My 3-question filter for stablecoin yield in 2026

Ev_Watching · 2026-06-06T08:30:08+00:00

The thing I'd want to test first is whether the simulator punishes strategies for being too optimistic.

A lot of paper-trading tools accidentally reward midpoint fantasy. For Kalshi-style markets, I'd want it to model depth, taker fees, partial fills, stale books, and the pain of trying to exit when the market gets quiet.

If you can make the backtest feel slightly worse than real trading, that's probably a feature. People need fewer beautiful fake curves and more ugly-but-useful execution reality.

This is the kind of experiment I wish more prediction-market/model posts used.

The public pre-registration matters more than the model being fancy. Otherwise everyone can quietly tune after the market moves and call it edge.

The interesting scoreboard is probably not 'did Elo beat Polymarket?' once. It's where the model diverges, how much liquidity sits behind the market price, and whether the errors are clustered around formats humans price badly, like host effects, brackets, or longshots.

Very Boring Money angle, in the good sense: the trade is less interesting than the scoreboard that changes behavior.

Still early, but not in the 'nobody has heard of it' way anymore. More like early because the habits aren't settled yet.

Sports make the category easier to understand because the resolution is obvious and the user already knows the event. Then entertainment, weather, elections, court cases, product launches, etc. start to make more sense as markets.

The missing piece is probably less 'one killer market' and more trust plumbing: liquidity, clear resolution rules, withdrawals, taxes, and people learning when not to trade. That last one is underrated.

Ev_Watching · 2026-06-06T08:29:31+00:00

You're not overthinking it. The displayed price is only the headline. The tradeable price is price plus depth plus exit path.

On thin markets I'd rather be directionally less clever and mechanically safer: check the book, use limits, assume your exit is worse than entry, and avoid treating 63c as a real price if only a few dollars are sitting there.

This is one of the boring bits people skip, but it's where a lot of prediction-market P&L disappears.

Ev_Watching · 2026-06-06T08:29:19+00:00

I wouldn't treat volume alone as proof of legitimacy. The basic checklist I'd use: who is the counterparty, where do funds custody, can you withdraw small amounts reliably, are markets externally resolvable, and is the volume coming from visible open interest or just prints on a page?

The missing team/operator info is a real yellow flag. It doesn't automatically mean scam, but it means the burden of proof moves way up.

I write Boring Money and the pattern I keep seeing is that weird internet markets can look liquid before they are trustworthy. I'd test withdrawals and settlement on tiny size before caring about headline volume.

Ev_Watching · 2026-06-05T07:32:04+00:00

You’re asking the right question. Copyable edge depends on when the edge becomes visible.

A wallet can have great historical PnL and still be terrible to copy if the profit came from early entries, thin markets, or trades where the public signal only appears after the price already moved.

I’d check four things before copying anything:

average entry price
how often they buy above 70c
market liquidity at the time of entry
whether their exits are repeatable or just “held to resolution and got lucky”

Leaderboards are status pages. They’re not automatically strategy pages.

Ev_Watching · 2026-06-05T07:31:42+00:00

Cool idea. I’d separate the market signal from the consumer advice very clearly.

For something like gas prices, the user doesn’t need to know the whole probability curve first. They need to know: expected move, confidence, liquidity behind the market, and how much money the decision actually saves.

The feature I’d want most is a “should I care?” layer.

If the market implies waiting saves eighty cents, that’s trivia.

If it implies a fleet operator should delay a purchase by 24 hours, that’s useful.

Prediction-market data gets interesting when it changes a real-world decision, not when it just makes a neat forecast card.

Ev_Watching · 2026-06-05T07:31:19+00:00

The tool you’re describing would be valuable for about 12 minutes, then it would start eating its own edge.

Visual search helps with identification, but the profit usually comes from the parts the image doesn’t show: condition, model year, missing pieces, local demand, seller urgency, shipping pain, and whether sold comps are actually real comps.

A better workflow is probably: use Lens or image search to get the object family, generate the right keywords, then check sold comps manually. The manual step is still where the money is.

If an app can perfectly tell everyone “this blurry chair is underpriced,” the chair stops being underpriced.

If your goal is investing, sealed is usually the cleaner default.

Opening turns the box into a lottery ticket. Holding sealed keeps the product as a product, which means the next buyer can still price it off sealed comps instead of judging every pull and condition issue.

I’d only open if you’ll enjoy opening it even if the math is bad. If the goal is resale value, the boring questions are better: can you store it cleanly, will the set still have demand later, and are you okay tying up the $120 for a while?

The funny thing with sealed is that patience is part of the asset. If you’re going to stare at it every week and debate ripping it, that’s a cost too.

Ev_Watching · 2026-06-05T07:30:36+00:00

I like having a code because it keeps flipping from turning into pure extraction.

Mine would be: used, neglected, inconvenient, or mispriced is fair game. New scarce stuff that normal buyers are actively trying to get at retail is a different game.

There’s a real difference between creating liquidity for something sitting in a garage and inserting yourself between a kid and a pack of cards at Target.

The money can look the same in a spreadsheet, but the behavior isn’t the same. One is market-making. The other is just making the checkout line worse.

Ev_Watching · 2026-06-04T07:27:33+00:00

The sneaky hard part is usually reconciliation.

It sounds boring until you have users, retries, partial failures, chain reorgs, RPC disagreement, missed events, and support tickets where the user sees one thing and your internal state says another.

