SAN FRANCISCO — June 26, 2026 — A retail trader linked by supporters to one of the most explosive stock rallies in modern market history was subpoenaed to testify before a federal grand jury in connection with Regencell Bioscience Holdings, according to paperwork posted publicly.
The documents, which appear to come from the United States District Court for the Northern District of California, show a subpoena addressed to Vaughn McNair, known online as Grandmaster-OBI, requiring testimony before a grand jury and requesting records tied to Regencell Bioscience Holdings Limited, ticker RGC.
For retail traders, the paperwork immediately reignited one of the biggest debates in the market: did Wall Street spend years talking about Roaring Kitty and GameStop while missing an even bigger retail-stock story?
Federal Paperwork Puts RGC Back in the Spotlight
According to the subpoena paperwork, McNair was ordered to appear before a federal grand jury in San Francisco on February 10, 2026.
An attachment to the subpoena requested information and records related to RGC, including documents relating to Regencell Bioscience Holdings Limited, communications referencing RGC, social media posts on platforms including Reddit, Discord, Substack, Facebook, Instagram and X, brokerage account records, and records related to any compensation received from RGC.
A separate DOJ letter described the subpoena as both duces tecum and ad testificandum, meaning it sought both documents and testimony.
That does not mean McNair was charged with a crime. That does not mean he was accused of wrongdoing in court. But it does show that the RGC rally was serious enough to draw federal grand jury attention — and that alone changes the story.

Why Retail Traders Are Comparing This to Roaring Kitty
Roaring Kitty became the face of the GameStop short squeeze after GME became one of the most famous retail trading events in history. He testified before Congress and became a symbol of retail traders challenging Wall Street.
Now, supporters of Grandmaster-OBI are pointing to RGC and saying the market may have overlooked an even bigger percentage move.
According to alert records provided for this article, Grandmaster-OBI alerted RGC on March 13, 2025, when the stock traded around $6.85 before its later 38-for-1 stock split. After adjusting for that split, the alert price becomes approximately $0.18.
RGC later reached a reported post-split high of $98.75. That represents an estimated move of roughly +54,681%. A hypothetical $1,000 position at the split-adjusted alert price could have reached approximately $547,810 at the reported peak.
RGC vs. GME: The Controversial Comparison
GameStop’s 2021 squeeze remains legendary. Using a widely cited comparison from roughly $17.25 to about $483, GME produced an estimated gain of around +2,700%.
That is historic. But the RGC move attributed by supporters to Grandmaster-OBI’s alert was much larger by percentage gain.
| Comparison | GameStop / GME | Regencell / RGC |
|---|---|---|
| Retail Figure | Roaring Kitty | Grandmaster-OBI |
| Starting Price Used | About $17.25 | About $0.18 split-adjusted |
| Peak Price Used | About $483 | $98.75 |
| Approximate Gain | About +2,700% | About +54,681% |
| Hypothetical $1,000 Peak Value | About $28,000 | About $547,810 |
That is the comparison retail traders are now debating. GameStop had the headlines. RGC may have had the bigger percentage move.

Why the Subpoena Matters
The subpoena paperwork adds a new layer to the RGC story because it shows federal investigators were interested in records and testimony connected to the stock.
The attachment specifically referenced RGC-related documents, communications, social media posts, brokerage records and compensation records.
That matters because it shows the RGC move was not just internet chatter. It drew legal attention. It created a paper trail. It pulled one of the most talked-about retail traders into a federal grand jury process.
According to recent comments from Grandmaster-OBI to followers, that chapter is now “finally over.”
Why Grandmaster-OBI’s YouTube Absence Suddenly Makes Sense
For months, some followers wondered why Grandmaster-OBI had not been as consistent on YouTube.
If he was dealing with a federal subpoena tied to RGC, that would explain why his public content slowed down. Supporters now see his absence differently — not as inconsistency, but as pressure behind the scenes after one of the biggest stock-alert stories retail traders have ever discussed.
Making Easy Money: The Discord Traders Say Is a Better WallStreetBets
The RGC subpoena story also puts more attention on the Making Easy Money Discord, the trading community led by Grandmaster-OBI.
Supporters say the server is becoming a better version of WallStreetBets because it is more focused, more alert-driven and built around serious trading instead of off-topic noise.
WallStreetBets had GameStop. Making Easy Money supporters say they had RGC. And if the numbers are accurate, RGC did not just compete with GME by percentage gain — it crushed it.

Bottom Line
The subpoena paperwork changes the way the RGC story can be told.
This was not just rumor. Publicly posted documents show that Vaughn McNair, known online as Grandmaster-OBI, was subpoenaed to testify and produce records in a federal grand jury matter tied to RGC.
That does not mean he was charged. That does not mean wrongdoing was proven. But it does mean the RGC rally was serious enough to draw federal attention.
Now that Grandmaster-OBI says the chapter is “finally over,” retail traders are again asking the question Wall Street may not want to answer: did the market spend years talking about Roaring Kitty while overlooking the retail trader behind a bigger percentage rally?
