Major League Baseball is moving toward its first expansion since the Tampa Bay Devil Rays and Arizona Diamondbacks paid $130M each in 1998, with commissioner Rob Manfred targeting a 32-team league after the Oakland Athletics complete their Las Vegas relocation in 2028. Sacramento, Nashville, Charlotte, Portland, and Salt Lake City have all filed formal expressions of interest, with entry fees projected between $2.2B and $2.5B per franchise.
Sacramento's bid carries unusual momentum. The city is temporarily hosting the Athletics for three seasons at Sutter Health Park, a 14,000-seat minor-league facility, while the team's Las Vegas stadium completes construction. Local ownership groups, including tech executives from the region's agribusiness software corridor and real estate operators behind the Kings arena district, are assembling a pitch centered on Northern California's 2.4M metro population and the fourth-highest median household income among Western markets without MLB. The Sacramento River Cats, the city's Triple-A affiliate, averaged 8,200 fans per game last season, second in the Pacific Coast League. One sponsor executive familiar with the effort said the Sacramento group is modeling its presentation on the NHL's Seattle Kraken expansion playbook: corporate suite presales, a downtown stadium site with adjacent mixed-use development, and a media strategy that treats the Bay Area as competitive leverage rather than obstacle.
Nashville and Charlotte represent the Southeast counter-narrative. Nashville's 2.1M metro has added 440,000 residents since 2010, and the city's Music City Baseball group, led by Titans minority owner John Loar and private equity operator Stewart Granger, already controls a 15-acre North Nashville stadium site. Charlotte, with 2.8M metro residents and the Carolina Panthers owner David Tepper circling the baseball opportunity, would give MLB a second team in the Carolinas and a direct pipeline to the Research Triangle's corporate sponsor base. Both cities are pitching the league on demographics: younger, faster-growing, and more aligned with MLB's strategy to recapture fans under 35 who have drifted toward NBA and international soccer. Nashville's group has quietly met with Rawlings, Louisville Slugger, and Fanatics about local manufacturing and distribution deals that would underwrite part of the stadium financing.
Portland and Salt Lake City complicate the Western math. Portland's 2.5M metro and no-state-income-tax advantage appeal to player agents, but the city lacks a committed stadium plan after the Beaverton site collapsed in 2023. Salt Lake's bid, backed by Qualtrics co-founder Ryan Smith, who also owns the Jazz, would pair baseball with the 2034 Winter Olympics infrastructure and leverage the state's $92M annual tourism marketing budget. Smith's pitch includes a retractable-roof stadium in the Power District, directly adjacent to his planned Jazz arena renovation. The question for MLB is whether the West can support four new teams—Las Vegas, Sacramento, Portland, Salt Lake—or whether the league prioritizes geographic balance and sends two East, two West.
Expansion timing depends on three gates. First, the Athletics must finalize their Las Vegas stadium financing and break ground, expected by late 2025. Second, MLB's Collective Bargaining Agreement expires after the 2026 season, and players will demand a cut of expansion fees, likely routed into competitive balance or revenue-sharing pools. Third, the league must resolve its stadium crises in Tampa Bay and Oakland's former territory, where the Rays are negotiating a $1.3B replacement and the A's departure leaves a litigation trail involving the Coliseum site and Howard Terminal rights. Manfred has told ownership groups to prepare for a formal expansion application window opening in 2028, with play beginning in 2031 or 2032.
Watch for Sacramento's corporate sponsorship announcements in the next six months—if they land a founding partner at $15M-$20M annually, the bid moves from aspirational to operational. Nashville's stadium financing package is due to the Metro Council by December 2025. Charlotte's timeline hinges on Tepper, who has not yet committed capital but has quietly assigned two front-office executives to model baseball economics. Portland's window is closing; without a site by mid-2026, the city falls behind. Salt Lake's advantage is Smith, who can write a $500M equity check and whose Olympic deadline creates political urgency the other cities lack.
MLB's last expansion added $260M to league coffers. This round, at $2.2B per team, delivers $4.4B split among 30 existing franchises—$147M each, before player concessions. The cities bidding are not paying for nostalgia. They are paying for the last available inventory in North American major-league sports, and they know it.