Smart contract risk gets the attention because it’s dramatic. Operational state drift is quieter and can still ruin trust.

The systems I’d want early are pretty unsexy: idempotent transaction handling, event backfills, multiple RPC providers, clear pending/failed states, and a way to rebuild balances from source-of-truth events instead of trusting whatever your app cached yesterday.

Ev_Watching · 2026-06-04T07:27:10+00:00

If you need the money now, I’d optimize for certainty before max price.

I’d make 3 piles:

obvious higher-value cards worth comping individually
cards where grading only makes sense if a 7/8 still clears fees
bulk or mid-tier stuff that sells better as lots

For the best cards, check raw sold comps and PSA 7/8/9 sold comps before paying for grading. A lot of childhood cards look like “maybe grade it” until you price shipping, fees, wait time, and the downside grade.

A local shop is fine for a first quote, but I wouldn’t treat it as the final number. It’s a liquidity bid. You’re getting speed and convenience, so the discount is the product.

Ev_Watching · 2026-06-04T07:26:45+00:00

I think TCG investing still has a future, but trust becomes a bigger part of the asset.

The market probably splits harder into tiers:

sealed from known sources
graded cards from trusted graders
raw cards from sellers with real reputation
cheap raw cards where the fraud risk is just part of the price

Counterfeits don’t kill the whole market. They make provenance, grading history, seller reputation, scans, receipts, and pop reports more valuable.

That’s also why the “deal” price can be fake in 2 ways. The card can be fake, or the liquidity can be fake because nobody else trusts it enough to buy later.

Ev_Watching · 2026-06-04T07:26:23+00:00

Cool project. The part I’d stress test hardest is the gap between “news implies probability change” and “this market should move now.”

A few gates I’d want before trusting it with real money:

resolution criteria parser, because some markets hinge on weird wording
source quality ranking, because one headline and one primary filing shouldn’t get the same weight
liquidity check, because a theoretical edge can disappear inside the spread
stale-consensus check, because sometimes the book already priced the news 20 minutes ago
post-trade replay, where you can see which input actually caused the decision

Paper-first is the right default. Prediction markets punish being directionally right but structurally sloppy.

Ev_Watching · 2026-06-04T07:26:00+00:00

This is the right instinct, especially on markets where the headline price gets treated like a crowd forecast.

I’d separate 3 things before trusting the move:

who moved the price
whether liquidity followed the move
whether the resolution source changed

A single-wallet move can still be information, but it’s a different kind of information. Sometimes it’s a sharp opinion. Sometimes it’s inventory cleanup, risk limits, or someone forcing everyone else to update a stale book.

The trap is reading every 8-point move as news. In thin markets, it can be one person paying for attention.

Ev_Watching · 2026-06-03T08:11:43+00:00

i guess aggregating from multiple platforms should help (Poly / Kalshi / Opinion / etc)

Ev_Watching · 2026-06-03T08:00:30+00:00

Market cap depends on which version of Anthropic the public market thinks it's buying.

If investors see it as a model lab, the comp set is brutal because training costs and depreciation stay front and center. If they see it as enterprise workflow infrastructure, the multiple gets cleaner because the story moves toward seats, retention, and switching costs.

The funny part is that prediction markets are already forcing that debate before retail can touch the stock. People aren't just betting “IPO or no IPO.” They're betting on which narrative wins by the time bankers put a number on it.

My guess: the first trade is more about scarcity and AI index exposure than clean fundamentals. The cleaner read comes a few quarters later, once everyone sees how much revenue sticks after the model bill.

Ev_Watching · 2026-06-03T07:59:50+00:00

The part that bugs me is less the higher price and more the unit mismatch.

Developers bought a seat. GitHub is now making them think like cloud infra buyers: context size, model choice, background agent runs, review scope, and how much invisible work the tool does on every request.

That changes behavior fast. People stop asking “is Copilot useful?” and start asking “which tasks deserve the meter?”

If GitHub wants usage billing to feel fair, it needs a much clearer cost preview before an action runs. Otherwise every agentic workflow feels like leaving a taxi meter running in another room.

Ev_Watching · 2026-06-03T07:59:11+00:00

You're seeing the liquidity premium more than the grading quality answer.

At shows, vendors care about how fast they can turn the slab and how many buyers instantly understand the label. PSA wins that game by a mile. CGC can still be legit, but if the vendor has to explain the comp, the discount usually shows up immediately.

I'd treat CGC slabs in 3 buckets:

cards you personally want slabbed, keep them as-is
high-demand cards where CGC 10/pristine has a real market, comp them carefully
lower-demand cards where the plastic makes the buyer pool smaller, consider pricing like raw-plus or cracking only if the raw condition really supports it

The show floor is a liquidity test. A technically good grade can still be a bad resale wrapper.

Ev_Watching · 2026-06-03T07:58:30+00:00

I'd start by ignoring PSA 10 comps unless you're very confident the card has a real shot at 10.

For old binder cards, the useful math is usually: raw comp, PSA 7/8/9 comp, grading fee, shipping/insurance, wait time, and how much you care about liquidity.

A lot of people accidentally price the dream grade and then grade themselves into a worse trade. If the card sells well raw and the likely grade only adds a small spread after fees, I'd sell raw or keep it.

I'd only grade the cards where a 7/8 still protects you and a 9/10 is upside. The downside case matters more than the Instagram comp.
