Suspicion about Yoo Si-min did not arise suddenly one day. However, in the fall of 2026, that suspicion is growing again, not from outside the ruling party, but from within. On September 22nd, on Media Today's YouTube channel, he described President Lee Jae-myung's explanation of prosecutorial reform as "deceiving the public until now." This was the part where President Lee, in a press conference on the 18th, initially spoke of the maximum possible plan as the separation of investigation and prosecution within the Ministry of Justice. The President then placed those words as the initial discussion of the past, adding that now prosecutors do not investigate at all and investigative agencies belong to the Ministry of Interior and Safety. Four days later, Yoo Si-min cut off the beginning and end of that statement, claiming it was completely different from the reform and presidential pledges of the Democratic Party he knew, and used the word "deception." The Blue House expressed regret, calling it a distortion of facts, and while rumors of legal action emerged, it was later settled with "nothing has been decided." In July, on Maebul Show, he had already said, "The reason reform has not happened for over a year is because the President does not want complete separation." As the same words were repeated, some of his supporters heard it as frank advice, while others heard it as irresponsible bombardment.
It's not surprising that critics are concerned about his remarks. Yoo Si-min's words have always drawn their power from authority rather than information. When his background as Minister of Health and Welfare, chairman of the Roh Moo-hyun Foundation, and commentator for 'Alileo' preceded his statements, unverified assertions sounded like facts. During the Cho Kuk situation, he almost daily provided commentary that framed the prosecution's investigation as a political maneuver. Whether that commentary was right or wrong, separate from court records, it was already a conclusion for the listeners. This time, the structure is the same. There's a difference between scrutinizing the gap between pledges and policies, and definitively stating that the public has been deceived. The former is commentary, the latter is closer to incitement. When someone with no public office, party position, or election responsibility brands a sitting president as deceitful, those words spread within the camp without verification. Kim Min-seok's call for restraint and the Blue House's first expression of regret are part of that crack. The concern isn't about disagreeing with his conclusion, but about the lack of a brake on how he reaches conclusions. Wrong statements can simply be corrected, but the word 'deception' remains even if corrected.
One of the reasons why there seems to be no brake is the property controversy. In the last days when public officials' assets were disclosed, his declared assets when he was appointed minister in 2006 were approximately 186 million won, and the cash in his name was around 15 million won, which was the sum of his wife's apartment in Goyang and his debts. This was less than other appointees in the same cabinet reshuffle. In 2007, his declared assets as minister were in the 260 million won range, and in 2008, his declared assets as a lawmaker went down to minus 270 million won if debts were excluded. After that, he left public office, and the obligation to disclose assets disappeared. The "100 billion won wealthy person" circulating online is not a confirmed figure. No land registry, stock balance, or tax data has ever been disclosed. In 2024, he directly denied the rumor of living in Seocho Acro River Park and said he lives in a villa in Bangbae-dong. The article that he lived in that apartment, where a dedicated 84 square meters exceeded 4 billion won, was, according to him, a misreport by a real estate media outlet that simply copied company information, and it remained uncorrected with only his name omitted. In July 2026, lawmaker Park Sun-won said on a broadcast that Yoo Si-min himself said that he "has accumulated so much wealth that it is difficult to do politics, and he pays a lot of income tax." This is a politician's statement, not a property statement disclosed in his own voice. There is no amount, only an impression.
However, that impression fuels suspicion. A person who earns tens of millions of dollars for decades solely from best-selling royalties, lecture fees, and YouTube revenue, and a person who has accumulated enough assets to give up politics, are not in the same category. It is true that books like 『My Contemporary Korean History』 and 『What is a Nation?』 have sold well for a long time, and it is also true that 'Alileo' was once a channel for explaining political camps. There is no basis to say that legal channels are entirely impossible. However, the claim that this path leads to 100 billion won cannot be explained without separate investment income or undisclosed asset movements. No matter how substantial the royalties, for an annual income in the hundreds of millions to accumulate to 100 billion over ten years, the remainder after taxes and living expenses would have to be almost entirely compounded. He does not provide that explanation. As he is not a public official, he has no obligation to do so. Silence without obligation, when combined with the authority of his statements, turns into suspicion. The observation that he cannot enter politics because he does not disclose his assets is therefore closer to a structural issue than a conspiracy. The moment he returns to the National Assembly, his assets will again be subject to disclosure, and his lecture fees, copyright income, and the gaps in between will become questions at a hearing. As long as he remains a writer, those questions are rumors, not records. Park Sun-won's remark that 'politics is difficult due to high taxes,' when read in reverse, is indistinguishable from saying that he is afraid of disclosure.
