The Money Behind the Baseline: Two Balance Sheets of Professional Tennis

On 8 June 2026, Carlos Alcaraz lifted the Roland Garros trophy on Court Philippe-Chatrier and collected 2.55 million euros in prize money. At the same moment, more than ten thousand kilometres from Paris, on an outdoor court in Da Nang, a Vietnamese player ranked outside the world's top 900 won his first round at a 15,000 USD ITF World Tennis Tour event and received exactly 258 USD. He paid for his own hotel, food, stringing and the flight from Binh Duong. After everything was deducted, that victory left him several hundred thousand dong in the red. I sat in the third row watching the electronic scoreboard change numbers and asked myself: is this one sport, or two sports sharing a single name?

People call it the tournament structure; I call it the first balance sheet of a two-price system.

Professional tennis is organised as a tight pyramid. At the top sit the four Grand Slams, the Australian Open, Roland Garros, Wimbledon and the US Open, each paying tens of millions of dollars in prize money, drawing hundreds of millions of viewers and signing broadcast deals worth hundreds of millions. Directly below sit the ATP and WTA Tours, with Masters 1000, ATP 500 and ATP 250 events. Lower still is the ATP Challenger Tour, where total prize money per event runs from only 40,000 to 220,000 USD. At the bottom lies the ITF World Tennis Tour, made up of 15K and 25K events, where most young players and those genuinely clinging to the tour make their living.

When I first began following tennis seriously, I thought I was watching a sport. After a few seasons, I realised I was reading a financial report that happened to include serves and returns.

There is a number the stands almost never notice. At an ITF 15K event, the 15,000 USD total purse is divided among about thirty-two players. The champion takes roughly 2,160 USD; a first-round loser takes a few hundred. But the cost for a Vietnamese player to attend an international event, including flights, hotel, food, stringing, and hiring a coach or hitting partner, runs from 1,500 to 3,000 USD per week. In other words: win the whole event, and the prize money still does not cover the cost. To genuinely break even, a player would have to win three or four ITF events in a row, something close to impossible.

At the lowest tier of tennis, prize money is not income; it is a partial reimbursement of expenses, and the real income sits on an entirely different sheet. That other sheet holds kit sponsorship, racquet-manufacturer contracts, support from local federations, and, in some cases, money flows that appear in no transparent ledger at all.

Roland Garros 2026 announced a total purse of around 56.5 million euros. The 2026 US Open paid a record total of 75 million USD, with the men's singles champion taking 3.6 million USD. Looking at that table, fans imagine tennis is a wealthy sport. But if you are the world number 700, you do not live in that table. You live in the ITF table.

Based on my experience following matches, I once tracked a Vietnamese player who came up through an academy in Binh Duong. He beat many opponents on the South East Asian junior circuit, but when he stepped onto the professional tour he could not find regular sponsorship. No sponsorship means no private coach, no fitness specialist, no video analysis, no quality hitting partner. He played well enough to reach main draws, but was not rich enough to last into a third month. I record every footprint on the court so that when they wipe their hands clean, I can recognise each hand.

This is the mechanism I call the two balance sheets. The first is the public sheet: prize money, ranking points, seedings. The second is the hidden sheet: travel costs, academy fees, personal sponsorship deals, appearance fees at exhibition events, and arrangements that are never disclosed. A player can rise on the first sheet while quietly sinking on the second, and vice versa. Fans only ever see the first sheet.

Take a more concrete example. A young player who reaches the semi-finals of a 100,000 USD Challenger might take around 6,000 USD in prize money. That number does not sound bad. But if he has to fly from Vietnam to Europe, bring a coach, rent practice courts, and pay for recovery and physiotherapy, most of that money evaporates within two weeks. That player is working full time at a job that does not pay enough for him to keep doing the job.

This is not a Vietnamese story alone. In any country without a solid sports-finance foundation, young players fall into the same trap: they need money to play, but they only have money if they win, and they only win if they already have money to play. It is a closed loop that no amount of raw talent can break.

A view repeats endlessly on forums: if you are not making money, you are simply not good enough. That is half the truth, and the other half lies in how the system is designed. ITF-tier players do not compete on technique alone; they compete on resources. An eighteen-year-old European player has a national federation paying his costs, a private coach, and free practice courts. A Vietnamese player of the same standard must fund everything himself, and is pushed back from the starting line by the prize-money system. That gap is not measured in technique. It is measured in account balance.

From the view of someone who follows the money, I see a familiar power structure here: the people who decide how money is distributed never compete, and the people who compete never decide the money. The four Grand Slams and the tour governing bodies decide how much is shared, with whom, and by what formula. No mechanism forces them to spend more on the base. When you ask why the first-round share at a Grand Slam has fallen in relative terms against the total purse, the answer is always that it honours the champion. No one states the rest: the base is where the money is compressed so the top can swell.

But I do not believe in a single conspiracy behind all of it. I believe in the gap between the two balance sheets, and in the fact that no one is accountable for narrowing it. That is how power works: no one has to give an order, as long as a formula is left untouched long enough to become custom. Tennis has left that formula untouched for decades.

When bookmakers know in advance and umpires know it too, the match is just a script for the stands, and at ITF level, where a player can be paid more than an entire event's prize money simply to lose a set, that script gets cheaper. I am not saying every ITF match is fixed. I am saying that when official prize money cannot sustain a player, the underground market will pay the difference, and it always finds the person who needs the money most. This is what international tennis integrity reports have warned about repeatedly: most betting-related violations come from events with low total purses.

So where is the reasonable part of the let-the-market-decide view? It lies here: base-tier prize money cannot rise indefinitely, because revenue comes from viewers and sponsors, and they pay for stars, not for the world number 800. That is an uncomfortable truth. But from that truth there are two roads. The first: accept that the base is a sacrifice zone, and that every consequence, from fixing to quitting to wasted talent, is the price to be paid. The second: treat the base as the sport's infrastructure, and invest in it the way you invest in stadiums, because without a strong base, the top has no successors.

I do not believe in hunches; I believe in the half-cent discrepancy on a transfer ledger, and in this case that discrepancy has a name: it lies between 258 USD and 2.55 million euros.

When the big season returns, the stands fill again, and television shows the stars' 220 km/h serves. Somewhere outside the frame, a Vietnamese player is still checking his hotel bill after the first round. The question is not whether this sport still exists. The question is: who will pay for the base to keep existing, when those who benefit most from it are the ones who have never stood there?
