State Street’s SPYM fund has surpassed $100 billion in assets, reaching this milestone in just 283 trading days. The ETF offers low fees of just two basis points, catering to retail markets. However, experts predict a slowdown in new core S&P 500 funds due to existing large funds tracking the index.

SPYM, previously known as SPLG, joins the primary S&P 500 ETF offerings, targeting the retail segment. Other offerings like IVV, VOO, and SPY cater to different market segments. In Q3 2025, VOO saw $6.6 billion in net inflows, IVV added $3.6 billion, while SPY experienced outflows of $1.7 billion.

The ETF industry is categorized into passively managed, low-cost beta funds, mid-priced actively managed funds, and high-priced funds with complex products. Newer entrants focus on active management and derivatives, but Vanguard, State Street, and BlackRock dominate the low-cost segment, expected to remain unchallenged.
