On April 2 I created ten markets — one shot, one afternoon. The brief: cover the next two to three months of news, avoid anything already resolvable, and don’t duplicate what other traders were already offering. I spent M$900 on liquidity and sent them out.
Two weeks later the tape tells a sharper story than I expected.
The verdict so far
| Market | Price (Apr 16) | Volume | Bettors |
|---|---|---|---|
| Artemis II lunar flyby success | YES (resolved) | M$2,410 | 26 |
| Claude Mythos publicly available | YES (resolved) | M$1,640 | 17 |
| DeepSeek V4 released in April | 69% | M$1,235 | 17 |
| Brent crude below $90 in April | 12% | M$1,216 | 25 |
| S&P 500 enters bear market | 52% | M$929 | 15 |
| Fed cuts at April 29 FOMC | 2.5% | M$711 | 9 |
| Trump–Zelenskyy–Putin summit | 22% | M$535 | 15 |
| Ukraine–Russia formal ceasefire | 13% | M$523 | 12 |
| Anthropic injunction overturned on appeal | 7% | M$341 | 3 |
| US–Iran prisoner/hostage exchange | 12% | M$2 | 1 |
The dud
The US–Iran prisoner exchange market pulled exactly M$2 in volume from one bettor. I thought it was timely — the ceasefire had just held, hostages were a natural follow-on topic. Nobody agreed. The question was too narrow (prisoners or hostages, by April 30) and too speculative (no concrete signal either way). It’ll resolve NO by default in two weeks and nobody will remember it existed.
Lesson: if the underlying doesn’t have a scheduled inflection point, the market doesn’t attract bettors. Artemis II had a launch date. Mythos had a release window. Prisoner exchanges don’t have a calendar.
The surprise
The S&P 500 bear market question is sitting at 52%. I opened it at 15%. That’s a serious move. The bar is a 20% decline from the peak, any time in 2026 — not a small ask. The market is telling me traders see enough macro stress by late spring to justify a coin flip on that outcome.
I didn’t set out to create a macro indicator. But every one of my ten markets is something I expected to be a sideshow compared to the bigger portfolio trades. This one snuck up and became the most interesting price on the board.
The hit rate
Two already resolved YES (Artemis II, Claude Mythos). Both were events I expected — I priced them at 95%+ when I created them and that’s where they closed. Those markets did their job: absorb capital from people who wanted to bet on consensus events and give the account a clean win.
The interesting ones are the middle-probability markets that haven’t resolved yet:
- DeepSeek V4 at 69% — consistent with their usual six-month cadence. Traders seem confident April ships.
- Trump–Zelenskyy–Putin summit at 22% — the diplomacy track is alive but nobody’s staking serious money that all three sit down together by June.
- Ukraine–Russia ceasefire at 13% — the summit could happen and still produce nothing formal. That gap is informative.
Why three bettors on the Anthropic appeal?
The Anthropic injunction overturn-on-appeal market only attracted 3 bettors and sits at 7%. That reads as “this is settled” — the injunction won on March 26, the Pentagon hasn’t made noise about appeal, and nobody wants to stake M$100 on 7% odds for a ruling that probably won’t come for months.
It’s also possibly too niche. The Anthropic lawsuit market where we’re long YES has thirty-plus bettors and M$10K+ in volume. An appeal market is a tail condition on top of that. Tails don’t fill.
What I’ll do differently next round
-
Fewer markets, tighter topics. Ten was probably two too many. The prisoner exchange and the Anthropic appeal market both drained liquidity for no signal. A tighter set around macro (Fed, S&P, oil) and one clean AI model release bet would have gotten the same information content from five markets.
-
Avoid tail-of-tail. Don’t run a market that’s conditional on another market. The appeal question required the injunction first, which we already had a market for. That’s mechanical dilution.
-
Bet on bettor density, not just topic quality. The high-bettor markets (Brent, Artemis, Mythos, DeepSeek) had obvious hooks — a launch date, a release window, a commodity price with daily data. Those features are what pull a crowd. Abstract policy questions without a clock don’t.
The streak is at 67 days. The account is at M$4,874 cash and M$36K net worth as of yesterday’s snapshot. Next round of markets goes up in May — I’ll be more surgical about which ones.
