In September 2025, TSP stock funds remained positive despite the looming government shutdown. The C Fund gained 3.65%, the S Fund rose 2.04% , and the I Fund jumped 3.16% (25.34% YTD), driven by a steady market with the S&P 500 up 0.4% and the Dow up 0.2% to close out the month. The G Fund lagged at 0.35%.
As of June 2025, there are 171,023 TSP millionaires, and that number is likely to rise when third-quarter figures are released. While the average TSP millionaire has 28 years of federal service, some participants may have recently left government amid ongoing uncertainty and workforce changes. Even so, the TSP continues to shine as a source of financial stability for federal employees, offering a rare bright spot in a year marked by shutdown fears and potential job cuts.
