Opinion

IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS EASTERN DIVISION

TAEWOO KIM, KASHYAP PATEL, KERRY WOOLLEY, and KEN WORSHAM, individually and on behalf of all others similarly situated,

Plaintiffs, Case No. 23 CV 2921 v. Hon. Georgia N. Alexakis JUMP TRADING, LLC, JUMP CRYPTO HOLDINGS, LLC (f/k/a 1HOLD1 LLC), KANAV KARIYA, and WILLIAM DISOMMA,

Defendants.

MEMORANDUM OPINION AND ORDER Plaintiffs Taewoo Kim, Kashyap Patel, Kerry Woolley, and Ken Worsham bring this suit individually and on behalf of a putative class against Jump Trading, LLC, its cryptocurrency arm Jump Crypto Holdings, LLC, and two of Jump Crypto’s executives. They allege that defendants violated state and federal law by scheming with Terraform Labs Pte. Ltd. (“TFL”) to manipulate the price of a stablecoin called TerraUSD (“UST”). Defendants now move to compel arbitration pursuant to an agreement plaintiffs signed with TFL. For the reasons set forth below, the Court denies defendants’ motion. LEGAL STANDARD The Federal Arbitration Act (“FAA”) governs the enforceability, validity, and interpretation of commercial contracts involving interstate commerce. See 9 U.S.C. § 1 et seq.; see also Jain v. de Mere, 51 F.3d 686, 688 (7th Cir. 1995). Under the FAA, arbitration agreements “shall be valid, irrevocable, and enforceable, save upon such grounds as exist at law or in equity for the revocation of any contract.” 9 U.S.C. § 2.

The FAA reflects a “liberal federal policy favoring arbitration and the fundamental principle that arbitration is a matter of contract.” AT&T Mobility LLC v. Concepcion, 563 U.S. 333, 339 (2011) (internal citations omitted). Because arbitration is a matter of contract, “a party cannot be required to submit to arbitration any dispute which he has not agreed so to submit.” Howsam v. Dean Witter Reynolds, Inc., 537 U.S. 79, 83 (2002) (quoting Steelworkers v. Warrior

& Gulf Nav. Co., 363 U.S. 574, 582 (1960)). Before ordering arbitration, it is a court’s role to determine whether a valid contract exists. See Janiga v. Questar Capital Corp., 615 F.3d 735, 742 (7th Cir. 2010). At the same time, “parties may agree to have an arbitrator decide not only the merits of a particular dispute but also ‘gateway’ questions of ‘arbitrability,’ such as whether the parties have agreed to arbitrate or whether their agreement covers a particular controversy.” Henry Schein, Inc. v. Archer & White Sales, Inc., 586 U.S. 63, 68 (2019) (citing Rent-A-Ctr., W., Inc. v.

Jackson, 561 U.S. 63, 68–69 (2010)). When parties agree to arbitrate arbitrability, a court may not disregard this “additional, antecedent agreement,” even when the argument for arbitration appears “wholly groundless.” Id. at 68–72. To determine whether parties have agreed to arbitrate questions of arbitrability, there must be “clear and unmistakable evidence that they did so.” First Options of Chi., Inc. v. Kaplan, 514 U.S. 938, 944 (1995) (cleaned up) (quoting AT&T Techs., Inc. v. Commc’ns Workers of Am., 475 U.S. 643, 649 (1986)). The party seeking to compel arbitration bears the burden of showing arbitration is the appropriate venue. See A.D. v. Credit One Bank, NA, 885 F.3d 1054, 1063 (7th Cir. 2018).

FACTUAL BACKGROUND1 In 2018, Do Kwon and his company TFL began creating the Terra blockchain. [60] ¶ 43. The next year, TFL began to sell UST and its related digital asset, LUNA. Id. ¶¶ 2, 43, 47. LUNA was the native token of the Terra blockchain. Id. ¶ 43. UST, by contrast, was designed as a “stablecoin,” a type of digital asset intended to be more stable than other cryptocurrencies by pegging its value to another asset. Id. ¶¶ 2, 38,

45. UST was continuously pegged to the U.S. dollar, which, according to plaintiffs, was meant “to appeal to the public as a safe crypto asset to serve as a store of value and medium of exchange.” Id. ¶ 2; see also id. ¶ 44. However, instead of being backed by actual dollars, TFL maintained UST’s price by minting and burning UST in parallel with LUNA. Id. ¶ 45; see also id. ¶ 38 (describing “one of two ways” that “a stablecoin’s peg can be maintained”). Jump Crypto was one of TFL’s early partners. Id. ¶¶ 3, 48. From November

2019 to September 2020, it entered into a series of agreements with TFL to borrow tens of millions of LUNA tokens and provide “market-making” services to TFL in exchange for the opportunity to buy discounted LUNA tokens. Id. ¶¶ 3, 50–57. In May

1 Resolving this motion does not require a thorough recounting of the underlying facts, but to provide some context for the parties’ dispute, the Court sets out key allegations from plaintiffs’ amended complaint. The Court accepts those allegations as true only for purposes of this motion. 2021, TFL’s algorithm pegging UST to $1 failed, and UST’s market price fell. Id. ¶¶ 4, 73. In response, plaintiffs contend TFL and Kwon “secretly schemed with

Defendants to manipulate and pump the market price for UST by making secret, coordinated trades to prop up UST to its $1 peg.” Id. ¶ 4. As part of this scheme, plaintiffs further contend, Jump2 bought more than 62 million UST tokens in May 2021, which “artificially inflate[d]” UST’s price to $1 and “caus[ed] a corresponding rise in the price of UST.” Id. To reward Jump for this alleged manipulation of the UST market, “Kwon agreed to modify TFL’s prior agreements with Jump and instead

unconditionally sell 65 million LUNA tokens to Jump at a greater than 99% discount from their then-current market price.” Id. ¶ 5, see also id. ¶¶ 77–79, 105. Plaintiffs say Jump later sold these LUNA tokens for a $1.28 billion profit. Id. ¶¶ 5, 84, 106. According to plaintiffs, defendants “actively concealed and aided and abetted TFL’s and Kwon’s concealment of Jump’s May 2021 intervention to maintain the artificial $1 peg for UST.” Id. ¶ 7; see also id. ¶¶ 111–14. By May 2022, the price of UST collapsed entirely, causing an alleged loss of nearly $19 billion in UST holdings,

including a loss of more than $2 million in UST for the four named plaintiffs. Id. ¶¶ 7– 8, 109. Plaintiffs maintain that, as a whole, the class sustained “billions of dollars in actual damages under applicable law.” Id. ¶¶ 8, 128. In May 2023, Kim brought a putative class action complaint against Jump Trading and Kanav Kariya, the president of Jump Crypto, alleging violations of the

2 As plaintiffs do in their amended complaint, the Court uses “Jump” here to refer collectively to defendants Jump Trading, LLC, and Jump Crypto. [60] at 1. Commodity Exchange Act (“CEA”), 7 U.S.C. § 1 et seq., Commodity Futures Trading Commission (“CFTC”) regulations, 17 C.F.R. § 180, and common law unjust enrichment. See generally [1]. In August 2024, plaintiffs brought an amended class
