Sam Altman's chart, in plain language

A 10-part walk through the chart in five movements, from the core self out to the horizon. The essentials stay in view; anything marked with a small arrow folds open for the finer detail. Jump to any part below, or click a planet, house or aspect on the wheel above for the deep dive.

New to birth charts? The thirty-second primer
  • Planets are the what: ten drives every person carries. The Moon is how you feel, Mercury is how you think, Mars is how you act.
  • Signs are the how: the style each drive wears. A Moon in Taurus feels slowly and steadily; a Moon in Aries feels fast and hot.
  • Houses are the where: twelve areas of life, so the same drive plays out at work, at home, or in love depending on which room it sits in.
  • Aspects are the conversations: angles between two planets that make their drives cooperate, argue, or fuse into one force.

Every reading below follows that grammar: planet (what) in sign (how) in house (where). If you only read one section, read the Big Three; everything after it is that story told in finer and finer detail.

The Big Three

The Sun is who you are becoming, the Moon is what you need, the Rising is how you arrive. Read together, they are the working summary of the chart.

Your Sun in Taurus is the core self, your Moon in Taurus is the inner emotional life, and your Leo Rising is how you arrive. Your three pillars run on two elements, which gives you a primary nature with a real counterweight. The mix of earth and fire means you are not all one thing, and the tension between the two is part of what makes you interesting and occasionally divided against yourself. These three together are the spine of the whole chart.

SunTaurus · 9th house

Built from what endures. Steady, sensual, slow to anger and slow to change. The body is the temple, and the temple is not a metaphor. Values are bedrock; stubbornness is the shadow side of staying power. Lesson: holding too tightly is not the same as holding. You come alive at the horizon. Meaning, philosophy, travel and the wider world are where identity is found, and the search itself is central to the work.

MoonTaurus · 10th house

Feeling is steady, sensual and slow. Comfort comes from the body, from familiar textures, from food and routine. Once attached, the attachment is permanent. The shadow is stuckness dressed up as loyalty to the past. Feeling is on public display. The nurturing parent often plays a visible role, the career may carry the emotional theme, and the mood becomes part of the reputation.

ASC
RisingLeo · the doorway

You arrive into the light. The temperature of a space changes when you cross the threshold, whether you intended it or not. People reorganise themselves around your presence. Your chart ruler is Sun, in Taurus in the 9th house: the planet that steers the whole chart, and the first place to look for how your Leo rising actually moves through the world.

Your North Star

The lunar nodes are the chart's North Star: not a trait but a direction. The North Node names the unfamiliar growth you are here to move toward; the South Node is what you are leaving.

North NodeTaurus · 10th house · earth element · 2nd decan

The pull is toward Taurus: steadiness, your own resources, the plain things that sustain you, the body's simple yes. The familiar groove is Scorpio: intensity, entanglement, living on other people's crises. Growth is a calm that needs no storm to feel real.

South NodeScorpio · 4th house

The South Node in Scorpio (4th house) is the opposite shore: the gifts and habits you already over-rely on. It is the comfort zone the chart is asking you to move away from.

Finer detail: the decan and the degree

The decan. The North Node sits in the 2nd decan: the sign filtered through Virgo; its instinct softened and complicated by a second flavour.

Chart Ruler

Because Leo rises, the Sun rules the whole chart. And your ruler is also one of the lights. The chart doubles down: the vehicle you travel in is the same force at your core.

The Sun · chart rulerTaurus · 9th house

You come alive at the horizon. Meaning, philosophy, travel and the wider world are where identity is found, and the search itself is central to the work.

Public Face

The Midheaven is not only career; it is the aura you emit in your zone, what a room senses you are for. The IC, opposite it, is the private root that aura grows from.

MC
MidheavenTaurus · the 10th house

With Taurus on the Midheaven, a room senses steadiness: someone solid, unhurried, trustworthy with what matters. Planets in the 10th (Moon, Mars) amplify that signal.

IC
ICScorpio · the 4th house

With Scorpio on the IC, this is the private root the public aura grows from. The lowest point in the chart. Imum Coeli. The ground beneath the feet. The IC is the point directly opposite the Midheaven. The deepest, most interior, most hidden point in the chart. It marks the cusp of the fourth house. Where the Midheaven describes the public face, the IC describes the private foundation. The home life. The roots. The ground the person stands on when no one is watching. The sign on the IC describes the texture of the inner life. The atmosphere of the childhood home. The deep, unspoken emotional climate that the person carries inside themselves regardless of what is happening on the surface.

Planets & Patterns

The planets are the cast: ten drives, each in a sign that colours it and a house that gives it a stage. Read down the roster, then see the aspects (the lines where one planet is locked in conversation with another) and the larger patterns they form together.

Of the ten planets, the weight falls in earth and fixed signs: substance. Structure. The material world. The energy of form.

