This is a sub of our pillar on trading major sporting events, and the racing companion to our Cheltenham Festival guide. The National is to a casual punter the one race they bet all year, and to a trader it is the deepest, noisiest, most chaotic market in the calendar.

I have traded the National every year since the Exchange made it practical, and the lesson repeats: the enormous liquidity lets you trade real size, but the 40-runner field and once-a-year money make it a book to respect, not to outsmart. This guide covers the liquidity, the ante-post swing that suits it best, the unusually tradeable place market, and the in-running carnage — with a real worked trade and the non-runner discipline that protects you.

Why the Grand National is a unique trading market

The Grand National is the single biggest betting race in the world, and on the Betfair Exchange that translates into liquidity unlike any other racing market — tens of millions matched on the win market alone. But it is also the hardest race to read, because it is a 40-runner handicap over four and a quarter miles and thirty fences, where the favourite has a worse record than at almost any other championship event. The combination — enormous money, huge field, genuine chaos — makes it a market apart: deep enough to trade real size, unpredictable enough to punish anyone who treats it like a normal race.

The liquidity spike and where it goes

Grand National week brings money from people who bet on nothing else all year, and that flood does two things. It makes the win market spectacularly deep — you can back and lay four-figure sums without moving the price — and it makes the market behaviour unusual, because so much of the money is uninformed once-a-year betting rather than the sharp money that prices an ordinary race. The practical implication: prices can drift and steam on sentiment as much as form, which creates swings a disciplined trader can read, but also means the ‘value’ you think you see may just be the crowd. Trade the depth, but respect that this book is noisier than a Tuesday handicap.

Ante-post trading the National

The National rewards ante-post trading more than most races because the build-up is so long and so newsy. Weights are announced, the field firms up, the going changes, and big stables signal intentions — each of which moves prices in the weeks before. Backing a runner early and laying it back shorter after a positive trial or a confirmed entry is a classic swing trade across days. The risk specific to the National is acute: the 40-runner field means non-runners are common, and a horse you backed ante-post being withdrawn leaves you with a dead position. Know your non-runner exposure on every ante-post holding.

The place market: the National's quiet edge

Because the National pays out on more places than a normal race (typically the first four or five, depending on the bookmaker, with the Exchange place market reflecting the official terms), the place markets are unusually active and tradeable. A horse with strong stamina credentials can shorten dramatically in the place market as the race unfolds even if it never threatens to win. For traders who find the win market too chaotic, the place market offers a slightly more readable angle — staying ability matters more than finishing speed over the National distance, and that is a more stable thing to price than who jumps the last in front.

From the desk — an ante-post swing on the National

In-running: the wildest ride in racing

In-running the Grand National is the most volatile trading you can do on the Exchange. Prices fly as the field thins over the fences, a leader can go from 3.0 to 1.2 and back again as it makes and survives a mistake, and the long run-in produces dramatic late swings. The opportunity is obvious and so is the carnage: markets suspend on faller alerts and reopen against you, and the sheer field size means the picture changes faster than you can process. If you trade it in-running at all, do it with money you can afford to lose on that position, a pre-decided plan, and only after watching several Nationals without trading. This is the deep end of the deep end — most people lose at it.

A sane plan for National day

Decide your approach before the day, because the atmosphere is designed to make you bet, not trade. If you are an ante-post trader, aim to have your positions greened out before the off so you are flat into the chaos. If you are trading on the day, the pre-off win and place markets are deep enough to scalp or pre-race trade with size, using a hard stop. Ring-fence a specific National bankroll and keep your normal staking discipline — the once-a-year occasion tempts once-a-year stakes. Size every green with the calculator. And whatever you do, separate the National from the other big set-pieces in your planning: it is its own beast, more chaotic than the World Cup and less readable than a Premier League match, and it deserves its own clear-headed plan.

The fences effect on in-running prices

What makes the National's in-running market uniquely wild is the fences. Becher's Brook, the Chair, the Canal Turn — each is a point where the field can be reshaped in seconds by fallers and mistakes, and the Exchange reacts violently to every one. A horse travelling well can be repriced from 8.0 to 3.0 after surviving a scare at a key fence, then drift again on the long run to the next. The market also suspends repeatedly as faller alerts come through, and reopens with prices that have leapt while you could not trade. For an in-running trader this means two things: your stop may not fill at the price you want because the market gapped through it during a suspension, and the picture you are trading is always a few seconds behind reality. It is the clearest example on the Exchange of why in-running is high-variance — the very structure of the race fights your ability to manage a position.

