$EUV vs $LAZR

The short version

EUV is cheaper to own, at 0.35% a year versus 0.75%. LAZR is the bigger fund, with $81M in assets. EUV has been around longer, launching on May 6, 2026.

EUV

The Corgi Lithography & Semiconductor Photonics ETF takes a wider angle on photonics, centered on lithography and chipmaking: the light-based tools that print chips, the equipment makers around them and the foundries that use them. Large positions have included ASML, TSMC, Applied Materials, Lam Research and KLA. Because it leans on large semiconductor equipment and foundry names, EUV behaves more like a chip-equipment fund than a pure optical networking fund. That can make it steadier than the pure plays, but it is a different bet.

LAZR

The Tema Photonics & Optical ETF invests in global photonics and optical technology companies tied to AI data movement, including optical interconnect, semiconductor technology and related equipment and materials. Tema launched it with research input from semiconductor analysis firm SemiAnalysis. LAZR has also held a position in privately held AI company Anthropic, which is unusual for an ETF. Private positions are valued differently from listed stocks and can be harder to trade, so read the prospectus on how they are handled.

Lower fees and more assets are helpful, but they are not the whole story. The bigger question is which strategy matches what you want to own. This comparison is not a recommendation to buy or sell either fund.
