Arthur Hayes Bets $2.2 Million on SYN, Backing Hypercall to Challenge Deribit

A $2.2 Million Vote of Confidence

Arthur Hayes, the co-founder and former chief executive of derivatives exchange BitMEX, has placed a fresh bet on the Hyperliquid ecosystem, buying roughly $2.2 million of synapse (SYN) and publicly endorsing the project behind an onchain options exchange.

The purchase, made on June 29 through over-the-counter trading firm Flowdesk, totaled about 6.16 million SYN tokens. Hayes, not one to keep quiet, subsequently took to X and commented:

Hypercall is an onchain options trading protocol built on Hyperliquid’s HyperEVM, the smart-contract layer of the fast-growing Hyperliquid network. The platform lets users trade options, with positions tradeable around the clock and risk capped at the premium a trader pays. Moreover, it has been developed by the team behind Synapse, whose SYN token is the asset Hayes bought.

A Run-Up in SYN

The endorsement landed on a token that was already on a tear as SYN surged more than tenfold in June, and Hayes’s purchase and public backing added fuel, with Synapse’s market capitalization climbing toward the $55 million to $60 million range and daily trading volume running above $95 million in the wake of his comments.

Hayes commands an unusually large following among crypto traders, both for his market essays and his willingness to put capital behind his theses. Not only that, he has become one of the most closely watched voices in the Hyperliquid orbit, repeatedly championing the network’s HYPE token, at one point setting a $150 price target, though his wallet activity has not always matched his rhetoric.

Bitcoin.com News reported recently that a wallet linked to Hayes sold HYPE near $54 before buying back in at a higher price, a sequence that drew attention to the gap between his public calls and his trades.

Targeting Deribit’s Turf

Deribit has been the dominant venue for crypto options, a corner of the market long underserved by decentralized platforms because options are harder to build onchain than simple spot or perpetual-futures trading. By putting forth Hypercall as a credible challenger, Hayes is betting that Hyperliquid’s infrastructure can finally support a decentralized options market at scale and that SYN is the way to gain exposure to that bet.

That said, an endorsement and a price spike are not the same as trading volume, open interest, and users, the metrics that ultimately decide whether an options DEX can pressure an incumbent like Deribit. For the time being, Hayes and his $2.2 million bet have put a considerable megaphone behind the idea and the next thing to look out for is whether Hypercall can convert the hype and capital into durable trading activity before the attention inadvertently fades.
