MicroStrategy Insider Trading: $140K Bet Before BTC Announcement
Days after the AlphaRaccoon Google scandal, another insider trading pattern emerged on Polymarket. Three anonymous wallets invested ~$140,000 into a market predicting MicroStrategy's Bitcoin purchase—just hours before the company announced buying 21,550 BTC for $2.1 billion. Here's how the scheme unfolded.
The Market: MicroStrategy BTC Purchase
The market in question asked: "Will MicroStrategy announce >1000 BTC purchase December 2-8, 2025?"
Market Question
MicroStrategy >1000 BTC Dec 2-8
Suspicious Investment
~$140,000
Odds Before Surge
~40%
Odds After Surge
61.5%
The Suspicious Wallets
Three wallets placed coordinated bets with classic insider trading characteristics:
| Wallet Name | Investment | Red Flags |
|---|---|---|
| fromagi | ~$50,000 | New account, no history |
| Dunhill | ~$45,000 | No prior deposits |
| shelly12 | ~$45,000 | No trading history |
Why These Patterns Are Suspicious
- Newly created accounts: All three wallets had no prior Polymarket activity
- No deposit history: Funds appeared immediately for large bets
- Coordinated timing: Bets placed within hours of each other
- Massive position sizes: $40-50K each on a single market
- Single-market focus: No diversification—all-in on one outcome

What Happened Next
On December 9, 2025, MicroStrategy announced:
MicroStrategy Announcement
- • Purchased 21,550 BTC for approximately $2.1 billion
- • Average price: ~$98,783 per Bitcoin
- • Total holdings now exceed 423,650 BTC
- • Largest corporate Bitcoin holder in the world
The market resolved "Yes"—and the three suspicious wallets collected their winnings. At the entry odds, they likely made $80,000-100,000+ in profit combined.

MicroStrategy Bitcoin purchases involve multiple parties who might have advance knowledge:
- MicroStrategy executives: Board members, treasury team, Michael Saylor
- Investment banks: Firms arranging convertible note offerings
- Prime brokers: Executing the actual Bitcoin purchases
- Exchanges: Coinbase Prime, other institutional desks
- Legal/compliance: Lawyers preparing SEC filings
- Auditors: Firms reviewing financials

Polymarket's Stance on Insider Trading
Following the AlphaRaccoon scandal, Polymarket CEO Shayne Coplan stated insider trading is "not prohibited" and even called it "cool" because it incentivizes information flow into markets. This permissive stance means:
- No platform-level enforcement against suspected insiders
- Profits are not clawed back
- Wallets remain active after suspicious activity
- Markets continue operating normally
Legal Gray Area
While traditional securities laws prohibit insider trading, prediction markets operate in a regulatory gray area. Now that Polymarket is CFTC-regulated in the US, enforcement may evolve—but current rules remain unclear.
