Vietnamese Tennis: The Audience Exists, the Rights Price Does Not

Last March, in a sponsorship renewal meeting in Binh Duong, a representative of a beverage brand asked me exactly one question: "Show me the real audience for this tennis event." On the table lay fourteen pages of documents — court diagrams, a list of sixty-four players, ticket allocations, a three-month communications plan, a referee and ball budget. Not one page carried audience data. The organisers knew precisely that 3,180 tickets had been issued, that seven sponsors had signed on, and what each operating line item cost. They did not know how many people watched the semi-final on the livestream, for how long, or from which province. The meeting ran seventy minutes and ended in a deferral. That was the fourth time in eighteen months I had sat in such a room.

To understand why that gap matters more than it appears, Vietnamese tennis has to be placed at the right layer of the global power chain. The four Grand Slams sell their own rights. The ATP and the WTA sell tour rights in packages. The ITF holds the Davis Cup, the Billie Jean King Cup and the World Tennis Tour. Money flows back upstream, concentrating where the highest-quality broadcast hours are. Small markets like Vietnam rarely buy individual properties; they buy bundles, or they receive tennis as a throw-in inside a larger contract.

Domestically, the hierarchy is clear: football takes the bulk of sports spending and tennis sits on the second tier. But the audience structure of that second tier is unusual. Vietnamese tennis viewers cluster in cities, aged 30 to 55, with above-average incomes, many of them business owners or mid-level managers. They play at weekends, buy racquets, hire coaches and enrol their children. This group is small in number but dense in commercial value, which is why banks, insurers, car brands and healthcare companies keep signing.

On the player side, Vietnam has Ly Hoang Nam — the 2026 Wimbledon boys' doubles champion alongside Sumit Nagal, a milestone recorded in ITF records and still the highest international achievement in Vietnamese men's tennis. On the women's side, Nguyen Thuy Linh has held the domestic number one position for years and carries most regional expectation. The national team still competes in Davis Cup Asia-Oceania Group III. That base is enough to sustain a presence, not enough to create a rights market.

Most of the revenue from an international tennis event staged in Vietnam does not come from spectators. For a Challenger 50 event, the ATP-mandated prize purse sits at roughly forty thousand US dollars; Challenger 100 and 125 tiers are higher, around one hundred and thirty thousand and one hundred and sixty thousand US dollars respectively. The real operating budget typically runs two to three times the prize purse: courts, balls, officials, medical cover, security, communications, player travel. Issue three thousand tickets at an average of two hundred and fifty thousand dong and total gate revenue lands near seven hundred and fifty million dong, equivalent to under thirty thousand US dollars. That does not cover the prize purse, let alone operations.

The entire shortfall is filled by local sponsorship and host-city support. Organisers therefore optimise for what they must prove: logo counts on banners, press mentions, trophy-ceremony photographs, sponsor interview clips. Nobody pays for audience measurement, so nobody measures.

The cost of an international tennis event in Vietnam is covered by local sponsors, not by spectators — so organisers optimise for imagery, not for audience data.

That explains an easily observed paradox: the same tournament can announce "millions of impressions" in a press release while being unable to hand a client a single credible livestream traffic report.

At the other end of the system, the money sits with the Grand Slams. The 2026 Wimbledon prize fund stood at roughly fifty million pounds; the same year's US Open at roughly seventy-five million US dollars, according to the two tournaments' own announcements. A Vietnamese player reaching a Grand Slam main draw generates media value far beyond winning a domestic title. A Grand Slam qualifying berth is therefore worth far more economically than a domestic ranking position, even though both are filed as achievements.

For Ly Hoang Nam, the most durable commercial asset is not accumulated prize money on the ITF and Challenger circuits. It is the 2026 junior Wimbledon title — an asset created in two weeks and still pricing endorsement deals a decade later. Vietnamese professionals at tour level earn modestly from competition; most real income comes from image rights, academies and corporate coaching programmes. Coaching a bank executive delivers steadier cash flow than winning a Challenger first round.

Then there is the part of the market nobody measures: the grassroots game. Hourly court rental, club membership fees, junior class tuition, racquet and shoe sales, corporate tournaments running year-round. I do not have a reliable national data source to assert its size, and that is a genuine limit of this analysis. But an open calculation shows the order of magnitude: assume around one thousand five hundred active courts nationwide, four hours of rental per court per day, two hundred thousand dong per hour, operating three hundred and fifty days a year. The assumed result lands near four hundred and twenty billion dong annually in court rental alone, several times the total media rights value the Vietnamese tennis market could generate today. Whoever controls access to the customers paying that money controls pricing — not whoever holds the broadcast rights.

There is one technical variable usually ignored in valuation: viewing behaviour. Grand Slam finals air in the early hours of Vietnamese morning. Based on my experience watching matches at southern venues and across various streaming platforms, domestic viewers break their attention into short sessions, watch on phones, through unofficial links, and catch replays the next morning. Any measurement counting only official broadcast misses a large share of the real audience. I once built a sponsorship-efficiency model on sixty-four matches of data and forecast nearly three times the actual result, purely because I ignored late-night viewing habits. A failed forecast is not a failure; it is free data for the next calculation. Since then, every media valuation I build carries a separate viewing-behaviour line, distinct from the gross impressions line.

The industry's default explanation is that Vietnamese tennis lacks stars, so the rights hold no value. The star shortage is real, but it is the secondary cause. The binding constraint sits at the measurement layer. Rights prices are not set by popularity; they are set by the ability to prove and repeat a specific audience, in a specific time slot, in front of a specific group of advertisers.

Rights are not priced by popularity, but by the ability to prove and repeat an audience.

The consequence is two entirely different kinds of investment. Hosting an international event delivers short-term glow: a week of coverage, an opening ceremony, a handful of photographs. Building a domestic club competition system — with a ranking, a stable calendar, player and audience data — delivers long-term value with little glow. Vietnamese tennis leans heavily toward the first. New media does not kill brands; it exposes brands that have no substance. A tournament that cannot measure its own audience is an unverified brand, however many banners it hangs.

Over the next eighteen to twenty-four months, the first Vietnamese organisation to build a verified tennis audience panel — by cohort, by time slot, by device — will set the price for the rest of the market. If a regional OTT platform folds tennis into a football bundle first, the door closes and the price gets set from outside. This judgement assumes no change in sports rights regulation; a Vietnamese player reaching the second week of a Grand Slam would compress that window to months. The final question is not how many people watch Vietnamese tennis, but who holds the right to define "viewer".