Trading the build-up, day by day

The National's ante-post value is spread across the build-up, and it pays to know the rhythm. Weights day (when the handicap is published) is the first big mover, as the market reassesses every horse against its allotted weight. The five-day and final declarations firm the field and trigger non-runner adjustments. The 24 hours before bring going updates and stable confidence, which move prices sharply. A swing trader works this calendar deliberately — taking early positions on weights day when prices are widest, and trading out into the steam as confirmations arrive — rather than waiting for race morning when much of the value has gone. The companion festivals work the same way; the Cheltenham guide describes the same build-up-then-event shape, and the major events pillar generalises it across every big occasion.

Splitting your bankroll: win, place and in-running

A sane National plan divides your bankroll by risk. The largest, calmest portion goes to ante-post and pre-off win/place trading, where the deep books and the build-up give you readable, manageable positions. A smaller, ring-fenced portion — money you have genuinely written off — is the only money that should ever touch in-running, because that is the part you can lose in a single suspended market. The place market deserves its own allocation because it behaves differently from the win market and can be traded when the win market is too chaotic. Keeping these separate stops a bad in-running moment from eating the green you built ante-post, and it enforces the discipline our bankroll management guide insists on: never let your wildest position have access to your whole float.

Why ‘value’ is a trap in the National

More than any other race, the National tempts traders to believe they have found value, and more than any other race they are usually wrong. The 40-runner field, the marathon trip, the fences, and the flood of sentiment money mean the result is genuinely closer to a lottery than a Tuesday handicap — the favourite's poor historical record is the proof. The trading lesson is to lower your conviction: trade the price movements the build-up and the crowd create, rather than betting on your read of who will actually win, because your read is less reliable here than anywhere. The traders who do well at the National are humble about the result and disciplined about the trade; the ones who blow up are certain they have spotted the winner the crowd has missed.

The liquidity timeline on National day

The money does not arrive evenly on National day, and knowing the timeline tells you when to trade. From the morning, the win and place markets carry the heavy ante-post money and react to going updates and final declarations in considered moves — the window for knowledge-led swing positions. Through the early afternoon, as the supporting card runs, money steadily concentrates on the big race. The real depth — the once-a-year flood — arrives in the final thirty to forty minutes before the off, which is when pre-race trading and scalping have the deepest book and the most frequent oscillations to work with. Then comes the off and the in-running chaos. Map your day to this curve: research and ante-post management early, your sharpest pre-off trading in that final window, and a clear-eyed decision about whether to touch in-running at all. Trading against the curve — forcing scalps before the book has filled, or chasing ante-post moves in the frantic last minutes — is how traders give back what the deep market gave them.

A National-day checklist

• Account funded and verified well in advance — do not rush sign-up on the day under time pressure.
• Ante-post positions identified with a plan to green them out before the off.
• Non-runner exposure checked on every holding — the 40-runner field makes withdrawals common.
• In-running money ring-fenced and written off — only money you can lose on a single suspended market.
• Stops set and the calculator open so every green is even and every position has a pre-decided exit.
• Normal staking discipline from the bankroll guide — the occasion tempts once-a-year stakes; resist it.

FAQ

Why is the Grand National hard to trade? It is a 40-runner handicap over four and a quarter miles and thirty fences, so the result is far less predictable than a normal race — the favourite has a poor record. The market is also flooded with once-a-year money that prices on sentiment as much as form, making prices noisier. The depth lets you trade size, but the chaos punishes anyone treating it like an ordinary race.

Can you trade the Grand National ante-post? Yes, and it suits the race well because the long, newsy build-up — weights, entries, going, stable signals — moves prices for weeks. Backing early and laying back shorter after positive news is a classic swing trade. The key risk is non-runners: with 40 entries, withdrawals are common, so green your position out before the race rather than carrying a holding that could become a dead bet.

Is the Grand National place market worth trading? Often, yes. Because the National pays out on more places than a normal race, the place market is unusually active and can be more readable than the chaotic win market — stamina, which matters most over the distance, is more stable to price than finishing speed. Traders who find the win market too wild sometimes prefer the place angle.

Should beginners trade the Grand National in-running? No. In-running the National is the most volatile trading on the Exchange — prices fly as the field thins, markets suspend on faller alerts and reopen against you, and the picture changes faster than you can process. Watch several Nationals without trading first, and only ever trade in-running with money you can afford to lose on that position.
