I’m Leonidas AI, your decision-making engine.
Built by traders, for traders.
Signal in, noise out.
I read every curve, cargo and headline across the desk, and hand you back only what actually moves your book.
Rocket fuel for smarter traders.
Interpreting. Weighing. Synthesising. Three things you do in your head, done for you so conviction comes faster.
You can chase the call across four screens and a spreadsheet.
Or you can let me carry that load. I stitch curves, arbs, news, and seasonality together so you don’t have to. Pressure-test every strong idea, not just the two you had time to chase.
A terminal shows you what is. I show you what it means.
I tell you whether it’s signal or noise, early or late, a setup or a trap. I carry your book into every read, filtered for your coverage. I flag what comes next.
01 Watch
02 Synthesise
03 Weigh
04 Call
Nothing gets past me.
I watch your curves. Abnormal moves, flagged. Dated Brent moves outside its normal range, and I've already matched it against the news driving it.
Four signals, one answer.
A Brent-WTI arb looking wide is only real if the economics work: the freight, the grade differential, the timing. I walk the math before I call it open.
You move the levers.
I weigh arbs against news against fundamentals, so the read reflects how you actually trade. Move the levers, and the call updates.
The full call, built for you.
What changed. Why it matters. What to watch. What's the setup for the next move. The moment the picture changes, I deliver a new call, full picture behind it.
Never miss the window.
Set a threshold once: “alert me when WTI hits $82.” The second it triggers, you get the alert and the reason behind it.
A specialist's answer, every time.
Ask about ARA barge diffs and ICE GO cracks. You get a specialist call from a dedicated agent built for that vertical.
It's kind of like talking to another trader.

Think clearer, faster.
Q.
Is Dated Brent underpriced against the curve?
Get one answer. Backed by live prices, arb economics, news, seasonality, and your book.
Now the debate is about the trade.
We’re no longer debating which number’s right. We’re discussing the trade itself.
Distillates Trader
Everything on your desk.
Tell me what you trade.
Is the barrel clearing west or east, and which leg pays?
That’s the question a crude desk answers every morning. I answer it before you’ve finished your coffee.
On your screen from day one
WTI Midland FOB Houston, WTI/Brent, the Brent/Dubai EFS, and the export arbs west and east, with the VLCC and Aframax freight that gates each one.
What I do for you
I call the arb when it flips from shut to open. Break down the netback on both legs on demand. Brief you at start-of-day on what moved overnight and what it did to your book, Houston or Singapore, in your time zone.
Is Europe pulling US diesel, and is the arb still paying?
The transatlantic diesel arb is the whole game on a USGC distillate desk. I read it through HOGO so you know before the market does.
On your screen from day one
Heating Oil / ULSD, the USGC diesel differential, ICE Gasoil cracks, and the HOGO swap as your transatlantic read, with the USGC → Europe netback.
What I do for you
I flag when the arb flips shut to open and what’s driving it. I break down the HOGO conversion and the landed netback on demand. You get morning and settlement briefings on where the arb closed and the setup overnight.
West to NYH, or east to Pakistan? Your barrel has two exits.
An ARA gasoline book lives or dies on direction. I tell you which way the barrel wants to go, and when that changes.
On your screen from day one
EBOB, the RBOB/EBOB spread, Gasoline E/W, and Gas/Nap blend economics, the transatlantic pull west and the E/W legs draining east, side by side.
What I do for you
I alert you the moment the transatlantic or E/W arb opens or shuts. I run the landed netback into NYH on demand. I brief you on EBOB structure and what moved gasoline, every morning in CET.
Is the route tight, and does the rate still make the arb work?
That’s the question a freight desk answers before the first fixture drops. I answer it before you’ve had to check three screens.
On your screen from day one
TD3C VLCC AG–East, TD25 Aframax cross-Med, TC2 clean tanker transatlantic, and the key dirty and clean rates that gate your crude and product arbs, Worldscale and $/mt, side by side.
What I do for you
I flag when a rate move flips an arb from viable to unworkable. Break down the freight leg on any route on demand. Brief you at start-of-day on where rates closed, what fixed overnight, and what it means for the crude and product flows your book depends on.
Is high-sulphur tight enough to hold the crack, and is the East/West arb open?
A fuel oil desk trades the spread between the two grades and the pull between the two hubs. I keep both in front of you.
On your screen from day one
VLSFO and HSFO, the Hi-5 spread, the fuel oil crack, and the Rotterdam → Singapore East/West arb, read against bunker demand at the major hubs.
What I do for you
Alert you when the Hi-5 or the East/West arb moves through your level. Break down the blend and feedstock economics on demand. Brief you on where the crack and bunker premiums sit at start-of-day.

FAQs
What is Leonidas AI?
I’m the first decision-making engine for oil and commodity traders. I synthesise live data, prices, spreads, news, into actionable conviction. I trace why things are moving, weight the drivers, and show you my reasoning. I monitor your coverage in real time. When something abnormal happens, I flag it and match it to its driver. When the data moves, the conviction moves with it. I’m not making your decisions. I’m giving you the inputs, the reasoning, and the signals so you can decide. You shape your own view. I move with you.
What markets does Leonidas AI cover?
I cover crude, clean and dirty freight, gasoline, distillates (diesel and jet), and fuel oil.
Why does Leonidas AI beat a general model like ChatGPT or Claude?
A general model reads the internet, which is unvalidated, opinionated, and often wrong. It has no live prices, no arb economics, no memory of your book. It can talk about markets in broad strokes, but it can’t tell you whether a move is abnormal.
I run on Sparta’s own market data. Live prices, arb economics, news, seasonality, your book, all structured, validated, and real-time. I have years of depth in the commodities you actually trade: crude, distillates, fuel oil, freight. I wire it together into a live map of the market.
A general model is broad and shallow. I’m narrow and deep, built specifically for the markets you trade. That’s the difference between a chatbot that can discuss markets and a decision-making engine that actually trades them.
Does Leonidas AI learn from my data and share it with other customers?
No. I run on a tenant/landlord architecture. Your data and conversations stay isolated to your organisation. Sparta doesn’t train shared models on individual customer data or prompts.
What is Leonidas AI's reasoning actually built on?
A rulebook: a reasoning layer built on Sparta’s own trading logic. It runs as part of every answer, so what you get reflects how a desk actually thinks.
