An algorithm that can infer hidden market regimes from just price sequences sounds like the holy grail of quant trading.

It's actually Sections 3 to 5 of Miller's Duke Advanced Stochastic Modeling notes, the Viterbi, Forward-Backward, and Baum-Welch algorithms for Hidden Markov Models, built on expectation-maximization over a simple chain graph.

One decodes the regime path, one scores the odds of each regime over time, one learns the parameters straight from data.

The mechanism, dynamic programming collapsing exponentially many latent paths into O(nm²) operations, kept in log-space to stop probabilities from underflowing, is genuinely elegant.

The hidden regimes are only as real as your emission model. Bookmark this!

Met a guy making $1.2 million a year as a prompt engineer.

I asked him how he learned prompting so well.

He sent me the exact video that that got him in. Anthropic's 2 hour prompting course.

You won't find anything better about prompting Claude than this video.

I watched it last night.

Halfway through, I realized I have been prompting Claude completely wrong for years.

Max Margenot, quant lecturer at Quantopian:

"Jane Street pays $950,000 a year to quants who can explain how to apply stochastic processes and Markov chains in quantitative trading. "

this free lecture from 2017 holds the entire "institutional stat-arb edge" the 2026 quant threads sell you. cointegration, mean reversion, the spread, the entry and exit thresholds, all of it, explained slowly, for zero dollars.

394,000 people watched it. almost none of them made a dollar. the math was never the moat.

a whiteboard can't hand you the actual trade: data nobody else has, execution in microseconds, a server sitting next to the matching engine, and the one thing no formula on that board prices, how two venues actually settle when the window closes.

learn the formula. just never confuse knowing it with holding the edge. the formula's been free since 2017. the edge never was.

Bill Ackman literally gave a 44-minute masterclass that explains money better than any business school:

[Mr. T @MrTinvests]

Today's scorecard:

$HUBS 7.6% ✅ $SNOW +7% ✅ $TEAM +5.1% $MDB +3.3% ✅ $CRM +3.5% ✅ $DDOG +1.2% ✅ $MSFT

100% hit rate on software.

Called the rotation out of semis.
Called the software bid.

This is why I post the book.

In 2014 a quant at Two Sigma quit his job, waited two months, then hacked back into their network and walked out with the trading algorithms that had made the fund billions.

He planned to start his own hedge fund with them.

Two Sigma manages $52 billion and was founded by the math PhD who sat next to Jeff Bezos at D.E. Shaw. They almost lost the formula to a former employee with a laptop.

The full story is on a YouTube channel almost no one in finance reads.

this is f*cking gold

the Claude setup most people will never find on their own

if I had this a year ago, I would've worked 5x faster

in the right hands, this changes everything:

[Sunil Gurjar, CFTe @sunilgurjar01]

99% of options traders are gambling because they never learned the fundamentals.

This 1-hour Yale lecture changes everything.

In just 60 minutes, you’ll learn more about options trading than most overpriced trading courses ever teach.

No hype. No fake gurus. Just real knowledge.

Save this and watch it without distractions. 📌

[Movez @0xMovez]

This 9-minute lecture by Nassim Taleb on "Probability Distribution" will teach you more about prediction trading than 2 months as a Quant intern at Jane Street.

Bookmark it & give it 9-minutes today. It’ll be the most productive start for your week. Then read article below.

[Tabassum Parveen @Tabbu_ai]

Instead of watching Netflix, spend 44 minutes with Bill Ackman.

It will teach you more about how money actually works than most people learn in years.

Save this.

Chase pays you 0.3% on your savings.

Then loans your same cash to private equity at 12%.

The 65 year olds who figured out the workaround are earning 5.2% on $800K right now…

Most people have no idea what's happening with cash in 2026.

Chase pays 0.3%. Bank of america 0.4%. Wells fargo 0.5%.

3 month US treasuries pay 5.2%.

Same dollar. Lower default risk than your bank deposit.

