Taylor Swift and Kansas City Chiefs tight end Travis Kelce said on 26 August that they are engaged, posting photos of Kelce proposing in the garden of his Missouri home. The announcement caps a high-profile two-year relationship that has spanned Swift’s record-breaking Eras Tour and Kelce’s third Super Bowl title. Jewelry investors moved quickly. Shares of Signet Jewelers, the parent of Kay and Zales, jumped intraday on the engagement news and were still active the following morning; trading volumes at 10:20 a.m. New York time on 27 August were about eight times the stock’s one-month average. Market watchers tied the surge to images of Swift’s cushion-cut diamond ring, a style Signet brands sell heavily. Specialists contacted by Forbes put the ring’s value near US$650,000, underscoring the couple’s spending power. Swift’s fortune stands at roughly US$1.6 billion, thanks largely to touring and the recent purchase of her master recordings, while Kelce’s wealth is estimated at about US$70 million, producing a combined net worth close to US$1.67 billion. The cultural ripple spread beyond equities. Online prediction markets such as Kalshi and Polymarket logged about US$80,000 in fresh bets on the timing of the wedding and potential future milestones within hours of the post. President Donald Trump and a host of sports and entertainment figures also offered public congratulations, highlighting how the engagement has fused pop culture, sport and finance.
