Compiled by: TechFlow

TechFlow Summary: With Anthropic officially filing its S-1 prospectus with the SEC and launching its IPO next week, pre-IPO perpetual contracts in the crypto market are serving as a price discovery testing ground before the debut of this unicorn. As of November 10, platforms such as Hyperliquid and OKX have accumulated over $260 million in open interest for related contracts.

The Coin Metrics research team deconstructs the pricing and rebasing mechanisms employed by TradeXYZ, OKX, and Entropy under three distinct denominator metrics: "Class A shares only," "Class A + Class N ordinary shares," and "fully diluted shares." It also reviews the price fitting performance of on-chain perpetual contracts around SpaceX's listing, highlighting cross-exchange spread risks during the settlement convergence period.

Key Takeaways

· Traders continue to build exposure to Anthropic's listing through pre-IPO perpetual contract markets. As of November 10, combined open interest across Entropy, TradeXYZ, and OKX futures markets related to Anthropic's valuation has exceeded $260 million.

· Although both OKX and TradeXYZ price Anthropic based on share price, they use different denominators for total outstanding shares. Due to inconsistent settlement rules, this discrepancy directly leads to cross-exchange price divergence.

· The current implied mean valuation of Anthropic in the pre-IPO perpetual market is approximately $1.4 trillion. Its latest revised S-1 prospectus shows that fully diluted shares total approximately 18 billion, with an offering price range set at $70 to $78.

Introduction: Pre-IPO Perpetual Contracts and Prospectus Release

On October 26, 2026, Anthropic officially unveiled its S-1 prospectus. As it is expected to list formally next week, speculative capital is actively positioning financial exposure in the pre-IPO derivatives market.

We previously analyzed the case of Entropy, a builder on the Hyperliquid HIP-3 protocol, launching its pre-IPO market for Anthropic. Data shows that Hyperliquid perpetual contracts not only provide ample liquidity and extremely tight bid-ask spreads, but their order book depth is more than capable of competing head-to-head with top centralized exchanges (CEXs).

Before the S-1 document was made public, OKX was the only platform supporting trading Anthropic valuations based on "share price," while most other platforms used "market capitalization" dimensions for pricing.

After the S-1 document was published, two major HIP-3 builders in the Hyperliquid ecosystem, Paragon and TradeXYZ, sequentially launched pre-IPO markets for Anthropic priced in share price.

This issue of State of the Network will dissect the differentiated impacts on prices and valuations across trading venues after the S-1 amendment clarifies the share count.

Deconstructing Anthropic's Cross-Platform Implied Valuation

Based on quotes across pre-IPO markets, investors' median valuation for Anthropic stands at approximately $1.4 trillion, a significant drop from previous highs exceeding $2 trillion. After Anthropic released its S-1 document and supplemented disclosures with specific share counts and an expected offering price range, overall market valuation expectations were further downgraded.

Why Total Issued Shares Directly Determine Pricing

Currently, the vast majority of platforms listing Anthropic pre-IPO contracts still use a "market cap-anchored" model. However, once Anthropic officially lists via IPO, all contracts must switch from a market cap valuation mode to a "per-share price" mode.

This is precisely the source of price mismatch caused by inconsistent settlement rules. Although quotes across all markets will eventually converge to the publicly traded ANT stock price post-listing, the path mechanisms for each platform to reach this endpoint differ significantly.

TradeXYZ: The Benchmark Anchor for ANT Valuation

On the same day Anthropic publicly released its S-1 prospectus, TradeXYZ, a Hyperliquid HIP-3 builder, simultaneously deployed its own Anthropic pre-IPO market.

Since October 26, TradeXYZ's open interest has surpassed $65 million, reaching four times OKX's position size in less than four days since launch.

TradeXYZ initially set the opening price for this ANT contract at $125, establishing a price discovery fluctuation band of plus/minus 50%. According to the offering plan, Anthropic intends to issue 825 million shares, with an offering price range between $70 and $78.

As of November 10, the ANT contract on TradeXYZ was quoting around $97, approximately 23% higher than the upper limit of the S-1 offering price.