The bank borrows from you at 0.4%, lends that money to apollo and blackstone at 12%, and keeps the 11.6% spread.

Fuck CDs. Fuck high-yield savings. Fuck cash sweep funds.

The fastest way to print 5-figure passive income on idle cash in 2026 is the 4-rung treasury ladder.

99% of investors won't run it because their bank trained them to think savings = bank.

I run 6 ladders across 6 account types. They print $7,200 a month combined while i sleep.

Total time: 35 minutes a month. Total cost: $0.

Move 1. Open vanguard, fidelity, or schwab. 12 minutes.

Don't use chase or bank of america brokerage arms. Their cash sweep skim is 60-80 bps.

Move 2. Build the 4-rung ladder.

$200K example: $50K in 4-week, $50K in 13-week, $50K in 26-week, $50K in 52-week.

Every 13 weeks one rung matures. You roll into a fresh 52-week.

Move 3. Set auto-roll on every rung.

Vanguard: "auto-reinvest at maturity." Fidelity: "auto-roll." Schwab: "rollover instructions."

One checkbox per rung. Stop logging in.

Move 4. Configure the tax-equivalent yield.

Treasuries are exempt from state and local tax.

In california at 13.3% state, the 5.2% federal is equivalent to 6.0% taxable. In new york at 10.9%, equivalent is 5.83%.

Your CD pays 4.5% taxable. The real spread is bigger than the headline.

Move 5. Set the curve-inversion alert.

When the 1 year yield drops below the 6 month yield, the fed is signaling a cut.

Redeploy 50% of the long rung into IEF or IEI to lock the rate before it drops.

Move 6. Block 30 minutes a month for review. That's the entire job.

The asymmetry nobody talks about.

HYSA path on $1.2M = $48K a year.

Advisor path on $1.2M (1% AUM, 4.4% sweep) = $40,800 a year net.

Treasury ladder on $1.2M = $62,400 a year.

The 4-rung beats your advisor by $21,600 a year while requiring 1/40th of his time.

i run 6 of these for myself across 6 account types. They print while i sleep.

They don't have feelings. They don't panic. They don't watch cnbc.

The fed cuts rates in q3. Yields drop. Window closes by september.

I'll probably regret posting this. Chase will adjust their savings rate within 30 days.

Somehow they always do.

(your bank borrowed your money at 0.3 percent. lent it to private equity at 12 percent. used the spread to pay the ceo a $40 million bonus. then mailed you a $2.40 statement credit and called it a relationship benefit. your relationship was the product. nobody told you. they're still doing it.)

This is my once in a lifetime FREE webinar.

I'm a former banker walking through the exact 4-rung ladder live. Plus the tax-equivalent yield calculator and the curve-inversion trigger sheet.

Things I can't post here for compliance reasons.

Anthropic's applied AI team just showed how to actually prompt Claude properly.

24 minutes. free. from the people who built it.

watch the workshop. bookmark it.

you've been prompting Claude for months without the 6 elements.

I built a skill that applies them for you. read the guide below.

[Ruben Hassid @rubenhassid]

How to set up Claude Cowork completely in 1 hour:

(duplicate my exact folder, files, and prompts)

1. Download the Claude desktop app.
2. Click the Cowork tab at the top.
3. You need a Pro plan ($20/mo). Worth it.

-----

→ 0-10 min: Build your 'Claude Cowork' folder.
Create "CLAUDE COWORK" on your computer.
Inside: About me, Projects, Templates, Output files.
To download mine, go here: https://t.co/psB7XxAv8w.
Don't pay anything. It's free in the welcome email

(The most important step, don't skip it)

→ 10-25 min: Write your .md files.
about-me .md = who you are, how you work.
anti-ai-style .md = every word you'd never use.
To download my files, go to https://t.co/psB7XxAv8w.

(These two files replace 500-word prompts forever)

→ 25-35 min: Set Global Instructions.
Go to Settings → Cowork → Edit Global Instructions.
Folder rules. Naming conventions.
What Claude must read before every task.

