent refusal of Rebase, market-based pricing
Unlike the two centralized exchanges (CEX), Trade.xyz, based on the Hyperliquid HIP-3 market, follows an unconventional path as an RWA Perp DEX. Its official documents directly emphasize that the SPCX contracts on the platform track the price of SpaceX's actual Class A common stock and include numerous disclaimers stating "no Rebase execution".
After the revision of SpaceX's S-1A document, the price of the SPCX contract on Trade.xyz directly completed a drop of about $15 through market mechanisms, preemptively achieving self-pricing for equity dilution.
Thus, a dramatic scene formed in the market, with three trading platforms showcasing three different pricing logics: the same SpaceX, Binance is about to Rebase, OKX has already Rebased, while Trade.xyz silently refused Rebase.
It is this divergence in rules that laid the groundwork for the ensuing cross-platform arbitrage opportunities.
Feast of Smart Money: How Cross-Platform Arbitrage is Achieved?
The fragmentation of rules is often a breeding ground for arbitrageurs. In this game, the crypto "smart money" captured an extremely rare certainty alpha opportunity in the market.
Before Binance confirmed the implementation of the 1.1-fold Rebase, the market was in a mispricing state for a long time. Since Trade.xyz had already completed dilution pricing, while Binance was still trading at the old equity, the prices of the two diverged significantly, with the SPCX price on Trade.xyz even temporarily exceeding Binance's by 20 basis points.
As SpaceX's S-1A document was updated and Binance confirmed the 1.1-fold Rebase execution, the accumulated pricing difference triggered a low-risk arbitrage window with a maximum of up to 1,000 basis points.
The logic of this arbitrage strategy is not complicated: Binance will execute Rebase, while Trade.xyz will not, thus, at the moment before Rebase, prices on both sides converge to the same level line. However, once Binance completes the adjustment, its contract prices will be recalculated at a ratio of 1.1, while the prices on Trade.xyz will remain unchanged, creating a natural arbitrage space between them.
For example: if the SPCX prices on Binance and Trade.xyz were both quoted at $170 before Rebase, after completing the 1.1-fold Rebase, Binance's position quantity increases by 10%, resulting in a corresponding price drop to about $154.55. Meanwhile, the SPCX price on Trade.xyz remains anchored around $170. This leads to a natural price difference of over 10% between the two.
For arbitrageurs, this means being able to establish a long position on Binance while simultaneously establishing an equivalent short position on Trade.xyz, waiting for the final price to converge and thereby locking in the intermediate price difference revenue.
In CEX, similar arbitrage logic holds true. Arbitrageurs can go long 1 unit of SPCX on Binance at $170 while shorting 1.1 units of SPCX on already completed Rebase OKX at $160. Once Binance completes Rebase, the long position will automatically adjust to 1.1 units, while the price will also be divided by 1.1. As long as the "Binance price/OKX price ratio" is 1.1, arbitrageurs will still profit.
The brilliance of this path lies in that: arbitrageurs achieve delta neutrality in hedging positions between the two CEXs. Regardless of what level SpaceX's IPO stock price lands at, the contracts on both sides will eventually converge to the same price, allowing arbitrageurs to securely capture the over 3% certain profit in between.
However, as Binance released the Rebase announcement and a large amount of arbitrage funds flooded in, the price difference between different trading platforms is continuously being smoothed out, and the profit space is gradually diminishing; this arbitrage feast is nearing its end.
Looking back at the entire event, the true creator of the arbitrage opportunity was not SpaceX itself, but rather the different rules adopted by different platforms surrounding the same event. When there is a divergence in pricing rules for an asset across different platforms, it can create new alpha opportunities.
The "largest IPO in history" SpaceX has not even listed in the traditional capital markets, yet it has provided a classic arbitrage game case for the crypto market, once again demonstrating the crypto market's sensitivity to information and expectations. With the NASDAQ bell ringing on June 12, the real pricing battle is just about to begin.