In its contract design, TradeXYZ strictly anchors each contract to one share of Anthropic Class A common stock. This Class A stock is exactly what Anthropic plans to offer to the public in this IPO and will serve as the direct pricing unit upon its future Nasdaq listing.

When contracts transition from pre-IPO perpetuals to mainboard US equity perpetuals, their per-share valuation denominator includes only Class A common stock, completely excluding unexercised options, restricted stock units (RSUs), and other share classes. Serving as the industry's narrowest denominator benchmark, TradeXYZ naturally becomes the pricing reference anchor for measuring other pre-IPO markets.

OKX Market Structure and Rebasing Mechanism

OKX was the first to launch a per-share priced Anthropic pre-IPO market back in May 2026. Initially, OKX's preset denominator for total shares was 1 billion, meaning a contract quote of $1,500 implicitly valued the company at $1.5 trillion.

On June 30, to better align with actual expected share sizes, OKX executed its first rebase, significantly raising the calculation benchmark from 1 billion to 10 billion shares. This adjustment kept traders' nominal position values unchanged while proportionally lowering the quoted price per contract to one-tenth of its original value.

OKX will next execute another round of rebasing to accurately match the actual float of ordinary shares post-listing. During the rebase execution, OKX will force-settle realized PnL on existing positions and resume trading once parameters are reset.

Under OKX rules, the final settlement share count covers all ordinary shares immediately issued post-IPO (including Class A and Class N ordinary shares), but excludes unexercised options and unvested RSUs.

According to the S-1 amendment disclosure, this metric totals approximately 15.2 billion shares, significantly larger than TradeXYZ's denominator which only includes Class A shares. Consequently, its per-share settlement quotes are expected to converge downward toward the TradeXYZ benchmark line.

Entropy's Popularity and Dilution Discount

Also part of the HIP-3 ecosystem, Entropy uses a "total market capitalization"-based valuation model to price Anthropic contracts. Since its launch in August this year, the market's open interest has surpassed $175 million, leading among peer platforms.

During the listing transition, Entropy stipulates converting pre-IPO contracts into a per-share price calculated by dividing equity valuation by fully diluted shares, encompassing Class A shares, Class N shares, unexercised options, and unsettled RSUs.

Precisely because the identical total company valuation is diluted across the widest share denominator, Entropy's quotes have long maintained a certain discount relative to other trading venues, effectively front-loading maximum equity dilution effects. Based on current market conditions, Entropy traders are betting on an expected first-day IPO pop of approximately 20%.

Volatility Correlation of ANT Contracts During Pre-IPO Trading

Looking at risk correlation metrics, the Beta coefficient of Anthropic pre-IPO contracts relative to the Nasdaq 100 index (QQQ) is only 0.72, below 1. This indicates relatively limited sensitivity to broad tech sector volatility, reflecting market caution regarding how specific events may transmit to its valuation.

However, the contract's Beta coefficient relative to the S&P 500 reaches 1.15, demonstrating higher sensitivity to broader macro market fluctuations.

A highly similar correlation pattern previously played out in SpaceX's pre-IPO derivatives market. Prior to its official listing, the SPCX contract exhibited Beta coefficients of merely 0.22 relative to QQQ and 0.45 relative to the S&P 500.

Once SpaceX listed, these two Beta figures for SPCX rapidly surged to 1.43 and 1.97, significantly amplifying sensitivity to macro market trends.

Are Pre-IPO Perpetual Contracts an Effective Price Discovery Tool?

Reviewing the SpaceX listing precedent, its final IPO offering price was set at $135, while pre-IPO perpetual contracts were previously trading near $176. Even accounting for the first-day pop, pre-IPO contracts were still roughly 17% overvalued compared to the actual opening price, though contract prices quickly converged toward the actual SPCX stock post-listing.

Despite slight overpricing during the surge phase, the pre-IPO derivatives market has genuinely allowed on-chain retail traders to participate in and trade the "first-day IPO premium," a feature unique to traditional IPOs, for the first time.

Live data confirms this: within regular US equity trading hours one week post-SpaceX listing, the spread between SPCX perpetual contracts and the underlying US stock remained consistently within 2%, indicating that derivative prices rapidly achieved deep coupling with the spot equity market.