And ShillaJen is the name attached to that blank. At the 2015 Pexavec technology briefing at Yangsan Pusan National University Hospital, he gave a congratulatory speech as a former minister, stating that the fact that it had received US FDA approval and reached global phase 3 trials was proof that its efficacy had been largely demonstrated. Phase 3 clinical trials are not proof of efficacy, but rather tests to prove it. It is easy to imagine how that one sentence sounded to the ears of the victimized investors later on. At the time, on the side of the largest shareholder, there was Lee Cheol, former CEO of Value Invest Korea, who had ties to Nosamo and the People's Participation Party. Lee Cheol's VIK was the largest shareholder, holding 14 percent of ShillaJen's shares from September 2014 until the end of the following year, and Lee Cheol was later sentenced to 12 years in prison for large-scale investment fraud, among other charges. It was also revealed in court that illegal political funds had been handed over to Kim Chang-ho, former head of the Government Information Agency. After its listing in 2016, ShillaJen briefly ranked high in Kosdaq market capitalization but collapsed due to the suspension of clinical trials, and its management was prosecuted on charges of illegally profiting 190 billion won by acquiring bond with warrants without their own funds. Hundreds of billions of won of CEO Moon Eun-sang's assets were preserved for 추징.
What remains unconfirmed is broader. Allegations of "ruling party lobbying" and "Yoo Si-min's nominee investment" spread, primarily through Channel A's reporting and conservative YouTube channels. During the investigation, recordings and letters mentioning Yoo Si-min's name dozens of times led to separate legal battles, the conclusion of which was not the proof of lobbying but rather a dispute over the investigation methods. In June 2020, the Seoul Southern District Prosecutors' Office announced that after analyzing ShillaJen's accounts, they found no flow of funds leading to Yoo Si-min or the Roh Moo-hyun Foundation, and that the allegations of political lobbying were unconfirmed. The prosecution limited the scope, stating that they did not directly open the foundation's accounts but rather could not find a connection from ShillaJen's accounts. The following year, Yoo Si-min's side raised an issue with the answer, which included the phrase "related to ShillaJen," arguing that the foundation's financial information had been provided for other matters. Yoo Si-min himself stated, "No matter how much you dig, no water comes out," and "I don't know anything about it other than greeting them once at an event." The legal conclusion is close to a finding of no charges. However, the suspicion has not died. This is because a former minister gave a congratulatory speech prejudging the success or failure of clinical trials, a person from the same political community was among the major shareholders of that company, and after the company collapsed, only the management was punished while the surrounding network remained unexplained. The statement that the prosecution could not find money in the accounts and the statement explaining why he was there are different sentences. When the company was delisted in 2022, that congratulatory speech reappeared on investor forums.
So this controversy pits conspiracy theories and facts against each other in one sentence. 100 billion won is not a fact. At least, it's not a fact based on publicly available evidence. ShillaJen's involvement in profits is also not a fact according to the investigation's conclusion. At the same time, the statement that he is avoiding a political comeback without explaining the source of his wealth, the congratulatory speech that spoke of phase 3 clinical trials as proof of efficacy, and the habit of using the word 'deception' towards the incumbent president from an irresponsible position are facts. It may be a leap of logic for the public to connect these three. However, if such leaps are repeated, they become part of a person's image. He was once the face of the Participatory Government's intellectuals. After Roh Moo-hyun's retirement, he said he would go home but returned with the People's Participation Party, and was also on the periphery of the Justice Party's founding. His trajectory repeatedly alternated between cynicism and comeback. Now, that face is perceived even within his own camp as 'someone who doesn't exercise restraint.' The structure where someone who declared they wouldn't do politics continues to produce political statements seems to overlap with suspicions about his wealth. There is no data to distinguish whether the reason he isn't entering politics is conviction or assets, other than himself.
It's not strange that many critics are concerned about his remarks. What is strange is that this concern no longer comes only from the opposing side. Authority outside of public office is maintained solely by words, without public disclosure of assets, electoral responsibility, or the constraints of party doctrine. Even if those words are wrong, the cost is borne not by him, but by those who listen. This was the case for investors who suffered losses from ShillaJen, and this autumn, it is happening to his supporters who took his words as fact. Suspicion is not a judgment. However, it is the only public record left for someone who refused to explain.
