An arbitrator ruled in Circle's favor in February 2026, rejecting Heka Funds' roughly $49 million lost-profits claim and awarding Circle $166,643.25 in expert fees. The filings became public in mid-July 2026, and on July 6 Circle petitioned a U.S. federal court in Massachusetts to confirm the award under Case No. 1:2026cv13095. That's the legal scoreboard. The more consequential story is what the case reveals about how primary stablecoin access actually works when things go wrong.
Heka ran an arbitrage fund called Elysium. Tether invested roughly $800 million into it, accounting for around 75% of assets by the time of arbitration, and waived USDT minting fees along the way. On the USDC side, Circle controlled Heka's primary account: its ability to mint new USDC and redeem back to dollars at par, directly with the issuer.
During the March 2023 SVB de-peg, Circle let Heka redeem more than $587 million in USDC. That looks generous in isolation. By November 2023, though, Circle dropped Heka's redemption limits to zero. On December 1, 2023, the account was suspended. A $100 million redemption request filed in February 2024 was denied outright. Heka took the dispute to arbitration. Lost.
Two markets, one choke point
Stablecoins trade freely on secondary markets like any other token. The primary rail is different. Only approved counterparties can mint directly or redeem back to dollars with the issuer, and that access is governed by account agreements, compliance reviews, and risk flags that most operators never read closely until they need them. When the primary door closes, secondary spreads widen fast, and any strategy built on instant convertibility runs into real trouble.
What makes the Heka case instructive is the combination of factors: concentrated backing from a rival issuer, an arbitrage strategy that was probably visible to Circle through transaction patterns, and no apparent fallback when limits moved. The arbitrator found no wrongdoing on Circle's part. That's the point. Issuers have wide discretion over primary access, and exercising that discretion is not the same as breaching a contract.
For treasuries, market makers, and crypto funds running any meaningful size in stablecoins, the practical takeaway is straightforward. Redemption limits are not fixed infrastructure. They're negotiated, reviewable, and revocable. Pre-negotiating escalation paths and maintaining primary accounts with more than one issuer are not hedges against unlikely events. The Heka timeline, from $587 million redeemed in March 2023 to a $100 million request denied eleven months later, shows how quickly the picture can shift.
The onboarding paperwork almost nobody reads carefully is exactly where these terms live.
