I'm a 1st year math PhD student and wish to transfer. I applied to transfer fall 2023 to 16 schools but didn't get in anywhere. I'm going to try again, but first I'll answer why I wish to transfer and how I ended up in my situation to give more context.
Why I wish to transfer: I want to be in a program with stronger students, a more challenging environment, and most importantly, professors in my research interests: algebraic geometry, number theory. My best option in pure math, given the professors who've left or retired over the 1st year, is discrete math (graph theory & combinatorics specifically). However, discrete math is still pretty far from algebraic geometry. In fact, there aren't even any courses in algebraic geometry being offered, so I study the material myself. As for the other issues, courses and qualifying exams posed no issue. It's suspicious how easy everything is going, even the research that I started this semester is flying by. With 2 professors I was scheduled to read through prerequisites and then attack a specific research problem. The semester and both research plans started early February, with credits for the spring and an expectation to continue during the summer. With 1 professor, I completed all the tasks mid March, and with the other I'm on track to finish by the end of April.
How I ended up in this situation: I wasn't able to get into a better school since I applied (in fall 2021) after only completing 2 years of undergrad and got my B.S. in 3 years (f19-s22). I thought about staying a 4th year, but my parents pressured against it citing the monetary cost. The undergrad math department offered no support (in fact, negative money, since by starting and finishing a masters in the 4th year, I would even lose the 4 year partial merit scholarship that I gained in 2019), while grad schools cover tuition and give you a stipend for living expenses. Given how many kids my dad has to support and my belief that a transfer is possible, I decided to start grad school.
What should I be doing to improve my chances? Next cycle is my last chance as if I don't get in for fall 2024, it's better to hustle and finish my PhD in 3 years. I have generally strong credentials that would normally make me a good applicant for a higher-ranked program.
I asked a professor, former chair of admission, and a few students to look over my CV and statement of purpsose when applying, so they're very polished. To not waste people's time, I also asked schools I got rejected from for feedback before posting to academia SE. One said
It's hard to say. We don't usually consider transfer students from graduate schools like yours - if a student is bringing a Master's degree, it is usually from a better school. You should be asking Directors of Graduate Admissions at more realistic schools. Your professors can give you advice. Kansas State and Carnegie Mellon might possibly play out for you.

We are less likely to accept PhD students from other programs. There has to be very good reasons for transfers. I should also say that at ---, we could only accept a small number of applicants this year and so it was more competitive than usual.
The biggest issue, mentioned even by programs that otherwise declined to give feedback, is there's 200-300 students applying for 7-12 spots. However, I consider myself qualified enough to contend for those spots. It appears that my reason for transferring wasn't good enough, and that the low prestige of my grad school (50-100th) hurts my chances. I knew that prestige might be an issue, but I didn't consider it to be such a large issue that I would get rejected from everywhere. Certainly I could've applied to schools just slightly better than my current one, but then all the problems which caused me to transfer except the subject area would remain. When applying, I mentioned the lack of professors in my subjects, but left out the part about student strength and difficulty after receiving mixed responses in feedback. One thing I might've failed to mention in my statement of purpose is just how strong my desire is to transfer, that I'm willing to give up 1 year just to be in my preferred field of research. Should I add that when reapplying? How else can I improve my application?
