Not so!
Your profile says you are in The States which still has a few cons to choose from depending where you live.
Seems most events have already happened this year and sadly 2025 was the last year for BABS Con in Burlingame, CA. A few upcoming cons in the US I am aware of that might be of interest are:
https://ponyvilleciderfest.com/ Milwaukee, WI (Less than 40 days away)
https://hearthswarmingclub.com/ Ithaca, NY. (Less than 2 months away)
https://trotcon.net/ Columbus, OH. 2026.
https://everfreenw.com/ Bellevue, WA. 2026
https://harmonycon.org/ Dallas, Texas. 2026
https://www.seaquestriafest.com/ TBA 2026
There is also a more how should I say.. Risqué convention called Mare Fair who's attendants ended up collectively donating over $100,000 USD during their charity auction last month. commendable for a fandom that isn't really a thing anymore I was at Galacon 2025 in Germany the same weekend where a more modest €34,500 Euros was raised for Make A Wish.
There is still an enormous amount of people interested in MLP even if they aren't so easy to spot in public.
Yes MLP isn't in the public eye or the craze that it was and sadly the big conventions like BronyCon may have said their farewells but in their place stands dozens of smaller ongoing annual conventions and meetups. MLP inspired art, music and animations are being made to this day in unbelievable amounts and quality.
Things are a little quieter now, sure, but MLP fans wont be going anywhere for a gooooooood long time.
Oh, and a warm welcome to MLP Forums!
