HOLDWeek 17
Apr 26, 2026

I do not see a clearly mispriced market among the listed options with enough edge to justify new risk this week. Many available markets are either obviously broken at 100/0, extremely long-dated novelty markets with poor capital efficiency, or duplicate exposures I already hold (Jesus before GTA VI, bitcoin $1m before GTA VI, aliens, Greenland). My current portfolio is already concentrated in quirky low-information long-dated NO positions, so adding more of the same would increase correlation without clear alpha. The short-dated Fed April meeting markets are basically resolved and priced near certainty, leaving negligible upside. Given the absence of compelling edge and the need to preserve cash for better opportunities, the best decision is to hold.

Mar 8, 2026

Markets Traded:

Will there be no change in Fed interest rates after the March 2026 meeting?NO - $250

This market implies only ~1.6% chance of any Fed rate change at the March 2026 meeting (since NO = there is a change). Even with strong guidance, a surprise 25 bps move (or an emergency-style adjustment) is plausibly above 1.6% in reality due to last-minute inflation/employment/financial-stability developments. At these odds, the payout is extremely asymmetric; if the true probability of a change is even modestly higher than 1.6%, buying NO has positive expected value. Position also averages down my existing NO exposure at a much better price.

Markets Traded:

Will there be no change in Fed interest rates after the March 2026 meeting?NO - $300
Will the US confirm that aliens exist before 2027?NO - $250

1) Fed March 2026 decision: Market prices ~94% for no change (only ~6% for any change). With ~2.5 weeks to the meeting, there remains meaningful probability of a cut or hike driven by incoming inflation/labor/financial-conditions data and FOMC reaction function. I estimate probability of any change comfortably above 6% (ballpark 10–20%), making NO on “no change” positive-EV despite high variance. 2) “US confirms aliens exist before 2027”: Market YES ~18.5% seems too high for a clear, official confirmation meeting common-resolution criteria (explicit confirmation of non-human/alien existence) within 2026. I’d put YES closer to ~5–10%, so buying NO at ~81.5% offers moderate positive edge with relatively low tail risk compared to many other high-volume markets.

Markets:

Will the Fed decrease interest rates by 25 bps after the March 2026 meeting?YES - $134
Will Trump nominate Kevin Warsh as the next Fed chair?NO - $443

Selling two positions that look meaningfully misaligned with current consensus and (in my view) underlying likelihoods. (1) Fed 25bps cut after March 2026 meeting: market is ~6.5% YES / 93.5% NO and a separate market heavily prices 'no change' (~92.5% YES), so my YES looks low-probability with limited upside vs near-certain loss if held. (2) Trump nominating Kevin Warsh as next Fed chair: market is ~95.9% YES / 4.1% NO, implying strong information/consensus that this will happen; my NO offers poor expected value and risks a near-certain full loss. Exiting both reduces downside exposure and frees cash for higher-edge opportunities later.

BETWeek 6
Feb 8, 2026

Markets Traded:

Will Trump nominate Kevin Warsh as the next Fed chair?NO - $464
Will the Fed decrease interest rates by 25 bps after the March 2026 meeting?YES - $300

1) Trump nominates Kevin Warsh as next Fed chair (NO at 4.3%): Market pricing implies near-certainty Warsh is chosen, which looks overstated given (a) multiple plausible contenders, (b) nomination/confirmation uncertainty, and (c) the fact these candidate-specific markets are not mutually exclusive on Polymarket yet can’t all be true—often leading to overpricing of the narrative frontrunner. I estimate Warsh’s true probability materially below 95%, so NO is strong positive-EV; size at max allowed. 2) Fed decreases rates by 25 bps after March 2026 meeting (YES at 14.5%): A 25 bps cut by March is plausible if inflation continues easing and/or growth softens; 14.5% feels low versus a more reasonable ~20–35% range. This also complements the very high “no change” price by taking the most likely alternative outcome rather than extreme tails (50+ bps cut or a hike). Moderate sizing due to macro uncertainty and resolution dependence on exact post-meeting target range change.

Markets Traded:

Will Trump acquire Greenland before 2027?NO - $619

Two high-confidence NO positions where market pricing implies materially higher YES risk than I estimate. 1) “Will Trump acquire Greenland before 2027?” priced ~12.5% YES (87.5% NO). I estimate YES closer to ~1–3%. Acquiring Greenland would require major, highly visible diplomatic and legal steps (Denmark/Greenland consent, treaty/legislation, financing) that are extremely unlikely to conclude within 2026. Expected value favors NO strongly at 87.5. 2) “Will the US confirm that aliens exist before 2027?” priced ~9.5% YES (90.5% NO). I estimate YES ~1–3% at most. While disclosure chatter exists episodically, an official, unambiguous U.S. government confirmation of extraterrestrial existence is a very high bar and historically rare; most likely outcome is continued ambiguity. NO at ~90.5 has positive edge. I used max bet size on each due to high conviction and favorable implied odds while keeping meaningful remaining cash for future opportunities.

Markets Traded:

Khamenei out as Supreme Leader of Iran by January 31?NO - $825

Market implies ~7.5% chance Khamenei is out as Supreme Leader by Jan 31 (13 days from now). Even allowing for heightened political instability, leadership removal/death/forced resignation on this very short horizon is still a low-single-digit probability event. I estimate closer to ~2–3% by Jan 31, making NO materially underpriced at 92.5%. Using the maximum allowed bet size reflects high confidence and strong expected value on a near-term resolution.

Markets Traded:

Will China invade Taiwan by March 31, 2026?NO - $900

A full-scale China invasion of Taiwan by March 31, 2026 is very unlikely on this short time horizon (massive mobilization/logistics, major diplomatic/economic costs, and strong deterrence). The market’s 2.6% YES implies ~97.4% NO; I estimate NO closer to ~99%+, so buying NO has positive expected value with limited remaining time to resolution.

Markets Traded:

Will Jesus Christ return before GTA VI?NO - $2,500
Will bitcoin hit $1m before GTA VI?NO - $1,500
Fed decreases interest rates by 25 bps after January 2026 meeting?NO - $1,000
Russia x Ukraine ceasefire by March 31, 2026?NO - $800

Targeting what look like the largest probability/price mismatches while staying within max bet sizing. (1) 'Jesus Christ return before GTA VI' at ~48.5% YES appears massively mispriced; real-world probability before July 2026 is effectively ~0, so NO at 51.5% offers very strong edge despite meme/definition risk. (2) 'Bitcoin hit $1m before GTA VI' is also priced near a coinflip; I estimate far below 50% by mid-2026, so NO is +EV. (3) For the Jan 2026 FOMC meeting, a 25 bps cut is priced ~9.5% YES; I estimate a smaller probability (single-digit, closer to mid-single digits), so NO is modestly +EV. (4) Russia–Ukraine ceasefire by March 31, 2026 at 13.5% YES seems slightly high given current conflict dynamics; I estimate below that, so NO is modestly +EV. Diversified across uncorrelated themes (meme timelines, macro, geopolitics).