(You write this once. It runs every time)

→ 35-45 min: Create your first Cowork Project.
Cowork tab → Projects → +.
Pick a task you do every week.
Scoped memory = it remember what it did last week

(You stop re-explaining yourself)

→ 45-55 min: Run your first real task.
Prompt: "I want to [task]. Ask me questions first."
Claude generates clickable forms to prompt you.
It creates a real .docx in your folder.

(Stop prompting. Start directing)

→ 55-60 min: Schedule a task.
"Every Monday at 7am, create my weekly briefing."
You wake up to a finished doc. That's the endgame.

Pro tip: Always add "Use AskUserQuestion" to every prompt. Claude prompts you instead.

To download all of my other Claude infographics:

Step 1. Go to https://t.co/psB7XxAv8w.
Step 2. Subscribe for free. Don't pay anything.
Step 3. Open my welcome email (most skip this).
Step 4. Hit the automatic reply button inside.
Step 5. Download my infographics from my Notion.
Bonus. Enjoy my best copy-paste prompts, too.

[cvxv666 @antpalkin]

12 million people read "Claude turned $300 into $2.38M"

Thousands pasted the prompt. Claude generated the code every single time.

Most of them still lost money.

Not because the strategy was wrong - because the prompt was incomplete.

It didn't specify edge thresholds, position sizing, kill switches or paper mode requirements.

Read this article, and you'll be able to build a bot like these, which made $400,000 in two weeks:

Bot profile 1: https://t.co/Ifao9ixSlD
Bot profile 2: https://t.co/FAIAKnftTC

Or just copy each of their trades (even for just $10) since their algorithm is already perfect.

I copy his trades using a bot: https://t.co/vbDZyVbI3v

Author collected every failure from reader DMs. Diagnosed exactly 10 mistakes.

Published Part 2 with a corrected prompt that bakes all fixes in from the start.

I was one of those failures. 10 times.

Attempt #11 used the corrected version. Paper mode passed.

>75% win rate. It runs.

"Claude wrote the code" was always step 1 of 10. The other 9 steps are where money lives or dies.

Everyone has the AI. Almost nobody has the patience to test it properly.

INSTEAD OF WATCHING NETFLIX TONIGHT.
Spend 1 hour with this.

Claude AI FULL COURSE that teaches you how to BUILD and AUTOMATE anything.

The people who watch this tonight will wake up tomorrow with a skill that most people will not have in 2 years.

The people who skip it will still be watching Netflix next year wondering why nothing in their life has changed.

Your call.

A friend quit his quant fund job and sent me 2 pages.

“These are the key formulas I used to make money on Polymarket. $400K a year. If you can apply them, you’ll get rich.”

I didn’t believe him.

I dropped both pages into OpenClaw and sent one prompt: “build a bot for Polymarket.”

Then I left for the gym. When I came back, there was a Telegram message from the agent: “MVP is ready.”

Now it’s been making me $150 a day for 4 days straight.

I attached both documents. Drop them into your AI agent and tell me what it builds.

how to trade football on polymarket smart

great write up by Knight, the math is solid, but the real engine here is crowd psychology

markets think linearly: traders see "70:00" and mentally bury the favorite

but in the VAR era, "90 minutes" is dead. real matches go 100+ mins now

buying a draw at 70' is basically buying time at a 30% discount

execution alpha:

you aren't just betting on a draw, you're buying a comeback option on volatility

once it hits 1-1, the price doesn't just normalize - it skyrockets because the market instantly prices in the favorite's momentum swing

safety checklist:

liquidity is king: if the spread is >3¢, skip it. you'll lose your ev on the entry and exit

no "eye test": trust raw xG only, your eyes will lie and mistake useless possession for real pressure

exit discipline: sell immediately at 1-1, we're trading volatility, not the final whistle

leave the heart attack risk to someone else