The Houses

If the planets are the actors, the houses are the twelve rooms they act in. Each room carries a sign on its door, a ruler that ties it to a planet elsewhere in the chart, and sometimes tenants living inside it. Tap any house to open the full reading: the sign, the ruler chain, and who lives there.

Your Generational Role

Uranus, Neptune and Pluto move so slowly that a whole generation shares each sign. The sign is the era you were born into; the house is your personal assignment within it. This is your generational role: the corner of life where the big shift becomes your job to carry, with a lesson to learn and a gift waiting on the other side of it.

UranusSagittarius · 5th house

where you break from the past. Uranus carries the urge to break free, wake up, and overturn what has gone stale.Why it matters for youYour whole generation shares Uranus in Sagittarius. But in your chart it lands in the 5th house, the house of creativity, romance, play. That is your personal assignment: the one corner of life where this slow, generational force stops being abstract and becomes your job to carry. Your generation is here to break what has gone stale and wire up what comes next. Your personal share of that work is the 5th house: creativity, romance and what you make. That is the corner of life where the era's shift stops being your backdrop and becomes your job to carry.The lessonIn matters of creativity, romance, play, your work is tolerating the instability that real freedom costs, and rebelling toward something rather than only away from it.The giftDo that work, and creativity, romance, play becomes exactly where you offer the world originality, sudden insight, and the nerve to do it differently.

The era you were born into: Uranus in Sagittarius

A generation that upends belief, reinventing meaning, religion and the search for truth.

NeptuneCapricorn · 5th house

where you dream and dissolve. Neptune carries the pull toward the boundless: dream, faith, compassion, and the dissolving of every edge.Why it matters for youYour whole generation shares Neptune in Capricorn. But in your chart it lands in the 5th house, the house of creativity, romance, play. That is your personal assignment: the one corner of life where this slow, generational force stops being abstract and becomes your job to carry. Your generation is here to dissolve the hard old boundaries and let something more imaginative and compassionate through. Your personal share of that work is the 5th house: creativity, romance and what you make. That is the corner of life where the era's shift stops being your backdrop and becomes your job to carry.The lessonIn matters of creativity, romance, play, your work is telling the true vision from the seductive illusion, and staying awake instead of escaping.The giftDo that work, and creativity, romance, play becomes exactly where you offer the world imagination, limitless empathy, and a channel to the transcendent.

The era you were born into: Neptune in Capricorn

An era that dreams of universal structure, the spiritualising of authority, the dissolving of institutions.

PlutoScorpio · 3rd house

where you are remade. Pluto carries the drive to destroy what is finished and regenerate it from the root.Why it matters for youYour whole generation shares Pluto in Scorpio. But in your chart it lands in the 3rd house, the house of mind, words, siblings. That is your personal assignment: the one corner of life where this slow, generational force stops being abstract and becomes your job to carry. Your generation is here to take worn-out structures down to the root and rebuild them from the power that was buried. Your personal share of that work is the 3rd house: how you think, speak and learn. That is the corner of life where the era's shift stops being your backdrop and becomes your job to carry.The lessonIn matters of mind, words, siblings, your work is meeting power and loss without grasping for control, and letting the necessary endings actually happen.The giftDo that work, and mind, words, siblings becomes exactly where you offer the world regenerative depth, unbreakable will, and the power to transform yourself and the people around you.

The era you were born into: Pluto in Scorpio

Pluto is at home here. An era that remakes sex, death, power and the underworld, putting the hidden through death and rebirth.

Wound & Shadow

Chiron marks the wound: the place that aches, and the place you can eventually heal others from. Black Moon Lilith marks the exiled self: the raw, untamed part that was told to behave.

Chiron · the woundGemini · 10th house

The wound is your voice and mind: a fear of being unheard or thought unintelligent, often set by being silenced or ridiculed young. You may talk fast to stay ahead of dismissal, or go quiet when the room feels unsafe. Healing comes from speaking anyway: trusting your ideas carry weight, and finding curiosity and play in how you say them. Lesson: intelligence does not need unanimous approval to be real. The wound is public: reputation, achievement, the fear of never doing enough in the world's eyes. Authority figures and career pressure may replay the original story. Healing comes through redefining success and becoming the mentor you needed.

Black Moon Lilith · the shadowAries · 9th house

She doesn't wait for the room to be ready for her. She walks in and lets the room adjust. Somewhere along the way she was probably called intense, intimidating, a lot; usually by people whose comfort she was no longer interested in protecting. Her work is not softening; it's aiming. Force without a target burns the people closest to her. Force with a target builds whole new worlds. Lilith expands through belief, travel and truth that was earned, not borrowed. Dogma and watered-down spirituality make you itchy. Your philosophy has to survive your own questioning.

Shadow Work

This chart runs on earth. Every element has a low expression and a high one: the work is knowing which way you are tilting, and the mantra that walks you back.

At your worst

Rigidity and quiet despair. Unchecked, the earth turns to stone: clinging to security, distrusting change, grinding through duty until the life has no joy left in it.

