\begin{frame}[fragile]
	\frametitle{Title}
	
	\vspace{-0.1cm}  % Reduce space after title
	We are interested in how similar two sets are. 
	\vspace{0.4cm}   % Increase space before tikzpicture
	
	\centering
	\begin{tikzpicture}
		% Add a box around everything with some padding
		\draw[black, thin] (-2.5,-2.5) rectangle (4.5,2.8);
		
	
	\end{tikzpicture}
	
	\only<4->{
		The standard measure is the so-called Jaccard similarity.
	}
	

	
	\only<4>{\[
		0 \leq \frac{A \cap B}{A \cup B} \leq 1 
		\]
	}
	
	
	\only<5>{\[

	}

\end{frame}

I tried using \visible  instead of \only but this then doesn't show the transitions.  I also tried \vphantom but I couldn't get it to work. How can I keep the box and the text above it steady?

I'd use a top-aligned frame:


```
\documentclass{beamer}
\usepackage{tikz}
\begin{document}

\begin{frame}[t,fragile]
	\frametitle{Title}
	
	We are interested in how similar two sets are. 
  
  \medskip

	\centering
	\begin{tikzpicture}
		% Add a box around everything with some padding
		\draw[black, thin] (-2.5,-2.5) rectangle (4.5,2.8);
		
	
	\end{tikzpicture}
	
	\only<4->{
		The standard measure is the so-called Jaccard similarity.
    \[
		0 \leq \frac{\strut\alt<5>{8}{A \cap B}}{A \cup B} \leq 1 
		\]
	}

\end{frame}
\end{document}
```

Instead of `\only` the following uses `\visible` for your maths:

```
\documentclass{beamer}
\usepackage{tikz}
\begin{document}

\begin{frame}[fragile]
  \frametitle{Title}

  \vspace{-0.1cm}  % Reduce space after title
  We are interested in how similar two sets are.
  \vspace{0.4cm}   % Increase space before tikzpicture

  \centering
  \begin{tikzpicture}
    % Add a box around everything with some padding
    \draw[black, thin] (-2.5,-2.5) rectangle (4.5,2.8);


  \end{tikzpicture}

  \visible<4->{%
    The standard measure is the so-called Jaccard similarity.
    \[
      0 \leq \frac{\vphantom{A \cap B}\only<4>{A \cap B}\only<5>{8}}{A \cup B} \leq 1
    \]
  }%
\end{frame}
\end{document}
```

    \end{tikzpicture}

    \only<4->{
        The standard measure is the so-called Jaccard similarity.
    }

    \only<1-3>{\[\vphantom{0 \leq \frac{A \cap B}{A \cup B} \leq 1}\]} % Reserve space for the equation
    \only<4>{\[
        0 \leq \frac{A \cap B}{A \cup B} \leq 1
        \]
    }

    \only<5>{\[
        0 \leq \frac{8}{A \cup B} \leq 1
        \]
    }

\end{frame}

\end{document}
```

This helps a bit but not completely.
