Arthur Kaliyev accused of stealing $50,000 from model ex Lauren Mochen as gambling claims rock Ottawa Senators

Arthur Kaliyev's off-ice narrative is turning into something that sounds more like a headline than a hockey statistics sheet. The Ottawa Senators forward is now caught in a several accusations that including gambling, deceit, and a confusing financial situation.

His ex-girlfriend, model Lauren Mochen, told the New York Post that her three-year relationship with Kaliyev resulted in losses of over $50,000, leading to questions about the true extent of his issues.She talked about bounced checks, bank accounts that closed out of nowhere, and late-night calls that went from arguments to sheer desperation. Although the claims haven't been validated in court and no charges have been brought up, the pattern she outlines seems like a red flag.

Issues like gambling, addiction, and financial problems aren't unfamiliar in professional sports, but the depth of her narrative, along with the surrounding silence, has changed one player's personal life into one of the league's most awkward subjects of discussion.

Arthur Kaliyev’s ex-girlfriend traced over $50,000 lost through offshore betting links

Mochen stated that the more than $50,000 loss was part of a recurring issue connected to Kaliyev's gambling. She pointed out that he transitioned financial conversations to Snapchat to use disappearing messages and refused to watch anything but sports on TV, obsessively checking his phone and switching between games, as if he had bets on every result.

She told Walker, “He behaved as if he had bets placed on every single game that was on my TV.

He would sit there checking his phone, checking and flipping back and forth between games.”In October 2024, while they were in the process of opening a joint account at Chase Bank, a banker informed them that Kaliyev was banned from the main branches. This was due to someone using his Social Security number under his father Vadim Simakov's name to take out loans and credit cards.

They opted to open an account at BMO instead, with assistance from Kaliyev's agent, Ian Pulver, to block his parents from accessing it.Kaliyev shared a screenshot showing transactions on sites like Crypto.com and FanDuel, along with an associate who was placing bets on his behalf. Mochen traced PayPal transfers back to Bovada, an offshore betting site that is illegal in the U.S. and California, where they lived most of the time.Mochen asserted that Kaliyev owed roughly $50,000 to his teammates on the Los Angeles Kings for various fines, fees, group bets, and pools, according to a text from his best buddy, Igor Larionov II, who referenced Kings defenseman Drew Doughty. Another player from the Kings confirmed via Snapchat that the debts were still there.

In January 2024, just before his waiver, Kings GM Rob Blake held off on processing until Kaliyev cleared his outstanding trainer fees; Kaliyev texted Mochen on January 2, “Stuff like this makes me boil,” owing to cash shortages.

Mochen supplied him with cash, channeled through her friend Krissy Spaulding, who confirmed the setup but noted that repayment never occurred. Kaliyev was also allegedly kept out of practice because of unpaid tips.According to Mochen, the discussions about gambling escalated quickly. Following his injury in February 2024, Kaliyev made threats of suicide during lengthy calls that lasted three hours. She and Larionov reached out to Pulver, who noted the possibility of NHL/NHLPA support on March 11, 2024.Mochen proposed the Player Assistance Program on March 14, but Kaliyev turned it down, “No, don’t even start with the program, don’t even start. Please. Just take off the board right now.” He supposedly made physical threats towards her during their arguments, “I’m going to end you, I’m going to hurt you,” though never acted on it.Mochen described the pattern to the Post, “Every single time I brought up gambling, it was a freak-out... He’s screaming at me, ‘I’m a scumbag, I’m f–ked up. He hopes I die. He hopes I get hit by a car.’ Over me just saying, ‘Do you gamble?’”

The alleged check scam of summer 2023 sits at the center of the case against Arthur Kaliyev

The claims revolve around a scheme that Mochen says Kaliyev orchestrated in the summer of 2023, just about a month before a birthday trip to the Bahamas.

Kaliyev supposedly told her he had "accidentally" taken money from her PayPal account to pay workers at his family's shipping company, and that his mother, Rumiya Kaliyev, had given him a $400 check to repay her. He sent her a photo of the check, which Mochen deposited via mobile.

He claimed his bank account was frozen due to family issues and asked her to send him the $400 through Apple Cash, promising to pay her back shortly.Things got out of hand fast. In the following week, Kaliyev supposedly handed over more checks from the family business $1,500, two checks for $2,300 each, and another for $1,000 adding up to $7,500 and requested Mochen to deposit them and transfer the money online.When Mochen got to Miami for her vacation, she checked her bank account and discovered it was overdrawn by $7,000. Her bank reached out to her, saying the checks were fake and insisting on repayment to prevent her account from being closed.Mochen recounted the panic to the Post: “The bank calls me and says, ‘You cashed three fraudulent checks, who did these come from? Why did you do this?’ And right away, I panicked and was like, ‘No, no, no, I don’t know what’s going on.’ And I was like, ‘Can you guys double check? There’s just no way this is happening.’ The bank was like, ‘No, you need to pay the difference. Your account is negative, and once you do, we’re going to close your accounts.

You can’t have an account with us anymore.’”Mochen accused Kaliyev of using her personal details and a different phone number to open another PayPal account, stealing an additional undisclosed sum beyond the $14,114.88 she had tracked from her original account. She provided evidence for her claims through bank statements, text messages, and PayPal records that were examined by the Post.Mochen reported an incident to the police in Saginaw Township, Michigan, concerning larceny tied to the fraud dispute. She told the Post that she is contemplating pressing charges, but as of November 3, 2025, no charges have been made.Also Read: Conor Geekie gets jumped by Hendrix Lapierre and Trevor van Riemsdyk as 3rd period brawl shakes up Capitals vs Lightning showdown