The middle ground

The everyday work is loosening the grip. Let some plans stay unfinished, let pleasure be productive too, and trust that safety can survive a little movement.

At your best

A foundation other people build on. At your best the earth is calm competence: you make things real, keep your word, and become the steady ground a whole circle relies on.

“I am already secure enough to let this change.”

Full Potential

Raw materials, not a verdict. Everything above was the chart describing itself. This is where it hands the pen to you.

This chart describes a capacity to build: to turn vision into something real, durable and genuinely useful in the world. You are wired to sustain: your gift compounds when you commit and refuse to abandon the thing halfway. With the Taurus Sun serving as both the chart's ruler and its core, the potential here is not a fixed fate; it is a set of raw materials. The chart names the tools. What gets built with them is the part astrology cannot tell you, and the part that is entirely yours.

Underneath everything, this is a chart learning to let a Taurus core be fed by a Taurus heart and carried out through a Leo face: three different instincts that only become one person when you stop making them compete.

the charge

Here is what the wheel cannot tell you. It hands you earth: patience, craft, and the will to build, and you are built to hold and sustain things. It gives you Sun as your compass and a map of where the pressure and the ease already live. But none of it is a verdict; it is equipment. The chart is the raw material; the life is what you make of it. That part was never written in the sky. It has always been yours to write.

Asteria · the geometryThe tightest aspects between your planets.

The closest conversations in the chart: where two planets sit at an exact angle and never stop talking. Tightest orb first; these are the loudest.

Neptune sextile Plutoorb 0.15°

In you, Neptune works easily with Pluto, bringing together your imagination, longing, and the dissolving impulse and your relationship to power and deep change. They support each other whenever you call on them, an inner talent available the moment you choose to use it.

Sun opposition Plutoorb 0.84°

In you, the Sun sits opposite Pluto, bringing together your core identity and will and your relationship to power and deep change. They hold opposite ends of one axis, each demanding its due, often felt as a swing between the two or projected onto the people around you. The work is holding both rather than choosing one.

Sun trine Neptuneorb 0.99°

In you, the Sun flows together with Neptune, bringing together your core identity and will and your imagination, longing, and the dissolving impulse. They cooperate so naturally you may not even notice the gift, an inner ease that grants talent, with the only risk being that you coast on it instead of developing it.

Mars opposition Saturnorb 0.99°

In you, Mars sits opposite Saturn, bringing together your drive and how you assert yourself and your discipline, fear, and sense of limits. They hold opposite ends of one axis, each demanding its due, often felt as a swing between the two or projected onto the people around you. The work is holding both rather than choosing one.

Mercury conjunction Venusorb 1.88°

In you, Mercury is fused with Venus, bringing together your mind and how you communicate and your capacity for love and pleasure. They act as one force, each unable to operate without the other, permanently blended and amplifying each other for better and for more intense.

Asteria · flow & frictionGifts & Challenges

Every chart runs on flow and friction. The gifts are where the energy already moves easily; the challenges are where it meets resistance: the places that ask for effort and pay it back as range and strength.

This chart runs on an even mix of flow and friction: real ease in some places, real effort in others, and range that comes from holding both.

Where it flows
Venus sextile Chironorb 0.1°

An easy, available link: Venus and Chiron feed each other with almost no effort. This is talent that shows up early and runs in the background.

Neptune sextile Plutoorb 0.1°

An easy, available link: Neptune and Pluto feed each other with almost no effort. This is talent that shows up early and runs in the background.

Pluto sextile Vertexorb 0.5°

An easy, available link: Pluto and Vertex feed each other with almost no effort. This is talent that shows up early and runs in the background.

Sun trine Neptuneorb 1.0°

A natural, flowing ease: Sun and Neptune feed each other with almost no effort. This is talent that shows up early and runs in the background.

Moon exalted in Tauruslifted

Moon is exalted: amplified and well-placed, giving back more than it costs you to use it.

Sun trine Vertexorb 1.4°

A natural, flowing ease: Sun and Vertex feed each other with almost no effort. This is talent that shows up early and runs in the background.

Where it works
Sun opposition Plutoorb 0.8°

A polarity asking to be balanced: the pull between Sun and Pluto never fully settles, and that restless charge is exactly what keeps you growing here.

Mars opposition Saturnorb 1.0°

A polarity asking to be balanced: the pull between Mars and Saturn never fully settles, and that restless charge is exactly what keeps you growing here.

Venus in detriment in Ariesuphill

Venus runs uphill in Aries, earning by effort what it does effortlessly elsewhere. That effort becomes real, tested range.

Mars in detriment in Taurusuphill

Mars runs uphill in Taurus, earning by effort what it does effortlessly elsewhere. That effort becomes real, tested range.

Venus square Vertexorb 2.2°

A productive friction: the pull between Venus and Vertex never fully settles, and that restless charge is exactly what keeps you growing here.

Venus square Neptuneorb 2.6°

A productive friction: the pull between Venus and Neptune never fully settles, and that restless charge is exactly what keeps you growing here.
