LA28 Olympics to Transform SoFi Stadium into Largest-Ever Aquatic Venue

When the Olympic Games return to Los Angeles in 2028, organizers will rely on a radical blueprint: building zero new permanent venues. Instead of constructing billion-dollar facilities that risk becoming abandoned "white elephants," LA28 is leveraging the region's existing sports infrastructure. The crown jewel of this sustainability strategy is SoFi Stadium in Inglewood, California. Normally home to the NFL's Los Angeles Rams and Chargers, the $5.5 billion technological marvel will undergo an unprecedented transformation. For nine days in July 2028, the 101,000-square-foot football field will be converted into a world-class natatorium, becoming the largest swimming venue in the history of the Olympic Games.

The scale of the planned aquatic center shatters all previous benchmarks for the sport. By utilizing the massive footprint of SoFi Stadium, organizers anticipate accommodating up to 38,000 spectators for swimming finals. This nearly doubles the current world record for swimming attendance—22,209 fans—which was recently set during the 2024 U.S. Olympic Trials at Lucas Oil Stadium in Indianapolis. The Los Angeles City Council officially approved the venue change, moving the swimming events outside the city limits to Inglewood to capitalize on the stadium's massive capacity and state-of-the-art amenities, including its pioneering 80-million-pixel Infinity Screen suspended above the field.[1][2]

The confidence to execute this massive undertaking stems directly from a recent, highly successful proof of concept. Originally, LA28 organizers planned to host swimming in a temporary structure built over Dedeaux Field, the baseball stadium at the University of Southern California, which would have seated roughly 17,000 fans. However, those plans were scrapped after officials witnessed the 2024 U.S. Olympic Swimming Trials. Held inside Lucas Oil Stadium—the indoor home of the NFL's Indianapolis Colts—the event proved that modular pools could be seamlessly integrated into massive professional sports arenas without compromising the competitive environment. The overwhelming success and record-breaking ticket sales in Indianapolis convinced Los Angeles officials to double down and move the event to the even larger SoFi Stadium.[1][2]

Transforming a professional football field into an Olympic-caliber pool requires a feat of rapid, high-precision engineering. The mechanism relies on modular stainless-steel pool systems. Rather than digging into the stadium floor, engineers construct a raised platform across the entire expanse of the turf. Above this sub-floor, prefabricated stainless-steel panels are bolted together to form the pool walls, which are then sealed with a custom PVC liner and filled with over a million gallons of water. This temporary infrastructure must meet exact Olympic tolerances, featuring advanced gutter systems tuned for wave suppression to ensure a "fast" pool for the athletes.

What remains largely invisible to the spectators is the rigorous environmental and hydrodynamic calibration required to make a temporary stadium pool viable for world records. In a standard indoor natatorium, climate control is highly regulated to manage humidity and air quality. SoFi Stadium, while covered by a massive translucent canopy, is technically an open-air venue with open sides that allow ocean breezes to flow through. Engineers must carefully manage water temperature and air currents to ensure equitable conditions across all lanes. Furthermore, the depth of the temporary pool and the precision of its water-return systems are critical; a pool that is too shallow or lacks proper wave-absorbing gutters will cause turbulence, slowing the swimmers down.

The logistics of the SoFi Stadium conversion have fundamentally altered the traditional Olympic schedule. Historically, swimming dominates the first week of the Games, while track and field takes over the second week. For LA28, this order is reversed. SoFi Stadium is slated to co-host the Olympic Opening Ceremony alongside the historic Los Angeles Memorial Coliseum in an unprecedented dual-venue format. To accommodate the ceremony, organizers will build a temporary, removable stage over the partially constructed swimming pool installation. Once the opening festivities conclude, crews will work around the clock to remove the stage and finalize the aquatic setup.[3]

Because of this rapid turnaround, swimming events will take place from July 22 to July 30, 2028, occupying the final week of the Games. The preliminary heats will run for the first eight days, culminating in a massive "Super Saturday" that will feature five swimming finals alongside dozens of other medal events across the city. The final medals of the entire Olympic Games will be awarded in the medley relays on Sunday afternoon, just hours before the Closing Ceremony takes place back at the Coliseum.[3]

The shift to a stadium-scale venue also reflects a broader evolution in aquatic sports presentation. World Aquatics, the international governing body for water sports, has embraced the move, noting that the massive capacity will elevate the sport's global profile. The LA28 Games will also feature an expanded swimming program, with the International Olympic Committee recently approving the addition of six new sprint events: the men's and women's 50-meter backstroke, breaststroke, and butterfly. This brings the total number of swimming medal events to 41, ensuring that the record-breaking crowds at SoFi Stadium will witness more podium moments than at any previous Olympics.

While the modular pool strategy solves the Olympic "white elephant" problem, it introduces unique scheduling constraints, particularly for the Paralympic Games that follow. Because the temporary pools must be completely dismantled and removed from SoFi Stadium in time for the NFL preseason in August, Paralympic swimming cannot be hosted in the same venue. Instead, Paralympic aquatic events will be held at a temporary pool facility in Long Beach, which will also host Olympic water polo. This logistical reality has sparked some debate among advocates who prefer Olympic and Paralympic athletes to share identical venues, though organizers maintain that the NFL calendar makes a prolonged stadium takeover impossible.

The SoFi Stadium project is part of a wider decentralization of aquatic sports for LA28. By separating the disciplines, organizers can match each sport with a facility perfectly suited to its specific competitive demands. While swimming takes over the massive NFL stadium, diving will be hosted at the celebrated Rose Bowl Aquatics Center in Pasadena. Meanwhile, artistic swimming, open water swimming, and water polo will be clustered in Long Beach, creating an intimate, festival-like "neighborhood" atmosphere for fans attending multiple events in a single day.

The financial implications of this venue shift are substantial for the privately funded LA28 organizing committee. By expanding the seating capacity from the originally planned 17,000 at USC to nearly 40,000 at SoFi Stadium, organizers stand to generate millions of dollars in additional ticket revenue. Swimming is consistently one of the most-watched and highest-grossing Olympic sports, and maximizing live attendance is a core pillar of LA28's strategy to turn a profit. Los Angeles Mayor Karen Bass emphasized that optimizing venue capacities across the region is essential to ensuring the Games leave a positive financial legacy for the city, mirroring the profitable outcomes of the 1932 and 1984 Los Angeles Olympics.[1]

Ultimately, the LA28 model aims to rewrite the economic playbook for mega-events. By relying on temporary, modular infrastructure inside existing world-class arenas, the host city avoids the billions of dollars in long-term debt typically associated with Olympic construction. Furthermore, the modular pools used at SoFi Stadium will not go to waste. As has become a tradition with temporary Olympic and Olympic Trials pools, the stainless-steel structures will likely be dismantled after the Games, sold, and permanently reassembled at community aquatic centers, leaving a tangible, usable legacy long after the stadium returns to football.[2]
