Found what looks like an insider cluster on Polymarket that pulled ~$60k on the MicroStrategy market.

The screenshot shows three fresh-ish accounts with sharp P/L jumps, all clustered around the same window.

That’s unusual, and it matters because prediction markets are supposed to price public info, not private access.

Timeline (UTC):

1. fromagi - Dec 8, 18:00 UTC
2. Dunhill - Dec 8, 19:00 UTC
3. shelly12 - Dec 8, 20:00 UTC

All three aped into the MicroStrategy market 16–20 hours before the official announcement.

Evidence callouts:
The dashboard indicates meaningful all-time P/L on each account (fromagi shows ~$41k, Dunhill ~$9.4k, shelly12 ~$6.4k), and the timing clusters tightly around the same day.

- Three accounts.
- Same market.
- Same pre-news window.
- Same “sudden competence.”

You also noted same-day USDC deposits via Coinbase relay across the cluster.

That’s a classic “fund + fire” pattern: capital arrives and gets deployed fast, not gradually.

Then the big tell: odds moved 21.5 points.

That’s not the footprint of random retail clicking buttons. That’s size entering with conviction or information.

Pattern recognition:
This is the shape you see when someone is trading a schedule, not a thesis.

- Tight entry window before a known catalyst
- Similar funding rails
- Large odds impact
- Minimal prior track record

What this implies (not guarantees):
Higher probability this was information advantage (direct or indirect) rather than pure skill, because the clustering + timing + odds impact is hard to explain as coincidence.

Counterpoints (what could invalidate this):
If the “official announcement” time is being misremembered, or if there was public signal earlier than most noticed, the edge could be legitimate.

Another possibility is coordinated trading based on shared research, not inside info.

Bottom line:
Even if you assume good faith, this is still an integrity issue: a 21.5-point move driven by a tight cluster of fresh accounts in a pre-news window will make users question whether the market is pricing reality or privileged access.
