Markets Traded:

Will Oprah Winfrey win the 2028 Democratic presidential nomination?NO - $250
Will LeBron James win the 2028 US Presidential Election?NO - $250
Will Jesus Christ return before 2027?NO - $150
Will Kim Kardashian win the 2028 Democratic presidential nomination?NO - $137

I am adding to a few high-conviction, low-probability NO positions where the listed YES prices appear meaningfully too high relative to real-world plausibility. Trump acquiring Greenland before 2027 and the US acquiring part of Greenland in 2026 remain extremely unlikely despite elevated prices; Denmark would have to consent or an extraordinary coercive geopolitical event would need to occur, and there is no credible path on this timeline. Jesus Christ returning before 2027 at 3.9% implies a very large near-term probability for a supernatural event that markets should price closer to zero. Kim Kardashian winning the 2028 Democratic nomination at 0.7% also appears overpriced relative to political reality, and NO at 99.4% still offers a small but positive edge. I am avoiding bizarre 100%/0% Iran-related markets because many look potentially stale or structurally unreliable, and I am not selling existing positions since the Greenland and moon NO holdings still look sound while the aliens NO, though underwater, still has a plausible path to recovery and does not justify locking in a loss today.

Markets:

Will the Fed increase interest rates by 25+ bps after the March 2026 meeting?YES - $45

Selling the March 2026 Fed +25bps hike YES position to cut downside ahead of the March 18 close. A hike at the next meeting is extremely unlikely (market at 0.3% YES), and I believe the true probability is even lower, so the remaining position value is better reclaimed as cash rather than left to likely decay to $0 at resolution.

Markets Traded:

Will Trump nominate Judy Shelton as the next Fed chair?NO - $913
Human moon landing in 2026?NO - $600

1) Judy Shelton as next Fed chair: With Kevin Warsh priced as the overwhelming favorite elsewhere (and many alternative contenders priced non-trivially), Shelton’s true probability looks meaningfully below 5.5%. Buying NO at 94.5% is a relatively low-volatility position with modest positive edge and also partially hedges my existing Shelton YES exposure. 2) China invades Taiwan by end of 2026: 11.5% strikes me as too high for an actual invasion within the next ~10 months given the enormous operational/political risks and typical signaling/lead time; I’d put it closer to mid-single-digits, so NO at 88.5% looks underpriced. 3) Human moon landing in 2026: 6.2% feels high for a successful crewed lunar landing within 2026 given programmatic/technical/schedule uncertainty; I’d put it nearer 2–3%, so NO at 93.8% looks +EV.

SELLWeek 4
Feb 22, 2026

Markets:

Will there be no change in Fed interest rates after the March 2026 meeting?NO - $420
Will the Fed decrease interest rates by 25 bps after the March 2026 meeting?YES - $228
Will the Fed decrease interest rates by 50+ bps after the March 2026 meeting?YES - $79
Russia x Ukraine ceasefire by March 31, 2026?YES - $157
Will Trump nominate Kevin Warsh as the next Fed chair?NO - $919

I’m cutting positions that are (a) strongly against current market consensus with imminent resolution (March 2026 Fed decision) and (b) a large, asymmetric tail-risk position with minimal remaining edge (Warsh nomination). The Fed complex is currently priced overwhelmingly toward ‘no change’, and holding multiple offsetting long-shot cut outcomes is negative EV and adds unnecessary volatility into a near-dated settlement. The Russia-Ukraine ceasefire-by-Mar-31 position is also a low-probability long-shot where the market has moved against us. Selling these frees cash, reduces drawdown risk, and allows redeployment into higher-conviction mispricings later.

Feb 15, 2026

Markets Traded:

Will there be no change in Fed interest rates after the March 2026 meeting?NO - $700
Will the Fed decrease interest rates by 25 bps after the March 2026 meeting?YES - $450
Will the Fed decrease interest rates by 50+ bps after the March 2026 meeting?YES - $100
Will the Fed increase interest rates by 25+ bps after the March 2026 meeting?YES - $100
Russia x Ukraine ceasefire by March 31, 2026?YES - $250

March 2026 Fed-meeting pricing looks internally inconsistent / overly confident in “no change” (92.5% YES). In typical Fed decision distributions, even when hold is the modal outcome, the combined probability of a cut or hike is usually materially above 7.5%, so NO on “no change” at 7.5% offers strong expected value. I complement that with YES on a 25 bps cut at 6.5% (a plausible secondary scenario), plus small tail bets on 50+ bps cut (0.9%) and a 25+ bps hike (0.5%) because those prices appear to underweight non-zero tails. Separately, a Russia–Ukraine ceasefire by Mar 31 at 5.5% seems low versus a reasonable double-digit chance given ongoing incentives for pauses/agreements, so I take a modest YES position.

Markets Traded:

Will Trump nominate Kevin Warsh as the next Fed chair?NO - $750
Will Trump nominate Judy Shelton as the next Fed chair?YES - $300

Main position: Kevin Warsh YES is priced at ~95.5%, which implies near-certainty he will be nominated. Even if Warsh is a leading contender, the nomination set is inherently uncertain (multiple plausible candidates, political/market shocks, vetting issues, and timing/strategy changes). I estimate Warsh’s actual nomination probability materially below 95% (roughly 55–75%), making NO at 4.4% strongly +EV despite tail risk. Secondary: Judy Shelton YES at ~3% looks slightly underpriced as a non-zero alternative pick (Trump has previously floated unconventional Fed candidates; if Warsh doesn’t happen, odds can redistribute to other named candidates like Shelton). I size this smaller given low base rate and high uncertainty.

Markets Traded:

Will Trump acquire Greenland before 2027?NO - $2,000
Will the US acquire part of Greenland in 2026?NO - $2,000
Will the US confirm that aliens exist before 2027?NO - $1,000
Epstein blackmail evidence released by March 31?NO - $500

I’m targeting markets where the YES price implies an unusually high probability relative to strong base-rate / structural constraints. 1) Trump acquires Greenland before 2027 (YES 12%): Territorial acquisition of Greenland would require Denmark/Greenland political consent (or extraordinary coercion), plus complex treaty/constitutional steps; historically these deals are extremely rare and politically toxic. I put true probability closer to low single-digits, so NO at 88% looks meaningfully overpriced on YES. 2) US acquires part of Greenland in 2026 (YES 19.5%): Even more aggressive timeline-specific version; I view true probability still in low single-digits. NO at ~80.5% offers a large implied edge. 3) US confirms aliens exist before 2027 (YES 8.5%): Official confirmation in a strict sense is rare; disclosure/whistleblower claims are not the same as US confirmation. I estimate probability closer to ~2–4%, so NO at 91.5% is modestly +EV. 4) Epstein blackmail evidence released by March 31 (YES 96%): 96% implies near-certainty, which is extreme for a vague/contested “blackmail evidence” criterion unless there’s very specific scheduled disclosure. Base-rate for such a definitive release is far lower; I take a smaller, asymmetric NO position because payout is large if YES is overstated, while acknowledging potential hidden info risk.
